註解Remarks

此屬性是很有用的以程式設計方式變更時觸發事件,Microsoft Access 所採取的動作。This property is helpful for programmatically changing the action that Microsoft Access takes when an event is triggered. 例如,在各個事件呼叫之間,您也許想要根據不同狀況下所引動的事件,來改變運算式的參數,或是從事件程序轉換到運算式或是巨集。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.

MouseMove 事件發生於使用者移動滑鼠經過物件。The MouseMove event occurs when the user moves the mouse over the object.

  • 如果您選擇 [運算式建立器],值會是 =運算式,其中_expression_是來自 [運算式建立器] 視窗的運算式。If you choose Expression Builder, the value will be =expression, where expression is the expression from the Expression Builder window.

  • 如果您選擇巨集建立器,值會是巨集的名稱。If you choose Macro Builder, the value is the name of the macro.

  • 如果您選擇程式碼建立器,值會是 [Event Procedure]。If you choose Code Builder, the value will be [Event Procedure].

如果 [On Mouse Move] 方塊是空白的,此屬性值為空字串。If the On Mouse Move box is blank, the property value is an empty string.
