Powershell | Get SharePoint 2010 Custom Error and Access Denied pages

A simple script, run this on any SharePoint server in a farm and it will return all set error and access denied pages for all web applications:

Scenario: Audit of farm setup

Script:
<#
.Synopsis
   Gets all set error and access denied pages for all webapps in the current farm
.EXAMPLE
   get-sperrorpages
#>

function get-sperrorpages()
{
    $snapin = Get-PSSnapin | Where-Object { $_.Name -eq 'Microsoft.SharePoint.Powershell'}
    if ($snapin -eq $null)
    {      
        Write-Host "Loading SharePoint Powershell Snapin"
        Add-PSSnapin "Microsoft.SharePoint.Powershell"
    }

    Start-SPAssignment -global
get-spwebapplication | ForEach-Object {
Write-Host "Web Application: $_" -foregroundcolor Green
Write-Host " - Error Page Set:" $_.GetMappedPage([Microsoft.SharePoint.Administration.SPWebApplication+SPCustomPage]::Error)
Write-Host " - Access Denied Page Set:" $_.GetMappedPage([Microsoft.SharePoint.Administration.SPWebApplication+SPCustomPage]::AccessDenied)
Write-Host ""
}

    Stop-SPAssignment –global
}

Output:
PS C:\dev\scripts\audit> .\get-errorpages.ps1
Web Application: SPWebApplication Name=intranet.devnet.local
 - Error Page:
 - Access Denied Page:

Web Application: SPWebApplication Name=extranet.devnet.local
 - Error Page: /_layouts/Devnet.Local/Error.aspx
 - Access Denied Page: /_layouts/Devnet.Local/AccessDenied.aspx

Web Application: SPWebApplication Name=internet.devnet.local
 - Error Page: /_layouts/Devnet.Local/Error.aspx
 - Access Denied Page: /_layouts/Devnet.Local/AccessDenied.aspx

Web Application: SPWebApplication Name=edit.internet.devnet.local
 - Error Page: /_layouts/Devnet.Local/Error.aspx
 - Access Denied Page: /_layouts/Devnet.Local/AccessDenied.aspx

As you can see from that execution my farm has four web applications, three are publicly accessible so i have set custom error and access denied pages, the fourth is internal only so there is no need for any custom branded pages

Powershell | Get all active RDP sessions for a username

For any IT admin/dev, the ecosystem involves connecting and managing multiple remote desktop sessions to different servers and computers, this can get very cumbersome to maintain and make sure you are disconnecting, many of you probably use mRemote or Remoter Desktop Connection manager to help you manage all of your different connections (if you don't, you really should, its a godsend to be able to categorise and organise all of your connections).

The problem comes in when you have an unexpected crash or an issue and either your computer crashes or the RDP app crashes, you can loose track of which connection you have open, that can lead to leaving sessions open taking up valuable resources or hogging sessions other people need.

That problem can be solved with this powershell script:

<#
.Synopsis
   Gets all server entries from an RDPC connection file and shecks for any open sessons
.EXAMPLE
   get-rdpsessions "C:\resources\rdpSettings.rdg" 'benjamin.dev'
#>
function get-rdpsessions()
{
    Param(
        # link to the RDPC connections file
        $rdcManagerFile,
        # default username to use incase the conneciton entry doesnt have a username set, this should be without the domain
        $defaultUsername)
    
    Select-Xml -XPath '//server' -Path "C:\resources\rdpSettings.rdg" | %{
        $server = $_.node.name
        $userName = $defaultUsername
        if ($_.Node.logonCredentials.HasChildNodes)
        {
            $userName =  $_.Node.logonCredentials.userName
        }
    
        $queryResults = (qwinsta /server:$server | foreach { (($_.trim() -replace “\s+”,”,”))} | ConvertFrom-Csv)
        $queryResults |  %{
            if ($_.SESSIONNAME -eq $userName)
            { 
                write-host 'User:' $_.SESSIONNAME 'is active on' $server -ForegroundColor green
            }
        }
    }
}

get-rdpsessions "C:\resources\rdpSettings.rdg" 'benjamin.dev'

This will output something like the following:

PS C:\Users\benjamin.dev> C:\Users\benjamin.dev\SkyDrive\Code\PS\get-rdpsessions.ps1
User: benjamin.dev is active on devnet-ad.devnet.local
User: benjamin.dev is active on devnet-sql.devnet.local
User: benjamin.dev is active on devnet-sp14.devnet.local
User: benjamin.dev is active on devnet-sp15.devnet.local

This script can be easily modified to integrate with whatever system you use, for example, if you run a development house or consultancy, this could be modified to run through all servers for all users at 4:50 in the afternoon every day and email anyone who has an active session to remind them they need to log off

SP2013: Calling SP.ClientContext for an anonymous user causes "object doesnt support this method"

Good Morning!, and what a wonderful Saturday morning it is, the scent of strawberries are in the air!

So I've been working on a public facing 365 website lately and making a few customisations, one request I received was to have the ability for users to add an item to a "mailing list" list, and they wanted maximum portability, so I thought, perfect for the JS-CSOM!

Such a simple idea, add an item to a list, just needs one field adding in very straight forward, or so I thought, so I created the js function and hooked it up, for auth users it worked like a charm but I ran into a problem when accessing it anonymously, I got the error "object doesn't support this method" when calling a new "SP.ClientContext", its a straight forward error meaning it cant find the function in any loaded libraries, so I thought right, gotta be SP not loading sp.js, simple, add a script link in there... no luck the same error came up, then I thought right, gotta be that the method is running before SP.js is properly loaded so I used "ExecuteOrDelayUntilScriptLoaded()" to encapsulate my code and make sure it runs after the code is loaded, published the js and checked it again... no luck!

So it has to be sp.js not loading correctly, remembering the SoD SharePoint is so fond of I then tried the trusty "SP.SOD.executeFunc('sp.js', 'SP.ClientContext', addToMailingList)", and it worked perfectly!

Code:

$("#ben-mailinglist-confirm").click(function () {
    SP.SOD.executeFunc('sp.js', 'SP.ClientContext', addToMailingList)
});

function addToMailingList(metadata) {
    var metadata = $("#ben-mailinglist-email").val();
    if (metadata != "") {
        var clientContext = new SP.ClientContext("/");
        var list = clientContext.get_web().get_lists().getByTitle('MailingList');

        var itemCreateInfo = new SP.ListItemCreationInformation();
        var listItem = list.addItem(itemCreateInfo);
        listItem.set_item('Title', metadata);
        listItem.update();

        clientContext.load(listItem);
        clientContext.executeQueryAsync(
       Function.createDelegate(this, function () { $(".ben-mailinglist-success").show(); $(".ben-mailinglist-form").hide(); }),
       Function.createDelegate(this, function () { $(".ben-mailinglist-failure").show(); })
   );
    }
    else {
        // validation
    }
}

SharePoint Online (Office365): Profile images broken / not coming up

Today I had a brilliant issue, I have a 365 authenticated site that uses profile images, these are surfaced in the "ContactFieldControl", I added profile pictures to the profiles and navigating to the mysites worked fine and the profile picture on the contactfieldcontrol worked too but then I opened it in a different browser and the profile image was broken in the webpart, that was strange I thought maybe an MS Job had deleted it so I went to the mysite and the image was there!, so I navigated back to the site and once again it shows up

So it appears if the image is loaded through the contact field webpart it shows as a broken image but if you navigate to the mysite or the image directly it worked

So how to fix it?

this issue appears to be in the first load of an image using the direct path to the image, i was hoping a cache clear or an update of the profiles would fix but but to my knowledge there is no OOTB way of fixing this so i resorted to using a dev's best friend, jQuery!

First I tried running a piece of jQuery on the page to preload the image using an ajax call but that didn't work

Then I noticed something interesting, whilst fiddling the page I saw that it also calls the following URL "/_layouts/15/userphoto.aspx?size=S&url=********", this URL links directly to the image, I thought this was interesting so I wrote a piece of jquery to take the source of the image and transform it into a URL like the one above and hey presto it worked!!

Code:
function checkProfileImages() {
    $(".ben-imgborder img").attr("src", "/_layouts/15/userphoto.aspx?size=S&url=" + $(".ben-imgborder img").attr("src"))
}

Installing SharePoint Designer 2013 Issue: You must uninstall office pro plus first....

I came across this issue a while back while setting up a new development environment, i had installed VS2012, Office 2013 and was trying to install SPD 2013, I ran the setup and during the preflight checks it failed with the following message:

Why? why on earth must I un-install office to install SPD?, well as it turns out Office 2013 added a registry key(typical...) that the preflight checks, this key looks as though its not needed but is still added, possibly something that was meant to be deleted but wasn't.

So to fix it!:

Open regedit.exe (Run -> regedit -> Enter)

Find and delete the following key: HKEY_CLASSES_ROOT\Installer\Products\00005102110000000100000000F01FEC 

Note: if you can't find the above key, just find the key with prefix: 00005102, and suffix: F01FEC, and delete it. (Before deleting it, backup this key by exporting it, never a good idea to mess with the registry before backing up the original state).

Now that that's gone, try the installer again, hopefully it should now let you install SPD unhindered! 

Using the C# CSOM to interact with SharePoint Online

So, I had a requirement recently to allow a client to interact with their SPOnline site from their on-prem network, essentially being able to sync data from their on-prem LoB apps to their SPOnline site.

As any sp dev knows there is one main way of interacting with SharePoint remotely, that is through the supplied web services, this can be done either through interacting directly with the web services or by using the SharePoint client site object model which essentially just wraps a basic API around the web services, so its your preference on what you want to use.

Now with the CSOM any interactions with SharePoint are based around the context, to set up the context you need to pass in the credentials and authenticate the accessing user, in SP 2010 this was a feat to accomplish as there was no real way to pass in an authentication token to the context, with the release of SP2013 MS have made this significantly simpler, you can call in a class called "SharePointOnlineCredentials" this will handle any authentication you should need to do. this class is included in version 15 of the Microsoft.SharePoint.Client dll

Depending on how you have your dev environment set up you may encounter a "FileNotFoundException" pointing to "MSOIDCLIL.dll" this usually occurs if you have VS installed locally and have installed the dev tools but you haven't installed the client sdk, you can check this by navigating to this directory "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\Client", if that dir exists and has the dll then there is a broken link somewhere and you will need to reinstall the sdk, if it doesn't exist then a fresh install of the SharePoint Client SDK here.

By using this you now have open to you the full array of functions you can call with the CSOM that you can now call from your on prem network

Here is the code I have used to PoC the process, please use it as you see fit:

    class Program

    {

        static void Main(string[] args)

        {

            args = new string[] { "CreateProjectList" };

            if (args.Length != 1)

            {

                Console.WriteLine("Instanciate the program with a method parameter:");

                Console.WriteLine(" - GetLists");

                Console.WriteLine(" - CreateProjectList");

            }

            else

            {

                switch (args[0])

                {

                    case "GetLists":

                        Console.WriteLine("Getting lists from Online Site");

                        GetLists();

                        Console.WriteLine("List retrieval complete");

                        break;

                    case "CreateProjectList":

                        Console.WriteLine("Creating projects list in Online Site");

                        CreateProjectList();

                        Console.WriteLine("List creation complete");

                        break;

                }

                Console.ReadKey();

            }

        }

        private class Configuration

        {

            public static string ServiceSiteUrl = "https://{mysite}.sharepoint.com";

            public static string ServiceUserName = "{user}@{365-org}.onmicrosoft.com";

        {

            var securePassword = new SecureString();

            foreach (char c in Configuration.ServicePassword)

            {

                securePassword.AppendChar(c);

            }

            var onlineCredentials = new SharePointOnlineCredentials(Configuration.ServiceUserName, securePassword);

            var context = new ClientContext(Configuration.ServiceSiteUrl);

            context.Credentials = onlineCredentials;

            return context;

        }

        static void GetLists()

        {

            var context = GetContext();

            var results = context.LoadQuery(context.Web.Lists.Include(list => list.Title, list => list.Id));

            context.ExecuteQuery();

            results.ToList().ForEach(x =>

            {

                Console.WriteLine("List: " + x.Title);

            });

            context.Dispose();

        }

        static void CreateProjectList()

        {

            ClientContext clientContext = GetContext();

            Web site = clientContext.Web;

            // Create the project list.

            ListCreationInformation listCreationInfo = new ListCreationInformation();

            listCreationInfo.Title = "Projects";

            listCreationInfo.TemplateType = (int)ListTemplateType.GenericList;

            List list = site.Lists.Add(listCreationInfo);

            // Add the category field to the list.

            Field catField = list.Fields.AddFieldAsXml(@"

                <Field Type='Choice' DisplayName='Category' Format='Dropdown'>

                    <Default>IT</Default>

SharePoint Issue: Exception has been thrown by the target of an invocation while adding a CQWP

Summary Info:
SharePoint Version: 2010 Standard
OS:Windows 2008 R2

So, Yesterday I had another fantastically inexplicable issue.

I have this solution, this solution deploys a site definition, when the site is created, it activates a custom feature that processes the more complex requirements of the site, including some CQWP's whereby you been to set the listguid and weburl properties.

This solution was build and on both Dev and UAT it worked like a dream, but then it came to the production deployment, solution deployed, features activated, everything was looking rosey, until I tested creating a site, then boom "an unexpected error has occurred for correlation id.....", so there was me thinking there is an issue with the deployment that got glazed over, I checked the ULS logs for the correlation and there I found:

 Error Message   Exception has been thrown by the target of an invocation.   
  Error Stacktrace:  at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner)

   at {Logic Namespace}.AddCQWebPart(SPWeb rootWeb, SPLimitedWebPartManager webPartManager, String webpartName, String zoneId, Int32 zoneIndex, Guid listId, String url)  

What! what the hell is that!, the content query web part couldn't be added, OK!,  well that could be one of many issues:

• SharePoint feature corruption
• CQWP I'm referencing isn't there
• Namespace is invalid
• Couldn't set the properties

So I checked the webpart in the gallery, it looked ok, I added a webpart to the page through the UI, configured it to look at the list and it worked! so the .webpart is fine, the namespace and features are fine, so it looks like the property setting.

I removed the code setting the properties and still the error occurred  so as a process of deduction i took property after property out of the webpart until i found the properties breaking it, after taking the MainXsl, HeaderXsl and ItemXsl properties out of the .webpart file, the web parts deployed, why? good question!

So the SC I was deploying to was root and at "/" of the webapp so it cant be the URL of the properties.

Just to make sure I programatically set the urls of the xsl to the correct urls, when I did this I got another error!

 Error Message   Object reference not set to an instance of an object.   
  Error Stacktrace:  at Microsoft.SharePoint.Publishing.WebControls.CmsDataFormWebPart.MakeSiteRelativeUrl(String xslServerRelativeUrl)  
   at Microsoft.SharePoint.Publishing.WebControls.CmsDataFormWebPart.SetXSLLink()  
   at {Logic Namespace}.AddCQWebPart(SPWeb rootWeb, SPLimitedWebPartManager webPartManager, String webpartName, String zoneId, Int32 zoneIndex, Guid listId, String Url, String& errorMessage)  
   at {Logic Namespace}.AddCQPageWebPart(String pageUrl, String webPartName, String webPartZone, String listName)  

Ok now we're getting further down the rabbit hole!

Then I started investigating the context properties programmatically and found that when deploying this the HttpContext was null. I know this has been known to mess up some context sensitive operations. so I added the following before I attempted to instantiate the webpart to add:

 if (HttpContext.Current == null)  
 {  
      HttpRequest request = new HttpRequest("", rootWeb.Url, "");  
      HttpContext.Current = new HttpContext(request, new HttpResponse(new StringWriter()));  
      HttpContext.Current.Items["HttpHandlerSPWeb"] = rootWeb;  
 }  

and viola! the web part started to deploy!

So in conclusion, the CQWP is very context sensitive, and to do anything programatically, make sure you have access to a HttpContext
