参数没有被指定问题！！郁闷
源代码：
protected   void   ImageButton1_Click(object   sender,   ImageClickEventArgs   e)
        {
                string   Temp   =   Request.Params[ "iCustomerId "];
                OleDbConnection   myconnection   =   new   OleDbConnection(AccessString   +   System   .Web   .HttpContext   .Current   .Server.MapPath(DataBase   ));
                OleDbCommand   mycommand;
                string   cmd3   =   "update   KHGL_CustomerPerson   set   cCusCode= "   +   cCusCode_Box.Text   +   ",cCusName= ' "   +   cCusName_Box.Text   +   " '   where   iCustomerId= "   +   Temp;  
                mycommand   =new   OleDbCommand   (cmd3,myconnection   );
                myconnection.Open();
                mycommand.ExecuteNonQuery();
                Response.Write( "更新成功 ");
                myconnection.Close();
        }
查看的局部变量：
cmd3= "update   KHGL_CustomerPerson   set   cCusCode= '1039200506090001 ',cCusName= '烟台华兴纸制品有限公司 '   where   iCustomerId=11 "

------解决方案--------------------
update 语句本身没有问题，
检查 字段名，表名 是否正确
------解决方案--------------------
string cmd3 = "update KHGL_CustomerPerson set cCusCode= ' " + cCusCode_Box.Text + " ',cCusName= ' " + cCusName_Box.Text + " ' where iCustomerId= " + Temp;
