Using the SMS and MMS Toolkit with Visual C++ 5.x/6.x (MM4 Connection)

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).

This document describes how the SMS and MMS Toolkit can be integrated into Visual C++ projects.

Step 1: Download and install the SMS and MMS Toolkit

Download 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 C++ project

Launch 'Microsoft Visual C++' from the Start menu, and choose 'New' from the 'File Menu'. The 'New' dialog appears.

Select the type of project (for instance: 'Win32 Console Application'), enter a 'Project name' and select the 'Location':

Visual C

(Click on the picture to enlarge)

Select the kind of project, for instance a 'Hello, world!' application and click 'Finish':

Visual C

(Click on the picture to enlarge)

A new Project is created now.

Step 3: Refer to the SMS and MMS Toolkit Library

Before you can use the SMS and MMS Toolkit, you need to refer to the SMS and MMS Toolkit library. The actually reference files are shipped with the product and are located in the following directory:

 
C:\Program Files\ActiveXperts\xmstoolkit\Examples\Visual C++\Include

Copy all files in the above directory ('AXmsCtrl.h', 'AXmsCtrl_i.c' and 'AXmsConstants.h') to your project directory.

Step 4: Declare and create the SMS and MMS Toolkit objects

On top of your code, declare the following objects:

IMmsProtocolMm4  *m_pConnection = NULL;
IMmsMessage      *m_pMessage = NULL;
IMmsSlide        *m_pSlide = NULL;

Since the SMS and MMS Toolkit is a COM object, you must initialize the COM library before they can call COM library functions (e.g. SMS and MMS Toolkit functions):

CoInitialize(NULL);

Create the GSM objects in the following way:

CoCreateInstance ( CLSID_MmsProtocolMm4, NULL, CLSCTX_INPROC_SERVER, IID_IMmsProtocolMm4, (void**) &m_pConnection );
CoCreateInstance ( CLSID_MmsMessage,     NULL, CLSCTX_INPROC_SERVER, IID_IMmsMessage,     (void**) &m_pMessage );
CoCreateInstance ( CLSID_MmsSlide,       NULL, CLSCTX_INPROC_SERVER, IID_IMmsSlide,       (void**) &m_pSlide );

Step 5: Send MMS messages

You can now send MMS messages using a MM4 (SMTP) MMSC provider.

The following code shows how to send a MMS using C++ :
