Hi! May be WM_SHOWWINDOW will help you (when minimasing wParam  is equal SW_MINIMIZE)

Here is what I would do:
SendMessage (hHandle, WM_SYSCOMMAND, SC_MINIMIZE, 0);

That will minimize the window referred to by hHandle.  Is this what you were looking for?

What you want to do is to handle the WM_SYSCOMMAND message.  In the message handler check if the wParam is SC_MINIMIZE.  If it is, then do your special processing and return.  If not, then pass the message and parameters to the default window procedure.

Let me know if you have questions.

Hello all!

Here is what I would do if I were you....

To minimize...

ShowWindow(hHandle, SW_MINIMIZE);

To maximize...

ShowWindow(hHandle, SW_MAXIMIZE);

where hHandle is the handle to the window to be minimized or maximized..

Hope this helps!
