If you want to upload a big file to server or do a long time action in Flex/ActionScript like HTTPService to communicate with an external server that hosts the database, a time delay function like Sleep() will be needed.
So, is there a sleep function in flex 2 ? Run multi-thread, one sleep and wait the result of this thread and the other will be continue.
Unfortunatly, because the flash player, from our perspective, is single threaded so we can not do that.
