Get and Set User in Client People Picker using Javascript Client Object Model

2013-05-31T00:23:00.002-07:00

Hi Readers,

There is a unique scenario where I have to pick user from a Custom People Picker on a Custom Form and then Push that User to a Client People Picker of a List Item using Javascript Client Object Model.

InOrder to achieve this functionality, I first tried to fetch the User from the Custom People Picker on the Form using JQuery,

var displayName = $("span.ms-entity-resolved div:first-child").attr("displaytext");

Problem is I do not get the ID of this User normally. So inorder to get the 'Id' of this User I searched this User into UserInformation List and then picked the ID of this User.

function AddItems(displayName) {

var userInfoList = siteObjects.web.get_siteUserInfoList();
var query = new SP.CamlQuery();
query.set_viewXml("<View><Query><Where><Eq><FieldRef Name='Title' /><Value Type='Text'>" + displayName + "</Value></Eq></Where></Query></View>");
siteObjects.UserCollListItem = userInfoList.getItems(query);
siteObjects.ctx.load(siteObjects.UserCollListItem);
siteObjects.ctx.executeQueryAsync(Function.createDelegate(null, AddItemsSuccess), Function.createDelegate(null, AddItemsFailure));
}

Then I fetched the List Item ID : userID = currentItem.get_item("ID");

Once I got the User ID , I can easily convert this String Type User into User Type using below code :

var userFV = new SP.FieldUserValue();
userFV.set_lookupId(userID);

and can easily set the People Picker List Item now

siteObjects.UserCourselistItem.set_item('UserName', userFV);

This is something very unique requirement and can be helpful for many.

How to Ensure User using JavaScript Client Object Model

2013-05-31T00:14:00.000-07:00

Hi Readers,

In Server Object Model, web.EnsureUser(loginName) checks whether the user is there in the sharepoint site and if not present , it automatically adds that user into the site.

Similarly using Client Object Model, Microsoft has introduced in same fashion using ECMA Client Object Model we can achieve same functionality.

In microsoft link below you might get to see this approach but if you try to use the same exact way it might not turn fruitful to you.
http://msdn.microsoft.com/en-us/library/ff408786(v=office.14).aspx

The reason why it is not working for you is only because you need to 'esureuser' on correct 'web' context.
i.e. Try to initiate separate context for this command and then asyc the load objects.

function EnsureUser(loginName) {
var context = SP.ClientContext.get_current();
siteObjects.currentUser = context.get_web().ensureUser(loginName);

context.load(siteObjects.currentUser);
context.executeQueryAsync(Function.createDelegate(null, ensureUserSucess), Function.createDelegate(null, ensureUserFailure));
}

I hope this will be helpful

How to get People Picker entry using JavaScript Client Object Model

2013-05-31T00:07:00.001-07:00

Hi ,

To fetch People picker value from People Editor Control, JQuery comes to rescue when we talk in terms of Javascript Client Object Model.

Approach 1 :
var loginName = $("span.ms-entity-resolved").attr("title"); // Returns the Login Name eg. ind\ali.yasir
var displayName = $("span.ms-entity-resolved div:first-child").attr("displaytext"); Returns Display Name as 'Ali Yasir'

Approach 2:
var loginName = $("textarea[title='People Picker']").val();
var displayName = $("div[title='People Picker']").text();

Hope this will help !!

What is OAuth ???

2013-05-26T20:42:00.002-07:00

Hi All,

I came across a nice post on OAuth so couldn’t stop myself sharing this with you all.

Here is a long description which needs patience to read J , Hope you will like this :

Before I go straight to the definition of OAUTH and its elaboration, let’s talk about few things we already know to set the context. Also, my discussion on OAuth below is very generic and is not specific to SharePoint now. Once we are clear of OAuth concepts, we will see on SharePoint OAuth implementation in another upcoming post.

Apps: We all know what Apps are by now. The word App is so common now a days that I hope to see the nursery books replacingA for Apple with A for Apps Well, at least for me A is for Apps.

Service: We all understand the idea of Service. A Service can be a Web Service or API that is consumed by client applications

Service consumer : Any application that consumes a service. Now tell me what’s is the most common breed of application now-a-days that consume the Services?….guess… APPs! Yes, Apps are the most common Service Consumers now-a-days.

Service Provider: It’s the one who hosts the service and where the service runs. The service generally requires authentication so that only trusted consumers can access the restricted functionality or data offered by the service.

Now, imagine as a developer, you have developed an enterprise application that offer users to play some interesting games on their Mobile devices. For that, you created a Windows 8 or iOS App (or any App) whose main function is to entertain user via some puzzle games on his mobile device.

Now, a new requirement is to allow the user to share the score on his Facebook timeline via your App.

How can you make your App share the information on Facebook on behalf of User?

Isn’t it a most common and necessary requirement now-a-days? It is.

You will need to access the Service provided by Facebook (Service Provider) and authenticate your App to post on behalf of the User. An obvious solution is to ask User to provide his Facebook credentials and store it securely with you (in your DB\config or whatever). Now, whenever the user wants to share his score, your App will use the stored credentials and post on the Facebook wall on behalf of user.

With this (bad) solution, below uncomfortable questions arise around Security, Maintenance, and User Experience.

1. Security: Is it good to ask User for his Facebook credentials and store them with your application?
Although a user may enjoy playing with your App but he will most likely hesitate to provide you what you are asking. Of course, he cannot simply trust you!

2. Maintenance: What if you want to provide the same functionality with other social platforms like Twitter, LinkedIn or Yammer? Also, it will be difficult to maintain the user credentials for all the platforms you have integrated and also keep them in sync in case the User updates his account at Facebook, Twitter, and Yammer etc.

3. User Experience: If your App makes a User feel insecure about his social accounts, he will simply abandon your App. How can you prevent it? One solution is that instead of storing credentials, you can also present a login page when he can supply credentials. However, if your App connects with many Service Providers (Facebook, Twitter, LinkedIn, Yammer and many more upcoming) and you keep on asking the credentials every time, the user will not feel your App is really integrated . Isn’t it?

The solution to all above questions is OAUTH - an open protocol to allow secure authorization in a simple and standard method from web, mobile and desktop applications.

OAUTH

OAuth is a standard way for Service providers and Consumers(Apps for example) to handle authentication. Also, the OAuth authorization framework enables a third-party application to obtain limited access to a service hosted by Service provider. By using OAuth, you can allow the user to access a service (Facebook wall for example) stored at one site(Service Provider) with another application without having to store or manage credentials at the Application side.

There are 3 main Actors in an OAuth transaction: the User, the Service Consumer ( which is generally an APP), and the Service Provider. This gang of three are often said to form the OAuth Love Triangle.

Now, assuming that your Game APP implemented OAuth for FaceBook, it can initiate authentication using OAuth.

Below are the steps(and the technical conversation) that will occur at high level among all parties:

1. A user wants Service Consumer (App) to access his protected resource lying with Service Provider (Facebook) :

User: “Hey App, I enjoyed the game but now I would like you to be able to share my game score on my Facebook timeline.”

Game App: “No problem! Let me ask for permission from Facebook. ”

2. The service consumer asks for request token from service provider.

Game App: “My user wants me to post to his wall. Please share a request token.”

Facebook: “Your request is answered. Take the token and associated secret.”

Using the secret, the service provider is able to verify the future requests by consumer (if its coming from the valid Service Consumer).

3. The user is redirected to the service provider where user approve the service consumer to act on his behalf.

Game App: “Hey user, I’m redirecting you to Facebook so you can approve me for the actions you want. Take the token with you which I got from Service Provider(Facebook).”

User: “Ok”

4. The user sees a form presented by the Service provider which lists all the actions the Service Consumer can take on user’s behalf. If user thinks its all OK, he approves.

Facebook: “Welcome User, do you want to authorize the Game App for all the A, B, and C actions?”

User: “Yes, I approve”

Facebook: “OK, the request token is approved for the Game App”

5. The service consumer obtains an access token in lieu of request token from service provider

Game App: “Facebook, Can you provide an access token for this approved request token?”

Facebook: “Sure. Take the access token and secret.”

6. The service consumer preserve the access token and secret information for later use.This information can be saved along with user account with service consumer.

Game App : Hey User, now you can share the score on your wall as long as you keep me authorized with Facebook.

User: Great! But please note I will revoke your permission on my account with Facebook anytime I wish.

7. The service consumer accesses the protected resource (of user) on behalf of user.

Game App: “My user wants to share score on his Facebook wall. Here is the access token for the action”

Facebook: “Your access token looks valid. Your request can be carried on!”

OAuth is adopted by many Service Providers like Facebook, Twitter,Google, Yahoo and all the Consumers that consume the service from them.

The initial version of OAuth is 1.0 which is still being used by some software companies. The second and latest version , OAuth 2.0, is created to simplify development while still providing app authentication and specific authorization flows for web apps, desktop applications, and mobile devices. For OAuth history and deep details, you can go to oauth.net and Wikipedia .

Setting Up Environment Configuration of Windows Phone 8 development

2013-04-14T21:39:00.002-07:00

Hi Readers,

A very common and simple blog today.
"Setting Up Environment Configuration of Windows Phone 8 development"

Your first task when it comes to Windows Phone development is getting your development environment up and running. It’s a three step process:

Install Windows 8

Windows 8 Pro edition or greater is required

Your machine must have a processor that supports Second Level Address Translation (SLAT)

Install Visual Studio Express 2012 for Windows Phone

Web Installer – this is a small initial download that will download the necessary components during the installation process. Download at http://bit.ly/YSPmrh.

Disk Image (iso) – This is the full installer, no additional downloads are required. Download athttp://bit.ly/Tmb6rX.

Optional: Join the Windows Phone Dev Center

You can’t create Windows Phone apps on anything but a 64 bit version of Windows 8. There are two additional requirements for running the Windows Phone 8 emulator:

What this means is that you can’t run a Windows Phone 8 development inside of a virtual machine. This is due to the Hyper-V technology used in the Windows Phone emulator.

For installing Windows 8 you have several options. If you’re running a Windows 7 machine, you can either upgrade your existing install, create a separate partition for you Windows 8 install, or create a bootable vhd with Windows 8 (this is not the same as running inside of a virtual machine).

Download and install Visual Studio Express 2012 for Windows Phone from http://aka.ms/getvs12now. Visual Studio is the IDE, similar to Eclipse, that you’ll use for creating Windows Phone applications. Please note, there are a five Visual Studio Express products available. Make sure you download and install the one specifically for Windows Phone.

There are two options for installation, a web installer and a disk image. A description of each is below, choose the one that works best for you:

If you already have a different edition of Visual Studio Express installed on your machine don’t worry, Visual Studio Express 2012 for Windows Phone will install just fine with it.

After you install Visual Studio you can try it free for up 30 days. After 30 days you must register to obtain a free product key for ongoing use. Just remember, it’s free as long as you register. You can register athttp://bit.ly/URM0I8.

This step is not required to start developing Windows Phone applications. However, if you want to test your apps on Windows Phone hardware and submit your apps to the Windows Phone Store, you must register for a Windows Phone Dev Center account. You can learn more about the Windows Phone Dev Center and register at http://bit.ly/StpJhE.

That’s it! You’re good to go. In the next lesson you’ll learn how to create your first Windows Phone 8 App.

Add Multiple WebParts using PowerShell Script

2013-03-28T21:20:00.001-07:00

Hi All,

Imagine a scenario where you need to create 100 web part pages with different templates. You would spend a lot of time creating those pages. One of the approaches can be having a PowerShell script which can create web part pages for templates that you want.

Here is a simple script that creates web part pages in a loop.

[xml]$xmlfile = Get-Content ConfigFile.xml

foreach( $sitecoll in $xmlfile.Configuration.SiteCollection)

{ $site = $sitecoll.name }

$spSite= Get-SPSite $site

$web = $spSite.OpenWeb()

$layoutTemplate = 4 # Template code

$web = $spSite.OpenWeb()

$list = $web.GetList("/sites/SharePointSite/SitePages/")

$i = 1

while ($i -le 5)

{ Write-Host $pageTitle = "WebPartPage& + $i

$xml = "<?xml version=""1.0"" encoding=""UTF-8""?>

<Method ID=""0,NewWebPage""><SetList Scope=""Request"">" + $list.ID + "</SetList><SetVar Name=""Cmd"">NewWebPage</SetVar><SetVar Name=""ID"">New</SetVar><SetVar Name=""Type"">WebPartPage</SetVar><SetVar Name=""WebPartPageTemplate"">" + $layoutTemplate + "</SetVar><SetVar Name=""Overwrite"">true</SetVar><SetVar Name=""Title"">" + $pageTitle + "</SetVar></Method>"

$result = $web.ProcessBatchData($xml)

$i++

Write-Host -foregroundcolor Green $pageTitle 'created successfully'

}

and when you run here is the output of the script and then final result

If you observe closely here we have specified layouttemplate, we have specified 4. This related to various templates like three column, four columns, headers the template that we select while creating web part page.

Possible LayoutTemplate values are :

# 1 - Full Page, Vertical

# 2 - Header, Footer, 3 Columns

# 3 - Header, Left Column, Body

# 4 - Header, Right Column, Body

# 5 - Header, Footer, 2 Columns, 4 Rows

# 6 - Header, Footer, 4 Columns, Top Row

# 7 - Left Column, Header, Footer, Top Row, 3 Columns

# 8 - Right Column, Header, Footer, Top Row, 3 Columns

WebPart Life Cycle in different PostBacks

2013-02-23T23:19:00.001-08:00

On Page Load

Constructor
OnInit
OnLoad
ConnectionConsumer method is called if web part is connectable (sets the connection providers interface in the webpart)
CreateChildControls
OnPreRender (if your web part is connectable you would typically call the connection provider here to retrieve data)
SaveViewState
Render
RenderChildren
RenderContents

On 1st Postback
(PostBack click handler sets ViewState via public Property)

Constructor
OnInit
CreateChildControls
OnLoad
PostBack click handling
ConnectionConsumer method is called if web part is connectable (sets the connection providers interface in the webpart)
OnPreRender (if your web part is connectable you would typically call the connection provider here to retrieve data)
SaveViewState
Render
RenderChildren
RenderContents

On 2nd Postback
(PostBack click handler sets ViewState via public Property)

Constructor
OnInit
LoadViewState
CreateChildControls
OnLoad
PostBack click handling
ConnectionConsumer method is called if web part is connectable (sets the connection providers interface in the webpart)
OnPreRender (if your web part is connectable you would typically call the connection provider here to retrieve data)
SaveViewState
Render
RenderChildren
RenderContents

Note that during the 2nd postback, LoadViewState, is called, since in the 1st postback the click handler sets the value of the ViewState backed public property.

Where are Assemblies in Sandboxed Solutions Deployed?

2013-02-21T22:59:00.001-08:00

Hi All,

Sometime back I started working on SandBox Solutions. I came across many issues and situation in terms of restrictions and Resource Point Utilization.

When I tried creating a Visual WebPart then I neede PowerTool VS extensions inorder to make it work.
Hence I realized that in sandbox solution, we are not dealing with file system. It its not that way then where my assemblies reside.

Then came across a msdn article which enlightened me with following facts.

The assemblies in the sandboxed solution are included in the solution pkg i.e. ".wsp" file, and the pkg is deployed to the site collection's solution gallery.
When a sandbox solution is accessed for the first time i.e. when a user access the webpart from sandbox solution, any assembly in the solution is extracted from the pkg in the gallary and copied to the file system of the server that is handling the sandboxed request. The location is
c:\ProgramData\Microsoft\SharePoint\UCCache

The executable of this service is SPUCHostService.exe. The server that handles the sandboxed request is not necessarily the front-end web server that is handling the initial HTTP request.
The Microsoft SharePoint Foundation Sandboxed Code Service can be run on back-end application servers in the farm instead. Because the sandboxed user process (SPUCWorkerProcess.exe) cannot copy anything to the file system, the copying is done by theMicrosoft SharePoint Foundation Sandboxed Code Service.

The assemblies of a sandboxed solution do not stay in the file cache perpetually. When the user session that accessed the solution ends, the assemblies stay in the cache for only a short time, and they may be reloaded from there if another user session accesses them. Eventually, if they are not accessed, they are removed in accordance with a proprietary algorithm that takes into account how busy the server is and how much time has gone by since the assemblies were last accessed. If the sandboxed solution is used after that time, the assemblies are extracted again and copied to the UCCache.

How to create a Dynamic CAML Query

2013-01-19T00:05:00.001-08:00

Hi All,

Many a times you might come into a situation when you have to deal with some complex query building and the scenario is like you have to pull the data from a SharePoint list and the records on which you need to fire the <Where> clause is not fixed.

So, you to need to write a dynamic query where the <OR> tags changes accordingly.

Here is the code:

// This lstPeers can be of any type like array or List Type or Collection.
List<String> lstPeers = new List<String>();

SPQuery peersQuery = new SPQuery();
string createquery = "";

peersQuery.Query = "<Where>" + CreateDynamicQuery(createquery, lstPeers) + "</Where>";

Here is your Dynamic Query :

protected String CreateDynamicQuery(String query, List<string> lstString)
        {
            bool firstIteration = true;
            if (query != "")
            {
                query = "<Or>" + query;
                firstIteration = false;
            }

            if (lstString.Count >= 2)
            {
                query += "<Or>";
                query += "<Eq><FieldRef Name='Type' /><Value Type='Lookup'>" + lstString[0] + "</Value></Eq>";
                query += "<Eq><FieldRef Name='Type' /><Value Type='Lookup'>" + lstString[1] + "</Value></Eq>";
                query += "</Or>";

                lstString.RemoveRange(1, 1);
                lstString.RemoveRange(0, 1);

                if (!firstIteration)
                    query += "</Or>";

                if (lstString.Count != 0)
                    query = CreateDynamicQuery(query, lstString);
            }
            else
            {
                if (lstString.Count != 0)
                {
                    query += "<Eq><FieldRef Name='Type' /><Value Type='Lookup'>" + lstString[0] + "</Value></Eq>";
                    if (!firstIteration)
                        query += "</Or>";
                }
            }
            return query;
        }

As you can notice you are calling a recursive function and dynamically creating the <OR> tags.

I am sure this will help your case !!

Error occurred in deployment step 'Recycle IIS Application Pool': The communication object, System.ServiceModel.InstanceContext, cannot be used for communication

2013-01-10T23:14:00.002-08:00

Hi All,

When deploying a solution to SharePoint 2010, I suddenly got the error message:

Error occurred in deployment step ‘Recycle IIS Application Pool’: The communication object, System.ServiceModel.InstanceContext, cannot be used for communication because it has been Aborted.

Restarting Visual Studio did the trick. (IISreset did not help..)

SharePoint 2010 Web Part Error "The UserCodeToken is invalid"

2013-01-09T22:42:00.002-08:00

Hi All,

The error says "Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: The UserCodeToken is invalid". While this error message is very descriptive, it wasn't very helpful in determining a solution. No events in the error

Update: Sandboxed solutions not working, try restarting the service in powershell "Restart-Service SPUsercodeV4"

Populate Drop Down Lists in Client Object Model

2013-01-07T03:06:00.001-08:00

Hi All,

SharePoint 2010 provided two major custom web part enhancements: Visual Web Parts and Client Side Object Model (COM) using JavaScript. We can populate a dropdown items from a sharepoint list.

First populate a list for example : InterviewerList

In visual webpart add following tag in .ascx file inside a DIV tag :

</select>

Then jump to your .js file and write following code :

jQuery(document).ready(function () {

ExecuteOrDelayUntilScriptLoaded(function () {
obj = new ScheduleInterviewClass();
obj.LoadObjects();
}, "sp.js");
});

function ScheduleInterviewClass() {

this.LoadObjects = LoadObjects;

var siteObjects = {
ctx: null,
web: null,
url: null,
InterviewerList: null,
InterviewerListItems: null
};

function LoadObjects() {
siteObjects.ctx = SP.ClientContext.get_current();
siteObjects.web = siteObjects.ctx.get_web();
siteObjects.ctx.load(siteObjects.web);
siteObjects.ctx.executeQueryAsync(Function.createDelegate(this, LoadObjectsOnSuccess), Function.createDelegate(this, LoadObjectsOnFailure));
}

function LoadObjectsOnSuccess() {

siteObjects.InterviewerList = siteObjects.web.get_lists().getByTitle("InterviewerList");
var query = new SP.CamlQuery();
query.set_viewXml();

siteObjects.InterviewerListItems = siteObjects.InterviewerList.getItems(query);

siteObjects.ctx.load(siteObjects.InterviewerListItems);
siteObjects.ctx.executeQueryAsync(Function.createDelegate(null, RenderHtmlOnSuccess), Function.createDelegate(null, RenderHtmlOnFailure));
}

function LoadObjectsOnFailure() {
alert("Objects Not Loaded Properly. Try again");
}

function RenderHtmlOnSuccess() {
var ddlInterviewer = this.document.getElementById("ddlInterviewerName");
ddlInterviewer.options.length = 0;
var enumerator = siteObjects.InterviewerListItems.getEnumerator();

while (enumerator.moveNext()) {
var currentItem = enumerator.get_current();
ddlInterviewer.options[ddlInterviewer.options.length] = new Option(currentItem.get_item("InterviewerName").get_lookupValue(), currentItem.get_item("ID"));
}
}

function RenderHtmlOnFailure(sender, args) {
alert(args.get_message());
alert("Not able to render HTML");
}

}

How To Add Custom Web Part Properties To Visual Web Part In SharePoint 2010

2013-01-06T21:12:00.000-08:00

Hey Folks,

Let’s see how we can add custom web part properties to a visual web part in SharePoint 2010.

Open Visual Studio 2010 -> File -> New -> Project -> Visual C# -> SharePoint -> 2010 and select Visual Web Part project template as below:

In SharePoint Customization Wizard, validate the SharePoint 2010 site URL as below:

Once Visual Studio 2010 open ups, it will look like below:

Open VisualWebPart1.cs file and add below code:

namespace AddCustomProperty.VisualWebPart1
{
[ToolboxItemAttribute(false)]
public class VisualWebPart1 : WebPart
{
// Visual Studio might automatically update this path when you change the Visual Web Part project item.
private const string _ascxPath = @”~/_CONTROLTEMPLATES/AddCustomProperty/VisualWebPart1/VisualWebPart1UserControl.ascx”;

private string _Name;
[WebBrowsable(true), WebDisplayName("Name"), WebDescription("My Name"),
Personalizable(PersonalizationScope.Shared), Category("Custom Property"),
System.ComponentModel.DefaultValue("")]

public string Name
{
get { return _Name; }
set { _Name = value; }
}

protected override void CreateChildControls()
{
VisualWebPart1UserControl control = (VisualWebPart1UserControl)Page.LoadControl(_ascxPath);
control.Name = Name;
Controls.Add(control);
}
}
}

It should look like below:

Open VisualWebPart1UserControl.ascx file and add below code:

It should look like below:

Open VisualWebPart1UserControl.ascx.cs file and add below code:


namespace AddCustomProperty.VisualWebPart1
{
public partial class VisualWebPart1UserControl : UserControl
{
public string Name { get; set; }

protected void Page_Load(object sender, EventArgs e)
{
NameLiteral.Text = "Your Name is : " + this.Name;
}
}
}

It should look like below:

Deploy The Project:

Thanks & Have Fun!!

What is an App in SharePoint 2013

2013-01-06T20:50:00.001-08:00

App is similar to a web part. One main key difference is everything is at the client side and not on the server side when you write a code developing an app which is called client web part.

In SharePoint 2013 Lists and Libraries are now termed as apps.

SharePoint now has its own app store where we get some free apps and some paid apps which can be installed and then can be used inside SharePoint.

There are three hosting options when you create app for SharePoint.

1) SharePoint hosted - On Premises.

2) Externally hosted

3) SharePoint Online - Sandbox solutions can be created. (deprecated now in SharePoint 2013) or new apps web part (client web part) can be used.

Certain important points about an app are :

App cannot have any server side code.

Apps get created in a special “app web” on a special URL which is isolated from the original SharePoint web. Each app is a part of dedicated site collection.

App does not have permission to talk to the parent site or site collection

App cannot talk to the host site. ( a site in which app is displayed)

Apps can be created using Visual Studio 2012 or using "Napa" Office 365 Development Tools

So SharePoint 2013 apps do not live in SharePoint rather they execute within the browser client or in a non-SharePoint server such as IIS or Windows Azure.

Apps can only be added by users with Full Control permission to the site. As mentioned earlier Apps can be installed from the centralized app store from on premises SharePoint or from public app store.

Apps can also be opened as a full browser screen or can also be a part of page. When we want app as a part of page we can use app part just like a web part to display that app in the app part. App part will display content of that app part in Iframe html element.

Regardless of how you authenticate your app with SharePoint, you need to have user consent to perform actions. You declare the required permissions in the app manifest file while developing, and the user is asked to grant or deny those permissions to the app during installation.

You can connect your app with just about any internal or public web services, take advantage of the new OAuth 2.0 support in SharePoint, and use the Representational State Transfer (REST) and client APIs (JavaScript and .NET) to integrate and connect your app with SharePoint.

There is a list of available apps that can be downloaded (some free / some paid versions) from Microsoft market place for SharePoint 2013.

Microsoft App Market place for SharePoint 2013

FBA Cookie getting expired only in Safari and Chrome.

2012-12-25T22:26:00.002-08:00

Hi Reader,

This blog is for all those guys who have tried their level best to solve this unique issue and still couldnt get the root cause why the Form Based Authentication Cookie getting expired daily ( almost after some hours ) ONLY on Safari and Chrome browser.

I have spend lot many days finding the root cause of this issue and yes also solve it for clients.
Applicaiton that use hosted Safari inside of UIWebView ( which is also Chrome) or Apps that host a website in PhoneGap usually face this issue. If its FBA then Google Chrome for iOS might switch FormsAuth to Cookieless mode.

This has been fixed in .NET 4.5 and you wont see this issue if you have .NET 4.5 installed, even uf you're running .NET 4 application. Since now you are facing this trouble then here are following steps to follow and immediately get rid of this issue.

Thanks to blogger: Scott

STEP 1: Modify your web.config file.

<authentication mode="Forms" >
  <forms loginUrl="~/Account/SignIn" timeout="2880" cookieless="UseCookies" />
</authentication>

STEP 2: Once you explore your Sharepoint hosted site in IIS you will notice the app_browser folder.
Create a "generic.browser" named file in that folder and paste the exact code in it.


<browsers>

  <browser refID="GenericDownlevel"> 

    <capabilities> 

      <capability name="cookies" value="true" /> 

    </capabilities>

  </browser>

</browsers>

STEP 3: Generate a New MachineKey.

“Machine key a unique key that differentiates one computer from others. And this key is used to create unique identifier when cookie is created in the client machine from a server side code. This key is generally present in the machine.config file when you install .NET framework that is generally not visible to the user as it remains in the .NET Framework installation directory. When you specify the same key in your web.config, the value of machine key specified in the machine.config is overridden by the one you have specified in the web.config file. “

Once the key is generated, they are converted into a string of hexadecimal characters.

Created a 256-bit decryption key and a 512-bit validation key, with Rijndael as the data validation algorithm.

You need to include this newly created machine key in your web.config file.

Generate Machine Key

Hope my above solution will surely save lot of efforts and time.

How to extract metadata or details of a DLL IN GAC using Powershell

2012-11-28T02:07:00.000-08:00

Hi,
Recently I came across an issue to fetch the details of the DLL in GAC Folder.
Detail are like, Name , Version Number and TimeStamp using powershell.

I searched a lot in google and blogs and also in MSDN but didnt found any fruitful result.
Finally after too much to working on this I finally came up with a simple solution.

Here is the script:

set-variable -option constant -name out -value "dllInventory.csv"
"Name, Version, Time" | Out-File $out -Append

Foreach( $file in Get-ChildItem C:\windows\assembly -Recurse -filter "*.dll" )
{
if ($file -match "(.*dll)$")
{

#$temp = $file.Name, $file.VersionInfo.FileVersion, $file.lastwritetime
$file.Name + ", " + $file.VersionInfo.FileVersion + ", " + $file.lastwritetime | Out-File $out -append
}
else
{write-host "Not Found"}
}
}
Hope this is help !!

Iterate in Resource File and fetch value of the matching String

2012-11-23T20:35:00.001-08:00

Hi Reader,

Recently I came across a requirement where I need to iterate in a resource file added in my ASP.NET Project and fetch the matching value of a specific string.
Exact requirement goes like this, I have to return a Token Key ( Value ) of a Domain Name ( String Name) in a resx file. If the URL contains the Domain Name which is added in resx file then respective Token Key is fetched.
So we need to loop in the resx file, look for the containing string and if it matches then returns the value.
Code goes like this :

ResourceManager resourceManager = new ResourceManager("Resources.SiteUrl", System.Reflection.Assembly.Load("App_GlobalResources"));
                        
                        ResourceSet resourceSet = resourceManager.GetResourceSet(CultureInfo.CurrentUICulture, true, true);
                        foreach (DictionaryEntry entry in resourceSet)
                        {
                            object resourceKey = entry.Key;
                            object resource = entry.Value;
                            if (returnUrl.Contains(resourceKey.ToString()))
                            {
                                DomainName = resourceKey.ToString();
                                Token = resource.ToString();
                            }
                        }
                        if (DomainName != null)
                        {
                            if (returnUrl.Contains(DomainName))
                            {
                                returnUrl = string.Format("{0}/_layouts/Authenticate.aspx?{1}={2}", returnUrl, Token, authCookie);
                            }
                        }

In Above code , ResourceManager Object is created to that looks up resources contained in files with the specified root name in the given assembly.
ResourceSet Stores all the resources localized for one particular culture, ignoring all other cultures, including any fallback rules.

DictonaryEntry will get the key value pair of each item in the resource file.

Hope this helps !!

How to Remove Site Template from Custom Tab

2012-11-10T12:04:00.001-08:00

Hi All,

I have created test site template with name MyTestTemplate and MyTestTemplate2. Since this site is used by many developers and designers.
Later I found that in the Solution Galllary does not have any such solution with name MyTestTemplate and MyTestTemplate2 but it was still showing in Custom TAB of Site Template.

After those templates were deleted in the Solutions Gallery, they were still listed in the Custom group of new site templates, and could still be used - maybe because they were still available in the Recycle Bin.

To hide them from the Create Site options, I restored them from the Recycle Bin, then chose Deactivate from each item's drop-down menu, and then deleted them again. That solved the problem.

HOW TO ADD A CALENDAR LIST VIEW WEB PART TO ONET.XML

2012-11-09T23:09:00.000-08:00

Hi All,

My requirement was to add a calendar in a provisioned page so I found there is a way to set web part properties inside a CDATA section of the view. The Views are generated from the Microsoft.SharePoint.WebPartPages.ListViewWebPart.

I hope this code will help your requirements as well.

<View List="Lists/PluginCalendar" BaseViewID="2" Type="CALENDAR"
       Scope="Recursive" RecurrenceRowset="TRUE" WebPartZoneID="TopWebZone"
       WebPartOrder="0">
       <![CDATA[
         <WebPart xmlns="http://schemas.microsoft.com/WebPart/v2">
             <Assembly>Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral,
                       PublicKeyToken=71e9bce111e9429c</Assembly>
             <TypeName>Microsoft.SharePoint.WebPartPages.ListViewWebPart
                       </TypeName>
             <Title>Calendar of Events</Title>
             <FrameType>None</FrameType>
         </WebPart>
       ]]>
 </View>

Cannot recognize the XML namespace of this Web Part

2012-11-09T23:02:00.003-08:00

Hi All,

When provisioning pages (e.g. default.aspx) using a feature, you can add default webparts using <AllUsersWebPart>

Keep in mind you have two types of webparts, v2 en v3. When provisioning v2: you should use the following syntax:

<AllUsersWebPart WebPartZoneID="FooterLeft" WebPartOrder="2">                
<![CDATA[                             
<WebPart xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.microsoft.com/WebPart/v2">                  
...
</WebPart>                
]]>            
</AllUsersWebPart>

and with v3:

<AllUsersWebPart WebPartZoneID="FooterLeft" WebPartOrder="5">                
<![CDATA[                    
<webParts>                      
<webPart xmlns="http://schemas.microsoft.com/WebPart/v3">   ... 
</webPart>                    
</webParts>                
]]>            
</AllUsersWebPart>
Look at the difference in attributes of WebPart-tag AND the extra <webParts> tag in the v3-version. If you add <webParts> around the <webPart>-declaration in the v2-version, you could receive the error: Cannot recognize the XML namespace of this Web Part.

How to Detach SQL Database if DB is in Single User Mode

2012-10-23T04:46:00.003-07:00

Hi Readers,

I came across a scenario where I need to detach the SQL Database and then take backup of .ldf and .mdf files.
Copy is not possible unless we do not detach the DB. This single user mode is set by SQL Server inorder to prevent corruption of database tables.

You can set the database back to online mode or say multi user mode by executing following commands.

exec sp_dboption 'your db name', 'single user', 'FALSE'

If error still persists, then you need to check which your is having connection with the database and find the particular spid

Inorder to find the connected users execute following command.

select d.name, d.dbid, spid, login_time, nt_domain, nt_username, loginame from sysprocesses p inner join sysdatabases d on p.dbid = d.dbid where d.name = 'your db name'

This will fetch the users with their $spid. Kill the spids you see using following command.

Kill <spid> : Here <spid> will be some numeric id like 125, so write Kill 125

again run the 1st command and you will be back to Multi User Mode.

Hi Readers,

This is the first time I dealt with SP Migration from MOSS 2007 to SharePoint 2010 and have faced lot of issues while working. As per my experience and knowledge, I suggest 10 important points to remember and the difficulties you face while dealing with SP Migration.

1.To Upgrade, or to Migrate ??
2. Migrating Data
3. Migrating from Older Versions of SharePoint
4. Dealing with an Oversized Content Database
5. Wrong Site Template or Site Definition
6. Dealing with Unwanted Data
7. Migrating Content Types
8. Populating Metadata
9. Migrating Files from Outside SharePoint
10. Migrating Data from Exchange Public Folders.

Set the Custom 404 Error Page

2012-10-17T06:13:00.001-07:00

Hi,

Have you ever tried setting up the Custom Error Page in SharePoint 2010. For long time I was aware of only below such ways of setting up the Custom Error Page.

1.) Modify the web.cofig file and set the <customErrors> = "ON".

2.) Either you can set it from IIS.

3.) Programmatically set the custom 404 page.

Ref : http://leonidius2010.wordpress.com/2011/06/08/sharepoint-2010-adding-custom-error-page/

But a another way is a much smarter way i.e. To configure SharePoint Foundation server or SharePoint Server 2010 to point to a custom 404 error Web page via File System.

Log on to the computer that is running SharePoint Server 2010 by using an account that has administrative permissions.
In Windows Explorer, locate the following folder:
c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\LangID
Create the custom HTML file:
1. On the computer that is running SharePoint Server 2010, copy the Sps404.html file to a temporary folder.
2. Rename the Sps404.html file. For example, give the file the following name:
  Custom404.html
3. Modify the Custom404.html file to suit your needs for a custom 404 error message using an HTML editor.
Note : In sps404.html you will notice STSNavigate("/_layouts/spsredirect.aspx?oldUrl=" + requestedUrl). You need to modify the line as per you requirement , either create another .aspx page and save it in _layouts folder or can directly point to any .aspx file located on the sharepoint library. i.e. STSNavigate("http://www.mytestsite.com/about/pages/404notfound.aspx");

4. Copy the Custom404.html file to the %systemdrive% \Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\LangID folder.

Run the following PowerShell commands from the SharePoint 2010 Management Shell:

$webapp =Get-SPWebApplication http://<serverUrl>:<port>

$webapp.FileNotFoundPage = "Custom404.html"

$webapp.update()

How to get Public key token in Visual Studio 2010

2012-10-17T02:35:00.001-07:00

I was developing a custom application for SharePoint and needed to assign it with strong name I assigned a strong name to my project. Now was the time to see the token generated for it. I went ahead and tried to drag that assembly to GAC but I got access denied.

Development machine is Windows Server 2008. Now I tried installing it using GACUTIL but I got the same result even being the administrator of the machine.

Challenge comes in when you want to know the public key token that has been generated for the project so that you can make modification in web.config file.

So here is a solution. We will create an external command that will get us the public key token of the project. So that when that command is clicked we get to see result in command window.

Follow these simple steps. Make sure about spacing and parameters shown here.

Go to Tools menu and then external tools.

Click Add button on which the dialog opens.

Set textbox values like this

Command text box value is

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\sn.exe

Click on OK.

Now when you again click on Tools menu, you get to see our command.

Click on it and we will get the result in output window and from there you get to know the public key token.

I hope this will help while you are developing any custom component in SharePoint.
