Dim tbn As String = Args(0)
Dim key As String = Args(1)
Dim Result As DialogResult
Result = MessageBox.Show("确定要删除[ " & Tables(tbn).Current(key) & " ]的所有资料吗?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question)
If Result = DialogResult.Yes Then
    MessageBox.Show("[ " & Tables(tbn).Current(key) & " ]的所有资料已经删除成功!","提示")
    Tables(tbn).Current.Delete
Else
e.Cancel =True
End If
Return Nothing

不太明白，能不能就上面这段给我写下代码呢?

调用的时候代码怎么判断呢？用这样的方式？

Dim s As Boolean = Functions.Execute("ceshi","供应商资料主表","简称")

if s = true

....

else

...

end if

这样？

比如改造SQL数据库的自动编号

Dim djsj As String = Args(0)
Dim bh As String  =Args(1)
Dim qz As String =Args(2)
Dim dr As DataRow = Args(3)
Dim pf As String
If dr.RowState <> DataRowState.Added Then \'如果不是新增行
    Return Nothing \'那么返回
ElseIf dr.IsNull(djsj) Then \'如果没有输入日期
    \'e.Cancel = True \'取消保存此行
    MessageBox.Show("必须输入日期!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
    Return Nothing
Else
    pf = Format(dr(djsj),"yyMMdd") \'否则获得编号的前缀,两位年,两位月
End If
Dim cmd1 As New SQLCommand
Dim cmd2 As New SQLCommand
Dim Key As Integer
Dim nm As String = Args(4)
cmd1.C \'设置数据源名称
cmd2.C
cmd1.commandText = "Select Count(*) From [编码规则] Where [前缀] = \'" & pf & "\' And 表名 = \'" & nm & "\'"
If cmd1.ExecuteScalar = 0 Then \'如果编号表不存在前缀的行,那么增加一行
    cmd1.commandtext = "Insert Into 编码规则 (表名, 前缀, 序号) Values(\'" & nm & "\',\'" & pf & "\',1)"
    cmd1.ExecuteNonQuery
End If
cmd1.commandText = "Select [序号] From [编码规则] Where [前缀] = \'" & pf & "\' And 表名 = \'" & nm & "\'"
Do
    Key = cmd1.ExecuteScalar() \'从后台获得顺序号
    cmd2.commandText = "Update [编码规则] Set [序号] = " & (Key + 1) & " Where [序号] = " & Key & " And [前缀] = \'" & pf & "\' And 表名 = \'" & nm & "\'"
    If cmd2.ExecuteNonQuery() > 0 Then \'更新顺序号
        Exit Do \'更新成功则退出循环
    End If
Loop
dr(bh) =  qz & pf & Format(Key,"00")

我卡在这里卡了一天了

用bin的方法就可以了或者你把e当参数传递进去就可以使用了
