Under ASP.NET I raise the same event (same code in same DLL) I get the error below. The ASP.NET code raising the event is this: ASP.NET Code: '...Get the GUID of the task Dim ID As String = Me.GridView1.SelectedRow.Cells(4).Text Dim ins ...Show All

• khkassem web service workflow

  I've asked this before in one of my previous posts but it got buried under and can't get the answer. Here it goes again. 1. I've followed AddService using in the book. Seems to be clear. The problem I'm facing is that my next activity happens day later, unlike in AddService scenario where webservicereceive is followed by webservicerespond immediately. How does the host (iis ) brings in serialized workflow instance into the memory and what trigge ...Show All

• gdillen If you have trouble installing the Windows SDK...

  If you run into problems installing the SDK, there are a few common culprits. Click the Log button on the "Install Complete" screen and open the log. Or browse to your %temp% folder and open sdksetup.txt. Scroll all the way to the bottom, because that's where the error will appear. One frequent problem is with Microsoft Document Explorer 2005 in the log. For instance: 10:45:37 AM Tuesday, January 24, 2006: [SDKSetup:Info] Config_Products_I ...Show All

• Maddytk Rendering a stream

  Hello everyone, I'm really new in directshow development, and I hope you will be able to help me.

• Dedy Susanto Deriving Workflow classes...

    Hello, if I want to derive a class from SequentialWorkflow and then define new workflows from this derived class. When I change the base class in the partial definitions of a code workflow to my derived class it works, but when I define it using xoml there is a problem with some partial definition of the new workflow. Is there any way to resolve this example: public partial class Workflow4 : MySequentialWorkflow erro ...Show All

• 0x00 Dual Display Suggestion

  Hi, I use dual monitors for work every day, and the most annoying thing you can imagine is when I am several programs open and it seems like every time I open another window, it opens one the opposite screen that I want it to.  Perhaps microsoft could come up with a way to right click a shortcut and press "open on screen 1, 2, etc." or maybe when you double click a program and move the curser to the screen you want it will automatically ope ...Show All

• Samarth04 Workflow compiler error: "Attribute 'Class' not found on the root activity."

  I have a console app that programmatically builds a workflow. It creates a sequential workflow object, adds activities (implemented in a separate DLL) to it, serializes the generated workflow definition to a XOML file,  compiles the XOML definition to an assembly (DLL), and executes the workflow (we are building a prototype here, so at this point everything is done within one program). It seems to work, but there is one ...Show All

• Deepak Manchanda WF custom persistence once again

  I don't want to save my workflows zipped in a blob field in one table like default SqlWorkflowPersistenceService does. It is not transparent and flexible approach, saved data contains class type information, making workflow evolution almost impossible.

• akks DependencyProperties backed by another properties?

  Hi, I'm thinking about wrapping some legacy components as WF activities. Let's assume that I have a bunch of classes, each having a Run() method and a couple of properties. The usage pattern is very simple: set the properties and (assuming that IsConfigurationValid() returns true) call Run() which will do some operation: abstract class Worker { public virtual void Run(); public virtual bool IsConfigurationValid(); } class TestWorker : Worker ...Show All
