• avanderlaan Can revert back in to XP?

  after instaling vista on the same drive as xp can i revert back to xp i am not in the mood for reinstaling my xp all over again. This question has nothing to do with Vista development and you should find an appropriate forum to ask it. However, you should NEVER put two OSes on the same partition. If they are in different partitions, Vista will set up as dual boot, and you can choose every time which OS t ...Show All

• Souri Confused on why is is possible to drop activities in .XOML and .XOML.CS files?

  Hi everybody, I may be overlooking something obvious, but this is sort of confusing to me, so I would appreciate a clarifying voice on this. If I create a WF console app, delete the original "Workflow1.cs" file, and add a "Sequential workflow (with code separation)" item, then I get 2 files in the solution explorer: "workflow1.xoml" and "workflow1.xoml.cs". I can click on each one of those two files, and add activities separately ( ): ...Show All

• AlanH-SA Dynamically setting the next state from within a Workflow...

  I'm trying to set the next state from within a sequential workflow handling an event. The SetState activity only allows the state to be set at design time. External to the Workflow, using the StateMachineInstance, you can do a SetState by doing a: SetStateEventArgs eventArgs = new SetStateEventArgs(stateId); workflowInstance.EnqueueItem(System.Workflow.Activities.StateMachineWorkflow.SetStateQueueName, eventArgs, null, null); For a State Bas ...Show All

• M D Larsen Workflow arrows not showing up - what's wrong ?

  Hi, I just installed WWF Beta on my machine (W2k3 SP1, VS2k5 B2) and tried the "State machine" lab. I could make all the steps that were shown and the project compiles fine (haven't come to the step where I could run the project, though). But when I look at the workflow overview, I cannot see the arrows that mark state changes! The layout is still "all shapes in onw column", so it seems the designer has not caught my "change state" shapes inside ...Show All

• Laser Lu 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.

Is the documentation available on-line or as a separate download as I don't have VS2005 installed I ag ...Show All

    Sir Mr Tilleson,     I am a Software Eng. student and I'm doing a technical report about Vista 's new interface.

They all combine the other aspects as security, reliability and many other features. So Mr Tilleson if u can recommend any websites that discuss this issue, it would be very helpful.
