• MadMojo1 Xaml Activation :: Passing data from one activity to another

• Luis Esteban Valencia MCP. custom EventDrivenActivity? custom Replicator?

  Is it possible to create a custom EventDrivenActivity The goal is to have a StateMachineWorkflow where a user can directly drop this custom activity into the state, set the event to wait for and the resulting next state. This would ease the state machine development for him by far as he does not have to create the event driven activity, the event handler inside, the set state event and get out of the state designer again. Is it possible somehow As one cannot inherit from the EventDrivenActivity is it possible to replicate it's behavior by implementing the right interfaces or something like that Is it possible to create a custom Replicator like this I want to take away the burden to initialize the replicator elements from the g ...Show All

• Mike Chapman Inconsistent File System Enumeration with FindFirstFile / FineNextFile

  I'm working to get a commercial application to run on Vista. Among the many broken things, the first one I encounter is a crash due to a stack overflow due to a recursive function that goes bad. The app enumerates files in various places using FindFirstFile | FineNextFile in a recursive function (C++). I'm using retail Vista Ultimate with VS 2005 sp1 plus the VS Vista update beta. What I see in the debugger is that when I start out enumerating drive "c:", I come to the "Documents and Settings" folder and recurse into it. When I get to "c:\Documents and Settings\All Users\Application Data", FindNextFile then returns "Application Data" over and over again and I recurse into "Application Data&qu ...Show All

• Haldox Asp.net 2.0 hosted workflow is firing events triggered by delay activities later than expected

  Dear all, I have a state machine workflow hosted under asp.net 2.0 which uses the ManualWorkflowSchedulerService, as recommended. It also has persistence and tracking running, with UseActiveTimers = " true " , so that expiring Delay activities wake up the workflow and continue execution. Generally, this all works fine. I have put up a test version of the web site and asked a colleague to test it across the internet. We were mystified by the fact that certain events which should have taken place when a Delay expired at a specific time actually took place much later. I have now realised that the expected events do not fire because the web site has "gone to sleep" because nobody is accessing it. The events g ...Show All

• peansen Third year College project

  Dear all, I am a college student over here in England . I am doing my third year project and have chosen “The identity metasystem” as my subject area. It all started in the summer when I did some work for Marcus Lasance at Maxware UK . I was doing a little research project into identity cards. At the time I was also tiring to work out what to do for my final year project. I then decided it would be a good idea to use my college, Suffolk College , as a case study that would form the basis of my project. I’m just stating now, so I’m at my proposal stage. I am panning to get a new notebook with Vista on, so I can create some cards and hopefully a dummy relying party website I would also like to be ...Show All

• nikos_22 Vista Media Center report "Video Error"

  I am working on TV Tuner driver developing. I  tried to hot plug the USB TV Tuner when Media Center is playing and the Media Center shows "Video Error" and stopped. Then re-pluging the device and choose Media Center live TV, Media Center restarts Playing. But if I tries to re-scan channel at that time, Media Center will hang in the scanning process.  I analyzed the message from my driver, it worked to change channel and send data to AP. I also tried other TV Application but no fault with them. Media Center will become normal after restarting the PC. Does anyone meet the situation What will make Media Center to show "Video Error" ...Show All

• Chuck Catron WPF/E - Embedded JavaScript/HTML

  Hello, Is there a way to embed JavaScript or HTML within a .xaml file I played around with CDATA and didn't have any luck. If not, could it be possible to add a parameter to the WPF/E container object that allows developers to point to a custom .js file No - there isn't any way to embed script/javascript into XAML content that "WPF/E" can recognize. You might go a more XML approach and generate your own XML schema that has XAML content that you can pull out and use in a createFromXaml call. Regarding custom .js file -- the biggest issue around this is dealing with namespace conflicts (you have a function/class named foo in your custom .js file that is also definded in the HTML page scri ...Show All

• Liam404 Is Sequential workflow can be a base workflow and can we access methods inside that by inheriting

  Hi, I am trying to acheive Pure XAML in ASP.Net. The steps in my work 1.

• JasonG271009 regarding invokeworkflowactivity based on xaml

  Hi, How can I make the InvokeWorkflowActivity call a child workflow that is XAML only state workflow I used the following code snippet instead of invokeworkflowactivity IStartWorkflow aWorkflow = executionContext.GetService( typeof ( IStartWorkflow )) as IStartWorkflow ; Guid guid = aWorkflow.StartWorkflow( typeof ( SampleWorkflow1 ), parameters); Here StartWorkflow takes workflow type as argument. How can I use the XAML only file Take a look at this post for more info. Hi, As far as I can tell there is no standard way supplied to do this. To do this you will need to create your own IStartXomlWorkflow service with a reference to the runtime so you can start them. Maurice ...Show All

• Jegant confirmed bug in delay activity

  Everyone, I just wanted to let anyone who is battling the delay activity know that buried deep in the sharepoint team's blog, is a comment that confirms the bug. My experience is that the delay activity works fine until an object is persisted to the database. Once persisted (dehydrated), the delay activity doesn't cause the object to rehydrate. http://blogs.msdn.com/sharepoint/archive/2006/11/30/developing-workflows-in-vs-part-6-deploy-and-debug-your-workflow.aspx#comments the 3rd from last entry from Eilene Hao (a member of the Sharepoint team). # re: Developing Workflows in VS: Part 6 - Deploy and Debug your workflow Hi guys, there's a bug on delays at the moment; we're working on a patch that's almost ready. ...Show All

• NeederOfVBHelp Tracking Query returns null

  I have update the Workflow Foundation from the Beta 2.2 to the RC1. In the RC1 there is no "SharedConnectionWorkflowService" anymore. It is called "SharedConnectionWorkflowCommitBatchService" now.

Since that I get an error in following code statements: SqlTrackingQuery sqlTrackingQuery = new SqlTrackingQuery (ConnectionStringWorkflowService); SqlTrackingWorkflowInstance sqlTrackingInstance; sqlTrackingQuery.TryGetWorkflow(e.WorkflowInstance.InstanceId, out sqlTrackingInstance); The method "TryGetWorkflow" doesnt populate the SqlTrackingInstance. It is being null. Before changing the Shared Connection Service it worked. Any suggestions, where the problem may be Thanks ...Show All

• Markward Application.ExecutablePath and non-english characters doesn't works in Vista

  Hi experts. I have a Windows Forms application that makes an initial call to Application.ExecutablePath() . It is based in .NET Framework 1.1 and it works in Windows 2000, XP and 2003. It doesn't works in Windows Vista because this function returns strange characters with non-english characters in the path or EXE name (like "c:\Aplicaci o n\Aplicaci o n.exe"), and these characters are replaced by a square character. In the .NET Framework 2.0 I have the same problem. However, if I make a call to Application.StartupPath() , I get the path correctly, but I can't change this call and recompile it in all versions of the application. I think there is a problem with the .NET Framework and Vista itself, so I will appreciate ...Show All
