It is as simple as sending an email to whatever the email address is for that carrier, list here

http://www.livejournal.com/tools/textmessage.bml?mode=details

The application is simple but could easily be improved by validating each of the required fields through the use of regular expressions or by at least validating that the text associated with each of the text boxes is not an empty string.  To maintain the simplicity of the project, little in the way of error handling has been included.

The following figure (Figure 1) shows a properly configured collection of input fields in use:

Figure 1: The Demonstration Application in Use

A quick review of the code will reveal that there is little going on there.  The following imports were added to the top of the class:

Imports System

Imports System.Net.Mail

The System.Net.Mail import brings in the support necessary to transmit the messages generated using the application.  Following the imports and the class declaration, there is a declarations region identified and within that region is a collection of private member variables; these private member variables are created in order to supply each of the required elements of the message.

#Region "Declarations"

' message elements

Private mMailServer As String

Private mTo As String

Private mFrom As String

Private mMsg As String

Private mSubject As String

#End Region

At this point, the only thing left to do in code is to  write the following  three methods:
