Win2000下怎么修改屏幕分辨率和颜色？

用ChangeDisplaySettingsEx（）在win2000下怎么不行？
谢谢指教！

int nFullWidth=GetSystemMetrics(SM_CXSCREEN);
int nFullHeight=GetSystemMetrics(SM_CYSCREEN);
bool bChanged=0;
if(nFullWidth!=800 ¦¦ nFullHeight!=600)//change from && to ¦¦
{
DEVMODE lpDevMode;
lpDevMode.dmBitsPerPel=16;//Change from 24 to 16
lpDevMode.dmPelsWidth=800;
lpDevMode.dmPelsHeight=600;
lpDevMode.dmDisplayFrequency=85;
lpDevMode.dmSize=sizeof(DEVMODE);
lpDevMode.dmFields =DM_PELSWIDTH¦DM_PELSHEIGHT¦DM_BITSPERPEL¦DM_DISPLAYFREQUENCY;
LONG result;
//EnumDisplaySettings(NULL,ENUM_REGISTRY_SETTINGS,&lpDevMode);
result=ChangeDisplaySettingsEx(NULL,&lpDevMode,NULL,0,NULL);
if (result==DISP_CHANGE_SUCCESSFUL)
{
result=ChangeDisplaySettingsEx(NULL,&lpDevMode,NULL,CDS_UPDATEREGISTRY,NULL);

bChanged=1;
}
else
{
result=ChangeDisplaySettingsEx(NULL,&lpDevMode,NULL,0,NULL);
}
}
可能你的显示器不支持那种显示模式
