BUG: ATL Object Wizard Prevents Undo Changes

• Microsoft Active Template Library, version 2.1

SYMPTOMS

When using the Active Template Library (ATL) Object Wizard to add an object to the ATL project, you might get a message box informing you that the .idl and Stdafx.cpp files were modified outside the editor.

If you have edited the file, the work is saved before the wizard changes the source. One bad side-effect of reloading is that the user cannot undo any changes previous to the reload.

This mean that if you delete code, then run the ATL object wizard, there is no way to get back to the original file using undo, and your original file is lost.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
