invoke a hint

Hi..

I have a form with the minimize and maximize buttons of the caption bar
removed via the forms object inspector. However, I have created my own
custom versions of the min & max buttons in there place. My question is, how
can i get windows to show the normal hints it would usually process for
those buttons? Is there a way to full windows to think they are still there
by using the sendmessage function(with the specific parameters), or do Ihave
to create my own hints?

Thankyou.
