strange debugging problem 1

[peterworth]

hi,

i'm trying to figure out why a debug assertion keeps on failing in my program. it's in the initinstance funcrion of an mfc wizard created app:

pMainFrame->ShowWindow(m_nCmdShow);
ASSERT:IsWindow(pMainFrame->m_hWnd));
pMainFrame->UpdateWindow();

the assert above does NOT fail, but when updatewindow is called immediately after, it goes here:

_AFXWIN_INLINE void CWnd::UpdateWindow()
{ ASSERT:IsWindow(m_hWnd)); ::UpdateWindow(m_hWnd); }

and this assertion fails, despite being (as far as i can see) identical to the previous assertion.

i'd be very grateful if anyone can point out why this happens, thanks.

Is your window being subclassed anywhere? step all the way through the code to make sure that is the hWnd it's referring to; look at the pMainFrame's hWnd and look at the value of the other to see if they're the same.
