ToolTip.Show Method (String, IWin32Window)
Assembly: System.Windows.Forms (in system.windows.forms.dll)
A String containing the new ToolTip text.
The Control to display the ToolTip for.
The window parameter is a null reference (Nothing in Visual Basic).
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 closed. The ToolTip is positioned in the center of the associated control.
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.
