以下是引用baoxyang在2009-4-9 18:49:00的发言: Dim dst2 As WinForm.DataList = e.Form.Controls("DataList2") if dst1.count>0 then Dim dr1 as DataRow = dst1.Current dim str as string = dr1("货品编码") cmd.CommandText = "execute CYMXB '" & str & "'" end if dst2.DataTable = cmd.ExecuteReader() dst2.Build() 请问上面的红色部分表示什么?
