ACC: UndoCurrentRecord in BeforeUpdate Property Causes Error

• Microsoft Access versions 1.0, 1.1, 2.0

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

If you create a macro that contains a DoMenuItem action that chooses Undo Current Record from the Edit menu, and you run the macro from a form's BeforeUpdate property, you may receive the following error message when you edit data in the form:

   Command not available: UndoCurrentRecord.

CAUSE

The Undo Current Record command is not available for use with a macro run from a form's BeforeUpdate property.

STATUS

This behavior no longer occurs in Microsoft Access version 7.0.

RESOLUTION

In your macro, enter CancelEvent as the first action, and then follow that with the SendKeys action to send an ESC key. (This has the same effect as choosing the Undo Current Field command from the Edit menu.)

MORE INFORMATION

Page 48 of the Microsoft Access "Language Reference," versions 1.0 and 1.1, discusses uses for this type of macro in the BeforeUpdate property, and indicates that calling Undo Current Record works correctly in such a macro. This is not the case. Calling Undo Current Record causes the error message above and should not be used.
