Here I have part of an OPENGL program that ultimately shows a triangle rotating...that isn't important. What is important is the three errors I get in the block of following code...btw, it is for creating a fullscreen window:
If you know any opengl the code should be easy to understand...my three errors are:
//fullscreen stuff needs to be done before the window is created otherwise weird things can happen!!!!
memset(&devModeScreen, 0, sizeof(devModeScreen));
devModeScreen.dmSize = sizeof(devModeScreen);
devModeScreen.dmPelsWidth = 1024; //You are supposed to use the same width and height in the DEVMODE
devModeScreen.dmPelsHeight = 768; //datastructure as when you actually create the window
devModeScreen.dmBitsPerPel = 16; //This should probably be the same...currently my system is running in 16bbp
//so it seemed like a good idea to use 16
devModeScreen.dmFields = DM_PELSWIDTH | DM_PELSHEIGHT | DM_BITSPERPEL;
if(ChangeDisplaySettings(&devModeScreen, CDS_FULLSCREEN) != DISP_CHANGE_SUCCESSFUL)
fullScreen = false;
extendedWindowStyle = WS_EX_APPWINDOW;
windowStyle = WS_POPUP;
extendedWindowStyle = NULL;
windowStyle = WS_OVERLAPPEDWINDOW | WS_VISIBLE | WS_SYSMENU | WS_CLIPCHILDREN | WS_CLIPSIBLINGS;
hwnd = CreateWindowEx(NULL, //window creation
"The OPENGL windows application",
WS_OVERLAPPEDWINDOW | WS_VISIBLE |
WS_SYSMENU | WS_CLIPCHILDREN |
--------------------Configuration: opengl - Win32 Debug--------------------

Error executing cl.exe.

well what do you know, only two errors, hot dog!
Thanks if you can explain what I did wrong.
