(solved) Going back to cander's IPlugin tutorial

(Ref: http://www.vbforums.com/showthread.p...=plugin+cander)

Hi. I've implemented something very similar to Cander's IPlugin tutorial. In fact, I'm using almost the exact same code for the LoadPlugin() function. However, after I create the plugin object, I am unable to cast it to the interface. I recieve a "the specified cast is not valid" error. Here's my interface:

using System;
using BattleNet;
using BattleNet.Bots;

namespace IBPlugin
{
    public interface IHost
    {
        string Author();
        string Version();
        ChatBot Bot();

    }

    public interface IPlugin
    {
        string Author();
        string Name();
        string Version();
        string Info();
        bool Initialize(IHost host);
        bool Shutdown();

        event ChatBot.BnEvent_Channel OnChannel;
        event ChatBot.BnEvent_Emote OnEmote;
        event ChatBot.BnEvent_Error OnError;
        event ChatBot.BnEvent_Flags OnFlags;
        event ChatBot.BnEvent_Info OnInfo;
        event ChatBot.BnEvent_Join OnJoin;
        event ChatBot.BnEvent_Leave OnLeave;
        event ChatBot.BnEvent_Name OnName;
        event ChatBot.BnEvent_Null OnNull;
        event ChatBot.BnEvent_Other OnOther;
        event ChatBot.BnEvent_Talk OnTalk;
        event ChatBot.BnEvent_User OnUser;
        event ChatBot.BnEvent_WhisperIn OnWhisperIn;
        event ChatBot.BnEvent_WhisperOut OnWhisperOut;
        event ChatBot.LbEvent_Connected BotConnected;
        event ChatBot.LbEvent_Disconnected BotDisconnected;
        event ChatBot.LbEvent_Error BotError;
        

    }

} 

And here's the line from the other project where it cops out..

if(pluginImplemented.GetInterface("IPlugin") != null)
{
    // Invalid cast!
    plugin = (IPlugin)Activator.CreateInstance (pluginImplemented);
                            
    if (plugin.Initialize(this.Host))
    {
        Console.WriteLine(plugin.Name() + " " 
        + plugin.Version() + 
        " by " + plugin.Author() + " Loaded.");

        Plugins.Add(plugin);
    }
    else
    {
        Console.WriteLine("Plugin failed to initialize.");
    } 

And here's the implementation...

using System;
using IBPlugin;
using BattleNet.Bots;

namespace IronBot
{
    public class Plugin : IPlugin
    {
        private IHost _host;

        public string Author()
        {
            return "Kaegan";
        }
        public string Version()
        {
            return "1.0";
        }

        public string Name()
        {
            return "Test Plugin";
        }

        public bool Initialize(IHost host)
        {
            _host = host;
            return true;
        }

        public bool Shutdown()
        {
            return true;
        }

        public string Info()
        {
            return "Just a simple plugin.";
        }

        public event ChatBot.BnEvent_Channel OnChannel = null;
        public event ChatBot.BnEvent_Emote OnEmote = null;
        public event ChatBot.BnEvent_Error OnError = null;
        public event ChatBot.BnEvent_Flags OnFlags = null;
        public event ChatBot.BnEvent_Info OnInfo = null;
        public event ChatBot.BnEvent_Join OnJoin = null;
        public event ChatBot.BnEvent_Leave OnLeave = null;
        public event ChatBot.BnEvent_Name OnName = null;
        public event ChatBot.BnEvent_Null OnNull = null;
        public event ChatBot.BnEvent_Other OnOther = null;
        public event ChatBot.BnEvent_Talk OnTalk = null;
        public event ChatBot.BnEvent_User OnUser = null;
        public event ChatBot.BnEvent_WhisperIn OnWhisperIn = null;
        public event ChatBot.BnEvent_WhisperOut OnWhisperOut = null;
        public event ChatBot.LbEvent_Connected BotConnected = null;
        public event ChatBot.LbEvent_Disconnected BotDisconnected = null;
        public event ChatBot.LbEvent_Error BotError = null;
    }
} 

The ChatBot class is implemented in within the BattleNet.Bots namespace I created. I made sure that the versions of the interface library and Battlenet library being referenced by each project was the same. Any suggestions? Perhaps its a problem with the events? I've never created an interface with events before...

[PT Exorcist]

are both projects(plugin and host) implementing the same DLL? u cant hard code each plugin in the host and plugin, it must be exactly the same dll!

[sunburnt]

Yup, they both reference the same library.
EDIT: Ha, I misunderstood what you meant! I had the plugin dlls in a different directory with duplicate copies of the battlenet and iplugin libraries. when I put them in the same folder, it worked perfectly. Thanks!
