MFC OnTimer function does not compile when porting legacy code from 32-bit to 64-bit

I was recently porting an MFC C++ application that compiled on Visual studio 2005 32-bit to VS 2008 64-bit.

It turns out there is a bug in the code generated by older versions of MFC that makes it not compile on 64 bit.

The problem is with the OnTimer function signature:

afx_msg void OnTimer(UINT nIDEvent);

It should be changed to ->

afx_msg void OnTimer(UINT_PTR nIDEvent);

You can find Microsoft’s reaction to a similar connect bug report for VS 2005 at:

Hope this helps!
