The error C2039: 'OutputDebugStringA' : is not a member of '` global namespace'
But atltrace. H is the official documents of the MFC,
I tried a new empty project under vs2015, you can compile successfully, and then add the old h and CPP file to empty project, compile error, the paper surface errors,
Beg for understanding of superior and see how to solve, thank you very much!

The link with Kernel32. Lib

CodePudding user response:

The Header
WinBase. H (include Windows. H)
The Library
Kernel32. Lib
DLL
Kernel32. DLL

CodePudding user response:

My project has been added Kernel32. Lib links, but atltrace. H is MFC system files, I don't need to manually modify,
Another is not add old h and CPP, compiler will not be submitted to the wrong, so feel atltrace. H itself should be no problem

CodePudding user response:

Should have other questions, and adjust the head file order,,

CodePudding user response:

Mainly atltrace. H is the file system, according to the previous performance is not like system files out of the question, but I don't know is which file has a problem, so don't know what to order, please give advice or comments
