Changing the background color of a check box...
Jeremy,
In order to add change the background color of a check box, bring up the
Class Wizard for the Dialog that has the check box you want altered. Under
Messages, Select the WM_CTLCOLOR item and add a function. You will have to
add a switch statement in order to filter out the type of control that you
want. If you want to single out a specific control, then use the CWnd
pointer to determine if you have the control that you want. Then use the
appropriate color function.
I have included the header for one of my versions of the command. I was
doing a null pointer in the background to allow the textured background show
through. But that's a whole other story.
Hope that this helps.
