• How can I deploy my .NET app to Amazon EC2?

  - by Khash

  I have a .NET Windows service and a .NET Web Application that I would like to deploy to my Amazon EC2 Windows 2008 instances. At this point, all I need to do is to copy the zipped files across to the EC2 box and remote desktop to the EC2 instance and finish the deployment. In order to do this, I have tried LogMeIn Hamachi2 to create a P2P VPN and use RoboCopy to copy the files, however it seems Hamachi doesn't work on Windows EC2. What is your solution for deploying your .NET apps to Windows EC2 instances? I want to avoid running an FTP server on the box just to get my files up on the server and don't have a VPN server (like OpenVPN) running to run a cloud based VPN solution. Perhaps I can find a simple way of using Amazon S3 as a strategy? Any ideas? Suggestions?

• Oracle vocabulary, what is the mysql/SQL Server equivalent of a database

  - by jeph perro

  Hi, I need some help with vocabulary, I don't use Oracle that often but I am familiar with MySQL and SQL Server. I have an application I need to upgrade and migrate, and part of the procedure to do that involves exporting to an XML file, allowing the installer to create new database tables, then import to the new database tables from the XML file. In Oracle, my database connection specifies a username, password, and an SID. Let's call the SID, "COMPANY-APPS". This SID contains tables belonging to several applications, each of which connects with a different user ( "WIKIUSER", "BUGUSER", "TIMETRACKERUSER" ). My question is: Can I re-use the same user to create the new tables ( with the same names ). In MySQL or SQL Server, I would create a new database and grant my user privileges to create tables in it. OR, do I need to create a new database user for my upgraded tables?

• Running your own GAE server

  - by h2g2java

  The question http://stackoverflow.com/questions/2505265/how-difficult-is-it-to-migrate-away-from-google-app-engine triggered me to think about this issue again. I have read of someone running, production-wise, Google app engine development version on their own server. My questions are: Are there any security issues running GAE development on your own server in production mode and exposing it to the www? If so how to mitigate them? Can GAE dev be run on Amazon? Is it possible to port my GAE apps running on Google servers to a GAE running on Amazon, without code changes, but without changing any reference in using other gdata services such as google docs, youtube, gmail, etc. How to configure GAE dev server to use my own hadoop? Or to use Amazon's hadoop?

• How to configure SQLite db in Visual Studio

  - by ChrisC

  I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

• Good Guide For Web App Security?

  - by QAH

  Hello! I am pretty good on making web applications and I know how to transfer data to and from client/server, etc. I need some help though learning how to make the data exchanges more secure. That is the reason why I feel kind of scared to publish any web app I make. I wanted to know what are some good guides to help you understand and learn how to secure data transfer with your web application? Things like better authentication for example and making better logins. You can post any suggestion, but just for your information, I mainly code my web apps with Javascript and PHP. Also, I transfer my data using JSON or XML. Thanks a lot

• MS Access 2003 - Help understanding the structure of mdb, mde and be.....

  - by Justin

  Hi. I was just wanting some explanation as to what is going on once you have split your tables out into a back end file, and set an mde out for use. When a user accesses the mde, is the mdb still required to get to the tabes (or in order to make it work)? Let say I put these access apps on a shared drive for folks to use. If I split the be end on to the shared drive, and placed the mde on the shared drive, would I the mdb have to exist for that version mde to work (communicate with the tables)? Or does the mde sort of speak to the mdb which speaks to the tables? Hope this question makes sense. Thanks

• Why can't we use a Translucent system bars with and ActionBar

  - by Waza_Be

  While updating my apps to Kitkat, I just wanted to give them a gorgeous look on KitKat using the Translucent property: Translucent system bars You can now make the system bars partially translucent with new themes, Theme.Holo.NoActionBar.TranslucentDecor and Theme.Holo.Light.NoActionBar.TranslucentDecor. By enabling translucent system bars, your layout will fill the area behind the system bars, so you must also enable [fitsSystemWindows][4] for the portion of your layout that should not be covered by the system bars. My only concern is that I would like to use an ActionBar which sounds the opposite of what Google wants (both theme have NoActionBar: Theme.Holo.NoActionBar.TranslucentDecor Theme.Holo.Light.NoActionBar.TranslucentDecor As I don't plan to use some hacks or tricks to make it work, I just wanted to know if there was some correct way to achieve this or if this would be against Google guidelines.

• Finding App Id under .ipa or .app

  - by Rafael Oliveira

  I'm building an application that search and recognizes any iPhone apps that user has in his/her computer. I would like to know a way to "extract" the id of the application from the .ipa file. I was trying to do the recognition using only the App File Name, but I discovered that the File Name is not the name of the app in Apple Store. Live Poker 6K Free by Zynga != Live Poker 3.7.ipa The id i'm talking about is the app id, like in, http://itunes.apple.com/app/live-poker-6k-free-by-zynga/id354901953?mt=8 the id is 354901953. Does any body has a clue how can I manage to find this information?

• Building a Universal iPad App - Where is the device recognition code?

  - by JustinXXVII

  I noticed that when I create a new project in XCode for a Universal iPad/iPhone application, the template comes with two separate App Delegate files, one for each device. I can't seem to locate the place in code where it tries to decide which app delegate to use. I have an existing iPhone project I'd like to port to iPad. My thinking was that if I went ahead and designed the iPad project, I could just import my iPhone classes and nibs, and then use the App Delegate and UIDevice to decide which MainWindow.xib to load. The process went like this: Create an iPad project coded as a split-view create brand new classes and nibs for the iPad import iPhone classes and nibs Change build/target settings in accordance with Universal Apps Use [[UIDevice currentDevice] model] in the AppDelegate to decide which MainWindow to load Will this work, or does the app just automatically know which device it's being deployed on? Thanks for any insight you can offer.

• LinearLayout of a WebView and a Button.

  - by Timmmm

  Hi, I recently struggled with an apparently simple Android layout: I wanted a WebView above a Button. It worked fine with the following parameters: WebView: Height: wrap-content Weight: unset (by the way, what is the default?) Button: Height: wrap-content Weight: unset However if the web page became too big it spilled out over the button. I tried various combinations of weights and heights, and all except one either completely hide the button, or partially cover it. This is the one that works (copied from http://code.google.com/p/apps-for-android/source/browse/trunk/Samples/WebViewDemo/res/layout/main.xml): WebView: Height: 0 Weight: 1 Button: Height: wrap-content Weight: unset If you change any of those, e.g. give button a weight or change the WebView height to wrap-content then it doesn't work. My question is: Why? Can someone please explain what on Earth the android layout system is thinking?

• Android: No icon for Notification

  - by Omer

  Hello, I wanted to create a notification without the icon in the status bar (the state that is not expanded). I tried the custom expanded view and set the icon for this view only. But it did not work. When I give 0 as icon to the constructor, the icon disappears but notification also does not appear in the expanded view. Notification notification = new Notification(0, "", 0); I tried a lot of combinations but didn't come out with a solution. By the way, I know it is working because I saw this feature in some apps. Thanks.

• Open source alternative to WebEx WebOffice?

  - by Dieseltime

  I have a client who has been using WebOffice (from WebEx) for a variety of tasks within their small organization. The problem is that they only really need a small subset of the features WebOffice provides (Contact list, Database, and Document Storage). They've asked me to develop a website focused on these three features with the rationalization that this should be more cost-effective, since they currently aren't using many of the features of WebOffice they pay for. What are some open-source alternatives that I could implement for them? Sharepoint sounds like it would be too bloated and Google Apps may not be as collaborative as they would like.

• Compiling python modules whith DEBUG defined on MSVC

  - by DaedalusFall

  Python rather stupidly has a pragma directive in its include files that forces a link against python26_d.lib when the DEBUG preprocessor variable is defined. This is a problem because the python installer doesn't come with python26_d.lib! So I can't build applications in msvc in debug mode. If i temporarily #undef DEBUG for just one file I get many complaints about inconsistent DLL linkage. If I change the pragma in pythons include file I get undefined references to various debug functions. I have tried compiling my own version of python but its somehow different enough from the python that gets distributed that I can't use my modules with apps built with the vanilla version of python Can anyone give me any advice on how to get round this? Thanks

• Ajax Enabled WCF Service Javascript issue...

  - by Captain Insano

  I'm a noob working with Ajax-Enabled WCF Services... Right now I have an AJAX service which calls a different WCF service that is using wsHttpBinding. The WCF wsHttpBinding service lives in a different web app on the same IIS6 server. The AJAX javascript proxy is only created when I enable anonymous access on the app hosting the AJAX service. If I remove anonymous access, IE6 bombs with an 'Undefined' error when call the AJAX proxy. In a nut shell, my AJAX service sends a request back to IIS (same domain/app), and while on the server it sends a WCF service request for data on a different app on the same IIS server. The service returning data is setup with Windows authentication, wsHttpBinding, and security mode is set to message. Any ideas? Both apps have are using windows authentication.

• Best practice for sharing code between OSX and IOS app

  - by Alberto

  I am creating an iOS version of an existing OSX app and am wondering what the best practices are for sharing code between the two. The code in question only depends on the foundation framework and the Sqlite dynamic library, so it should compile and run fine on both platforms. It seems to me there are three possible options: Create a single project with and OSX and an IOS targets, add source files to each target as appropriate. Create two separate projects for the OSX and IOS apps, put shared code in a common location in the workspace and add it as reference to both projects. Create three projects: OSX app, IOS app and a shared static library with an OSX and an IOS targets; add each library target to the respective application. Is there any reason one of the above approaches may be better than the other two? If not, option 2 seems to be the simplest by far.

• Connecting to a SQL Server Compact Edition (.sdf) from an MFC application

  - by Hazerd

  Hey ! I'm building an MFC app in Visual Studio 2008 which classifies textures and I need some sort of lightweight database to hold the characteristics (just some doubles and strings) which can be: -carried around with the app on different computers; -be able to perform queries on it from the app (searches , updates ,inserts ,etc); Currently I'm looking into SQL compact edition because it was very easy to create from Visual Studio ( I also need only one table) but I having a hard time connecting and updating the db from C++. This is what I've found on msdn regarding C++ and SQLCE: public: void createSqlCeConnection(){ SqlCeConnection* myConnection = new SqlCeConnection(); myConnection->ConnectionString = "DataSource = blabla.sdf"; MessageBox::Show(String::Format( S"Connection State: {0}", __box(myConnection->State))); } Unfortunately my experience with .net apps is pretty limited. Hopefully you bright minds could tell me if I'm on the right path and what links and includes should I add for this to work with an C++ MFC projects. Thanks !

• Css editor with certain features

  - by user255408

  I need a light css editor with certain functions. Already downloaded and tried a few apps but still no luck, none of them fit my requirements. Actually, there is one, CssEdit (or TextMate), but unfortunately i'm a windows user... Already tried: built-in NetBeans IDE css editor (btw nice editor, the one i'm using now for css) IntelJ IDE (very good html and css editor, but using the entire ide just for this - that's crazy) ArduoCss (very buggy in win7 environment) Notepad Notepad++ (it rules, but as i said, i need something more functional for css editing) Style Master ( if i don't find anything else, probably i'll choose this one) Stylizer ( also might be my choice, but it's black interface kills me, also extremy noob-oriented, i even couldn't find a way to see the source code) Some of the features i am looking for: grouping by comments like here snippets autocomplete, if i type for instance f-s, it should recognize and expand it to "font-size" property color picker The editor must have at least the first feature that i listed above. Sorry for my poor english.

• Django/MySQL - __istartswith not producing case-insensitive query.

  - by TheLizardKing

  I make use of generic views and I am attempting to query my MySQL db (utf8_bin collation) in a case insensitive manor to try to find all my song titles that start with a particular letter. view.py def tracks_by_title(request, starts_with): return object_list( request, queryset = Track.objects.filter(title__istartswith=starts_with), template_name = 'tlkmusic_base/titles_list.html', template_object_name = 'tracks', paginate_by = 25, ) and my urls.py urlpatterns = patterns('tlkmusic.apps.tlkmusic_base.views', (r'^titles/(?P<starts_with>\w)/$', tracks_by_title), ) the query it produces according to the django debug toolbar is: SELECT `tracks`.`id`, `tracks`.`url`, `tracks`.`artist`, `tracks`.`album`, `tracks`.`genre`, `tracks`.`year`, `tracks`.`title`, `tracks`.`comment`, `tracks`.`tracknumber`, `tracks`.`discnumber`, `tracks`.`bitrate`, `tracks`.`length`, `tracks`.`samplerate`, `tracks`.`filesize`, `tracks`.`createdate`, `tracks`.`modifydate` FROM `tracks` WHERE `tracks`.`title` LIKE a% LIMIT 1 specifically this line: WHERE `tracks`.`title` LIKE a% LIMIT 1 Why is it not ILIKE which is what I was expecting by using __istartswith? I am using Django 1.1.1 on Ubuntu.

• How-to build a droplet application in Xcode4?

  - by Josh

  In Xcode3 there used to be a template to build "Droplet" Applications (head/nibless apps that would throw whatever dropped at them at an "on open" Applescript method). In Xcode4 this template is unfortunately gone. What are the required steps to setup an xcode4 droplet project? modify the info.plist i guess to make the app handle drops get rid of the nib (also involves changes in main.m and both AppDelegate.h and AppDelegate.m i guess) Maybe somebody even still has Xcode3 installed and could create an empty applescript droplet app and upload it somewhere? that would be very interesting. thanks! (or is there maybe even a way to export an app bundle created with the AppleScript Editor to Xcode?)

  I try to send an specific iPad Application to iTunes connect before March 27 and as Apple says: "Only iPad apps compiled with iPhone SDK 3.2 beta 5 will be accepted for this initial review." So I compiled my application with iPhone SDK 3.2 beta 5 with a distribution provisioning profile. But when I upload my application on iTunes Connect, I have the following error: "The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the application" For sure, it's the beta 5 ! Have you got an idea? Thank you in advance. Fred

• What is node.js?

  - by Jeffrey

  I don't fully get what node.js is all about. Maybe it's because I am mainly a web based business app developer. Can someone please explain what it is and the use of it? Thanks. My understanding so far is that: The programming model is event driven, especially the way it handles IO. It uses javascript and the parser is V8. It can be easily used to create concurrent server apps. Are my understandings correct? If yes, then what are the benefits of evented IO, is it just more for the concurrency stuffs? Also is the direction of node.js to become a framework like, javascript based (v8 based) programming model?
