Hides the visible balloon tooltip.
Syntax
rv = Send_Message(Ctrl, "OLE.HideBalloonTooltip")
Remarks
The HideBalloonTooltip method can be used to programmatically hide the currently visible balloon tooltip. There are no parameters. Since the control can only show one tooltip at a time, this method will know how to hide it.
Example
// Hide the balloon tooltip rv = Send_Message(@Window:".OLE_TREE", "OLE.HideBalloonTooltip")
