• Visual C++ Using MFC regular mixed mode dll (/clr) from a managed application with Visual Studio 2005 Beta 2

  Hello all, I am having problems using MFC within a managed application in Whidbey. What I try to do is the following: Writing a dll in C++/CLI that uses MFC. In this dll I implement managed wrapper classes around e.g. MFC dialog classes. Using these wrappers I want to display the dialogs in a managed application, written e.g. in C#. This used to work with Visual Studio 2003 and managed extensions for C++ but, but it doesn't with Whidbey. I used the wizard to create a MFC regular dll that uses the shared version of MFC, then applied the /clr switch to it. Then I reference this dll in a C# application, calling a managed wrapper class of the dl ...Show All

Any ideas Can you connect to SQL Server Express and create the database manually If yes, then the issue is within Visual C# and you should post this issue on a Visual C# Express forum. If you encounter an error with manually creating the database, let us know what that error is. Thanks Laurentiu ...Show All

• .NET Development Performance issues

  the winform application i am babysitting uses webservices and my problem is with the performance of the application. when i debug and run from visual studio .net 2003 IDE the performance is ok but when i build the application and install the application, the performance is very bad. i am testing on my development machine and also on another test machine there is no difference. The data + webservices is on a seperate server in both cases. you would think that because you are debugging and there is no code optimization, the release build would be faster but the opposite is happening here. That's strange! I ...Show All

• Windows Forms Vertical text - very basic question

  Sorry, but this is a very basic thing that I just can't seem to figure out. I'm creating a data plotter and need to add a vertical axis label. However, I haven't been able to take a regular label or text box and rotate it 90 degrees. Any suggestions I really just need a way to display variable text vertically. I would prefer a way that would have the text facing to the right instead of something like the following: t e x t Thanks.

• Visual C# Having troubles with Randomness

  I am new to these boards so not sure if I should post code snippets or how you guys handle things. Basically the issue can easily be seen here: http://www.thecodeproject.com/csharp/CsharpMersenneTwister.asp If you don't have an account there you can just download the binary called the demo. When you run this simple dice program you can see that it always has the same results. Do so by running it, memorizing the number of rolls for each number at the bottom right, close the program, and run it again and perform the same action. Given that these results in that one iteration are seemingly random. I want to create a program that ha ...Show All

• Visual Studio Team System Testing Native Code (C++ ) using Team Unit Testing frameworks

  I have been looking for some pointers or guide lines as to how do I test C++ unmanaged code using Unit Tesing capabilities of VS 2005. Do I need to write wrappers in managed code ( a sort of mixed mode class one that calls into managed code and other that calls the native code) Any suggestion welcome Regds Dinesh I don't see any workaround for this. For ExpectedExeption attribute you can specify either managed exception type or type + error message. For unmanaged exception you would get something like System.Runtime.InteropServices.SEHException. If you need to verify what's inside and the test in in C++, don't use ExpectedException ...Show All

• Visual Studio Force a target to rebuild?

  I have a target that I would like to run twice during my build.  Once, before I do any work, I want to clean up some files in a directory.  Then, later on in the build, after I've created some files, I want to do the same cleanup on the same directory using the exact same algorithm.  Is there a way to call my target again and force it to run The only thing I could think of doing was using the Exec task to run MSBuild.  CallTarget and MSBuild both remember what targets have already run, so that won't work. Dependency checking is awesome...except when you don't want it. Many thanks,    Taylor ...Show All
