Assuming you have the top-most window of the app, you should be able to
use FindWindowEx to find the tab control by class name; you shouldn't
have to enumerate for it.  After you send TCM_SETCURSEL, you should be
able to call InvalidateRect to force the window to redraw.

Do you have the Windows SDK installed?  You can use the "spyxx" tool to
explore the window configuration of the app you're examining.
