Injecting a DLL via EasyHook

[Viano]

Hi everyone,

I am trying to learn about how to use EasyHook but I am not even able to run the example provided. I seem to have all files in my "Debug" (FileMonInject.dll) directory but I'm still getting exceptions about missing files.

The following is my code.

namespace Hooking
{

    public class FileMonInterface : MarshalByRefObject
    {
        public void IsInstalled(Int32 InClientPID)
        {
            Console.WriteLine("FileMon has been installed in target {0}.\r\n", InClientPID);
        }

        public void OnCreateFile(Int32 InClientPID, String[] InFileNames)
        {
            for (int i = 0; i < InFileNames.Length; i++)
            {
                Console.WriteLine(InFileNames[i]);
            }
        }

        public void ReportException(Exception InInfo)
        {
            Console.WriteLine("The target process has reported" +
                              " an error:\r\n" + InInfo.ToString());
        }

        public void Ping()
        {
        }
    }

    class Hooking
    {
        static String ChannelName = null;


        public Hooking() 
        {
            hook();
        }

        static public void hook() {
            try
            {
                Config.Register(
                "A FileMon like demo application.",
                "FileMon.exe",
                "FileMonInject.dll");

                Console.WriteLine("Registered!");

                RemoteHooking.IpcCreateServer<FileMonInterface>(ref
ChannelName, WellKnownObjectMode.SingleCall);

                RemoteHooking.Inject(2776, "FileMonInject.dll", "FileMonInject.dll", ChannelName);

                Console.ReadLine();
            }
            catch (Exception ExtInfo)
            { 
                Console.WriteLine("There was an error while connecting to target:\r\n{0}", ExtInfo.ToString());
            }
        }
    }
}

So RemoteHooking.Inject(...) is failing with the following Exception.

There was an error while connecting to target:
System.IO.FileNotFoundException: File or Assembly "FileMonInject, Version=1.0.0.0, Culture=neutral, PublicKeyToken=d34a061f079be347" or its dependency cannot be found. The system cannot find the file.

I hope in this section I will not get flamed to death

Update:

No idea why, but now I am getting something completely else.

There was an error while connecting to target:
System.Reflection.TargetInvocationException: Target has thrown exception. ---> System.Runtime.Remoting.RemotingException: Tried to call method of type "FileMon.FileMonInterface" declared in "Hooking.FileMonInterface".

Update 2:

System.Runtime.Remoting.RemotingException: Failed to connect to an IPC Port: Access is denied.

Any clue on this one?

EDIT:
Just ignore this, I managed to inject a DLL via EasyHook into WoW
