主题：TreeView附带条件筛选

3、将目录树的AfterCheckNode事件代码设置为：

Dim nms As String() = {"产品","客户","雇员"} '指定生成目录树的各列
Dim qts As String() = {"'","'","'"} '指定将各列的值括起来的符号,这里都是字符型,所以都是单引号
Dim trv As WinForm.TreeView = e.Sender
Dim flt As String
Dim nd As WinForm.TreeNode
For Each nd In e.node.allNodes '清除子节点的选中标记
    nd.Checked = False
Next
nd = e.Node.ParentNode
Do While nd IsNot Nothing '清除父节点的选中标记
    nd.Checked = False
    nd = nd.ParentNode
Loop
For Each nd In trv.AllNodes
    If nd.Checked  Then
        Dim rts() As String = nd.FullPath.Split("\")
        Dim val As String = ""
        For i As Integer = 0 To rts.length - 1
            If val > "" Then
                val = val & " And "
            End If
            val = val & nms(i) & " = " & qts(i) & rts(i) & qts(i)
        Next
        If flt > "" Then
            flt = flt & " Or (" & val & ")"
        Else
            flt = val
        End If
    End If
Next
Tables("订单").Filter  = flt

现在想实现：窗口表中有一逻辑列名为“停用”，同时窗口中有一CheckBox控件（隐藏停用），用来控制是否显示停用的记录，当这个CheckBox勾选时（隐藏停用），点击TreeView节点复选框的时候，窗口表筛查出来的记录不包含停用的。反正，当CheckBox不勾选（即显示停用），窗口表筛查出来的记录包含停用的。不知道上面的通用代码如何修改？
