• Actionscript: How Can I Know When The Source Property Of An Image Is Completely Updated

  - by Joshua

  var I:Image=new Image(); I.source='C:\\Abc.png'; var H:int=I.height; H is always Zero! I am presuming this is because the image hasn't finished reading the png file off the disk yet. What event can I monitor to know when it's width and height will have the right values? The 'Complete' event only seems to work for DOWNLOADED images. The 'Render' event happens EVERY FRAME. The (undocumented?) 'sourceChanged', happens as soon as source changes, and has the same problem! What event do I watch that will let me know when the image's width and height properties will have valid values? Or is there some Synchronous version of I.source='xxx.png', that I don't know about? P.S. Yes, I know I shouldn't use "C:\" in an Air Program. This was just for illustrative purposes, so that you won't suggest I use "Complete", which never even seems to fire when the file indicated by source is local.

• Android: Associating Browser to File Type in App

  - by tekmunki

  I'm attempting to write a simple app that associates a file type to the browser; this is assuming the browser will open the file locally... If this doesn't work, the local file - editor will be fine. I have an option of auto-mailing .ELC files from a custom app, they are basically html formatted TEXT or TXT only files; I would like to associate the .elc extension so that it will open direct from mail rather than just "Save to SD Card" as a mail option. Here's the code I'm at right now; AndroidManifest.xml: ELCViewer.java: package com.tekmunki.ELCViewer; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class ELCViewer extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("ELC Viewer Installed! Now, when you receive the ELC files, they will open in the browser."); setContentView(tv); } } 1) How do I make the browser associated with the ELCViewer Activity? (Do I need to make a second activity, or can that all be done in the manifest?) 2) How do I make it persist after the app has been ran once?

• Importing package as a submodule

  - by wecac

  Hi, I have a package 3rd party open source package "foo"; that is in beta phase and I want to tweak it to my requirements. So I don't want to get it installed in /usr/local/lib/python or anywhere in current sys.path as I can't make frequent changes in top level packages. foo/ __init__.py fmod1.py import foo.mod2 fmod2.py pass I want to install the the package "foo" as a sub package of my namespace say "team.my_pkg". So that the "fullname" of the package becomes "team.my_pkg.foo" without changing the code in inner modules that refer "team.my_pkg.foo" as "foo". team/ __init__.py my_pkg/ __init__.py foo/ fmod1.py import foo.mod2 fmod2.py pass One way to do this is to do this in team.my_pkg.init.py: import os.path import sys sys.path.append(os.path.dirname(__file__)) But I think it is very unsafe. I hope there is some way that only fmod1.py and fmod2.py can call "foo" by its short name everything else should use its complete name "team.my_pkg.foo" I mean this should fail outside team/my_pkg/foo: import team.my_pkg import foo But this should succeed outside team/my_pkg/foo: import team.my_pkg.foo

• Where to store: User connection information?

  - by TomTom

  ;) I am writing a .NET application wher ethe user connects to a given server. ALl information within the application is stored in the server. But I want / need to store the following information for the user: The server he connected to last The username he used to connect last (and no, no password, never ever). Any idea where to store this best? the application config file is not sensible (user != admin, application.config is write protected for him). So, my options are: In the registry. 2 keys under my own subkey. In a sort of ini file, stored in the user's data directory (AppData). This would possibly also allow later expansion (into like saving more information, some of which may not fit into the registry). Anyone a tip? Other alternatives? I tend so far to go for the AppData directory with my own subfolder - simply because it is a nice preparation for later to keep like a local copy of configuration etc.

• RegEx expression or jQuery selector to NOT match "external" links in href

  - by TrueBlueAussie

  I have a jQuery plugin that overrides link behavior, to allow Ajax loading of page content. Simple enough with a delegated event like $(document).on('click','a', function(){});. but I only want it to apply to links that are not like these ones (Ajax loading is not applicable to them, so links like these need to behave normally): target="_blank" // New browser window href="#..." // Bookmark link (page is already loaded). href="afs://..." // AFS file access. href="cid://..." // Content identifiers for MIME body part. href="file://..." // Specifies the address of a file from the locally accessible drive. href="ftp://..." // Uses Internet File Transfer Protocol (FTP) to retrieve a file. href="http://..." // The most commonly used access method. href="https://..." // Provide some level of security of transmission href="mailto://..." // Opens an email program. href="mid://..." // The message identifier for email. href="news://..." // Usenet newsgroup. href="x-exec://..." // Executable program. href="http://AnythingNotHere.com" // External links Sample code: $(document).on('click', 'a:not([target="_blank"])', function(){ var $this = $(this); if ('some additional check of href'){ // Do ajax load and stop default behaviour return false; } // allow link to work normally }); Q: Is there a way to easily detect all "local links" that would only navigate within the current website? excluding all the variations mentioned above. Note: This is for an MVC 5 Razor website, so absolute site URLs are unlikely to occur.

• Perl 500 internal server error. Something wrong with my code.

  - by Nitish

  I get a 500 internal server error when I try to run the code below in a web server which supports perl: #! /usr/bin/perl use LWP; my $ua = LWP::UserAgent->new; $ua->agent("TestApp/0.1 "); $ua->env_proxy(); my $req = HTTP::Request->new(POST => 'http://www.google.com/loc/json'); $req->content_type('application/jsonrequest'); $req->content('{ "cell_towers": [{"location_area_code": "55000", "mobile_network_code": "95", "cell_id": "20491", "mobile_country_code": "404"}], "version": "1.1.0", "request_address": "true"}'); my $res = $ua->request($req); if ($res->is_success) { print $res->content,"\n"; } else { print $res->status_line, "\n"; return undef; } But there is no error when I run the code below: #! /usr/bin/perl use CGI::Carp qw(fatalsToBrowser); print "Content-type: text/html\n\n"; print "<HTML>\n"; print "<HEAD><TITLE>Hello World!</TITLE></HEAD>\n"; print "<BODY>\n"; print "<H2>Hello World!</H2> <br /> \n"; foreach $key (sort keys(%ENV)) { print "$key = $ENV{$key}<p>" ; } print "</BODY>\n"; print "</HTML>\n"; So I think there is some problem with my code. When I run the first perl script in my local machine with the -wc command, it says that the syntax is OK. Help me please.

• nservicebus deleting subscription record after inserting it?

  - by Justin Holbrook

  I have been playing with nservicebus for a few weeks now and since everything was going well on my local machine I decided to try to set up a test environment and work on deployment. I am using the generic host that comes with nservicebus and was using the nservicebus.Integration profile when running locally, but would like to use Nservicebus.Production in the test environment. I set up a sql server 2008 database, made changes to my app.config and everything seemed to work fine. But after a few attempts, I noticed messages were not being picked up by my subscriber. I checked the subscription table and it was empty. Upon examination of the logs I noticed the following: 2010-05-06 15:07:57,416 [1] DEBUG NHibernate.Persister.Entity.AbstractEntityPers ister [(null)] <(null) - Insert 0: INSERT INTO [Subscription] (SubscriberEndpo int, MessageType) VALUES (?, ?) 2010-05-06 15:07:57,416 [1] DEBUG NHibernate.Persister.Entity.AbstractEntityPers ister [(null)] <(null) - Update 0: 2010-05-06 15:07:57,416 [1] DEBUG NHibernate.Persister.Entity.AbstractEntityPers ister [(null)] <(null) - Delete 0: DELETE FROM [Subscription] WHERE Subscriber Endpoint = ? AND MessageType = ? Why would it insert then delete my subscription right afterwards? To try to rule out a nhibernate dialect issue I tried switching my subscription storage to an oracle 10g database. It behaved exactly the same, it worked the first 2 times, then I started seeing my subscriptions being deleted right after they were inserted. Any ideas what is causing this behavior?

• Migrating MachineKey from iis6 on old server to iis7 on new server

  - by MaseBase

  I am migrating our hosting environment to a totally new data center with new boxes and hardware and software... the whole deal. Our website cookies are encrypted using the machineKey, so when I make a request to my domain and point it to the new web server (by overriding the local hosts file), I get an error because the cookie cannot be decrypted, since the Machine Key is different. I'd like to avoid any problems a frequent user might have when they arrive at the new server for the first time. To the best of my knowledge, at this point I think I need to set the same MachineKey from our current servers on our new servers. This way when past visitors with a cookie arrive at our website served by the new server, the cookie will be decrypted properly with the MachineKey it was encrypted with and then log them in properly. My question is where do I find my MachineKey value (in IIS 6 win2k3 server) so I can use that value to set it statically on my new servers? I've pulled up my machine.config file, but it doesn't specify the key, it only specifies a configSection where the key can be defined. It's not in my web.config for the app or elsewhere. I did find this great article on some MachineKey and Web Garden woes (which could explain some other bugs I've been experiencing with regard to the machineKey). Update I am back to this issue and am still faced with a similar problem. I have the MachineKey auto-generated on the IIS6 server but I need to get that exact key so I can set it explicitly and not have it auto-generated anymore. Any help is appreciated...

• Coldfusion 8 and HTTP PUT - is there a way to PUT an object?

  - by ciaranarcher

  Hi all We are using EHCache with CF 8 to cache stuff on a central server using a RESTful interface over HTTP. I am trying to cache a cfquery object to the cache server. I can get this to work if I call EHCache direct (i.e. store it in a local cache) but if I try to cache on a remote server over HTTP I am running into problems. The code I am using is as follows: <cfhttp url="http://localhost:8080/myCache/myKey" method="put" result="r" timeout="2" throwonerror="true" > <cfhttpparam type="body" value="#ARGUMENTS.item#" /> </cfhttp> CF doesn't like this reference to #ARGUMENTS.item# and it complains Complex object types cannot be converted to simple values. Can anyone give me an example of how to put an object over http using CF? If this is not possible with CF then a Java example would be the next best thing. Many thanks in advance! PS: I do not want to use serialization to text/JSON etc. as this approach has issues with data integrity and most importantly it's not fast enough.

• In need of a Smarter Environmental Package Configuration

  - by Jeremy Liberman

  I am trying to set up a package template in SSIS, following the Wrox Programmer to Programmer book, SQL Server 2008 Integration Services: Problem - Design - Solution. I'm really liking this book even though it is 2008 and we're using SQL Server 2005. I've got a working package template that uses an Indirect XML package configuration to identify what environment (local developer, dev, QA, production, etc) the package is being run in. That locates the SQL Server package configuration for the environment. That set-up is great and all except for the environment variable at the very front of it all. My team would prefer it if the package could use the same environment resource locator as all our other applications and tools use, so we don't two environment markers with essentially the same information in them. Normally we look up a registry key in HKey_Local_Machine but the Registry Package Configuration type only lets you look up the HKey_Current_User registries. My first thought was to write a new Package Configuration Type class that extends the Registry type; after all we'd had such luck writing our own custom log provider. SSIS is super extendable, right? So there doesn't seem to be a way to write your own Package Configuration Types. Is there still some way I can configure my SSIS SQL Server package configuration from a HKLM registry key connection string? If this is not possible, what other workarounds are available? My idea is to write a PowerShell script that will create/modify the Environment Variable that the package will use by fetching the connection string from the registry. This way there's still two markers, but at least then it's automatically maintained and automated. Is this kind of workaround necessary? Thank you for your time.

• Executing a process in windows server 2003 and ii6 from code - permissions error

  - by kurupt_89

  I have a problem executing a process from our testing server. On my localhost using windows XP and iis5.1 I changed the machine.config file to have the line - I then changed the login for iis to log on as local system account and allow server to interact with desktop. This fixed my problem executing a process from code in xp. When using the same method on windows server 2003 (using iis6 isolation mode) the process does not get executed. Here is the code to execute the process (I have tested the inputs to iecapt through the command line and an image is generated) - public static void GenerateImageToDisk(string ieCaptPath, string url, string path, int delay) { url = FixUrl(url); ieCaptPath = FixPath(ieCaptPath); string arguments = @"--url=""{0}"" --out=""{1}"" --min-width=0 --delay={2}"; arguments = string.Format(arguments, url, path, delay); ProcessStartInfo ieCaptProcessStartInfo = new ProcessStartInfo(ieCaptPath + "IECapt.exe"); ieCaptProcessStartInfo.RedirectStandardOutput = true; ieCaptProcessStartInfo.WindowStyle = ProcessWindowStyle.Hidden; ieCaptProcessStartInfo.UseShellExecute = false; ieCaptProcessStartInfo.Arguments = arguments; ieCaptProcessStartInfo.WorkingDirectory = ieCaptPath; Process ieCaptProcess = Process.Start(ieCaptProcessStartInfo); ieCaptProcess.WaitForExit(600000); ieCaptProcess.Close(); }

• Convert asp.net application to windows forms app

  - by rogdawg

  I have written and deployed an ASP.NET application that is pretty complex. It uses XSL transformations to create web forms for a large variety of data objects. The data comes from the database as XML via a web service. Now, I need to create a Windows desktop application that will provide a small subset of the web applications functionality to a user who may not have access to the web (working in remote areas). I will provide the data syncing using the MS Sync Framework. And I will have the desktop use a local data store. I would like to use the same xslt files in the desktop app that I use in the web app for the form creation so that, if changes are made, the desktop app can update itself when it connects and syncs its data. But, I am wondering how to replicate the asp.net codebehind logic of my web app in the windows forms. If I use a browser control to render the XSLTransformation result, then how could I handle click events, etc, in the form? Also, can I launch other windows as "dialog boxes" from my windows forms (I do this in my web app using RadControls functionality)? Thanks for any advice you can give.

• View Source and Chrome Developer Tools showing different output

  - by patricksweeney

  I have a page located here. Viewing it in Chrome and Firefox show a really small h1 title, and also it changes color as if it is a link. The template that generates everything looks exactly how it should be. When diagnosing the issue, the relevant section of code looks like this when I go to view source: <div class="page-heading"> <h1>Title Here</h1> </div> However, when I go to view it in Chrome's Developer tools, it is throwing in extraneous malformed anchor tags, which is obviously causing the hovering behavior. This is what it looks like to the dev tools: <div class="page-heading"> <h1> <a style="font-family: arial; font-size: 9px" <="" a="">Title Here</a> </h1> </div> In addition, when viewing a local copy of the site, the output shown in the dev tools is the same as viewing the source and they both render correctly locally. Oddly enough, all version of IE render it correctly. The current version of both Chrome and Firefox both render it weirdly. Initially I thought it may be a user agent stylesheet problem, but if anything the CSS is fine, it's the HTML that is malformed.

• FTP exception 501 "pathname" more than 8 characters

  - by BigMac66

  I am trying to access a file via a URI using the FTP protocol. For obvious security reasons I had to make some changes but this is where the problems seem to be coming from. My URI is as follows: ftp://user:[email protected]/u/Bigpathname/XYZ/ABC/BigPathname/bigpathname/xyz/abc/MY_LOG.LOG And I see this exception: sun.net.ftp.FtpProtocolException: CWD Bigpathname:501 A qualifier in "Bigpathname" is more than 8 characters This is really confusing as I can access the file from a Windows 7 command line with the CD command just fine. Both one directory at a time and as a full path. I found one article mentioning that MVS file names must be 8 or fewer characters but this does not explain how I can get to these same files from my command line! They do exist there is data there that I can download manual but I can not get there via a URI in Java. PS I use .toURL().openStream() to get files on my local machine just fine, it only fails when I try to get them from my server. EDIT October 1st I am able to access files on the MVS host using FileZilla and the basic FTP client from the Windows 7 command line - but I still cannot get them from a URI/URL. I downloaded a very basic Java built FTP client and tried accessing the same file in my program from there and the path works but because my file name has a dot in it "MY_LOG.LOG" I am getting File does not exist 501 Invalid data set name "MY_LOG.LOG". Use MVS Dsname conventions. I am utterly perplexed by this...

• Youtube Javascript API play(); not working.. what am I doing wrong?

  Hello, I'm playing around with YouTubes Javascript API. I've set up a test page on my local enviornment, but the play function is not working. The video loads, and I can press play on the yt video screen, but my link "play" isn't working. Can someone tell me what I'm doing wrong??

• Can g++ fill uninitialized POD variables with known values?

  - by Bob Lied

  I know that Visual Studio under debugging options will fill memory with a known value. Does g++ (any version, but gcc 4.1.2 is most interesting) have any options that would fill an uninitialized local POD structure with recognizable values? struct something{ int a; int b; }; void foo() { something uninitialized; bar(uninitialized.b); } I expect uninitialized.b to be unpredictable randomness; clearly a bug and easily found if optimization and warnings are turned on. But compiled with -g only, no warning. A colleague had a case where code similar to this worked because it coincidentally had a valid value; when the compiler upgraded, it started failing. He thought it was because the new compiler was inserting known values into the structure (much the way that VS fills 0xCC). In my own experience, it was just different random values that didn't happen to be valid. But now I'm curious -- is there any setting of g++ that would make it fill memory that the standard would otherwise say should be uninitialized?

• subversion: how to manage tweaked files

  - by punk4funk

  Our group is considering moving to SVN. But, I can't seem to find a way to do the following: I need to make minor tweaks locally to about 20 files in the repository w/o having SVN consider them "changed" and included in the commit. (Changes like communication time-outs and logging levels.) Ideally I would want to merge the tweaked files to newer versions in the repository. (Keeping the tweaked local file up-to-date with committed changes form other users.) I can't imagine we're unique in wanting/needing this. Are there best practices around this type of use case? One thing I'm considering is putting all the tweaked files into a branched "tweaked" working copy. Then merging my tweaked files into my "official" working copy. Then using a script, which compares the "tweaked" and "official" working copies, to update my ignore list. The script would also un-ignore and alert me to any files that had tweaks and other changes that, presumably, needed to be committed to the repository. This seems kinda hacky and I can't imagine there's not a better way.

• Which Perl moudle can handle variety of date formats with unicode characters ?

  - by ram

  My requirement is parsing xml files which contains wide varieties of timestamps based on the locales at which they are written. They may contain Unicode characters in case of Chinese or Korean locales. I have to parse these timestamps and put then in a standard format something like 2009-11-26 12:40:54 to put them in a oracle database. Sometimes I may not even know the locale and yet I have to parse the timestamps. I am looking for a module that automatically detects the timestamp format (including unicode characters for am and pm in their local language) and converts in to epoch time so that I can convert it back to what ever way I like to. I have gone through similar questions in this forum. Few suggested DateFormat module, and Date::Parse module. The perl distribution I am using is 5.10 so Date::Manip doesn't come as a core module. As I am supposed to use just the basic core modules and few CPAN modules(on request I cannot ask for all), I request you to kindly suggest me a good module that suffices all my requirements. Thanks in advance

• Subversion Partial Export

  - by Jared

  I have somewhat interesting development situation. The client and deployment server are inside a firewall without access to the Subversion server. But the developers are outside the firewall and are able to use the Subversion server. Right now the solution I have worked out is to update my local copy of the code and then pull out the most recently updated files using UnleashIT. The question is how to get just the updated files out of Subversion so that they can be physically transported through the firewall and put on the deployment server. I'm not worried about trying to change the firewall setup or trying to figure out an easier way to get to the Subversion server from inside the firewall. I'm just interested in a way to get a partial export from the repository of the most recently changed files. Are there any other suggestions? Answer found: In addition to the answer I marked as Answer, I've also found the following here to be able to do this from TortoiseSVN: from http://svn.haxx.se/tsvn/archive-2006-08/0051.shtml * select the two revisions * right-click, "compare revisions" * select all files in the list * right-click, choose "export to..."

• Combine MD5 hashes of multiple files

  - by user685869

  I have 7 files that I'm generating MD5 hashes for. The hashes are used to ensure that a remote copy of the data store is identical to the local copy. Unfortunately, the link between these two copies of the data is mind numbingly slow. Changes to the data are very rare but I have a requirement that the data be synchronized at all times (or as soon as possible). Rather than passing 7 different MD5 hashes across my (extremely slow) communications link, I'd like to generate the hash for each file and then combine these hashes into a single hash which I can then transfer and then re-calculate/use for comparison on the remote side. If the "combined hash" differs, then I'd start sending the 7 individual hashes to determine exactly which file(s) have been changed. For example, here are the MD5 hashes for the 7 files as of last week: 0709d609d69385255c496436eb50402c 709465a74411bd596595c7b9b158ae6a 4ab657320ef33e3d5eb498e4c13d41b7 3b49c6ab199994fd776bb63761414e72 0fc28c5a010fc3c06c0c930c88e31a15 c4ecd214662cac5aae0e53f6f252bf0e 8b086431e43148a2c2d943ba30d31cc6 I'd like to combine these hashes together such that I get a single unique value (perhaps another MD5 hash?) that I can then send to the remote system. On the remote system, I'd then perform the same calculation to determine if the data as a whole has been changed. If it has, then I'd start sending the individual hashes, etc. The most important factor is that my "combined hash" be short enough so that it uses less bandwidth than just sending all 7 hashes in the first place. I thought of writing the 7 MD5 hashes to a file and then hashing that file but is there a better way?

I wrote this function to get the timezone data for any city or address. function gettimezone($address) { $_url = 'http://api.local.yahoo.com/MapsService/V1/geocode'; $_url .= sprintf('?appid=%s&location=%s',"phpclasses",rawurlencode($address)); $_result = false; if($_result = file_get_contents($_url)) { preg_match('!<Latitude>(.*)</Latitude><Longitude>(.*)</Longitude>!U', $_result, $_match); $lng = $_match[2]; $lat = $_match[1]; $url = "http://ws.geonames.org/timezone?lat={$lat}&lng={$lng}"; $timedata = file_get_contents($url); $sxml = simplexml_load_string($timedata); return $sxml->timezone; } else return false; } I am working on Windows 7 and xampp 1.7 (php 5.2.8). Is there any possible scenario where this piece of code would crash Apache? The application runs fine almost everytime, but I think running this piece of code when there is no internet connectivity or very poor internet connectivity (thereby no access to either of the webservices I have used) brings down the server. Something like this happened a few times and I think it was due to loss of internet connectivity but I am not sure what exactly is going on. [ By the way, feel free to use this piece of code. Makes 2 web service calls so don't use to too often in your application. Consider storing the results in a database.]

• Strange compiler complaint when using similar code

  - by Jason

  For a project, I have to ask the user for a file name, and I'm reading it in character by character using getchar. From the main, I call the function char *coursename= introPrint(); //start off to print the usage directions and get the first bit of input. That function is defined as char *introPrint(){ int size= 20; int c; int length=0; char buffer[size]; //instructions printout, cut for brevity //get coursename from user and return it while ( (c=getchar()) != EOF && (c != '\n') ){ buffer[length++]= c; if (length==size-1) break; } buffer[length]=0; return buffer; } This is basically identical code I wrote to ask the user for input, replace the character echo with asterisks, then print out the results. Here, though, I'm getting a function returns address of local variable warning for the return statement. So why am I getting no warnings from the other program, but trigger one for this code?

• Looking for a good C++/.net

  - by Michael Minerva

  I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.
