c++ - Windows function ChoosePixelFormat returns ERR_OLD_WIN_VERSION on windows 7 -

i'm trying teach myself win32 api making window , attaching opengl context it. in order fetch appropriate pixel format call choosepixelformat must made should return pixel format system supports , best meets needs. when check errors goes smoothly until function called stops execution , logs error 1150-err_old_win_version supposed mean version of windows not support function. not case , msdn confirms function runs on versions of windows since windows 2000. right i'm running windows 7 x64 on desktop , made sure video driver , os updated. lots of people seem have had trouble pixel format functions have not found problem decided post here help. here full code; have not tested on machines other own.

winmain.cpp (the non-default msvc lib linked opengl32.lib)

#include"display.h" #include<iostream> #include<fstream>  msg message; dword error; int status;  lresult callback wndproc(hwnd hwindow, uint message, wparam wparam, lparam lparam) {   switch(message)     {case wm_create:         return 0;     case wm_destroy:         postquitmessage(0);         return 0;     case wm_keydown:         switch(wparam)         {case vk_escape:             postquitmessage(0);             return 0;}}     return defwindowproc(hwindow, message, wparam, lparam);}  int mainloop(display d) {     while((status = peekmessage(&message, d.hwindow, 0, 0, pm_remove)) != 0)     {         if (status == -1)         {             return -1;         }         dispatchmessage(&message);     }     return 0; }  int callback winmain(hinstance hinstance, hinstance hprevinstance, lpstr lpcmdline, int ncmdshow) {     std::ofstream file("log.txt", std::ios::trunc);       display window("test", hinstance, wndproc, 50, 50, 50, 50, null, null);     if(window.status == -1)     {   error = getlasterror();         file << error;         return 1;}      showwindow(window.hwindow, sw_shownormal);     enablewindow(window.hwindow, true);     mainloop(window);      return 0; } 

display.h (problem occurs in class constructor)

#include <windows.h>  class display    {public:     display(const char*, hinstance, wndproc, int, int, int, int, dword, dword);     ~display();     hwnd hwindow;     int status; private:     wndclassex data;     hdc hdevicecontext;     hglrc hglcontext;     pixelformatdescriptor pfd;     int x, y, width, height;}; display::display(const char* title, hinstance instancehandle, wndproc windowprocedure, int screenpositionx, int screenpositiony, int windowwidth, int windowheight, dword styleflags, dword extendedstyleflags) {   data.cbsize = sizeof(wndclassex);     data.style = cs_owndc;     data.lpfnwndproc = windowprocedure;     data.cbclsextra = 0;     data.cbwndextra = 0;     data.hinstance = instancehandle;     data.hicon = null;     data.hcursor = null;     data.hbrbackground = null;     data.lpszmenuname = null;     data.lpszclassname = "win1";      data.hiconsm = null;     registerclassex(&data);     hwindow = createwindowex(extendedstyleflags, data.lpszclassname, title, styleflags | ws_clipsiblings | ws_clipchildren, x = screenpositionx, y = screenpositiony, width = windowwidth, height = windowheight, null, null, instancehandle, null);     pfd.nsize = sizeof(pixelformatdescriptor);     pfd.nversion = 1;     pfd.ipixeltype = pfd_type_rgba;     pfd.ilayertype = pfd_main_plane;     pfd.dwvisiblemask = 0;     pfd.dwlayermask = 0;     pfd.dwdamagemask = 0;     pfd.dwflags = pfd_draw_to_window | pfd_doublebuffer | pfd_support_opengl;     pfd.cauxbuffers = 0;     pfd.breserved = 0;     pfd.ccolorbits = 24;     pfd.caccumbits = 0;     pfd.cdepthbits = 32;     pfd.cstencilbits = 0;     pfd.calphabits = 0;     pfd.caccumalphabits = 0;     pfd.calphashift = 0;     pfd.cbluebits = 0;     pfd.caccumbluebits = 0;     pfd.cblueshift = 0;     pfd.cgreenbits = 0;     pfd.caccumgreenbits = 0;     pfd.cgreenshift = 0;     pfd.credbits = 0;     pfd.caccumredbits = 0;     pfd.credshift = 0;     hdevicecontext = getdc(hwindow);     int pf = choosepixelformat(hdevicecontext, &pfd); //throws error 1150, next 3 throw error 2000 because of failing     setpixelformat(hdevicecontext, pf, &pfd);     hglcontext = wglcreatecontext(hdevicecontext);     wglmakecurrent(hdevicecontext, hglcontext);     if(getlasterror() != error_success)         {status = -1;}     else         {status = 0;}     return;} display::~display() {   wglmakecurrent(null, null);     wgldeletecontext(hglcontext);     destroywindow(hwindow);     unregisterclass(data.lpszclassname, data.hinstance);} 

after have tried mentioned solutions still had same problem err_old_win_version after choosepixelformat. in case problem graphics card driver:

the system i'm working on uses evga card gtx 770 gpu , yesterday installed driver version 331.65. after got same problems questioner. installing current version 337.88 fixed issue in case. err_old_win_version seams lead in wrong direction.
