OpenGL Problems(again)

Nobody on Nehe's forums couldn't help me. I've been programming this little cube with a bitmap texture as a win32 resource in msvc++ 6. My problem is, I can't get the transparency to work. Heres my LoadGLTextures:

Code:

int LoadGLTextures()									// Load Bitmaps And Convert To Textures
{
	
HWND hwnd;
	int Status=TRUE;									// Status Indicator

   // load bitmap from resource file
   HBITMAP bitmap  = LoadBitmap(GetModuleHandle(NULL), 
      MAKEINTRESOURCE(IDB_BITMAP2));


   // setup 24 bits bitmap structure
   // works on 8 bits bitmaps also!


   BITMAPINFO info;
   BITMAPINFOHEADER header;
   header.biSize = sizeof(BITMAPINFOHEADER);     
   header.biWidth = 256;     
   header.biHeight = 256; 
   header.biPlanes = 1;     
   header.biBitCount = 24;     
   header.biCompression = BI_RGB;
   header.biSizeImage = 0;     
   header.biClrUsed = 0;     
   header.biClrImportant = 0; 

   info.bmiHeader = header;
   info.bmiColors->rgbRed      = NULL;
   info.bmiColors->rgbGreen    = NULL;
   info.bmiColors->rgbBlue     = NULL;
   info.bmiColors->rgbReserved = NULL;


   // store bitmap data in a vector
   const int size = 256*256*3;
   unsigned char data[size];  

   HDC hdc = GetDC(hWnd);
      GetDIBits(hdc, bitmap,  0, 256,  &data,  &info, DIB_RGB_COLORS);
  
	  ReleaseDC(hWnd, hdc);
  


   // convert from BGR to RGB
   unsigned char buff;
   for(int i=0; i<256*256; i++)
   {
      buff = data[i*3];
      if(i>=3)
      {
         data[i*3]   = data[i*3+2];
         data[i*3+2] = buff;
      }
   }
 unsigned char  *src_bitmap = data;
   unsigned char *alpha_bitmap = (unsigned char *)malloc(((256)*(256)) *4) ;
   for (unsigned int src = 0, dst = 0; src < (256)*3; src +=3, dst +=4)
{
// if the pixel is black, set the alpha to 0. Otherwise, set it to 255.
	
	if( src_bitmap[src] == 0xFF && src_bitmap[src+1] == 0 && src_bitmap[src+2] == 0xFF )
{
alpha_bitmap[dst+3] = 0;
PostQuitMessage(0); //I tell it to quit, and it WONT!
}
else
alpha_bitmap[dst+3] = 0xFF;

// copy pixel data over
alpha_bitmap[dst] = src_bitmap[src];
alpha_bitmap[dst+1] = src_bitmap[src+1];
alpha_bitmap[dst+2] = src_bitmap[src+2];
}

   // create one texture
   glGenTextures(1, &m_texture[0]);
				
   // select texture
   glBindTexture(GL_TEXTURE_2D, m_texture[0]);

	
   // SetTextureParameters
		glTexImage2D(GL_TEXTURE_2D, 0, 3, 256, 256, 0, GL_RGB, GL_UNSIGNED_BYTE, &data);
		glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
		glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
		glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER, GL_LINEAR_MIPMAP_NEAREST);

   gluBuild2DMipmaps(GL_TEXTURE_2D, 4, 256, 256,
GL_RGBA, GL_UNSIGNED_BYTE, alpha_bitmap);
		// generate texture
   glTexImage2D(GL_TEXTURE_2D, 0, 3, 256, 256, 0, GL_RGB, GL_UNSIGNED_BYTE, &data);
//free all the stuff, etc.

and within my DrawScene(), i have:

Code:

  
glEnable(GL_ALPHA_TEST);
glAlphaFunc(GL_GREATER,0);

right before i draw my cube. My cube's texture has a large pink(255,0,255) square on it that should go transparent, but it doesn't. Help me, please.
Thank you all!

Have you enabled blending (GL_BLEND) ?

yes, under my drawscene().
