例子

VBA：

Sub Example_DisplayLocked()
    ' This example scans the current drawing paper space Viewports
    ' and displays whether or not any of them are locked.
    
    Dim pviewportObj As Object
    Dim msg As String, DisplayState As String
    
    ' Make sure this drawing contains paper space viewports before continuing
    If ThisDrawing.PaperSpace.Count = 0 Then
        MsgBox "There are no paper space viewports in the current drawing."
        Exit Sub
    End If
    
    ' Go through each PViewport object in the drawing paper space
    ' and determine whether the paper space viewport is locked or not

    For Each pviewportObj In ThisDrawing.PaperSpace
        ' Determine if this is a paper space viewport
        If pviewportObj.ObjectName = "AcDbViewport" Then
            ' Determine if this paper space viewport is clipped
            DisplayState = IIf(pviewportObj.DisplayLocked, " is locked", " is not locked")
            msg = msg & "PViewport ID " & pviewportObj.ObjectID & DisplayState & vbCrLf
        End If
    Next

    ' Display locked state of paper space Viewports
    MsgBox msg
End Sub
