MDI operation on remaining child after on child closed?

I have a MDI app. If I have 3 or more child windows open at a time, and a close one off the 3 open windows, I want the remaining windows to automatically retile. A have a custom tile function in my CMainFrame and need to call it to reposition the remaining child windows. If I call this from the child I am closing, I get an ASSERTION because the child the calls reposition, is destroyed. I need to call this reposition AFTER the client is destroyed. I imagine I do this from CMainFrame but can not figure it out. All suggestions welcome and code samples greatly appreciated.

Check IsWindow(hWnd) before reposition

How do I know when to check IsWindow()against my reposition, from CMainFrame? Is there a member in CMainFrame that is called AFTER the Child is destroyed?

Try This

this is working , not to check IsWindow()

Add this code in ur CChildFrame Destructor

((CMDIFrameWnd*)AfxGetMainWnd())->MDITile(MDITILE_VERTICAL);

Hi,

Can U just post the code of how u r calling ur tile window function from child window? And if possible post the custom tile function also, so that we can get wher exactly it is crashing.
