Direct Input Visual Studio Directx

PLEASE can anyone help. stuggling for days to control the cube using a keyboard. can anyone put in the code for me (direct input keyboard) would REALLY appreciate some help.

You did it just to joke at us, didn't you?
You, prankster you.

Edit your post and place code tags aroud your code please. Also, please indent your code if you want to have any hopes of anyone taking a look at it.

Nope, wasnt a joke, can only apologise - complete idiot when it comes to this programming, (obviously, otherwise i wouldnt have asked for help!)

Well, I was joking :)

Now... do edit your initial post please and pace code tags around the code

isnt there is the gl thing?

Code:

---

global bool keys[256]
LRESULT WINAPI MsgProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam )
{
    switch( msg )
    {
        case WM_DESTROY:
            Cleanup();
            PostQuitMessage( 0 );
            return 0;
 
//from NeHe:
case WM_KEYDOWN:                                                // Is A Key Being Held Down?
                {
                        keys[wParam] = TRUE;                                       
// If So, Mark ItAs TRUE
                        return 0;                                                // Jump Back
                }

    }

    return DefWindowProc( hWnd, msg, wParam, lParam );
}
//will check press on space..
if(keys[VK_SPACE]){
 
}

i guess that should work but you will need to include gl files (not sure) also check out :
http://nehe.gamedev.net/data/lessons....asp?lesson=01

He already has a message handler. And no, it isn't OpenGL - its Win32.

bool voo = TRUE; // so fugly...

This would've been better suited for the game programming board. Anyways, I wrote a class to use some basic direct input, and this is just about all it is:

Code:

---

//variables
  LPDIRECTINPUT lpdi;
  LPDIRECTINPUTDEVICE keyboard; 
  unsigned char keystate[256];

//initialization

  if(FAILED(DirectInput8Create(hInst,DIRECTINPUT_VERSION,IID_IUnknown,(void**) &lpdi,NULL)))
  //error
  if (FAILED(lpdi->CreateDevice(GUID_SysKeyboard, &m_keyboard, NULL)))
  //error

  if (FAILED(keyboard->SetDataFormat(&c_dfDIKeyboard)))
  //error

  if (FAILED(keyboard->SetCooperativeLevel(hwnd, DISCL_BACKGROUND | DISCL_NONEXCLUSIVE)))
  //error
  if (FAILED(keyboard->Acquire()))
  //error

  //update input
  if (FAILED(keyboard->GetDeviceState(sizeof(keystate), (LPVOID)keystate)))
    //error

//checking for keydown
  return (keystate[key] & 0x80) ? true:false;

//cleanup
    if (keyboard)
  {
    keyboard->Unacquire();
    keyboard->Release();
    keyboard = 0;
  }
  if (lpdi)
  {
    lpdi->Release();
    lpdi = 0;
  }

Have you looked at a tutorial like two kings? If you want more help, please post specific questions about your problem.
