I would like my application to be able to make TCP/IP connection. If I would have only one thread or if I knew at the design time how many connections I have to make, then using TClientSocket would be as simple as putting desired number of them on the form or data module. But: 1. I dont know the thread number at the design time 2. each thread needs to make one TCPIP connection 3. the threads do not have message queue handling What are my options then? 1. can I dynamically create TClientSocket objects at the runtime and make them owned by one of the forms or data modules? If so, how do I do that (I mean Owner handling - should I put the owner as the constructor parameter or should I use InsertComponnent method of the form?) 2. or maybe i should use simple API calls - but I'm used to use TWinSocketStream I don't like this soultion - I know how to do it but I would like to use VCL componnents How TClientSocket componnent fixes it's Handle property, which points to the form receiving messages? Is it obtained after assigning Owner? -- ([-: May The Force Be With You! :-]) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Shon Back to top Remy Lebeau (TeamB) Guest Posted: Thu Jan 29, 2004 7:27 pm    Post subject: Re: TClientSocket "Shon" <Sebastian.Choromanski@%N%O%inteligo%S%P%A%M%.pl> wrote Quote: What are my options then? Create a new thread class that has a TClientSocket as a member that is instantiated in the constructor and freed in the destructor. Then simply set the ClientType property to ctNonBlocking and use a TWinSocketStream inside the thread'sExecute() method to access the socket. Then you simply spawn a new thread instance when needed and it will handle its particular socket connection separately from other connections/threads.

Maybe you ment ctBlocking? Nevertheless thank you for the answer - the idea of the class member seams to be perfect for me! I will give it a try!

I understand.
