EditPoint.LessThan – metoda (TextPoint)

Vrátí zda hodnota nazývá EditPoint objektu AbsoluteCharOffset je menší než dané TextPoint objektu.

Obor názvů:  EnvDTE
Sestavení:  EnvDTE (v EnvDTE.dll)

Syntaxe

'Deklarace
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

Parametry

Vrácená hodnota

Typ: System.Boolean
Logická hodnota označující true li Point má větší AbsoluteCharOffset volající objekt point hodnotu vlastnosti AbsoluteCharOffset vlastnost.

Implementuje

TextPoint.LessThan(TextPoint)

Poznámky

LessThanVyvolá ArgumentException -li Point není v dokumentu jako volající bod objektu. S VirtualPoint objektu, LessThan porovná virtuální pozice, pokud je argument VirtualPoint. Jinak se porovnává "fyzických" pozice.

Příklady

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()
