FIX: Rebuilding .CLW File Does Not Restore Link to ODL File

ID: Q135049

The information in this article applies to:

Microsoft Visual C++ 32-bit Edition, versions 2.0, 2.1

SYMPTOMS

A project's Object Description Language (ODL) file is not updated when new automation properties and methods are added using ClassWizard. The project's ClassWizard (.clw) file has been deleted and rebuilt prior to the occurrence of this behavior. All properties and methods added before the rebuilding of the ClassWizard file are still correctly listed in the ODL file.

CAUSE

When the .clw file is rebuilt by the development environment, the ODLFile= keyword line is not added to the new file.

RESOLUTION

The ODLFile= entry must be manually added to the .clw file so that ClassWizard can add properties and methods to the ODL file. The ODLFile= entry can be added by using the development environment editor or Notepad.

Manually adding the ODLFile= entry will not automatically update the ODL file to bring it back in synch with ClassWizard. Any properties and methods that were added via ClassWizard while the ODLFile= entry was missing from the .clw file must be either manually added to the ODL file or removed and then added again by using the ClassWizard.

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 2.2 for Windows NT.

MORE INFORMATION

An example of the ODLFile= line can be found in the .clw file provided with the AutoClik sample. In this sample, the [General Info] section of the Autoclik.clw file includes the following line:


   ODLFile=autoclik.odl

ClassWizard uses this reference to a specific ODL to determine the file to update when new properties and methods are added. When the .clw file is rebuilt using the ClassWizard option from the development environment Resource Editor, the ODLFile= reference line is not included in the newly built .clw file. After the rebuild, ClassWizard does not issue a warning when adding new properties and methods to the new .clw file even though the changes are not reflected in the ODL file.

This problem does not appear in Visual C++ version 4.0. Visual C++ 4.0 does not use a keyword in the .clw file to keep track of the name of the ODL file.
