• pcprof HELP! shell extensions on Vista

I've since wiped the comp and I just downloaded the new Dec CTP to give it a whirl.... Well, no joy. The install process ran, rebooted the PC and then stopped. I left it for about THREE hours so I am pretty sure it was ...Show All

• Nestor Pira Ifelse activity in workflow

  How can I set the condition for the ifelse activity . how do I invoke the branching based on the condition. Actually, this isn't exactly what the Parallel activity is for.  The Parallel activity is used when you want two sequences to run at the same time ( It literally will spawn the contained activities on another thread ).  The solution you describe may work but it's a rather long way to go for a simple switch construct.
