A Real AutoSave in WordBasic

Word has a built-in AutoSave feature that offers a limited amount of protection for the documents on which you are working. If you have AutoSave turned on, Word periodically (you can define how often) saves a copy of the document on which you are working. These periodic saves are stored in special backup files that Word maintains; it does not store them in the same document as the one on which you are working.

For instance, let's say you are working on a document named Report.doc, and that you have AutoSave enabled and set for every ten minutes. When the ten-minute mark is reached, Word stores the document in a temporary file, not back in Report.doc. The only time that this happens is when you explicitly save the file (by clicking on the Save button). Then Report.doc is saved and the temporary file is deleted. When you first start Word, it checks to see if any of these temporary files are on your system. If they are, then it "recovers" those files and gives you the chance to save them, if you desire.

There may be times when you want a real AutoSave instead of one that uses temporary files. For instance, you might want Report.doc saved every ten minutes--automatically. To do this, you need to create your own macros that take care of it for you. A series of three simple macros will accomplish the task. The first macro, AutoOpen, looks like this:

Sub MAIN
   WaitAutoSave
End Sub

This macro automatically runs the second macro, WordSave, which looks like this:

Sub MAIN
   OnTime Now+ TimeValue("00:10:00"), "Saver"
End Sub

This macro runs another macro in ten minutes called Saver. This is the macro that actually does the work; it looks like this:

Sub MAIN
     FileSave
     WordSave
End Sub

If you save these macros with a document, then they will always provide an AutoSave for that document. The AutoOpen macro is run when the document is first opened, and it runs WordSaver. WordSaver does nothing but run the Saver macro after ten minutes has elapsed. When Saver runs, it saves the active document, and then runs WordSaver again, which starts the ten-minute cycle all over.

There are a couple of drawbacks to these macros. First of all, there is no way to undo what is saved. With the regular Word AutoSave, you can always close a document without saving any modifications. The second drawback is that these macros will save whichever document is currently active--including one you might not have intended to save. Finally, if you save these macros as part of a template, then when you open a document using that template, ten minutes later a Save As dialog box will appear since your new document is not yet named.
