A degenerate range nearest the specified location. Null is never returned.

}

Remarks

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

Because hidden text is not ignored by RangeFromPoint, a degenerate range from the visible text closest to the given point is returned.
