Requirement

Generate a list of SCAs across all your SharePoint site collections.

Solution

function Get-SCA {
param($site)
$link = $site+"/_layouts/mngsiteadmin.aspx"
 
$result = Invoke-WebRequest $link -UseDefaultCredentials
 
$value = $result.AllElements |
Where id -eq "ctl00_PlaceHolderMain_ctl00_PeopleEditorAdmins_OriginalEntities" |
Select value
$value = $value.value.split(">") | where { $_ -match "displaytext" }
$value = $value.split("`"") | where { $_ -notmatch "=" -and $_ -notmatch "ct" -and $_ -notmatch "true" -and $_ }
#$value = $value -join ' '
return $value
}

To use the above function:
Syntax: Get-SCA -site <site collection url>

You can then use this function within a loop to iterate through all your site collections to generate a list of SCAs.

Automatically download versions of a file in SharePoint to your computer

Requirement

Download all versions of a file in SharePoint to a local folder on your computer.

Solution

Use the PowerShell script below to do this. You can run this script as a normal user as long as you have access to the GetVersions webservice method.

Usage: Run the script in PowerShell or PowerShell ISE.

Parameters:

Site URL: for e.g. http://www.google.com

File URL: for e.g. http://www.google.com/testfile.docx

Path to local folder: for e.g. c:\download\

# Download all versions of a file to a local folder.
# Instructions: Specify the URL of the file you wish to download.
# Last Updated: 12-06-2014.
# By: Andrew Toh
 
$scriptpath = $MyInvocation.MyCommand.Path
$dir = Split-Path $scriptpath
 
# Get parameters
$site = Read-Host "Enter Site URL"
$file = Read-Host "Enter full URL to file, e.g. http://www.google.com/sample.docx"
$localdir = Read-Host "Enter path to local folder, e.g. c:\downloads"
$filename = $($file.split("([^/]+$)'")[-1])
$filedir = "$($localdir)\$($filename)"
 
#----------------------------------------------------- functions -----------------------------------------------------------
 
function GetVersions()
{
     param($site, $file)
     $uriWeb=$site+"/_vti_bin/Versions.asmx?wsdl" 
     $service = New-WebServiceProxy -Uri $uriWeb -UseDefaultCredential 
     [System.Xml.XmlNode]$webCollXmlNode=$service.GetVersions($file)
     $vers = $webCollXmlNode.result
     return $vers        
}
 
#--------------------------------------- Work with the data ------------------------------------------
 
$versions = GetVersions -site $site -file $file
mkdir -path $filedir
$webclient = New-Object System.Net.WebClient
$webclient.UseDefaultCredentials = $true
$webclient.DownloadFile($file, "$($filedir)\$($filename)")
 
# Download all versions of a file
foreach ($ver in $versions)
{
    $verpath = "$($filedir)\$($ver.version)"
    mkdir -path $verpath
    $webclient = New-Object System.Net.WebClient
    $webclient.UseDefaultCredentials = $true
    $webclient.DownloadFile($ver.url, "$($verpath)\$($filename)")
}

When the script has run, a folder will be created with all the downloaded versions of the file. Using the parameters in the example above, you will get a folder called:

c:\working\testfile.docx

Assuming there are 4 versions:

Folder contents:

c:\working\testfile.docx\@3.0\testfile.docx

c:\working\testfile.docx\2.0\testfile.docx

c:\working\testfile.docx\1.0\testfile.docx

c:\working\testfile.docx <- latest version (4.0).

SharePoint 2010 Service Pack 2 breaking scripts using SPServices / jquery

Problem:

We have some scripts that use jQuery Library for SharePoint Web Services. After installing Service Pack 2 for SharePoint 2010, several of the scripts stopped working.

Cause:

We found that the script renamed the form control titles if the field was a mandatory field.

For example:

If you have a required /mandatory field called ‘Classification’ in your SharePoint list  and you make a reference to the form control in the EditForm.aspx page. You will get a javascript ‘null’  error stating that the script is unable to find the value. If you look in the page source, you will find that the form control title has been renamed to ‘Classification Required Field’.

Solution:

You will need to update your script to reference the new field name, i.e. ‘Classification Required Field’.
