It's not the first time I see that article of Paul DiLascia. His ideeas are nice, just one problem they don't work in my implementation. Anyway, there's something wrong with the article, the author wonders about the undocumented wParam = 1 (in WM_NCPAINT), while the MSDN clearly states it stands for "entire NC area needs repainting".

As about your code, first of all thank you for your effort.
Basically you're doing what I'm doing, just my code doesn't work.

Did you test it with VS 2008 ?

I tried to browse the MFC sources, it's a brand new world, there's no more WindowProc with message loop. Lots of ATL code.

My code follows:
void CMainFrame::OnNcPaint()
{
	const MSG* pMsg = GetCurrentMessage();

	CRgn rgnWnd, rgnCli, rgnMenu;
	int iMenuHeight = GetSystemMetrics(SM_CYMENU); //height of the menu bar

	// Compute the NC region as a difference between the window rect and client rect.
	// The region must be relative to top left corner of the window
	CRect rcWnd, rcCli;
	// Get the window rect (relative to the top-left corner of the window)
	GetWindowRect(&rcWnd);
	CPoint ptOffset = - rcWnd.TopLeft();
	rcWnd.OffsetRect(ptOffset);

	// Get the client rect (relative to the top-left corner of the window)
	GetClientRect(&rcCli);
	ClientToScreen(rcCli);
	rcCli.OffsetRect(ptOffset);
	
	// Include de menu bar in the client area
	rcCli.top -= iMenuHeight;

	// Create regions for the window rect and client rect
	rgnWnd.CreateRectRgn(rcWnd.left, rcWnd.top ,rcWnd.right ,rcWnd.bottom);
	rgnCli.CreateRectRgn(rcCli.left, rcCli.top ,rcCli.right ,rcCli.bottom);
	
	// Obtain their difference (that will be the entire non client area without the menu bar)
	rgnWnd.CombineRgn(&rgnWnd, &rgnCli, RGN_DIFF);

	// Create a region for the menu bar
	rgnMenu.CreateRectRgn(rcCli.left, rcCli.top, rcCli.right, rcCli.top + iMenuHeight);

	if(pMsg->wParam != 1) // Is only a part of the nc area requiring repaint ?
	{ // If it's so:
		// Get the region requiring painting:
		CRgn r;
		r.CreateRectRgn(0,0,0,0);
		r.CopyRgn(CRgn::FromHandle((HRGN) pMsg->wParam));
		r.OffsetRgn(ptOffset); // Screen coordinates need to be transformed to window coordinates
		
		// Intersect with the NC area without the menu bar:
		rgnWnd.CombineRgn(&rgnWnd, &r, RGN_AND);
		
		// Intersect with the menu bar:
		rgnMenu.CombineRgn(&rgnMenu, &r, RGN_AND);
	}

	// Paint the nonclient area without the menu bar:
	CWindowDC dc(this);
	CBrush brush;
	brush.CreateSolidBrush(RGB( 255, 0, 0 ));
	dc.FillRgn(&rgnWnd, &brush);

	// Paint the menu bar:
	CRect rcBox;
	rgnMenu.GetRgnBox(&rcBox);
	if(!rcBox.IsRectEmpty()) // Make sure the region is not empty
		::DefWindowProc(m_hWnd, WM_NCPAINT, (WPARAM) rgnMenu.m_hObject, 0); // has no effect
}
