大红袍老师：请您帮我审查一下签到表打印加载的问题，基本思路是得到FILTER后，对这个进行OR 和 AND 划分，得到的数组分别给到短日期，起始时间，教室三个变量中，再进行筛选，但总是报错，不知哪出问题？

请指导

DataTables("考试数据表").LoadFilter = ""
DataTables("考试数据表").Load

Dim nms As String() = {"短日期","起始时间","教室"} '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.Form.Controls("签到单时间")
Dim filter As String
For Each nd As object In trv.AllNodes
    If nd.Level > 2 Then
        If nd.Checked  Then
            Dim rts() As String = nd.FullPath.Split("\")
            Dim val As String = ""
            For i As Integer = 1 To rts.length - 1
                If val > "" Then
                    val = val & " And "
                End If
                val = val & nms(i-1) & " = " & qts(i-1) & rts(i) & qts(i-1)
            Next
            If filter > "" Then
                filter = filter & " Or (" & val & ")"
            Else
                filter = val
            End If
        End If
    End If
Next

filter = filter.Replace("(","").Replace(")","")

msgbox(filter)
