Regarding Socket

[daffodils180]

Hi all,

Here are some questions, plz kindly share your ideas on that

1) Where should the socket be closed ideally? is it while closing the application or after receiving the response from the device.
2) How to know if any data has arrived on the socket? is there any in-built function triggered on receiving some data on the socket?
3) How do v know if the socket is already created?

Thanks & Regards

Neither. Close it when you're finished with it.

2) How to know if any data has arrived on the socket? is there any in-built function triggered on receiving some data on the socket?

Use the asynchronous socket methods. When your callback is invoked, data is available on the socket or the socket has been closed.

3) How do v know if the socket is already created?

Sockets can only be created once so if you get an exception creating the socket, it's already created.
