WD97: Problems with AutoExec Macro That Calls Macro in Add- in

ID: Q181536

The information in this article applies to:

Microsoft Word 97 for Windows

SYMPTOMS

If you have an AutoExec macro designed to work with an add-in program, Word will return an error that is based on the task the AutoExec macro is attempting to complete. For example, attempting to call a macro stored in an add-in template results in the following error:

Run-time error '4633': Unable to run the specified macro.

CAUSE

By design, Visual Basic for Applications is asynchronous in operation. This means that while one command is processing, dependent upon the command called, your macro will begin processing the next command.

For example, if your code processes a command to print a document, and the next command displays a message box, the message box appears before the document completes printing. In Word, an AutoExec macro is run before any add-ins are loaded; therefore, the call to the macro stored in your add-in fails and an error occurs.

The following sample macro commands provide a means for working around this limitation by using the OnTime method to delay processing of a macro stored in a template add-in.

The When argument of the OnTime method specifies the time at which a macro is to be run. It can be a string that specifies a time (for example, "4:30 pm" or "16:30"), or it can be a serial number returned by a function, such as TimeValue or TimeSerial (for example, TimeValue("2:30 pm") or TimeSerial(14, 30, 00)). You can also include the date (for example, "6/30 4:15 pm" or TimeValue("6/30 4:15 pm")).

Use the sum of the return values of the Now function and either the TimeValue or TimeSerial function to set a timer to run a macro a specified amount of time after the statement is run. For example, use Now+TimeValue("00:05:30") to run a macro 5 minutes and 30 seconds after the statement is run.

The Tolerance argument of the OnTime method specifies the maximum time (in seconds) that can elapse before a macro that wasn't run at the time specified by When is canceled. Macros may not always run at the specified time. For example, if a sort operation is under way or a dialog box is being displayed, the macro will be delayed until Word has completed the task. If this argument is 0 (zero) or omitted, the macro is run regardless of how much time has elapsed since the time specified by When.

NOTE: The time to wait will vary between faster and slower computers and may need to be adjusted appropriately.


   Application.OnTime When:=Now() + TimeValue("00:00:3"), _
       Name:="MyProject.MyModule.MyMacro", Tolerance:=2
