This article describes how to count the number of instances of a process that are currently running on the system. It is written in C++ for Windows, but could be ported to other systems and languages easily. (Linux, Visual Basic/VB, C, Unix, MacOS) The system just needs to support interprocess semaphores. The idea can be extended to count any resource, such as a thread, file, data structure, or network object.
his one's basically shows that MACROS when used in different compilers can give different results. This one teaches you to analyse C++ code and read it in Assembly and draw Conclusions about the results.
Really interesting if you read it completely...
There is a function gethostbyname for getting the ip address using Winsock. This function will retrieve the ip address details into a variable of type "structure hostent". Read for more info at <a href=http://www.codersource.net/win32_socket_ip_address.html>IP Address Retrieval</a>
C# 2.0 introduces several language extensions, the most important of which are Generics, Anonymous Methods, Iterators, and Partial Types.
The language extensions in C# 2.0 were designed to ensure maximum compatibility with existing code. For example, even though C# 2.0 gives special meaning to the words where, yield, and partial in certain contexts, these words can still be used as identifiers. Indeed, C# 2.0 adds no new keywords as such keywords could conflict with identifiers in existing code.
The new C++ standard is full of powerful additions to the language: templates, run-time type identification (RTTI), namespaces, and exceptions to name a few. This tutorial discusses one of the minor extensions: the new C++ casting operators.
