功能：第2列输入品牌（汉字、数字、英文），第1列自动生成4位数字+2位顺序号。
编号规则：1 品牌为汉字的，取第一二个汉字拼音助记码转换为数字，如
            “其它”助记码为“QT”，字母对应的数字为35 31
             （A=15 B=52 C=54 D=13 E=33 F=12 G=11 H=21 I=43 J=22
K=23 L=24 M=25 N=51 O=44 P=45 Q=35 R=32 S=14 T=31
U=42 V=53 W=34 X=55 Y=41 Z=26 此为五笔字根所在键位）
自动生成编号：35 31 01（01为顺序号，自动递增）
          2 品牌为英文的，取第一二个字母转换即可
          3 品牌为数字的，取第一二三四数字即可，不足后面补0（如“3M” 3 25 0 ）

按数字规律自动递增顺序号：

  “天骄”312201

  “天杰”312202

  “添美”312501（不是312503）

  “特美”312502

  “3M”325001（3 25 0 01）

要清除编号，可以改一下代码：
 
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

如果不单独建立“品牌资料表”，而是在增加货品资料时，“品牌”直接在货品资料中录入，能否这样设置：当“品牌”有重复值时，跳转到该品牌最末条记录所在行，并提示“该品牌已有N条记录，是否复制当前行，是、否”；否则提示“该品牌资料未记录”并自动新增品牌编号。请帮忙写下代码。谢谢！
