(NTDLL.DLL):0xC0000008:Invalid Handle.

[FockuSS]

The simpliest code such

void CTestAppDlg::OnButton1() 
{
	CFileDialog dlg(TRUE);
	dlg.DoModal();
}

gives me en error on debbug. Message box (First-time exception in TestApp.exe(NTDLL.DLL):0xC0000008:Invalid Handle.). My call stack

Please help me to solve this bug as I tried for few days already with no luck.

The suggestion is to step into both constructor and DoModal and see what happens there.

Found the problem! Removed from computer software using overlayicon.dll and everything works fine. Probably was some conflict there. Thanks everyone.

Hi FockuSS

I have the exact same problem but could not understand how exactly you solved it. :-(

Can you tell me more about your solution ? How did you identify the app that messes with the overlayicon dll ?

Thanks a lot !
