例：VBA获取shape position

Public Sub LocationTable()
     ‘This routine will create a text file of the location and size of all 2-d shapes
     ‘ on the current page
    Dim shpObj     As Visio.Shape, celObj As Visio.Cell
    Dim ShpNo      As Integer, Tabchr     As String, localCent As Double
    Dim LocationX  As String, LocationY   As String
    Dim ShapeWidth As String, ShapeHeight As String

     ‘Open or create text file to write data
    Open "D:\LocationTable.txt" For Output Shared As #1

    Tabchr = Chr(9) ‘Tab

     ‘Loop Shapes collection
    For ShpNo = 1 To Visio.ActivePage.Shapes.Count

        Set shpObj = Visio.ActivePage.Shapes(ShpNo)
        shapeCount = shpObj.Shapes.Count
        If shapeCount > 1 Then
          i = 1
          For i = 1 To shapeCount
              MsgBox vsoShape.Shapes(i).Text
          Next i
        Else
        If Not shpObj.OneD Then ‘ Only list the 2-D shapes
                ‘Get location Shape
               Set celObj = shpObj.Cells("pinx")
               ‘localCent = celObj.Result("mm")
               localCent = celObj.Result("inches")

               LocationX = Format(localCent, "000.0000")
               Set celObj = shpObj.Cells("piny")
               localCent = celObj.Result("inches")
               LocationY = Format(localCent, "000.0000")

                ‘Get Size Shape
               Set celObj = shpObj.Cells("width")
               localCent = celObj.Result("inches")
               ShapeWidth = Format(localCent, "000.0000")
               Set celObj = shpObj.Cells("height")
               localCent = celObj.Result("inches")
               ShapeHeight = Format(localCent, "000.0000")

               ‘Write values to Text file starting Name of Shape
               Print #1, shpObj.Name; shpObj.Text; Tabchr; _
               Tabchr; LocationX; Tabchr; LocationY; _
               Tabchr; ShapeWidth; Tabchr; ShapeHeight
        End If

    Next ShpNo
     ‘Close Textfile
    Close #1

     ‘Clean Up
    Set celObj = Nothing
    Set shpObj = Nothing
End Sub

经过修改，提取指定shape。
