A Point containing the offset, in pixels, relative to the upper-left corner of the associated control window, to display the ToolTip.

Exception Condition

The window parameter is null.

The pt parameter can specify a position outside the bounds of the associated control, its parent form, or even the desktop. The version of the Show method displays the ToolTip for the specified control modally; that is, the ToolTip will be displayed until the Hide method is called, or until the parent form is minimized, hidden, or dismissed.

Applications running in partial trust must assert the AllWindows permission to use this method, as Show can control the display and location of a ToolTip independent of user action.


Requires AllWindows permission.
