| What Happened to IPlaybackControl? (5 replies) |
| microsoft.public.dotnet.framework.component_services |
| I am porting a distributed VB6 application to .NET and have retooled my components as ServicedComponent descendants. In my original app I made a special exception class for a queued component this component implemented the interface of the queued class as well as IPlaybackControl (for FinalServerRetry and FinalClientRetry methods.) This prevented failures from collecting up in the deadqueue. Is th... |

| Problems with Sybase and COM+ (2 replies) |
| microsoft.public.dotnet.framework.component_services |
| Hi, We are developing a solution with .NET and COM and we have to integrate with a Sybase database. We write transactional serviced components. We use TransactionOption.Required and AutoComplete. This works fine for simple test cases where we insert rows into the database. Transactions are comitted and rolled back as expected. However, if we inside the same transaction (and same class) do a select... |

| This is a topic that has a lot of confusion wrapped around it. I am now thourhoughly confused about JITA, when and when not to use it. I see some doco saying that you don't need it, however I always wondered why Transactions requires it if you don't need it and the overhead is too great. If I have objects that don't require transactions, do I use JIT?? Why or why not!?!? Argh!! Does object pooling... |

| Shared Methods and Serviced Component (3 replies) |
| microsoft.public.dotnet.framework.component_services |

For example, This would work: dim oComp as new MyComponent oComp.MySharedMethod() But this would not work: MyComponent.MySharedMethod() I guess it makes sense because I read somewhere that the .NET framework sets up all the prec... |

| microsoft.public.dotnet.framework.component_services |
| Hi, I am trying to upgrade a COM DLL out of COM and into .NET. Back in COM , I was using Object Construction to pass config parameters into my object and obviously, this works differently in .NET. My understanding was that I would need to add a reference to System.EnterpriseServices which would enable me to inherit my class from ServicedComponent, so I could get at the Enterprise Services stuff.
