Flex+AS3中文件读入与写出及Datagrid自动获取行号和socket发送数

Flex+AS3中文件的读入并写入Datagrid中：

??protected function button4_clickHandler(event:MouseEvent):void
???{??
????
????// test.text += "n";
????// test.text += "DIP11:"+DIP11+"n";
????var urlRequest:URLRequest = new URLRequest("D:Hello.txt");
????var urlLoader:URLLoader=new URLLoader(urlRequest);
????function readData():void
????{
?????
?????var data:String = urlLoader.data;
????
?????var body:Array = data.split("n");
?????
?????for(var i:int = 1; i< body.length; i++ )
?????{
??????var info:Array = body[i].toString().split("??? ");
??????
??????var B1:String=info[0];??????????????????
??????var B2:String=info[1];
??????var B3:String=info[2];
??????var B4:String=info[3];
??????var B5:String=info[4];
??????var B6:String=info[5];
??????var B7:String=info[6];
??????var B8:String=info[7];
??????var B9:String=info[8];
??????var B10:String=info[9];
??????var B11:String=info[10];
??????var B12:String=info[11];
??????
??????
??????//Alert.show("2");
??????array.addItem({A:B1,B:B2,C:B3,D:B4,E:B5,F:B6,G:B7,H:B8,I:B9,J:B10,K:B11,L:B12});
??????DataGrid1.dataProvider=array;
??????
???????
?????}
?????
?????gettextdata(array);
?????//var column:int=DataGrid1.columnCount;
?????//var row:int=model.textdata.length;?
????}
????
????
????urlLoader.addEventListener(Event.COMPLETE,readData);
????
???}?

Flex+AS3中把Datagrid中数据写入TXT文件：

protected function button6_clickHandler(event:MouseEvent):void
???{
????
????var exportFile:FileReference = new? FileReference();
????exportFile.addEventListener(Event.COMPLETE,saveComplete);
????var mbytes:String="source_port_id ";
??????? mbytes=mbytes+"rn";
????for(var i:int=0; i<model.textdata.length;i++) {
?????
?????mbytes=mbytes+model.textdata[i]+"rn";
?????
????}
????
????exportFile.save(mbytes,"Write.txt");
????
???}

Flex+AS3中Datagrid第一列自动显示行号：

<mx:DataGridColumn? dataField="HEAD"? headerText="TrafficDemandID"? editable="true">
???<mx:itemRenderer>
????<mx:Component>
?????<mx:Label text="{outerDocument.genrowno(data)}" />
????</mx:Component>
???</mx:itemRenderer>
???</mx:DataGridColumn>

outerDocument.genrowno(data)函数如下：（必须是public类型的）

public function genrowno(hh:Object):String {
????var colomcount:String=DataGrid1.dataProvider.getItemIndex(hh)+1;
????return colomcount;
???}

Flex+AS3中socket发送数据：

msocket=new Socket();

?msocket.connect(DIP11,9998);

var len:int = 12+(model.textdata.length)*48; ?????writeHeader(CREQ,len); ?????socket.writeInt(1); ????? ?????var myarray:Array=new Array(); ?????for(var j:int=0;j<model.textdata.length;j++) ?????{?? ??????Alert.show(model.textdata[j],"message"); ??????myarray= model.textdata[j].split("|"); ??????for(var i:int=0;i<myarray.length;i++) ??????{ ???????socket.writeInt(int(myarray[i].valueOf())); ??????? ??????} ?????} ?????socket.flush();
