    What if an exception is thrown in the background task?

    mcnamaragio, The MSDN documentation for the DoWork event describes what happens if an exception is thrown: http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.dowork(VS.95).aspx Hope this helps!

    Hi, I've been trying to make a reusable background worker close to the one you show here. Your work looks good and I've learn from it, the obvious down-side is that your class is singleton and so can only be one instance in the whole system. You might want to have different section of your system have independent background task management. Also you left out the exception handling. Thank you, Ido.

    Thanks for the feedback, Ido! It's always great when people are able to work off of each other's ideas to come up with even better things! :)

    Hi, I'm wanting to include a BGThread manager in my VB.net code, and I'm having issues translating your class to VB.Net.. Specifically the following...

  1. public static EventHandler<EventArgs> BackgroundTaskStarted;
  2. var backgroundTaskStartedHandler = BackgroundTaskStarted;        if (null != backgroundTaskStartedHandler)        {            backgroundTaskStartedHandler.Invoke(null, EventArgs.Empty);        } I would appreciate it very much if you could supply a vb.net equivelant..

    Grant, I'm on vacation and don't have a compiler available at the moment - however, maybe try something like the following to get started:

Public Shared BackgroundTaskCompleted As EventHandler(Of EventArgs) 2. ' Invoke the BackgroundTaskStarted event Dim backgroundTaskStartedHandler = BackgroundTaskStarted If backgroundTaskStartedHandler IsNot Nothing Then    backgroundTaskStartedHandler.Invoke(Nothing, EventArgs.Empty) End If If that doesn't help, maybe try one of the many VB.NET/C# code translation tools on the web. Thanks!
