Attachment.OnMouseDown Property (Access)

Sets or returns the value of the On Mouse Down box in the Properties window. Read/write String.

Version Added: Access 2007

expression .OnMouseDown

expression A variable that represents an Attachment 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 MouseDown event occurs when the user clicks the mouse button while the mouse pointer rests over the object.

The OnMouseDown 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 Mouse Down 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 Mouse Down box is blank, the property value is an empty string.
