Re: Checking TCP/IP connection when using GUIs

Hi

I am currently programming a GUI to communicate with a remote host via
TCP/IP. I use the fopen, fprintf and fscan functions to do so on a TCP/IP
object I have created. This works fine so far.
Now the part I am not sure how to accomplish.
My server/remote host is able to send out a signal when my client (GUI) is
connected, to tell that the connection is alive e.g. "Your are connected",
therefore I want to check for this message every e.g. 1 sec. to check if
my connection is up and running, but to do so, according to my knowledge,
I have to place my scan in a loop that checks every second.
So my questions are
1) Where do I have to place this loop in my GUI-code to make it check
every second that the connection is ok without me pushing any buttons?
2) and will this lock my entire GUI so that I cannot execute any other
callbacks or can I somehow still execute my callbacks?

Use a timer object.
