private void btnAutoSend_Clic         


        

Answer 1

You can't pass extra parameters to an event handler like that.

Store your value in an object level variable so that it can be accessed in the event handler.

private string receiver;

public System.Timers.Timer timer = new System.Timers.Timer(200);
private void btnAutoSend_Click(object sender, EventArgs e)
{
    timer.Enabled = true;
    receiver = 'your val';
    timer.Elapsed += new System.Timers.ElapsedEventHandler(send);
    timer.AutoReset = true;
}

public void send(object source, System.Timers.ElapsedEventArgs e)
{
    this.rtbMsg.AppendText("psyche-->" + receiver + ": hello\n");
}
