If you do your work on the GUI thread (preventing messages from being
pumped), then try CWaitCursor (WTL 3.0+) or CCustomWaitCursor (WTL 7.1).

If messages are getting pumped while doing the lengthy operation, then
you have to be a little more creative. One option is to handle
WM_SETCURSOR for every window the mouse might move over. Another is to
set a message hook for WH_CALLWNDPROCRET, and force a wait cursor on
WM_SETCURSOR while the operation is going on.
