get drive letter based on label

[pcjunki]

i have a flash drive with the volume label called "data"

but if i plug this into multiple computers, the drive letter will change, ect ect

and i want to populate the drive letter into my gui input

here is what i have so far,

$var1 = DriveGetLabel("data")
$var2 = DriveGetDrive("$var1")


$Input1 = GUICtrlCreateInput($var2, 16, 56, 281, 28)

am i close?

DriveGetDrive requires a type, not a name. Also, if you're going to use a variable, you can't put it inside quotes like that.

DriveGetLabel needs a path to the drive.

You should probably use DriveGetDrive using Removable as the type, then loop through the array with DriveGetLabel using the contents of the array, to get the drive with the right name.

Something like this should work, untested though.

Local $aArray = DriveGetDrive("removable")
If @error Then
    ; An error occurred when retrieving the drives.
    MsgBox(4096, "DriveGetDrive", "It appears an error occurred.")
Else
    For $i = 1 To $aArray[0]
        If DriveGetLabel($aArray[$i]) = "data" Then
            MsgBox(4096, "DriveGetLabel", "Drive " & $aArray[$i] & " found with the label Data')
        EndIf
    Next
EndIf

Just a little modify to BrewManNH code, this will skip the floppy drive from the loop. If you have a floppy drive installed on your pc, DriveGetLabel("floppydriver") can be very slow, for example in my system take ~ 3sec.

Local $aArray = DriveGetDrive("REMOVABLE")
If @error Then
    ; An error occurred when retrieving the drives.
    MsgBox(4096, "DriveGetDrive", "It appears an error occurred.")
Else
    For $i = 1 To $aArray[0]
        If $aArray[$i] = "a:" Then ContinueLoop ;Usually assigned to floppy driver, yep i still have a floppy drive in my pc :P
        If DriveGetLabel($aArray[$i]) = "data" Then
            MsgBox(4096, "DriveGetLabel", "Drive " & $aArray[$i] & " found with the label Data")
        EndIf
    Next
EndIf

If your script resides on the flash drive, then you can get the drive letter like this

$var2 = StringLeft(@ScriptDir, 2)
$Input1 = GUICtrlCreateInput($var2, 16, 56, 281, 28)

So if @ScriptDir is G:folder then $var2 would be G: as StringLeft returns the first 2 characters as shown above
