Get drive letter and label?

[Diana (Cda)]

I don't know what I did wrong but after searching forum and help file found DriveGetLabel. The script I made is showing up blank despite the fact that all my drives have labels.

What did I do wrong here, pls?:

;================================================
$var = DriveGetLabel(@ScriptDir & "\")
;================================================
MsgBox(4096,"Volume Label: ","The drive label is:  " & $var & "       ")

Further, it would be nice for the message box to have the output like this:

D = UFD

p.s., When I put the actual drive letter in ("D:" instead of "@ScriptDir & "\""), I got the desired output of "UFD" but I'd prefer to use @ScriptDir so that this one script works in any folder to know what the root volume drive letter and volume are.

Thanks!

you must indicate Path of drive to receive information from.

Like c:\ or D:\ ..

you can see for _PathSplit function.

Then you should perhaps take a look at the requirements for DriveGetLabel() and the return of @ScriptDir.

Try this instead

$var = DriveGetLabel(StringLeft(@ScriptDir, 2))

EDIT"

Also this one

$var = DriveGetLabel(StringLeft(@ScriptFullPath, 2))

Oh, okay. I don't understand why what you did with DriveGetLabel works rather than just with the command but the good thing is that they both work! <vbg> Thanks. They don't give the drive letter but they give the volume name, which is great. I have 2 folders I open up with a script that are identical, just that one is on the hdd and the other on the usb stick. With the script the drive label will help me know at a glance which one I'm on. I prefer to work on the financials on the hdd and then copying them over to the usb stick rather than vice versa.

Thanks.

---------------------

p.s., to get the drive letter to also be displayed, what command would we use, pls? Is there anything?

If there is a way, I'd then use this script:

;================================================
$var = DriveGetLabel(StringLeft(@ScriptDir, 2))
;================================================
MsgBox(4096,"Volume Label: ","The drive is:  " & @CRLF & @CRLF & [drive letter] & " = " & $var & "       ")

where [drive letter] would be where that AutoIt command would go.

Just out of curiousity.

$driveletter=StringLeft(@ScriptDir, 2)

[GEOSoft]

Func _ExtractDriveFromPath($vPath)
    Return StringLeft($vPath, 2)
EndFunc

Unless of course you want me to get fancy and do it with StringRegExpReplace() and an extra parameter to include the back-slash (or not).

Here another method using WMI:

;coded by UEZ 2011
#AutoIt3Wrapper_Change2CUI=y
#AutoIt3Wrapper_UseUpx=n
#include <Array.au3>

$oMyError = ObjEvent("AutoIt.Error", "oMyError") ; Install a custom error handler

Global $ip = "localhost"
If $CmdLine[0] > 0 Then $ip = $CmdLine[1]

$objWMIService = ObjGet("winmgmts:{impersonationLevel = impersonate}!\\" & $ip & "\root\cimv2")

$aMyDriveLabels = GetWMI($ip)
_ArrayDisplay($aMyDriveLabels)

Func GetWMI($srv)
    Local $DriveLabel, $sDriveLabels, $i
    Local $aDriveLabels[26][2]
    $colItems = $objWMIService.ExecQuery("SELECT Name, VolumeName FROM Win32_LogicalDisk", "WQL", 0x30)
    If IsObj($colItems) Then
        For $objItem In $colItems
            $aDriveLabels[$i][0] = $objItem.Name
            $aDriveLabels[$i][1] = $objItem.VolumeName
            $i += 1
        Next
    EndIf
    ReDim $aDriveLabels[$i][2]
    Return $aDriveLabels
EndFunc

Func oMyError()
  Msgbox(0,"AutoItCOM Test","We intercepted a COM Error !"      & @CRLF  & @CRLF & _
             "err.description is: "    & @TAB & $oMyError.Description    & @CRLF & _
