Support for Unicode, to support foreign languages like Chinese, Turkisch, 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, 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 Visual Basic projects.

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 Visual Basic project

Launch 'Microsoft Visual Basic' from the Start menu, and choose 'New' from the 'File Menu'. The 'New Project' dialog appears.
Select 'Standard Exe' and click 'OK':

Step 3: Refer to the SMS and MMS Toolkit Library and create the objects

A new Project is created, with a blank form.

First, you must add a reference to the SMS and MMS Toolkit in the project to be able to use the MMS objects. To do so, choose 'References...' from the 'Project' menu. In the 'References' dialog that pops up, enable the 'ActiveXperts SMS and MMS Toolkit Type Library' reference as shown in the following picture:

(Click on the picture to enlarge)

Click 'OK' to close the 'References...' dialog.

Then, select the Project form and choose 'View Code' from the context menu:

(Click on the picture to enlarge)

On top of your code, declare the following objects for MM4:

   Dim objMm4Protocol  As AXmsCtrl.MmsProtocolMm4
   Dim objMmsConstants As AXmsCtrl.MmsConstants
   Dim objMmsSlide     As AXmsCtrl.MmsSlide
   Dim objMmsMessage   As AXmsCtrl.MmsMessage

Step 4: Create the objects

From the Code window, select 'Form'. The Private Sub 'Form_Load()' will be displayed now.
In the 'Form Load' function, create the MMS objects in the following way:

   Set objMm4Protocol  = CreateObject("ActiveXperts.MmsProtocolMm4")
   Set objMmsConstants = CreateObject("ActiveXperts.MmsConstants")
   Set objMmsMessage   = CreateObject("ActiveXperts.MmsMessage")
   Set objMmsSlide     = CreateObject("ActiveXperts.MmsSlide")

Step 5: Send MMS messages

The following code shows how to send MMS messages:
