是否可以在DirectDraw的全屏幕独占模式下用OpenGL绘图？？？？？

[hexenzhou]

DirectX下可以实现全屏幕独占模式，我想实现在这种模式用OpenGL绘图，不知是否可行，怎样实现？？？我感觉这种模式比窗口方式要快。我不会使用Direct3D。

OpenGL自己就可以实现全屏幕独占绘图，为什么要用DIRECTX呢？

不可以

在hWnd=CreateWindowEx（）函数前

wc.hCursor = LoadCursor(NULL, IDC_ARROW); wc.hbrBackground = NULL; wc.lpszMenuName = NULL; wc.lpszClassName = "OpenGL";
RegisterClass(&wc);
DEVMODE dmScreenSettings; memset(&dmScreenSettings,0,sizeof(dmScreenSettings)); dmScreenSettings.dmSize=sizeof(dmScreenSettings); dmScreenSettings.dmPelsWidth = width; dmScreenSettings.dmPelsHeight = height; dmScreenSettings.dmBitsPerPel = bits; dmScreenSettings.dmFields=DM_BITSPERPEL|DM_PELSWIDTH|DM_PELSHEIGHT;
if (ChangeDisplaySettings(&dmScreenSettings,CDS_FULLSCREEN) != ISP_CHANGE_SUCCESSFUL)
{
return;
}
dwExStyle=WS_EX_APPWINDOW; dwStyle=WS_POPUP; ShowCursor(FALSE);
AdjustWindowRectEx(&WindowRect, dwStyle, FALSE, dwExStyle);
