PowerTCP Winsock for ActiveX: Controls for TCP, UDP, Daemon, DNS, Ping, and RAS provide the building blocks you need for basic Internet application development.

These easy-to-use controls offer superior buffer management, the use of variants supporting String and Byte-array data, and optional blocking, making this tool exceptionally complete and versatile.

• Intuitive On-line Help
• TCP
• Daemon
• UDP
• Ping
• RAS
• DNS
• Multicast

Potential Uses/Applications:

• Build a personal stock quote application.
• Create a multi-threaded server.
• Write a custom client/server protocol.
• Create dynamic pages using a TCP Control on a Cold Fusion server.
• Develop inter-process communications.
• Build an lpd print server.
• Broadcast UDP packets to check for software licensing.
• Create a chat program using multicast capabilities.
• Use ping to continually check status of company network devices.

Sample Projects:

• Web Server a simple multi-threaded VB application serves up web pages
• TCP Client shows non-blocking interactive operation
• TCP Blaster shows blocking interactive operation
• UDP Client shows how to build an interactive "chat" utility
• RAS Client shows dial-up operation
• Ping Client ping any host on your network
• DNS Client demonstrates interaction with any Domain Name Server
• WebAlive compares the performance of 2 web servers (VB only)
• Chat Client uses a simple protocol and multicast datagrams to join chat sessions

Benefits & Features:

• Advanced Debugging
• Automatic error reporting through the COM interface
• Easy to use in blocking or non-blocking environments
• Advanced in-bound and out-bound buffering
• TCP Search Method supports variable length records and line processing, eliminating the need to search for termination characters and simplifying buffer management
• TCP Fill Method supports fixed length binary records, simplifying buffer management and reducing the code needed to send and receive binary structures
• UDP supports raw datagrams, providing the ability to access advanced protocols like ICMP
• UDP supports multicast datagrams, allowing you to send and receive streaming protocols, and to easily construct chat programs
• RAS can be invisible or visible, simplifying user configuration
• DNS Control bypasses Winsock system services, so you can query ANY Domain Name Server on the Internet
• Ping Control will confirm the presence of any host on the Internet, even if hosted server applications are not responding
• Controls can operate on separate threads, so Server Applications can be written using apartment model multi-threading features
