• Beetlebum Making properties values persist in a workflow

  Hi. I have a application in wich I embedded a WWF Designer, where I add some custom activities.

• Sarath25177 Building Communication Interface between Host and Windows Workflows

  A workflow can be simply defined as a set of activities which execute sequentially or in parallel. While designing workflows for real-time scenarios, one of the common requirements encountered is the communication between workflow and the host launching that workflow. One of the ways of establishing a communication between the host and workflow is by using the runtime services provided by WinWF (WorkflowRuntimeService). ...Show All

• Robert Schneider 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

• lester1111 DirectUser API documentation

  Will the DirectUser API (in duser.dll) be documented with Windows Vista At first, I thought of it as a "stopgap" API--used only a few places in XP, and something that would be going away with the introduction of Avalon. However it seems that Vista isn't using Avalon for any of its own UI but is making even more pervasive use of DirectUser.  From the task dialog, to extensive use in control panel, DirectUser is something that Windows itself ...Show All

  I am timing the different aspects of WF execution and found one strange performance issue when starting a workflow. I have a simple workflow with three sequential code activities with only one print statement in each. I start many instances of this workflow in a loop from the main program (Program.cs). I measure the time just before I start each workflow (using workflowRuntime.StartWorkflow) and then pass in that time as a parameter to the work ...Show All
