关闭屏幕保护功能，改变屏保等待_visualbasic教程

　　此外希望只有本次使用Windows时改变(下次开机时还原原状)，则最後参数改为　SPIF_SENDWININICHANGE(没有SPIF_UPDATEINIFILE)

ConstSPI_SETSCREENSAVEACTIVE=17
ConstSPI_SETSCREENSAVETIMEOUT=15
ConstSPIF_SENDWININICHANGE=&H2
ConstSPIF_UPDATEINIFILE=&H1

PrivateDeclareFunctionSystemParametersInfoLib”user32″Alias_
　　”SystemParametersInfoA”(ByValuActionAsLong,ByValuParamAsLong,_
　　ByVallpvParamAsLong,ByValfuWinIniAsLong)AsLong

PrivateSubSetScreenSaveTimeout(ByValBySecondAsLong)
　CallSystemParametersInfo(SPI_SETSCREENSAVETIMEOUT,BySecond,0,_
　　　　　SPIF_UPDATEINIFILE SPIF_SENDWININICHANGE)
EndSub

PrivateSubEnableScreenSave()
　CallSystemParametersInfo(SPI_SETSCREENSAVEACTIVE,1,0,_
　　　　　SPIF_UPDATEINIFILE SPIF_SENDWININICHANGE)
EndSub
PrivateSubDisableScreenSave()
　CallSystemParametersInfo(SPI_SETSCREENSAVEACTIVE,0,0,_
　　　　　SPIF_UPDATEINIFILE SPIF_SENDWININICHANGE)
EndSub->
