• Alex Bocharov Accessing properties of the Host from within an Activity running in a Workflow

  I want to be able to access a public instance property of the object that's hosting the Windows Workflow Runtime, from within a custom activity. I want to be able to, via the Designer, set the name of the property I'm retrieving from the Host (I don't need design-time support really - just a normal string identifying the property name will do). To do this, I know I'll need an instance of the Host. Is this possible If not, is there some oth ...Show All

• Rocinante8 WWF and ASP.Net

  Any news on how WWF will integrate with ASP.Net I am hoping that it will provide a way to graphically manage the workflow of an ASP.Net application. It always bothers me having to bury navigation instructions in your code - if WWF can improve on that then please let me know!! Sorry for misleading you. That area of the docs is owned by someone else so I guess I should have took a look before saying to look there ...Show All

• Huy Nguyen WWF Performance

  I created a simple console app to host the workflow engine and run a simple sequential workflow consisting of a while condition, a sequence, a couple of trivial custom activities, and an incrementor to kill the while loop after 10 iterations. On a fairly powerful developer machine, running a release build, running outside the debugger, performance measurements showed that it took about 1.0 second to load and unload the workfl ...Show All

• Marty_M TransactionScope FaultHandler problem

  I have a sequential workflow with a TransactionScopeActivity within which I throw a System.Exception under certain circumstances. I also have a corresponding FaultHandlerActivity to handle the System.Exception. This works fine when I host the WorkflowRuntime in a Windows EXE. However when I host the WorkflowRuntime in a WindowsService the FaultHandler does not get activated, instead the trace just shows that an exception has been thrown and ...Show All

• Udo Eberhardt ASP.NET hosting (WebService) of Windows Workflow Foundation

  Hi all, I've decided to go about hosting the runtime in an ASP.NET environment, specifically a webservice. All is looking good on the 'design table' except for ONE thing...... Upon hosting the WorkflowRuntime, and I fire up a sequential workflow, how do I know when it's finished (I'd like to be able to use the Async features in ASP.NET 2.0) The reason why I ask is most of the examples either wait on the current thread - waitHandle.j ...Show All

• yashpal singh Designers built to access fields only?

  Designers for activities like InvokeMemberActivity and EventSinkActivity show only fields (member variables) in the drop-down list of available choices for parameters. These lists do not include public properties. Why It's always been our practice to make member variables private and control access to them through public properties. I can manually type in the property name, but the designer tries to add a field to the XOML file (which clashes w ...Show All

• klusner taskbar tooltips - please fix!

  In Windows XP, if you put the taskbar at the top of your screen, as I do, the taskbar button tooltips appear on the taskbar and obscure the buttons - very annoying! Of course, if the taskbar is at the bottom of the screen you don't have this problem, the tooltips appear above the bar, no matter where the exact position of the pointer is. The fix is to always display the tooltip below the taskbar if the bar is at the top of the screen. I like ...Show All
