属性值

类型：System.Int32

示例

Sub DisplayColumnExample(ByVal dte As DTE2)

    ' Create a new text file.
    dte.ItemOperations.NewFile()

    ' Create an EditPoint at the start of the new document.
    Dim doc As TextDocument = _
        CType(dte.ActiveDocument.Object("TextDocument"), TextDocument)
    Dim point As EditPoint = doc.StartPoint.CreateEditPoint
    Dim i As Integer

    ' Insert 10 lines of text.
    For i = 1 To 10
        point.Insert("This is a test." & vbCrLf)
    Next

    ' Display EditPoint properties.
    MsgBox( _
        "AbsoluteCharOffset: " & point.AbsoluteCharOffset & vbCrLf & _
        "DisplayColumn: " & point.DisplayColumn & vbCrLf & _
        "AtEndOfDocument: " & point.AtEndOfDocument & vbCrLf & _
        "AtEndOfLine: " & point.AtEndOfLine & vbCrLf & _
        "AtStartOfDocument: " & point.AtStartOfDocument & vbCrLf & _
        "AtStartOfLine: " & point.AtStartOfLine)

    End Sub
