C++ Command Pattern for Network Operations

EBook Description: This is a powerful model because it allows for future changes in device technology without affecting the command code. On a more simplistic level, if we have a cat class, should 'putting out' the cat be part of the cat class? I tend to think that putting out is part of a higher-level operation, which makes it a candidate for a command pattern.

Build a .NET Application on the Oracle Database

Learn the basic yet essential processes involved in building a .NET application that uses an Oracle database.

Using .NET Stored Procedures in Oracle

A step-by-step guide to developing, deploying, and debugging your .NET Stored Procedures in Oracle Database 10g Release 2

The Values That Bind

Improve performance in .NET applications with bind variables and ODP.NET. There are many ways to access data from Oracle databases in .NET applications. In terms of features and performance, however, the Oracle Data Provider for .NET (ODP.NET) is your best choice for connecting .NET applications with Oracle Database.

C++ Chain of Responsibility Pattern: Network Events

The networking problem hasn�t been solved yet�not even nearly! Networks are populated with users who are increasingly hungry for bandwidth and computational resources. I should know�I�m one of them! Just the other day, I downloaded about 200MB of software in an hour of usage on a Wi-Fi network. So, that�s a total of roughly 200 * 8 * 1024 * 1024 bits in 3600 seconds, or a bandwidth requirement of 0.466Mbps. This download rate was probably limited more by the Web sites concerned than the local network, which boasted a link speed of 11Mbps.

Drawing and Printing in C++ with wxWidgets

This chapter introduces the idea of the device context, generalizing the concept of a drawing surface such as a window or a printed page. It will discuss the available device context classes and the set of 'drawing tools' that wxWidgets provides for handling fonts, color, line drawing, and filling.

Adding an Easy File Save and File Load Mechanism to Your C++ Program

Why waste your time figuring out an algorithm for storing things in a file? And why spend time debugging the code? Let the Boost library do it for you. Saving your data to your own custom-made file formats is easy with the help of the Boost serialization templates. Jeff Cogswell shows you how to save the data and read it back in with ease.

Accessing a MySQL Database from a C++ CGI Program

If you want to access a MySQL database through CGI, C++ is a great option. Sure, you can use other languages such as PHP or Perl, and they might be easy to use, but C++ has the advantage of being fast, powerful, and fully compiled, thereby hiding your original code. In this article, Jeff Cogswell shows you how you can write CGI programs in C++ to access a MySQL database
