EditPoint.GreaterThan メソッド (TextPoint)

[アーティクル]
08/09/2011

EditPoint オブジェクトの AbsoluteCharOffset プロパティの値が、指定した TextPoint オブジェクトのその値より大きいかどうかを返します。

名前空間: EnvDTE
アセンブリ: EnvDTE (EnvDTE.dll 内)

構文

'宣言
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

パラメーター

Point
型: EnvDTE.TextPoint
必ず指定します。呼び出しポイントのオブジェクトと比較する TextPoint。

戻り値

型: System.Boolean
Point の AbsoluteCharOffset プロパティ値が呼び出し元の EditPoint オブジェクトの AbsoluteCharOffset プロパティと比較して小さい場合は true を返します。それ以外の場合は false を返します。

実装

TextPoint.GreaterThan(TextPoint)

解説

Point が呼び出しポイントのオブジェクトと同じドキュメント内にない場合、GreaterThan は ArgumentException 例外をスローします。 VirtualPoint では、GreaterThan は、引数が VirtualPoint の場合には仮想位置を比較します。それ以外の場合は、"物理" 位置を比較します。

例

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
    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()
    CompareEditPoints(point1, point2)

End Sub

Sub CompareEditPoints(ByVal point1 As EditPoint, _
    ByVal point2 As EditPoint)

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