    From Press Release

    Xceed Releases Winsock Library

    Xceed Software, Inc. announces the release of the Xceed Winsock Libraryｪ v1.0, a new COMｪ / ActiveXｪ library that offers effortless access to the complete Winsock 2 networking API. The library allows Windowsｪ developers to write efficient, scalable networking code for their applications without spending weeks or months developing the low-level code and expertise needed to use the powerful Winsock 2 API.
    "While a simple COM wrapper library for Winsock 2 would already have been a breath of fresh air for developers, the Xceed Winsock Library is much more than that." said Odi Kosmatos, head of component development at Xceed Software. "This library is the Winsock 2 lion tamer. It buffers data, manages thread pools and connections, solves OS compatibility issues and eliminates headache-inducing Winsock 2 peculiarities. Just what the doctor ordered."
    The Xceed Winsock Library exposes all the flexibility provided by the Winsock 2 API, including support for protocol independence, quality of service and multicasting, while offering a simplified object model and a built-in multithreaded low-level I/O engine.
    The library's low-level engine takes full advantage of Winsock 2 optimization features such as overlapped I/O and completion ports, when available. Applications using Xceed Winsock Library are therefore using pre-optimized, pre-tested networking code and are ready to handle large loads without overtaxing the systems they run on.
    The library comes with various COM interfaces and supports most 32-bit languages including Visual Basic, Visual C++ and Delphi.
    Winsock and Winsock 2
    Winsock is an open-standard network API for Microsoft Windows developed by over 30 network hardware and software providers, including Microsoft, Novell, IBM, Sun, 3Com, HP and DEC. Winsock 2 is an extension to Winsock that adds the advanced functionality required in order to work with emerging network technologies.

    Write efficient and scalable networking code without spending weeks or months trying to work directly with Microsoft's monster Winsock-2 networking library.

    Xceed Winsock Library

    [Network Programming Made Easy]

    The Xceed Winsock Library is a COM / ActiveX library designed to offer effortless access to the complete Winsock 2 networking API. It allows you to write efficient, scalable networking code without spending weeks or months developing the low-level code and expertise needed to properly use Winsock 2's powerful API.

    [No more protocol-specific code!]

    The Xceed Winsock Library is the only COM library that lets you write protocol-independent networking code. That means that your applications can work with different protocols as needed - including new and emerging protocols such as IPv6. Gone are the days of IP, UDP or TCP-only programming.

    In addition, the Xceed Winsock Library is the only solution that supports Quality Of Service, Service Advertising and rooted or non-rooted IP Multicast. Not to mention that it allows access to the impressive list of Winsock 2 protocols.

    [Use any Winsock 2 protocol]

    IP protocols (including IP, TCP, UDP, ICMP, PUP, IGMP, GGP, IDP, ND)
    IPv6 protocols
    IPX, SPX, SPX II
    NetBios protocols
    DECnet
    ATM ptorocols
    ISO protocols (TP0 to TP4, CLTP, CLNP, X.25, ES-IS, IS-IS)
    Appletalk protocols (RTMP, NBP, ATP, AEP, RTMPRQ, ZIP, ADSP, ASP, PAP)
    Banyan Vines (IPC, Reliable-IPC, SPP)

    [Write your own high-level protocols]

    With the Xceed Winsock Library, you can write your own high-performance HTTP server, FTP server, SMTP server, etc. To help you get started quickly, the trial version includes a sample HTTP server for VB, Delphi and VC++. You'll also find chat samples, a multiplayer game, name server, and more!

    Xceed Winsock Library technique longue

    [What languages are supported?]

    Multiple types of COM interfaces are provided, allowing efficient use of the library by a wide variety of languages, including Visual Basic, Delphi, Visual C++ and VBScript.

    [More than just a pretty wrapper]

    The Xceed Winsock Library doesn't stop at just providing intuitive COM interfaces for Winsock 2. It provides an optimised, multithreaded low-level I/O engine that transparently takes care of a variety of tasks that normally need to be coded.

    [No more I/O coding or Winsock 2 books!]

    The library's low-level engine buffers data, manages thread pools and connections, eliminates OS compatibility issues by emulating NT features when running on Win 95 and 98, and hides Winsock 2 method call peculiarities with efficient workarounds. With the Xceed Winsock Library, there's no more need to suffer through hard-code Winsock 2 coding ever again!

    [High-performance? Definitely.]

    The library's low-level engine takes full advantage of Winsock 2 optimization features such as overlapped I/O and completion ports, when available. Applications using Xceed Winsock Library are therefore using pre-optimized, pre-tested networking code and are ready to handle large loads without overtaxing the systems they run one.

    [High-level functions, efficient events.]

    What about if you simply want to send or receive a file? No problem. The library will take care of that operation with a single method call. You can send and receive byte arrays and Ansi or Unicode strings, too. Not interested in receiving certain events? The library will trigger only events you're interested in, and eliminate the overhead of all the others. For the ultimate in efficient event notification, The Xceed Winsock Library offers event handling through "implemented interfaces" instead of traditional COM events.

    [Multi-threading]

    Like all Xceed Software components, the Xceed Winsock Library is written entirely with threadsafe code and supports both the single-threaded (STA) and multi-threaded (MTA) appartment models.The library has been optimized and tested on both single and multiple processor machines, and is perfectly suited for use in environments running hundreds and thousands of simultaneous connections or transfers.
