Try this (i don't test it) :


WINDOWPLACEMENT pl;
child.GetWindowPlacement(&pl)
pl.flags=WPF_RESTORETOMAXIMIZED;
pl.showCmd=SW_SHOWMAXIMIZED;
child.SetWindowPlacement(&pl)




Hop this works.

There is no need to remove WS_OVERLAPPEDWINDOW. Should all child frames be maximised? I can't see why you would only want one to be maximised. To create them maximised, override CChildFrame's PreCreateWindow() and add:

cs.style |= WS_MAXIMIZE

They will always fill the maximum space when they are created, then.

Does this help?

Hello Jason Teagle,

Thank you for your response. Intially i want to show my application as SDI even though it is an MDI.SO,
I remove, ws_overlappedwindow...as to said i done the case thing but it give me a result.........

I think you have to use the code when you want the window to be maximized.

But i think there is a little mistake in code.
So try this :


WINDOWPLACEMENT pl;
child.GetWindowPlacement(&pl)pl.showCmd|=SW_SHOWMAXIMIZED;
child.SetWindowPlacement(&pl)

I understand why you removed WS_OVERLAPPEDWINDOW now, to remove the minimize, restore and close boxes from the child frame. You will still need to logical-OR in the WS_MAXIMIZE bit during your override of CChildFrame::PreCreateWindow() to make it fill the whole space, though. You will also need to override the CWinApp::OnFileNew() behaviour to call CDocTemplate::SaveAllModified() and CDocTemplate::CloseAllDocuments() before opening the new document, so that you only have the one document open at a time, as with SDI.

I have a relatively simpler solution. On the closure of a child window, post a custom message to the main frame window. In the message Handler, maximize the active child (Obtained through 'MDIGetActive' fn).

hello

Thank you for your repsone..yes you got my idea...i got the solution in precreate window() i made cs &= ~system_menu instead
of overlapped window which behaves as i want........once again thankyou....
