The SocketTools Visual Edition consists of 16-bit Visual Basic (VBX) controls and both 16-bit and 32-bit ActiveX (OCX) controls for use with visual development environments such as Visual Basic, Visual C++ and Delphi. A total of twenty controls provide client interfaces for the major application protocols such as the File Transfer Protocol, Hypertext Transfer Protocol, Simple Mail Transfer Protocol, Domain Name Service and Telnet. All versions of Visual Basic from 2.0 and later are supported, and the ActiveX controls can be used with any 32-bit development tool that supports COM and the ActiveX control specification.

All of the controls share many common attributes. The network controls support both synchronous (blocking) and asynchronous modes of operation, and also include the ability to log the Windows Sockets function calls for debugging purposes. All of the controls are thread-safe and can be used in multithreaded containers, such as Internet Explorer. With the exception of the visually oriented controls (the browser, image viewer and terminal emulation controls), they can also be used as simple Automation objects, without requiring that they be placed on a form or inside another container.

With full support for both 16-bit and 32-bit Windows platforms, illustrative samples, comprehensive online help and a tutorial to help developers get started, the SocketTools Visual Edition provides the greatest functionality and broadest range of features available for building Internet and intranet applications. The controls are completely royalty free and include a 30-day money-back guarantee.

The SocketTools Library Edition consists of 16-bit and 32-bit dynamic link libraries (DLLs), suitable for use with virtually any Windows development environment or scripting tool. A total of nineteen libraries provide client interfaces for application protocols such as the File Transfer Protocol, Hypertext Transfer Protocol, Simple Mail Transfer Protocol and Telnet protocol. A library version of our popular SocketWrench component is also included, which provides a high-level interface for general purpose sockets programming. The application program interface for the Library Edition is implemented with a simple elegance that makes it easy to use with any language, not just C or C++.

All of the libraries share many common attributes. The network libraries support both synchronous (blocking) and asynchronous modes of operation. All of the libraries are thread-safe and can be used in multithreaded applications. With full support for both 16-bit and 32-bit Windows platforms, illustrative samples and comprehensive online help, the Library Edition offers the functionality, features and performance needed to build professional applications for the Internet and intranet. The controls are completely royalty free and include a 30-day money-back guarantee.

The Enterprise Edition offers the best of both worlds for the corporate developer who needs visual controls for rapid application development, as well as the power and flexibility of dynamic-link libraries for developing core application systems. Including 16-bit Visual Basic controls, 16/32-bit ActiveX controls and 16/32-bit dynamic link libraries (DLLs), the Enterprise Edition is suitable for use with virtually any Windows development environment or scripting tool. A total of  twenty controls and nineteen libraries provide client interfaces for application protocols such as the File Transfer Protocol, Simple Mail Transfer Protocol, Post Office Protocol and Telnet Protocol.
