关于筛选树的问题,下面的代码都是仿帮助的，但执行的时候会有错误提示，帮忙看下是什么问题，谢谢

AfterLoad

Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.CommandText = "SELECT DISTINCT Year(月份营运报表_日期) As 年, Month(月份营运报表_日期) As 月, 服务执行单据记录表_客户站点 From {综管}"
dt = cmd.ExecuteReader()
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(dt, "年|月|服务执行单据记录表_客户站点")

    Case 0
        Dim y As Integer = value(0)
        d1 = New Date(y,1,1) \'取得该年的第一天
        d2 = new Date(y,12,31) \'取得该年的最后一天
        Filter = "月份营运报表_日期 >= #" & d1 & "# And 月份营运报表_日期 <= #" & d2 & "#"
