• Tort Why is the Activity ContextGuid not public???

  The execution context of an activity is an important piece of the workflow. So why is this important piece of information hidden Currently, there is no way for me to correctly obtain a specific instance of an activity. The main issue I am running into is with tracking. I need to track additional information that is supplied by custom activities. Also, can see the need for a workflow to be able to access other activities in a specific context in order to complete. you can do this : Guid contextGuid = (Guid)activity.GetValue(Activity.ActivityContextGuidProperty); Nate Garvey wrote: Ok, so that helped with the first part. Now another problem. When I try to find a specific acti ...Show All

• slickred Web Service Host - CookieContainer Property

  Hello everybody, I just read an article where Israel Hilerio posted the example " Deploy Distributed Business Processes With Windows Workflow And Web Services ". It works all fine and I think this is a very good example. But I do not really understand how the WorkflowInstance is stored when he wrote the following lines of code: string workflowInstanceId = this .ListBox1.SelectedValue; System.Net. Cookie cookie = new System.Net. Cookie (cookeyKey, workflowInstanceId, "/" , "localhost" ); cookie.Expires = DateTime .Now.AddMonths(1); cookie.Value = workflowInstanceId; ws.CookieContainer.Add(cookie); I read that a HttpModul inside the Web Service stores the actual Workflow ID in the Http ...Show All

• ercan_06 Scaling out Windows Workflow

  Looking for a point in the right direction for scaling out an windows service hosted workflow to multiple application machines. In the MSDN article "Performance Characteristics of Windows Workflow Foundation" http://msdn2.microsoft.com/en-us/library/Aa973808.aspx they show workflows running on multiple machines. Are these machines sharing the durable queue thank you adam Tomas, thanks. Can the developer have explicit control over that Can we put "scalability" unload points into our workflows Also, I guess this means that I have to have the runtime started on n machines. How is the workflow "reloaded" automatically onto any of those machines after it has been "unloaded"   Than ...Show All

• PrashanthBlog Compilation error

• kinny_k Problems with Web folders (WebDav) in IE7

  Hi, I want to access a web folder with my IE, using a link in my portal. It seems like MS changed the way Web Folders work, since it doesn't work with IE7. whereas with IE6 it works perfectly. IE doesn't open the web folder and I get a "My Computer" window opened instead. I managed to bypass this behaviour by openning the Web Folder in an IFRAME, but still when trying to open a directory inside I get the same "My Computer" window. Please advise how to solve this issue. I have the same exact issue - IE can not open web folder - would you like to see the default view instead No - I want to open the folder not browse the website. Is there any fix for this Even with Offic ...Show All

• Prabagarane VNC and Session 0 Isolation

  Hello, I am the author of Bozteck VNCScan Enterprise Network Manager . I am a bit concerned about the new session 0 isolation in Vista. When VNC is installed to a Vista computer as a service, it is locked into running at only session 0 and that is pretty much useless for what it is designed to accomplish. In session 0, you can not remote control the computer or even get a remote screen shot of it. Our software is relied upon by over 100,000 Network Administrators across the globe and I have heard many of them voice deep concern about moving to the new Vista platform if VNC will no longer work properly. RDP is not an option because it does not allow the end user to interact with or view what the remote administrator is doing on their PC ...Show All

• Sergey Volk SqlTrackingService Beta 2 Lab 03 exercise 2 failed

  In WF hands on lab 03 ex 2, after I added the SqlTrackService, the workflow instance got aborted. I added event handler for ServicesExceptionNotHandled, it is not called.

• AugCampos WTSVirtualChannelOpen is failing for Vista

  Hello There, Need your attention on a small issue. WTSVirtualChannelOpen is failing and the GetLastErrorText returns “incorrect function” for Vista( RC2 and latest nov 17 ultimate release for developers). I tested this from both, 1. within an application in the user context, 2. as well as a service in session 0 on Vista. Fails in both the cases. This API returns a valid handle for XP / 2k3 and below. In Vista, as expected, the session ID of the application in which I use this call is Non-Zero. i.e. 2 or 3 or above. Whereas, in XP or 2k3 etc. the session ID is 0 because I run this application in the console session. Thanks, -dchawla. ...Show All

• cookieCutter Activity.DesignMode true when initializing the workflow

  Hi all I am working on a custom Activity which implements switch functionality. I am going to implement validations which involve Reflection to check if the case value suits the switched object (binded to a workflow property). So I don't want those validations executed on runtime. I tried to place the validation logic inside an if(validatedSwitch.IsInDesignMode) block where IsInDesignMode just exposes the protected activity property DesignMode. But it appears that prior to execute the activity, WWF initializes it and meanwhile the DesignMode property returns True. And that is when the validator is called. Any ideas how to distinguish the [real] design mode from this [fake] one would be highly appreciated. Thanks. ...Show All
