How to send and receive unique cookie to a user

Posted By:      Posted Date: October 10, 2010    Points: 0   Category :ASP.Net

Hi, I need to send a cookie to the my web site's visitors and receive them back for information. For example when machine1 visits my site if not set I set a cookie with "user1", for machine2 I set "user2" etc. 

Actually I need to retrieve the cookie back from my log file, so I thought if I do this it will be saved to my log file. Any help?

Thanks in advance

User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

Programatically Send and receive data using Post Method

How to Send/ Receive Class/Structures with TCP using C# .Net...

Here I am looking out for 2-things! 1) A pointer/ notes on how to send/ receive data (a class object or structure) across the network using TCP/ UDP between 2-Windows machines. 2) However, the higher priority thing for me, as of now, is sending/ receiving data (a class object or structure) across the network between a WinXP machine(client-application) and Linux machine (the server application). Working with ‘unmanaged code/ WinSock APIs’ will be the only solution? <Note-1> Here, I am NOT looking to transfer the file/s OR FTP or something similar. Its purely objects/ structures. <Note-2> A cursory look suggested that NetworkStream and BinaryWriter can help me achieving data transfer between Windows PCs. _______________________________________________________________ Say, an example structure I need to Send/ Receive across is:     public struct Message2Linux {   public int MsgId;   public int paramCount;   public int[] paramArray; };     Many thanks in advance.

Catch when user login cookie has expired. How to?



I have an ASP.NET MVC application that uses the Forms Authentication. I have the following configuration block inside the Web.Config:

<authentication mode="Forms">
  <forms loginUrl="~/Login/LogOn" name=".td_gsl_login_cookie" timeout="10" slidingExpiration="true" />

So if the user does not click any link for 10 minutes it will be disconnected and redirected to the LogOn action at the next click. This works very fine in my app.

Now what is really annoying is that I have some links in my app that open up a modal popup window (using jQuery UI) who retrieves their content dinamically using ajax requests and if the user click on one of these links after his login timeout has expired the result is that the login page is showed inside the popup dialog. The effect is really bad...

I understand that developing a script to check if the user is still connected would slide the cookie expiration.

Do you have any suggestion on how to address this behaviour?

thanks for helping






The user does not exist or is not unique


We have just used the following link to update our object cache user accounts and after IISRESET we are now getting the above message, and are unable to access our intranet site.

We created two new AD accounts with minimal network privileges, as these would be defined within the Central Admin, as either Full Control or Full Read.

Has anyone else updated their Cache Users and did they have a similar problem, did they create new AD accounts for this or use existing ones?

Quick turn around would be nice, how can I tell what setting has been made within powershell for the portalsuperuseraccount and portalsuperreaderaccount.

SPD workflow doesn't send email to user in list when automatically started

Hi all,

My first post here and I hope someone out there could kindly help. I recently found out a strange issue with my SPD workflow. Basically, it couldn't send out email if (1) the recipient resides in the list and (2) the workflow is automatically started.

For example, I have a list with a "user" field. A workflow first "Send an email" to this user, and then "Collect data from a user" from this user. If the workflow is set to start automatically, then this user gets no email. Tasks list does contain a task, but the "Assigned To" field of the task is empty. This is the case no matter if the user field is of type "Single line of text" or "Person or Group".

Everything's fine if I manually start the workflow. And everything's fine if the user is directly spelled out (jay@company.com) in the "Send an email" and "Collect data from a user" actions instead of retrieved from the list. Either case the user would get two emails as expected, and the "Assigned To" field would display the user name properly.

I looked into the log but didn't find anything special. As you can imagine, this is breaking a lot of our workflows and making SPD workflow look very bad. It's just not

I want to send user to different pages based on their roles



I'm using the built-in membership controls and classes to manage authorization and authentication in my app.

Here's what I want to do:

If the user is in "Manager" role, I want to send him/her to the manager page no matter where he/she came from .

If the user is in "Supervisor" role, I want to send him/her to supervisor page no matter where he/she came from.

However, if the user is not in any role, just a registered member, I want to send him/her back to where he/she came from as stated in ReturnUrl. If no, ReturnUrl is specified, I will send him/her to the home page.

On my login page, I'm using the Login server control but in my code behind, there's no method wired to the control because the control takes care of everything.

I assume I need to add a method and wire it to the submit button, is that right? If so, I'll have to really handle the login event which means I'll need more info about how to do that. So I'd appreciate some pointers in how to do that. Thanks.

Pick with receive/send reply behavior

Hi all,

I have this workflow (simplified view):

				<Receive CanCreateInstance="True"/>

The LongRunningActivity is a code activity which runs another workflow [through Task.Factory.StartNew(() => workflowApplication.Run())] and waits with a ManualResetEvent the completion of the inner workflow. The inner workflow contains other receive activities.
This is the Execute code of the LongRunningActivity CodeActivity:

WaitHandle waitHandle = new ManualResetEvent(false);
        // ...
        WorkflowApplication workflowApplication = new WorkflowApplication(definition);
        workflowApplication.Completed = args =>
        Task.StartNew(() => workflowApplication.Run());

When I run it, I have the same behavior:

Get the unique session for the user



Here's my scenario, a user logs in to the sharepoint site and visits a document library, then I have this webpart that gets the username of the user and stores it in the database, however, my problem is that whenever the user refreshes the browser(press F5), another session ID is thrown to the user meaning, my code will again put the username to the database and it will now have 2 data/record in my database.

What I want to do is that whenever a user visits a document library, the username will be stored in the database once, or until he logs out or after a certain amount of time. and if the user refreshes his browser(press F5) it will not count as a view/hit therefore, the username will not be stored to the database.

I've been trying this with alot of if statements however I cant find a way to handle this. I think i really need your help again.
