Before we get started download “One Headlight” by the Wallflowers. Yea its a bit old but still rocks!

Now that have some music jamming in the background lets get started.

We need an ASP.NET web service if you don’t already have one create it; if you do then great. This example code is in C# it can easily be done in VB as well.

1. Let’s add an import to the top

using System.Web.Mail;

 
1a. Put “One Headlight” on repeat.

2. Now we need to create the web service function that sends the emails

[WebMethod]
public string sendEmail(string strMailTo, string strMailFrom, string strMailSubject, string strMailBody)
{
     //create the mail message
     MailMessage mail = new MailMessage();

     //set the addresses
     mail.From = new MailAddress(strMailFrom);
     mail.To.Add(strMailTo);

     //set the content
     mail.Subject = strMailSubject;
     mail.Body = strMailBody;
     mail.IsBodyHtml = true;

     //send the message
     SmtpClient smtp = new SmtpClient("127.0.0.1");
     smtp.Send(mail);

     //return message
     return "Message Sent!";
}

3. Test it by running the web service in debug mode.

Click on the sendMail link and you should see something like this

Screen Shot - Web Service - sendMail Function

fill it out and click Invoke. You need to make sure you have a SMTP server running on your machine. If you don’t you will get an error. I doubt you will be running it locally so you can upload it to your server and carry on to step 4.

4. Now that we have our web service function built we need to link it up in Adobe Flex. Make sure to replace “yourPassedValue” with some string value that you are passing from somewhere like a text field. If you want it to be static then remove the open and close Flex code tags “{}” and just type the string.

<mx:WebService id="yourWebServiceID" wsdl="http://www.domain.com/<b style="color:black;background-color:#ff66ff">Service</b>.asmx?WSDL" showBusyCursor="true">
       <mx:operation name="sendEmail">
           <mx:request>
                  <strMailTo>{yourPassedValue}</strMailTo>
                  <strMailFrom>{yourPassedValue}</strMailFrom>
                  <strMailSubject>{yourPassedValue}</strMailSubject>
                  <strMailBody>{yourPassedValue}</strMailBody>
           </mx:request>
      </mx:operation>
</mx:WebService>

5.  Now all that’s left is to add this to an action like a button click event

yourWebServiceID.sendEmail.send();

That’s it. I added an example below if it errors out its because the max relays have been reached. I will update it soon with a notification. I will also provide the source.
