❔ implementing licensing system in my app
Hi guys, I would like to implement some kind of license system to my app written in c#. I've been considering APIs like keyauth.cc...but can you maybe recommend something better? What do you use in your apps? Thanks for the answer in advance

read TCP stream issue
Hi, Maybe you will be able to give me some tips 😅 I am writting a tool using already created API. The creator of the api doesn't know c# so he isn't able to help me with that issue (API is written in C++ but it should work fine with c# too). In short - tool sends json messages using TCP socket. Messages are terminated with '\1' character or 0x01 byte (so one "packet" can in fact be stored in 2 <or more> messages received from a bot). and this is the part I have no idea how to handle. I wrote something like that: 
//function to receive messages from tcpserver
while (true)
{
    byte[] numArray = new byte[TCPClient.ReceiveBufferSize + 1];
    TCPClientStream.Read(numArray, 0, TCPClient.ReceiveBufferSize);
    string[] msg = Strings.Split(Encoding.UTF7.GetString(numArray), "\u0001");
    ...
    later json deserialize etc
}
//function to receive messages from tcpserver
while (true)
{
    byte[] numArray = new byte[TCPClient.ReceiveBufferSize + 1];
    TCPClientStream.Read(numArray, 0, TCPClient.ReceiveBufferSize);
    string[] msg = Strings.Split(Encoding.UTF7.GetString(numArray), "\u0001");
    ...
    later json deserialize etc
}
but it's not reading packets which are stored in more than one tcp message. do you have any ideas how can I fix that? I made a tool with QT and c++..and ok. it works fine. but I personally hate c++ and "upgrading" this tool is a horror for me. With C# it seems to be not reading part of the messages, which should be handled. I checked that and seems to be missing about 30% of the packets. There is no official c# api...but this kind of api should be possible to work with any language which supports JSON and TCP sockets. thanks for any tip in advance and have a nice day!
