How do I manage the interruption of a booking procedure by the client in WCF?

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :WCF
 
Hello there, I've been reading around about session management in WCF and Silverlight 3 but didn't find exactly the answer to my question, so, here it is. I want to develop a silverlight application that provides a booking procedure for a limited set of goods. As the user selects the good he/she wants to book, this should make a temporary reservation at server side to avoid that other users could ask for the very same good on the very same date (at least as long as the first user is carrying the procedure along). In case the user terminates the procedure before confirming the booking, or in case the "session" times out or the browser gets closed, I need to detect at server side this event to release the good for other potential users. What would be the most reliable method to achieve this? Thanks in advance for any suggestion/tip you will provide..

Use jQuery and ASP.NET AJAX to build a client side Repeater

  
By sending only data to the client, you can profoundly reduce the size of what you send and see a substantial increase in performance. You also allow yourself the ability to easily add features like light-weight sorting and paging on the client. This can not only improve your users' experience, but reduce server load and bandwidth requirements.

Practical Multithreading for Client Apps

  
Writing applications that use multiple threads is often considered an advanced programming task, prone to errors. In this month's column, I'll focus on a practical application of multithreading in Windows® Forms applications with some real benefits, while attempting to keep things simple. My goal is to present multithreading in an approachable way that addresses a very common need: writing applications with a user interface that remain responsive to the user.

Adding Client-Side Confirmation When Deleting

  
The JavaScript confirm(string) function displays its string input parameter as the text inside a modal dialog box that comes equipped with two buttons - OK and Cancel (see Figure 1). The confirm(string) function returns a Boolean value depending on what button is clicked (true, if the user clicks OK, and false if they click Cancel).

Send Email from SQL Server Express Using a CLR Stored Procedure

  
Problem
One of the nice things about SQL Server is the ability to send email using T-SQL. The downside is that this functionality does not exist in SQL Server Express. In this tip I will show you how to build a basic CLR stored procedure to send email messages from SQL Server Express, although this same technique could be used for any version of SQL Server.

Solution
If you have not yet built a CLR stored procedure, please refer to this tip for what needs to be done for the initial setup.

Client script not running

  

Dear all,

in my MVC 2 application, and in the shared Master Page I wrote this little script for menu handling :

<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript"> $(document).ready(function () {   
       
     $('#nav li').hover(  
         function () {  
             //show its submenu  
             $('ul', this).slideDown(100);  
   
         },   
        function () {  
           //hide its submenu  
            $('ul', this).slideUp(100);           
         }  
     );  
       
 });</script>

Inserting rows via stored procedure and under certain conditions

  

I'm using Dynamic Data with Entity Framework in VS2010.

Let's say my table has these fields:

MyTable
ID (PK)
PersonID (FK)
LocationID (FK)
TotalItemsSold

Hypothetical scenario (it's easier for me to explain this way, so just bear with me for now)... But let's say each row in the table represents "how many items were sold by such-and-such employee at such-and-such location," where location and person are foreign keys which are referencing other tables.  Basically, there should be no more than a ONE row which has a particular combination of Person and Location.  Makes sense?

So, when inserting new rows using my Dynamic Data app, the insert form displays editable fields for Person (dropdown), Location (dropdown), and Items Sold (textbox).  How do I prevent users from inserting another row into the table containing an already-existing combination of Person and Location?   How do I displaying useful feedback to them in the event that they DO attempt to do this?

I have several thoughts about this, but since I'm new to Dynamic Data, I'm not sure which way to go.  For example:

Option 1:  Use "cascading dropdowns" approach in the insert form and only pull in the "allowed" combinations of the two dropd

Problem to obtain client IP on web service

  

Friends,

I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP 10.0.2.50 and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP 10.0.2.51 and host name ServerApplication.
Many other computers on the local network (IPs: 10.0.2.80, 10.0.2.81, 10.0.2.82, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (10.0.2.51).

Any idea or tip?


Thanks and sorry for my bad english.
