这里写错了……

 嗯嗯，明白了。把代码复制过去就行了。

Dim zc As WinForm.TextBox = e.Form.Controls("TextBox1")
Dim zh As WinForm.TextBox = e.Form.Controls("TextBox2")
With Tables("订单总表")
    zc.text =   .Rows( .TopPosition)("订单号")
    zh.Text  =   .Rows( .BottomPosition)("订单号") 
End With

Dim filter As String = "订单号 >= '" & zc.Text & "' And 订单号 <= '" & zh.Text & "'"
Dim dt As DataTable = DataTables("临时表")
dt.DataRows.Clear
For Each bfh As String In DataTables("订单明细").GetUniqueValues(filter, "背番号")
    Dim ndt As DataRow = dt.AddNew
    ndt("背番号") = bfh
    ndt("出货总数量") = DataTables("订单明细").Compute("Sum(数量)", filter & " And 背番号 = '" & bfh & "'")
Next
