• LarryWho Requiring Parameters

  I am writing a collection of activities that will handle all aspects of dealing with different objects like employees, accounts, etc. The goal is to give the application developers these activities that they can plug into their workflows. For example, I have a DisplayEmployee activity that contains a form and validation logic. I also have a SaveEmployee object that knows how to persist the employee information to a data store, creating the emplo ...Show All

• lx_aka_alex WinFX Crashes

  OK. Just installed the November CTP's and installed all of them. Everything seems to "work", but I can only get the WPF samples to run about 1 in 5 times - and when they do run, they crash very quickly. Almost all of them do this, no matter how complicated they are. Such as, when I run the "sample viewer" app, sometimes it will actually start up just fine, and I can start to navigate around.  But usually within a minute or so (or a bun ...Show All

• Victor Lu Custom activity based on HandleExternalEventActivity

  I would like to create a custom activity that responds to external events and then executes a sequence of activities. I initially created an activity derived from a sequence and added my HandleExternalEventActivity at the start of the sequence. However, because sequence does not implement IEventDriven I can't add it into an EventDrivenActivity sequence and therefore can't use the Listen shape to respond to my external event or something else. ...Show All

• BobIves Stateless Hosts

   I understand that the WWF engine must be hosted in a host.   When using ASP.NET I assume on the page load the workflow is loaded, work is done, and then the workflow is saved and persistated to disk. What happens when you have asyncronous operations   Does the workflow engine stay alive until the async operations are completed While ASP.net is statelesss, there is still an active host and the application domain for a ...Show All

• Scott Berry Compact Framework

  Well, I think I already know the answer to this question, but I'm going to ask anyway: Are there any plans now or in the future to support workflow on the Compact Framework As I'm sure the team is already aware, CF support would be highly valuable for process automation in refineries, pharmaceuticals, power generation and several other vertical markets. Sure James.   At a recent job, ou ...Show All

• JuanVali Playing WMV10 through DirectShow?

  It appears the default codecs only support up through WMV9 and when playing a WMV10 hd file, they don't fully decode with a DirectShow application. Are there DirectShow filters for WMV10 or is the only option to embed Media Player 10 through its SDK Found it.  It appears the default source filter's merits were some how changed or corrupted and DirectShow was using an older source filter.  Media Player apparently loads this filte ...Show All

• MonuReddy Cluster-Aware Timer Service

  I'm curious to see if Microsoft (or other developers out there) can provide guidance on how to best develop a custom Timer Service that is web farm aware.  For example, let's say my middle tier workflow is running on 3 servers.  I have a custom Timer Service running on each server but I obviously don't want the same workflow *instances* to be monitored and executed simultaneously on each server in the cluster. I've seen some tantali ...Show All

• LK440 WWF Performance issues

  I am doing some timing measurements to figure out whether we can use WWF for orchastrating code within our project. Here are some of the numbers I am getting and questions associated with them: 1. For a workflow with about 5-6 activities including a parallel activity and several code activities, the time to create the workflow the first time is more than 300 millisecs (328, 359, etc). All subsequent times it takes about 15 millisecs. What i ...Show All

• Mehmet Ali Ekingen 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

• Sans103171 Error adding a custom activity to a workflow

  I defined a new custom (composite) activity as part of a workflow activity library. The library project compiles fine. From within my sequential workflow project, I add this activity to a workflow by dragging it from the toolbox in the designer. I define the required parameters in the workflow that the above activity expects. However I get following error while compiling the workflow project.
