Using Named Pipes

Both the C# form application, and the C++ injected DLL will share a named pipe to communicate back and forth. This will let us trigger internal functions within the game whenever we want via our C# application functions.

First, make your C++ DLL with a named pipe called EQTpipe.

Then, we use our C# code to send the "warp" command through the named pipe to trigger our game's internal function. This example uses the button named "teleportBtn" with the click action "teleportBtn_Click". Don't forget to inject your DLL prior to calling any named pipe functions.

C# Code

public void NewThreadStartClient(string func)
    {
        using (NamedPipeClientStream pipeStream = new NamedPipeClientStream("EQTPipe"))
        {
            if (!pipeStream.IsConnected)
                pipeStream.Connect();

            //Debug.Write("[Client] Pipe connection established");
            using (StreamWriter sw = new StreamWriter(pipeStream))
            {
                if (sw.AutoFlush == false)
                    sw.AutoFlush = true;
                sw.WriteLine(func);
            }
        }
    }

private void injectDLLBtn_Click(object sender, EventArgs e) {
    MemLib.InjectDLL("my.dll");
}

private void teleportBtn_Click(object sender, EventArgs e) {
    Thread ClientThread = new Thread(() => NewThreadStartClient("warp"));
    ClientThread.Start();
}
