FIX: Can't Get to Hidden Workspace After Enabling Docking View

• Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1, 4.2

SYMPTOMS

The Project Workspace window is not accessible from the toolbar, toolbar context menu, View menu, or the keyboard ViewWorkspaceWindow command (ALT+0). Trying to gain access to the workspace by using one of these methods causes an illegal operation in MSDEV.EXE.

On Windows 95 the error reads:

   This program has performed an illegal operation and will be shut
   down.

On Windows NT version 3.51, the error reads:

   An application error has occurred

   MSDEV.EXE
   Exception: access violation (0x00000005), Address: 0x50012861

RESOLUTION

To work around this problem, do not enable docking view for the Project Workspace window while it is hidden.

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++ version 5.0.
