Using SMS and MMS Toolkit with Visual Basic 5.x/6.x (MM1 Connection)

The SMS and MMS Toolkit is a software development kit (SDK) to enhance an application or script with SMS, MMS and Pager functionality.
An 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.
An 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 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)

Pager features:

Send alpha-numeric Pager messages through SNPP

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 GSM:

   Dim objMm1Protocol As AXmsCtrl.MmsProtocolMm1
   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 GSM objects in the following way:

   Set objMm1Protocol = CreateObject("ActiveXperts.MmsProtocolMm1")
   Set objMmsConstants = CreateObject("ActiveXperts.MmsConstants")

The 'MmsMessage' and 'MmsSlide' objects aren't created as this point, as they will returned by the 'MmsProtocolMm1' object while retrieving the MMS messages.

Step 5: Receive MMS messages

The following code shows how to receive MMS messages:
