Im trying to use direct input. However everytime i try to i get the following error message. Error Message: The procedure entry point c_dfDIKeyboard could not be located in the dynamic link library dinput.dll I have no idea what this means and the SDK provides no help. Does anybody have an idea of whats going wrong. By the way im using Dev C++. Here is my code:


#define WIN32_LEAN_AND_MEAN

#include <dinput.h>
#include <d3dx9.h>
#include <windows.h>


// Globals

LPDIRECTINPUT lpdi;
LPDIRECTINPUTDEVICE m_keyboard;
HWND hWND;
HINSTANCE g_hinstance;
bool done = false;


unsigned char keystate[256];

void Init(void)
{
  if (FAILED(DirectInput8Create(GetModuleHandle(NULL), DIRECTINPUT_VERSION, 
    IID_IDirectInput8, (void**)&lpdi, NULL)))
  {
    // error code

  }
  
  if (FAILED(lpdi->CreateDevice(GUID_SysKeyboard, &m_keyboard, NULL)))
    { /* error code */ }
  
  if (FAILED(m_keyboard->SetDataFormat(&c_dfDIKeyboard)))
    { /* error code */ }
  
  if (FAILED(m_keyboard->SetCooperativeLevel(hWND, DISCL_BACKGROUND |
    DISCL_NONEXCLUSIVE)))
    { /* error code */ }
  
  if (FAILED(m_keyboard->Acquire()))
    { /* error code */ }
}

void CleanUp()
{
  if (m_keyboard)
    m_keyboard->Release();
  
  if (lpdi)
    lpdi->Release();
}


void Render() {

}

void GameLoop()
{
    //Enter the game loop

    MSG msg; 
    BOOL fMessage;

    PeekMessage(&msg, NULL, 0U, 0U, PM_NOREMOVE);
    
    while(msg.message != WM_QUIT)
    {
        fMessage = PeekMessage(&msg, NULL, 0U, 0U, PM_REMOVE);

        if(fMessage)
        {
            //Process message

            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }
        else
        {
            //No message to process, so render the current scene

            Render();
        }

    }

                break;

Link your program with Dxguid.lib OR #define INITGUID before the #include''s

i linked it with dxguid and it still doesnt work. Could it be because im using the Dev C++ package for direct x?
does no one know how?
If my directx isn't to rusty I think you have to link also with dinput.lib too
