SYMPTOMS

If you create an MFC AppWizard-generated ActiveX document container, insert a Microsoft Word document or Excel Spreadsheet, and move a toolbar from the top to the left side of the window, without dragging the toolbar through the main window, the toolbar will cover part of the document.

CAUSE

This problem is caused by CFrameWnd::RecalcLayout() not being called when the toolbar is docked on the left side of the frame window.

RESOLUTION

Force CFrameWnd::RecalcLayout() to be called from the OnShowControlBars() function of the COleDocObjectItem-derived class. Perform the following steps to do this:

Add the declaration of OnShowControlBars() to the COleDocObjectItem-derived class, which is declared in the Cntritem.h file:
```
	virtual BOOL OnShowControlBars(CFrameWnd*, BOOL);
					
```

Implement OnShowControlBars() of the COleDocObjectItem-derived class in theCntritem.cpp file:

BOOL CAXContainerCntrItem::OnShowControlBars(CFrameWnd* pFrameWnd, BOOL bShow)
{
	BOOL bResult = COleDocObjectItem::OnShowControlBars(pFrameWnd, bShow);
	
	if(pFrameWnd->m_nIdleFlags & CFrameWnd::idleLayout)
		pFrameWnd->RecalcLayout();

	return bResult;

}

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
