talking to foo_controlserver

I'm trying to write an app using the compact .NET framework to remote control foobar2000 using the foo_controlserver plugin.

It works fine as far as controlling the current song and parsing the results...

However, that only works if I read one line at a time from the output. Whenever I try to read multiple lines (for example, getting the playlist or searching the playlist) I am having trouble with the communications to the server.

doing streamreader.readline() works fine for one line instances....since I know exactly how many lines I"m getting...well basically when to end the read

however, since foo_controlserver doesn't close the connection, and getting search results and the playlist means I have an unknowable amount of lines coming to me I don't know how to gracefully be done reading....

I've tried doing something like

Code: [Select]

while(sr.Peek() > 0)
{
   sr.Read(someCharArray,0,someCharArray.Length);
   outputStringBuilder.Append(someCharArray);
}

sr.DiscardBufferedData();

but I end up getting duplicate data...I'm always off by one read. I don't think that DiscardBufferedData() is doing anything on the NetworkStream ...

any ideas? here's the current code I'm using...which works fine for single lines

Code: [Select]

  public static bool InitializeConnection()
  {
      bool inited = false;
      try
      {
    IPEndPoint localEP = new IPEndPoint(Dns.Resolve(Dns.GetHostName()).AddressList[0],0);
    IPEndPoint remoteEP = new IPEndPoint(IPAddress.Parse(ipAddress),3333);
    client = new TcpClient(localEP);
    //client.LingerState =
    client.Connect(remoteEP);
    inited = true;
      }
      catch
      {
    
      }
      return inited;
      
  }  

  public static string SendCmd(string cmd)
  {
      cmd = cmd + "\n";
      StreamWriter sw = new StreamWriter(client.GetStream());
      StreamReader sr = new StreamReader(client.GetStream());
      sr.DiscardBufferedData();
      sw.Write(cmd);
      sw.Flush();
      string output = sr.ReadLine();
      return output;
  }

Sorry, I realized after the fact that this was in the wrong forum.

Anyhow, I've got it figured out....had to use sockets to do what I wanted (well, may have been possible with TcpClient, but I don't konw).

Anyhow, here's the code if anyone wants to re-use it

Code: [Select]

  public string SendCmd(string cmd)
  {
      cmd = cmd + "\n";
      StringBuilder outputBuilder = new StringBuilder("");
      byte[] inputData = Encoding.ASCII.GetBytes(cmd);
      s.Send(inputData);
      s.Poll(250000,SelectMode.SelectRead);
      while(s.Available > 0)
      {
    byte[] outputData = new byte[s.Available];
    int received = s.Receive(outputData,0,outputData.Length,SocketFlags.None);
        outputBuilder.Append(Encoding.ASCII.GetString(outputData,0,received));
    s.Poll(100000,SelectMode.SelectRead);
      }
      return outputBuilder.ToString();
  }


  public bool InitializeConnection()
  {
      bool inited = false;
      
      try
      {
    if(s != null)
    {
        s.Close();
    }
    s = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
    IPEndPoint remoteEP = new IPEndPoint(IPAddress.Parse(textBox2.Text),3333);
    s.Connect(remoteEP);      
    byte[] outputData = new byte[s.Available];
    s.Receive(outputData);
    inited = true;
      }
      catch(Exception ex)
      {
    MessageBox.Show(ex.ToString());
      }
      return inited;
      
  }

If anyone's interested in the app, just let me know and I'll post it here.

It has the following functions:

-> Play, Pause, Stop, Random, Previous, Next

-> Change playback mode

-> Load playlist, view by artist (slow for big playlists..on my ipaq anyways)

-> Search playlist (much faster, reccommended for large playlists)

It requires foo_controlserver which is really what does all the work. Very cool plugin.

I tried writting the exact same application...
Learning C# and writting this thing i wanted soooo bad.. at the same time. I stopped right after i made Play/Pause, Next, Previous, Stop buttons and a console for input and output. I was planning on making a systray control thing and playlist search etc... but i don't have too much free time

I want this baaaad cuz i use Winamp at work, with a remote TCP plugin thingie because i'm the only one with speakers and a large drive to host the music, but 3 people in the office that want to be able to control the player... And i want to switch to foobar (wich i use at home since the early beta stages)...

Anyhow... i'd love to try your little app if i may?

If you wanted to convert it to a winforms app (non-compact framework) then I believe pretty much all the code you should be able to c/p into a winforms project and make it compile. if anything only minor tweaks would be needed but I doubt even that.

I mean, the GUI could use redesigning if it's going to be full fledged windows app...but I believe since the compact framework is a pure subset of the main winforms classes that it should work fine.
