Registry deletion

[nikhil2010]

Hi I want to write vbscript code
req is like I want to delete the whole branch say

I have a subkey called "A" Under that whatever comes it should be deleted. But I think vb doesnt allow to do unless we delete everything under that.

How do I do that??

PHV sorry I'm new to that I learnt Wshell to perform normal deletion but the help content you gave seems to be completely different!!

 

[mrmovie]

PHV's link was to the WMI classes for registry manipulation, rather than using WshShell.
this is MS's link for the .RegDelete method of Wscript.Shell

p.s. i am guessing you will get a run time if you try and delete a registry key which has subkeys using WshShell.RegDelete, and hence PHV's post

Yeah it doesnt allow to delete whole branch unless I delete entries below that. I tried Is any other technique something where I can delete whole branch??

 

[nikhil2010]

PHV thanks for the link I got the class articles, but one doubt

what is meaning of this code

Set objReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\"&_
strComputer & "\root\default:StdRegProv")
I know its creating WMI object and getting a reference but no explanation is given is much for this.. Can you help?

 

[mrmovie]

this is an equivelance of you doing (sort of)

Set WshShell = CreateObject("Wscript.Shell")

By doing the Set objReg = GetObject("winmgmts...etc you are connecting to the WMI of the strComputer and specifically connecting to the StdRegProv (standard registry provider) provider, this will then give you access to that providers Methods and Properties, e.g. RegDelete EnumKeys etc

i believe the funny binding strings are refer'd to as 'moniker' strings

tsuji its complex but thanks now How do I understand or rather what should I read first before going thru winmgts ...... Im quite new to this..

 

[mrmovie]

taken from an activeexperts example on scripting the registry:

Const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
strComputer & "\root\default:StdRegProv")
strKeyPath = "SOFTWARE\System Admin Scripting Guide"
oReg.DeleteKey HKEY_LOCAL_MACHINE, strKeyPath

You'll have to enumerate (to list one by one) each subkey/subvalue in the parent registry key and delete them first before deleting the parent key. Keys can't be deleted using WMI unless they are empty (from what I understand).

Here is the link that mrmovie alluded to.

i dont know if regedit.exe using the - to delete a registry key will delete the subkeys as well, i know it strictly not vbscript but it might be what you are after

for a less robust, "git'r done" approach, review the dos cmdline "reg"
