• Xcode 3.2 + LLVM = no local symbols when debugging

  - by glebd

  I have a project for Mac OS X 10.5 that I'm building on 10.6 using Xcode 3.2. When I use GCC 4.2 for Debug build and hit a breakpoint, Xcode debugger displays local variable information normally. If I choose LLVM GCC 4.2 or Clang LLVM, when I hit breakpoint, local symbols are not available, and GDB says No symbol 'self' in current context if I try to print self or any other local symbol. In all cases Generate debug info option is set. The Debug configuration is set to $(NATIVE_ARCH) and 10.5 SDK, Build active architecture only option is set. When GDB starts, I can see it is being configured as x86_64-apple-darwin. I must be missing something obvious. How do I make GDB show local symbols when using a LLVM compiler?

• Visual Studio 2010 does not discover new unit tests

  - by driis

  I am writing some unit tests in Visual Studio 2010. I can run all tests by using "Run all Tests in Current Context". However, if I write a new unit test, it does not get picked up by the environment - in other words, I am not able to find it in Test List Editor, by running all tests, or anywhere else. If I unload the project and then reload it; the new test is available to run. When I am adding a unit test, I simply add a new method to an already existing TestClass and decorating it with [TestMethod] attribute - nothing fancy. What might be causing this behaviour, and how do I make it work ?

• Devise within namespace

  - by Harm de Wit

  Hey, I'm trying to split my rails project in a front-end for regular users and a back-end for admins. Therefore i have created a namespace 'admin' so that i can easily control admin specific controller methods/layouts/authentication in the map admin. I'm using Devise to register/authenticate my admins only. Because it is only used for admins only i'm trying to move Devise to the admin namespace. I could not find exactly what i was looking for in the documentation of Devise but i tried something like this in routes.rb: namespace 'admin'do devise_for :admins end I also tried to make a custom Devise::Sessions controller but that too didn't seem to work out. Does anyone know how to do this? Should i just use the regular routes for devise with a custom(admin) layout?

• Is it feasible to write a Firefox plugin to make use of ActiveX control on Windows?

  - by Gary B2312321321

  I use an ActiveX control called TAPIEx enabling TAPI phone system integration using MS Access 2000 (+Visual Basic). I want to turn this Access database into a web app with the clients running Firefox (all on internal network). Since Firefox doesnt support ActiveX is it feasible for me to write a Firefox plugin that in turn utilizes the ActiveX control? With regard to how plugins work - Would I be able to call 'functions' of the plugin from page script (eg dial call specifying phone number, check if calls in process)? Would adding these functions to the Firefox right click menu 'globally' inside Firefox be easier? Hope you guys can help. Note I'm not a fulltime programmer; I just need to know how steep the learning curve will be or even if my idea is possible! Ive now found a project to allow using activex controls in firefox that seems to be quite up to date at: http://code.google.com/p/ff-activex-host/

• problem running system.net.webclient and process.start off a control event

  - by Rob

  The following code causes my vs 2008 wpf project to hang, I'm not sure why. Both Part 1 and Part 2 work perfectly fine independently, but when I run them together on an control event (click a button for example) the program hangs. I've also tried shell execute for part 2 - same results. However, this code when run within the form loaded event works fine. Any insights would be truly appreciated. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click 'Part 1 Dim myWebClient As System.Net.WebClient = New System.Net.WebClient Dim CurrentDataFileContents As String = myWebClient.DownloadString("http://www.xyz.com") myWebClient.Dispose() 'Part 2 System.Diagnostics.Process.Start("http://www.test.com") End Sub

• Ruby on rails link_to syntax

  - by mizipzor

  After following a tutorial Ive found. Im now redoing it again, without the scaffolding part, to learn it better. However, editing my \app\views\home\index.html.erb to contain: <h1>Rails test project</h1> <%= link_to "my blog", posts_path> I get an error: undefined local variable or method `posts_path' for #<ActionView::Base:0x4e1d954> Before I did this, I ran rake db:create, defined a migration class and ran rake db:migrate, everything without a problem. So the database should contain a posts table. But that link_to command cant seem to find posts_path. That variable (or is it even a function?) is probably defined through the scaffold routine. My question now is; how do I do that manually myself, define posts_path?

• Setting up gcov in Xcode 3.1

  - by Algorithmic

  I'm trying to setup my Xcode project to be instrumented with gcov so I can determine the code coverage of my unit tests. All of the documentation I find online talks about settings that I don't find in Xcode 3.1, though. An example: To work with Coverstory, first you need to set up your target to work with gcov. This requires turning on "Instrument Program Flow", "Generate Test Coverage Files" and linking with the gcov library. (Using Coverstory) The closest thing I can find to "Instrument Program Flow" and "Generate Test Coverage Files" in my build settings is "Generate Profiling Code", which doesn't appear to do what I want it to do. Am I looking in the wrong place for these settings or are all of the examples I'm finding online stale?

• How to manipulate the GL.bindframebuffer to target to bind GL_EXT_framebuffer

  - by Alan

  I'm trying to change the framebuffer object from GL_ARB_framebuffer and force it to use GL_EXT_framebuffer since my system is not compatible with the first one. Where in the solution do I need to implement this and how? more information on my problem whenever I create a new Windows OpenGL project from Visual Studio using MonoGame i get the error "cannot find entry point in glbindframebuffer in opengl32.dll" since the framebuffer it uses is GL_ARB_framebuffer which is only supported in Opengl 3 so in a github post i read Gihub post where they suggest this patch that in order to patch you need to force the frame buffers to use GL_EXT_framebuffer but I dont know how to force them to use the EXT instead of the ARB , btw Im using Opengl v2 Mobile intel 4 series card, which is Opengl v2 and ARB needs Opengl v3.

• Wrapping WPF UserControl inside VisualStudio Item Template

  - by karthik84

  I am currently started working on a project which will allow users to design reports inside visual studio. Previously, for my similar Winforms App, I had extended the IComponent (Component Class) and wrote our VS Like designer kind of custom control which will allow users to drag drop controls from the visual studio toolbox and then I export it as a VisualStudio C#&VB ItemTemplate. Now I am trying to recreate the same control using WPF considering its power, extensiblity. Could anyone shed some lights on this, on what would be the most preferable way of doing this ? Thanks in advance.

• Space-based architecture?

  - by rcampbell

  One chapter in Pragmatic Programmer recommends looking at a blackboard/space-based architecture + a rules engine as a more flexible alternative to a traditional workflow system. The project I'm working on currently uses a workflow engine, but I'd like to evaluate alternatives. I really feel like a SBA would be a better solution to our business problems, but I'm worried about a total lack of community support/user base/venders/options. JavaSpaces is dead, and the JINI spin-off Apache River seems to be on life support. SemiSpace looks perfect, but it's a one-man show. The only viable solution seems to be GigaSpaces. I'd like to hear your thoughts on space based architecture and any experiences you've had with real world implementations.

• Which processors can run CIL

  - by JonnyBoats

  Which processors are capable of running Common Intermediate Language(CIL), formerly known as Microsoft Intermediate Language (MSIL)? Clearly any machine that can run Microsoft Windows with .net qualifies as well as machines targeted by the Mono project. It would appear that the .NET Micro Framework has the ability to target other processors not covered by the above, but it is not clear to me that it uses CIL. Does anyone have a list of which processors are capable of running a program in CIL and or interpreting C# directly (as the .NET Micro Framework appears to do)?

• Unit Test ouput in MSBuild/TFS 2008

  - by Adam Jenkin

  I have a build in TFS 2008 which includes the running of a UnitTest project. I have configured my build as such that in the drop folder after each build, I get a StyleCop.log, FxCop.log and would like to place the trx or output from the unit tests here also. I can see that my unit tests are running as part of the build, however currently I cannot find were the output is saved to or find a way of setting the ouput to my drop location ($(DropLocation)\$(BuildNumber)\MyUnitTests.txt) My unit tests are included by using the following:- <RunTest>true</RunTest> ... <ItemGroup> <TestContainer Include="$(OutDir)\%2aMyUnitTests.dll" /> </ItemGroup> Can somebody help explain how I can achieve this.

• Netbeans GUI editor generating its own incomprehensible code.

  - by WarDoGG

  When creating a new project in netbeans, if i select JAVA Desktop application, it creates some code which I DO NOT RECOGNISE AT ALL as what i had learnt in swing. It imports packages such as : org.jdesktop.application.SingleFrameApplication; also, the declaration for main() looks like this : public static void main(String[] args) { launch(DesktopApplication2.class, args); } This really does not make any sense to my knowledge of JFrame, JPanel etc.. If i try to code a netbeans application from scratch, i can write my own swing app BUT I CANNOT FIND THE GUI EDITOR. How do i bring the GUI editor when creating java application from scratch ? Can anyone explain to me this org.jdesktop.application.SingleFrameApplication and other classes ? Please help. This is really frustrating.

• .Net 3.5 Chart Controls Exception

• sqlite with Perl for Windows; suitable for relocation

  - by Paul Nathan

  I need to set up sqllite for Perl on a Windows box. However - Perl is probably being run over the network from a central server, and I do not know what modules will be available on initial running of my script. I can guarantee Perl 5.8+ (activestate) or Perl 5.10+ (strawberry). Therefore, I need to package sqlite & the associated Perl module(s) in the project directory itself. Having Goggled around, I don't see any immediate zipfile to do this.

• linq to sql datacontext for a web application

  - by rap-uvic

  Hello, I'm trying to use linq to sql for my project (very short deadline), and I'm kind of in a bind. I don't know the best way to have a data context handy per request thread. I want something like a singleton class from which all my repository classes can access the current data context. However, singleton class is static and is not thread-safe and therefore not suitable for web apps. I want something that would create a data context at the beginning of the request and dispose of it along with the request. Can anyone please share their solution to this problem? I've been searching for a solution and I've found a good post from Rick Strahl : http://www.west-wind.com/weblog/posts/246222.aspx but I don't completely understand his thread-safe or business object approach. If somebody has a simplified version of his thread-safe approach, i'd love to take a look.

• Read assembly Guid without locking the DLL in an appdomain in medium trust ASP.Net

  - by ggonsalv

  Is it possible to read the GUID from the Assembly without actually loading it in the current App Domain. Normally Assembly.Load loads the DLL into the app domain. I just want to read the value. The description of the GUID is 'The following GUID is for the ID of the typelib ' if this project is exposed to COM <Assembly: Guid("DEDDE61CD-928E-4ACD-8C25-3B8577284819")> The main thing is I don't want to lock the file so that there are no errors 'Another process is accessing the file' error.

• How to introduce custom primitive key types to WCF Data Services (Astoria)

  - by Artem Tikhomirov

  Hello. We use custom type to represent Identifiers in our project. It has TypeConvertor attached and it always helped with serialization. I've tried to use WCF Data Services to expose some data from our system, but faced a problem. Astoria framework do not recognize class as an entity even though I've decorated it with [DataServiceKey("Id")] attribute. If I change type of property to Guid - it totally works :(. How could teach WCF Data Services to understand this simple class?

• cvs to mercurial conversion gets tags wrong

  - by Mark Borgerding

  I've tried all the recommended conversion techniques Mostly they manage to get the latest version of the files right, but every one of them trashes my history. Many (most?) of the tags from my cvs project have at least one file in error when I run "hg up $tag" My cvs repo is not all that complicated. Why can't anything convert it? I'd like to dump cvs and convert to mercurial, but not without history. To recap my frustration: I tried hg convert (tried --branchsort,--timesort, fuzz=0) I tried cvs2svn and then hg convert. tailor does not work with recent versions of mercurial fromcvs disappeared from the face of the earth hg-cvs-import has been abandoned for 4 years and doesn't work with recent versions of hg I have tried using the two most recent versions of mercurial ( 1.5 and 1.5.1 ).

• Why won't asp.net create cookies in localhost?

  - by James McConnell

  Okay, this is really kinda starting to bug me. I have a simple Web project setup located at: "C:\Projects\MyTestProject\". In IIS on my machine, I have mapped a virtual directory to this location so I can run my sites locally (I understand I can run it from Visual Studio, I like this method better). I have named this virtual directory "mtp" and I access it via http://localhost/mtp/index.aspx. All this is working fine. However, whenever I try to create a cookie, it simply never gets written out? I've tried this in FF3 and IE7 and it just plain won't write the cookie out. I don't get it. I do have "127.0.0.1 localhost" in my hosts file, I can't really think of anything else I can do. Thanks for any advice. James

• Trying to verify understanding of foreign keys SQL Server

  - by msarchet

  So I'm working on just a learning project to expose myself to doing some things I do not get to do at work. I'm just making a simple bug and case tracking app (I know there are a million this is just to work with some tools I don't get to). So I was designing my database and realized I've never actually used Foreign Keys before in any of my projects, I've used them before but never actually setting up a column as a FK. So I've designed my database as follows, which I think is close to correct (at least for the initial layout). However When I try to add the FK's to the linking Tables I get an error saying, "The tables present in the relationship must have the same number of columns". I'm doing this by in SQLSMS by going to the Keys 'folder' and adding a FK. Is there something that I am doing wrong here, I don't understand why the tables would have to have the same number of columns for me to add a FK relationship between the tables?
