MDIClWnd.cpp -- a child class window that fills itself with a
MDIClWnd.h			stretched bitmap


/////////////////////////////////////////////////////////////////////
// Modify Mainframe Class.

// 1) embed MDIClientWnd class in this class.
	CMDIClientWnd m_wndMDIClient;

// 2) subclass MDIClientWnd window in WM_CREATE handler
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CMDIFrameWnd::OnCreate(lpCreateStruct) == -1)
		return -1;

	// subclass our CMDIClientWnd class to MDIClient window
	if( !m_wndMDIClient.SubclassWindow( m_hWndMDIClient))
	{
		TRACE( " Failed to subclass MDI client window\n");
		return -1;
	}

	
// 3) use ClassWizard to add a WM_SIZE handler where you invalidate
// the MDIClientWnd window
void CMainFrame::OnSize(UINT nType, int cx, int cy) 
{
	CMDIFrameWnd::OnSize(nType, cx, cy);
	
	m_wndMDIClient.Invalidate();
}
