Threads play a major role in applications programming today. For example, most Web servers are threaded, as are many Java GUI programs. Here are the major settings in which using threads has been founded convenient and/or efficient:
• Programs with asynchronous events:
Here the program must be ready for various events, but does not know the order in which they might occur. For example, in Sections 3.1 and 3.2, we have a network server connected to several clients. The server does not know from which client the next message will arrive. So, we have the server create a separate thread for each client, with each thread handling only its client.

Hey! Socket programming got you down? Is this stuff just a little too difficult to figure out from the man pages? You want to do cool Internet programming, but you don’t have time to wade through a gob of struct s trying to figure out if you have to call bind() before you connect(), etc., etc. Well, guess what! I’ve already done this nasty business, and I’m dying to share the information with everyone! You’ve come to the right place. This document should give the average competent C programmer the edge s/he needs to get a grip on this networking noise.

MySQL is a popular database with more than 4 million users. It is one of the fastest relational databases in the market. Many companies are using it to support their websites, data warehouses, and business applications. MySQL was developed by a Swedish company named MySQL AB. The product is distributed under GNU General Public License (GPL). It can support multiple users concurrently on the network. Students can connect to a MySQL database server standalone on their own computer or from the network. You can download it free from http://dev.mysql.com/downloads/mysql/4.1.html. MySQL runs on Windows, Linux and Solaris. This tutorial demonstrates using MySQL from the Windows operating system.

This guide assumes that the reader has a basic understanding of what ArcGIS and the .Net framework is, as well as a rudimentary understanding of how object oriented programming works. For more information about .Net and object oriented programming, follow the links in Appendix B.

In order to program with ArcGIS there are two products that you will need to have installed on your computer. First, you must have either ArcGIS Desktop, ArcGIS ArcInfo or else have the ArcGIS Engine installed. Once these one of these are installed you will be able to run the code you compile in the ArcGIS environment. The other ArcGIS product you need is the Developer Tools for Microsoft.Net that provides access to the .Net framework and the functions that ESRI has made for .Net as well as the Developer tools that install an API for ArcObjects. It is also important to make sure that your software is up to date, which you can do by checking the ESRI website to see if there are updates or service packs for your software (this tutorial was written using ArcGIS 9.2 Service Pack1).

If you are new to programming in the Java TM language, have some experience with other languages, and are familiar with things like displaying text or graphics or performing simple calculations, this tutorial could be for you. It walks through how to use the Java® 2 Platform software to create and run three common types of programs written for the Java platform—applications, applets, and servlets. You will learn how applications, applets, and servlets are similar and different, how to build a basic user interface that handles simple end user input, how to read data from and write data to files and databases, and how to send and receive data over the network.
