FIX: LoadBarState() Causes Assert In Bardock.cpp, Line 682 (151382)
The information in this article applies to:
- Microsoft Visual C++ 4.0
- Microsoft Visual C++ 4.1
- Microsoft Foundation Classes (MFC)
This article was previously published under Q151382 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.
