Successfully built project doesn't show app window [modified]

[Jose M Castellanos]

Hello: I am building a project like this on VS2003: - C# test app (Windows form) - Managed C++ main DLL (exports several user controls) - Legacy C++ DLLs Some days ago I started to experience a problem when trying to debug it. I started the application for debugging, VS entered debug mode, but I couldn't see my form Window. If I open the task manager, my process is there but with a 0% cpu time. Now it happens more and more frequently. Sometimes I just add a blank space to a file, compile again and my app can be debugged regularly. Of course I have tried to rebuild my app, delete Debug/Release folders of my projects and open/close VS ... Any idea about what can be happening? Answers will be really welcomed. -- modified at 7:12 Thursday 4th January, 2007

Have you tried enabling the Unmanaged Code Debugging under Debug for the C# application. You may have an intermittent problem that will show up if you are debugging both managed and unmanaged code.

Yes, I had activated unmanaged code debugging, so it must be due to a something different. The problem apperars and disappears without changing any of the project settings.
