C# - Question about events (also textbox clearing and starting/stopping a timer)

Hi all,

I basically have a System.Timers.Timer that is set to trigger an event every 10 seconds. In the event, I usedtextbox1.Clear(); so that every time the event is triggered, the textbox clears. Unfortunately, this does not work. I also triedtextbox1.Text = ""; but it still does not work. The textbox is not clearing. Any idea why this happens?

In the beginning of the event, I also wrote this line: myTimer.Enabled = false; to temporarily stop the timer when the event starts. I also wrote this line:myTimer.Enabled = true; just before the event ends to start the timer again. Basically I don't want it to start/trigger the event again while the event is not yet finished executing. Is it okay to do this? or is there a better way to do this?

Here's a snippet of my code:

public partial class Form1 : Form
{
        public Form1()
        {
            InitializeComponent();
        }
        System.Timers.Timer myTimer;

        private void Form1_Load(object sender, EventArgs e)
{
    myTimer = new System.Timers.Timer();    // Create a timer
            // Tell the timer what to do when it elapses
            myTimer.Elapsed += new System.Timers.ElapsedEventHandler(someEvent);
            // Set it to go every 10 seconds for example
            myTimer.Interval = 10;
}

private void someEvent(object sender, System.Timers.ElapsedEventArgs e)
{
myTimer.Enabled = false;
// do stuff here
/////textbox1.Clear();
myTimer.Enabled = true;
}
}

Please let me know. Thanks

EDIT: I added snippet of my code. I also tested textbox1.Clear(); on a button click event and it works. But it does not work when textbox1.Clear(); is in the event.
