Enter key does not trigger IDOK Default Push Button action

Question

I have a CDialog derived class. Its interface definition has several picture boxes and some buttons after, defined in resource file as:

IDD_SELECT_ITEMS DIALOGEX         


        

Answer 1

The solution was right in front of my eyes in a comment, and I was completely blind, not seeing it!

After seeing the end of the "The WM_INITDIALOG Message" section on Dialog Box Programming Considerations, I understood I had to return FALSE.

I eliminated all the trashy lines I added, changed the return value to FALSE, and everything began to work fine as expected :)
