以下是我用treeview控件按部門和員工顯示設備領用情況代碼.

‘設置第二級"員工"

nodindex.Sorted = True
recPlant.MoveNext
Next N
recPlant.Close
nodindex.Sorted = True
rec.MoveNext
Next I
rec.Close
End Sub

Private Sub Treeview_NodeClick(ByVal Node As Object)
Dim nodindex As Node
點擊事件為NodeClick
If Node.Key Like "部門*" Then
keyDepa = Mid(Node.Key, 3)
strDepa = Node.Text: Me.申報部門 = strDepa
End If
If Node.Key Like "員工*" Then
keyEm = Mid(Node.Key, 3)
strEm = Node.Text: Me.申報員工 = strEm
End If

If Node.Key Like "設備*" Then
keyPl = Mid(Node.Key, 3)
strPl = Node.Text: Me.設備名稱 = strPl: Me.設備編號 = keyPl
End If
End Sub
