• Visual Studio 2008 (Pre-release) How to Initialize COM-Object and share it between WCF requests?

  Hi all! I created a WCF service, which I host in a windows service. In the methods of the service I create a COM object and use it to get data or modify it. But it takes a long time (2-3 seconds) to create the COM object with the 'new' operator. I don't want to do it for each method call. When I create it in a constructor, then the constructor is also executed for each request. How can I share a COM object between all WCF requests Kaan Ozturk Hi Kaan, You're correct that you can use a singleton service to share data across all requests. You just need to make sure the ServiceBehavior attribute on your service class has InstanceContextMode = InstanceContextMode.Single. You can then initialize your ...Show All

I want to use 2- way databinding,with gridview,for which I can use objectdatasource..should i create an objectdatasource object representing my domain,since my classes in domain wont follow pattern required by objectdatasdource.. 2...In MVP pattern,how to trransfer data from presenter to model..use a dto,or directly model classes.. thks I think you mean MVC.

• SQL Server SSIS Higher Level Edition error when run in a Sql Job

• Visual Studio Express Editions Long Delays when accessing files

  Anytime I attempt to retrieve a file, or save one, VB2005 Express first does a real long access to to net, sometimes it's so resource intensive it freezes my computer, then eventually alows me to continue navigating to the file. If I disable my network adapter it acts normally. What is ittking for and how do I make it stop. After a great deal of trouble I was finally able to uninstall all "express" packages from my computer. I will have to wait for a computer to become available in order to reinstall them on a non-production computer. That's a pity, though, as I desperately wanted to learn VB.NET and start this project using only that and SQL. ...Show All
