• Software Development for Windows Vista WorkflowPersistence simple question

  Hi there, I'm writing my own workflow persistence service to support another database. I have following two save methods to override in my service: SaveCompletedContextActivity(Activity root) SaveWorkflowInstanceState(Activity root, bool unlock) The question is quite simple, how do I find in these two methods when I need to INSERT workflow record in database and when I need to UPDATE workflow record in database I can't find any boolean flags on Activity object indicating that this instance was already persisted. Looks like I've found a good solution... Just need a confirmation from MS guys. ...Show All

• SQL Server Concurrent Insert and Update Commands

  Hi there, I've had a look at this thread - http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=104399&SiteID=1 - but it's a bit old so I thought I'd try to clarify a couple of things.

As stated in the previous thread, when these commands run concurrently issues arise with blocking etc. The only way I've managed to get around it is by setting the access mode of the insert to OpenRowset. So 2 questions: 1) Does anyone know how this problem occurrs and w ...Show All

• Windows Forms Combobox problem

  Hi All, I have a combobox and a text box. They are both databound to different fields of a datatable. The combobox contains a list of telephone number descriptions eg. Home, Mobile, Work.
