Win32 API Graphical Controls - How to Redraw

Note: I'm new to this forum so please advise if there's a better place to post this.

I'm working with VBA for Excel 2003. I created UserForm1 and added a command button. I can manipulate the properties of UserForm1 using the form's hwnd. For example, I stripped the border, max/min, and caption properties. I'd like to create the same uniform look for child controls such as the button but graphical controls don't have handles. Is there a way to redraw graphical controls using the API? BTW, I've posted this question on Stackoverflow and Bytes but no one has posted a solution. Thanks very much for your help.
