Ya okay i see that ComctSerializedObjects should work but i dont quite get it..
Can you give an example on how to open a Connection to a specific port and ip and send a Struct to it ?

This is the sample code from the codeproject link to send data from client

The send method of NetworkUdpClient takes System::Object. So you can pass any type of structure/class derived from System::Object.

<H3>Client side using UDP</H3><PRE lang=mc++>try {

    // opens listener
    Network::NetworkUdpClient* udpClient =
             new Network::NetworkUdpClient(S"localhost", 4567);

    // sends and receives object through the two sides
    udpClient->send(S"Hello World!");
    Object* object = udpClient->receive();


} catch(Exception* e) {
    Console::WriteLine(S"Error sending receiving messages");
