SYMPTOMS
If you have an AutoExec macro designed to work with an add-in program, Word
returns an error message 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 message:
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 begins 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.
WORKAROUND
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.
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 is 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 varies between faster and slower computers and may need to be adjusted appropriately.
