Your message handler function has the wrong prototype. It should return
LRESULT instead of UINT. They used to be equivalent, but with 64-bit source
compatibility and improved compiler checking of the prototypes your old code
has a roadblock to progress. If you're not familiar with the message map
stuff you might want to just delete the function and message map line, then
add them again using the wizard.
