    loading pics

    whats wierd though is that im doing an online tutorial and if i use the pic it uses my program works but if i try to load a pic even with the same name it doesnt. it all compiles fine but i get an error after prompting for fullscreen saying "initialization failed" and it closes out. heres my code: #include <stdlib.h> #include <windows.h> // Header File For Windows #include <stdio.h> // Header File For Standard Input/Output #include <gl\gl.h> // Header File For The OpenGL32 Library #include <gl\glu.h> // Header File For The GLu32 Library #include <glaux.h> // Header File For The Glaux Library HDC hDC=NULL; // Private GDI Device Context HGLRC hRC=NULL; // Permanent Rendering Context HWND hWnd=NULL; // Holds Our Window Handle HINSTANCE hInstance; // Holds The Instance Of The Application bool keys[256]; // Array Used For The Keyboard Routine bool active=TRUE; // Window Active Flag Set To TRUE By Default bool fullscreen=TRUE; // Fullscreen Flag Set To Fullscreen Mode By Default bool light; // Lighting ON/OFF ( NEW ) bool lp; // L Pressed?

    Way to include all preprocessors

    i meant compile slow and how do u precompile it? do you just compile the header after you make it and then the program you use doesnt have to compile it?

    Way to include all preprocessors

    Quote:Original post by doynax I guess you could create a header of your own and add any new ones to it as needed. It won't be good for you compilation times though (unless you precompile it).. Still, it's probably a good idea to learn roughly where everything belongs. It's generally quite easy to look it up if you're unsure. I noticed wat u mean by it being slow. is there a way to make it run faster?

    Way to include all preprocessors

    wat do u mean by sorta?
