• IdahoErick 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

• gv How does it compare to the ISV's like K2 & Captaris Teamplate??

  This weekend I'm planning to take a dive into WWF, very excited about the potential of this new platform. One of the first things I want to find out is how WWF compares to other workflow solutions. I've worked with both K2.net and Captaris Teamplate, from which I definitely prefer the first one. Of course the integration in MS products will be far better, but how does it perform, how do the BAM tools compare, does it bring easier user managemen ...Show All

• Kevin Mulvihill How to prevent an Workflowinstance from terminating

  Hi there I'm currently working on a (runtime-)service that should start a workflow for errorhandling if an instance faults. The service works fine as long as I trigger it by the instance's terminate event (Runtime -> WorkflowTerminated), but I want to prevent  the instance from terminating and instead suspend it so it could be resumed and starts at the State that caused an error previously. Is anyone there who could give me a ...Show All

• Albert C Getting Vista File Open dialog with .NET application

  Our application is written in C# 2.0 and using standard file open/save dialogs. In XP, these are pretty basic dialogs, but on Vista they remain the xp-style dialogs and not the Vista-specific open dialog. I've noticed with MFC based applications, if you use the common dialog you can get the Vista specific open dialog when running the same app on Vista. Any idea how we can get the OS-specific open dialog in C# ... if not possible withou ...Show All

• Math23 Using InvokeWorkFlow Activity

  Hello - We have a program hosted by the Console that consists of two workflows. The first waits in a while loop for text files to appear in a folder; when one does, this workflow uses InvokeWorkFlow to kick off the second workflow which will write the file name into another file. The problem is that when the second workflow is finished, the first workflow gets terminated. Why is that I've understood from the documentation that this should not h ...Show All
