property Button.Mode as ModeEnum
Specifies the control's mode.

TypeDescription
ModeEnum A ModeEnum expression that indicates how the button's state is changed when the user clicks the button. 
By default, the control's Mode property is exButton. The State property is changed by the control depending on the control's Mode property. Use the Style or Skin property to change the visual appearance for the button. The control fires the Click event when user clicks the button.  The control fires also the Click event if the button has the focus, and the user releases the SPACE key. Use the KeyDown event to avoid firing the Click event when user presses the SPACE key like in the following sample:
Private Sub Button1_KeyDown(KeyCode As Integer, Shift As Integer)
    KeyCode = 0
End Sub
