SYMPTOMS
An assert can occur in bardock.cpp, line 682 when CFrameWnd::LoadBarState is called. This behavior occurs if SaveBarState was previously called and more than one CToolBar was docked at the bottom of the window.



CAUSE
The assert occurs because CFrameWnd::EnableDocking was called prior to creation of the CToolBars.



RESOLUTION
The assertion is unnecessary and can be ignored. To avoid the assertion, make sure that CFrameWnd::EnableDocking is called after all calls to CToolBar::Create.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ 32- bit Edition version 4.2.



MORE INFORMATION
In Visual C++ 4.0, the assertion occurs in bardock.cpp, line 657.

MFC maintains a CPtrArray of CControlBars. The validity of the CPtrArray is checked when LoadBarState is called. There are cases where the CPtrArray is not initialized at this juncture but is initialized correctly later on. Therefore, the assert is unnecessary.
