Dear Sir,
I wanna to do MCP. Pls guide me and some give me study material.
Ton of thanks in advance.
Hi Deepak,
You will get as MCP certificate if you cleared any of the Microsoft Paper. Like I have cleared MCTS 70-536 and 528 . I cleared 528 first . So that time I have got the MCP too. So first of all you have to know which paper you want to give. You want to do it for Web Application or Windows Application .

Hi
Abhijit
My self RAQUIB working in Adecco as Software Developer. I read yor Article from CodeProject regarding IIS and debugging Its really very nice and helpfull.
I have one problem regarding ViewState.
I want to disable view state of server control. I tried to do it by EnableViewState=flase on page or in contol but it retains their values after postback.
I also tried it on OnInit event
private void Page_Init(object sender, System.EventArgs e)
{
this.EnableViewState = false;
}
it also not work.
Plz help on this issue.
Thanx & Regards
Md Raquib Alam
first of all you need to know what actually happened during ASP.NET Page life cycle and ViewState.
In the ASP.Net page life cycle, two events related with View State.
1. Load View State : Where view state data is loading for the control and which happened before Page_Load.
2. Save View State : Where control data store in a hidden field before the Page_Render.
Now, If you disable the ViewState for the control it should store the view state data but, you are saying in Textbox, after you disabled the view state , control holds the data after postback,
Here is the Trick,
There is another event fired during Page Life Cycle, which is, Load PostBack Data.
ASP.NET controls which implement IPostBackEventHandler will load its value from the appropriate postback data.
This value is not read from view state but from Postback From and this is true for those control which implements the IPostBackEventHandler
and TextBox is one such control Wink
Hope this clears your doubts and This will helps you.

Using membership provider is quite easy in asp.net as ASP.NET internally managed all things. I will suggest you to check following links

Greetings Abhijit,
I came across a response of yours to a query on CodeProject titled ‘Passing Credentials from ASP.NET to OWA’. In your response you state that it can be done by modifying a few files for SSO. I’m using Exchange 2007, OWA is currently configured for forms based authentication, and have coded an ASP.NET page to use system.directoryservices.accountmanagement to validate and authenticate users to the domain.
Please can help me by reply to my email address and let me know how I can achieve this.
Kind regards
Steve
Sorry for late response steve. Yeah I have done that few year ago. I am not able to recall the javascript file name, we have changed only in a javascript file which take the data from our asp.net application. If I found the details I will let you know the details shortly.
Thanks Again !

Hey..Love your articles..Can you please write some beginner articles on WPF?
Hi Abhijit..
I know u through codeproject.. Ur articles are cool.. keep it up.. I have a small issue in my Application if possible can u clarify it…
Im developing a web application here i get datas from the user and on a button click these datas get stored in my data base now i have another button on clicking it,it retrieves all the data from the database and gets saved in my system as an XML file… the code is as follows for the button that creates an xml file…
private void Button1_Click(objectsender,System.EventArgs e)
{
SqlDataAdapter da = null;
try
{
con = new SqlConnection();
con.ConnectionString = ConfigurationSettings.AppSettings["DSN"];
da = new SqlDataAdapter(“select * from card_details”,con);
DataSet ds = new DataSet(); da.Fill(ds,”card_details”);
ds.WriteXml(“D:\ADIB\OutputXML.xml”);
}
catch(SqlException ex)
{
throw new System.Exception (“Error — ” +ex.Message);
}
catch(Exception exp)
{
throw new System.Exception (“Error — ” +exp.Message);
}
finally
{
con.Close();
da.Dispose();
}
}
Now my issue is i need my application to create the xml file,before saving it into my system it should ask me whether to open the file or save the file so that i can specify the file name (something similar to a download window in our web browser)… please advice me… Im using VS2003 .net1.1
Thanx in advance..

Hi
Can you help me?? I read many of your articles and they are very good but I can’t find an answer to my problem. On this webpage is a Frontpage Database that lists all of the videos that we have in our library. When you scroll down and press on the |< >| buttons to go to the next page, it usually doesn’t work. Sometimes it stays on 2/19 when you click on >. Sometimes it works but usually you get something different every time. Do you have any idea what causes that or where in IIS to check?
I have IIS 6.0 on windows 2003 server with Frontpage extentions running.
Thanks a lot, Norman

Hello abhijit,
I m actually confused with cookies & sessions . when user visit website (if its cookies based) then session id is assigned to that particular user in order to send data to & fro .
In case of session, when user request for page & want to store information then again server assign SessionID to user & store information in respective state provider … next time when user request for information, then server respond to user with respect to SessinID .
in both cases SessionID is assigned to user , so session ID is not particular to sessions .. I mean its not inherant property of session state .. ?
One more thing I want to ask in your article Exploring Session , in sql state portion , u have showed data table that stores several information e.g sessionID , created , expires, lock cookie etc etc .. when user request for information , server respond it using his/her session ID & retrieve data from DB , but where that information is stored , in lock cookies?

Hi sir,
I am calling a webservice in asp.net by http basic authentication(RFC2617) but unable to do so despite numerous attempts.
i am not using wcf.
my code is(not working for me):
MyService service = new MyService();
service.Credentials = new NetworkCredential(“username”, “password”);
service.PreAuthenticate = true;
and
MyService service = new MyService();
NetworkCredential netCredential = new NetworkCredential(“username”, “password”);
Uri uri = new Uri(service.Url);
service.Credentials = netCredential.GetCredential(
uri, “Basic”);
service.PreAuthenticate = true;
My client has given me document as follows how to call webservice:
please read about RFC2617 and how to implement it.
It’s clearly mentioned on page 110 of the Integration Document:
Technology Partner Authentication
“Technology Partner”, in the context of this document, means an authorized
“Account” on the IRCTC site authorized to consume the web services. The username and password of the “Technology Partner” is set in the http header.
NOTE: IRCTC Webservices follows strictly, the HTTP BASIC Authentication
(RFC2617), so the same has to be followed by the integrating parties
whether on Java/.NET or any other platform.
i think we have to make custom soap hedaer using httpwebrequest.
plz sir help me.

Hi abhijit,
I have read your article on “Remote IIS Debugging”. When I try to implement it using VS 2010 it’s not working.
Steps I have followed
1) On production environment “Remoter debugger” is not installed, so I have shared remote debugger from my local system and run it on production environment as administrator.
2) In local system I have attach process and in remote machine debugger I am getting confirmation of user connected.
After attaching process I am getting warring(No executable code associated with this line) in breakpoint and debugging not working
Can you please tell me what the problem?
Is there any constraint that application pool on remote server should run on my credential (now it’s working on some service account credentials) ?
This warrning is for all breakpoints or any particular breakpoint ? Just try to put a simple break point on page load of current page and let me know the result.
Hello Dear Abhijit,
First of all i want to thank you for sharing your very precious knowledge and helping others to learn new things from my side and Mr. Abhishek Sur, ur old friend.
and i have one query,
i want to create exactly the same menu for my friend’s project that you’ve created here in this website.
I’ve tried to create it and even succeed partially in it.
I’ve created a horizontal navigation list like your’s in this website in the master page.
By default the Home page’s menu item has a background color (different) as it is selected by default which is different from the others
when i click a menu item, i’ve a javascrpt code(in the master page) which is changing the background color of the selected menu item based on the id supplied by the list item to the javascript function.
but as the page load life cycle again happens and by default Home page’s menu is selected instead of changing the background color of the selected page, the Home page’s menu’s background is getting changed(coz of page life cyle).
please suggest some idea about this.
Do i’ve to do it on server side by maintaining state???
Thanks in advance
Manjeet,
Thanks for writting to me. Are you usign ASP.NET Menu Control or any custom control ?
Thanks

Hi Abhijit,
I read your Article about deploying ASP.NET Applications on IIS7.0 (http://www.codeproject.com/KB/aspnet/IIS7ASPNet.aspx) and i have the same problem:
I get a NullReferenceException when my Application tries to read the Sessions, i can set them without any problems…
But if i want to configure my IIS with other options than in proces, my application gives me a configuration error…
Could you pls give me some advice how to solve that problem?
Many thanks in advance!
Please let me know the exact configuration error that your are getting ?
Thanks!
It did say something about the SQL-ConnectionString, but i fixed that a minute ago, so the problem remains…
Now the Session state should be saved in my local mysql-server.
But the Main Error, is the same…
I can give you the error description:

It means you are trying to access some varible which is null. If you are trying to retreive information from Session like string name= Session["Name"].ToString(), Before doing that do a null check of that session variable like,
if (Session["Name"] ! = null )
{
name = Session["Name"].ToString();
}
Hope, you got my point.
Hi,
yeah got it…
I just was to sure, that the variable will be set…
With the test for null, i can be sure, that the corretc page will be loaded!
Many Thanks!
Keep up the good work!

I read your web farm article and it’s very nice.
i want your little help.
is it possible to upload multiple file on a single browser click in .net
n if yes
then how can i get this.
thanks in advance
Satish
Thanks ! and nice to know it helped you !
Normal ASP.NET File upload control allow only one file to select. What I understand from you query is you want to select multiple files at a time . I think for this case you can go for Flash Upload control . Here you go
http://www.codeproject.com/KB/aspnet/FlashUpload.aspx
Or you can do, you can use list box to add file name one by one, then upload at a time. like
http://www.codeproject.com/KB/user-controls/MultifileUploadUserContro.aspx
Let me know if u need more help !

Hi Jacob,
Performance wise State server is better as its stored information in memory where as in SQL server, session data stored in disk.
I would request you to please go through this link for details.

Hi Abhijit,
after i published the ASP code in IIS 7 , and when i open the site at any client site , i cannot see the image , its shows only cross mark, how to resolve this issue
Gnanam
Sri Lanka
Hi Gnanam,
Just right click on the Red cross mark and click on the properties. Check the what Image path its coming. I guess this is wrong path . Please verify your code what type of path you have given (absolute / related ). Best to use “Server.MapPath() in this cases.
Please let me know if this helps you or if you need any more info.
Thanks !
Abhijit
Hi Abhijit
all the paths are correct , i have given below the image link code, please show me how to use Server.mappath
i have tried with the same code in Apache Http 2.2 , its work fine , but i don’t know why AJex controls are not working in Apache Http 2.2
Thanks
Gnanam
sorry , i have attached the link belw
asp:image runat=”server” id=”Image1″ ImageUrl=”CompanyLogo.png”
When working with resources in a Web site its always beeter to use Server.MapPath() to give the reference path. For example, you might use a URL path to reference an image file in a page or the URL, if use SErver.MapPath() , this return the physical file path that corresponds to the specified virtual path on the Web server.
String imageFilePath = Server.MapPath("/Images/MyImage.jpg");Hope this will resolve your problem.
I am using VS 2010. It has default ajaxtoolkit loaded.but i cant drag and drop it in webform.why?
Are you getting any error while Drag and Darp ?
Hi Abhijit
thanks for your information , but still , i could not able to view the image after publishing. if i send the program can you check and let me know where i made the mistake , i would like to know , do i need to enable any option in IIS 7 , because , i have published in Apache Server , its working without any issue.

Thanks and nice to know my articles helped you !
Before thinking of certification, you should know in which technology you want to do the certification. Microsoft having many topics for certification. But, you have to be specific on your requirment. I guess you want to do certification on .NET, may be Windows or Web Application. For that you have to look for MCTS Exam details from microsoft Learning sites.

Hi abhijit ,
We are running a problem for a few days. We have developed a web application and deployed it in IIS 7 but the problem is that it hangs after every 3 minutes. We have analyzed a lot and we fond that Worker process recycled the application pool because of Private memory or virtual memeory but we didn’t set any limit of virtual memery. We also tried memory leaks software(APNT profiler) to find where memeory leaks but it shows us System.string(taken Highest memory). Please give us a solution…is that problem of IIS 7 or anything else..
Hello Abhijit Jana,
Thank you for your great posts. I have a serious question about bing maps and silverlight, using geocoding (http://www.codeproject.com/Articles/95096/Bing-Maps-Silverlight-Control-Integration-with-Sha.aspx?display=PrintAll)
The problem is the
geocodeService.GeocodeCompleted += new EventHandler(geocodeService_GeocodeCompleted);
I have to call the Geocode function in a loop, searching for multiple locations in a time. But the problem is that the event doesn’t happen in time, and that causes the loop to continue and override the previous value. Is there a way to Geocode without an event?
Help me please!
Thank you very much!
Hi,
I am very beginner for asp.net,
In my application i used session variables, and i am checking one session variable in all pages..
after 20 minutes the session is expired..
Now my question is,
Is there any way to get session variable value after expired?..yes there is a way Session_End method in global.asmx…but how can i use it?
if you give some example, then it is very helpful for me..
bcoz, in my application, once the session is expired, it will redirect login page..
and the login contains the module id, at the time of login i am storing the module_id in session..
so if the session is expired, then i need to pass the module id to the login page..
like “Login.aspx?Module=” + variable name contains module id

Hi Abijit,
….
your world of .net is very informative
Have a question..I m hving a datagrid in web page n some of the cells in grid are having dropdowns the list count of each dropdown control is around 5000 records.
when i add new row to grid i want to avoid call to database to fill the dropdowns.
In this scenario should i use cachin or load data into some staic variable like array…
need ur inputs
Hi Raj,
why are you trying to show 5000 records in a dropdown list ? You can only show those records which are relevant. I am asking, why you are not applying any filter first to show the records in dropdown. I guess, the value from the list can be selcted by the user, then selecting some value from 5000 records is not a good option.
What do you think ?
thanku for ur reply…
ya true …i wana apply filter like this..i ll display a textbox ,as soon as i start typing the part id in textbox the listitems both(partid n description) should start displayin..for example google search
Yes, like Auto complete text box. You can also do the same using XMLHTTPRequest . Let me know if you need any further help.
Thanks !

Please let me know your views whether should I go ahead with the assignment. I am afraid that my .NET skills will go obsolete because assignment will go for next 6 months. I request you to please throw some guidance.

I am writing a document on “Deploying websites using VS” and planning to post it on our Knowledge Management intranet, so that other employees in my company can also benefit from reading it. I came across an article, Deploying websites using VS2005, written by you on the same subject. I would like to include this in my document. I request you to kindly grant me permission to do so. I assure you that I would give appropriate credits and references to your article in my document.
I intend to reproduce in my document.
Ref : (http://www.codeproject.com/KB/aspnet/VSDeploy.aspx)
Nice blog and nice content. I found this site while I was searching a silverlight-sharepoint problem. I’m a silverlight developer and now there is a challange with connecting silverlight and sharepoint. When I try to use ClientContext, it’s always returns null. Is there any setting trick for connection? Because I did all what you said in your articles.
Thanks
I replied you on the article post !
hello sir i Have a problem.I have used caching from my application .when I run application on localhost it shows information correctly but when data is fetched from server where site is uploaded it shows error:
The current build operation (build key Build Key[Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter, null]) failed: Request for the permission of type ‘System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′ failed. (Strategy type Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.ConfiguredObjectStrategy, index 2)
Amit,
From the error details, it is clear, that your issue is not with caching. You are writing log using Enterprise library. It worked fine when you run it from VS IDE. As VS IDE having sufficient rights to write on your drive. Now as you said, you have hosted in IIS, I am sure you created the application pool as well. By default your application pool will run of Network service Identity which does not have the privilege to write on your drive. Because of that, I guess you are getting the error. What you can do is, change the application pool identity to Local System or Use Impersonation to write log. Or Give write access to the log write folder.
Hope this will help.
Thanks

hi abhijith,
I have two question on the asp.net session management session given by you today.
1 Does the enableviewstate property becomes absolute as new property ViewStateMode is introduced?
2. What kind of compression is used to compress the session data in the state server?
Suresh,
You can still use enableviewstate mode to take control over the whole page. ViewStateMode will help when you want to take control for each and every page control.
ASP.NET 4.0 used System.IO.Compression.GZStream class to compress the session mode
I have posted an Session Summary note over here, you may look into that.

Hi Abhijith,
I have a question, please clarify.
I have a class called PageInfo and it has a propery Name and lets say i have added this class object to a session,
and i can read the object added to session in the following two ways and change the value “Name” property.
first way:
(Session["test") as PageInfo).Name = "SomeName";
second way:
Page objPage = (PageInfo)Session["test"];
objPage.Name = “test”;
What is the difference between above two approaches and which one is the best practice?

second way:
Page objPage = (PageInfo>P"];
objPage.Name = “test”;
What is the difference between above two approaches and which one is the best practice?
Hi Suresh,
For Both the cases you ar doing the same thing.
Let say I have a class called Student
internal sealed class Student
{
public int Roll { get; set; }
public string Name { get; set; }
public string Bio { get; set; }
}
Creting and storing the Student Object
Student s = new Student{Roll=7,Name="Student 1",Bio="No Bio"};Now, You are storing it into Session like
Student["stud"] = s;Now when you are updating anyvalue, first step you are following is
(Session["stud"] as Student).Name = "Student Name";Which is nothing but the type casting the session object and setting the Name value.
And in Second Approch,
Student ss = (Student)Session["stud"];ss.Name = "student new name";
Here you are doing one extra one object “SS” initilization. Which was not required
So, I will prefer the first option. But before that I will think why to store an complete object in session ? If I need to store only few properites they why no to store only those properties instead of all object. We always have to take care of session data size.
Hope this clear your doubts !
Hi Abhijith,
though that clears my doubt.., i thought you would explain me the solution is IL language perspective..,
my question is even in the IL an extra object is created and occupies some memory when we follow the second approach?
Thanks
Suresh Kumar
I will write to you details soon !
Hi Suresh,
Well, in IL, as far as I know, each method declares locals in the first section and the instruction set thereafter. If you are dealing with ValueTypes, even though you create extra memory for storing your object (provided you are using struct not sealed class), the object is created in Thread stack, and it will be cleared as soon as the object is sent out of scope.
On the other hand, If you look for objects, even though you assign / cast an object coming from Session to your reference, it will only transfer your reference. Actual object creation in the heap only takes place when you create using new operation. If you are cast an object reference to a variable, it will not create additional memory to store it.
Hence the entire doubt centered on your mind doesn’t need any water. I hope you got my point.
Abhishek thanks !
Cheers !

return Result;
}
and now I am writing the code like this
Add(1, 1);
The method with Int32 will be called.
I want to know y this happened? Wt’s the reason behind the compiler picking up that (Int32) method?
Because By default its Int32. Try to declare variable like Int16 i=10; and Int16 j =20 and Call Add(i,j), It will invoke public int Add(Int16 X, Int16 Y)
. Then Try Int32 i=10; and Int32 j =20 and Call Add(i,j) this will public int Add(Int32 A, Int32 B). As default is Int32 which we used as alias int, its called public int Add(Int32 A, Int32 B)
.
Hope this clears your doubts !
Cheers !
AJ
Its awesome explanation. Now clear.
Thanks for prompt response.
Cheers !!!

Hi Abhijit,
In your article on Exploring Session on CodeProject.com, you have shown a different SQL Server than the replicated DB servers for storing session in SQL Server mode. Can’t the same set of DB servers be used to store the session?
Please advise.

I think your network spy is perfect! You did a great job on creating it.
On the created, deleted, renamed and changed – how can I see which user (on a network) did it?
I am a Network Systems Administrator and need a good program (like yours) to monitor our users.
Thanks
You can use this tool. I did it long time back, and haven’t work on that afterwards. No, detecting changed user is not there ( You will able to see who is accessing, but no more details user ). On that time I couldn’t find any API to get the exact user name who did the operation. I was talking about the same with one my friends just few weeks back. I know this tool could be extend with many new features. There are some issue with that tool as well. I was thinking to resurrecting NetSpy and start a fresh development with same idea. Let see.
Thank you !
You said “There are some issue with that tool as well”. Can you give more detail? Will this hurt my Network?
No, it won’t hurt your network, but some people reported some crashing issue, you can read the discussion on articles.
Crashing of the network / server or crashing of your utility?
It’s on the utility !
Just to clarify – I am using your project located:

Hi Ram,
You have to make sure the worker process are running. If yes, then you should able to see the, Other wise check this ( You have to select process from all session / users )
http://abhijitjana.net/2011/08/18/no-able-to-view-all-the-running-worker-process-in-visual-studio-process-attach-window-resolution/
For Remote process debugging you have to check security settings in msvsmon.exe. I have one article @codeproject on the same

Hi Abhijit,
I’m spending too much time on this and I am having so much trouble just freezing a gridview header it is ridiculous.
I came upon your site through an article from code project and then to your own site.
I am using just a gridview inside of a div and can’t get the gridheader to freeze.
I can send a striped down version of the grid/css.
Let me know your thoughts!
Thanks so much!!
Jim

Hey Jim, Where are you getting the problem ? Did you try with the sample in CodeProject Article ?
Hi Abhijit,
Here is the code I am using as far as the gridview and the css
css:
.HeaderFreez
{
position:relative ;
top:expression(this.offsetParent.scrollTop);
z-index: 10
}
I didn’t do the project in code project just that I didn’t need the update panel, etc. I just need to freeze the header.
Thanks,
Jim
asp:Panel ID=”pnlGrid” runat=”server” ScrollBars=”Auto” Height=”350px”
asp:GridView ID=”gvData” runat=”server” DataSourceID=”sqlDataSrc” AutoGenerateColumns=”true” AutoGenerateEditButton=”true”
HeaderStyle CssClass=”HeaderFreez” Wrap=”false”
RowStyle Wrap=”false”
AlternatingRowStyle Wrap=”false”

Here is the code. I hope it works this time.
Jim, this should work. Which browser are you using ?

I have deploy an asp.net website to IIS 7.0 with an Apache server running using ProxyPass to redirect. When asp.net has to do a redirection (e.g.you try to go to a page and you are redirect to a login screen automatically) I am getting an error “The resource cannot be found” . This is because it trying to find the page at the wrong url (e.g when it should be http://MyDomain/Admin/User.aspx, the URL is http://MyDomain/Site/Admin/User.aspx) where Site is the actual name of the virtual folder in IIS. Help please

Hi !
I’m working with an web application project for my study.. I have some problems and i dont have muche time
- am using listView which it bounded to myDatabase, there is a Button under the text @ItemTemlate for every generated item in the listView (onPage_load), HOW can i get the productID for this item ??? i need the id to use in code behind to send all the info about the product to the myCart site .
- I want to update a text on siteMaster when i add product to myCart, to showing the quantity and myCart site and the total cust.
- What is WCF ? and how can i use it ?
I appreciate any help as soon as possible, thank in advance
Best regards
You can simple get the product id from the source of data. you can use ItemDataBound event to bind with every item. Try e.Item.FindControl() get the button control and do what ever association you want to with it.
Check here,how ItemDataBound works http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listview.itemdatabound.aspx
Thnx for answering !
I dont know how to do.. am using Button click Event and in there is no e.Item or command.

Hello Sir,
I am .net developer , i have a query regarding caching.
i am using caching which is updated and reflected properly through out site. but when i am using it in Quartz scheduler it uses old data. whether i have update it or not.
and right now we have to reset the scheduler.then it will use new cached data.
so might be Quartz scheduler caching is override existing one.
Please let me know if you can solve this issue.
Hi Megha, Could you please explain in details. It’s not clear to me.
Hi Abhijit,
Actually I saw your Kinect Tutorial Part I. I am using Kinect SDK 1.0 and Visual Studio 2010 but I do not get Microsoft.Research.Kinect.dll file and not getting Runnable class. So We need your help.
Hi, from V1 the API changed. First of all you need to include Microsoft.Kinect instead Microsoft.Research.Kinect. Secondly, no more runtime class, just use
KinectSensor sensor= KinectSensors.KinectSensor[0];
Get the details of API Change from here,
http://robrelyea.wordpress.com/2012/02/01/k4w-details-of-api-changes-from-beta2-to-v1-managed/
Let me know if you need any further help.
Thanks for your support. Its working.
Great to know. Let me know if you need any further Help !!
Actually I want to find out the distance of multiple person(or even a single person) in cm or mm format. Can you tell me how can I find out this?
Thanks in advance.
Hi Abhijit,
I actually how to find out the distance of a person (single or multiple) from the camera. I tried out Skeleton demo and Explorer demo of Kinect SDK but I want to know distance of a particular person in each frame. Thats all.
Thanks in advance.
Hi Siraj,
Distance calculated based on the below formula,
int distance = depthFrame[depthIndex] >> DepthImageFrame.PlayerIndexBitmaskWidth;where distance is in mm. DepthImageFrame.PlayerIndexBitmaskWidth is the constant and value is 3. depthFrame[depthIndex] is the pixel value with in the player range. Sensor sends raw 16 bit depth data where first 3 bit used for player index that is the reason there is a bit wise shift operator with 3 bit (DepthImageFrame.PlayerIndexBitmaskWidth ) . So, rest high 13 bits represent the pixel distance in mm from sensor. Hope this clears your doubts.
Let me know if you need additional help !!
