以下是我用treeview控件按部门和员工显示设备领用情况代码.

Private Sub Treeview_NodeClick(ByVal Node As Object)
    Dim nodindex As Node
   点击事件为NodeClick
    If Node.Key Like "部门*" Then
        keyDepa = Mid(Node.Key, 3)
        strDepa = Node.Text: Me.申报部门 = strDepa
    End If

        keyEm = Mid(Node.Key, 3)
        strEm = Node.Text: Me.申报员工 = strEm
    End If

    If Node.Key Like "设备*" Then
        keyPl = Mid(Node.Key, 3)
        strPl = Node.Text: Me.设备名称 = strPl: Me.设备编号 = keyPl
    End If
End Sub
