Raised Window Border

Environment: VC++ 4.1, Windows 95

I want to have a CTreeCtrl with a raised border like the one used by 
VC++ 4.1 project window.  Here is what I've tried:

1 - Use the WS_THICKFRAME style when I create the CTreeCtrl but this 
does not produce quite the same raised border (it's missing the 
top-left inside dark line) and lets the user resize the ctrl which I do 
not want.

2 - Implemented CMiniFrameWnd window around the CTreeCtrl with a 
MFS_4THICKFRAME style, but this too does not create the correct raised 
border.

3- Implemented OnNcPaint() and OnNcCalcSize() for my subclass of 
CTreeCtrl.  This code comes close (it's a little thin) to producing the 
correct raised border but does not allow scroll bars.  This code is 
shown below:

void CProjectView::OnNcPaint() 
{
	CWindowDC dc(this);
	CRect rect;
	GetWindowRect(&rect);
	rect.OffsetRect(-rect.left, -rect.top);

	dc.Draw3dRect(rect, afxData.clrBtnHilite, 
afxData.clrWindowFrame);

	if (afxData.bWin4)
	{
		rect.InflateRect(-CX_BORDER, -CY_BORDER);
		dc.Draw3dRect(rect, afxData.clrBtnFace, 
afxData.clrBtnFace);
		rect.InflateRect(-CX_BORDER, -CY_BORDER);
		dc.Draw3dRect(rect, afxData.clrWindowFrame , 
afxData.clrBtnShadow);
	}
}

void CProjectView::OnNcCalcSize(BOOL bCalcValidRects, NCCALCSIZE_PARAMS 
FAR* lpncsp) 
{
	if (afxData.bWin4)
	{
		::InflateRect(lpncsp->rgrc,
			-(CX_BORDER * 3), -(CY_BORDER * 3));
	}
	else
	{
		::InflateRect(lpncsp->rgrc,
			-CX_BORDER, -CY_BORDER);
	}
}

Any suggestions?

Yes, just add the WS_EX_DLGMODALFRAME | WS_EX_CLIENTEDGE extended styles =
to the tree control and you will get the effect you are looking for.

looks to me like a combination of Client Edge and Modal Frame - both
settable in the Resource Editor
