I’ve been using JQuery for a while now and really agree with its tag line that it’s the “The Write Less, Do More, JavaScript Library”. We’ve also got this code for dragging and dropping table rows that has proved very popular, so it seemed natural to combine the two and wrap [...]
This article describes how we used Groovy to create a DSL for the clauses in a rules engine. We have been collaborating in the development of an “expert system” application for KnowledgeBench Ltd. This application uses a forward chaining rules engine to provide a “smart” system capable of [...]
Summary: This article tells you how to implement drag and drop for HTML tables in Javascript. You can download the source here and play with the demo here.
Updated: now copes with multiple tables on the same page, non-drag and non-drop rows (such as headers) and embedding form elements. Also [...]

One of the problems when writing JavaScript is that you don’t have a development environment with a debugger to find out what’s going on. For Microsoft platforms, there is the Microsoft Script Debugger which provides some help, but [...]
The aim of this project was to be able to get the groups that an NT user belongs to using ADSI (Active Directory Services Interface) and make this available in Java. In the first article we described how to get ADSI information using VBScript, JScript and then C++. Now we show how to wrap [...]

This first article describes how to get ADSI information using VBScript, JScript and then C++. It shows how the different languages make it [...]
If you have access to Visual C++, then compiling C++ to produce an EXE or a DLL isn’t particularly hard. If not, then you either have to use gcc or there is an excellent free C++ compiler provided by Borland. You can download freecommandlinetools.exe
The aim of this project is to generate an SQL script from an existing database such that the tables and data can be recreated exactly as it was.
