Project 10 : Employee Intranet with NET This project brings together many of the technologies we learned in other projects to create a company intranet site We have some nice features on this site, including the ability to view how much vacation you have available and make vacation requests, enter and review status reports, and review and modify your personnel information We make use of ASP.NET, ADO.NET,... other projects Setting Up Your Workbench You will need some background knowledge and a small pile of software tools to complete the projects in this book This section will detail exactly what those are Prerequisites This book assumes that you can already create programs with Visual Basic 6.0 and are familiar with Visual Basic NET I am not going to teach you how to use the environment or do very basic. .. is a directory at the root called Projects Underneath that is a folder for each project in the book that contains all the files for each project For example, all the source for project 2 is located at: \Projects\ Project 2 The Web Site A Web site was created for this book to keep you posted on any changes, to let you know about new developments, and to provide additional related information you might... style that we can use as a starting point for all our future applications 1 2 Project 1 The Project We will design and build a set of NET WinForms classes using Visual Basic NET that will encapsulate all the look, functionality, and consistency we need for our enterprise applications There are six classes, or forms, in our collection, which you can use as a starting point for any future applications... seeing how each works and then working through a complete program using that technology The chapters are really projects, complete programs that you can put to use in your own work or other programming We’re covering a lot of material, but the project-oriented approach lets you tackle one issue at a time Organization The projects in the book are all organized the same way Each starts with a statement of... often now referred to as syntax candy Use whatever language you find to be the sweetest 11 12 Project 1 Our Part of the Code I added a few interesting bits that bear explanation Note that there are three controls at the bottom of the form: the OK button, the Cancel button, and the Notify text box An important aspect of any dialog created from this base form is that you may not want or need all these controls... to create your own remote components, configure them to work over an HTTP line, process requests, and ship results back We’ll build a component that logs performance data from your own applications as they execute We’ll also create a class for your own applications that will make it painless to instrument them for performance testing You even get a fancy client program that will get performance data . 91 The Database 91 The Web Service 95 The Client 10 3 Debugging Web Services 11 5 Enhancing the Project 11 6 Project 4: Performance Testing with Remoting 11 9 The Project 12 0 Remoting Overview 12 1 Remote.
