Data Type

Description

Button

Required

Integer

The button that was released to trigger the event. If you need to test for the Button argument, you can use one of the following intrinsic constants as bit masks:

  • acLeftButton The bit mask for the left mouse button.

  • acRightButton The bit mask for the right mouse button.

  • acMiddleButton The bit mask for the middle mouse button.

Shift

Required

Integer

The state of the SHIFT, CTRL, and ALT keys when the button specified by the Button argument was pressed or released. If you need to test for the Shift argument, you can use one of the following intrinsic constants as bit masks:

  • acShiftMask The bit mask for the SHIFT key.

  • acCtrlMask The bit mask for the CTRL key.

  • acAltMask The bit mask for the ALT key.

X

Required

Single

The x coordinate for the current location of the mouse pointer, in twips.

Y

Required

Single

The y coordinate for the current location of the mouse pointer, in twips.

Remarks

  • The MouseUp event applies only to forms, form sections , and controls on a form, not controls on a report.

  • This event does not apply to a label attached to another control, such as the label for a text box. It applies only to "freestanding" labels. Pressing and releasing a mouse button in an attached label has the same effect as pressing and releasing the button in the associated control. The normal events for the control occur; no separate events occur for the attached label.

To run a macro or event procedure when these events occur, set the OnMouseUp property to the name of the macro or to [Event Procedure].

You can use a MouseUp event to specify what happens when a particular mouse button is pressed or released. Unlike the Click and DblClick events, the MouseUp event enables you to distinguish between the left, right, and middle mouse buttons. You can also write code for mouse-keyboard combinations that use the SHIFT, CTRL, and ALT keys.

To cause a MouseUp event for a form to occur, press the mouse button in a blank area or record selector on the form. To cause a MouseUp event for a form section to occur, press the mouse button in a blank area of the form section.

The following apply to MouseUp events:

  • If a mouse button is pressed while the pointer is over a form or control, that object receives all mouse events up to and including the last MouseUp event.

  • If mouse buttons are pressed in succession, the object that receives the mouse event after the first press receives all mouse events until all buttons are released.

To respond to an event caused by moving the mouse, you use a MouseMove event.
