主题：当前表统计的问题

请老师帮忙看看，下面的代码写的有问题，不能在click里应用，想实现根据对应的信息编号对SQLtable里面的条件行统计

Dim cr As DataRow = e.DataRow
Dim count As Integer
       count = cr.DataTables("流程_Table11").Compute("Count(信息编号)", "任务完成 = 0","信息编号 = '" & cr("信息编号") & "')
Dim lbl As WinForm.Label
lbl = e.Form.Controls("label107")
lbl.Text = "任务未完成人数: " & count

这样写，就对了

Dim cr As Row = Tables("流程_Table11").current
Dim count As Integer
    count = cr.Table.Compute("Count(信息编号)","信息编号 = '" & cr("信息编号") & "' And 任务完成 = 0")
Dim lbl As WinForm.Label
lbl = e.Form.Controls("label107")
lbl.Text = "任务未完成人数: " & count
