       var number:Number; 
       var code:String; 
       var checkCode:String =""; 
       //get 4 radom 
      for(var i:int=0; i<4; i++) 
      { 
          ran=Math.random(); 
          number =Math.round(ran*10000);            //get result like 0.1234 
          if(number % 2 == 0) 
            code = String.fromCharCode(48+(number % 10));        //0's ASCII code is 48 
          else 
            code = String.fromCharCode(65+(number % 26)) ;        // A's ASCII code is 65 
          checkCode += code; 
      } 
      return checkCode; 
  }
