代码:
FunctionGetSerialNumber(sRootAsString)AsLong DimlSerialNumAsLong DimRAsLong DimsTemp1AsString,sTemp2AsString strLabel=String$(255,Chr$(0)) 注释:磁盘卷标 strType=String$(255,Chr$(0)) 注释:文件系统类型一般为FAT R=GetVolumeInformation(sRoot,strLabel,Len(strLabel),lSerialNum,0,0,strType,Len(strType)) GetSerialNumber=lSerialNum 注释:在strLabel中为磁盘卷标 注释:在strType中为文件系统类型 EndFunction
用法:
当驱动器不存在时,函数返回0。如果是个非根目录,也将返回0:
lSerial=GetSerialNumber("c:\")-> |
