ActiveEmail SMTP/POP3 Toolkit is a software development kit (SDK) that enables the user to send (SMTP) and receive (POP3) e-mail messages. ActiveEmail supports SMTP, POP3, multiple recipients (To, CC, BCC), multiple attachments (ASCII and binary), rich text body formats (RTF/HTML), Unicode, multiple character sets, SMTP authorization (AUTH PLAIN, AUTH LOGIN, AUTH CRAM MD5), POP3 authorization (Plain, APOP), POP3 header download, different character sets (including arabic, chinese, japanese, russian, greek, hebrew and many more), different encodings (including 7/8 bit, quoted-printable, base64).
Introduction
In this example we are going to use Visual Studio 2008 to create a C++ application project named 'DemoApp'. We are going tot store this project in the directory 'C:\MyProjects'. All of these names can be changed according to your preferences. This demo project will ask the user to enter the username and password of the POP3 server where we will download the messages.
Step 1: Download and install the ActiveEmail Toolkit
Download the ActiveEmail 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: 'Win32 Console Application', enter a 'Project name' and select the 'Location':
(Click on the picture to enlarge)
Select the kind of project, for instance a 'Hello, world!' application and click 'Finish':
(Click on the picture to enlarge)
A new Project is created now.
Step 3: Refer to the ActiveEmail Toolkit Library
Before you can use the ActiveEmail Toolkit, you need to refer to the ActiveEmail Toolkit library. The actually reference files ship with the product and are located in the following directory:
C:\Program Files\ActiveXperts\ActiveEmail Toolkit\Samples\Visual C++\Include
ActiveXperts recommends to make use of the MmWrapper.h and MmWrapper.cpp COM wrappers. To do so, include 'MmWrapper.h' in your source file, and add 'MmWrapper.cpp' to your project so it will be compiled and linked together with your program code.
Step 4: Declare and create the ActiveEmail Toolkit objects
On top of your code, declare the following objects (defined in 'MmWrapper.h'):
CPop3 objPop3; CEMailMessage *pObjMessage = NULL;
Step 5: Receive e-mail messages
The following code will download and display all messages from the POP3 server:
for( i = 1; i < lNumMessages + 1 ; i++ )
{
objPop3.GetEmailHeader ( i, &pObjMessage );
_tprintf( _T( "Mail From : %s\n" ), pObjMessage->getFromAddress( strValue ).t_str() );
_tprintf( _T( "Mail To : %s\n" ), pObjMessage->getToAddress( strValue ).t_str() );
_tprintf( _T( "Mail Subject : %s\n" ), pObjMessage->getSubject( strValue ).t_str() );
_tprintf( _T( "Mail Size : %ld\n"), pObjMessage->getSize() );
_tprintf( _T( "Mail Sent : %s\n" ), pObjMessage->getDate( strValue ).t_str() );
_tprintf( _T("\n") );
}
