[Transfer] CEvent of MFC

Event is used to synchronize different threads. Once a thread ends its use of a global resource, it notifies others that it is available for use by calling SetEvent. If this is deleted, other threads will be blocked When ::WaitForSingleObject(pEvent->m_hObject, INFINITE); is called in a thread, it will wait on this sentence without proceeding. At […]

[Transfer] OPenGL MFC drawing

1. Introduction GDI draws through the device handle (Device Context, hereinafter referred to as “DC”), while OpenGL requires a drawing environment (Rendering Context, hereinafter referred to as “RC”). Each GDI command requires a DC to be passed to it, but unlike GDI, OpenGL uses the current drawing context (RC). Once a current RC is specified […]
