How can i detect a key stroke that isn''t a regular character, something like the arrow keys? also, how do I detect key strokes without the user haveing to hit enter? I''m using C in Borland C++ 4.52. If you have an answer that uses C++, I can easily switch to C++ instead of C. I have a cannon, and it launches potatoes.

If you''re programming for Win32, you could try virtual keys (WM_KEYDOWN message, with keys: VK_LEFT, VK_RIGHT, ...), or you could add an accelerator resource, and catch the WM_COMMAND...

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

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

if (KEYDOWN(VK_RIGHT))
    {
     //CODE

    }
else if (KEYDOWN(VK_LEFT))
    {
     //CODE

    }
............

You get the idea

okay...yes I am doing for win32. Umm... I''m fairly new at this, so you''ll have to be brutally obvious. I''ll see if I can get it to work. Are there any files I have to include?

Hmmmm....
I can''t remember at the moment. I''m new to C++ myself. I''m at
work right now. When I get home (8 hours from now) I''ll look
and see. But untill then. try winuser.h and make sure user32.lib
is included also. Like I said I''m new too. So if this doesn''t
work I appologize. Good Luck.
Where to use the code is up to you.
