Flash remoting in AS 3.0 to ASP.NET 2.0 flash.net

[danmo]

Hi, I am new to the forum, so sorry if I'm posting this in the wrong section.

I am having trouble understanding how to use flash remoting in CS3, using Actionscript 3.0 and trying to remote to an aspx page in ASP.NET 2.0 (using c#)

How do I go about doing this?

Has anyone done this before?

All I can find are AS 2.0 examples that are mainly for php.

I am trying to use the flash.net classes that are in CS3, but so far am having no luck :(

Any help and advice would be much appriciated.

Thanks, Daniel.

I think it has found my gateway.aspx - but I get this error "NetConnection.Call.BadVersion" Anyone know what It means, or is reffering to?

Thanks, Dan.

Hi,
I need to see your Actionscript code.

[danmo]

Hi, thanks for the reply.
I have 2 classes

1.

package
{
    import flash.net.NetConnection;
    import flash.net.ObjectEncoding;
    
    public class RemotingService extends NetConnection
    {
        function RemotingService(url:String)
         {
              // Is this the right coding?
              objectEncoding = ObjectEncoding.AMF0;

              // Connect to gateway
            connect(url);

         }
     }
}

2.

package
{
    import flash.net.*;
    import flash.display.*;
    import flash.events.*;
    import flash.text.*;
    
    public class RemotingTest extends Sprite
    {
        //private var rs:RemotingService;
        private var nt:NetConnection;
        private var t:TextField = new TextField();
        
        function RemotingTest()
        {
            //just a button on the stage - so i can click it to start the code running
            btnRemote.addEventListener(MouseEvent.CLICK, btnRemote_Click);            
        }

                //should this be The browser is not supported.... ? cos is embeded in aspx page so should be able to just use gateway.aspx? flash
                //gives me error if invalid parameter if don't have http:// at front

            }
        }

And the code behind, just to see if will go into it

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    public void Test()
    {
//i have a break point here
        string strTemp = "";
    }
}

If the remoting did work, would it hit my break point?
Am not sure what I need to do in order to get this to work.

Hope someone can help me with this.

Thanks a lot, Dan.

where it says the browser if not supported - it was because I had tried to put http : //localhost

Thanks, Dan.

[danmo]

Any ideas? I'm sure I must have got somewhere close to the solution.

I'm also using vista, if that makes any difference for some reason.

Thanks, Dan.

Hi, couldn't see how to edit my post, but I am not using the 1st class anymore, was using it earier on, but just the 2nd one in the post.

Thanks, Dan.

[danmo]

ok, by changing the permission, I can now get it to go to any page in my asp site, however it only goes to the page load of that page, and I cannot get it to go to the function I am trying to acess.

Any ideas? Surely someone on here would know how to do this?

Thanks, Dan.

I've been trying to figure this out as well. Anybody have any ideas?

[danmo]

Hi, the solution to this is to put all the aspx pages in the same namespace, this also needs to be updated on the aspx page in the inherits"namespace.class" at the top.

The use the connection of the gateway, using full address.

Then, when do call, call to namspace.pageclass
this will take you to the pageload of that page then you do:
//i called it flash on the aspx page
if (flash.Params.count > 0)
{
Test(flash);
}

you need a function test (or whatever to take in a flashgateway.flash - or whatever it's called)

function Test(flashgateway.Flash flash)
{
do stuff with flash like the params in an array
Also to send something back to the flash:

flash.Result = "whatever you want to send back";
}

Hope this helps someone!!

Cheers, Dan.
