Subst

[saywell]

The DOS subst command lets you use a folder as a designated drive letter. Is this possible in AotoIT?

Also, can drive letters be changed.

I need to re-allocate a CD drive to another letter, then subst a folder so it appears to be the original CD cdive letter. This is to work around some software that can ONLY look at the CD drive for data input.

If anyone could point me in the right direction, I'd be grateful.

Thanks,

William

This is an example to delete and recreate driveletters:

expandcollapse popup

$KERNEL32 = DllOpen("Kernel32.dll")

$szVolumeMountPoint = "E:\" ; The Drive Letter with Backslash
$szVolumeName = _GetVolumeNameForVolumeMountPoint($szVolumeMountPoint) ; get the VolumeName, needed to recreate it afterwards
If Not @error Then
    MsgBox(0, 'VolumeName', "Dirveletter " & $szVolumeMountPoint & " is connected with volume:" & @CRLF & $szVolumeName)
    $success = _DeleteVolumeMountPoint($szVolumeMountPoint)
    If $success Then
        MsgBox(0, 'Delte Colume', "The driveletter is removed. It will be recreated when you click OK")
        $success = _SetVolumeMountPoint($szVolumeMountPoint, $szVolumeName)
        If $success Then 
            MsgBox(0, '', "The driveletter is recreated.")
        Else
            MsgBox(0, '', "Could not recreate the driveletter.")
        EndIf
    Else
        MsgBox(0, '', "Could not remove the driveletter " & $szVolumeMountPoint )
    EndIf
Else
    MsgBox(0, '', "Could not get the VolumeName for " & $szVolumeMountPoint)
EndIf

Func _GetVolumeNameForVolumeMountPoint($szVolumeMountPoint)
    ; Prog@ndy
    Local $pszVolumeName = DllStructCreate("wchar[51]")
    Local $success = DllCall($KERNEL32, "int", "GetVolumeNameForVolumeMountPointW", "wstr", $szVolumeMountPoint, "ptr", DllStructGetPtr($pszVolumeName), "dword", 51)
    If @error Then Return SetError(2,0,"")
    Return SetError($success[0]=0,0,String(DllStructGetData($pszVolumeName,1)))
EndFunc

Func _DeleteVolumeMountPoint($szVolumeMountPoint)
    ; Prog@ndy
    Local $success = DllCall($KERNEL32, "int", "DeleteVolumeMountPointW", "wstr", $szVolumeMountPoint)
    If @error Then Return SetError(2,0,0)
    Return SetError($success[0]=0,0,$success[0])
EndFunc

Func _SetVolumeMountPoint($szVolumeMountPoint, $szVolumeName)
    ; Prog@ndy
    Local $success = DllCall($KERNEL32, "int", "SetVolumeMountPointW", "wstr", $szVolumeMountPoint, "wstr", $szVolumeName)
    If @error Then Return SetError(2,0,0)
    Return SetError($success[0]=0,0,$success[0])
EndFunc

Those functions only work with real hardware. (so those are meant to remove and recreate your CD-Drive)

The SUBST-command can be simulated with these funcs: http://www.autoit.de/index.php?page=Thread...69362#post69362 This is the translated UDF-info:

;==================================================================================================
; Function Name:   _PartialDrive($sDeviceName=-1, $sTargetPath=-1, $iDelete=0)
; Description:: Creates or removes a Virtual Drive. The Drive will

;                                                       Delete: the path connected with the driveletter will be found automatically.
;    optional:  $iDelete            0=Creation (default); 1=Deletion of the Drive
; Return Value(s): Success          Driveletter of the created/deleted virtual Drive
