Visual 2010 MFC new project doesn't build!

Question

I just created a new project in Visual 2010. It is a multi-document MFC (static link) application with the HTML help option, Visual Studio 2008 style (with style changing option), that's about it.

Just after creation, I hit Build Solution and I get a lot build errors all in afxcomctl32.h. Errors like:

Error 1 error C2061: syntax error : identifier 'LPCWS' C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\include\afxcomctl32.h 426 1

On this line: AFX_ISOLATIONAWARE_STATICLINK_FUNC(HWND ,CreateWindowExW,(DWORD dwExStyle,LPCWS TR lpClassName,LPCWSTR lpWindowName,DWORD dwStyle,int X,int Y,int nWidth,int nHeight,HWND hWndParent,HMENU hMenu,HINSTANCE hInstance,LPVOID lpParam),(dwExStyle,lpClassName,lpWindowName,dwStyle,X,Y,nWidth,nHeight,hWndParent,hMenu,hInstance,lpParam),NULL)

Same errors in Debug and Release.

My PC is Windows 7 Ultimate. What's the problem??? Best regards, Downy

Answer 1

AFX_ISOLATIONAWARE_STATICLINK_FUNC(..., LPCWS TR lpClassName, ...)

That code got messed up, there is a space or tab inserted in LPCWSTR. Deleting it will fix the problem.

However, that changed the timestamp on the file as well, you may run into trouble when you install a future service pack. One thing to try is to rename the file, then run a Repair to get the original file back. Or copy it off another machine.
