Through the series of Articles, we are learning how to draw on MFC dialog using OpenGL. In our previous article “OpenGL – How to draw on MFC dialog? – Linking opengl32.lib“, we learned how to link opengl32.lib to our Project. We have executed the Project and no drawing was shown on the MFC dialog; this […]
OpenGL is used to render 2D and 3D vector graphics. We have briefly discussed OpenGL in our previous article “OpenGL – Open Graphics Library – An introduction“. OpenGL is a cross-platform API; that means, it has generic functions which are NOT specific to any particular platform, which enables it to run on any platform. So, […]
OpenGL (Open Graphics Library) is an industry standard API used to render 2D and 3D Vector graphics. It is so popular because, it is a portable, cross-language and cross-platform Application Programming Interface written in C language. OpenGL was initially developed by SGI (Silicon Graphics Inc.,) and released to the market in the year 1992. This […]
We learned that arrays are the sequence of elements that allows for storing the same data type elements. But, if we want to store different data type elements there are different ways to do this; and we are going to cover one of them in this article. An array of structures in C We know […]
Unions are another useful types in C language, where all of it’s members starts at the same location in memory. That means, all members of the Union, have the same address; whereas, members in Structures have different addresses. This unique quality of the Unions, saves the memory usage. Defining an Union in C By using, […]
Arrays are sequences of elements of the same data type. In C, arrays have boundaries; the lowest boundary is always 0 (zero) and the highest boundary depends on the size allocated to the array. Arrays are very useful especially when dealing with large data. Array declaration in C In C, declaring an array is simple […]
Dealing with the data is an important feature, every programming language has to consider. Hence we are allowed to define different data types of variables to store & retrieve the data with ease. But, some times, these data types (primitives or predefined data types) are not enough to our programming need; and we need complex […]
Have you ever observed; when we open a file in Windows, it will open in an Application that supports the file? When you open a media file to play the music or a video, it will NOT open in a Notepad, right? How does the Operating System knows, the Application in which the file has […]
Windows Services are the Applications which are running in the background to do specified operations. Windows provides Graphical User Interface to manage the Services. And also it provides some command line tools to manage the Windows Services from the command prompt. Through this Article, we are going to discuss one of the command line tool; […]
Windows provides commands to rename the file or folder from Windows command prompt. Through this Article we will discuss on renaming files and folders from Widows command prompt. REN command – Rename files or folders REN or RENAME command is used to rename the files or folders in Windows Operating System. We can use this […]
