python实例31[自动挂载虚拟盘]

 

在windows上使用subst和netuse

(returncode, drive)  =  AutoSubstorNetuse( " C:\\test " )
(returncode, drive)  =  AutoSubstorNetuse( " \\\\remotemachinenameorip\\shared " )

 

 

强制挂载到某个虚拟盘：

 

SubstDriveToPathF()

NetuseDriveToPathF()

 

自动查找没有使用的盘来挂载：

AutoSubstorNetuse()

 

完!
