An easy way to working with Flash and Web Services.

Introduction

This sample will log you in with a Web Service, serialize the data from a database, and use the serialization class in Flash.

Background

You can get data from a server application in several ways, but I discovered that when working with .NET, using a serialization class is very easy.

Using the code

We will use the a Web Service and a serilazation class and a function in Flash to get the user information. Here is the login method in the Web Service:

[WebMethod]
public oUsers loginUser(string sUsername, string sPassword)
{
    oUsers objUsers = new oUsers();
    try
    {
        if( sUsername.Equals("admin") && 
            sPassword.Equals("admin") )
        {
            objUsers.sEmail = "admin@administrator.com";
            objUsers.sName = "Adam";
            objUsers.sPassword = "admin";
            objUsers.sUsername = "admin";
        }
        else
        {
            throw new ApplicationException("Wrong user!");
        }
    }
    catch
    {
        throw new ApplicationException("Error");
    }
    return objUsers;
}

Here is the serialization class:

[Serializable]
public class oUsers
{
    public string sName;
    public string sEmail;
    public string sUsername;
    public string sPassword;

    public oUsers()
    {
    }
}

Here is the Flash script for the root:

//stop the secvens of the time line
stop();

//importing the webservice classes
import mx.services.*;

//declareing the an global variable for easy access
_global.webServicen = 
  new WebService("http://localhost/WebServiceAndFlash/login.asmx?WSDL");

//cleaning up the textboxes

mcLogin.txtUsername.text = "admin";
mcLogin.txtPassword.text = "admin";
mcLogin.txtName.text = "";
mcLogin.txtEmail.text = "";
mcLogin.txtUser.text = "";
mcLogin.txtPass.text = "";

Given below is the script for the OnClick function:

on(release){
    var objServicen = _global.webServicen.loginUser(
        _root.mcLogin.txtUsername, _root.mcLogin.txtPassword);
    objServicen.onResult = function(result)
    {
        trace("login");
        //declare the Userobject

        var oUser = new objServicen.oUsers();
        oUser = result;
        
        _root.mcLogin.txtName = "SDF" + oUser.sName;
        _root.mcLogin.txtEmail = oUser.sEmail;
        _root.mcLogin.txtUser = oUser.sUsername;
        _root.mcLogin.txtPass = oUser.sPassword;
        
    }
    
    objServicen.onFault = function(fault)
    {
        _root.mcAlert._x = "-0.3";
        _root.mcAlert._y = "-0.7";
    }
}
