Modern versions of OS impose on executable code of restriction, connected with safety requirements. In such conditions use of the mechanism of exceptions in the injected code or, say, in manually the projected image can become a nontrivial task if not to be aware of some nuances. In this article it will be a question of the internal device of the yuzermodny manager of exceptions of Windows OS for the x86/x64/IA64 platforms, and also options of implementation of a bypass of system restrictions will be considered.

How to pass elephant through eye of a needle. Processing of the maximum data volumes for the minimum time

2 years, 1 month ago


That only you will hear from apologists of the same Java or C# about development on C/C ++! Allegedly this language has become outdated and in it nobody writes. Here only when it is required to create no latency or low latency service or it is necessary to save memory and runtime of bottleneck of processing of large volumes of data then resort for the help to? the archaic? to developers on C/C ++. Simply because these children are able to manage manually memory and perfectly represent that for stuffing at this or that high-level operation. Today our task? to become a step closer to these children.

Serialization, sir! Today for dinner the byte porridge cooked from C objects ++

2 years, 1 month ago


Variables and types are good while we are in logic of the program C ++. However sooner or later it becomes necessary to transfer information between programs, between servers or even it is simple to show types and values of variables to the homo sapiens. In this case we should conclude the bargain with the spiteful Serializer and to pay off with productivity of the code. In the last lecture of Academy C ++ we at last have reached the chief boss against whom it is necessary to learn to win minimum loss the speed of execution of code. Have gone!

Revelations of the metaprogrammer. We program program code at compilation stage, we use templates C ++ for not sample solutions

2 years, 2 months ago


It is possible to call templates the most important difference and primary benefit of language C ++. Opportunity to create algorithm template for different types without copying of code and with strict check of types? it is only one of aspects of use of templates. The code of specializations of template is under construction at compilation stage, and it means that the behavior of the created types and functions can be managed. How here to keep from opportunity to poprogrammirovat the compiled classes?

Metaprogramming becomes so integral part of writing of code on C ++, as well as use of standard library which part is created for use at compilation stage. Today we will bring into world library of safe reduction of scalar types C ++, metaprogramming templates!
