These controls allow you to compose / parse messages in alternative MIME format with multiple file attachments, build and send Web Form POST requests and many other features.

The Web Update control will help you keep your customers and users informed about all the latest changes and software updates available from your web-server (Internet resource). It allows receiving updates from the Internet in the way similar to the Windows Update. The whole process of checking, downloading and updating can be fully customized by defining event sequences.

The SoapMessage allows you to combine the XML SOAP message and digitally sign (DSIG) it if necessary.

The SMTP, POP3, IMAP and HTTP Mail clients allow you to send and retrieve email messages over the Internet.

The Clever Internet ActiveX Suite controls provide the complete Client / Server solutions for the most common Internet protocols: SMTP, POP3, IMAP4, NNTP and FTP.

All server components represent the fully functional multithreaded servers with an ability to customize the user and thread performance settings, supports the most common protocols extensions.

Components can connect to the a server via the Secure Socket Layer (SSL / TLS) channel, and capable of encoding / decoding the message content, sending file attachments and many other useful features.

Also a set of additional classes and components are available: Mail Message, HTTP Request, GZip compressor, MIME Encoder, S/MIME message, SOAP message, HTML Parser. All these component make the application development process easy and clean. You can use these components separately from the main protocol components with any other library and even with your own socket implementation.
