Novice question on VBScript

Hello folks,

I'm working on a writing a VBScript and I have no experience with VBS.  I can do this with a command line with no problem, however, it needs to be in VBS.

The script I'm working on checks to see if 2 registry key exist, and if so, deletes a third key.  I've been looking around on the net and found some code that works for what I want to do.  My issue is on the delete RegKey code.  I found this code which works fine, however, if I modify it to point to a different location, it doesn't work.

Here is the code I found and if I put a key in the registry, it deletes it just fine:  HKCU\Software\Test

Const HKEY_CURRENT_USER = &H80000001 

strComputer = "."
strKeyPath = "Software\Test" 

Set objRegistry = GetObject("winmgmts:\\" & _
    strComputer & "\root\default:StdRegProv") 

DeleteSubkeys HKEY_CURRENT_USER, strKeypath 

Sub DeleteSubkeys(HKEY_CURRENT_USER, strKeyPath) 
    objRegistry.EnumKey HKEY_CURRENT_USER, strKeyPath, arrSubkeys 

    If IsArray(arrSubkeys) Then 
        For Each strSubkey In arrSubkeys 
            DeleteSubkeys HKEY_CURRENT_USER, strKeyPath & "\" & strSubkey 
        Next 
    End If 

    objRegistry.DeleteKey HKEY_CURRENT_USER, strKeyPath 
End Sub

Open in new window


But if I change the code to this, it doesn't work.  What am I doing wrong?  HKLM\Software\Test

Const HKEY_LOCAL_MACHINE = &H80000002 

strComputer = "."
strKeyPath = "Software\Test" 

Set objRegistry = GetObject("winmgmts:\\" & 
    strComputer & "\root\default:StdRegProv") 

DeleteSubkeys HKEY_LOCAL_MACHINE, strKeypath 

Sub DeleteSubkeys(HKEY_LOCAL_MACHINE, strKeyPath) 
    objRegistry.EnumKey HKEY_LOCAL_MACHINE, strKeyPath, arrSubkeys 

    If IsArray(arrSubkeys) Then 
        For Each strSubkey In arrSubkeys 
            DeleteSubkeys HKEY_LOCAL_MACHINE, strKeyPath & "\" & strSubkey 
        Next 
    End If 

    objRegistry.DeleteKey HKEY_LOCAL_MACHINE, strKeyPath 
End Sub

You have a variable strKeyPath, but I do not see that variable assigned.  Don't know if that is the problem, but I would look at that.  Also are you using anything like notepad++ to write this?
What line is the error on...?  You can put on error resume which may make it work.

I'm using MetaPad and verified that it's a DOS VBS file.  The only thing I changed is the first line:

Const HKEY_CURRENT_USER = &H80000001

to

Const HKEY_LOCAL_MACHINE = &H80000002

and all instances of HKEY_CURRENT_USER to HKEY_LOCAL_MACHINE.  The first one works fine, but the second one doesn't.

Looks like I also have a typo in the second script.  In line 6 I forgot the underscore, but it's there in the script I have.

I forgot the underscore
that's why you should always include an Option Explicit statement

HKCU keys are for the current user and are readable/writable by the current user.  However, HKLM keys are shared by all users and are read-only by all users.  In order to modify an HKLM key you need to run the script with elevated permissions (aka as administrator).

OK, so I've tried to use this to elevate the permissions, but it's STILL not working.  My script name is Axcess-regkey.VBS and it's in the same directory.

Set objShell = CreateObject("Shell.Application")
Set FSO = CreateObject("Scripting.FileSystemObject")
strPath = FSO.GetParentFolderName (WScript.ScriptFullName)
     objShell.ShellExecute "wscript.exe", _ 
        Chr(34) & strPath & "\Axcess-regkey.VBS" & Chr(34), "", "runas", 1

Jody,
Your exact code (with the correction you mentioned above) works perfectly for me.
