The Hide method hides the ToolTip for the specified Control if it is currently being displayed. It does not disable or otherwise prevent the same ToolTip from being displayed in the future. To instead disable all ToolTip windows associated with the current ToolTipTitle component, set the Active property to false.
Applications running in partial trust must assert the AllWindows permission to use this method, as Hide can hide the tip independent of user action.
