您可以使用VBA返回磁盘的卷GUID吗？

Question

我遇到另一个帖子VBA Open a USB device using it's unique id in wmi 这是没有答案的海报显示了一种方式来通过VBA和WMI获取USB设备的UID，但我不知道如何使用VBA将VolumeGUID从WMI中抽出。

我想获取DeviceID，如果可能的话为特定设备返回VolumeGUID，如果它与DeviceID匹配的话。

这篇文章How to get the volume GUID似乎表明它是可能的，但它是C++

上午我刚刚查询了错误的WMI类？

我曾经有VBS这样做，你可以减少和修改它在VBA中使用。

strComputer = "." 
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2") 

Volume 
MountPoint 


Sub Volume() 
    Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Volume") ' Windows XP and earlier: not available. 
    wscript.echo "[ Win32_Volume ] - " & colItems.Count & " items" 
    For Each objItem in colItems 
     ShowT "Access", objItem.Access 
     ShowT "Automount", objItem.Automount 
     ShowT "Availability", objItem.Availability 
     ShowT "BlockSize", objItem.BlockSize

     wscript.echo "-----" 
    Next 
    wscript.echo vbCrlf & "====================" & vbCrlf 
End Sub 

Sub MountPoint() 
    Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_MountPoint") 
    wscript.echo "[ Win32_MountPoint ] - " & colItems.Count & " items" 
    For Each objItem in colItems 
     ShowT "Directory", objItem.Directory 
     ShowT "Volume", objItem.Volume 
     wscript.echo "-----" 
    Next 
    wscript.echo vbCrlf & "====================" & vbCrlf 
End Sub 

Sub ShowT(s, obj) 
    If Len(obj) > 0 Then Wscript.Echo vbTab & s & ": " & obj 
End Sub
