.NET Windows Forms are a new programming paradigm introduced with Microsoft's .NET initiative. Windows Forms are very similar to Web Forms, which allow programmers to build complex Web application interfaces easily, sharing the same underlying framework and programming concepts. Windows Forms, however, are used for the Win32 platform, instead of the Internet, and allow programmers to build traditional Windows desktop-based applications structured around .NET. Sams Teach Yourself .NET Windows Forms in 21 Days covers all the major aspects of Windows Forms necessary to build professional, functional applications. This book follows the tried-and-tested 21 Days tutorial model to guide the reader through Windows Forms. It features code examples and tips for programmers migrating from pre-Windows Forms Microsoft technologies. The reader will be introduced to the many controls available for .NET Windows Forms and how to build them, learn how to create events and event handlers, explore ADO.NET and methods to retrieve data from dynamic data sources, and learn how to take advantage of the Internet and Internet Explorer from their .NET Windows Forms applications. As readers advance through the tutorials, they progress toward more advanced topics and projects by creating simple graphical applications and enhancing existing ones, learn how to integrate with other .NET applications, use Web services, build Windows services, build Windows Forms controls, create multi-threaded applications, work with COM and COM+ configure and deploy .NET Windows Forms, and how to de-bug .NET Windows Forms.

This book is the definitive guide to SQL*Plus. If you want to take best advantage of the power and flexibility of this popular Oracle tool, you need this book. SQLPlus is an interactive query tool that is ubiquitous in the Oracle world. It is present in every Oracle installation and is available to almost every Oracle developer and database administrator. SQLPlus has been shipped with Oracle since at least version 6. It continues to be supported and enhanced with each new version of Oracle, including Oracle8 and Oracle8i. It is still the only widely available tool for writing SQL scripts. Despite this wide availability and usage, few developers and DBAs know how powerful SQL*Plus really is. This book introduces SQLPlus, includes a quick reference to all of its syntax options, and, most important, provides chapters that describe, in step-by-step fashion, how to perform all of the tasks that Oracle developers and DBAs want to perform with SQLPlus -- and maybe some they didn't realize they COULD perform with SQLPlus. You will learn how to write and execute script files, generate ad hoc reports, extract data from the database, query the data dictionary tables, customize your SQLPlus environment, and use the SQL*Plus administrative features (new in Oracle8i). This book is an indispensable resource for readers who are new to SQL*Plus, a task-oriented learning tool for those who are already using it, and a quick reference for every user.
