      1、用戶界面:

      </head>

      <body>
      <form method="post" action="del.asp" name="form1">
      <table>
      <tr>
      <td ><input type="checkbox" value="111" name="TradeName">電子郵件1</td>

      2、刪除文件del.asp
      <%
      '這行寫連接數(shù)據(jù)庫的代碼
      dim ID,strID
      strID=""
      For Each strID In Request.Form("TradeName")
      ID=Cint(strID)
      if strID<>"" then
      DelRs = Server.CreateObject("ADODB.Recordset")
      Conn.Execute "Delete From Tbname where ID="&Cstr(ID)
      strID=""
      end if
      Next

      Conn.Close
      Set Conn = Nothing
      Response.Redirect "成功刪除!"
