Call this member function to compute the required size of the window rectangle based on the desired client-rectangle size.

virtual void CalcWindowRect(
   LPRECT lpClientRect,
      UINT nAdjustType = adjustBorder 



Points to a RECT structure or CRect object that contains the resultant value of the window rectangle.


An enumerated type used for in-place editing. It can have the following values: CWnd::adjustBorder = 0, which means that scroll-bar sizes are ignored in calculation; and CWnd::adjustOutside = 1, which means that they are added into the final measurements of the rectangle.

A client rectangle is the smallest rectangle that completely encloses a client area. A window rectangle is the smallest rectangle that completely encloses the window.

// Uses CalcWindowRect to determine size for new CFrameWnd
// based on the size of the current view. The end result is a
// top level frame window of the same size as CMyView's frame.
void CMyView::OnMyCreateframe() 
   CFrameWnd* pFrameWnd = new CFrameWnd;
   CRect myRect;
   pFrameWnd->Create(NULL, "My Frame");
   pFrameWnd->CalcWindowRect(&myRect, CWnd::adjustBorder);
   pFrameWnd->MoveWindow(0, 0, myRect.Width(), myRect.Height());
