win32 API Dialog problem

[CodyOebel]

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

               EndDialog(hwnd, IDOK);
               break;

can't find the ID for the HELP button..where is it?..

case [B]ID_ABOUT[/B]:
        {
            int ret = DialogBox(GetModuleHandle(NULL), 
                MAKEINTRESOURCE([B]ID_ABOUT[/B]), hwnd, AboutDlgProc);

HINT : use a different command ID from the dialog ID..:)

ABout your hint... IM just stumped... I double checked to ensure no syntax was missing etc. Instead of using case ID_ABOUT, I swapped it to case 9003: using the identifier number, but the same problem persist. I dont want to re-vamp the entire code or use the tutorials exact code because I wont learn why this is happening. So before I continue furtehr into the tutorial I said to myself I must first understand why this is happening. Even if the answer is given to me! It's bugging the heck out of me LOL.
