Combobox dropdown

I have a control similar to a combobox. When I click on the button to display the dropdown list (a WS_POPUP window), the main app. window's titlebar greys out. I know this is the normal behavior. My question is how do I mimick the combo box's behavior by keeping (or at least appearing to keep) the title bar active when the dropdown window appears.

Thanks,
Karen

Don't use the WS_POPUP style. Use WS_CHILD, with GetDesktopWindow. If you have problem with refection messages, you have to create a window which purpose is to forwarrd all reflected messages to your WS_CHILD window.
