Book Description
Subclassing & Hooking with Visual Basic offers developers a unique way to customize Windows behavior.Windows is a message-based system. Every action you request creates one or more messages to carry out the action. These messages are passed between objects and carry with them information that gives the recipient more detail on how to interpret and act upon the message.With Subclassing and the Windows hooking mechanism ("hooks"), you can manipulate, modify, or even discard messages bound for other objects within the operating system, in the process changing the way the system behaves. What kinds of results can you achieve using the power of subclassing and hooking? Here are just a few of the possibilities: Determine when a window is being activated or deactivated and respond to this change. Display descriptions of menu items as the mouse moves across them. Disallow a user to move or resize a window. Determine where the mouse cursor is and respond accordingly. Determine when the display resolution has been changed. Monitor the system for a low system resource condition. Modify or disallow keystrokes sent to a window or a control. Create an automated testing application. Determine when an application is idle. Along with this power comes responsibility; Windows is very unforgiving if subclassing and hooking are used incorrectly. Subclassing & Hooking with Visual Basic demonstrates the various techniques for intercepting messages bound for one or more windows or controls: the intercepted message can be left in its original state or modified; afterwards, the message can be sent to its original destination or discarded.For both VB 6 and VB.NET developers, Subclassing & Hooking with Visual Basic opens up a wealth of possibilities that ordinarily would be completely unavailable, or at least not easy to implement.

Book Description
Getting data across platforms and formats is a cornerstone of present-day applications development. ADO: ActiveX Data Objects is both an introduction and a complete reference to ADO (ActiveX Data Objects), Microsoft's universal data access solution. You'll learn how to easily access data in multiple formats--such as email messages, Access databases, Word documents, and SQL databases--even on different platforms, without spending extra time learning every last detail about each format.Author Jason Roff shows by example how to use ADO with your programming language of choice to save programming time, so you can concentrate on the content and quality of your application rather than the nitty-gritty of specific data formats.ADO: ActiveX Data Objects includes: Chapters dedicated to the Connection, Recordset, Field, and Command objects and the Properties collection A complete, detailed reference listing every ADO object, method, property, and event, in convenient alphabetical order Chapters on ADO architecture, data shaping, the ADO Event Model An appendix containing enumeration tables used by ADO objects and collections, listed alphabetically Brief introductions to RDS, ADO.NET, and SQL ADO: ActiveX Data Objects is a versatile one-stop guide to both the theory and practice of programming with ADO through Version 2.6. The thorough reference section and topic-specific chapters will help you find quick answers about the details of objects, collections, methods, and properties of ADO. And the abundance of practical code examples will give you a good grasp of how to use ADO's strong points most effectively.

Book Description
Completely updated for C# 3.0 and the .NET 3.5 platform, the new edition of this bestseller offers more than 250 code recipes to common and not-so-common problems that C# programmers face every day. Every recipe in the book has been reconsidered with more than a third of them rewritten to take advantage of new C# 3.0 features. If you prefer solutions you can use today to general C# language instruction, and quick answers to theory, this is your book. C# 3.0 Cookbook offers a new chapter on LINQ (language integrated query), plus two expanded chapters for recipes for extension methods, lambda functions, object initializers, new synchronization primitives and more. The new edition is also complemented by a public wiki, which not only includes all of the C# 2.0 recipes from the previous edition unchanged by the release of C# 3.0, but invites you to suggest better ways to solve those tasks. Here are some of topics covered: LINQ Numeric data types and Enumerations Strings and characters Classes and structures Generics Collections Exception handling Delegates, events, and lambda expressions Filesystem interactions Web site access XML usage (including LINQ to XML, XPath and XSLT) Networking Threading Data Structures & Algorithms Each recipe in the book includes tested code that you can download from oreilly.com and reuse in your own applications, and each one includes a detailed discussion of how and why the underling technology works. You don't have to be an experienced C# or .NET developer to use C# 3.0 Cookbook. You just have to be someone who wants to solve a problem now, without having to learn all the related theory first.
