The course is devoted to creation of 64-bit applications in C/C++ language and is intended for the Windows 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.

Program errors occurring while porting C++ code from 32-bit platforms on 64-bit ones are observed. Examples of the incorrect code and the ways to correct it are given. Methods and means of the code analysis which allow to diagnose the errors discussed, are listed.

This article is the most complete collection of examples of 64-bit errors in the C and C++ languages. The article is intended for Windows-application developers who use Visual C++, however, it will be useful for other programmers as well.

We develop a static analyzer called PVS-Studio. This is a code analyzer capable of detecting errors in C/C++ software. When we communicated with you, I must have told you that this analyzer detects 64-bit errors and integrates only into the Visual Studio environment.

This project supports extending (hooking) unmanaged code APIs with pure managed ones ... 32- and 64-bit kernel mode hooking is supported as well as an unmanaged user-mode API which allows you to hook targets without requiring a NET Framework on the customers PC.

The article concerns the peculiarities of Visual C++ compiler's behavior when generating 64-bit code and possible errors relating to it.
