C++ и Static
Рассмотрим употребление ключевого static в языке С++. Думаю кому-то это сообщение будет полезно. Рассмотрим следующие обасти видимости, имеющиеся в С++: Local scope (область видимости - блок) Function scope (область видимости - функция) File scope (область видимости - файл) Class scope (область видимости - класс/структура) В этом случае переменная i будет создана лишь раз, и значение ее будет храниться втчение времени выполнения программы, несмотря на выход за пределы области видимости данного блока. Аналогично дело обстоит с функциями:
BSOD Index
Initial document from the bugcodes.h file in the Windows 7 SDK v7.0 ; Debugging Tools For Windows - dated 17 January 2009; Additional information added as it became verifiable on the web. A BSOD is an error that causes Windows to STOP (hence the name "STOP error"). This is done because the potential exists for damage to your system - and Windows is designed to "fail fast" in order to protect your hardware. STOP error numbers can either be the full number (0x0000007B for example), or in "shorthand" (0x7B is shorthand for 0x0000007B).

Отловил такой баг Раз на несколько тысяч вызовов gethostbyname возвращает NULL. Входная строка (iDomainAddress) всегда одна и та же: Macinrosh.local Ладно, гуглю. Ага, gethostbyname использовать не рекомендуют. Подлатал так
Many Windows C++ programmers get confused over what bizarre data type identifiers like TCHAR and LPCTSTR are. Here, in brief, I will try to clear... QxOrm C++ library: Persistence (based on QtSql Qt library) - Serialization (based on boost::serialization library) - Reflection (introspection)
