• Re: Extending columns/fields of entities without changing code.

  You can try some of the O/R mappers. NHibernate for example can generate the SQL DDL for your entity model. So when your class properties change, you can add the properties to the mapping file , and have Nhibernate generate the SQL DDL to change the structure of your tables. http://www.hibernate.org/hib_docs/nhibernate/1.2/reference/en/html/toolsetguide.html The Nolics OR Mapper does this automatically during initialization.

• Re: Sessons vs Viewstates

  Hi May, ViewState is available within the same page only. Values stored in the viewstate of one page cannot be accessed by another page. If you want to share information across pages use the Session object or the Cache object. Use the Session object when you want to store data that is unique to a single user visiting your site. Use the Cache object to store data that is shared accross your application (ie : common to all users and pages ) http://msdn2.microsoft.com/en-us/library/ms972976.aspx Hope

• Re: Http Error perspective

  Hi, yes, it would be a bad idea to raise an HttpException. The scenario you describe is not something that is handled by an exception. You shouldnt use exceptions for this scenario. It is better handled by a "IsRequestValid" method that returns a boolean. if(! IsRequestValid()){ //redirect to page with message "You cannot access" } Exceptions should be used to handle abnormal situations. Hope this helps..

• Re: uploaded files and load balancing

  I've done a similar project. I've mapped a virtual directory that points to a network path on a remote fileserver. All the load balanced webservers share the same file store location.This makes the location same for all users. Each time you add a loadbalanced server you just have to configure the virtual directory to point to the remote network path

• Re: ASP.NET website that needs to be able to send 800 simultaneous http requests for each page view.

  wouldnt it be better of to do the search in a middleware component ? The user's search request can be send off to a seperate component that will send off the requests to the different suppliers and collect the results. you would be able to cache common searches this way rather than having to send 800 requests each time. This is a better approach to look into. Your asp.net page makes a request through remoting to a windows service sitting on another server, which then sends the requests to the

• Re: WS problem:Unable to connect to the remote server

  It sounds like the HTTP POST verb is blocked or not setup for the .asmx extension. Does POST to a web page work ? i.e simple form witha few fields. If you are daring you can test with a file upload form, and try different file sizes, to check if there is a limit on how much you can POST.

• Re: WS problem:Unable to connect to the remote server

  Hi Brad, A network error can mean many things, the web server hosting the webservice not running, your client machine cannot physically access the server hosting the webservice etc.. What I suggested was a few tests to isolate the problem and test basic connectivity. From your client machine try to access a page on the server hosting the webservice. Do you have any other sites hosted on the same webserver/farm that are working ? . This test will show if you have network access to the server. If this
