Método EditPoint.LessThan (TextPoint)
Retorna se o valor de AbsoluteCharOffset chamado de objeto de EditPoint for menor do que o do objeto dado de TextPoint .
Namespace: EnvDTE
Assembly: EnvDTE (em EnvDTE.dll)
Sintaxe
'Declaração
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
Parâmetros
- Point
Tipo: EnvDTE.TextPoint
Obrigatório.TextPoint para comparar ao objeto do ponto de chamada.
Valor de retorno
Tipo: System.Boolean
Um valor Booleano que indica se truePoint tem um valor de propriedade maior de AbsoluteCharOffset comparado à propriedade de AbsoluteCharOffset do ponto de chamada.
Comentários
LessThan gera ArgumentException se Point não estiver no mesmo documento que o objeto do ponto de chamada.com o objeto de VirtualPoint , LessThan compara as posições virtuais se o argumento é VirtualPoint.Caso contrário, compara as “físicos” posições.
Exemplos
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()

ByVal point2 As EditPoint)
If point1.LessThan(point2) Then

ElseIf point1.GreaterThan(point2) Then

ElseIf (point1.EqualTo(point2)) Then
MsgBox("point1 and point2 occupy the same location.")
End If
