Subject: Changing file/folder permissions
Hi All

I understand I can call the cacls command from a VB script to alter
permissions on files/folders.

I was just wondering if there is a pure VB way of doing this?

Changing permissions of a folder on a PC which is a member of a domain (if
that makes a diff?)

Thanks
gerryR

There is a way but it is much easier to use cacls or xcacls from the resource
kit

The script below is an example of how to set share and ntfs permissions

'ShareSetup.vbs

'Requirements: Admin Rights

'Some Addition Lev Shumskii aka WildCat
'Now You may set SecurityDescriptor for NTFS
'and this script work properly under Win2k & Win2k3

  Are you sure you mean VB? VBScript is not
the same as VB, and what Jon posted was not
"pure" of either. It was VBScript using WMI.

VB would use the Windows API, like this:
http://support.microsoft.com/kb/295004/

  Then there's also VB.Net, which Microsoft is now
calling just "VB". VBScript, VB and VB.Net are all
entirely different things that would usually use
entirely different methods.

   WMI is a scriptable set of methods that runs as a
service on NT systems and provides a number of
functions (mainly related to network administration
chores) that VBScript would otherwise not have
access to.

Hi Mayayana

Yeah I meant VBScript, forgot that abbreviating it changed it to an entirely
different language ;)
