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.
