FIX: 'Read-Only' Warning When Adding an MFC Class From a Type Library

• Type the location of the type library that you want to use directly into the Location text box, rather than browsing to the file. The problem is with the code that uses the dialog box for the Browse operation, and not the actual import. -or-
  
  
• Make sure that the type library from which you need to add classes is already registered, and then add the class from the registry instead of from a file. To do this, follow these steps:
  1. On the Project menu, select Add Class.
  2. Select MFC Class from Typelib from the list of templates.
  3. For Add Class from, select Registry.
  4. In the list of available type libraries, find the friendly name for the type library from which you want to add classes.
  5. From the list of interfaces in that type library, select the classes for which you want to add wrappers.
  6. Click Finish.
  -or-
  
  
• Change the file permissions for the type library so that the file is not marked Read-Only. The Add Class From TypeLib Wizard does not actually change the type library. This workaround may be useful in cases in which it is not feasible to register the type library. Note, however, that modifying file permissions can leave the type library open to accidental changes, and should be done carefully.
