How do I load a instance of workflow persisted on database, I tried the following 


 private List<WorkflowInstance> m_ListaInstancias;
    public void ObterWorkflowsBD()

      foreach (SqlPersistenceWorkflowInstanceDescription inst in m_persistenceService.GetAllWorkflows())
        Console.WriteLine("id: " + inst.WorkflowInstanceId.ToString() + " status: " + inst.Status.ToString());

           WorkflowInstance intancia_bd = workflowRuntime.GetWorkflow(inst.WorkflowInstanceId);


    public void ContinuarWorkflow(Guid Guid)
      foreach (WorkflowInstance item in m_ListaInstancias)
        if (item.InstanceId == Guid)

Foundations: Windows Workflow Design Patterns


Design patterns provide a common, repeatable approach to solving software development tasks, and many different patterns can describe how to accomplish a certain goal in code. When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month's column discusses several design patterns used in WF.

State Machine workflows represent a different way of visualizing program logic. Rather than flowing from activity to activity like sequential workflows, State Machines transition from state to state.

MVC and Windows Workflow


I have an ASP.Net MVC application manages process of forwarding some business entities to one another partner.  At beginning of the process, the forwarding partner sends a request to every other partner.  There are many receiving partners for the forwarding request, but only the first partner who responds with ACCEPT token will enter into the contract with the sending partner.  When this happens, the process enters ACCEPTED state.  When the process goes into ACCEPTED state, the same request previously received by other partners will enter into Cancelled state.

I am thinking using Windows Workflow Foundation to do this, but I am not sure if I should use one flow or multiple flows associating with the forwarding request flow.  If multiple work lows are required, should they be all with the same structure, states, events, handlers, etc?  Any flow executes Accept method enters Accepted state, and triggers all other flows' Cancel events.

Can this be done?  Any other recommendation?  Thank you.

VS Studio WorkFlow Failed on Start in MOSS 2007 ON Windows Server 2008 64 Bit

2   i again tried this C prompt Lodctr /R "c:\Windows\Microsoft.Net\Framework\v3.0\Windows Workflow Foundation\perfcounters.ini"

it says reloaded  from the system restored

i am still getting the same error.

When i manually go to my  C:\Windows\Microsoft.NET\Framework\v3.0\Windows Workflow Foundation i can see a folder for SQL that's it nothing more than that..

Why to Use Windows workflow

Hi All, Could anyone please let me know some guidelines/best practise why and where to use windows workflow. We started our development using windows workflow 3.5 State machine for complex business process. Somethig which were not feasible in workflow we put the same in D/B. Later when we developed the entire solution we found WWF is an overhead. We can have easily developed the entire solution using Data base approach as we are so much dependent on Database.   Could any one of you please let me know what question/sceneraio we should look at , so that we can justify that using WWF is right. Right now we feel WWF is an overhead to ours complex State MAchine Business process. We can easily achive all requirement using Database approach.   Regards Robin

Unable to call an asmx web service using windows authentication from a Service workflow

Hello, I need to use an existing asmx service from inside my service workflow and I am unable to call it. This asmx service is hosted in a web application with iis set to windows authentication, anonymous is not allowed. I need to send the authentication, only way seems too be using transport for basicHttpBindings. Every time I try to call the service I get an error saying that there is nothing listening to the url of the service generated automatically by VS when I added the Service Reference ? my web config <configuration> <configSections> </configSections> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> <system.serviceModel> <protocolMapping> <add scheme="http" binding="wsHttpBinding" bindingConfiguration="WindowsCreds" /> </protocolMapping> <bindings> <basicHttpBinding> <binding name="UtilitiesSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"

Windows Workflow : Activity Binding Properties Window Ellipses button not visible for one property

I have created a custom activity, when I am using this activity in workflow designer I am not getting the ellipsis button to select a property.  I am getting the ellipses button for first property LongValue while not getting the option for "NavigationUrl" property. This is the code for my custom activity. public partial class SetLongAsResult: Activity {         public SetLongAsResult() { InitializeComponent(); }         public static DependencyProperty LongValueProperty = DependencyProperty.Register("LongValue", typeof(long), typeof(SetLongAsResult));           public static DependencyProperty NavigationUrlProperty = DependencyProperty.Register("NavigationUrl", typeof(string), typeof(SetLongAsResult));           [Description("long value to be returned")]         [Category("Set Result Data")]         [BrowsableAttribute(true)]         [DesignerSerializationVisibilityAttribute(DesignerSerializationVisibility.Visible)]         public long LongValue         {             get             {         

Suspend / Resume Instances within Workflow Service Host (in Windows Service)

We are hosting WF 4 worklfow instances within a Windows Service that uses the Workflow Service host container.   On the Windows Service OnStart we start the workflow service host (w/ multiple WCF endpoints such as start workflow instance, cancel workflow instance, poll workflow instance status, etc.) and these endpoints create or work on one or more long running workflow instances.     My question is, if a user attempts to stop the Windows Service while workflow instance(s) are running, what is the best way to manage this scenario.   Our inclination is to persist these workflows (using sql persistence) and then on the next start of the Windows Service, resume these workflow instances and allow them to continue to completion.    In OnStart, we have a handle to the Workflow Service host.    How can we iterate through all the active workflow instances in OnStop and then in OnStart, resume these after the workflow service host is opened and running?   Are there are any methods of managing this scenario?    Thanks
