Free socket layer software for windows

Socket Master 1.00.56 is an attractive game where you can debug network sockets by enabling them to open a listing socket. It allows users to create a listening tcp/udp socket and an outgoing tcp/udp socket for testing embedded network connectivity during the development cycle. Received and transmitted data can be entered in string form, decimal, or hex notation.

This allows non printable characters like 0x00 or 0xff to be sent or received, unlike similar tools which allow only printable ascii characters to be transmitted and received. Great for debugging all types of network enabled applications.

ODBC Socket Server is an open source database access toolkit that exposes Windows ODBC data sources with an XML-based TCP/IP interface. Allows databases such as MS Access to be accessed across TCP/IP networks; or Linux/Macintosh/UNIX access to any Windows Database. Clients for COM, C++, Perl, PHP included, all source code provided.

An open source SDK for plugin development. The SPL (Simple Plugin Layer) library was designed to be an open source SDK for plugin development.
With SPL you can extend every application written in C/C++ to use your own plugins, SPL will do all the managing, loading and unloading stuff for you. Additionally, the whole framework is fully multi-platform capable, so you dont have to develop multiple versions of the same plugin for platforms provided by SPL.
Main features:
- Open Source, uses LGPL license
- Free, costs absolutely nothing, even for commercial use
- Platform independent architecture
- Implementations for Linux, Solaris 8 and Win32 available, more platforms coming soon ...
- Documentation in various formats, powered by Doxygen
- Optional macros for fast and easy plugin development
- Variable plugin arguments for extensible APIs
- Thread-safety for complex applications
- Uses STL library for stable and portable containers
- Object-oriented design, easy to extend
- Customizable to 32- or 64-bit systems
- Completely written in C++, no other dependencies except STL needed
- Buildable as static/shared library or DLL (only Win32)
- Various examples for all platforms explaining the development step by step
- Source code written in uniform style
System requirements:
- Microsoft Visual Studio 6.0
- Microsoft Visual Studio 2002
- Microsoft Visual Studio 2003
- Microsoft Visual Studio 2005

Allows you to open active and passive socket connections The Direct Socket Control application was designed to be a simple tool that allow you to open active and passive socket connections (TCP and UDP) to other hosts and to send and receive data from them.
Additional modules - e. g. a forwarder tool and a "programmable" bot make it even more useful.
This program is actually a reimplementation of a rather old and buggy Visual Basic tool ("Winsock Tools") in Java.
System requirements:
- Java Runtime Environment 1.4 or higher
