标题：7.2和7.9发现的错误

   7.2和7.9更新我的系统出来一个错误,7.2之前一直正常.这个表里的代码有以下:

出来的错误如图:

 

此主题相关图片如下：7.2和7.9错误.jpg

贴出辅料明细表的CurrentChanged事件代码

上面就是全部的代码,没有什么特别的,我全部贴出了.

错误提示就是辅料明细的CurrentChanged事件

我知道呀,但是我用了一年多的代码,到最近两次错误提示,这是怎么回事?

因为7.2改写了筛选和排序代码

你贴的不是CurrentChanged的代码，因为该事件的e参数不会是e.DataRow

的确贴错了,应该是这一句:

 

  With Tables("辅料明细")
    If .Current Is Nothing Then
        Tables("集合输入_Table20").Filter= "False"
    Else
        Tables("集合输入_Table20").Filter = "商标 = '" & Tables("辅料明细").Current("商标") & "'"
    End If
End With

 

帮我看看!

Tables("集合输入_Table20").Filter= ""

With Tables("辅料明细")
    If .Position < 0  Then
        Tables("集合输入_Table20").Filter= "False"
    Else
        Tables("集合输入_Table20").Filter = "商标 = '" & Tables("辅料明细").Current("商标") & "'"
    End If
End With
