I'm using an MFC DLL, which cannot open a CDialog with DoModal(); MFC throws an assert, because the AFX - thread seems to be NULL.
The DLL has the options "Use MFC in a static library", the compiler switches _MT, _WINDLL and _USRDLL are defined. The runtime library is "Debug multithreaded".
A routine is called from my main application, and the main thread (CWinApp) from there wants to open a Dialog with DoModal. I can step into AfxGetThread(), and there I see that the CurrentWinThread (from the ModulThreadState) is NULL, and then AfxGetApp() also yields NULL.
How can I tell the DLL that its thread is the one from the calling application ?
