CDockBar background color?

[mega Kluge]

I have a legacy Visual Studio 6.0 application. I need to change the color of the Dockbar (as illustrated in the attached picture). I have tried the implementation found here to no effect.

I'm not having much luck in my internet search endeavors.

Basically, can't I grab a dockbar (top, bottom, left, etc...) at paint (or in CMainFrame::OnNotify) time like: (where m_BrushDocBar is my initialized brush of my preferred color.)??

	
       CControlBar* pTopDockBar = GetControlBar(AFX_IDW_DOCKBAR_TOP);
	if (pTopDockBar != NULL)
	{
		SetClassLong(pTopDockBar->m_hWnd, GCL_HBRBACKGROUND, (LONG)m_BrushDocBar.GetSafeHandle());
	}

I'd really appreciate any pointers on how to accomplish this. Thanks.

Edit: I tried the code below in CMainFrame::OnCreate. No effect

CControlBar* pTopDockBar = GetControlBar(AFX_IDW_DOCKBAR_TOP);
	HWND hBar = pTopDockBar->GetSafeHwnd();
	::SetClassLongPtr(
		hBar,
		GCLP_HBRBACKGROUND,
		(LONG_PTR)GetSysColorBrush(COLOR_ACTIVECAPTION));
