我遇到了另一篇帖子VBA Open a USB device using it's unique id in wmi 海报展示了通过VBA和WMI获取USB设备UID的方法,但我不知道如何用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VolumeGUID(如果可能)。
这篇文章How to get the volume GUID似乎表明它是可能的,但它适用于C ++
我只是查询错误的WMI类吗?
答案 0 :(得分:3)
我曾经让VBS这样做,你可以减少和修改它以便在VBA中使用。
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")

Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Volume") ' Windows XP and earlier: not available.
wscript.echo "[ Win32_Volume ] - " & colItems.Count & " items"
