Why doesn't glbindtexture recognize the texture id I pass it?

Down below in the code snippet you will see that I load a texture, then bind the ID.

I will complete this operation multiple times before finally using the actual id to texture map my cube.
Currently I'm completing these operations in the global scope like so:

Code:

---

        typedef ResourceManager<ResourceTexture> TexManager;
    TexManager Manager;   
        TexManager::Handle hTex0 = Manager.LoadResource( "axe.bmp" );
    TexManager::Handle hTex1 = Manager.LoadResource( "grass.bmp" );
    TexManager::Handle hTex0Again = Manager.LoadResource( "axe.bmp" );   
        const ResourceTexture &Tex0 = Manager.GetResource( hTex0 );
    const ResourceTexture &Tex1 = Manager.GetResource( hTex1 );
    const ResourceTexture &Tex0Again = Manager.GetResource( hTex0Again );

---

I have stepped through the process multiple times, I can confirm that each handle has a unique texture ID created by the function below, with glBindTexture.

Now I try to texture map:

glBindTexture(GL_TEXTURE_2D, Tex0.GetID());

When the program runs, I get no errors, and I would if something was amiss with the code I have.
The cube I have drawn on the screen that the function glBindTexture applies to comes up solid white, no texturing.


I was reading documentation on glBindTexture, and I found this snippet:

"Texture names are unsigned integers. The value zero is
reserved to represent the default texture for each texture
target. Texture names and the corresponding texture
contents are local to the shared display-list space (see
glXCreateContext) of the current GL rendering context; two
rendering contexts share texture names only if they also
share display lists."

I feel that this might have something to do with the problem, but I am unsure how to resolve it.

Code:

---

bool       
ResourceTexture::LoadResource( const std::string &filename )
{
    assert( 0 == m_Texture );
        //add texture loading process here.
        Bitmap image;                                                                        // Create Storage Space For The Textures
        image.Load(filename);
 
        // Load The Bitmap, Check For Errors, If Bitmap's Not Found Quit
        if ( image.GetImg() != NULL )                // If Texture Image Exists
        {
                glGenTextures(1, &m_Texture);                                                // Create The Texture
 
                // Typical Texture Generation Using Data From The Bitmap
                glBindTexture(GL_TEXTURE_2D, m_Texture);
                glTexImage2D(GL_TEXTURE_2D, 0, 3, image.GetWidth(), image.GetHeight(), 0, GL_RGB, GL_UNSIGNED_BYTE, image.GetImg());
                glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
                glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
                SetFilename( filename );
                return true;
        }
        else
                return false;     
}

Are you trying to load the textures before OpenGL is initialized?

Oh bob, you know me all too well.

hahahahaha.

Hey look here they are right at the top of the main cpp file!

Code:

---

#include "Camera.h"
#include "Scene_Manager.h"
#include "Math3d.h"
#include "Resource_Manager.h"
#include "RCTexture.h"

#define CDS_FULLSCREEN 4        // Compilers. By Defining It This Way,
#endif                                                // We Can Avoid Errors

GL_Window*        g_window;

bool        keys[256];                        // Array Used For The Keyboard Routine
// User Defined Variables
       
UINT        MouseX, MouseY;                // Coordinates for the mouse
UINT        CenterX, CenterY;        // Coordinates for the center of the screen.

Camera Cam;                                // Our Camera for moving around and setting prespective
                                                        // on things.

void CheckMouse(void);                // Function Prototypes
void CheckKeys(void);

        typedef ResourceManager<ResourceTexture> TexManager;
    TexManager Manager;   
        TexManager::Handle hTex0 = Manager.LoadResource( "axe.bmp" );
    TexManager::Handle hTex1 = Manager.LoadResource( "grass.bmp" );
    TexManager::Handle hTex0Again = Manager.LoadResource( "axe.bmp" );   
        const ResourceTexture &Tex0 = Manager.GetResource( hTex0 );
    const ResourceTexture &Tex1 = Manager.GetResource( hTex1 );
    const ResourceTexture &Tex0Again = Manager.GetResource( hTex0Again );

So I take it that fixed it? I only thought of that because I've done the same thing.

Well, I'm positive that it would fix it.

But I hate to move things into classes until they have a permanent home :\

And I'm not quite sure where to put this bit of functionality yet.
