)

Parameters

The location, in screen coordinates.

Return Value

Type: System.Windows.Automation.Provider.ITextRangeProvider
A degenerate range nearest the specified location. This method never returns nulla null reference (Nothing in Visual Basic).

Remarks

A text range that encloses a child object is returned if the screen coordinates are within the coordinates of an image, hyperlink, or other embedded object.

Because hidden text is not ignored by RangeFromPoint, this method returns a degenerate range from the visible text that is nearest the specified point.
