Joe,
I appreciate the response. Using your code would imply that the button
we SetCapture() on is derived from CWnd?

In my world, the button I am clicking on is a construct of my own, drawn by
me. The first CWnd object in the chain is the view. (starting from
smallest visual object and moving out).

.......

after reading about SetCapture() the reason to call SetCapture() is only to
ensure we get the mouseup event even IF we move the mouse pointer outside
the window. Right?

I think I got it now.

No. See below...

OnLButtonDown:
      SetCapture()
      SetTimer(...);

OnLButtonUp:
     if(GetCapture() != NULL)
         {
          ReleaseCapture();
          KillTimer();
         }

OnTimer:
    if(GetCapture())
        RepeatButtonAction();

Is the following scenario possible?

the current state is you click the left mouse button and that generates a
single WMLBUTTONDOWN message.

what if I wanted the WMLBUTTONDOWN message to keep firing until I let off
the button? Is there a setting in MFC somewhere for that? Maybe one
where
you could set the interval of the firing? Like every 100 ms or something?

thanks.
