Form.OnActivate property (Access)

  • Article

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

Syntax

expression.OnActivate

expression A variable that represents a Form object.

Remarks

This property is helpful for programmatically changing the action that 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 Activate event occurs when the form or report receives the focus and becomes the active window.

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

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

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

  • If you choose Code Builder, the value will be [Event Procedure].

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

Example

The following example associates the Activate event with the macro Activate_Macro for the Order Entry form.

Forms("Order Entry").OnActivate = "Activate_Macro"
