Function Prototypes

Learn about the C++.People often ask about startyng with C++ or move a project or development team to the language.There are many answers to this question. One of the simplest and best is to begin using C++ as a "better C".This term doesn't have a precise meaning but can be illustrated via a series of examples.We will cover some of these examples in forthcoming issues of the newsletter.

Classes and Object-Oriented Programming in PHP

In this tutorial introduce you to the concept of Classes and Objects in PHP. To put it simply, an Object in the context of programming languages is a data structure which can contain any number of variables and functions all held together under a Class name. This Class can then be created in the normal scope of the code and stored inside a new variable, and multiple copies of this same class can be created. This allows for an even greater level of code encapsulation, allowing more complexity to be accessed from simple commands.

Working with dates and times in PHP

When developing more complex PHP sites, especially forums, discussion boards and blogs where date and time functions are important, you’ll regularly encounter situations where you need to display and manipulate values based around the current date and time. PHP includes a range of functions which can help you to easily format and adjust your date and time displays to suit your needs. In this tutorial, we’ll look at some easy ways to display calendar information for your visitors.

ARRAYS in C-Sharp

When defining variables you can choose between scalar number and arrays. Arrays in C# are declared by adding a set of square brackets to the end of the variable declaration. All members of an array must be of the same type. You cannot have different types in an array.

Binary Serialization in C#

In a previous tutorial we talked about serialization and the various option for formatting its data output. In this document we will talk about binary serialization. Binary serialization is used for communication between .Net applications and is not a human-readable format. Windows relies on serialization for many important tasks such as remoting and copying items to the clipboard.

Collections in C#

Sometimes is necessary to hold more than one object in your program as an object, a part, of a bigger collection. For example, one might want to store information about each book in his possession. So, a collection which represents these books must be defined. The C# language and the .Net environment offer you numerous techniques for implementing these kinds of collections in your code. One of those techniques is by using a collection structure.

Exception Handling in C#

Every self-respected programmer should include exception handling techniques. Sometimes your application will generate an error. Regardless of who was responsible for this error, the programmer or the user, it is up to the first to include the necessary exception handling techniques to keep his/her program from crashing. The .Net environment provides useful techniques for avoiding disastrous errors such as try-catch statements and user-defined exceptions.

Graphics with C#

The .Net provides classes for the programmer to be able to work with graphics. This technology is called GDI+ and controls custom drawing on the screen. These classes instruct the graphics device driver to send the appropriate output on the screen. This tutorial is an introduction to the GDI+ technology in order to start drawing simple objects on screen.

Regular Expressions in C#

A regular expression’s use is for finding substrings in a large string expression. It supports the use of various wild cards and other very useful techniques for performing the required actions. The namespace System.Text.RegularExpressions contains a number of classes associated with regular expressions.

Sequential Lists: The Queue and Stack Class

Sequential lists are collection of objects that can be entered or extracted in a sequential way. They don’t provide access to objects in the middle on the list. You can only access a specific object each time you extract it. The two classes named “Queue” and ”Stack” which belong to the “System.Collections” namespace provide you with this kind of functionality, each of them in a slightly different way. The Queue class offers you access to the first object on the list, whereas the Stack class offers you access to the last object on the list. By first and last we mean the first and last object that entered the list. So, the Queue class is a First-in, First-out collection(FIFO Collection) whereas the Stack class is a Last-in, First-out(LIFO Collection). In this tutorial you will create and use both classes to see how they behave when entering and extracting data. You will usually work with such collections with temporary and disposable data. For a more permanent use, arrays provide much better functionality.

Serialization in C#

Many applications need to communicate with other applications to exchange data or store data in the hard disk. The .Net framework has made these tasks quite simple by including the serialization technique, which can convert objects into binary, SOAP(Simple Object Access Protocol ) or XML documents in order to provide a convenient way for storing and transferring information. Besides the three mentioned format types you can also implement custom serialization to take complete control of the serialization output.

Threading with C#

Multi-core processors are new standards on the user’s hardware. By taking advantage of the multi-processing capabilities of these machines you can achieve significant performance upgrade with some minor changes in your code. When an application does not make use of threading techniques it is wasting valuable resources. This tutorial will cover the basic threading concepts and threading methods and properties.

XML Serialization in C#

Serialization is the process of persisting an object to disk. Another application can deserialize your object and it will be in the same state it was before the serialization. This tutorial talks about XML serialization. The namespace containing classes and methods suitable for such a serialization is System.Xml.Serialization.

Sending Emails in C#

The process of sending emails is a simple one. However, because of its dependence on many factors things can become complicated. For example, if the server is not responding, the user should be able to choose whether to stop or not.

Introduction to Open GL in C#

OpenGl is an API similar to direct3D. However, OpenGL (Open Graphics Library) is not supported by Microsoft and is a cross-language, cross-platform API used for writing applications that produce 2d or 3D graphics. Over 300 functions are implemented in this API which can help you draw complex 3D scenes from primitive data such as polygons and triangles. Mesa 3D is an open source library API which is also compatible with the OpenGl protocol. OpenGl aims at two key goals: 1. To present to the programmer a uniform API that hides the complexities of interfacing with different 3D accelerators. 2. To hide the different capabilities of hardware platforms. OpenGL converts primitives into pixels that are depicted on your screen. Primitives can be polygons, triangles or lines. The transformation is accomplished by a graphics pipeline.
