Copying from my answer above:

In my project, I had a CScrollView as MainView and then the possibility to hold a CFormView for EVERY element on the screen (up to 48). All secondary views should close without problems and /or asking to save changes on the document. I managed it with:

BOOL CMyDoc::CanCloseFrame(CFrameWnd* pFrame)
{	int nError = 0;

	//Closing the active window
	CView* pFrmView = pFrame->GetActiveView ();
	if (pFrmView->IsKindOf (RUNTIME_CLASS (CFormView)))
		return TRUE;

	//Closing automatically all secondary windows when the main one is closed by the user
	POSITION pos = GetFirstViewPosition ();	while (pos)
	{	CView* pView = GetNextView (pos);
		if (pView->IsKindOf (RUNTIME_CLASS (CFormView)))
		{	CFrameWnd* pTempFrame = pView->GetParentFrame ();
			if (pTempFrame)
				pTempFrame->DestroyWindow ();
		}
	}

	//Asking to save changes and so on.
	return CDocument::CanCloseFrame(pFrame);
}


Then I only have coded the OnDestroy in every secondary window to release all used memory and delete contents of listboxes, array and so on.

About the process of creating other windows... I have answered it as well in many times. Take a look with the search option in the forum (not in the articles) with my nick. It is quite good explained.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
