FIX: ResizeParentToFit Doesn't Work in SDI CFormViews

The information in this article applies to:

• The Microsoft Foundation Classes (MFC), included with: Microsoft Visual C++ for Windows, version 1.0

SYMPTOMS

Calling CScrollView::ResizeParentToFit(TRUE) in a CFormView's OnInitialUpdate() to let the size of the view dictate the size of its frame window causes the frame window to become greatly enlarged.

CAUSE

Because the view window has not yet been displayed, ResizeParentToFit(TRUE) uses the size of the CFormView. The CFormView is created with size CRect(0,0,0,0), and therefore the view size is miscalculated and a rather large window is created.

RESOLUTION

Be sure to call GetParentFrame()->RecalcLayout() to set the view window's size correctly before calling ReSizeParentToFit(TRUE). For additional information, please see the following article(s) in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed this to be a problem in the Microsoft Foundation Class Libraries version 2.0. This problem was corrected in the Microsoft Foundation Class Libraries version 2.5.
