Load Data by HTTPService from Url into Flex text area as a string

Question

Hi all I want to use an HTTPService to load some data (number of columns and number of rows) which change randomly by a certain frequency I get the string like freq#ncols#nrows#value. How can i display for example: 1000#21#13#2391 that means: in 21 col, 13 row i have the value of 2391 which changes every 1 second. Thanks

Write a function that formats your raw string, something like:

public function formatColRowString(source:String):String{
    var data:Array = source.split('#');
    return 'in ' + data[1] + ', ' + data[2] + ' I have the value of ' + data[3] +' which changes every ' + data[0];
}

If you were to fill an ArrayCollection to populate a dataProvider, you would need a value object, something like:

package{

    public class RowColObject{

     private var _row:int;
     private var _col:int;
     private var _value:int;
     private var _updateTime:int;

     public function RowColObject(rawString:String = null){
      if(rawString && rawString.length > 0){
       var data:Array = rawString.split("#");
       _col = data[1];
       _row = data[2];
       _value = data[3];
       _updateTime = data[0];
      }
     }

     public function get row():int{
      return _row;
     }
     public function set row(value:int):void{
      _row = value;
     }
     public function get col():int{
      return _col;
     }
     public function set col(value:int):void{
      _col = value;
     }
     public function get value():int{
      return _value;
     }
     public function set value(value:int):void{
      _value = value;
     }
     public function get updateTime():int{
      return _updateTime;
     }
     public function set updateTime(value:int):void{
      _updateTime = value;
     }

    }

}

Not it's up to you to pick or make the proper component to display the data. That should do it.
