--  [求助]筛选树的反选方法
能够加个按钮，实现反选的效果吗，或者双击节点，实现反选。
此主题相关图片如下：反选.png

Dim nms As String() = {"状态","部门"} \'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)
msgbox(nms(i))
Next
If flt > "" Then
flt = flt & " Or (" & val & ")"
Else
flt = val
End If
End If
Next
Tables("人员信息表").Filter = flt

Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
For Each nd As WinForm.TreeNode In trv.AllNodes
    nd.Checked = not nd.Checked
Next

反选实现了。但是没有应用到筛选上去。。而treeview里面的代码又不能放到 button里面去，应该如何处理呢

多谢了。另外请问下，能不能让双击节点的时候不会展开目录树呢。
