If the user name was linked to their Windows Identity, then you can use that. If, however, your site uses a custom login mechanism or something like OAuth, then the user is going to have to associate their identity with the notification application - this would typically require you to provide a settings page where they entered their user name and password details so that you could verify that they were a valid user.
To be honest, this opens a whole can of worms, including things such as verifying that web service requests haven't been intercepted and so on. A simpler method would just be to email them.
I was brought up to respect my elders. I don't respect many people nowadays.
I am getting a timeout message when accessing a linq to sql object in a C# 2010 application. This error message is occuring when I am doing a select in the linq to sql object. thus can you tell me how I can increase the timeout on the linq to sql data set object? The following os the error message I am getting:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

1. You already posted a similar question a while back. I suggested logging. Did you implement that? Logging a stack trace is not enough.
2. Try setting a break point in the catch that generates this message and check your variables. In LINQ you should be able to retreive the SQL that is sent to the database, find it and try to execute in SQL Server directly. If necessary, type it over in the SQL manager by hand.
3. A timeout is there for a reason, you should only increase the timeout if you're absolutely certain that procedure is lengthy. Honestly, based on your questions I don't think that is the case here. increasing the timeout could at best, be a workaround, not a solution.
I'm assuming you're talking about this[^]. Start there and write your own code. It's what you're going to school for or getting paid to write isn't it?? Either way, we're not writing your code for you.
