WPF C # - Mettre à jour la barre de progression d'un autre thread

Je suis coincé à essayer de mettre à jour une barre de progression à partir d'autres threads couru dans une classe différente. Pour expliquer ce que je fais, je pense, une image sera meilleure. Je veux mettre à jour la barre de progression dans l' //ICI point :

J'ai essayé à l'aide d'un délégué, essayé avec ReportProgress et je pense que je l'ai fait essayé à utiliser tout ce que google a signalé dans les 100 premiers résultats, sans succès. Je suis encore à apprendre WPF et peut-être idiot comme façon de procéder, je suis à la recherche d'une façon rapide et sale pour faire le travail, mais n'hésitez pas à me dire ce que je doit refonte pour un nettoyeur application.

MODIFIER : Plus de code.

Dans ExecutorWindow.xaml.cs :

public void RunExecutor()
{
    //CREATE BACKGROUNDWORKER FOR EXECUTOR
    execBackground.DoWork += new DoWorkEventHandler(execBackground_DoWork);
    execBackground.RunWorkerCompleted += new RunWorkerCompletedEventHandler(execBackground_RunWorkerCompleted);
    execBackground.ProgressChanged += new ProgressChangedEventHandler(execBackground_ProgressChanged);
    execBackground.WorkerReportsProgress = true;
    execBackground.WorkerSupportsCancellation = true;
    //RUN BACKGROUNDWORKER
    execBackground.RunWorkerAsync();
}
private void execBackground_DoWork(object sender, DoWorkEventArgs e)
{
    myExecutor = new Executor(arg1, arg2);
    myExecutor.Run();            
}

private void execBackground_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    MessageBox.Show("RunWorkerCompleted execBackground");
}

private void execBackground_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    ExecutorProgressBar.Value += 1;
}

//TESTING 
private void updateProgressBar(int i)
{
    ExecutorProgressBar.Value += i;
}

public delegate void callback_updateProgressBar(int i);

Dans Exécuteur Testamentaire.cs :

public void Run()
{
    string[] options = new string[2];
    int i = 0;

    while (LeftToRun > 0)
    {
        if (CurrentRunningThreads < MaxThreadsRunning)
        {
            BackgroundWorker myThread = new BackgroundWorker();
            myThread.DoWork += new DoWorkEventHandler(backgroundWorkerRemoteProcess_DoWork);
            myThread.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorkerRemoteProcess_RunWorkerCompleted);
            myThread.ProgressChanged += new ProgressChangedEventHandler(backgroundWorkerRemoteProcess_ProgressChanged);
            myThread.WorkerReportsProgress = true;
            myThread.WorkerSupportsCancellation = true;

            myThread.RunWorkerAsync(new string[2] {opt1, opt2});

            //HERE ?
            CurrentRunningThreads++;
            i++;
            LeftToRun--;

        }
    }

    while (CurrentRunningThreads > 0) { }
    logfile.Close();
    MessageBox.Show("All Tasks finished");
}

private void backgroundWorkerRemoteProcess_DoWork(object sender, DoWorkEventArgs e)
{
    BackgroundWorker myBackgroundWorker = sender as BackgroundWorker;
    string[] options = (string[])e.Argument;
    string machine = options[0];
    string script = options[1];
    //UPDATE HERE PROGRESSBAR ?
    RemoteProcess myRemoteProcess = new RemoteProcess(machine, script);
    string output = myRemoteProcess.TrueExec();
    //UPDATE HERE PROGRESSBAR ?
    this.logfile.WriteLine(output);
}

private void backgroundWorkerRemoteProcess_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    CurrentRunningThreads--;
}

private void backgroundWorkerRemoteProcess_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    //myExecWindow.ExecutorProgressBar.Value = e.ProgressPercentage; //TESTING
    //ExecutorWindow.callback_updateProgressBar(1); //TESTING 
}

EDIT 2 : je l'ai eu! Simple en fait, mais je suppose que j'ai été à la recherche de trop près pour le savoir.

Dans mon ExecutorWindow classe :

private void execBackground_DoWork(object sender, DoWorkEventArgs e)
{
    myExecutor = new Executor(arg1, arg2);
    myExecutor.Run(sender);
}

private void execBackground_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    ExecutorProgressBar.Value += 1;
}

Et dans mon Exécuteur de la classe :

private BackgroundWorker myExecutorWindow;

[...]

public void Run(object sender)
{
            myExecutorWindow = sender as BackgroundWorker;
            string[] options = new string[2];
            int i = 0;

            while (LeftToRun > 0)
            {
                if (CurrentRunningThreads < MaxThreadsRunning)
                {
                    BackgroundWorker myThread = new BackgroundWorker();
                    myThread.DoWork += new DoWorkEventHandler(backgroundWorkerRemoteProcess_DoWork);
                    myThread.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorkerRemoteProcess_RunWorkerCompleted);
                    myThread.ProgressChanged += new ProgressChangedEventHandler(backgroundWorkerRemoteProcess_ProgressChanged);
                    myThread.WorkerReportsProgress = true;
                    myThread.WorkerSupportsCancellation = true;

                    myThread.RunWorkerAsync(new string[2] {opt1, opt2});

                    CurrentRunningThreads++;
                    i++;
                    LeftToRun--;      
                }
            }

[...]

private void backgroundWorkerRemoteProcess_DoWork(object sender, DoWorkEventArgs e)
        {
            BackgroundWorker myBackgroundWorker = sender as BackgroundWorker;
            myBackgroundWorker.ReportProgress(1);
            //PROCESSING MY STUFF HERE
            myBackgroundWorker.ReportProgress(1);
        }

        private void backgroundWorkerRemoteProcess_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            myExecutorWindow.ReportProgress(1);
        }

Merci !
