abstract member GreaterThan : EnvDTE.TextPoint -> bool

Public Function GreaterThan (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 smaller AbsoluteCharOffset property value compared to the calling EditPoint object's AbsoluteCharOffset property; otherwise, false.

Implements

Remarks

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