FullScreen ?

i am making a opengl program and was wondering how would i make it full screen. When i put this code in the compiler says its wrong:

Code:

---

DEVMODE devModeScreen;
memset(&devModeScreen,0,sizeof(devModeScreen));
devModeScreen.dmSize = sizeof(devModeScreen);
devModeScreen.dmPelsWidth = screenWidth;
devModeScreen.dmpelsHeight = screenHeight;
devModeScreen.dmBitsPerPel = screenBpp;
devModeScreen.dmFields = DM_PELSWIDTH | DM_PELSHEIGHT | DM_BITSPERPEL;

if (ChangeDisplaySettings(&devModeScreen, CDS_FULLSCREEN) != DISP_CHANGE_SUCCESSFUL)
fullscreen = false;

---

I've never written any OpenGL code before but I did notice an inconsistency on yoru code:

Code:

---

devModeScreen.dmpelsHeight = screenHeight;

---

probably ought to be:

Code:

---

devModeScreen.dmPelsHeight = screenHeight;

---

Just as a quick request, next time you have a problem with compilation if you could post the compiler errors as well it makes it a bit easier since most of the time it's something obvious.
