  • Hi Kevin,

    Please try the following. I tested the following. Its working perfectly both in foreground and background mode. Arralist is not required actually. but It was working when I added arraylist. So you try with out arraylist, if not use the code as it is.

    private void button1_Click(object sender, EventArgs e)

    {

    this.Hide();

    }

    private ArrayList stateList = new ArrayList();

    ActiveSyncStatus syncStatus;

    private void Form1_Load(object sender, EventArgs e)

    {

    SystemState s = new SystemState(SystemProperty.ActiveSyncStatus);

    s.Changed += new ChangeEventHandler(ActiveSyncchanged);

    stateList.Add(s);

    }

    private void ActiveSyncchanged(object sender, ChangeEventArgs args)

    {

    syncStatus = (ActiveSyncStatus)args.NewValue;

    if (syncStatus.Equals(ActiveSyncStatus.Synchronizing))

    {

    MessageBox.Show("Synching");

    }

    }

    Please let me know if my code is not solving your problem.
