Send E-mail from Flash using .Net (in 5 easy steps)

By | April 12, 2010

Sending emails from Flash using .Net is really simple all you need is a Flash Interface that sends the request to an ASPX page.  Here are the things you need

1. And ASPX Page that accepts the request (in this sample lets call is EmailSender.aspx)
2. A Flash frontend for users to post their messages (in this sample lets call is EmailForm.fla)
3. And Action Script class to process the message (in this sample lets call is EmailForm.as)


Step 1 : Create EmailForm.fla and add the following objects with the following properties

Name : Type = Input Text, Name = txtName
Email Address : Type = Input Text, Name =txtEmailAddress
Subject : Type = Input Text, Name =txtSubject
Message : Type = Input Text, Name =txtMessage
Error : Type = Dynamic Text, Name =txtError
Send Email Button : Type = Button, Name =btnSendEmail

Email Form Properties

Step 2 : Create an AS file, called EmailForm.as and save it in the same directory create and add these codes

New AS

package  
{
 import flash.display.MovieClip;
 import flash.display.SimpleButton;
 import flash.events.MouseEvent;
 import flash.utils.Timer;
 import flash.events.*;
 import flash.net.URLLoader;
 import flash.net.URLVariables;
 import flash.net.URLRequest;
 import flash.net.URLRequestMethod;
 import flash.net.URLLoaderDataFormat;
 import flash.ui.ContextMenu;
 import flash.ui.ContextMenuItem;
 import flash.net.navigateToURL;

 public class EmailForm extends MovieClip
 {
 private var oTimer:Timer;
 private var bCheckStatus:Boolean=false;

 public function EmailForm()
 {
 init();
 initListener();
 }

 private function init():void
 {

 }

 private function initListener():void
 {
 btnSendEmail.addEventListener(MouseEvent.MOUSE_DOWN,controlFields);
 }

 private function controlFields(m:MouseEvent):void
 {
 if(txtName.text!=''&&txtEmailAddress.text!=''&&txtSubject.text!=''&&txtMessage.text!='')
 {
 if(CheckEmail(txtEmailAddress.text))
 {
 bCheckStatus=true;
 sendEmail();
 }
 else
 {
 bCheckStatus=false;
 txtError.text='Email Address is Invalid';
 toggleAlert();
 }
 }
 else
 {
 bCheckStatus=false;
 txtError.text='You need to fill in required fields';
 toggleAlert();
 }
 }

 private function toggleAlert():void
 {
 oTimer=new Timer(2000,1);
 oTimer.addEventListener('timer',cancel);
 oTimer.start();
 }

 private function cancel(t:TimerEvent):void
 {
 txtError.text='';
 if(bCheckStatus)
 {
 txtName.text='';
 txtEmailAddress.text='';
 txtSubject.text='';
 txtMessage.text='';
 }
 bCheckStatus=false;
 }

 private function sendEmail():void
 {
 var oEmailFields:URLVariables=new URLVariables();
 oEmailFields.sEmail=txtEmailAddress.text;
 oEmailFields.sMessage=txtMessage.text;
 oEmailFields.sSubject=txtSubject.text;
 oEmailFields.sName=txtName.text;

 var oRequest:URLRequest=new URLRequest();

 oRequest.url='EmailSender.aspx';
 oRequest.method=URLRequestMethod.POST;
 oRequest.data=oEmailFields;
 var oLoader:URLLoader=new URLLoader();
 oLoader.dataFormat=URLLoaderDataFormat.VARIABLES;
 addListeners(oLoader);
 try
 {
 loader.load(oRequest);
 }
 catch (error:Error)
 {
 trace('Page Not Found');
 }
 }

 private function addListeners(d:IEventDispatcher):void
 {
 d.addEventListener(Event.OPEN,Initialize);
 d.addEventListener(ProgressEvent.PROGRESS,inProgress);
 d.addEventListener(Event.COMPLETE,Completed);

 d.addEventListener(HTTPStatusEvent.HTTP_STATUS,HTTPStatus);
 d.addEventListener(SecurityErrorEvent.SECURITY_ERROR,SecurityError);
 d.addEventListener(IOErrorEvent.IO_ERROR,IOError);
 }

 private function Initialize(e:Event):void
 {
 txtError.text='Sending ...';
 }

 private function inProgress(e:ProgressEvent):void
 {
 txtError.text='Sending ...';
 }

 private function Completed(e:Event):void
 {
 var loader:URLLoader=URLLoader(e.target);
 var vars:URLVariables=new URLVariables(loader.data);
 if(vars.answer=='ok')
 txtError.text='Message Sent';
 else
 txtError.text='Error (Message not Sent)!!!';
 toggleAlert();
 }

 private function SecurityError(e:SecurityErrorEvent):void
 {
 txtError.text='Error (Security)!!!';
 }

 private function HTTPStatus(e:HTTPStatusEvent):void {}

 private function IOError(e:IOErrorEvent):void
 {
 txtError.text='Error (IO)!!!';
 }
 public function CheckEmail(s:String):Boolean
 {
 var x:Number;
 var y:Number=0;
 var boolTest:Boolean=new Boolean();
 for(var i:Number=0;i<s.length;i++)
 {
 if(s.charAt(i)==' ')
 {
 boolTest=false;
 break;
 }
 if(s.charAt(i)=='@')
 {
 x=i;
 y++;
 }
 else if(i>x&&s.charAt(i)=='.'&&s.charAt(s.length-1)!='.')
 {
 y++
 boolTest=true
 break;
 }
 else
 {
 if(i==s.length-1)
 {
 boolTest=false;
 break;
 }
 }
 }
 return boolTest;
 }

 }
}

Step 3 : Use that class on your EmailForm.fla

Declare Class

Step 4: Create the EmailSender.aspx file and copy these codes

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class _Default : System.Web.UI.Page
{
 protected void Page_Load(object sender, EventArgs e)
 {
 if (Request.Form["sEmail"] != null)
 {
 string sPOSTEmail = Request.Form["sEmail"].ToString();
 string sPOSTMessage = Request.Form["sMessage"].ToString();
 string sPOSTSubject = Request.Form["sSubject"].ToString();
 string sPOSTName = Request.Form["sName"].ToString();

 MailMessage oMailMessage = new MailMessage();
 SmtpClient oSMTPClient = new SmtpClient();

 MailAddress oFromAddress = new MailAddress(sPOSTEmail, sPOSTName);

 string sEmailUser = "XXXXXXXXXXXXXX";
 string sEmailPassword = "XXXXXXXXXXXXXXXXX";
 string sEmailServer = "XXXXXXXXXXXXXXXXX";
 int iEmailServerSMTPPort = 25;

 oSMTPClient.Host = sEmailServer;
 oSMTPClient.Port = iEmailServerSMTPPort;

 System.Net.NetworkCredential oCredentials = new System.Net.NetworkCredential(sEmailUser, sEmailPassword);
 oSMTPClient.Credentials = oCredentials;

 oMailMessage.From = oFromAddress;
 oMailMessage.To.Add("XXXXXXXXXXXXXXXXXXXXXXX");
 oMailMessage.Subject = sPOSTSubject;

 oMailMessage.IsBodyHtml = true;
 oMailMessage.Body = sPOSTMessage;

 oSMTPClient.Send(oMailMessage);
 }

 }
}

Step 5: Youre ready to rock and roll, you can publish your site now
