Form.OnError Property (Access)
Sets or returns the value of the OnError box in the Properties window of a form or report. Read/write String.
Syntax
expression .OnError
expression A variable that represents a Form 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 Error event occurs when a run-time error is produced in Microsoft Access when a form or report has the focus. This includes Microsoft Jet database engine errors, but not run-time errors in Visual Basic.
The OnError 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 OnError 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 OnError box is blank, the property value is an empty string.
Example
The following example associates the Error event with the macro "Error_Handler_Macro" for the "Order Entry" form.
Forms("Order Entry").OnError = "Error_Handler_Macro"
