atlbase.h not found when using Visual C++ Express 2010

Question

So I tried moving my project to Visual C++ Express 2010 on Windows 7 from a previous version on Windows XP. I got all sorts of errors where atlbase.h was not found. This isn't so much a question but I wanted to document what my resolution was for others.

Copied the following PlatformSDK files from my previous install and put them on my Windows 7 machine.

PlatformSDK/include/atl

PlatformSDK/include/mfc

PlatformSDK/lib

PlatformSDK/src/atl

I then change the VC++ Directories in the project Properties to point to those directories.

Include Directories-

*include/atl

*include/mfc

Library Directories-

*lib

Source Directories-

*src/atl

Make a change to stdafx.h

right after this line: #include "atlbase.h"

add this line: extern CComModule _Module;

Hopefully you're ready to go now! Probably not but perhaps you are well on your way.

Answer 1

this is probably because the previous version that you were using was visual c++ 6.0 and that doesn't support it
