 void Show(System::String ^ text, System::Windows::Forms::IWin32Window ^ window, int x, int y);

public void Show (string? text, System.Windows.Forms.IWin32Window window, int x, int y);

member this.Show : string * System.Windows.Forms.IWin32Window * int * int -> unit

Public Sub Show (text As String, window As IWin32Window, x As Integer, y As Integer)

Parameters

text

String

A String containing the new ToolTip text.

window

IWin32Window

The Control to display the ToolTip for.

x

Int32

The horizontal offset, in pixels, relative to the upper-left corner of the associated control window, to display the ToolTip.

Int32

The vertical offset, in pixels, relative to the upper-left corner of the associated control window, to display the ToolTip.

This version of the overloaded Show method operates identically to the Show(String, IWin32Window, Point) version, except that the offset is specified as separate x- and y-coordinates instead of a Point.

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.
