Making PDF open in same Browser(Sharepoint)

2012-07-26T14:06:4705:30:00

By default Sharepoint will not open pdf file in browser, rather it will force the user to save the pdf file and open. This is becuase pdf file by default is not a supported mime type.

You can change the setting for a specific web application using the following powershell.

$webapp = Get-SPWebApplication -Identity YOU_WEB_APPLICATION_URL
$webapp.AllowedInlineDownloadedMimeTypes.Add("application/pdf")
$webapp.Update()

Configuration Data in a Custom Timer job in SharePoint 2010 : The Hierarchical Object Store

2012-04-05T23:01:4805:30:00

I was planning for a custom timer job for which i wanted to store some configuration data. Was looking for some best practices, found a useful links on The Hierarchical Object store Store http://www.chaholl.com/archive/2011/01/30/the-skinny-on-sppersistedobject-and-the-hierarchical-object-store-in.aspx

Initially was planning for a custom list, but this would make us run a cross site query and the list name and the url should again be kept in some configuration which is an headache to maintain. Hierarchical object store was zeroed in and thanks to Google for the same :)

A Console Application or Windows Application in VS 2010 for Sharepoint 2010 : A common Error

2012-03-22T13:41:5005:30:00

I have seen many Sharepoint Newbies cracking their head to create a Console/Windows application in VS2010 and make it talk to Sharepoint 2010 Server. I had the same problem when i started with Sharepoint in the begining.

It is important for you to acknowledge that SharePoint 2010 is based on .NET Framework version 3.5 and not version 4.0.

In VS 2010 when you create a Console/Windows application, Make Sure you select .Net Framework 3.5 in the New Project Dialog Window.If you have missed while creating new Project Go to the Application tab of project properties and verify that .NET Framework Version 3.5 is select as the Target Framework.

Now that you have selected the correct framework, will it work? Nope if the application is configured as x86 one it will not work. Sharepoint is a 64 Bit application and when you create a windows application to talk to Sharepoint it should also be a 64 Bit one. Go to Configuration Manager, Select x64. If x64 is not available select <New…> and in the New Solution Platform dialog box select x64 as the new platform copying settings from x86 and checking the Create new project platforms check box.

This is not applicable if you are making a console application to talk to sharepoint with Client Object Model.

Gettings Terms asscoiated to a Specific list item

2012-03-22T13:16:0305:30:00

I had a fancy requirement where i had to get all tags associated to a document set in a document library. The normal tag could webpart was not working when i add it to the document set home page, so planned a custom webpart.

Was checking in net to find a straight forward way to achieve this, but was not lucky enough to get something. Since i didnt get any samples in net, i looked into Microsoft.Sharerpoint.Portal.Webcontrols and found a solution.The socialdataframemanager control in 14Hive/Template/layouts/SocialDataFrame.aspx directed me to the solution. You can get the dll from ISAPI folder. Following Code snippet can get all Terms associated to the List Item given that you have list name and id for the list item.

using System;

using

System.Collections.Generic;

using

System.Linq;

using

System.Text;

using

Microsoft.SharePoint;

using

Microsoft.Office.Server.SocialData;

namespace

TagChecker

{

class Program

{

static void Main(string[] args)

{

// Your site url

string siteUrl = http://contoso;

// List Name

string listName = "DocumentLibrary1";

// List Item Id for which you want to get all terms

int listItemId = 35;

using (SPSite site = new SPSite(siteUrl))

{

using(SPWeb web = site.OpenWeb())

{

SPListItem listItem = web.Lists[listName].GetItemById(listItemId);

string url = string.Empty;

// Based on the list type the url would be formed. Code Sniffed from Micosoft dlls :)

if (listItem.ParentList.BaseType == SPBaseType.DocumentLibrary)

{

url = listItem.Web.Url.TrimEnd(

new char[] { '/' }) + "/" + listItem.Url.TrimStart(new char[] { '/' });

}

else if (SPFileSystemObjectType.Folder == listItem.FileSystemObjectType)

{

url = listItem.Web.Url.TrimEnd(

new char[] { '/' }) + "/" + listItem.Folder.Url.TrimStart(new char[] { '/' });

}

else

{

url = listItem.Web.Url.TrimEnd(

new char[] { '/' }) + "/" + listItem.ParentList.Forms[PAGETYPE.PAGE_DISPLAYFORM].Url.TrimStart(new char[] { '/' }) + "?ID=" + listItem.ID.ToString();

}

SPServiceContext serviceContext = SPServiceContext.GetContext(site);

Uri uri = new Uri(url);

SocialTagManager mgr = new SocialTagManager(serviceContext);

SocialTerm[] terms = mgr.GetTerms(uri);

foreach (SocialTerm term in terms)

{

Console.WriteLine(term.Term.Labels[0].Value );

}

Console.Read();

}

Reference dlls added are Microsoft.Sharepoint , Microsoft.Sharepoint.Taxonomy, Microsoft.office.server, Microsoft.Office.Server.UserProfiles from ISAPI folder.

This logic can be used to make a custom tag cloud webpart by taking code from OOB tag cloud, so taht you can have you webpart anywhere in the site and still get Tags added to a specifc libdary/List.

Hope this helps some one.

Attempted to perform an unauthorized operation – Error while updating other user’s profile data in Sharepoint 2010

2011-12-14T16:05:4605:30:00

We had a requirement where a user profile property will be updated from the event receiver of a custom list. The user profile property which we can had “user can override” and “Allow users to edit”, however we were getting an error “Attempted to perform an unauthorized operation”

The code was running under RunWithElevated delegate. We traced the user id which was Sharepoint\System. The system account in use will be the App pool Identity under which the current Sharepoint site is running. We took app pool identity id and gave full permission for user profile service application. This didn’t solve our problem.

Solution:

Get the App pool identity, of the Sharepoint site from IIS.

Go to Sharepoint Central Admin > Application Management > Manage Service Application.

Select the User Profile Service Application which is associated to your site, and select Manage Permission from top ribbon. Add the App Pool Id and give full control.

Then select Administrators in the TOP ribbon for User Profile service application and add the app pool identity id and give full control.

Block Application pages and Form Pages in Sharepoint 2010

2011-11-03T13:56:2705:30:00

By default Sharepoint doesn’t blocks user with limited access from visiting application pages (for ex _layouts/viewlsts.aspx).

Someone who knows the URL, can go to this page.

We can avoid this by change the limited access to lockdown mode. Use the command below.

Action	Command
Turn on lockdown mode for a site collection	stsadm -o activatefeature -url <site collection url> -filename ViewFormPagesLockDown\feature.xml
Turn off lockdown mode for a site collection	stsadm -o deactivatefeature -url <site collection url> -filename ViewFormPagesLockDown\feature.xml

For more info on this visit http://technet.microsoft.com/en-us/library/cc263468(office.12).aspx#section6

Once locked down mode is enabled, groups/users with View Application pages will only be able to visit these pages. You can either select Restricted Read permission or remove View Application Pages permission for the users or groups which you want to block application pages.
