Is there a quick way to clear “frequent” items list?

Posted on August 16, 2013 by tetra

Answer:

Open “Taskbar and Start Menu Properties” by right clicking the start menu button\properties when this opens you have the ability on the Start Menu tab to change this. If you just want to clear it for now uncheck under Privacy the bottom one which will take this off and the check it again and it will start to build the list again.

scope operator

Posted on July 22, 2013 by tetra

:: <- 전역의 범위를 지정

::variable; // 전역변수를 우선 지정함

class::function();

여기서 namespace 개념이 파생됨.
