• KnowsEnuf2BDangrous How to get workflow instance from database?

  Perhaps it is very easy, but i really wondering to find this solution. Please tell me details! Thanks! Could it be that you just start the workflow and shoot the event immediately to it Because if you do so and do not send the event like this that it is delivered, when the workflow begins to idle, you get this message. The reason is simple: If the workflow waits for a message it creates a queue for that where it expects the mess ...Show All

• Murthyan Sequential Workflow Cancellation

  This question has appeared before but never with a clear answer. When would a SequentialWorkflowActivity execute its cancellation handler The SDK sample "CancelWorkflow" does indeed "cancel" the workflow by raising an exception, but this isn't a "cancel" in the sense that the cancellation handler runs.

• stevenback7 Pointers on Fancifying the WorkflowView

  I've gone through the sample rehosting lab, and I get how the basics work to rehost the designer; however, I'm not clear (and can't seem to find much) on actually modifying the default L&F. I think I can use a WorkflowTheme to modify the colors and such, but what about changing what's actually displayed in the designer for an activity I'll keep digging, but I thought I'd ask here in case someone can point me in the right direction. I' ...Show All
