problem getting output on display window

I have been working so hard on this but cannot get it to work and cannot see why. I have had to use some replacement code for glaux to load in the teture. I am trying to do a skymap but when i run it, the screen is just black. These are some of my classes

skybox.h

 
#define MAX_TEXTURES 24

class skybox {
public:  //just make everything public than you don't have to worry about access

	skybox() { } //constructor

	bool LoadTexture(unsigned int & aTexture, const char * bitmap_file);
	void Init();
	void draw();


	GLuint texture[MAX_TEXTURES];

	//used to correct the edges of the skybox overlap
	//try setting this to 0.0 in the Init() and you will see the seams of the textures
	double	OFFSET,	rot_x, rot_y;
	long	text_offset;
};

skybox.cpp

 
#include "stdafx.h"
#include <GL/glut.h>
#include <windows.h>
#include <stdio.h>  //for file access							
#include <gl\gl.h>													
#include "skybox.h"
#include "glbmp.h"


bool skybox::LoadTexture(unsigned int & aTexture, const char * bitmap_file)
{
   glbmp_t bitmap;     //object to fill with data from glbmp
 

   if(!glbmp_LoadBitmap(bitmap_file, 0, &bitmap))
   {
      fprintf(stderr, "Error loading bitmap file: %s
", bitmap_file);
   }
 
   //generate and bind the OpenGL texture
   glGenTextures(1, &aTexture);
   glBindTexture(GL_TEXTURE_2D, aTexture);
 
   //copy data from bitmap into texture
   glTexImage2D(GL_TEXTURE_2D, 0, 3, bitmap.width, bitmap.height,
                0, GL_RGB, GL_UNSIGNED_BYTE, bitmap.rgb_data);
 
   //set up texture filtering
   glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
   glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
 
   //free the bitmap
   glbmp_FreeBitmap(&bitmap);
 
   return true;
}
 


void skybox::Init() {

	OFFSET = 1/512.0; //set offset value for skybox

	rot_x = 0.0; rot_y = 0.0;

Anyhelp in helping me sort this out would be so greatful
cheers

At least add glutReshapeFunc(ReSizeGLScene); in your main. After I was able to see your skybox with texture disabled.

hmm, interesting, without it the screen is black, with it the screen is white. I dont know if that means anything. I dont know if my LoadTexture method is doing what its supposed too.

Did you forget to call InitGL function just before glutMainLoop ?

wow, all this time stressing just because i forgot to add my functions in my main. I got confused because i thought that the aSkyBox.Init(); was doing this for me.
Thanks very much for your help, dearly appreciated.
