I'm having trouble sending a keyboard event to a particular program. I'd like to send UpArrow, DnArrow, LeftArrow, And RightArrow keypresses to a certain program while it doesn't have focus. I've tried SendMessageByNum using WM_KEYDOWN, VK_RETURN, VK_SPACE, and WM_KEYUP (as you might be able to see, i don't really know what i'm doing, and i just test things out until they work). Next I tried keyboard_event but as far as I can tell, you can't send it to a particular program. Anyone that could help me, it'd be greatly appreciated. Thanks!
