ACC1x: Microsoft Access Closes Abnormally from a Macro

ID: Q109366

The information in this article applies to:

SYMPTOMS

When Microsoft Access is unexpectedly closed by a macro, system resources are not released, and Microsoft Access remains in the Microsoft Windows Task List even though the application is no longer available.


CAUSE

The abnormal closing of Microsoft Access is due to event timing in the macro. The macro opens the Categories table, calls the Replace In Field dialog box, and then closes the Categories table. However, the Replace In Field dialog box, by design, functions differently than other dialog boxes do by allowing macros to continue running while the dialog box is displayed. Because the macro continues running the Categories table is closed before the replace action is completed. There is no macro action to pause the macro's execution; macro events occur sequentially unless a modal dialog box requests input from the user. The fact that the table is closed before the replace action is completed causes Microsoft Access to close abnormally.

When Microsoft Access closes abnormally in this way, it does not relinquish memory or system resources as it should.


STATUS

This problem no longer occurs in Microsoft Access version 2.0.
