EditPoint.LessThan Method

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

Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

Syntax

'Declaration
Function LessThan ( _
    Point As TextPoint _
) As Boolean

bool LessThan(
    TextPoint Point
)

bool LessThan(
    [InAttribute] TextPoint^ Point
)

abstract LessThan : 
        Point:TextPoint -> bool 

function LessThan(
    Point : TextPoint
) : boolean

Parameters

• Point
  Type: EnvDTE.TextPoint
  Required. A TextPoint to compare to the calling point object.

Return Value

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

Implements

TextPoint.LessThan(TextPoint)

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.

Examples

Sub LessThanExample(ByVal dte As DTE)

    ' Create a new text file.
    dte.ItemOperations.NewFile()
    Dim txtDoc As TextDocument = _
        CType(dte.ActiveDocument.Object(), TextDocument)

    ' Create an edit point at the empty text document's StartPoint 
    ' and EndPoint; CompareEditPoints displays "point1 and point2
    ' occupy the same location."
    Dim point1 As EditPoint = txtDoc.StartPoint.CreateEditPoint()
    Dim point2 As EditPoint = txtDoc.EndPoint.CreateEditPoint()
    CompareEditPoints(point1, point2)

    ' Insert ten lines of text.
    Dim i As Integer
    For i = 1 To 10
        point1.Insert("Line " & i.ToString() & vbCrLf)
    Next

    ' Create an edit point at the text document's StartPoint and 
    ' EndPoint; CompareEditPoints displays "point1 comes before point2."
    point1 = txtDoc.StartPoint.CreateEditPoint()
    point2 = txtDoc.EndPoint.CreateEditPoint()
