您可以使用VBA返回磁盤的卷GUID嗎？

Question

我遇到另一個帖子VBA Open a USB device using it's unique id in wmi 這是沒有答案的海報顯示了一種方式來通過VBA和WMI獲取USB設備的UID，但我不知道如何使用VBA將VolumeGUID從WMI中抽出。

我想獲取DeviceID，如果可能的話爲特定設備返回VolumeGUID，如果它與DeviceID匹配的話。

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

上午我剛剛查詢了錯誤的WMI類？

Answer 1

我曾經有VBS這樣做，你可以減少和修改它在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

     wscript.echo "-----"

    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

     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
