Retrieves an array of disjoint text ranges from a text container where each text range begins with the first partially visible line through to the end of the last partially visible line.
Assembly: UIAutomationClient (in UIAutomationClient.dll)
Disjoint text ranges may occur when any content of a text container is obscured by an overlapping window or other object, or when a text container with a multi-column layout has one or more columns partially scrolled out of view.
If no text is visible, a degenerate (empty) text range is returned. This empty range can be returned if the text container is empty or when all text is scrolled out of view.
- Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
