Problem with Managed DirectInput

[dxfoo]

I press down 'S' on the keyboard, and the character still sits at the same previous position. Why is this?

You might want to see this thread http://www.xtremedotnettalk.com/showthread.php?t=93639. I know that code works because I am using it in a project I'm working on. It gets the input in a different way. I don't know which is more effecient, but that example works.

Thanks for the input; however, I dramatically changed my code after learning how to apply 3d to 2d. For the input, I was able to do this...

 

       // Call this before showing form. 
       public void InitializeInput()
       {
           // Create our keyboard device
           deviceInput = new Microsoft.DirectX.DirectInput.Device(SystemGuid.Keyboard);
           deviceInput.SetCooperativeLevel(this, CooperativeLevelFlags.Background | CooperativeLevelFlags.NonExclusive);
           deviceInput.Acquire(); 
       }

       // Game loop method
       private void UpdateInputState()
       {
           KeyboardState state = deviceInput.GetCurrentKeyboardState();

           if (state[Key.Escape])
               this.Close();
           if (state[Key.S])
               PC.Y += 10;
           if (state[Key.W])
               PC.Y -= 10;
           if (state[Key.A])
               PC.X -= 10;
           if (state[Key.D])
               PC.X += 10; 
       }
