>I have no idea if this will work. It's a shot in the dark, but it might. MS KB article Q178491 describes how to change the background color of a treeview control. The technique described in there might work with the Date/Time Picker. (And yes, the control does have it's own hWnd property, which you'll need for this to work).

Well George, I tried the SendMessage() part of this real quick to see if it would work but it didn't. But then I did it quick and may have done something stupid ...

Created a form, placed a DateTimePicker control on it and a button with the following code:

DECLARE INTEGER SendMessage IN WIN32API INTEGER, INTEGER, INTEGER, INTEGER
SendMessage( THIS.PARENT.oleDateTime.Object.hWnd, 4381, 0, RGB(255,0,0) )

Nothing happens, but I didn't check GetLastError() either so it may be erroring out on me.
