OpenCV is an open source computer vision library developed by Intel. This library is written in C/C++ and it has lot of very powerful image processing features. This tutorial describes how to install OpenCV and how to configure Visual Studio 2005 to work with OpenCV
C++ Basics - Great tutorial for beginners on using C++
The GNU Debugger (gdb) is the most popular open source debugger in use. Learn how the Eclipse C/C++ Development Tooling (CDT) talks to the GNU Debugger. This concrete example of CDT-debugger interaction should be helpful for anyone wishing to interface a custom C/C++ debugger from CDT.
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.
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.
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.
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.
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.
In this tutorial we will present the basic steps for drawing graphics. Something that most programmings find interesting with C# for the beginning of anything related to graphics programming such as Game Development.
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 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.
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.
A C# program can be written either in a text editor or in an integrated development environment (IDE). The later provides access to various other features. In this tutorial we examine the Visual Studio 2008 IDE in order to illustrate various concepts of a C# windows program.
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.
