CD-ROM open/close (with letter in command line)

[Eugen]

Hello all!
I used to manage the state of my real CD-ROM from the keyboard. I have successfully used a free program HotKey Manager from here http://www.killprog.com/indexe.html.
But this program works correctly only if the real CD-ROM have the letter in the system before the letter of the virtual CD-ROMs.
What do if the CD-ROM has the letter 'Z'?
AutoIT helps!
The text of the script below

#NoTrayIcon

#include <WinAPI.au3>
#include <FileConstants.au3>
#include <MsgBoxConstants.au3>


If $CMDLINE[0] = 0 Then
    MsgBox($MB_SYSTEMMODAL, "No parameter", "Please use parameter: letter of CD-ROM. For example, 'E:'")
    Exit
EndIf

If $CMDLINE[0] = 1 Then
    Global $Drive_Letter = $CMDLINE[1]
    ;MsgBox($MB_SYSTEMMODAL, "Drive_Letter", $Drive_Letter)
EndIf
;Exit

Example()

Func Example()

    ; Create a constant file name.
    Local Const $sFile = "CD_Open.txt"

    ; Open the file for reading and store the handle to a variable.
    Local $hFileOpen = FileOpen($sFile, $FO_READ)
    If $hFileOpen = -1 Then
        ;MsgBox($MB_SYSTEMMODAL, "", "An error occurred when reading the file.")
        ; open CR-ROM, create temporary file and Exit
        CDTray($Drive_Letter, "open")
        Local $hFile = _WinAPI_CreateFile($sFile, 1)
        Return True
     Else
        ; close CD-ROM and delete temporary file
        CDTray($Drive_Letter, "close")
        FileDelete($sFile)
    EndIf

    Return True
EndFunc   ;==>Example

@Eugen - Welcome to the Forum!

I'm presuming your code is a useful example, and this is not a question, that should be posted in the Q&A section of the Forum.

It would be easier to tell, if you used the AutoIt code tags (quoting) for your code, which makes it eminently more readable.

See the button to the immediate left of the quote balloon button, which is to the left of the paw print button in the post editor.
