Maximize first MDI child

In my MDI application, I want the main window to be maximized and the first
MDI child window to be created with the size of the client area of the 
CMDIFrameWnd. If I use rectDefault to create the MDI Child and then maximize it,
then when the next MDI child window is created, the first one gets resized to 
rectDefault. I always want the first MDI Child window to be maximized, so I 
think that while creation itself, I have to create it with the max size i.e. 
the client area of the MDI Frame. How should I do this ?

Environment : VC++ 4.0, Windows 95

Thanks

Easy...
Override  void CChildFrame::ActivateFrame(int nCmdShow)
where CChildFrame is the class of your mdi child frame window.

Example:
void CChildFrame::ActivateFrame(int nCmdShow)
{
   if (nCmdShow == -1)
       nCmdShow = SW_SHOWMAXIMIZED;

   CMDIChildWnd::ActivateFrame(nCmdShow);
}
(You may want to put in a test for the 'first' window, as this stands now, it will maximize every CChildFrame it shows.)

G'day!
In any MDI application I run, maximizing Window "n" has no
effect on a maximized Window 1  --  it does not resize.  Are you
certain you aren't doing something to the sizing elsewhere?  An
inappropriate SetWindowPlacement?         Regards,  Jim LW

Hello!

In Jim Leavitt's reply, he has told that the ActivateFrame() of Child =
window will test for nCmdShow. But, if you put it in CChildFrame class, =
it may not work. Since the value of nCmdShow is set to -1 every time the =
window is created, everytime the new window will be maximized regardless =
of the size of the existing children windows.

Probably, you may do the following:

Declare a flag in your CWinApp class and set it to TRUE in the App =
constructor. In your ChildFrame::ActivateFrame(), check this flag for =
TRUE and if it is so, set nCmdShow to SW_SHOWMAXIMIZED and otherwise, =
leave its value as it is.  This will work exactly like what you want in =
your MDI application.

Cheers,
