Recently I was working on a project that requires to programmatically access and download files from SharePoint Online (part of Office 365) document library. Currently remote authentication (SP Managed Client OM / SP Web Services) is bit challenging to deal with as discussed here but a decent workaround (for now?) is available on MSDN. The first thing you will notice is that authentication is more powerful and more complex because SharePoint Online (so as SharePoint Foundation 2010 | SharePoint Server 2010) embrace Claims Based Authentication. The MSDN sample code seems to work fine so I went ahead and use it as a starting point.
**I used Word 2010 to create and publish this post and somehow images quality gets deteriorated during publishing process. If you want to read this post with high quality images its available as pdf here
Everything went smooth (authentication + accessing list items) till I actually try to download a file from a document library. I was using File.OpenBinraryDirect method (see code snippet below) and got The remote server returned an error: (403) Forbidden exception.
As I investigate this issue by looking into the exception details I found out that basically it’s complaining about the fact that before opening files in this location I must select the option to login automatically.
This gives me the clue that there is something missing at a basic level. I went ahead and open up a browser and browse to the SharePoint online site from which I am trying to download the file. I use a tool to monitor the request from the browser and eureka I see User-Agent header with a valid value (as expected) which was never set in the code.
The code from the MSDN does not set the UserAgent property of the WebRequest so it remains null. Normally when you are using browser it’s automatically set up for you but in this case you have to do it yourself though code. So you fix this part and you are good to go.
Locate the method GetAuthenticatedContext (inside class ClaimsClientContext within ClaimsAuth project). And add following line of code before you initialize cookie container. You are setting up UserAgent property for the WebRequest to a valid user agent. I have used following value for user agent but you can try different but valid value and it may work too (but I didn’t tried it yet).
e.WebRequestExecutor.WebRequest.UserAgent = “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)”;
That’s it! You should now able to download the files without any issues.
**On a side note although above solutions works I have a feeling that there is more to it because X-MSDAVEST_Error: 917656 is an Authentication level error and related to WebDav protocol more info here. I may investigate it further when time permits and share my finding in this blog post.
As Office 365 goes into public beta, it’s time to dig deeper into the features of Office 365. I am conducing a session on Office 365 with demo of its services @ Microsoft NYC on 27th April 2010 from 6:00 PM – 8:00 PM. Registration is free (if you don’t like to register via website and still want to attend, arrive bit early so you can be registered onsite). I am planning to cover following topics
- Office 365 Overview
Office 365 Walkthrough (Demo)
- SharePoint Online
- Exchange Online
- Lync Online
- Office Web Applications
- Case Study & QA
As a good gesture of good will every attendee will receive a free copy of Enhanced Productivity with SharePoint Online & Exchange Online, a case study I wrote which explains how organizations can leverage Office 365 to enhance their productivity.
Office 365 finally goes into public beta today! Many congrats to Office 365 team J
Visit www.office365.com and apply now to secure your spot in beta program. I was working with Office 365 since last November, just after it was launched as a private beta and it’s been an awesome experience. Things like support service quality and overall stability of services were among the key highlights of private beta and I am quite positive it will remain the same way throughout the life cycle of Office 365.
I have done my own share of work on Office 365. I was involved in a POC of Office 365 and just finished a week back and now planning to help other organizations to adopt Office 365. As a matter of fact I recently wrote an article for MSDN MVP blog focusing on how organization can utilize SharePoint Online and Exchange Online to gain better productivity, article is suppose to be publish soon. I will share the link as soon as it goes live.
If you just started on Office 365 and looking for helpful content read my earlier blog post here.
SharePoint 2010 (both Online & On-Premise) is equipped with new type of Library called Asset Library. Asset library provides place to store your and manage your digital assets and provide enrich interface to view them, another powerful feature is to perform navigation and filtering based on meta data This post demonstrates how to create an asset library, inspect ways how it represents digital items visually, and then how to enable navigation and filtering based on meta data. In order to perform following steps, you must have access to SharePoint 2010 along with at least single SharePoint site collection available to you. One of the easiest ways to start working on SharePoint 2010 is to download Information Worker Demonstration and Evaluation Virtual Machine (RTM) (beware of download size which is couple of GB’s)
Navigate to SharePoint site and click Site Actions à View All Site Content. On the All Site Content Page click Create
Select Asset Library, from the Installed Template and name it My Assets. Click Create.
This is shown in figure below. Note that, if you don’t have Silverlight 3.0 installed on your machine you will see a different page to create various Lists and Libraries, from there you can select Asset Library.
Click Add new item link and select, on the Upload Document dialog click Upload Multiple Files link as show in figure below and upload three images. You can simply drag and drop files. It’s preferred that you choose images with small sizes for example less than 1 MB.
Once the upload process is complete you should see similar view as shown in following figure. Off course your images will be different. Now hover your mouse over an image and you will see that image in a larger dialog box, with more details, this is shown in figure below.
If you want to see the image in a full window, just click View Item link, the image will be open in full view but use the same browser window. To void this and open the image in new tab press CTRL key and then click View Item link, this will make IE 7 or above open the item in separate tab. This is shown in figure below.
Using the same steps as mentioned in step 3 add at least single video and audio file to My Assets Library. The Asset Library supports WMV, WMA and MP3 format for video and audio. If you try to upload other formats you will receive warning as shown in figure below and file(s) will not be uploaded.
Notice that for audio and video thumbnails shows different icons , as shown in figure below.
Hover you mouse on a video or an audio file and you will see the dialog similar to one that appears for image. Following figure shows the dialog for a video file. Notice you have link with title Play.
Click on the Play link, you will see a video player as shown in figure below. The video will start playing automatically. This video player uses Silverlight and it must be installed locally on your machine.
Modifying The Default View
If you notice, the information dialog you get when you hover on any file in step 4 and 7 the dialog lacks two key attributes, file type and file size. This is especially important as media files are usually available is various formats and you may want to know the size and type of the file before downloading it.
To modify the view, click on the Library Tab and select Modify View from Manage View groups. This is shown in figure below.
On the Edit View Page, select the Display checkbox for File Size and File Type (File extension) columns as shown below. Click OK to save your changes.
From the Asset Library, hover on any file and you will see File Size and File Type information inside the dialog, following figure shows this for a video and image file.
Meta Data Driven navigation
Let’s take look into another interesting feature of doing navigation on your digital assets based on Meta data. Imagine your Asset Library with several hundred items or even more, finding anything even when you put them into folders will be daunting tasks. With SharePoint 2010 Meta data driven navigation, the filtering will be done based on Meta data tags, but as Meta data can be hierarchical the navigation is natural and provide users most intuitive way seek the items. However this should never be considered as a replacement of doing categorization by using folders. Also note that meta data driven navigation can be applied to other type of libraries and lists too, event to custom lists!
Let’s enable the meta data driven navigation on My Assets library that you created earlier. From the Library Tab, select Library Settings located in Settings group , as shown in figure below
On Document Library Settings page, select Meta data navigation settings link located under the General Settings section as shown in figure below.
Navigation Hierarchies section, select Content Type from Available Hierarchy Fields list box as shown in figure below.
Click Add > button, this will move the Content Type field to Select Hierarchy Fields list box, as shown in figure below.
On the Configure Key Filters section, select Content Type and Date Picture Taken fields from the Available Key Filter Fields as shown in figure below (If you want you can choose other fields but for this tip these two will be sufficient)
Click the Add> button, both of these fields will be moved to Selected key Filter Fields, as shown in figure below. Finally click OK to save your changes.
Browse to the My Asset library, notice a hierarchical menu on the quick launch as shown in figure below, this enables you to perform navigation on items based on fields in the content type.
Expand the Content Type node by clicking on the small arrow as sown below.
Now click on any of the value, for example Image. Notice when you make this selection, the view on the right is filtered based on this value, following two figures shows the view when selection is done for the values of Image and Video respectively.
Finally lets quickly take a look at Key filtering option present just underneath the navigation we seen earlier, this is shown in figure below.
From the Content Type drop down select Image and from Date Picture
Taken calendar select date when one of the images were originally take (note that your uploaded date and picture taken date will differ). Both of these selections are shown in figure below. Finally click on Apply button. The library view will filter any images that are not taken on the date you had specified.
To sum up Asset Library is an excellent way to store your digit assets including images, audio and videos. Combine with other powerful collaboration and content management features of SharePoint 2010 you can now use SharePoint in your organization in much more productive ways than ever before.

Learning (Conferences + Trainings + Events)
[Update 15th April 2011:- This event is re-scheduled to take place on 1st June 2011]
It’s been really a busy year for me so far, I really like indulging into speaking especially when it comes to user groups and communities. GITCA (The Global IT Community Association) on June 1st 2011 will be conducting a 24 hour virtual event “24 hours in the Cloud” focusing on cloud computing. There will be various sessions ranging from Windows Azure to Office 365 (vNext of BPOS). As Office 365 is currently in private beta it’s a great opportunity for many of you to get a closer look into what’s coming up in next from Microsoft.
I am also presenting in this event, my session is “Office 365 – SharePoint Online Overview”. I will be covering the basics of SharePoint Online and dividing my allocated sixty minutes session time into multiple demos with discussion on various features and functionalities of SharePoint Online. I will also touch base on key considerations while making a shift from On-Premise to Online version of SharePoint. It’s a virtual event and all the speakers including me will be available via twitter (mine is @razibinrais) to answer your questions. I will be sharing my session resources (slide deck + session video) after the session right here on this blog post, so stay tuned for that.
So join in and learn about Microsoft Cloud!
