New Message on dotNET User Group Hyd VJs Tip Of The Day Reply   Reply to Sender   Recommend Message 47 in Discussion From: VishalRJoshi Asynchronous Programming in Web Services Callback functions are the way to implement Asynchronous programming in Web services... We will get into details of this topic sometime but now just an overview... A client calls the Begin method on the server object and passes a reference to the callback method... The asynchronous method on the server object finishes execution and gives a call back to the method on the client object... This method in client object now causes the call to End method on the server object.... The End Method then returns the result to the client... Well why would you do such a thing??... The simple reason can be when your server side execution is really going to take long and you do not want to wait for all that processing to happen... PS: I just remembered a saying from a wise man, thought I would remind you all of that too... "If Everything is under control... Then you are not moving fast enough..." :-) Vishal Joshi Microsoft MVP .Net If You Think YOU CAN...
