Change background color and name in MFC Control

Question

I want to change the text color and background color for my EDIT CONTROL, STATIC CONTROL and BUTTON CONTROL in an MFC application. The control is in a dialog CDialogEx.

I am trying to add OnCtlColor (with a wizard in visual studio, in the WM_CTLCOLR message), but I cannot set the color of the static control and button controls.

I also set a breakpoint in the function OnCtlColor(in the IF construct), but I get nothing.

I also tried using the function SetTextColorby getting the control handle from GetDlgItem, but I cannot change the color as I want.

Please help me.
