Problems Displaying Bitmap

[egg management fee]

I'm trying to follow a book to start doing some basic Windows programming and it's going poorly. The book gives examples of several ways to display a bitmap but not all of them are working for me. All of these display correctly except for the first three. Any advise would be very helpful. If you need any more info let me know. Thanks in advance.

Here is the code:

  void GameStart(HWND hWindow)
{
  // Create and load the slide bitmaps
  HDC hDC = GetDC(hWindow);
  g_pSlides[0] = new Bitmap(hDC, TEXT("Image1.bmp"));
  g_pSlides[1] = new Bitmap(hDC, TEXT("Image2.bmp"));
  g_pSlides[2] = new Bitmap(hDC, TEXT("Image3.bmp"));
  g_pSlides[3] = new Bitmap(hDC, IDB_IMAGE4, g_hInstance);
  g_pSlides[4] = new Bitmap(hDC, IDB_IMAGE5, g_hInstance);
  g_pSlides[5] = new Bitmap(hDC, 640, 480, RGB(0, 0, 0));

  // Set the first slide
  g_iCurSlide = 0;
}

Here's the bitmap object file:

Bitmap::Bitmap(HDC hDC, LPCTSTR szFileName)
  : m_hBitmap(NULL), m_iWidth(0), m_iHeight(0)
{
  Create(hDC, szFileName);
}

// Create a bitmap from a resource
Bitmap::Bitmap(HDC hDC, UINT uiResID, HINSTANCE hInstance)
  : m_hBitmap(NULL), m_iWidth(0), m_iHeight(0)
{
  Create(hDC, uiResID, hInstance);
}

// Create a blank bitmap from scratch
Bitmap::Bitmap(HDC hDC, int iWidth, int iHeight, COLORREF crColor)
  : m_hBitmap(NULL), m_iWidth(0), m_iHeight(0)

    // Restore and delete the memory device context
    SelectObject(hMemDC, hOldBitmap);
    DeleteDC(hMemDC);
  }
}

This is the Bitmap Class:

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

  // Helper Methods
  void Free();

public:
  // Constructor(s)/Destructor
  Bitmap();
  Bitmap(HDC hDC, LPCTSTR 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, LPCTSTR 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; };
};

Any ideas? Should I just get a different book?

Okay. I figured it out. The bitmap files for the first three weren't being pulled from the resource file. I had to move the files to the project folder. Still a lot to learn :)
