    Thumbs down Needing help with Open GL tutorials

    Hello to all, im stuck at Open GL tutorials by RoD. The thing is that there are several example codes, but i cant compile/build them. only one that compiles is the first ''hello world'' example. others give errors from not finding stdafix.h and errors from something using NULL non-pointers converting and such. i suppose the codes should be all rigth and i thought i would check out what theyd do and figure how they work but now i cant : ( hope that someone can help me with this matter.



    Links to the codes i tried to compile:
    A First Windows Application - Cprogramming.com
    Your First OpenGL Program - OpenGL Tutorials - Cprogramming.com



    and errors that the first link gave "First Windows Application":

    \Ohjelmat\C++\Kehittyneet harjoitukset\WinApp.cpp D:\Ohjelmat\C++\Kehittyneet harjoitukset\D stdafx.h: No such file or directory.

    D:\Ohjelmat\C++\Kehittyneet harjoitukset\WinApp.cpp In function `int WinMain(HINSTANCE__*, HINSTANCE__*, CHAR*, int)':

    82 D:\Ohjelmat\C++\Kehittyneet harjoitukset\WinApp.cpp [Warning] passing NULL used for non-pointer converting 1 of `HWND__* CreateWindowExA(DWORD, const CHAR*, const CHAR*, DWORD, int, int, int, int, HWND__*, HMENU__*, HINSTANCE__*, void*)'

    90 D:\Ohjelmat\C++\Kehittyneet harjoitukset\WinApp.cpp [Warning] passing NULL used for non-pointer converting 3 of `BOOL PeekMessageA(tagMSG*, HWND__*, UINT, UINT, UINT)'

    90 D:\Ohjelmat\C++\Kehittyneet harjoitukset\WinApp.cpp [Warning] passing NULL used for non-pointer converting 4 of `BOOL PeekMessageA(tagMSG*, HWND__*, UINT, UINT, UINT)'


    And btw, these errors were given by dev-c++ compiler, ive tried visual studios c++ to build this and Code::blocks too, nothing qualifies the code, so what am i missing?

    I got it up and running now.. dont know what helped but the point is that it works ^^ still there is one problem though, with the stdafx.h, i cant put it in my code, for some reason it doesnt work in visual studios 2010 even that is supposed to be its own personal thing. but nevertheles, its only supposed to speed up the compiling so i guess it doesnt matter.
