ok, I have seen a lot of threads about changing button color but.... (some using MFC, what confuses me...)

I could not understand where I should put the notification...
case WM_CTLCOLORDLG:
and how to handle this.

It it inside my DialogProc...or I should do a ButtonProc....

I could change the color of my Dialog ... (DialogProc), but not of my button.

What I want to do, to simplify, is when I press a button 1 I want to change the color button 2.

Someone could write some words about it to clarify this issue (please WinAPI).

Thanks
