I am trying to get the keyboard to work. I have this code,


public void InitKeyboard()
{
	keyb = new Microsoft.DirectX.DirectInput.Device(SystemGuid.Keyboard);
	keyb.SetCooperativeLevel(this, CooperativeLevelFlags.Background | CooperativeLevelFlags.NonExclusive);
	keyb.Acquire();
}

but when it gets ran it gives me this error, right around the Acquire part. Do i have to reinstall directx, or do I have a different version. That code should work shouldn't it?


"An unhandled exception of type 'Microsoft.DirectX.DirectInput.UnsupportedException' occurred in microsoft.directx.directinput.dll"

Unsupported Exception means that you've requested a behavior that is not supported. You aren't allowed to get background access to the keyboard. You should specify CooperativeLevelFlags.Foreground instead of CooperativeLevelFlags.Background.

Now I get this error. It is the only program running too.

"Microsoft.DirectX.DirectInput.OtherApplicationHasPriorityException"

You should wait to acquire the device until after the application has been activated (usually by a Form.Show() call). If you are doing the acquire before the form is up, the acquire will fail.
