您可以使用 VBA 返回磁盘的卷 GUID 吗？

Question

我遇到了另一个帖子VBA Open a USB device using it's unique id in wmi 海报展示了一种通过 VBA 和 WMI 获取 USB 设备 UID 的方法，但我不确定如何使用 VBA 从 WMI 中检索 VolumeGUID。

如果特定设备与 DeviceID 匹配，我想获取 DeviceID，然后返回 VolumeGUIDs（如果可能）。

这篇帖子How to get the volume GUID 似乎暗示这是可能的，但它是针对 C++ 的

我只是在查询错误的 WMI 类吗？

我以前有VBS来做这个，你可以减少和修改它以在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
        ShowT "Capacity", objItem.Capacity
        ShowT "Caption", objItem.Caption
        ShowT "Compressed", objItem.Compressed
        ShowT "Description", objItem.Description
        ShowT "DeviceID", objItem.DeviceID
        ShowT "DirtyBitSet", objItem.DirtyBitSet
        ShowT "DriveLetter", objItem.DriveLetter
        ShowT "DriveType", objItem.DriveType
        ShowT "FileSystem", objItem.FileSystem
        ShowT "FreeSpace", objItem.FreeSpace
        ShowT "IndexingEnabled", objItem.IndexingEnabled
        ShowT "Label", objItem.Label
        ShowT "MaximumFileNameLength", objItem.MaximumFileNameLength
        ShowT "Name", objItem.Name
        ShowT "NumberOfBlocks", objItem.NumberOfBlocks
        ShowT "PNPDeviceID", objItem.PNPDeviceID
        ShowT "Purpose", objItem.Purpose
        ShowT "Status", objItem.Status
        ShowT "StatusInfo", objItem.StatusInfo
        ShowT "SerialNumber", objItem.SerialNumber
        ShowT "SupportsDiskQuotas", objItem.SupportsDiskQuotas
        ShowT "SupportsFileBasedCompression", objItem.SupportsFileBasedCompression
        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
