Powershell to add Read permission on all files in a directory

Recently I needed to update all the files in a specific directory, adding Read permission for the "Users" NTFS group. Here is a Powershell script to do that. It can be easily modified to update other users/groups or different permission sets.

$base = "C:\somefolder"

$files = get-childitem $base

foreach ($file in $files) {

$Acl = Get-Acl $file.FullName

$Ar = New-Object system.security.accesscontrol.filesystemaccessrule("Users","Read","Allow")

$Acl.SetAccessRule($Ar)

Set-Acl $file.FullName $Acl

}

Basic rules for using ResolveClientUrl in master pages (ASP.NET)

When writing ASP.NET Web Forms, the basic rules for using ResolveClientUrl in master pages are:

<img src="<%= ResolveClientUrl("~/x/resource.jpg")%>" />

<script src="<%= ResolveClientUrl("~/x/resource.js")%>"></script>

If you want to use ResolveClientUrl in the master page <head> section for script tags:

<asp:PlaceHolder ID="PlaceHolder1" runat="server">
   <script src="<%= ResolveClientUrl("~/x/resource.js")%>"></script>
</asp:PlaceHolder>

You do not need to use ResolveClientUrl for CSS link elements in the <head> section (they will automatically be resolved by ASP.NET).
