• Visual Studio 2008 (Pre-release) Orcas Mar CTP Samples?

  Are any/all of the EDM/LINQ samples included in the Mar CTP I've been successful forward-porting the October EDM samples, but I don't see any samples in the CTP itself. Am I missing something obvious Thanks, Bob I hope that they work on documentation for future releases. I was impressed with the level of documentation and samples since the initial PDC LINQ CTP. Finding them in this drop has been an effort in frustration. I'm wondering if they are just planning on ripping the previous documentation and putting it in a MS Press book. So far it has been hit and miss on migrating code from the May CTP (yeah, I know this is slightly the wrong forum.) Trickiest things so far have been the changes in query ...Show All

• Visual C# How to pass a method as a constructor parameter

  I have a Counter class that runs in parallel to the main form of my app. I want the counter to know the method in the main form to call when the counter stops or reaches 0. How do I pass the address of the method in the main form to the counter in C# This would be fairly easy in C++. Or, would it be better to generate an event that is "sent" to the main form like somebutton.Click += new System. EventHandler ( this .timer1_Tick); Can I do: counter.something += new System.EventHandler(this.counterhandler_method); Thanks. Thank you. I just read up on delegates and event handling, and I think I got it. However, I wasn't thinking of passing the form to the counter. I wanted to know how to pass an arbitrary method ...Show All

• SQL Server Dedicated Administrator Connection

  Hi: I am trying to connect to my local instance of SQL Server 2005 using Dedicated Administrator Connection by using Admin:Servername\Instancename and I end up with the following error. Dedicated administrator connections are not supported. I enabled the connection in the SQL Configuration Manager and still get the error. Any ideas on how to resolve this error . Note: SQL Browser service is running. Thanks Ak You can check the sqlserver log to see if DAC is enabled/listening (and on which tcp port). Use sqlcmd -A to test. Also, you cannot use DAC for Object Explorer connection. It only works on query window. So, connect normally first, then open a new query window wi ...Show All

  I've got a custom class A that extends from ExternalDataEventArgs. That class has to include a class B that is not marked as [Serializable] then when I raise an event that uses A I get an exception.

• Visual Studio 2008 (Pre-release) WCF and REST based Web Services - Queries

  Hi All, I had been through the articles and blogs for .NET 3.0 (formerly Indigo and WCF). I have few doubts and need more info to get a head start on WCF.

• Visual Studio Express Editions sendinput code to perform sendkeys, keyboard events

  Anyone have a sample of code demonstrating how to set up sendinput Documentation is poor at best. There are a few samples on web, but are incomplete and despite tinkering can not get them to work. I read sendinput will be the best method to learn with vista coming, as sendkeys etc wont work well with it. So any help appreciated. I understood initially that the receiving program 'field' would be a richtextbox. The revised code should work for any richtextbox that last had focus when that program (the receiving program,) last lost focus. Just add ALL the handles of the richtextboxes (Fields) to the 'list' of handles in the revised code. When the sending program sends the 'trigger ...Show All
