conflict with MFC versions using unicode and CDatabase

Asked by JohannRamon in Windows MFC Programming, C++ Programming Language, Microsoft Visual C++

Tags: , , ,

Hi people!

 

I'm having a big problem:

I'm migrating a big project from VC++6 to VC++8 (2005) and i'm stacked with a .exe project that was converted to unicode; the debub version works fine, but the release version throws crazy exceptions. I was reading about CDatabase bug using unicode in mfc42, but i supposed i'm working on mfc80... i think.

I attach a little portion of my code.


My debug version is fine, but in my release version i had to convert the unicode string back to char and cast to wchar_t* and it works, but i´m having a lot of troubles after that.

 

This link talks about that: http://support.microsoft.com/kb/139759/en

 

I wanna know what is the problem; MFC Version, CDatabase, other?

Both projects are unicode, but the dll projects only works if it is debug.

 

Thanks a lot!

#ifdef _DEBUG
   Result = pDatabase->OpenEx(Key, CDatabase::openReadOnly | CDatabase::noOdbcDialog ); // ANMB VS2005 'Key' is an Unicode CString
#else
   Result = pDatabase->OpenEx((wchar_t*)StringClass(Key.GetBuffer()).ToChar(), CDatabase::openReadOnly | CDatabase::noOdbcDialog ); // ANMB VS2005 'StringClass' converts from Unicode to char
#endif
