BUG: IDE Hangs Bringing Up Class Wizard While Debugging

The information in this article applies to:

• The Visual Workbench Integrated Debugger, included with: Microsoft Visual C++ for Windows, versions 1.5 and 1.51

SYMPTOMS

If you try to start Class Wizard during a hard-mode debugging in the Microsoft Visual Workbench integrated debugger, a blank dialog box may appear and the Visual Workbench may hang.

NOTE: This problem does not occur when debugging in soft mode. As a result, this problem does not occur under Windows NT, because Windows NT does not support hard-mode debugging.

RESOLUTION

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This is not a problem in Visual C++, 32-bit Edition. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

To reproduce this problem, perform the following steps:

1. Create a project using AppWizard, enabling all options except "external makefile".

2. Build a debug version.

3. In the Options menu, choose Debug; select "Hard Mode" from the Debug dialog box.

4. Use the toolbar or press F8 to single step to the start of WinMain.

5. Start Class Wizard. A blank dialog comes up and the system hangs.
