Hide mouse cursor after an idle time

Question

I want to hide my mouse cursor after an idle time and it will be showed up when I move the mouse. I tried to use a timer but it didn\'t work well. Can anybody help me? Pleas

Here is a contrived example of how to do it. You probably had some missing logic that was overriding the cursor's visibility:

public partial class Form1 : Form
{
    public TimeSpan TimeoutToHide { get; private set; }
    public DateTime LastMouseMove { get; private set; }
    public bool IsHidden { get; private set; }

    public Form1()
    {
        InitializeComponent();
        TimeoutToHide = TimeSpan.FromSeconds(5);
        this.MouseMove += new MouseEventHandler(Form1_MouseMove);
    }

    void Form1_MouseMove(object sender, MouseEventArgs e)
    {
        LastMouseMove = DateTime.Now;

        if (IsHidden) 
        { 
            Cursor.Show(); 
            IsHidden = false; 
        }
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        TimeSpan elaped = DateTime.Now - LastMouseMove;
        if (elaped >= TimeoutToHide && !IsHidden)
        {
            Cursor.Hide();
            IsHidden = true;
        }
    }
}
