So, does this, "...this > may cause a lot of trouble", apply? Yes, since you are creating new threads. If you create the components in the thread constructor (or drop it on the form), their event handler will run in the main thread context which is the active thread when the constructor is called. You /MUST/ create the component from the Execute method (or any method called from the Execute), and destroy it from the Execute method. You cannot have on ICS component (let's talk about FTP as an example) dropped on a form and the create a few threads, each one using the same component to do file transfer. That will /not/ work. You need a separate component for each concurrent file transfert no matter if you use threads or not. > I should expect trouble if I have > multiple ICS components all executing on the main thread? ICS is asynchronous, so you /DONT NEED/ multithreading to do several things simultaneously ! You /MAY/ use threads to benefit from multi-processor/core systems or to do lengthy processing. But this is defenitely required for ICS. If you want to query 4 webpages at the same time, just use 4 HTTP client components and call GetAsync on each one. They will all 4 do their job in parallel without blocking each other and without using threads. -- francois.pie...@overbyte.be Author of ICS (Internet Component Suite, freeware) Author of MidWare (Multi-tier framework, freeware) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
