Docking Toolbars Side-By-Side

Add the following method to your CMainFrame class:

void CMainFrame::DockControlBarLeftOf(CToolBar* Bar, CToolBar* LeftOf)
{
	CRect rect;
	DWORD dw;
	UINT n;
	
	// get MFC to adjust the dimensions of all docked ToolBars
	// so that GetWindowRect will be accurate
	RecalcLayout(TRUE);
	
	LeftOf->GetWindowRect(&rect);
	rect.OffsetRect(1,0);
	dw=LeftOf->GetBarStyle();
	n = 0;
	n = (dw&CBRS_ALIGN_TOP) ? AFX_IDW_DOCKBAR_TOP : n;
	n = (dw&CBRS_ALIGN_BOTTOM && n==0) ? AFX_IDW_DOCKBAR_BOTTOM : n;
	n = (dw&CBRS_ALIGN_LEFT && n==0) ? AFX_IDW_DOCKBAR_LEFT : n;
	n = (dw&CBRS_ALIGN_RIGHT && n==0) ? AFX_IDW_DOCKBAR_RIGHT : n;
	
	// When we take the default parameters on rect, DockControlBar will dock
	// each Toolbar on a seperate line. By calculating a rectangle, we
	// are simulating a Toolbar being dragged to that location and docked.
	DockControlBar(Bar,n,&rect);
}

Now, in your CMainFrame::OnCreate, instead of using DockControlBar, use DockControlBarLeftOf:

	m_wndToolBar1.EnableDocking(CBRS_ALIGN_ANY);
	m_wndToolBar2.EnableDocking(CBRS_ALIGN_ANY);
	EnableDocking(CBRS_ALIGN_ANY);
	DockControlBar(&m_wndToolBar1);
	DockControlBarLeftOf(&m_wndToolBar2,&m_wndToolBar1);
