Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

	IWin32Window window,
	Point point,
	int duration
)

Parameters

text
Type: System.String

A String containing the new ToolTip text.

window
Type: System.Windows.Forms.IWin32Window

The Control to display the ToolTip for.

point
Type: System.Drawing.Point

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

duration
Type: System.Int32

An Int32 containing the duration, in milliseconds, to display the ToolTip.

ExceptionCondition
ArgumentNullException

The window parameter is null.

ArgumentOutOfRangeException

duration is less than or equal to 0.

The pt parameter can specify a position outside the bounds of the associated control, its parent form, or even the desktop. The ToolTip is positioned in the center of the associated control. To display the ToolTip modally, call the Show(String, IWin32Window, Point) overloaded version of this method instead.

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.
