EditPoint2.LessThan-Methode (TextPoint)

Gibt zurück, ob der Wert von AbsoluteCharOffset des aufgerufenen EditPoint-Objekts größer ist als der des angegebenen TextPoint-Objekts.

Namespace:  EnvDTE80
Assembly:  EnvDTE80 (in EnvDTE80.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

Parameter

Rückgabewert

Typ: System.Boolean
true , wenn Point einen AbsoluteCharOffset-Eigenschaftswert aufweist, der größer als die AbsoluteCharOffset-Eigenschaft des aufrufenden Point-Objekts ist; andernfalls false.

Hinweise

LessThan löst eine ArgumentException aus, wenn sich Point nicht im selben Dokument wie das aufrufende Point-Objekt befindet.Mit dem VirtualPoint-Objekt vergleicht LessThan die virtuellen Positionen, wenn das Argument ein VirtualPoint ist.Andernfalls vergleicht es die physikalischen Positionen.

Beispiele

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
