Status: offline 		hey all,
i'm having a probelm i want a script to run from a cd-rom drive, so when i manually kick off the script theres code in there to place a call to the script in the windows run key so that after an automatic reboot the run key will point to the script file on the cd-rom drive and it should launch, but i haven't been able to.
I've tried just placing the path to the script in the run key such as:
strMyDrive (which is determined to be like D:\) & "test.vbs"
That didn't work so I tried using the cmd line and run it, but it starts off on the wrong drive and won't run:
"cmd /c wscript.exe " & strMyDrive & "test.vbs"
I'm looking for a way to change the drive of the command line so I can run it or if you know of another way I'd appreciate it.  Thanks.

You have a VBScript that creates a registry key so that on reboot it kicks off another VBScript that resides on your CD-Rom drive?

If you're wanting a script to launch a script off of your CD, then you should be able to use this:

strDrive = "CDRom drive letter"

Set oShell = CreateObject("Wscript.Shell")
oShell.Run strDrive & "\myScript.vbs",0,True

Status: offline 		well see after the reboot I put a call in the Run key of windows in the registry so that it will launch the script file in the CD-Rom.  Basically I need a way to run the script automatically off the reboot.

Status: offline 		Quick question, what are you using to get the letter of the CD?
Also,  just to add to what Country73 said,  Most times when you use WMI/vbscript to return a drive letter you will only get something like this: X:  there is no \ at the end, so you will need to add it.

ex.
On Error Resume Next

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_CDROMDrive")
For Each objItem in colItems
    msg = msg & "before: " & objItem.Drive & vbcr & "After:  " & objItem.Drive & "\" & vbcr
Next
msgbox msg

Status: offline 		well because i'll be manually starting off the script from the cd i just use:
the Wscript.ScriptFullName and just take the first three characters which would be the drive path with "\" already attached to it.

I messed around with mine a little bit and was able to get my script to run from floppy and CD.

When you are retrieving the information for your CD drive, what script is doing that? Does that reside in your Temp directory?

My registry entry:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce    Name: myScript    Type: REG_SZ    Data: D:\myEcho.vbs

D:\ = my CD Drive
This script just launches a msgbox "Hello!"

Status: offline 		so basically the script i run i have it run from the cd-rom itself.
that way when it looks for the current drive its on it will be the drive of the cd-rom
then i tag the registry HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\ with
strMyDrive & "\test.vbs"
so it will look like in the registry:
D:\test.vbs

Now through all my testing after reboots it never seems to run the script.  Is there another way of doing this?
Thanks for all your help so far.

OK, I just tested this again and this should work out for you.

'----------First Script (creates the registry key used for after reboot)---------
'Run_Once_Reg.vbs
'------------------------
Set oFS = CreateObject("Scripting.FileSystemObject")
Set WshShell = WScript.CreateObject("WScript.Shell")
SLOCAL = oFS.GetAbsolutePathName(".")
WshShell.RegWrite "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\Test", SLOCAL & "\myEcho.vbs", "REG_SZ"

'----------Second Script (Just a msgbox to show the registry key took)------------
'myEcho.vbs
'--------------
wscript.echo "Hello!"


Let us know if that works out for you or not.

Status: offline 		I was working on this late Friday night, I'm thinking the call to the script file is working, but I'm wondering if theres some delay time in executing the script from the CD-Rom?  Does WScript not got initialized?  I'm not sure why but when I take my same call to the script file in the Run key and place it in Start -> Run then the script will execute.  Does W2K not allow for scripts to be run if its found in the Run Key?  I've tried everything to putting the Path of the script file, calling wscript.exe before the path, and even using the command window to try and launch it, all with no success.

Status: offline 		Try rulling the CD-Rom out of it.
If you create a basic script at "C:\Temp\myscript.vbs" and then create the registry key to point to it, does the script run that way?

It may take a little longer for the script to start when running from CD. I ran it on my machine and it only took a few seconds, but as soon as I logged in I could hear the CD Drive start up.

Status: offline 		yes running a script from the local hard drive works like a charm.  My project is to get the script to run from the CD-Rom drive however.

It seems to be running from my machine with no problem, so I don't know what the issue might be...

Status: offline 		Here's some more details as to what I'm trying to accomplish, I'm starting the script off using my account, however within my script i create a new local admin account and password that when windows restarts it will automatically auto login into the newly created account from which there it still has the path in the HKLM...Run path to the CD-Rom where the script is to be ran from, however it doesn't run, but when I go back to my own account the script will launch from the CD-Rom.  Any ideas as to why it works on my account and not on the newly created account?  Any suggestions on how I would get this to work?  Thanks for your help this far.

Status: offline 		I don't know what all you have going on with that machine, so I'm just trying to put the peices together in my head.
You create a new account, reboot machine, auto logon with new account, script never runs.

Are there any other applications launching at login?
When the machine is logged into with the new account, does it have access to the CD Drive? Can you manually go in and launch the script while that account is logged into the machine?

Status: offline 		sorry its so confusing...
yes you are correct...
launch script (using my account)...that script creates a new local admin account...reboot machine...auto logon with new account...run key in place to launch script from cd-rom.

no other applications are running.
the new account does have access to the cd-rom drive and it's the same letter.  I can manually go in and launch the script from the new account.

If I just log out and log back into my own account, since the Run Key is still in place it launches the script from the CD-Rom Drive and continues on.

Status: offline 		I really don't think the registry key is the problem, but the script won't launch (from that account) unless you manually launch it from the CD and your regular account will launch the script from the registry key...

Be sure this script is ran from your CD since one variable is created by where the first script is ran from. 
 
Probably a million different ways to write this, but here's one way.
Change / modify what's in RED for your purpose.
 
Set oFS = CreateObject("Scripting.FileSystemObject")
Set WshShell = WScript.CreateObject("WScript.Shell")
SLOCAL = oFS.GetAbsolutePathName(".")
          '=====================
          'Grabs the full path to current script
          '=====================
SSTART = "C:\Documents and Settings\All Users\Start Menu\Programs\Startup\"
          '====================
          'Location to create startup script
          '====================

'=========================================
'Create the startup script
'=========================================
Set myFile = oFS.OpenTextFile(SSTART & "kickOff.vbs",8,True)
   myFile.WriteLine "Set oFS = CreateObject(" & chr(34) & "Scripting.FileSystemObject" & chr(34) & ")"
   myFile.WriteLine "Set WshShell = Wscript.CreateObject(" & chr(34) & "WScript.Shell" & chr(34) & ")"
   myFile.WriteLine "WshShell.Run chr(34) & " & chr(34) & SLOCAL & "\myEcho.vbs" & chr(34) & " & chr(34)"
   myFile.WriteLine "myFile = oFS.GetAbsolutePathName(" & chr(34) & "." & chr(34) & ")"
   myFile.WriteLine "oFS.DeleteFile myFile & " & chr(34) & "\kickOff.vbs" & chr(34)
   myFile.Close
'=========================================================
'The startup script will delete itself once it is launched
'=========================================================
wscript.echo "Startup script created"
