Resume the bookmark after a value to change

Please I really need help, I just post this https://stackoverflow.com/questions/7217897/questions-about-activities-scenario-in-wf but nobody answered.

My question, How can I wait the approve value to become true which I read it via method in WCF, then resume the workflow ?

I'm using rehosted workflow for the user!

Than开发者_JAVA技巧k you.

If you're trying to poll a WCF method and do something when true is returned you could use a DoWhile activity with a Delay activity and your call to the WCF method inside of it. Set the Delay activity duration to the amount of time between each polling attempt and do something to exit the DoWhile loop when a value of true is returned.
