WD98: How Word Converts Execute-Only Macros

• Microsoft Word 98 Macintosh Edition

SUMMARY

In earlier versions of Word, WordBasic macro code can be hidden with the MacroCopy command. This command makes a macro "execute-only." In this state, the macro code cannot be viewed, but the macro can be run.

This technique is useful if you are distributing macro solutions to customers or to coworkers, and you do not want the customers or coworkers to be able to modify the macros. This design means that some macros in the template can be "execute-only" while others remain viewable.

In the versions of Word listed at the beginning of this article, you can protect only an entire project (that is, all of the code within a template or document must be either locked or unlocked). When a project is locked, any Visual Basic for Applications code within the template cannot be viewed.

The "More Information" section of this article discusses how templates containing "execute-only" macros that were created in earlier versions of Word are converted.

MORE INFORMATION

Templates containing execute-only macros are converted differently depending on whether these execute-only macros are in the Normal template (Normal.dot) or a custom template.

Execute-Only Macros in Normal.dot

Word will convert the Normal template (ordinarily the first time Word is started after you upgrade to Word 98 or later) and will not convert any of the execute-only macros. A backup copy of the original Normal template will be saved with a default file name of "Backup of Normal" in the same directory or folder where the Normal template is located. This allows Word 98 and later versions of the Normal template to be unprotected; you can record new macros and have all the typical programming functionality that Word allows.

NOTE: The "Backup of Normal" file is only created the first time Word is run. If, after starting Word, you replace the Normal template file with an earlier version of the Word Normal template file, the backup file will not be created.

Execute-Only Macros in a Custom Template

When any template other than the Normal template is converted, all execute- only macros remain in the template, and the entire template or project is locked (you cannot edit code in it). This design means that custom solutions will still work and the code will still be protected. A disadvantage is that formerly-accessible macros may no longer be accessible.

You will receive the "Project is unviewable" message when you attempt to do any of the following:

• Edit a converted execute-only macro.

      -or-
  

• View the project contents in the Visual Basic Editor Project Explorer.

      -or-
  

• View the project properties in the Visual Basic Editor Project Explorer.

• Access the original template in the earlier version of Word.

      -or-
  

• In the earlier version of Word, remove all of the execute-only macros so Word will not protect the project during the conversion process.
