  • /usr/bin/sshd isn't linked against PAM on one of my systems. What is wrong and how can I fix it?

  • Creating PHP Forms with show/hide functionality [migrated]

    - by ronquiq
    I want to create two reports and submit the report data to database by using two functions defined in a class: Here I have two buttons: "Create ES" and "Create RP". Rightnow, my forms are working fine, I can insert data successfully, but the problem was when I click on submit after filling the form data, the content is hiding and displays the fist div content "cs_content" and again I need to onclick to submit again. Could anyone give a solution for this. Requirement : When I click on "Create CS", I should be able to fill the form and submit data successfully with a message within "cs_content" and any form input errors, the errors should display within "cs_content". When I click on "Create RP", I should be able to fill the form and submit data successfully with a message within "rp_content" and any form input errors, the errors should display within "rp_content". home.php <?php require 'classes/class.report.php'; $report = new Report($db); ?> <html> <head> <script src="js/jqueryv1.10.2.js"></script> <script> $ (document).ready(function () { //$("#cs_content").show(); $('#cs').click(function () { $('#cs_content').fadeIn('slow'); $('#rp_content').hide(); }); $('#rp').click(function () { $('#rp_content').fadeIn('slow'); $('#cs_content').hide(); }); }); </script> </head> <body> <div class="container2"> <div style="margin:0px 0px;padding:3px 217px;overflow:hidden;"> <div id="cs" style="float:left;margin:0px 0px;padding:7px;"><input type="button" value="CREATE CS"></div> <div id="rp" style="float:left;margin:0px 0px;padding:7px;"><input type="button" value="CREATE RP"></div><br> </div> <div id="cs_content"> <?php $report->create_cs_report(); ?> </div> <div id="rp_content" style="display:none;"> <?php $report->create_rp_report(); ?> </div> </div> </body> </html> class.report.php <?php class Report { private $db; public function __construct($database){ $this->db = $database; } public function create_cs_report() { if (isset($_POST['create_es_report'])) { $report_name = htmlentities($_POST['report_name']); $from_address = htmlentities($_POST['from_address']); $subject = htmlentities($_POST['subject']); $reply_to = htmlentities($_POST['reply_to']); if (empty($_POST['report_name']) || empty($_POST['from_address']) || empty($_POST['subject']) || empty($_POST['reply_to'])) { $errors[] = '<span class="error">All fields are required.</span>'; } else { if (isset($_POST['report_name']) && empty($_POST['report_name'])) { $errors[] = '<span class="error">Report Name is required</span>'; } else if (!ctype_alnum($_POST['report_name'])) { $errors[] = '<span class="error">Report Name: Whitespace is not allowed, only alphabets and numbers are required</span>'; } if (isset($_POST['from_address']) && empty($_POST['from_address'])) { $errors[] = '<span class="error">From address is required</span>'; } else if (filter_var($_POST['from_address'], FILTER_VALIDATE_EMAIL) === false) { $errors[] = '<span class="error">Please enter a valid From address</span>'; } if (isset($_POST['subject']) && empty($_POST['subject'])) { $errors[] = '<span class="error">Subject is required</span>'; } else if (!ctype_alnum($_POST['subject'])) { $errors[] = '<span class="error">Subject: Whitespace is not allowed, only alphabets and numbers are required</span>'; } if (isset($_POST['reply_to']) && empty($_POST['reply_to'])) { $errors[] = '<span class="error">Reply To is required</span>'; } else if (filter_var($_POST['reply_to'], FILTER_VALIDATE_EMAIL) === false) { $errors[] = '<span class="error">Please enter a valid Reply-To address</span>'; } } if (empty($errors) === true) { $query = $this->db->prepare("INSERT INTO report(report_name, from_address, subject, reply_to) VALUES (?, ?, ?, ?)

  • Apache URL rewriting in reverse proxy

    - by Jeremy Gooch
    I'm deploying Apache in front of a Karaf-hosted application (Apache and Karaf are on separate servers). I want Apache to operate as a reverse proxy and also to hide part of the URL. The URL to get the log-in page of the application directly from the app server is http://app-server:8181/jellyfish. Pages are served by the Jetty instance running within Karaf. Of course, this behaviour would usually be blocked by the firewall for everything except the reverse proxy server. With the firewall off, if you hit this URL then Jetty loads the log-in page. The browser's address bar correctly changes to http://app-server:8181/jellyfish/login?0 and everything works. What I want is for http://web-server (i.e. from the root) to map to Jetty on the app server with the name of the app (jellyfish) suppressed. e.g. The browser would change to show http://web-server/login?0 in the address bar and all subsequent URLs and content would be served with the web-server's domain and without the jellyfish clutter. I can get Apache to operate as a simple reverse proxy, using the following config (snippet):- ProxyPass /jellyfish http://app-server:8181/jellyfish ProxyPassReverse / http://app-server:8181/ ...but this requires the browser's URL to contain jellyfish and going to the root URL (http://web-server) gives a 404 Not Found. I've spent a lot of time trying to use mod_rewrite with and without its [P] flag to get around this, but without success. I then tried the ProxyPassMatch directive, but I can't seem to get that quite correct either. Here's the current config, as is loaded into /etc/apache2/sites-available/ on the web server. Note that there is a locally-hosted images directory. I've also kept the mod_rewrite proxy exploit protection and am suppressing a couple of mod_security rules that were giving false positives. <VirtualHost *:80> ServerAdmin admin@drummer-server ServerName drummer-server ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /images/ "/var/www/images/" RewriteEngine On RewriteCond %{REQUEST_URI} !^$ RewriteCond %{REQUEST_URI} !^/ RewriteRule .* - [R=400,L] ProxyPass /images ! ProxyPassMatch ^/(.*) http://granny-server:8181/jellyfish/$1 ProxyPassReverse / http://granny-server:8181/jellyfish ProxyPreserveHost On SecRuleRemoveById 981059 981060 <Directory "/var/www/images"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost> If I go to http://web-server, I get redirected to http://web-server/jellyfish/home but this gives a 404, with a complaint about trying to access /jellyfish/jellyfish/home - NB the browser's address bar does not contain the double /jellyfish. HTTP ERROR 404 Problem accessing /jellyfish/jellyfish/home. Reason: Not Found And, if I go to http://web-server/login, I get redirected to http://web-server/jellyfish/login?0 but this gives a 404, with a complaint about trying to access /jellyfish/jellyfish/login. HTTP ERROR 404 Problem accessing /jellyfish/jellyfish/login. Reason: Not Found So, I'm guessing I'm somehow passing through the rules twice. I am also slightly bemused as to where the home bit of the URL comes from in the first example. Can someone point me in the right direction, please? Thanks, J.

  • Trouble in Nginx hotlink protection

    - by Ayaz Malik
    I am trying to implement image hotlink protection problem in nginx and I need help. I have a huge issue of my site's images being submitted to social networks like StumbleUpon with a direct link like http://example.com/xxxxx.jpg Which sometimes gets huge traffic and increases CPU usage and bandwidth usage. I want to block direct access to my images from other referrers and protect them from being hotlinked. Here is the code from my vhost.conf server { access_log off; error_log logs/vhost-error_log warn; listen 80; server_name mydomain.com www.mydomain.com; # uncomment location below to make nginx serve static files instead of Apache # NOTE this will cause issues with bandwidth accounting as files wont be logged location ~* \.(gif|jpg|jpeg|png|wmv|avi|mpg|mpeg|mp4|htm|html|js|css)$ { root /home/username/public_html; expires 1d; } root /home/mydomain/public_html; } location / { client_max_body_size 10m; client_body_buffer_size 128k; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; # you can increase proxy_buffers here to suppress "an upstream response # is buffered to a temporary file" warning proxy_buffers 16 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_connect_timeout 30s; proxy_redirect http://www.mydomain.com:81 http://www.mydomain.com; proxy_redirect http://mydomain.com:81 http://mydomain.com; proxy_pass http://ip_address/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; expires 24h; } } For hotlink protection I added this code location ~* (\.jpg|\.png|\.gif|\.jpeg)$ { valid_referers blocked www.mydomain.com mydomain.com; if ($invalid_referer) { return 403; } This is the current nginx code for this domain, but it didn't work: server { access_log off; error_log logs/vhost-error_log warn; listen 80; server_name mydomain.com www.mydomain.com; # uncomment location below to make nginx serve static files instead of Apache # NOTE this will cause issues with bandwidth accounting as files wont be logged location ~* \.(gif|jpg|jpeg|png|wmv|avi|mpg|mpeg|mp4|htm|html|js|css)$ { root /home/username/public_html; expires 1d; } root /home/mydomain/public_html; } location ~* (\.jpg|\.png|\.gif|\.jpeg)$ { valid_referers blocked www.mydomain.com mydomain.com; if ($invalid_referer) { return 403; } location / { client_max_body_size 10m; client_body_buffer_size 128k; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; # you can increase proxy_buffers here to suppress "an upstream response # is buffered to a temporary file" warning proxy_buffers 16 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_connect_timeout 30s; proxy_redirect http://www.mydomain.com:81 http://www.mydomain.com; proxy_redirect http://mydomain.com:81 http://mydomain.com; proxy_pass http://ip_address/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; expires 24h; } } How can I fix this?

    - by Totty
    I'm using this in a local LAN so it should be quite fast.

  • Issue in nginx proxying to apache

    - by Luis Masuelli
    My current nginx configuration is as follows: specific configuration for (currently two) domains: server { listen 443 ssl; server_name studiotv.service.tebusco.lan phpmyadmin.service.tebusco.lan; ssl_certificate /home/administrador/nginx-confs/ssl/service.tebusco.lan.crt; ssl_certificate_key /home/administrador/nginx-confs/ssl/service.tebusco.lan.key; location / { proxy_pass http://127.0.0.1:8180; proxy_set_header Host $http_host:8180; } } default configuration for unmatched ssl connections: server { listen 443 default ssl; ssl_certificate /home/administrador/nginx-confs/ssl/service.tebusco.lan.crt; ssl_certificate_key /home/administrador/nginx-confs/ssl/service.tebusco.lan.key; location / { return 403; } } http configuration: server { listen 80; rewrite ^ https://$host$request_uri? permanent; } The intention is clear: Redirect http traffic to https. Proxy each https:// call from phpmyadmin.service.tebusco.lan and studiotv.service.tebusco.lan to apache2. This includes passing a host header, which is detected. Each unmatched ssl connection must return a 403 in nginx. Does not even reach apache2. In the apache2 side of the life, I have a default site, and a non-default site which will match studiotv.service.tebusco.lan: 000-default.conf file (available and enabled): <VirtualHost 127.0.0.1:8180> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. ServerName localhost ServerAdmin webmaster@localhost DocumentRoot /var/www/html <Directory /var/www/html> Order deny,allow Require all granted </Directory> </VirtualHost> # vim: syntax=apache ts=4 sw=4 sts=4 sr noet studiotv.conf file (available and enabled): <VirtualHost *:8180> ServerName studiotv.service.tebusco.lan ServerAdmin [email protected] DocumentRoot /var/www/studiotv <Directory /var/www/studiotv/> Options -Indexes +FollowSymLinks AllowOverride None Order deny,allow Allow from all Require all granted </Directory> # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn # No usamos ${APACHE_LOG_DIR} sino en su lugar /var/log/<host> ErrorLog /var/log/apache2/studiotv/error.log CustomLog /var/log/apache2/studiotv/access.log combined </VirtualHost> # vim: syntax=apache ts=4 sw=4 sts=4 sr noet However, when I hit the browser with http://studiotv.service.tebusco.lan, the default php page is shown instead. Question: What am I missing? (apache 2.4.7, nginx 1.6.0, ubuntu server 14.04).

The workstation is also running Mac OS X 10.6 Snow Leopard, when the user logs in and tries to run our primary application which they're explicitly allowed to run (via the group's preferences), it says "You don't have permission to use the application 'Blah'". Now, the application is added to the group's list of always allowed applications, unsigned (so a minor difference in application version or file contents shouldn't disallow it). It even lives in a subdirectory of /Applications which is in the list of folders to allow applications. I've run into this when logging this user into new workstations and the following usually works: Log them out Remove the following files from their mobile home folder on the workstation: /Library/Managed\ Preferences/, ~/.FileSync, ~/Library/Preferences/com.apple.finder.plist, and ~/Library/Preferences/com.apple.MCX.plist. Remove the following files from their network home folder on the server: ~/.FileSync, ~/Library/Preferences/com.apple.finder.plist, and ~/Library/Preferences/com.apple.MCX.plist. Log them back in on the workstation. However, this no longer resolves the issue. Their Home Sync preferences are set (on the group) to sync ~, but not the following files (manually, at login, and at logout... no background sync here): ~/.SymAVQSFile ~/NAVMac800QSFile ~/Library ~/.FileSync ~/.account Their Preferences Sync preferences are set (also on the group) to sync ~/Library & ~/Documents/Microsoft User Data, but not the following files (also manually, at login, and at logout... no background sync): ~/.SymAVQSFile ~/.Trash ~/.Trashes ~/Documents/Microsoft User Data/Entourage Temp ~/Library/Application Support/SyncServices ~/Library/Application Support/MobileSync ~/Library/Caches ~/Library/Calendars/Calendar Cache ~/Library/Logs ~/Library/Mail/AvailableFeeds ~/Library/Mail/Envelope Index ~/Library/Preferences/Macromedia/ ~/Library/Printers ~/Library/PubSub/Database ~/Library/PubSub/Downloads ~/Library/PubSub/Feeds ~/Library/Safari/Icons.db ~/Library/Safari/HistoryIndex.sk ~/Library/iTunes/iPhone Software Updates IMAP-* Exchange-* EWS-* Mac-* ~/Library/Preferences/ByHost ~/Library/Preferences/com.apple.dock.plist ~/Library/Preferences/com.apple.sitebarlists.plist ~/Library/Application Support/4D ~/Library/Preferences/com.apple.MCX.plist ~/.FileSync ~/.account Even with ~/Library/Preferences/com.apple.MCX.plist prevented from syncing during a Preferences Sync, it still seems to show up in the network home on the server frequently. Are there any other files other than ~/Library/Preferences/com.apple.MCX.plist that contain application Managed Preferences that might be causing this one app to be showing up as not allowed? Any ideas on how ~/Library/Preferences/com.apple.MCX.plist keeps getting sync'd back up the network home folder on the server? Update: I thought I had found a workaround this morning, but it also seemed to be extremely temporary. Basically, loking at /Library/Managed\ Preferences/[shortname]/com.apple.applicationaccess.new.plist I discovered that it didn't have an entry for the application in question, but /Library/Managed\ Preferences/[shortname]/complete.plist did. Naturally, I deleted com.apple.applicationaccess.new.plist, logged in again, and it worked... on one workstation. It failed on others, and after logging out & back in a couple more times it started failing on all of them again, even after further deletions of com.apple.applicationaccess.new.plist. Oddly, com.apple.applicationaccess.new.plist & complete.plist do both contain an entry for the application in question now, but it still says it's not allowed. Further Update: Okay, so I now have a reproducible workaround which seems to be required after every reboot of the workstation: Log in as the user (you'll discover you cannot launch the application in question). Fast User Switch to the local admin account on the workstation (we always have one on every machine). From that local admin account, run sudo mcxrefresh -n 'shortname' (logging out and back in as the user in question will not work). Fast User Switch back to the user (you'll still not be allowed to run the application). Log the user out and back in (you'll now be able to run the application in question.) Fast User Switch back to the local admin account, log it out, and log back in as the user in question. If you do all that exactly as described it'll keep working through log out & log back in, but NOT through a reboot. If, after a reboot, you try something like logging in as the local admin account, running sudo mcxrefresh -n 'shortname', logging out, then logging in as the user in question, it will NOT work. Yet Another Update We don't have any computer groups in our Open Directory, so it shouldn't be getting any conflicting settings from there. I ran sudo mcxquery -format xml -user shortname -group groupname before & after performing the aforementioned process to allow the application in question to be run and the results were identical (saved the result to files & diff'd... I'm not just guessing here). One Step Forward, Half a Step Back: When the Mac OS X 10.6.5 Server update was released, we upgraded our Open Directory Master to it as the changes included the following managed preferences fixes which I hoped might address this issue: Addresses an issue that could prevent managed preferences from being applied when a user logs in on a workstation that has been idle. Fixes an issue that could prevent administrators from bypassing client management settings on a workstation. This seemed to improve the situation slightly. The application in question now usually launches without error. If, and when it does launch with the "You don't have permission to use the application" error, logging the user out and back in seems to correct it. That said, we've since had to add a couple of applications to the user's ~/Applications/ directory and those are still prevented from launching. The workstations are running Mac OS X 10.6.4, the OD Master (which the workstations are bound to) is running Mac OS 10.6.5 Server (although there are two OD Replicas still running 10.6.4 Server), and we're using Workgroup Manager 10.6.3 (which is included with the Server Admin Tools 10.6.5 upgrade) to add the applications (unsigned, as always). This time, I've caught the following in /var/log/system.log when attempting to launch one of the allowed applications from ~/Applications: Dec 22 17:36:24 hostname parentalcontrolsd[43221]: -[ActivityTracker checkApp:csFlags:] [954:username] -- *** Incoming app appears to be masquerading as white listed app and failed signature validation: /Users/username/Applications/FileMaker Pro 5.5/FileMaker Pro.app/Contents/MacOS/FileMaker Pro.

  • Scan a Windows PC for Viruses from a Ubuntu Live CD

    - by Trevor Bekolay
    Getting a virus is bad. Getting a virus that causes your computer to crash when you reboot is even worse. We’ll show you how to clean viruses from your computer even if you can’t boot into Windows by using a virus scanner in a Ubuntu Live CD. There are a number of virus scanners available for Ubuntu, but we’ve found that avast! is the best choice, with great detection rates and usability. Unfortunately, avast! does not have a proper 64-bit version, and forcing the install does not work properly. If you want to use avast! to scan for viruses, then ensure that you have a 32-bit Ubuntu Live CD. If you currently have a 64-bit Ubuntu Live CD on a bootable flash drive, it does not take long to wipe your flash drive and go through our guide again and select normal (32-bit) Ubuntu 9.10 instead of the x64 edition. For the purposes of fixing your Windows installation, the 64-bit Live CD will not provide any benefits. Once Ubuntu 9.10 boots up, open up Firefox by clicking on its icon in the top panel. Navigate to http://www.avast.com/linux-home-edition. Click on the Download tab, and then click on the link to download the DEB package. Save it to the default location. While avast! is downloading, click on the link to the registration form on the download page. Fill in the registration form if you do not already have a trial license for avast!. By the time you’ve filled out the registration form, avast! will hopefully be finished downloading. Open a terminal window by clicking on Applications in the top-left corner of the screen, then expanding the Accessories menu and clicking on Terminal. In the terminal window, type in the following commands, pressing enter after each line. cd Downloadssudo dpkg –i avast* This will install avast! on the live Ubuntu environment. To ensure that you can use the latest virus database, while still in the terminal window, type in the following command: sudo sysctl –w kernel.shmmax=128000000 Now we’re ready to open avast!. Click on Applications on the top-left corner of the screen, expand the Accessories folder, and click on the new avast! Antivirus item. You will first be greeted with a window that asks for your license key. Hopefully you’ve received it in your email by now; open the email that avast! sends you, copy the license key, and paste it in the Registration window. avast! Antivirus will open. You’ll notice that the virus database is outdated. Click on the Update database button and avast! will start downloading the latest virus database. To scan your Windows hard drive, you will need to “mount” it. While the virus database is downloading, click on Places on the top-left of your screen, and click on your Windows hard drive, if you can tell which one it is by its size. If you can’t tell which is the correct hard drive, then click on Computer and check out each hard drive until you find the right one. When you find it, make a note of the drive’s label, which appears in the menu bar of the file browser. Also note that your hard drive will now appear on your desktop. By now, your virus database should be updated. At the time this article was written, the most recent version was 100404-0. In the main avast! window, click on the radio button next to Selected folders and then click on the “+” button to the right of the list box. It will open up a dialog box to browse to a location. To find your Windows hard drive, click on the “>” next to the computer icon. In the expanded list, find the folder labelled “media” and click on the “>” next to it to expand it. In this list, you should be able to find the label that corresponds to your Windows hard drive. If you want to scan a certain folder, then you can go further into this hierarchy and select that folder. However, we will scan the entire hard drive, so we’ll just press OK. Click on Start scan and avast! will start scanning your hard drive. If a virus is found, you’ll be prompted to select an action. If you know that the file is a virus, then you can Delete it, but there is the possibility of false positives, so you can also choose Move to chest to quarantine it. When avast! is done scanning, it will summarize what it found on your hard drive. You can take different actions on those files at this time by right-clicking on them and selecting the appropriate action. When you’re done, click Close. Your Windows PC is now free of viruses, in the eyes of avast!. Reboot your computer and with any luck it will now boot up! Alternatives to avast! If avast! and a liberal amount of Googling doesn’t fix your problem, it’s possible that a different virus scanner will fix your obscure issue. Here are a list of other virus scanners available for Ubuntu that are either free or offer free trials. See their support forums for help on installing these virus scanners. Avira AntiVir Personal for Linux / Solaris Panda Antivirus for Linux Installation and usage guide from Ubuntu F-PROT Antivirus for Linux ClamAV installation and usage guide from Ubuntu NOD32 Antivirus for Linux Kaspersky Anti-Virus 2010 Bitdefender Antivirus for Unices Conclusion Running avast! from a Ubuntu Live CD can clean the vast majority of viruses from your Windows PC. This is another reason to always have a Ubuntu Live CD ready just in case something happens to your Windows installation!

  • Having trouble binding a ksoap object to an ArrayList in Android

    - by Maskau
    I'm working on an app that calls a web service, then the webservice returns an array list. My problem is I am having trouble getting the data into the ArrayList and then displaying in a ListView. Any ideas what I am doing wrong? I know for a fact the web service returns an ArrayList. Everything seems to be working fine, just no data in the ListView or the ArrayList.....Thanks in advance!

  • ASP.NET MVC & Silverlight development - on Ubuntu

    - by queen3
    I recently moved my working environment from Windows 7 to Ubuntu, and enjoy this every minute of my working day. My work is currently to develop ASP.NET MVC and Silverlight applications. Thus, important Windows stuff is being still run in VirtualBox (such as IIS, MSSQL, Silverlight 3, and legacy COM stuff). For now, I use Visual Studio under VirtualBox as editor/IDE/debugger. But since I prefer Ubuntu fonts and UI much more I'd like to move at least editor (and better IDE) to native Ubuntu. Things I have already done: I store project files in my home folder and run Visual Studio from \vboxsvr share. With few tricks for ASP.NET it works. I use svn on Ubuntu. I test my ASP.NET MVC site using FireFox/FireBug on Ubuntu. What I need on Ubuntu: SQL client to manage MSSQL. I mostly need querying, but I would miss SQL intellisense support. I enjoy command-line svn a lot, but there're times when it's not enough (e.g. view files / check diffs / selectively commit at the sames time) so I wonder if there're any addons - I don't mean replacement for svn, just addons for rare cases like above. I wonder if there're editors that can provide some C# intellisense. Yes I know about MonoDevelop, but will it provide intellisense without compiling (since I'm going to compile remotely in Win box)? And pretty big topic, what's the best way (editor/IDE) to do "folder-based" development? What I mean: The project is /trunk. Everything is there. I don't want to manually add files to project or like that. The project is the folder and files down there. Main task is to edit files of course. I need a quick way to open / search for files in the project. Like in Resharper, I can click Ctrl-Shift-T (IIRC) and just type file name, a list of matching files in the project folder and below is shown. For example, gedit has file tree browser, but I can't quickly type XYZ to find all XYZ files there; moreover it doesn't automatically switch focus to/from editor; so it's more mouse-oriented; I need 100% keyboard way. I need syntax highlighting for C#/HTML/JS. Most importantly, I need HTML tags autocompletion. I can live without it, but I'll be sorry. I need to run compilation remotely (via ssh I think, invoking NAnt script which does MSBuild) and grab results such as errors and warnings, and I'd prefer to quickly go to error line/file. In short, I need to edit/search/open/svn/compile/run files in some folder. Looks like a case for command-line, but imaging I'm in /trunk and want to open file.cs inside /trunk/foo/bar/boo/far, I wouldn't want to type all this path even with bash autocompletion help. I'd prefer to enter :open file.cs, and maybe then select from list of file.cs and file1.cs. Well, maybe I'll add more soon. Actually, I don't have exact requirements; for example, I don't even know if I need to ask for IDE or editor; or should it have svn support integrated or I need to use it from console; do people work with files from console (search/commit/delete/etc) and open editor from there, or they work from editor/IDE and manage files (search/commit/delete) from there? What's better? I have a feeling that vim might have everything I need. I'd like to confirm that, before I spend a lot of time learning it. No I don't want Emacs. Any other IDE? I like Eclipse, but is it good for such stuff? And after all, do you feel like it's a good way to go? I enjoy Ubuntu, enjoy learning new stuff, and Ubuntu + Windows in VirtualBox actually runs faster than Windows7 on my mahcine, but maybe I need to keep development (editor/files management/etc) in Windows/VirtualBox only, leaving other stuff for Ubuntu?

  • Integrating Flickr with ASP.Net application

    - by sreejukg
    Flickr is the popular photo management and sharing application offered by yahoo. The services from flicker allow you to store and share photos and videos online. Flicker offers strong API support for almost all services they provide. Using this API, developers can integrate photos to their public website. Since 2005, developers have collaborated on top of Flickr's APIs to build fun, creative, and gorgeous experiences around photos that extend beyond Flickr. In this article I am going to demonstrate how easily you can bring the photos stored on flicker to your website. Let me explain the scenario this article is trying to address. I have a flicker account where I upload photos and share in many ways offered by Flickr. Now I have a public website, instead of re-upload the photos again to public website, I want to show this from Flickr. Also I need complete control over what photo to display. So I went and referred the Flickr documentation and there is API support ready to address my scenario (and more… ). FlickerAPI for ASP.Net To Integrate Flicker with ASP.Net applications, there is a library available in CodePlex. You can find it here http://flickrnet.codeplex.com/ Visit the URL and download the latest version. The download includes a Zip file, when you unzip you will get a number of dlls. Since I am going to use ASP.Net application, I need FlickrNet.dll. See the screenshot of all the dlls, and there is a help file available in the download (.chm) for your reference. Once you have the dll, you need to use Flickr API from your website. I assume you have a flicker account and you are familiar with Flicker services. Arrange your photos using Sets in Flickr In flicker, you can define sets and add your uploaded photos to sets. You can compare set to photo album. A set is a logical collection of photos, which is an excellent option for you to categorize your photos. Typically you will have a number of sets each set having few photos. You can write application that brings photos from sets to your website. For the purpose of this article I already created a set Flickr and added some photos to it. Once you logged in to Flickr, you can see the Sets under the Menu. In the Sets page, you will see all the sets you have created. As you notice, you can see certain sample images I have uploaded just to test the functionality. Though I wish I couldn’t create good photos so please bear with me. I have created 2 photo sets named Blue Album and Red Album. Click on the image for the set, will take you to the corresponding set page. In the set “Red Album” there are 4 photos and the set has a unique ID (highlighted in the URL). You can simply retrieve the photos with the set id from your application. In this article I am going to retrieve the images from Red album in my ASP.Net page. For that First I need to setup FlickrAPI for my usage. Configure Flickr API Key As I mentioned, we are going to use Flickr API to retrieve the photos stored in Flickr. In order to get access to Flickr API, you need an API key. To create an API key, navigate to the URL http://www.flickr.com/services/apps/create/ Click on Request an API key link, now you need to tell Flickr whether your application in commercial or non-commercial. I have selected a non-commercial key. Now you need to enter certain information about your application. Once you enter the details, Click on the submit button. Now Flickr will create the API key for your application. Generating non-commercial API key is very easy, in couple of steps the key will be generated and you can use the key in your application immediately. ASP.Net application for retrieving photos Now we need write an ASP.Net application that display pictures from Flickr. Create an empty web application (I named this as FlickerIntegration) and add a reference to FlickerNet.dll. Add a web form page to the application where you will retrieve and display photos(I have named this as Gallery.aspx). After doing all these, the solution explorer will look similar to following. I have used the below code in the Gallery.aspx page. The output for the above code is as follows. I am going to explain the code line by line here. First it is adding a reference to the FlickrNet namespace. using FlickrNet; Then create a Flickr object by using your API key. Flickr f = new Flickr("<yourAPIKey>"); Now when you retrieve photos, you can decide what all fields you need to retrieve from Flickr. Every photo in Flickr contains lots of information. Retrieving all will affect the performance. For the demonstration purpose, I have retrieved all the available fields as follows. PhotoSearchExtras.All But if you want to specify the fields you can use logical OR operator(|). For e.g. the following statement will retrieve owner name and date taken. PhotoSearchExtras extraInfo = PhotoSearchExtras.OwnerName | PhotoSearchExtras.DateTaken; Then retrieve all the photos from a photo set using PhotoSetsGetPhotos method. I have passed the PhotoSearchExtras object created earlier. PhotosetPhotoCollection photos = f.PhotosetsGetPhotos("72157629872940852", extraInfo); The PhotoSetsGetPhotos method will return a collection of Photo objects. You can just navigate through the collection using a foreach statement. foreach (Photo p in photos) {     //access each photo properties } Photo class have lot of properties that map with the properties from Flickr. The chm documentation comes along with the CodePlex download is a great asset for you to understand the fields. In the above code I just used the following p.LargeUrl – retrieves the large image url for the photo. p.ThumbnailUrl – retrieves the thumbnail url for the photo p.Title – retrieves the Title of the photo p.DateUploaded – retrieves the date of upload Visual Studio intellisense will give you all properties, so it is easy, you can just try with Visual Studio intellisense to find the right properties you are looking for. Most of hem are self-explanatory. So you can try retrieving the required properties. In the above code, I just pushed the photos to the page. In real time you can use the retrieved photos along with JQuery libraries to create animated photo galleries, slideshows etc. Configuration and Troubleshooting If you get access denied error while executing the code, you need to disable the caching in Flickr API. FlickrNet cache the photos to your local disk when retrieved. You can specify a cache folder where the application need write permission. You can specify the Cache folder in the code as follows. Flickr.CacheLocation = Server.MapPath("./FlickerCache/"); If the application doesn’t have have write permission to the cache folder, the application will throw access denied error. If you cannot give write permission to the cache folder, then you must disable the caching. You can do this from code as follows. Flickr.CacheDisabled = true; Disabling cache will have an impact on the performance. Take care! Also you can define the Flickr settings in web.config file.You can find the documentation here. http://flickrnet.codeplex.com/wikipage?title=ExampleConfigFile&ProjectName=flickrnet Flickr is a great place for storing and sharing photos. The API access allows developers to do seamless integration with the photos uploaded on Flickr.

  • New Validation Attributes in ASP.NET MVC 3 Future

    - by imran_ku07
         Introduction:             Validating user inputs is an very important step in collecting information from users because it helps you to prevent errors during processing data. Incomplete or improperly formatted user inputs will create lot of problems for your application. Fortunately, ASP.NET MVC 3 makes it very easy to validate most common input validations. ASP.NET MVC 3 includes Required, StringLength, Range, RegularExpression, Compare and Remote validation attributes for common input validation scenarios. These validation attributes validates most of your user inputs but still validation for Email, File Extension, Credit Card, URL, etc are missing. Fortunately, some of these validation attributes are available in ASP.NET MVC 3 Future. In this article, I will show you how to leverage Email, Url, CreditCard and FileExtensions validation attributes(which are available in ASP.NET MVC 3 Future) in ASP.NET MVC 3 application.       Description:             First of all you need to download ASP.NET MVC 3 RTM Source Code from here. Then extract all files in a folder. Then open MvcFutures project from mvc3-rtm-sources\mvc3\src\MvcFutures folder. Build the project. In case, if you get compile time error(s) then simply remove the reference of System.Web.WebPages and System.Web.Mvc assemblies and add the reference of System.Web.WebPages and System.Web.Mvc 3 assemblies again but from the .NET tab and then build the project again, it will create a Microsoft.Web.Mvc assembly inside mvc3-rtm-sources\mvc3\src\MvcFutures\obj\Debug folder. Now we can use Microsoft.Web.Mvc assembly inside our application.             Create a new ASP.NET MVC 3 application. For demonstration purpose, I will create a dummy model UserInformation. So create a new class file UserInformation.cs inside Model folder and add the following code,   public class UserInformation { [Required] public string Name { get; set; } [Required] [EmailAddress] public string Email { get; set; } [Required] [Url] public string Website { get; set; } [Required] [CreditCard] public string CreditCard { get; set; } [Required] [FileExtensions(Extensions = "jpg,jpeg")] public string Image { get; set; } }             Inside UserInformation class, I am using Email, Url, CreditCard and FileExtensions validation attributes which are defined in Microsoft.Web.Mvc assembly. By default FileExtensionsAttribute allows png, jpg, jpeg and gif extensions. You can override this by using Extensions property of FileExtensionsAttribute class.             Then just open(or create) HomeController.cs file and add the following code,   public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(UserInformation u) { return View(); } }             Next just open(or create) Index view for Home controller and add the following code,  @model NewValidationAttributesinASPNETMVC3Future.Model.UserInformation @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Index</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>UserInformation</legend> <div class="editor-label"> @Html.LabelFor(model => model.Name) </div> <div class="editor-field"> @Html.EditorFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) </div> <div class="editor-label"> @Html.LabelFor(model => model.Email) </div> <div class="editor-field"> @Html.EditorFor(model => model.Email) @Html.ValidationMessageFor(model => model.Email) </div> <div class="editor-label"> @Html.LabelFor(model => model.Website) </div> <div class="editor-field"> @Html.EditorFor(model => model.Website) @Html.ValidationMessageFor(model => model.Website) </div> <div class="editor-label"> @Html.LabelFor(model => model.CreditCard) </div> <div class="editor-field"> @Html.EditorFor(model => model.CreditCard) @Html.ValidationMessageFor(model => model.CreditCard) </div> <div class="editor-label"> @Html.LabelFor(model => model.Image) </div> <div class="editor-field"> @Html.EditorFor(model => model.Image) @Html.ValidationMessageFor(model => model.Image) </div> <p> <input type="submit" value="Save" /> </p> </fieldset> } <div> @Html.ActionLink("Back to List", "Index") </div>             Now just run your application. You will find that both client side and server side validation for the above validation attributes works smoothly.                      Summary:             Email, URL, Credit Card and File Extension input validations are very common. In this article, I showed you how you can validate these input validations into your application. I explained this with an example. I am also attaching a sample application which also includes Microsoft.Web.Mvc.dll. So you can add a reference of Microsoft.Web.Mvc assembly directly instead of doing any manual work. Hope you will enjoy this article too.   SyntaxHighlighter.all()

  • User Experience Highlights in PeopleSoft and PeopleTools: Direct from Jeff Robbins

    - by mvaughan
    By Kathy Miedema, Oracle Applications User Experience  This is the fifth in a series of blog posts on the user experience (UX) highlights in various Oracle product families. The last posted interview was with Nadia Bendjedou, Senior Director, Product Strategy on upcoming Oracle E-Business Suite user experience highlights. You’ll see themes around productivity and efficiency, and get an early look at the latest mobile offerings coming through these product lines. Today’s post is on the user experience in PeopleSoft and PeopleTools. To learn more about what’s ahead, attend PeopleSoft or PeopleTools OpenWorld presentations.This interview is with Jeff Robbins, Senior Director, PeopleSoft Development. Jeff Robbins Q: How would you describe the vision you have for the user experience of PeopleSoft?A: Intuitive – Specifically, customers use PeopleSoft to help their employees do their day-to-day work, and the UI (user interface) has been helpful and assistive in that effort. If it’s not obvious what they need to do a task, then the UI isn’t working. So the application needs to make it simple for users to find information they need, complete a task, do all the things they are responsible for, and it really helps when the UI just makes sense. Productive – PeopleSoft is a tool used to support people to do their work, and a lot of users are measured by how much work they’re able to get done per hour, per day, etc. The UI needs to help them be as productive as possible, and can’t make them waste time or energy. The UI needs to reflect the type of work necessary for a task -- if it's data entry, the UI needs to assist the user to get information into the system. For analysts, the UI needs help users assess or analyze information in a particular way. Innovative – The concept of the UI being innovative is something we’ve been working on for years. It’s not just that we want to be seen as innovative, the fact is that companies are asking their employees to do more than they’ve ever asked before. More often companies want to roll out processes as employee or manager self-service, where an employee is responsible to review and maintain their own data. So we’ve had to reinvent, and ask,  “How can we modify the ways an employee interacts with our applications so that they can be more productive and efficient – even with tasks that are entirely unfamiliar?”  Our focus on innovation has forced us to design new ways for users to interact with the entire application.Q: How are the UX features you have delivered so far resonating with customers?  A: Resonating very well. We’re hearing tremendous responses from users, managers, decision-makers -- who are very happy with the improved user experience. Many of the individual features resonate well. Some have really hit home, others are better than they used to be but show us that there’s still room for improvement.A couple innovations really stand out; features that have a significant effect on how users interact with PeopleSoft.First, the deployment of PeopleSoft in a way that’s more like a consumer website with the PeopleSoft Home page and Dashboards.  This new approach is very web-centric, where users feel they’re coming to a website rather than logging into an enterprise application.  There’s lots of information from all around the organization collected in a way that feels very familiar to users. In order to do your job, you can come to this web site rather than having to learn how to log into an application and figure out a complicated menu. Companies can host these really rich web sites for employees that are home pages for accessing critical tasks and information. The UI elements of incorporating search into the whole navigation process is another hit. Rather than having to log in and choose a task from a menu, users come to the web site and begin a task by simply searching for data: themselves, another employee, a customer record, whatever.  The search results include the data along with a set of actions the user might take, completely eliminating the need to hunt through a complicated system menu. Search-centric navigation is really sitting well with customers who are trying to deploy an intuitive set of systems. Q: Are any UX highlights more popular than you expected them to be?  A: We introduced a feature called Pivot Grid in the last release, which is a combination of an interactive grid, like an Excel Pivot Table, along with a dynamic visual chart that automatically graphs the data. I wasn’t certain at first how extensively this would be used. It looked like an innovative tool, but it wasn’t clear how it would be incorporated in business process applications. The fact is that everyone who sees Pivot Grids is thrilled with that kind of interactivity.  It reflects the amount of analytical thinking customers are asking employees to do. Employees can’t just enter data any more. They must interact with it, analyze it, and make decisions. Pivot Grids fit into this way of working. Q: What can you tell us about PeopleSoft’s mobile offerings?A: A lot of customers are finding that mobile is the chief priority in their organization.  They tell us they want their employees to be able to access company information from their mobile devices.  Of course, not everyone has the same requirements, so we’re working to make sure we can help our customers accomplish what they’re trying to do.  We’ve already delivered a number of mobile features.  For instance, PeopleSoft home pages, dashboards and workcenters all work well on an iPad, straight out of the box.  We’ve delivered a number of key functions and tasks for mobile workers – those who are responsible for using a mobile device to manage inventory, for example.  Customers tell us they also need a holistic strategy, one that allows their employees to access nearly every task from a mobile device.  While we don’t expect users to do extensive data entry from their smartphone, it makes sense that they have access to company information and systems while away from their desk.  That’s where our strategy is going now.  We plan to unveil a number of new mobile offerings at OpenWorld.  Some will be available then, some shortly after. Q: What else are you working on now that you think is going to be exciting to customers at Oracle OpenWorld?A: Our next release -- the big thing is PeopleSoft 9.2, and we’ll be talking about the huge amount of work that’s gone into the next versions. A new toolset, 8.53, will be coming, and there’s a lot to talk about there, and the next generation of PeopleSoft 9.2.  We have a ton of new stuff coming.Q: What do you want PeopleSoft customers to know? A: We have been focusing on the user experience in PeopleSoft as a very high priority for the last 4 years, and it’s had interesting effects. One thing is that the application is better, more usable.  We’ve made visible improvements. Another aspect is that in customers’ minds, the PeopleSoft brand is being reinvigorated. Customers invested in PeopleSoft years ago, and then they weren’t sure where PeopleSoft was going.  This investment in the UI and overall user experience keeps PeopleSoft current, innovative and fresh.  Customers  are able to take advantage of a lot of new features, even on the older applications, simply by upgrading their PeopleTools. The interest in that ability has been tremendous. Knowing they have a lot of these features available -- right now, that’s pretty huge. There’s been a tremendous amount of positive response, just on the fact that we’re focusing on the user experience.

  • Fixing a SkyDrive Sync Disaster

    - by Rick Strahl
    For a few months I've been using SkyDrive to handle some basic synching tasks for a number of folders of mine. Specifically I've been dumping a few of my development folders into sky drive so I have a live running backup. It had been working just fine until about a week ago when something went awry. Badly! The idea is that the SkyDrive should sync files, but somewhere in its sync relationship it appears that SkyDrive got confused and assumed it needed to sync back older files to my local machine from the SkyDrive server. So rather than syncing my newer files to the server SkyDrive was pushing older files back to me. Because SkyDrive is so slow actually updating data it's not unusual for SkyDrive to be far behind in syncing and apparently some files were out of date by several months. Of course this is insidious because I didn't notice it for quite some time. I'd been happily working away on my files when a few days ago I noted a bunch of files with -RasXps (my machine name) popping up in various folders. At first I thought my Git repository was giving me a fit, but eventually realized that SkyDrive was actually pushing old files into my monitored folders. To be fair SkyDrive did make backups of the existing files, but by the time I caught it there were literally a few thousand files scattered on my machine that were now updated with old files from online. Here's what some of this looks like: If you look at the directory list you see a bunch of files with a -RasXps postfix appended to them. Those are the files that SkyDrive replaced and backed up on my machine. As you can see the backed up files are actually newer than the ones it pulled from the online SkyDrive. Unless I modified the files after they were updated they all were older than the existing local files. Not exactly how I imagined my synching would work. At first I started cleaning up this mess manually. In most cases the obvious solution was to simply delete the original file and replace with the -RasXps file, but not in all files. Some scrutiny was required and besides being a pain in the ass to rename files, quite frequently I had to dig out Beyond Compare to compare a few files where it wasn't quite clear what's wrong. I quickly realized that doing this by hand would be too hard for the large number of files that got hosed. Hacking together a small .NET Utility So, I figured the easiest way to tackle this is to write a small utility app that shows me all the mangled files that have backups, allows me to compare them and then quickly select and update them, removing the -RasXps file after choosing one of the two files. What I ended up with was a quick and dirty WinForms app that allows me to pick a root folder, and then shows all the -MachineName files: I start by picking a base folder and a template to search for - typically the -MachineName. Clicking Go brings up a list of all files in that folder and its subdirectories.  The list also displays the dates for the saved (-MachineName) file and the current file on disk, along with highlighting for the newer of the two. I can right click on any file and get a context menu pop up to open the folder in Explorer, or open Beyond Compare and view the two files to compare differences which I found very helpful for a number of files where I had modified the files after SkyDrive had updated to an old one. Typically these would be the green files (of which there were thankfully few). To 'fix' files I can select any number of files in the list, then use one of the three buttons on the right to apply an operation. I can use the Saved files - that is the backup file that SkyDrive created with the -MachineName extension (-RasXps above). Or I can use the current file, which is the file with the right name on disk right now and delete the -MachineName file. Or on some occasions I can just opt to delete both of them. For some files like binaries it's often easier to just delete and them be rebuild than choosing. For the most part the process involves accepting the pink files, and checking the few green files and see if any modifications were made since the file was updated incorrectly by SkyDrive. For me luckily those are few in number. Anyways, I thought I share this utility in case anybody else runs into this issue. I've included the VS2012 solution and all the source code so you can see how it works and you can tweak it as needed. The .NET 4.5 binaries are also included if you can't compile. Be warned though!  This rough code is provided as is and makes no guarantees or claims about file safety. All three of the action buttons on the form will delete data. It's a very rough utility and there are no safeguards that ask nicely before deleting files. I highly recommend you make a backup before you have at it. This tools is very narrow in focus, but it might also work with other sync issues from other vendors. I seem to remember that I had similar issues with SugarSync at some point and it too created the -MachineName style files on sync conflicts. Hope this helps somebody out so you can avoid wasting the better part of a full work day on this… Resources Download the Source Code and Binaries for SkyDrive Rescue© Rick Strahl, West Wind Technologies, 2005-2013Posted in Windows  .NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Followup: Python 2.6, 3 abstract base class misunderstanding

    - by Aaron
    I asked a question at Python 2.6, 3 abstract base class misunderstanding. My problem was that python abstract base classes didn't work quite the way I expected them to. There was some discussion in the comments about why I would want to use ABCs at all, and Alex Martelli provided an excellent answer on why my use didn't work and how to accomplish what I wanted. Here I'd like to address why one might want to use ABCs, and show my test code implementation based on Alex's answer. tl;dr: Code after the 16th paragraph. In the discussion on the original post, statements were made along the lines that you don't need ABCs in Python, and that ABCs don't do anything and are therefore not real classes; they're merely interface definitions. An abstract base class is just a tool in your tool box. It's a design tool that's been around for many years, and a programming tool that is explicitly available in many programming languages. It can be implemented manually in languages that don't provide it. An ABC is always a real class, even when it doesn't do anything but define an interface, because specifying the interface is what an ABC does. If that was all an ABC could do, that would be enough reason to have it in your toolbox, but in Python and some other languages they can do more. The basic reason to use an ABC is when you have a number of classes that all do the same thing (have the same interface) but do it differently, and you want to guarantee that that complete interface is implemented in all objects. A user of your classes can rely on the interface being completely implemented in all classes. You can maintain this guarantee manually. Over time you may succeed. Or you might forget something. Before Python had ABCs you could guarantee it semi-manually, by throwing NotImplementedError in all the base class's interface methods; you must implement these methods in derived classes. This is only a partial solution, because you can still instantiate such a base class. A more complete solution is to use ABCs as provided in Python 2.6 and above. Template methods and other wrinkles and patterns are ideas whose implementation can be made easier with full-citizen ABCs. Another idea in the comments was that Python doesn't need ABCs (understood as a class that only defines an interface) because it has multiple inheritance. The implied reference there seems to be Java and its single inheritance. In Java you "get around" single inheritance by inheriting from one or more interfaces. Java uses the word "interface" in two ways. A "Java interface" is a class with method signatures but no implementations. The methods are the interface's "interface" in the more general, non-Java sense of the word. Yes, Python has multiple inheritance, so you don't need Java-like "interfaces" (ABCs) merely to provide sets of interface methods to a class. But that's not the only reason in software development to use ABCs. Most generally, you use an ABC to specify an interface (set of methods) that will likely be implemented differently in different derived classes, yet that all derived classes must have. Additionally, there may be no sensible default implementation for the base class to provide. Finally, even an ABC with almost no interface is still useful. We use something like it when we have multiple except clauses for a try. Many exceptions have exactly the same interface, with only two differences: the exception's string value, and the actual class of the exception. In many exception clauses we use nothing about the exception except its class to decide what to do; catching one type of exception we do one thing, and another except clause catching a different exception does another thing. According to the exception module's doc page, BaseException is not intended to be derived by any user defined exceptions. If ABCs had been a first class Python concept from the beginning, it's easy to imagine BaseException being specified as an ABC. But enough of that. Here's some 2.6 code that demonstrates how to use ABCs, and how to specify a list-like ABC. Examples are run in ipython, which I like much better than the python shell for day to day work; I only wish it was available for python3. Your basic 2.6 ABC: from abc import ABCMeta, abstractmethod class Super(): __metaclass__ = ABCMeta @abstractmethod def method1(self): pass Test it (in ipython, python shell would be similar): In [2]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods method1 Notice the end of the last line, where the TypeError exception tells us that method1 has not been implemented ("abstract methods method1"). That was the method designated as @abstractmethod in the preceding code. Create a subclass that inherits Super, implement method1 in the subclass and you're done. My problem, which caused me to ask the original question, was how to specify an ABC that itself defines a list interface. My naive solution was to make an ABC as above, and in the inheritance parentheses say (list). My assumption was that the class would still be abstract (can't instantiate it), and would be a list. That was wrong; inheriting from list made the class concrete, despite the abstract bits in the class definition. Alex suggested inheriting from collections.MutableSequence, which is abstract (and so doesn't make the class concrete) and list-like. I used collections.Sequence, which is also abstract but has a shorter interface and so was quicker to implement. First, Super derived from Sequence, with nothing extra: from abc import abstractmethod from collections import Sequence class Super(Sequence): pass Test it: In [6]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods __getitem__, __len__ We can't instantiate it. A list-like full-citizen ABC; yea! Again, notice in the last line that TypeError tells us why we can't instantiate it: __getitem__ and __len__ are abstract methods. They come from collections.Sequence. But, I want a bunch of subclasses that all act like immutable lists (which collections.Sequence essentially is), and that have their own implementations of my added interface methods. In particular, I don't want to implement my own list code, Python already did that for me. So first, let's implement the missing Sequence methods, in terms of Python's list type, so that all subclasses act as lists (Sequences). First let's see the signatures of the missing abstract methods: In [12]: help(Sequence.__getitem__) Help on method __getitem__ in module _abcoll: __getitem__(self, index) unbound _abcoll.Sequence method (END) In [14]: help(Sequence.__len__) Help on method __len__ in module _abcoll: __len__(self) unbound _abcoll.Sequence method (END) __getitem__ takes an index, and __len__ takes nothing. And the implementation (so far) is: from abc import abstractmethod from collections import Sequence class Super(Sequence): # Gives us a list member for ABC methods to use. def __init__(self): self._list = [] # Abstract method in Sequence, implemented in terms of list. def __getitem__(self, index): return self._list.__getitem__(index) # Abstract method in Sequence, implemented in terms of list. def __len__(self): return self._list.__len__() # Not required. Makes printing behave like a list. def __repr__(self): return self._list.__repr__() Test it: In [34]: a = Super() In [35]: a Out[35]: [] In [36]: print a [] In [37]: len(a) Out[37]: 0 In [38]: a[0] --------------------------------------------------------------------------- IndexError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() /home/aaron/projects/test/test.py in __getitem__(self, index) 10 # Abstract method in Sequence, implemented in terms of list. 11 def __getitem__(self, index): ---> 12 return self._list.__getitem__(index) 13 14 # Abstract method in Sequence, implemented in terms of list. IndexError: list index out of range Just like a list. It's not abstract (for the moment) because we implemented both of Sequence's abstract methods. Now I want to add my bit of interface, which will be abstract in Super and therefore required to implement in any subclasses. And we'll cut to the chase and add subclasses that inherit from our ABC Super. from abc import abstractmethod from collections import Sequence class Super(Sequence): # Gives us a list member for ABC methods to use. def __init__(self): self._list = [] # Abstract method in Sequence, implemented in terms of list. def __getitem__(self, index): return self._list.__getitem__(index) # Abstract method in Sequence, implemented in terms of list. def __len__(self): return self._list.__len__() # Not required. Makes printing behave like a list. def __repr__(self): return self._list.__repr__() @abstractmethod def method1(): pass class Sub0(Super): pass class Sub1(Super): def __init__(self): self._list = [1, 2, 3] def method1(self): return [x**2 for x in self._list] def method2(self): return [x/2.0 for x in self._list] class Sub2(Super): def __init__(self): self._list = [10, 20, 30, 40] def method1(self): return [x+2 for x in self._list] We've added a new abstract method to Super, method1. This makes Super abstract again. A new class Sub0 which inherits from Super but does not implement method1, so it's also an ABC. Two new classes Sub1 and Sub2, which both inherit from Super. They both implement method1 from Super, so they're not abstract. Both implementations of method1 are different. Sub1 and Sub2 also both initialize themselves differently; in real life they might initialize themselves wildly differently. So you have two subclasses which both "is a" Super (they both implement Super's required interface) although their implementations are different. Also remember that Super, although an ABC, provides four non-abstract methods. So Super provides two things to subclasses: an implementation of collections.Sequence, and an additional abstract interface (the one abstract method) that subclasses must implement. Also, class Sub1 implements an additional method, method2, which is not part of Super's interface. Sub1 "is a" Super, but it also has additional capabilities. Test it: In [52]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods method1 In [53]: a = Sub0() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Sub0 with abstract methods method1 In [54]: a = Sub1() In [55]: a Out[55]: [1, 2, 3] In [56]: b = Sub2() In [57]: b Out[57]: [10, 20, 30, 40] In [58]: print a, b [1, 2, 3] [10, 20, 30, 40] In [59]: a, b Out[59]: ([1, 2, 3], [10, 20, 30, 40]) In [60]: a.method1() Out[60]: [1, 4, 9] In [61]: b.method1() Out[61]: [12, 22, 32, 42] In [62]: a.method2() Out[62]: [0.5, 1.0, 1.5] [63]: a[:2] Out[63]: [1, 2] In [64]: a[0] = 5 --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: 'Sub1' object does not support item assignment Super and Sub0 are abstract and can't be instantiated (lines 52 and 53). Sub1 and Sub2 are concrete and have an immutable Sequence interface (54 through 59). Sub1 and Sub2 are instantiated differently, and their method1 implementations are different (60, 61). Sub1 includes an additional method2, beyond what's required by Super (62). Any concrete Super acts like a list/Sequence (63). A collections.Sequence is immutable (64). Finally, a wart: In [65]: a._list Out[65]: [1, 2, 3] In [66]: a._list = [] In [67]: a Out[67]: [] Super._list is spelled with a single underscore. Double underscore would have protected it from this last bit, but would have broken the implementation of methods in subclasses. Not sure why; I think because double underscore is private, and private means private. So ultimately this whole scheme relies on a gentleman's agreement not to reach in and muck with Super._list directly, as in line 65 above. Would love to know if there's a safer way to do that.

  • ASP.NET MVC 3 Hosting :: Rolling with Razor in MVC v3 Preview

    - by mbridge
    Razor is an alternate view engine for asp.net MVC.  It was introduced in the “WebMatrix” tool and has now been released as part of the asp.net MVC 3 preview 1.  Basically, Razor allows us to replace the clunky <% %> syntax with a much cleaner coding model, which integrates very nicely with HTML.  Additionally, it provides some really nice features for master page type scenarios and you don’t lose access to any of the features you are currently familiar with, such as HTML helper methods. First, download and install the ASP.NET MVC Preview 1.  You can find this at http://www.microsoft.com/downloads/details.aspx?FamilyID=cb42f741-8fb1-4f43-a5fa-812096f8d1e8&displaylang=en. Now, follow these steps to create your first asp.net mvc project using Razor: 1. Open Visual Studio 2010 2. Create a new project.  Select File->New->Project (Shift Control N) 3. You will see the list of project types which should look similar to what’s shown:   4. Select “ASP.NET MVC 3 Web Application (Razor).”  Set the application name to RazorTest and the path to c:projectsRazorTest for this tutorial. If you select accidently select ASPX, you will end up with the standard asp.net view engine and template, which isn’t what you want. 5. For this tutorial, and ONLY for this tutorial, select “No, do not create a unit test project.”  In general, you should create and use a unit test project.  Code without unit tests is kind of like diet ice cream.  It just isn’t very good. Now, once we have this done, our brand new project will be created.    In all likelihood, Visual Studio will leave you looking at the “HomeController.cs” class, as shown below: Immediately, you should notice one difference.  The Index action used to look like: public ActionResult Index () { ViewData[“Message”] = “Welcome to ASP.Net MVC!”; Return View(); } While this will still compile and run just fine, ASP.Net MVC 3 has a much nicer way of doing this: public ActionResult Index() { ViewModel.Message = “Welcome to ASP.Net MVC!”; Return View(); } Instead of using ViewData we are using the new ViewModel object, which uses the new dynamic data typing of .Net 4.0 to allow us to express ourselves much more cleanly.  This isn’t a tutorial on ALL of MVC 3, but the ViewModel concept is one we will need as we dig into Razor. What comes in the box? When we create a project using the ASP.Net MVC 3 Template with Razor, we get a standard project setup, just like we did in ASP.NET MVC 2.0 but with some differences.  Instead of seeing “.aspx” view files and “.ascx” files, we see files with the “.cshtml” which is the default razor extension.  Before we discuss the details of a razor file, one thing to keep in mind is that since this is an extremely early preview, intellisense is not currently enabled with the razor view engine.  This is promised as an updated before the final release.  Just like with the aspx view engine, the convention of the folder name for a set of views matching the controller name without the word “Controller” still stands.  Similarly, each action in the controller will usually have a corresponding view file in the appropriate view directory.  Remember, in asp.net MVC, convention over configuration is key to successful development! The initial template organizes views in the following folders, located in the project under Views: - Account – The default account management views used by the Account controller.  Each file represents a distinct view. - Home – Views corresponding to the appropriate actions within the home controller. - Shared – This contains common view objects used by multiple views.  Within here, master pages are stored, as well as partial page views (user controls).  By convention, these partial views are named “_XXXPartial.cshtml” where XXX is the appropriate name, such as _LogonPartial.cshtml.  Additionally, display templates are stored under here. With this in mind, let us take a look at the index.cshtml file under the home view directory.  When you open up index.cshtml you should see 1:   @inherits System.Web.Mvc.WebViewPage 2:  @{ 3:          View.Title = "Home Page"; 4:       LayoutPage = "~/Views/Shared/_Layout.cshtml"; 5:   } 6:  <h2>@View.Message</h2> 7:  <p> 8:     To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC     9:    Website">http://asp.net/mvc</a>. 10:  </p> So looking through this, we observe the following facts: Line 1 imports the base page that all views (using Razor) are based on, which is System.Web.Mvc.WebViewPage.  Note that this is different than System.Web.MVC.ViewPage which is used by asp.net MVC 2.0 Also note that instead of the <% %> syntax, we use the very simple ‘@’ sign.  The View Engine contains enough context sensitive logic that it can even distinguish between @ in code and @ in an email.  It’s a very clean markup.  Line 2 introduces the idea of a code block in razor.  A code block is a scoping mechanism just like it is in a normal C# class.  It is designated by @{… }  and any C# code can be placed in between.  Note that this is all server side code just like it is when using the aspx engine and <% %>.  Line 3 allows us to set the page title in the client page’s file.  This is a new feature which I’ll talk more about when we get to master pages, but it is another of the nice things razor brings to asp.net mvc development. Line 4 is where we specify our “master” page, but as you can see, you can place it almost anywhere you want, because you tell it where it is located.  A Layout Page is similar to a master page, but it gains a bit when it comes to flexibility.  Again, we’ll come back to this in a later installment.  Line 6 and beyond is where we display the contents of our view.  No more using <%: %> intermixed with code.  Instead, we get to use very clean syntax such as @View.Message.  This is a lot easier to read than <%:@View.Message%> especially when intermixed with html.  For example: <p> My name is @View.Name and I live at @View.Address </p> Compare this to the equivalent using the aspx view engine <p> My name is <%:View.Name %> and I live at <%: View.Address %> </p> While not an earth shaking simplification, it is easier on the eyes.  As  we explore other features, this clean markup will become more and more valuable.

  • Documenting C# Library using GhostDoc and SandCastle

    Documentation is an essential part of any IT project, especially when you are creating reusable components that will be used by other developers (such as class libraries). Without documentation re-using a class library is almost impossible. Just think of coding .net applications without MSDN documentation (Ooops I can’t think of it). Normally developers, who know the bits and pieces of their classes, see this as a boring work to write details again to generate the documentation. Also the amount of work to make this and manage it changes made the process of manual creation of Documentation impossible or tedious. So what is the effective solution? Let me divide this into two steps 1. Generate comments for your code while you are writing the code. 2. Create documentation file using these comments. Now I am going to examine these processes. Step 1: Generate XML Comments automatically Most of the developers write comments for their code. The best thing is that the comments will be entered during the development process. Additionally comments give a good reference to the code, make your code more manageable/readable. Later these comments can be converted into documentation, along with your source code by identifying properties and methods I found an add-in for visual studio, GhostDoc that automatically generates XML documentation comments for C#. The add-in is available in Visual Studio Gallery at MSDN. You can download this from the url http://visualstudiogallery.msdn.microsoft.com/en-us/46A20578-F0D5-4B1E-B55D-F001A6345748. I downloaded the free version from the above url. The free version suits my requirement. There is a professional version (you need to pay some $ for this) available that gives you some more features. I found the free version itself suits my requirements. The installation process is straight forward. A couple of clicks will do the work for you. The best thing with GhostDoc is that it supports multiple versions of visual studio such as 2005, 2008 and 2010. After Installing GhostDoc, when you start Visual studio, the GhostDoc configuration dialog will appear. The first screen asks you to assign a hot key, pressing this hotkey will enter the comment to your code file with the necessary structure required by GhostDoc. Click Assign to go to the next step where you configure the rules for generating the documentation from the code file. Click Create to start creating the rules. Click finish button to close this wizard. Now you performed the necessary configuration required by GhostDoc. Now In Visual Studio tools menu you can find the GhostDoc that gives you some options. Now let us examine how GhostDoc generate comments for a method. I have write the below code in my code behind file. public Char GetChar(string str, int pos) { return str[pos]; } Now I need to generate the comments for this function. Select the function and enter the hot key assigned during the configuration. GhostDoc will generate the comments as follows. /// <summary> /// Gets the char. /// </summary> /// <param name="str">The STR.</param> /// <param name="pos">The pos.</param> /// <returns></returns> public Char GetChar(string str, int pos) { return str[pos]; } So this is a very handy tool that helps developers writing comments easily. You can generate the xml documentation file separately while compiling the project. This will be done by the C# compiler. You can enable the xml documentation creation option (checkbox) under Project properties -> Build tab. Now when you compile, the xml file will created under the bin folder. Step 2: Generate the documentation from the XML file Now you have generated the xml file documentation. Sandcastle is the tool from Microsoft that generates MSDN style documentation from the compiler produced XML file. The project is available in codeplex http://sandcastle.codeplex.com/. Download and install Sandcastle to your computer. Sandcastle is a command line tool that doesn’t have a rich GUI. If you want to automate the documentation generation, definitely you will be using the command line tools. Since I want to generate the documentation from the xml file generated in the previous step, I was expecting a GUI where I can see the options. There is a GUI available for Sandcastle called Sandcastle Help File Builder. See the link to the project in codeplex. http://www.codeplex.com/wikipage?ProjectName=SHFB. You need to install Sandcastle and then the Sandcastle Help file builder. From here I assume that you have installed both sandcastle and Sandcastle help file builder successfully. Once you installed the help file builder, it will be available in your all programs list. Click on the Sandcastle Help File Builder GUI, will launch application. First you need to create a project. Click on File -> New project The New project dialog will appear. Choose a folder to store your project file and give a name for your documentation project. Click the save button. Now you will see your project properties. Now from the Project explorer, right click on the Documentation Sources, Click on the Add Documentation Source link. A documentation source is a file such as an assembly or a Visual Studio solution or project from which information will be extracted to produce API documentation. From the Add Documentation source dialog, I have selected the XML file generated by my project. Once you add the xml file to the project, you will see the dll file automatically added by the help file builder. Now click on the build button. Now the application will generate the help file. The Build window gives to the result of each steps. Once the process completed successfully, you will have the following output in the build window. Now navigate to your Help Project (I have selected the folder My Documents\Documentation), inside help folder, you can find the chm file. Open the chm file will give you MSDN like documentation. Documentation is an important part of development life cycle. Sandcastle with GhostDoc make this process easier so that developers can implement the documentation in the projects with simple to use steps.

  • FTP Publishing with the new Windows Azure Release

    - by Harish Ranganathan
    There is a good chance you might have stumbled upon the new Windows Azure Release that we made on June 6th.  Scott Guthrie’s Post quite summarizes the overall new features. One of my favorite features is the Windows Azure Websites and the ability to do publish files to Azure using your FTP Client. Windows Azure Websites offers low cost (free upto 10 websites) web hosting where you can deploy any website that can run on IIS 7.0, quickly. The earlier releases of Azure SDKs and the Azure platform support .NET 3.5 & above for running your applications.  This was a constraint for many since there are/were a lot of ASP.NET 2.0 applications built over time and simply to put it on Azure, many of you were skeptical to migrate it to .NET 4. Windows Azure Websites offer the flexibility of running IIS 7.0 supported .NET Versions which means you can run .NET 1.1, 2.0, 3.5 and .NET 4.  Not just that! You can also run classic ASP Applications. Windows Azure Websites don’t need you to go through the complexity of adding the Cloud Project Template and then publishing the Configuration Files.  Lets take a step by step understanding of Websites and publishing using FTP. I downloaded the Club Website Starter Kit from http://www.asp.net/downloads/starter-kits/club It also requires a database and I downloaded the SQL Scripts and created a SQL Server Database called Club. This installs a Web Site Project Template.  Note that I am running Windows 8 Release Preview and Visual Studio 2012 RC.  After installing the template, select File – New – Website and don’t forget to choose the Framework version as .NET 2.0 You can see the “Club Website Starter Kit” .  Once you select the Website gets created.  You would encounter a warning indicating that the Club Website Starter Kit uses SQL Express and the recommended database is LocalDB Express.  Click ok to continue.  Once the Website is created open up the Web.config and locate the “ClubSiteDB” connection string.  By default, it points to a SQL Express Database.  Instead configure it to use your local SQL Server. Also, open up Global.asax and comment out the following line if (!Roles.RoleExists("Administrators")) Roles.CreateRole("Administrators"); There seems to be an issue in the code that doesn’t create the role.  Post that, hit CTRL+F5 and you should be able to see the Website Running, as below So, now we have the Club Starter Kit site up running locally.  Moving to Azure Visit http://manage.windowsazure.com/ and sign up for a trial account.  This allows you to host up to 10 websites for free and a host of other benefits.  The free Websites can be extended to an year without any charge.  Once you have signed up, sign in to the portal using the Live ID used for sign up. After signing in, you would be presented with the “All Items” listing page which lists, Websites, Cloud Services, Databases etc.,  If this is the first time, you wouldn’t find anything. Click on the “Websites” link from the left menu.  Click on “New” in the bottom and it should show up a dialog.  In the same, select Website and click on “Quick Create” and in the URL Textbox, specify “MyFirstDemo” and click the “Create Web Site” link below. It should take a few seconds to create the Website.  Once the Website is created, click on the listing and it should open up the Dashboard.  Since we haven’t done anything yet, there shouldn’t be any statistics Click on the “Download publish profile” link in the right bottom.  This file has the FTP publishing settings. Also, if you scroll down you can see the FTP URL for this site.  It should typically start ftp://waws-xxxx-xxx-xxxx In the downloaded publish profile file, you can also find the ftp URL.  Pick the following from this file publishUrl (the 2nd one, the one that features after publishMethod =”FTP”) and the userName and userPWD that follows. Note that we have everything required to publish the files.  But since the Club Starter Kit uses Databases, we need to have the Database running on SQL Azure.  Go back to the Main Menu and click on “New” in the bottom but this time select “SQL Database” and provide “Club” as Database name for “Quick Create” If this is the first time a Server would be created.  Otherwise, it would pickup the existing server name. Once the database is created, you can use the SQL Azure Migration Wizard http://sqlazuremw.codeplex.com/ and provide the credentials to connect to local database and then the SQL Azure database for migrating the “Club” database.  The migration wizard UI hasn’t changed much and is the same as explained by me in one my posts earlier http://geekswithblogs.net/ranganh/archive/2009/09/29/taking-your-northwind-database-to-sql-azure-and-binding-it.aspx Once the database is migrated, come back to the main screen and click on the Database base in the Azure Management Portal.  It opens up the dashboard of the database.  Click on “Show connection Strings” and it would popup a list of connection string formats.  Choose the ADO.NET connection string and after editing the password with the password that you provided when creating the database server in the Azure Portal, paste it into the config file of the Club Starter Kit Website.  Just to reiterate, the connection string key is ClubSiteDB. Try running the Website once to ensure that the application though running locally could connect to the SQL Database running on Azure. Once you are able to run the website successfully, we are all set to do the FTP Publishing. Download your favorite FTP tool.  I use http://filezilla-project.org/ In the Host Textbox, paste the FTP URL that you picked up from the publish profile file and also paste the username and password.  Click on “QuickConnect”.  If everything is fine, you should be able to connect to the remote server.  If it is successfully connected, you can see the wwwroot folder of the Website, running in Azure Make sure on the “Local Site” in the left, you choose the path to the folder of your Website.  Open up the Website folder on the left such that it lists all the files and folders inside.  Select all of them and click select “Upload” or simply drag and drop all the files to the root folder that is listed above.  Once the publishing is done, you should be able to hit the SiteURL that you can find the dashboard page of the website.  In our case, it would be http://MyFirstDemo.azurewebsites.net That’s it, we have now done FTP publishing in Azure and that too we are running a .NET 2.0 Website on Azure. Cheers !!!

  • class hierarchy design for small java project

    - by user523956
    I have written a java code which does following:- Main goal is to fetch emails from (inbox, spam) folders and store them in database. It fetches emails from gmail,gmx,web.de,yahoo and Hotmail. Following attributes are stored in mysql database. Slno, messagedigest, messageid, foldername, dateandtime, receiver, sender, subject, cc, size and emlfile. For gmail,gmy and web.de, I have used javamail API, because email form it can be fetched with IMAP. For yahoo and hotmail, I have used html parser and httpclient to fetch emails form spam folder and for inbox folder, I have used pop3 javamail API. I want to have proper class hierarchy which makes my code efficient and easily reusable. As of now I have designed class hierarchy as below: I am sure it can still be improved. So I would like to have different opinions on it. I have following classes and methods as of now. MainController:- Here I pass emailid, password and foldername from which emails have to be fetched. Abstract Class :-EmailProtocol Abstract Methods of it (All methods except executeParser contains method definition):- connectImap() // used by gmx,gmail and web.de email ids connectPop3() // used by hotmail and yahoo to fetch emails of inbox folder createMessageDigest // used by every email provider(gmx, gmail,web.de,yahoo,hotmail) establishDBConnection // used by every email emailAlreadyExists // used by every email which checks whether email already exists in db or not, if not then store it. storeemailproperties // used by every email to store emails properties to mysql database executeParser // nothing written in it. Overwridden and used by just hotmail and yahoo to fetch emails form spam folder. Imap extends EmailProtocol (nothing in it. But I have to have it to access methods of EmailProtocol. This is used to fetch emails from gmail,gmx and web.de) I know this is really a bad way but don't know how to do it other way. Hotmsil extends EmailProtocol Methods:- executeParser() :- This is used by just hotmail email id. fetchjunkemails() :- This is also very specific for only hotmail email id. Yahoo extends EmailProtocol Methods:- executeParser() storeEmailtotemptable() MoveEmailtoInbox() getFoldername() nullorEquals() All above methods are specific for yahoo email id. public DateTimeFormat(class) format() //this formats datetime of gmax,gmail and web.de emails. formatYahoodate //this formats datetime of yahoo email. formatHotmaildate // this formats datetime of hotmail email. public StringFormat ConvertStreamToString() // Accessed by every class except DateTimeFormat class. formatFromTo() // Accessed by every class except DateTimeFormat class. public Class CheckDatabaseExistance public static void checkForDatabaseTablesAvailability() (This method checks at the beginnning whether database and required tables exist in mysql or not. if not it creates them) Please see code of my MainController class so that You can have an idea about how I use different classes. public class MainController { public static void main(String[] args) throws Exception { ArrayList<String> web_de_folders = new ArrayList<String>(); web_de_folders.add("INBOX"); web_de_folders.add("Unbekannt"); web_de_folders.add("Spam"); web_de_folders.add("OUTBOX"); web_de_folders.add("SENT"); web_de_folders.add("DRAFTS"); web_de_folders.add("TRASH"); web_de_folders.add("Trash"); ArrayList<String> gmx_folders = new ArrayList<String>(); gmx_folders.add("INBOX"); gmx_folders.add("Archiv"); gmx_folders.add("Entwürfe"); gmx_folders.add("Gelöscht"); gmx_folders.add("Gesendet"); gmx_folders.add("Spamverdacht"); gmx_folders.add("Trash"); ArrayList<String> gmail_folders = new ArrayList<String>(); gmail_folders.add("Inbox"); gmail_folders.add("[Google Mail]/Spam"); gmail_folders.add("[Google Mail]/Trash"); gmail_folders.add("[Google Mail]/Sent Mail"); ArrayList<String> pop3_folders = new ArrayList<String>(); pop3_folders.add("INBOX"); CheckDatabaseExistance.checkForDatabaseTablesAvailability(); EmailProtocol imap = new Imap(); System.out.println("CHECKING FOR NEW EMAILS IN WEB.DE...(IMAP)"); System.out.println("*********************************************************************************"); imap.connectImap("[email protected]", "pwd", web_de_folders); System.out.println("\nCHECKING FOR NEW EMAILS IN GMX.DE...(IMAP)"); System.out.println("*********************************************************************************"); imap.connectImap("[email protected]", "pwd", gmx_folders); System.out.println("\nCHECKING FOR NEW EMAILS IN GMAIL...(IMAP)"); System.out.println("*********************************************************************************"); imap.connectImap("[email protected]", "pwd", gmail_folders); EmailProtocol yahoo = new Yahoo(); Yahoo y=new Yahoo(); System.out.println("\nEXECUTING YAHOO PARSER"); System.out.println("*********************************************************************************"); y.executeParser("http://de.mc1321.mail.yahoo.com/mc/welcome?ymv=0","[email protected]","pwd"); System.out.println("\nCHECKING FOR NEW EMAILS IN INBOX OF YAHOO (POP3)"); System.out.println("*********************************************************************************"); yahoo.connectPop3("[email protected]","pwd",pop3_folders); System.out.println("\nCHECKING FOR NEW EMAILS IN INBOX OF HOTMAIL (POP3)"); System.out.println("*********************************************************************************"); yahoo.connectPop3("[email protected]","pwd",pop3_folders); EmailProtocol hotmail = new Hotmail(); Hotmail h=new Hotmail(); System.out.println("\nEXECUTING HOTMAIL PARSER"); System.out.println("*********************************************************************************"); h.executeParser("https://login.live.com/ppsecure/post.srf","[email protected]","pwd"); } } I have kept DatetimeFormat and StringFormat class public so that I can access its public methods by just (DatetimeFormat.formatYahoodate for e.g. from different methods). This is the first time I have developed something in java. It serves its purpose but of course code is still not so efficient I think. I need your suggestions on this project.
