请问这是什么原因呢?

问题是我增加其它产品的时候没这个错,现发现有几个产品是这样的

ElseIf dr1("可编辑组范围").indexof( Tables("obas_part_spec").Current("org_no")) < 0 Then
                               
                                Messagebox.Show("你已经被限制只能编缉属于你组名数据!,如有疑问,请与管理员联系","提示",MessageBoxButtons.OK, MessageBoxIcon.Information)
                            Else
                                Tables("obas_part_spec").AddNew()
                                Tables("obas_part_spec").Current("part_no") = tbl.Current("part_no") '单行写入的代码 

 

 

将上面的代码"Tables("obas_part_spec").Current("part_no") = tbl.Current("part_no") '单行写入的代码 " 改为下面这样的,就没出错,我想就是这一行代码有问题,但我不明原因,因为其它产品是没问题的.

 

Tables("obas_part_spec").Current("part_no") = "O0000000000000023674" '单行写入的代码

且我检查过 tbl.Current("part_no") 是有数据的啊

将代码改成下面这样的,可以显示到 tbl.Current("part_no") 的值的,请问有谁能说一下原因吗?

 

ElseIf dr1("可编辑组范围").indexof( Tables("obas_part_spec").Current("org_no")) < 0 Then
                               
                                Messagebox.Show("你已经被限制只能编缉属于你组名数据!,如有疑问,请与管理员联系","提示",MessageBoxButtons.OK, MessageBoxIcon.Information)
                            Else
                                Dim s As String =tbl.Current("part_no")
                                  MessageBox.Show(s)

                                'Tables("obas_part_spec").AddNew()
                                'Tables("obas_part_spec").Current("part_no") = tbl.Current("part_no") '单行写入的代码

我将将码改一下,可以了,但还是想不明白原因啊!

改成这样的:

Tables("obas_part_spec").AddNew()

Dim s As String =tbl.Current("part_no")

Tables("obas_part_spec").Current("part_no") = s

 

有谁能解答一下吗? 这样有何分别?
