How can I check if a key is down asynchronously? Like, instead of getchar(), which stops program execution and requires you to hit enter to input the variable. My Geekcode: "GCS d s: a14 C++$ P+(++) L+ E-- W+++$ K- w++(+++) O---- M-- Y-- PGP- t X R- tv+ b++ DI+(+++) D- G e* h!" Decode my geekcode! Geekcode.com

GetAsyncKeyState()

#define KEYDOWN(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 1 : 0)
#define KEYUP(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 0 : 1)

That is the exact code for if a key is up or down... Don''t thank me, thank "The man," Andre LaMothe.

I tried that and I don''t think it worked. This is a console app, I know that works for non-console apps, but I don''t think it was working when I tried it in my Win32 console app. Any other suggestions?

I figured it out, but in case someone else wanted the answer, here it is. You use kbhit() to determine if a key has been hit. Then you use getch() to get the char and act on it.

...or you can write your own keyboard handler that will substitute the default in your program, when you press some key processor is interuppted on some irq, then processor multiplies this irq number with 8 and use that new number in special table(IDT), basically you write appropriate function then you substitute original(first save it), with your own,...you can substitute with some special function that will operate with IDT(check your compiler manual or sth)..i think this works just for console app, in true win32 app you cant do that(use DirectInput or GetAsyn...or WM keyboard functions), when you exit your program you then give back the original function that you have saved in the beginning...

have fun

^cyer: You''re talking about DOS programs. I think ziplux is talking about a Win32 Console App, which is a true Win32 App, only it runs in a DOS-like console window.
