Answer 1

Finally i got the solution,what i did is



<mx:HTTPService id="savepcktdata"  method="POST"
                      url="{URL}com/...../..../PckInbox.aspx"
                      result="savepcktdata_resultHandler(event)"                        
                      resultFormat="text">
                  <mx:request>
                      <Operation>savepcktdata</Operation>       
                   <bytes>
                         {str64enc}
                   </bytes>
                  </mx:request>   
</mx:HTTPService>

You must pass the base64string as above through Httpservice from flex to dotnet

We will get the image as bytes after taking a pic from webcam and after getting bytes u need to
make some conversions to those image bytes as follows and then u need to pass to a base64 string below method describes how to do conversions;

[Bindable]public var imgbytes:ByteArray=new ByteArray(); 
[Bindable]public var str64enc:String="";

    protected function btnimage_clickHandler(event:MouseEvent):void
  {
    // TODO Auto-generated method stub
    if(webimage1.content==null)
    {
     takepicture1();
    }
    else if(webimage2.content==null)
    {
     takepicture2();
    }

 }

Here webimage1 is the id of image tag like...

 <mx:Image id="webimage1" height="18" width="20"/>



    public function takepicture1():void
   `{
     var urlRequest:URLRequest = new URLRequest();
     var picture1:BitmapData=new BitmapData(vddisplay.height,vddisplay.width);
     picture1.draw(vddisplay);
     webimage1.source=new Bitmap(picture1);
     var je1:JPEGEncoder=new JPEGEncoder(50);
     imgbytes=je1.encode(picture1);
     var base64enc:Base64Encoder=new Base64Encoder();
     base64enc.encodeBytes(imgbytes); 
     str64enc=base64enc.toString();
   }

`

In Dotnet;

string str = Convert.ToString(Request.Form["bytes"]);
