Re: CFileDialog crash on Vista

I have tried changing to _WTL_NO_CSTRING but the problem still occurs. I did install VC 2005 on my vista machine and recompiled the app there, but the problem still occurred. The good thing is that I could step through the code with the debugger to the point where it crashed. It happens in the DoModal call of the CFileDialog at the following line: 

bRet = ::GetOpenFileName(&m_ofn);


I have been reading that Vista handles the FileDialogs differently than XP did and there are various references to GetOpenFileName, but I cannot figure out what I should do here.

I have been googling the problem and it turns out that the CFileDialog are handled differently under Vista, but I could not really find a solution to the problem. Does anyone have a hunch what could cause this problem? Do I need some special entry in stdafx.h or use a particular compiler flag? This is what my stdafx.h looks like
