• Visual C# Best Practice: Properties in the Constructor

  For some reason I remember reading that it is not considered best practice to set a Property within the constructor when there is a private variable associated with said property. It would be considered best practice to go ahead and set the private variable. Is this true for example: public class MasterItem : Item { internal MasterItem( int facilityId ) : base ( null ) { this .Facility= ( Facility )facilityId; } protected Facility facility; public Facility Facility { get { return facility; } set { .... facility = value .... } } } The issue is that I have more going on in my set method of the property that I need to be run when the facility is set via the constructor.

• SQL Server Blocked transaction problem

  Hello, I am trying to execute next query, but when doing it, TABLE1 locks and it does not finish. SERVER2 is a linked server. BEGIN TRAN INSERT INTO TABLE1 SELECT * FROM SERVER2.DATABASE2.DBO.TABLE2 WHERE TAB_F1 IS NULL COMMIT TRAN I have same configuration in other 2 computers and it works ok. What is the problem Thank you!! Hello, I can not see anything because the execution of the query never ends. I leave up to 30 minutes and it does not end. I can execute the query without a transaction and it finishes in a few miliseconds. So, it is posible to query other server. Could it be a problem with server names I mean, the name registered at SQL Server Enterprise Manager, the o ...Show All

  I have a Xbox 360 wireless remote with the usb adapter I was wondering if I could use it for xna games on PC. If so how would I go about doing it thanks The Wireless 360 controller is not currently supported under Windows.

• SQL Server Visual C++ 2005 (C++/CLI) - Newbie with ADO

  Hi, I've been working for about 20 years now with databases on other platforms but am at my first step with ADO. I created an application which is drawing as requested different forms on screen using GDI+, eventually DirectX. Now I'm at the stage of saving several infos into a Database. For simplicity, I would like to use a database for which there is no need to install any other components. I thought of using Access Database but I realized that I'm unable to create it except from Microsoft Access which is not installed on my machine... When programming with Clarion (SoftVelocity), apart interfacing with Oracle, any other files (ex: TopSpeed files) could be designed from within application designer and then created from scratc ...Show All

• Visual Studio Express Editions How do I (is it possible) to change the ListBox properties?

  Greetings, Is it possible to permanently change the properties setting for a ListBox What I would like to change is : Every time I start VB express (IDE) and I drag a ListBox from the Toolbar to a Form that the default property for the ListBox SelectionMode be set to "MultiExtended" and not "One" as is at current.

• Software Development for Windows Vista Communication with external applications

  Hello, I've been trying the hands-on labs and now I'm developing a simple workflow myself, but I don't really know how to communicate between an external application and the local workflow. I know that lab05 deals with a similar topic but I've found that the communication was only between a LOCAL application and the workflow but not with an external application. Now I'm trying to follow the expense reporting application in lab01 (resources folder) and I try to see how it communicates with the workflow. I've seen it uses .NET Remoting to create an instance of the remote class, but I don't get to understand well what it does because the same project has together the remoteservices class and the localservices class.
