DirectX9 _GUID unresolved external - compile time error.

I am getting an unresolved external for the following:
c_dfDIKeyboard
GUID_SysKeyboard
DirectInput8Create@20
IID_IDirectInput8A


It seems that it would be due to me not linking things properly...

But my linker has additional libraries under:
C:/Program Files/Microsoft DirectX SDK (August 2007)/Lib/x86

And additional includes under:
C:/Program Files/Microsoft DirectX SDK (August 2007)/Includes


....and both of those directories are correct for me.


So here is a huge chunk of code.

Code:

#ifndef _INPUT_H_
#define _INPUT_H_

#include "d3d9.h"
#include "d3dx9.h"
#include <dinput.h>
#pragma comment(lib, "d3dx9.lib")
#pragma comment(lib, "d3d9.lib")
class InputDevice
{
public:
	~InputDevice(void);
	LPDIRECTINPUT8 Interface;
	LPDIRECTINPUTDEVICE8 Device;
protected:
	InputDevice(void);
private:
};

#endif

Code:

#ifndef _KEYBOARD_H_
#define _KEYBOARD_H_
#include "inputdevice.h"
#include <iostream>
#include "keys.h"
using namespace std;
class KeyboardDevice : public InputDevice
{
public:
	KeyboardDevice(void){}
	KeyboardDevice(HWND hWnd, HINSTANCE hInstance);
	~KeyboardDevice(void);
	void Update(void);
	bool Pressed(Key key);
	void Print(void);
//protected:
	unsigned char state[256], pState[256];
};
#endif

Code:

#include "window.h"
#include "point.h"
#include "graphicdevice.h"
#include "application.h"
#include <windows.h>
#include "keyboarddevice.h"
//#define KEY_DOWN(vk_code) (GetAsyncKeyState(vk_code) & 0x8000 ? 1 : 0)
//#define KEY_UP(vk_code) (GetAsyncKeyState(vk_code) & 0x8000 ? 0 : 1)

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{

	Window AppWindow(hInstance, nShowCmd, Point(500, 500), Point(50, 50), FALSE);
	GraphicDevice Graphics(AppWindow.Handle());
	Application Program = Application();
	KeyboardDevice Keyboard(AppWindow.Handle(), hInstance);
	MSG WindowsMessages;

	Program.LoadContent();
	while(1)
	{
		if(Keyboard.Pressed(Keys::Escape)) PostMessage(AppWindow.Handle(), WM_DESTROY, 0, 0);
		while(PeekMessage(&WindowsMessages, NULL, 0, 0, PM_REMOVE))
		{
			TranslateMessage(&WindowsMessages);
			DispatchMessage(&WindowsMessages);
		} if(WindowsMessages.message == WM_QUIT) break;

		Keyboard.Update();
		Program.DrawStart(Graphics);
		Program.Draw();
		Program.DrawEnd(Graphics);
	}
	Program.UnloadContent();
	//Graphics.Dispose();
	return WindowsMessages.wParam;
}

...If you need more code than this, let me know and I will post it.

You must link with dxguid.lib, dinput8.lib and dinput.lib
