Adding a reference to MediaMonkey

Here you can find resources related to automating MediaMonkey in .NET (C#/VB.NET), including very simple beginners tips & tricks.

Adding a reference to MediaMonkey

1. Choose Add Reference
2. Go to the COM Tab
3. Choose "MediaMonkey Library"

The base Namespace for MediaMonkey is SongsDB:

  using SongsDB;

Subscribing to events

Subscribing to events does not work with external applications, like .NET applications if they make the connection to the MediaMonkey application. See:

• Events don't work with C#
• Trouble With Handling COM Events

A solution is presented in:

• MonkeyToys: VB.NET extension adding MCE remote support

Walkthrough

This solution is based on making your assembly ComVisible, registering it and letting an auto-script in MediaMonkey create your application object. This can be accomplished by creating a class along the lines under.

• First build and run your program, then call the RegisterCOM() Method to register your application with COM.

(continued after C#-code)

using System.Reflection;
using System.Runtime.InteropServices;
using SongsDB;

namespace SomeNamespace {
  [ComVisible(true)] // this overrides [assembly: ComVisible(false)] (is set by project options dialog) so registry don't get bloated with unneeded types
  public class EventTest {
    public SDBApplication SDB { get; private set; }

    public static void RegisterCOM() {
      RegistrationServices rs = new RegistrationServices();
      rs.RegisterAssembly(Assembly.GetExecutingAssembly(),
        AssemblyRegistrationFlags.SetCodeBase);
    }
    public static void UnRegisterCOM() {
      RegistrationServices rs = new RegistrationServices();
      rs.UnregisterAssembly(Assembly.GetExecutingAssembly());
    }
    public void Init(SDBApplication mm) {
      this.SDB = mm;
      this.SDB.set_Objects(Assembly.GetExecutingAssembly().GetName().Name, this);
      this.SDB.OnPlay += () => { System.Windows.MessageBox.Show("OnPlay event fired!"); };
    }
  }
}

• Add an autoscript-to mediamonkey (ie. a file in ...\MediaMonkey\Scripts\Auto) named SomeScript.vbs that starts your application and runs the Init function. It's contents should be like this:

Sub OnStartup
   Set o = CreateObject("SomeNamespace.EventTest")
   o.Init(SDB)
End Sub

• When you now start MediaMonkey it will connect to your application and event firing will work.
