The Click event is generated when the user presses and
releases the mouse button anywhere over the control's window. To
distinguish between the user pressing the left or right mouse
buttons, use the MouseDown and MouseUp events. To
determine the column and row in the virtual display where the mouse
button was clicked, check the MouseX and MouseY
properties.
When debugging events, do not use message boxes to show when the
event occurred, as this will interfere with the normal functioning of
many events. For example, displaying a message box in the
Click event may prevent the DblClick event from being
raised.
