• Mike Henderlight Header file incompatibility causes compiler errors

  The following source code causes numerous compiler errors in msxml.h: #define version 438 #include <afx.h> Naming the variable something other than 'version' makes the errors go away. This suggests an error in macro definitions in one of MS's header files. I agree that the "const int" way you suggest is better than the "#define" way, in this case. However, the MS developers ...Show All

• Ralf Hedler NULL STL string exception with 2005

  The following code properly throws an exception that is caught in the "catch(...)" below on Visual C++ version 6.0 and Visual C++ 2003. However, an exception is thrown that is not caught and a CRASH occurs on version 2005 of Visual C++. This seems like an extremely serious bug to me. Does anyone know: 1.) Is this a confirmed bug by Microsoft 2.) Is there a safe way around it. By "safe" I do not mean "just don't ...Show All
