• Steve Perry Inheriting from StateMachineWorkflowActivity

  Hi all, I'm wanting to supply all child state workflows with common props + methods. I'm looking into inheriting from StateMachineWorkflowActivity. All goes well except....(there's always a 'but') 1) when creating the 'parent activity' - e.g. class CoreWorkflow : StateMachineWorkflowActivity That project wont compile as it needs an initial starting state. I've tried a few fudges that 'sort of' work - but nothing I feel confident with ...Show All

• NaturalInterface Problems with state persistence and timer services

  Hi, I've experimented with adding the SQL state, timer and tracking services to the Lab1 sample step 4 (the expense report approval workflow). The tracking service works fine, but it seems that the state and timer services get the engine stuck on the ListenForManagerApproval activity. If I disable the state and timer services the workflow unfolds as expected. I use the (really cool) Workflow Monitor sample to view the results, and the progress ...Show All

• Michael Kariv ASP.NET And a State Machine Workflow

  I recently read the MSDN magazine article, Windows Workflow Foundation, Part 2 (http://msdn.microsoft.com/msdnmag/issues/06/04/CuttingEdge/), where Dino Esposito demonstrates how to work with workflows in ASP.NET. Dinos' demonstration provides a helpful solution to working with Sequential workflows; however, it left me a little confused with how to work with a State Machine workflow. In the article, Dino demonstrates how to pass parame ...Show All

• John UK How to troubleshoot custom designer for sequential workflow

  Hello, In the post http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=160891&SiteID=1 , Arjun describes how to define a custom designer for a sequential workflow.  As noted in that post, I've tried to imitate Arjun's steps but my custom designer does not appear to be loading.  I'm reposting the following to hopefully get some visibility: I've tried overriding the HelpText and ShowSmartTag properties but I don't see any change to ...Show All

• Andray Siletsky Service events missing event handlers? - [code included].

  "In Beta2, when you add a service to the ExternalDataExchangeService, the events are assigned event handlers that, when invoked, enqueue a message onto the workflow queue created by the HandleExternalEventActivity." I'm not seeing my HandleExternalEventActivity getting invoked and I believe it might be because the initialization step in the workflow creation is not creating these handlers for me. So my event sin ...Show All
