EditPoint.LessThan(TextPoint) EditPoint.LessThan(TextPoint) EditPoint.LessThan(TextPoint) Method

Definition

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

[System.Runtime.InteropServices.DispId(32)]
public bool LessThan (EnvDTE.TextPoint Point);
abstract member LessThan : EnvDTE.TextPoint -> bool
Public Function LessThan (Point As TextPoint) As Boolean
Parameters
Point
TextPoint TextPoint TextPoint

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

Returns

A Boolean value indicating true if Point has a greater AbsoluteCharOffset property value compared to the calling point object's AbsoluteCharOffset property.

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.
