TCP Listener in CTRL

[marcel@realsolutions.nu]

Hello,

Is there anybody that has found a way for TCP listening in the CTRL language? (maybe a CTRL extension)

I need to open a TCP port for listening, and report the data as soon as a device is connecting to this port and sends data. (I also need to know his IP and port nr.)

Hope somebody can help me with this!


Kind regards,

I've created a quick solution for this in a ctrl extension.
See attached example. You use it like this:

#uses "CtrlTcpServer"

main()
{
DebugN(tcpServer(5555, "callback"));
}

callback(string data, string host)
{
DebugN("incoming call from ", host, data);
} https://www.winccoa.com/fileadmin/image ... Server.zip

Thanx Martin,

Sounds good!
I'm going to test try it and let you know

Hello

We compiled the example code for 3.10.2 32Bit and it works fine.

After that we tried to compile the example code for 3.11 64Bit and we got following error:

Oh great ... not good. The problem is that the mentioned header file uses some Qt classes but we are not allowed to deliver Qt header files.
Our public API should really not need Qt header includes.
This must be fixed on our side.
In the meantime as a workaround you can download Qt sources (or at least the mentioned header files) from the Qt project (Qt version 4.8.4):
http://download.qt.io/archive/qt/4.8/4.8.4/
and make sure the compiler finds QQueue etc.
