• Shailesh Paranjpe Breakpoints not working

  I'm running the February CTP on WinXP SP2 and Visual Studio Pro. I'm running my development environment inside of a Virtual PC VM. The problem that I'm having is that I can create workflows fine, but breakpoints set up on a workflow activity do not work. I see the hollow circle with the warning when running in debug mode. Breakpoints set on the code beside code such as a CodeActivity handler work. I've looked at the other posts on the foru ...Show All

• Imran Farooqui Why just HTML and JavaScript support for The Windows Sidebar Gadgets?

  I got really disappointed when I saw how Gadgets work and how to develop them. Gadgets are developed using HTML and JavaScript. You can find more information about how to develop Gadgets and how they work here http://microsoftgadgets.com/Sidebar/DevelopmentOverview.aspx . I remember watching a video from PDC 2005 about Windows Sidebar development right after the PDC event. I learned about the Windows Sidebar visions and one just got stuck ...Show All

  Has anyone encountered a problem where their disply gets greyed out right after login It has happened a couple of times to me. The brightness and contrast are fine at login, and then as soon as I login everything except the cursor gets very dark to the point of almost being completely black.

• Rodi Problem creating a parallel version of the ForEach example activity

  I am trying to create a custom activity that is similar to the ForEach example posted in the custom activity gallery: http://www.windowsworkflow.net/ControlGallery/ControlDetail.aspx Control=2222&tabindex=2   The code below is basically modifications to that sample (i.e. the activity inherits from CompositeActivity, etc.) The difference is that I want the set of activities executed to be done in parallel rather than serially ...Show All

Now when I raise the ScanEvent with the same instance ID i get an error EventDeliveryfailed for the instance ID.. When I look in the innerexc ...Show All

• Johnson Maynopas 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 Well, it's the same in the Feb CTP, 5308 - which is supposedly feature complete. Please can someone from MS tell us definitively whether we have to start recoding our software i ...Show All

• Maik Duwi ASP.NET And a State Machine Workflow

  I recently read the MSDN magazine article, Windows Workflow Foundation, Part 2 (http://msdn.microsoft.com/msdnmag/issues/06/04/CuttingEdge/), where Dino Esposito demonstrates how to work with workflows in ASP.NET. Dinos' demonstration provides a helpful solution to working with Sequential workflows; however, it left me a little confused with how to work with a State Machine workflow. In the article, Dino demonstrates how to pass parame ...Show All

• Aero.NET Multi-Modal activities and workflows

  Has there been any thought given to multi-modal activities and workflows As an example, we may want to create a workflow that could run as a desktop application or on our IVR (phone) system. Such a workflow may begin with a Login activity that presents a login dialog on the desktop or prompts the user for a pincode in the IVR. So far, I have only come up with one good approach. It involves pairing somewhat generic activities with well-known ...Show All

• assssssss FlowChart workflow - Custom FreeformActivityDesigner sample

  Hi,        Here is the long due sample for writing custom activity designers utilizing the freeform activitydesigner. This is still a very crude sample, so we will try to post improved versions from time to time.  Thanks to Arjun for the Executors and Validators. The validators show a false positive sometimes because of a bug that we will be fixing soon. http://www.thispointer.com/workflows/FlowChart.exe ...Show All

• Stephan Ruhland PersistenceService in WebFarms and NLB

  I implemented asmx web service that hosts workflowruntime with SqlPersistenceService. WorkfowRuntime hosts StateMachine workflows, that have eventdriven events with delay activities inside. Asmx web services are hosted in iis on multiple machines on nlb, and they all use same persistence database. My question is what will happen when workflowinstance goes idle and waits for delay activiti Is it possible that problem occurs when all web ser ...Show All

• D. H. Scheduling Activities

  Let us assume we have "SendMail" Activity. I wanted to send a mail on every sunday to some person(say abc@xyz.com ) how can we implement such scenario in WWF Two quick choices come to mind: 1) Create a workflow with a while shape that loops endlessly. In that loop put your send mail followed by a delay. For the delay, set the timeout based on the difference between now and your scheduled ...Show All

• PDADev SDK compatability with VS2005 RC

  First of all, the software looks great. The time and dedication is evident with the thoroughness of the design. Currently, we have our own proprietary workflow engine and were about to look at re-envisioning our designer as a DSL. With this announcement, we will have to re-evaluate our position.  We have a few guys at PDC this year and they have been very impressed with the demonstrations and labs (I just had to pick this yea ...Show All
