Using The SMS and MMS Toolkit with ASP.NET (Visual Basic)

The SMS and MMS Toolkit is a software development kit (SDK) to enhance an application or script with SMS, MMS and Pager functionality. SMS messages can be sent using a GSM/GPRS modem, an SMPP provider, an HTTP compliant SMS provider or using a standard dialup or fixed-line SMS modem. MMS messages can be sent via a GSM/GPRS modem (MM1), an SMTP server (MM4) or an XML/SOAP compliant provider (MM7).

SMS features:

Send and receive numeric- and alphanumeric text SMS messages
Verify delivery of outgoing SMS messages
Support for multimedia SMS messages, including ringtones, pictures and logo's
Support for WAP Push, WAP Bookmarks, vCards, voicemail/e-mail/fax/MMS indications
Support for Unicode, to support foreign languages like Arabic, Chinese, Hebrew, etc.
Support for multi-part messages, to allow messages longer than 160 characters
Support for GSM modems, GSM phones, SMS/HTTP providers, SMPP (Short Message Peer to Peer) providers, TAP/XIO and UCP dial-in SMSC providers
Support Multi-threading environments. The component is thread-safe, which means it can be used in a multi-threaded environment
Samples included for various development platforms: MS Visual Basic, MS Visual Basic .NET, MS Visual C++, MS Visual Studio C# .NET, ASP, ASP .NET, Borland Delphi, Borland C++ Builder, Windows Powershell ColdFusion and more

MMS features:

Support for many multimedia formats incl.: JPG, GIF, PNG, BMP, WBMP, TIF, WAV, MP3, MIDI, AC3, GP3, AVI, MPG, MP4, VCARD, VCALENDAR, JAR and more
Support for MM1 (MMS over WAP), MM4 (MMS over SMTP) and MM7 (MMS over HTML/SOAP)

This document describes how the SMS and MMS Toolkit can be integrated into into ASP.NET projects.

Prerequisites

You must install and configre Internet Information Services (IIS) before using the SMS and MMS Toolkit with ASP .NET If you don't have IIS installed, use the following steps:

From the Control Panel, click 'Add/Remove Programs'. Select the 'Add/Remove Windows Components' icon from the left pane, then select 'Application Server' and click on 'Details'. You can now select both 'ASP .NET' and 'Internet Information Services (IIS)'. Click 'OK' to continue installation;
Make sure that ASP .NET is allowed on the web server:

Step 1: Download and install the SMS and MMS Toolkit

Download the the SMS and MMS Toolkit from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new ASP .NET VB Project

Launch Microsoft Visual Studio (for instance 'Microsoft Visual Studio 2005') from the Start menu. Choose 'New' from the 'File' menu and click on 'Web Site'. In the 'Web Site' dialog, select ASP .NET Web Site. Select a name for the application (for instance: 'DemoApp') and a name for the solution (for instance: 'DemoSolution'). Also, select the directory where you want to store the project (for instance: 'C:\MyProjects):

Step 3: Refer to the SMS and MMS Toolkit Library

Now that a new project has been created, you must add a reference to the SMS and MMS Toolkit in the project to be able to use the the SMS and MMS Toolkit objects. To do so, choose 'Add Reference...' from the 'Project' menu. In the 'Add Reference' dialog that pops up, select the 'COM' tab and select the ActiveXperts SMS and MMS Toolkit Type Library' as shown in the following picture:

(Click on the picture to enlarge)

Click 'OK' to close the 'Add Reference' dialog.

On top of your code, type the following line to use the SMS and MMS Toolkit namespace:

Imports AXmsCtrl

Step 4: Declare and create the SMPP object

In your Main function, declare and create the following objects:

Private objSmppProtocol As SmsProtocolSmpp
Private objSmsMessage As SmsMessage
Private objSmsConstants As SmsConstants

objSmppProtocol     = New SmsProtocolSmpp()
objSmsMessage       = New SmsMessage()
objSmsConstants     = New SmsConstants()

Step 5: Send and/or receive SMS messages

You can now send and/or receive SMS messages.

The following code shows how to send a SMS message:

webform.aspx.vb

Imports AXmsCtrl

Public Class WebForm1
    Inherits System.Web.UI.Page
    Protected WithEvents Text1 As System.Web.UI.HtmlControls.HtmlInputText

    Protected WithEvents TextRecipient As System.Web.UI.HtmlControls.HtmlInputText
    Protected WithEvents TextResult As System.Web.UI.HtmlControls.HtmlInputText

There are many working samples included with the product. You can also find them on the ActiveXperts FTP site: ftp.activexperts-labs.com/samples/mobile-messaging-component.

NOTE: Demo Projects are created with Microsoft Visual Studio 2005

The SMS and MMS Toolkit project ships with a set of Microsoft Visual Studio .NET samples, including samples for Microsoft ASP .NET (Visual Basic). The projects are created with Microsoft Visual Studio 2005.

Users with a later version of Microsoft Visual Studio can open such a project. The Visual Studio Conversion Wizard will guide you through the process of converting the project to the version used.
