I got this to compile, but it's not popping my Dialog box.
The tutorial from www.winprog.org/tutorial didnt necessarily specify where my AboutDlgProc() is suppose to go ?
I assumed it went above the Default but I am unsure... I'm trying to understand why it's not popping my Aboout Dialog when I press HELP -> ABOUT
