Making .exe files with Linux
Making .exe files with Linux
CodeCall Intro: My tutorial today will be about how to compile an executable (.exe) for Windows on a Linux system. This will be a method to cross-compile to Windows without requiring a virtual machine or emulation on your end and can speed testing when required.

Command Line Arguments
Command Line Arguments
This tutorial will show you how to eliminate the needs for menus and complex user interactions with your C++ programs. Using the information presented here will allow you to create much simpler input systems for your programs.

But It Worked On MY Computer...
But It Worked On MY Computer...
Portability is becoming increasingly more important nowadays with the 32-/64-bit dichotomy. Writing portable code means that something you write will compile and run on a variety of different systems with no modification to the source code. Just because it compiles doesn't mean it'll run properly. Here I will outline some common mistakes and assumptions that make code unportable, and how to avoid them.

Intro to Intel Assembly Language: Part 8
Intro to Intel Assembly Language: Part 8
Hello, and welcome back to my long-overdue eighth part of my tutorial series. If you haven't checked out the previous seven parts, you might want to unless you know what you're doing. Anyway, in this part I'll be going over some Linux system calls you can make in your assembly programs.

Intro to Intel Assembly Language: Part 9A
Intro to Intel Assembly Language: Part 9A
"Hi! Welcome back to my latest installment of my series, Introduction to Intel Assembly Language. In this issue we're going to start getting into some really fun stuff--graphics. Because this involves writing directly to memory, and most operating systems won't let you do that*, we're going to need to emulate our code on a virtual machine."

Compile code for the PIC18F4520 using TinyBld and SDCC
Compile code for the PIC18F4520 using TinyBld and SDCC
This is a little article about how I finally got TinyBLD (The Tiny Bootloader) working on my PI18F4520. Full source and compiled hex files are included. The tutorial is based on Ubuntu, but it should be a piece of cake on other Debian-based systems, as well as being reasonably easy on other systems.

Lessons on development of 64-bit C/C++ applications
Lessons on development of 64-bit C/C++ applications
The course is devoted to creation of 64-bit applications in C/C++ language and is intended for the Windows application developers who use Visual Studio 2005/2008/2010 environment. Developers working with other 64-bit operating systems will learn much interesting as well. The course will consider all the steps of creating a new safe 64-bit application or migrating the existing 32-bit code to a 64-bit system. The course is composed of 28 lessons devoted to introduction to 64-bit systems, issues of building 64-bit applications, methods of searching errors specific to 64-bit code and code optimization. Such questions are also considered as estimate of the cost of moving to 64-bit systems and rationality of this move.

Windows Internals Windows Programming Tutorial
Windows Internals Windows Programming Tutorial
The presentations discuss on Windows Internals and Windows Programming. The list of topics are mentioned in the presentations. I would keep making them besides the many other efforts on my web-site. Learn with me on this very useful system and on programming it.

Build Tetris Application Using VisualC++
Build Tetris Application Using VisualC++
This tutorial has only four main code examples, but rather extensive ones. They are presented in increasing complexity order. The simplest one is the Tetris application, which deals with graphics, timing, and message handling. The Draw application adds a generic coordinate system and introduces more complex applications states. The Calc application deals with formula interpretation and graph searching. Finally, in the Word application every character is allowed to hold its own font and size, resulting in a rather complex size and position calculation.

Commands for executing a C++ program in Unix OS - C++
Program is created with the help of a text editor, which is either ed or vi in the case of UNIX operating systems.

Using vector instead of arrays to prevent most of memory leaks
Using vector instead of arrays to prevent most of memory leaks
Most of beginners define arrays of limited size such as:

int array[100]; // array that can accomodate 100 integer values

These are ok, but your requirement may be different, and you want your application to determines the size of array at runtime, so if your requirement is to use 10 elements only, that means 90 are unused but memory is still allocated for them while application is running. On other hand your application requires 110 elements to be saved, the last 10 will be unallocated spaces if array size is 100, and access to unallocated memory address may result in applciation crash and/or system level damage.

Lesson 1: Transforming Numerical Systems
Lesson 1: Transforming Numerical Systems
This is the first lesson I wrote. Its purpose is to introduce you to the world of programming, showing you the way computers think or archive data. Please be patient and read through the whole lesson carefully in order to fully understand showed examples and calculations. I understand you can't wait to start using the code, but believe me these general foundations are somehow necessary to fully understand next tutorials and lessons I'll provide you with.
