i need a simple implementation for this Bitmap CLASS

{
protected:
// Member Variables
HBITMAP m_hBitmap;
int m_iWidth, m_iHeight;

// Helper Methods
void Free();

public:
// Constructor(s)/Destructor
Bitmap();
Bitmap(HDC hDC, LPTSTR szFileName);
Bitmap(HDC hDC, UINT uiResID, HINSTANCE hInstance);
Bitmap(HDC hDC, int iWidth, int iHeight,
COLORREF crColor = RGB(0, 0, 0));
virtual ~Bitmap();

// General Methods
BOOL Create(HDC hDC, LPTSTR szFileName);
BOOL Create(HDC hDC, UINT uiResID, HINSTANCE hInstance);
BOOL Create(HDC hDC, int iWidth, int iHeight, COLORREF crColor);

void Draw(HDC hDC, int x, int y);
int GetWidth() { return m_iWidth; };
int GetHeight() { return m_iHeight; };
};

class Bitmap
