Keeping ClassWizard Updated When Code Changes
As your program develops, it's very likely that you'll need to delete or modify classes, delete or add resources, or move a class from one source file to another. ClassWizard will track your code as you make these changes: it asks you for the updated information when you next edit the affected class.
ClassWizard stores the information about your project's classes in a file with the file extension .clw. To accommodate source files that have changed, ClassWizard displays the Repair Class Information dialog box whenever it finds that the information in the .clw file is out of date.
The Repair Class Information dialog box has two main functions:
Deleting obsolete classes from the ClassWizard file
Updating the ClassWizard file with the new name or location of classes that you have changed or moved
