Calling a Web Service Method Asynchronously does not work in Console Application

I have a web service that has a CreateReport method that generates a report based on the specified criteria. When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created. When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created. When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.  I am using VS2005 and .Net Framework 2.0.  So the proxy is automatically created with the Async methods.  I am not really interested the result of the method call, so I do not add a Callback Delegate.

Is there a work-around to create indexes for a view defined by a sub-query, derived table, or CTE?


I have three versions of an indexed view I'd like to create. I can create the view, but cannot create a clustered index on (CollectionID, ElementID, TimeID) because the definitions use variously a sub-query, CTE, or derived table, which SQL will not allow.

Has anyone figured a workaround for this? Any suggestions much appreciated.

Looking for guidance: wanting to work with AJAX architecture



I'm starting a small website that will be backed by a database, and will allow a small number of users to authenticate and select an entry in the database, and then view (and optionally update) a corresponding entry (think master-detail).

I have some flexibility in how I'll do this, but I'd really like to incorperate some newer AJAX style coding, eliminating some page postbacks. I think this is a great opportunity to learn the concepts well.

I'll probably go with an ASP.NET 4.0 site. From what I've seen there are MANY ways to go about this:

-WCF Data Services to expose the data, and consume in ASP.NET

-Page methods to expose the data, separate method to update the data

-I'd rather avoid the UpdatePanel because I'm really looking for a full hands-on approach, with learning client side scripting being an objective as well.

Beyond that, it seems that one can use jQuery to build clientside templates, but also one can use the ASP.NET AJAX template engine (in ASP.NET 4.0 I believe).

A concern I have: users should only be able to work with the data exposed via these endpoints if they are logged into the website. Hopefully I can somehow reuse the ASP.NET forms authentication cookie for this purpose. 

Well, I hope I've posted enough to a

animate effect work but the render items are messed up.


Hi all,

     I have a very unique problem, humm i think. I am using a jquery effect that animate bounce effect, i have a line in my javascript pageLoad function $("#UserBrowserInfoDIV").show('bounce'); - the effects run smoothly but what it does is mess up the bolded text in the div. I have try the items inside the div without bolding and it works fine and no render problem but when bolded the text that are bolded is quite messed up, and barely readable.

Please let me know is there anything else i can do i really would like use this effect.

P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.
