Sets or returns the value of the On Open box in the Properties window of a form or report. Read/write String.

Syntax

expression. OnOpen

expression A variable that represents a Report object.

Remarks

This property is helpful for programmatically changing the action Microsoft Access takes when an event is triggered. For example, between event calls you may want to change an expression's parameters, or switch from an event procedure to an expression or macro, depending on the circumstances under which the event was triggered.

The Open event occurs when a form is opened, but before the first record is displayed. For reports, the event occurs before a report is previewed or printed.

The OnOpen value will be one of the following, depending on the selection chosen in the Choose Builder window (accessed by clicking the Build button next to the On Open box in the object's Properties window):

  • If Expression Builder is chosen, the value will be "= expression", where expression is the expression from the Expression Builder window.

  • If Macro Builder is chosen, the value is the name of the macro.

  • If Code Builder is chosen, the value will be "[Event Procedure]".

If the On Open box is blank, the property value is an empty string.
