>>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).

Bill,

When I get a chance I might take a shot at it. I'll let you know.
