主题：品牌如何按“助记码”产生的数字规律自动递增编号？

我这边运行不了,请测试一下.

你这个概念有问题吧,因为是输入了品牌,才会知道里面有几条记录,还要复制干吗?

   另外只要品牌列输入数据立马会跟你挑明有几条数据的

修改了一下:

If e.DataCol.Name  = "品牌" Then
    Dim dr As DataRow
    Dim Filter As String
    dr = DataTables("表A").Find("品牌 = '" &e.newValue & "'")
    If dr IsNot Nothing Then '如果找到的话
        Tables("表A").Filter = "品牌 = '" & e.NewValue & "'"
        Dim r As Integer = CurrentTable.Rows.Count-1
              If r > 0 Then
            Return          
        End If
    End If
End If

If e.DataCol.Name  = "品牌" Then
    If e.NewValue > ""  Then
        Dim s1 As String = GetPy(e.NewValue,True)
        Dim s2 As String
        Dim cs() As String = New String() {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"}
        Dim ns() As String = new String(){15,52,54,13,33,12,11,21,43,22,23,24,25,51,44,45,35,32,14,31,42,53,34,55,41,26}
        For i As Integer = 0 To s1.length -1
            Dim s3 As String = s1.Chars(i)
            If Char.IsNumber(s3)  = False Then
                For n As Integer =0 To cs.Length -1
                    If cs(n) = s3 Then
                        s3 = ns(n)
                        Exit For
                    End If
                Next
            End If
            s2 = s2 & s3
        Next
        s2 = s2.PadRight(4,"0")
        s2 = s2.SubString(0,4)
        Dim drs As List(of DataRow) = e.DataTable.Select("编号 Like '" & s2 & "*' And [_Identify] < " & e.DataRow("_Identify"))
        If drs.Count = 0
            e.DataRow("编号") = s2 & "01"
        Else
            e.DataRow("编号") = s2 & Format(drs.count + 1,"00")
        End If
    Else
        e.DataRow("编号") = Nothing
    End If
End If

去除了提示框,转为默认：品牌已有过记录的，编号为空；新品牌编号自动新增。

另有一个问题请教：如果“编号列”编号只能由品牌自动产生，不能直接编缉，但编号可以复制到其它地方，请问如何设置？

类似锁定非空内容，参考：

 

还来一个例子，我们知道易表有一个锁定非空内容的功能，也就是只有空白单元格才能输入数据，一旦输入就不能修改，在Foxtable我们也可以很轻松地实现这个功能，例如希望锁定“标注”列的非空内容：

If e.Col.Name = "标注" AndAlso e.Row.IsNull("标注") = False Then
    e.Cancel = True
End If

 

 

懂得变通了,OK.非常好了.

品牌自动编号测试时遇到一个问题：“克隆行”时品牌编号自动递增，要阻止，请问如何设置？（等于同一品牌出现多个编号）

编号不就是要递增吗？

 

货品资料录入思路：品牌-产生品牌编号-产生货品编号----  同一品牌只使用同一个品牌编号，上传一个项目帮我查一下。

不要递增，那就去掉代码中递增的代码，改为：

 

If e.DataCol.Name  = "pp" Then
    If e.NewValue > ""  Then
        Dim s1 As String = GetPy(e.NewValue,True)
        Dim s2 As String
        Dim cs() As String = New String() {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"}
        Dim ns() As String = new String(){15,52,54,13,33,12,11,21,43,22,23,24,25,51,44,45,35,32,14,31,42,53,34,55,41,26}
        For i As Integer = 0 To s1.length -1
            Dim s3 As String = s1.Chars(i)
            If Char.IsNumber(s3)  = False Then
                For n As Integer =0 To cs.Length -1
                    If cs(n) = s3 Then
                        s3 = ns(n)
                        Exit For
                    End If
                Next
            End If
            s2 = s2 & s3
        Next
        s2 = s2.PadRight(4,"0")
        s2 = s2.SubString(0,4)
        e.DataRow("ppbh") = s2
    Else
        e.DataRow("ppbh") = Nothing
    End If
End If
