PRB: "Cannot Access the ClassView Information File..."

 Last reviewed: February 25, 1998
Article ID: Q181719
The information in this article applies to:
  • Microsoft Visual SourceSafe, 32-bit, for Windows, version 5.0
  • Microsoft Visual Studio 97

SYMPTOMS

When opening a source-code controlled, Visual C++ project workspace, you receive following the message: 

   Cannot access the ClassView information file. ClassView information will
   not be available.

CAUSE

The Visual C++ project's "No Compile Browser" file, or .ncb file, is marked as read-only.

RESOLUTION

Changing the read-only attribute of the <prjname>.ncb to read/write is the only step necessary to resolve this problem.

NOTE: The most common reason the .ncb file would be marked read-only in the first place is because the file was manually added to Visual SourceSafe (VSS). This file was never intended to be placed under source control and will need to be removed (destroyed) from the project within the VSS Explorer. Otherwise, VSS may change the file attribute back to read-only.

STATUS

This behavior is by design.

MORE INFORMATION

The .ncb file contains information generated by the parser that is used by ClassView, WizardBar, and Component Gallery. If this file is accidentally or deliberately deleted, it is automatically regenerated.

Steps to Reproduce Behavior

  1. Open Microsoft Developer Studio and from the File menu, click New.

  2. From the Projects tab, create a new Visual C++ project using the Microsoft Foundation Class (MFC) AppWizard (.dll) in a new workspace.

  3. Close the workspace.

  4. Open the Visual SourceSafe Explorer.

  5. Add the Visual C++ project to Visual SourceSafe (VSS) by using a drag- and-drop operation to move the project's directory from Windows Explorer onto the root project ($/) in the VSS Explorer.

  6. Now that the project has been added to Visual SourceSafe, all the project files should be marked read-only.

  7. Reopen the workspace in Developer Studio.
