A Question, Hiding Child frame in MDI App.
in [MFC]

From: MuMbi on 31 Jan 2010 00:39 Hi, everybody. I need to hide child frame in MDI app. But, I will use document and view in the child frame. So, I've got to hide the child frame with no destruction. ShowWindow( SW_HIDE ) makes the child frame just minimize. Is it possible to hide child frame in MDI app? I need your helps. Help me~

Are you certain you are calling the on the MDIChildWnd and and not on the view? -- Ajay

After I read your article, I tried again on View::OnInitialUpdate. Yes. The child frame hides successfully. But the view in the child frame was shown on the background of main frame, So I changed the view's parent to other pane. It's successful. But the background of main frame need to be redrawn. Here, let me ask you for helps. What window is the background of main frame? How can I access the background of main frame? thank for your helps.

There are some unbelievably rare situations in which makes sense. This does not appear to be one of them. If you ShowWindow(SW_HIDE) in OnInitialUpdate, you are hiding the wrong thing; you are hiding the view window inside the child frame. **** > >It's successful. > >But the background of main frame need to be redrawn. > >Here, let me ask you for helps. > >What window is the background of main frame? > >How can I access the background of main frame? > **** The problems here stem from hiding the wrong window and then changing the parent. Neither of these are a correct solution, so telling you how to solve the problem when the basic approach is incorrect will not help. Instead, you must hide the parent frame of the view. I typically prefer to do this by creating a special child frame that implements user-defined messages, but you could simply do GetParentFrame() on the view to obtain it. But in all cases you should make sure you are hiding the window you intend to hide, not some other window. You should use Spy++ to study what windows exist and their relationship to each other. joe **** >thank for your helps. Joseph M.

You are doing something wrong here. Its not this complicated. You shouldnt have to change the parent of view to do this. GetParentFrame from view will get you to its parent cframewnd. You need to simply hide this after view has been attached to it. -- Ajay
