Hello! I have C++ DLL and VB client. In C++ DLL there is a function to setting callback function. Accordingly, VB call this function (in C++ DLL) and pass pointer to own callback function. When one event is occured, C++ DLL calls this VB callback function. I have to do some operations with new...

Well. I wrote class (see above) and all worked fine but later I noticed that I was in debug mode again... As far as I understood there is following problem: In EXE-server, built with ATL COM AppWizard (_ATL_FREE_THREADED), in ReleaseMinDependency I can't use any global class objects. F.i. I...

Hi! I've encountered with one problem and I don't understand what's wrong. I created EXE-server with ATL COM AppWizard (free thread, _ATL_FREE_THREADED). And I use static CComAutoCriticalSection m_cs; in my class. I defined this object: CComAutoCriticalSection MyClass::m_cs; And all is ok in...
