Viewing connection times with PowerTCP TraceRoute Client.

PowerTCP Sockets for .NET contains easy-to-use TCP and UDP components that can help you create Internet client applications with only a few lines of code and convenient Events. The Ping component enables server verification using ICMP, UDP, and TCP, while the Trace component conducts an asynchronous Trace Route for fast response. The DNS component is not dependent on OS services, allowing for the use of any DNS server. Advanced SegmentedStream technology allows for data to be received up to a specific delimiter or fixed-length, which is ideal for building custom TCP-based protocols

Updates in V4.4

  • A new DNS component that enhances what is available in the .NET Framework. Lookup MX records, select the DNS server to use, and specify local endpoint to bind to.
  • Connect methods have been updated to take a serializable Session object as a parameter, facilitating the saving of state information within an application.
  • AuthenticateClient and AuthenticateServer methods have been updated to take a serializable Security object as a parameter.
  • ReadToDelimiter, ReadToCount and ReadToEnd methods have been updated to throw a new DataException, which provides any data read up to the exception.

About Dart Communications

Dart Communications was founded in 1994 for the specific purpose of creating quality components designed to support Internet communication development. Dart's development teams carefully design each component for ease-of-use and maximum range of effectiveness for both beginners and advanced developers alike. The results are tools that function in many development environments, such as .NET, Visual Basic, Visual C++, PowerBuilder, ASP, Delphi, C++ Builder and Office 97/XP. Companies such as Chase Manhattan Bank, Blue Cross/Blue Shield, America Online, Compaq Computer, American Express, and thousands of consultants and individual project teams rely on Dart's quality code, breadth of capability, and customer service. Designed in object-oriented methods, the tools easily make the change from ActiveX to .NET framework, allowing these users to transition the product as appropriate for their own environments.
