Classic producer-consumer-problem.I have x app servers which write records in a DB table (same DB).On each server,a service is running which polls the DB table and is supposed to read the oldest entry,process it and delete it.
The issue is now that the services get into a race condition: service on server A starts reading,server B starts reading the same record.I'm a bit stuck on this.I have implemented producer-consumer so often but never across server barriers.
The server cannot talk to each other except over the DB.Environment is SQL Server 2005 and ASP-NET 3.5.
I understand the producer consumer pattern but I'm finding it difficult to map it to using the Entity Data Model and SQL Server 2008. I want to implement a work queue where multiple threads will pick up the top 5 items (each) to work on and then perform somelong running task on each of those.I've googled for a an example of this but I can't seem to find one that uses the Entity Data model and C#

Is there a way to get information about the web site or application that is consuming the Web Service. I would like to determine the details of an application from within my Web Service when it is consumed. The information would be like that in the assemblyInfo of the caller, application name, version etc. Getting the user seems to be easy enough but not details about the application or web site.
I am working in one of the company which sells music online. we want to white label our website so the different consumer can use our download store with their brand name.
I have a site that is running on a Windows Server 2008 machine with IIS 7.0, when I try to open it with Visual Web Developer 2010, it says the following:
error: unable to open site: ... The Web server does not appear to have FrontPage Server Extensions installed.
Looking on the server Frontpage Extensions 2002 are installed, so what could be wrong?
The thing is, I used to be able to open the project and work on it, etc...
Open Website -> Remote Site -> Enter remote site name -> tries to open & error above!
This issues has been driving me nuts. I am trying to follow the tutorial on [URL] I am trying to connect to a database in Microsoft SQL Server 2008. The way I do this is by right clicking on the "Data Connections" > Add Connection. Afterwards the Add Connection window comes up, I make sure my data source is "Microsoft SQL Server (SqlClient). And, I choose a server name; the only server I can choose is DomainSQLEXPRESS. The issue is when I go down to the "Select or enter a database name" drop down box, I do not see my database listed. I have also made sure in the SQL Server Management Studio that I have given my user all the privileges for the database. I know my explanation is kind of vague, but would anyone know the reason why I would not see my database?
