Artigo
10/26/2012

Retorna se o valor da propriedade de AbsoluteCharOffset do objeto de EditPoint é maior do que o do objeto dado de TextPoint .

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

Sintaxe

'Declaração
Function GreaterThan ( _
    Point As TextPoint _
) As Boolean

bool GreaterThan(
    TextPoint Point
)

bool GreaterThan(
    [InAttribute] TextPoint^ Point
)

abstract GreaterThan : 
        Point:TextPoint -> bool

function GreaterThan(
    Point : TextPoint
) : boolean

Parâmetros

Point
Tipo: EnvDTE.TextPoint
Obrigatório.TextPoint para comparar ao objeto do ponto de chamada.

Valor de retorno

Tipo: System.Boolean
true se Point tem um valor de propriedade menor de AbsoluteCharOffset comparado à propriedade de AbsoluteCharOffset do objeto chamando de EditPoint ; caso contrário, false.

Comentários

GreaterThan gera uma exceção de ArgumentException se Point não estiver no mesmo documento que o objeto do ponto de chamada.com VirtualPoint, GreaterThan compara as posições virtuais se o argumento é VirtualPoint.Caso contrário, compara as “físicos” posições.

Exemplos

Sub GreaterThanExample(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
