Very comprehensive collection of information about 64-bit programming:
By Andrey Karpov,
In this post I’ve collected a lot of links on the topic of 64-bit C/C++ software development. These include my articles and articles by my colleagues in the sphere of developing safe and efficient 64-bit code; FAQ’s and a training course. There are also many reviews of third-party articles on 64-bit software development. Enjoy yourself studying the materials.

2. Lessons on development of 64-bit C/C++ applications
Main page: http://www.viva64.com/en/l/
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.
The contents of the course:
- Lesson 01. What 64-bit systems are.
- Lesson 02. Support of 32-bit applications.
- Lesson 03. Porting code to 64-bit systems. The pros and cons.
- Lesson 04. Creating the 64-bit configuration.
- Lesson 05. Building a 64-bit application.
- Lesson 06. Errors in 64-bit code.
- Lesson 07. The issues of detecting 64-bit errors.
- Lesson 08. Static analysis for detecting 64-bit errors.
