How to start Indy TCP Server with parameters?

Question

I am building a TCP Server using Indy 10 (from Delphi 2009). In OnExecute event I need to acces some data from the main thread. It is possible to pass that data to the server thread when I start it ? The server is started with IdTCPServer1.Active:=True; so I don't see how I can pass some parameters.

Answer 1

It is not possible to pass extra parameters to TIdTCPServer . Your server event handlers will have to retrieve the data from the main thread when needed.

To keep track of per-connection data across events, you can use the TIdContext.Data property, or derive a custom class from TIdServerContext and assign it to the TIdTCPServer.ContextClass property. For instance, your OnConnect event handler can retrieve the latest data from the main thread using TIdSync or TThread.Synchronize() , and then cache it in the context for OnExecute to use.
