• RFabian 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

• Sagar-1 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

• Pike SqlTrackingQuery comments and questions

  I've just installed beta 2, and I'm glad to say I find things much more robust in general, and somewhat faster (though the fact that I got a new machine might have something to do with it ). Anyway, I've been checking the new SqlTrackingQuery facilities and I gotta say it's very nice to have something like this; it really seems like it is something useful in building more robust implementations and providing tooling for problem diagnose and stuf ...Show All

• Shobha69358 Properties Window Suggestions

  The web form and Windows form designers allow me to double click (or press enter) in the text box for an event. The double click will take me to the code-behind, generating the event handler if it doesn't already exist. It feels like the WF Properties window isn't working correctly when I double click in a handler like ExecuteCode and nothing happens. (I do get the "right" behavior if I double click the CodeActivity itself). The ...Show All

• chris.p Can't see filter in graphedit

  I've taken the directshow ball sample filter and made it a dll. I've edited the AssemblyInfo.cpp file and run sn to generate a strong name, then run gacutil -I to install the dll in the GAC. Can't see the filter in graphedit. Something I'm missing The GAC has nothing to do with GraphEdit. What would make you think that putting things there would cause them to show up in graphedit If reading the samples does ...Show All

• Ivan Budiscak Journaling hooks on Vista?

  Along with a lot of other people, I've noticed that attempts to set the journalling hooks ( WH_JOURNALPLAYBACK, WH_JOURNALRECORD) get knocked back with access denied on CTP 5270. Is this down to the new Vista security policies MJTNET wrote: Update - changed the manifest slightly. This time no "access denied" error and the exe started, but the original problem persists. :-( I dis ...Show All

• Junz Binding in XOML only workflows?

  Tom, I have converted a State Workflow to XOML only State workflow. It seems that the HandleExternalEvent activity does not set OrderSender object to a value. As a result sender parameter is null, but the e parameter is not null. This was not the case prior to converting the State workflow to XOML only workflow. Please review the XOML syntax and let me know if the binding syntax for OrderSender is not correct ---------------------------- ...Show All

• Moorstream Calling into an instance through a web service

  I've got a workflow exposed as a web service, hosted inside ASP.NET. The workflow contains a Listen activity with two branches where one of them is a WebServiceInput activity. I got a couple of questions related to this second WebServiceInput activity: How can I control the correlation from the WebServiceInput activity into the right workflow instance When will ASP.NET start listen on behalf of the WebServiceInput endpoint How can I set ...Show All

• Jong8282 using WWF with SOA

  I need to take some advice from the Architectural community out there, as much of the discussion to date appears to focus on an application hosting the WWF engine and exchanging events in a fairly self contained fashion. Scenario Consider...   Many instances of a windows forms client application communicate with a server application via web services. Traditionally the server side business logic contains set workflo ...Show All

• hhampa State machine WF Quandary

  Hi, I'm chomping at the bit to implement WF, but in need of a few high level pointer when it comes to design. I intend to implementing a State machine WF into a typical n-tiered asp.net app. I have a "Supplier" object that can have various states. As a Supplier's state changes, Email notifications are sent. Pretty simple. The catch is that the make up (body, subject, etc) of the email itself is driven by; the stat ...Show All

• Anand Kalyanam Does WWF 2.2 persist the detailed layout information into the XOML file?

  In Beta 1, the detailed layout information for the state machine workflows was persisted in the Visual Studio .SOU file and not in the actual XOML workflow definition. Has this been fixed since Beta 1 ...i.e. in Beta 2 or Beta 2.2 If not, what are the plans for addressing this Michael. The layout gets stored in the .layout file now (since beta 2 I believe, but definitely in beta 2.2). Matt Thanks Matt, Is this an XM ...Show All

• Helixpoint StateMachine: HandleExternalEvent vs. WebServiceInput.

  I need some direction for the users of this forum. I have a state machine workflow, when the workflow reaches the VerificationPending state, it waits for input from other systems. In the VerificationPending state, I have 2 event driven activities, and both activities use WebServiceInput activities to transition to the next state in the chain. The possible states after VerificationPending are Hit or Cleared. So, in summary, If the Web ...Show All

• Giv Afshar /workflow, /self and /parent

  Hi, can somebody please explain how to use /workflow, /self and /parent within dependency properties. Cannot find any documentation. Also, I'm trying to "autobind" a property of a custom activity in its constructor, using /worflow (so that a workflow designer does not have to set properties) but this seems not to work. Is this possible in some way Thank you very much. Martin /Self is used when the v ...Show All
