Most reliable way to handle keyboard input?

I've been using DirectX 7 Direct Input for keyboard polling, but for some reason every once in a while when I run the program the keys are NOT recongnized. I have to re-start VB and then run the app again and all is fine.

I'm considering switching over to GetAsyncKeyState for all of my keyboard handling. I've used this reliably in the past. Is there any benefit to using Direct Input over the GetAsyncKeyState api?

Also, could the GetAsyncKeyState api AND DirectX Input for Joystick reading work at the same time? Thanks...

You could use DirectInput from directX. This is a mediocore to good way of handling keyboard inputs. Takes a lot of work, but is more or less reliable!

http://www.directx4vb.com/ has a tutorial on it

Hey Joon, no prob. The "problem" seems to only happen in the editor, it hasn't happened to any exe I've made. So, perhaps it's not that big of a deal. Plus after a few uh.. "crashes" I have to reboot VB because everything kind of breaks down.

Sounds like you might have a memory leak or something. Are you making sure to set all your objects = Nothing and unload everything when you're done?

Yep. Thanks for asking, as that is a good point. I've been modifying my engine by the hour, the more I update, the better everything is working and the less overall problems. The keyboard problem hasn't happened for quite a while so I'm going to stick with DI for the keyboard.
