I want to detect keypress in C++ and i need to use Windows System Call. So, i did some research and this is what i got using Hooks and Message:
#include
The events are posted to the active window. Console windows are owned by the console subsystem, csrss.exe, and it receives the events, then translates them to characters and puts them in the console object which is your application's stdin
.
If you want to process events the Win32 GUI way, you should use a Win32 window (e.g. RegisterClass
and CreateWindow
), not a console window.
If you just want the callbacks to work for a certain period of time, you can use an alertable wait such as SleepEx
or MsgWaitForMultipleObjects
, which accept a timeout.
