I am going to guess that you made your own solution from scratch, rather than upgrade the existing one.
ChildView.h and ChildView.cpp are not used in the actual project. Remove these from your solution.
Once you have done that, there is only 1 thing that needs changing. Microsoft changed the way registered thread messages are implemented, and a return value is no longer needed. Below are the only changes you should need to make to get it compiling.
QuickWin.h
afx_msg void OnStdioCommand(WPARAM wParam, LPARAM lParam);
QuickWin.cpp
void CQuickWinApp::OnStdioCommand(WPARAM wCommand, LPARAM lParam)
I couldn't actually get it to do anything useful, so there must be something else that needs changing too, but I don't have the time to search for it. Hope this much helps.
