CitectVBA定制过程分析器：删除特定板下面特定的趋势笔

继续学习练习，如果想要删除板2（从1开始计数）下面的趋势笔2（从1开始计数），使用CitectVBA脚本如下：
Sub deletePanePen()
'删除板2下面趋势笔2
Dim pa As Object
Dim hPanes As Object
Dim hPane As Object
Dim hPens As Object
Dim hPen As Object
Dim panecount
Set pa=main_AN4
Set hPanes=pa.panes
panecount=hPanes.count
If panecount>=2 Then
Set hPane=hPanes.item(2)
Set hPens=hPane.pens
If hPens.count >1 Then
Set hPen=Hpens.item(2)
hPen.delete
End If
End If
End Sub
