Unresolved External

[ElWhapo]

If you read my post "Tga" earlier about the image library i am creating that relates to this post as well. This time I am having a problem somewhere that I can't find. The two errors I get are both Unresolved External errors for the function DBIL_Initialize() and the function DBIL_DeInitialize() because those are the only two I'm calling from the DLL. Here is my code, please help.

"Main.h" (Where I import from DLL)

#include <windows.h>
#include <ddraw.h>

#define DLLEXP __declspec(dllexport)

#pragma comment(lib,"ddraw.lib")
#pragma comment(lib,"dxguid.lib")

#define g_szClassName "CLASS!"

// Image Types For DBIL_LoadImage() Function
#define BITMAP_IMAGE_FILE 0x00AA
#define TARGA_IMAGE_FILE 0x00BB

// Methods Of Display For DBIL_DisplayImage() Function
#define NORMAL_IMAGE 0x00AAAA
#define TRANSPARENT_IMAGE 0x00AABB
#define BACKGROUND_IMAGE 0x00AACC
#define PORTION_IMAGE 0x00AADD

enum
{
	ePrimary,
	eBack,
	eMaxSurfaces,
};

typedef struct
{
    BYTE IDLength;
    BYTE ColorMapType;
    BYTE ImageType;
    WORD CMapStart;
    WORD CMapLength;
    BYTE CMapDepth;
    WORD XOffset;
    WORD YOffset;
    WORD Width;
    WORD Height;
    BYTE PixelDepth;
    BYTE ImageDescriptor;
} TGA_Header;

typedef struct
{
    HWND hWnd;
    RECT Rect;
    HANDLE Compatible;
    HANDLE Old;
    HDC Front;
    HDC Back;
    HDC Bitmap;
} BUFFER;

typedef struct
{
	LPDIRECTDRAW2 Interface;
	LPDIRECTDRAWSURFACE Surfaces[eMaxSurfaces];
	LPDIRECTDRAWCLIPPER Clipper;
} TRANS_IMAGE;

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

DLLEXP HBITMAP DBIL_LoadImage(HINSTANCE, LPSTR, UINT, UINT);
DLLEXP bool DBIL_Initialize(BUFFER, TRANS_IMAGE, HWND);
DLLEXP bool DBIL_DisplayImage(BUFFER, HBITMAP, UINT, INT, INT, RECT, TRANS_IMAGE);
DLLEXP bool DBIL_DeInitialize(BUFFER, TRANS_IMAGE);
DLLEXP bool DBIL_ClearScreen(HDC, RECT, INT);

"Main.cpp" (I'm just posting where I have the problem)

#include "Main.h"
...........................

case WM_CREATE:
	DBIL_Initialize(pBuffer, pTrans, hWnd);
	break;

...........................

case WM_DESTROY:
	DBIL_DeInitialize(pBuffer, pTrans);
        PostQuitMessage(0);
	break;

You need to link to the DLL in order to call its functions, or use LoadLibrary() and GetProcAddress().
