Returns whether the value of the called EditPoint object's AbsoluteCharOffset is less than that of the given TextPoint object.

abstract member LessThan : EnvDTE.TextPoint -> bool

Public Function LessThan (Point As TextPoint) As Boolean

Parameters

Point: TextPoint

Required. A TextPoint to compare to the calling point object.

Returns

Boolean

true if Point has a greater AbsoluteCharOffset property value than the calling point object's AbsoluteCharOffset property; otherwise, false.

Implements

LessThan(TextPoint)

Attributes: DispIdAttribute

Remarks

LessThan throws a ArgumentException if Point is not in the same document as the calling point object. With the VirtualPoint object, LessThan compares the virtual positions if the argument is a VirtualPoint. Otherwise it compares the physical positions.
