• mischa123 How to determine state of state workflow?

  Hey guys, I'm developing a state workflow. As it is good practice I'm writing unit tests to test the correct behavior of the workflow. The problem is that so far I couldn't find out how to get information about the current state of a workflow, whether it's waiting for an event, etc. I have the runtime object and a workflow instance, but none of these objects exposes properties or so to get this information. Also, I'd like to pause the u ...Show All

• Anders Lillrank Quicktime and directx

  I am trying to figure out how I can extract single frames one by one from a quicktime movie and load them as textures. Apple has a lot of info, but aparently not anything about extracting frames. Is this something that directx can handle. Perhaps through a plugin I was looking at using directshow to render to a texture and then use it, but aparently this can not be done with quicktime movies Hi Thomas. I've t ...Show All

• ssfftt Binding CodeActivity.ExecuteCode to method in custom StateActivity

  Hi all I'm using a State Machine Workflow to model an event-driven system. My current issue is that all workflow state (properties, fields) must be persisted to the parent StateMachineWorkflowActivity. This is not ideal for compartmentalising functionality. I'm trying to work around this by using custom StateActivitiy's which store state in private fields (exposed via public methods). I can use dependency property binding to bind to these ...Show All

• glentrino2duo Designer and the Toolbox

  We are working on integrating the workflow desinger into our suite of tools. Our shell currently has a toolbox that implements the IToolboxService interface. When we create the DesignSurface for the Workflow designer, we pass in our root service provider (which contains our toolbox service). However, the Workflow designer never asks our service provider for the IToolboxService (though it does ask for many other services). How does the list of av ...Show All

• LMcFarlin Beta2: String-Properties in Custom Activities; Custom themes

  Hi, in Beta 1 it was possible to define 'free text'-input string properties with custom activities which enabled the workflow creator to input any text in the corresponding prop of the activity in the workflow designer. Any DependencyProperty with type(string) enabled this. In Beta2 this definition enforces a total different behaviour in the Workflow Designer - it tries to map it to a Workflow member variable ...

• Chris Baldwin - MSFT "Tracking workflows which are already tracked" - Problem

  Following screnario: I have business objects of the type Order and OrderItem. For each of these a workflow is started. I use the SqlTrackingService, so running workflows get written to the db, and I am able to track them with the WorkflowMonitor (included in the Windows SDK I think). If such an Order- or OrderItemWofklow gets aborted or canceled the chance of restarting the workflow with the same objects is still present. The only problem ...Show All

  I have implemented a custom WorkflowScheduler to give me control over threading. I am running into issues with timed activities. My sample workflow has alternating code activities and delay activities. When I reload the workflow after the delay has expired, a call to my scheduler service is made to schedule the workflow with timer information. A second call is also made to schedule the workflow without timer information. This causes the ...Show All
