|Access Developer Reference|
expression A variable that represents a Form object.
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 Timer event occurs for a form at regular intervals as specified by the form's TimerInterval property.
The OnTimer 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 Timer box in the form'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 Timer box is blank, the property value is an empty string.
The following example prints the value of the OnTimer property in the Immediate window for the "Order Entry" form.
