Hide mouse cursor for specific time

Question

public partial class Form3 : Form
{
    private readonly KeyboardHookListener m_KeyboardHookManager;
    private readonly MouseHookListener m_MouseHookManager;

    [DllImport("user32")]
    private static extern Int32 ClipCursor(RECT lpRect);

    [DllImport("user32")]
    private static extern Int32 ShowCursor(Int32 bShow);

    [DllImport("user32.dll")]
    public static extern bool GetCursorPos(out POINT lpPoint);

    [StructLayout(LayoutKind.Sequential)]
    public struct POINT
    {
        public int X;
        public int Y;

        public static implicit operator Point(POINT point)
        {
            return new Point(point.X, point.Y);
        }
    }

    public static Point GetCursorPosition()
    {
        POINT lpPoint;
        GetCursorPos(out lpPoint);
        //bool success = User32.GetCursorPos(out lpPoint);
        // if (!success)

        return lpPoint;
    }

    [StructLayout(LayoutKind.Sequential)]
    private struct RECT
    {
        public Int32 Left;
        public Int32 Top;
        public Int32 Right;
        public Int32 Bottom;
    }

    public Form3()
    {
        InitializeComponent();

        m_KeyboardHookManager = new KeyboardHookListener(new GlobalHooker());
        m_KeyboardHookManager.Enabled = true;
        m_KeyboardHookManager.KeyDown += HookManager_KeyDown;
        m_KeyboardHookManager.KeyUp += HookManager_KeyUp;

        m_MouseHookManager = new MouseHookListener(new GlobalHooker());
        m_MouseHookManager.Enabled = true;
        m_MouseHookManager.MouseDown += HookManager_MouseDown;
        m_MouseHookManager.MouseUp += HookManager_MouseUp;
    }

    private void Form3_Load(object sender, EventArgs e)
    {
        //ShowCursor(0);
        //MoveCursor();
    }
    private void HookManager_KeyDown(object sender, KeyEventArgs e)
    {
        label1.Text = e.KeyData.ToString() + " Pressed";
    }

    private void HookManager_KeyUp(object sender, KeyEventArgs e)
    {
        label1.Text = e.KeyData.ToString() + " Released";
    }

    private void HookManager_MouseUp(object sender, MouseEventArgs e)
    {
        label1.Text = e.Button.ToString() + " Released";
    }

    private void HookManager_MouseDown(object sender, MouseEventArgs e)
    {
        label1.Text = e.Button.ToString() + " Pressed";
        ShowCursor(0);
        MoveCursor();
        System.Threading.Thread.Sleep(5000);//5 sec   
        RestoreCursor(this);
        ShowCursor(1);
    }

    private void button1_Click(object sender, EventArgs e)
    {
        //RestoreCursor(this);
        //ShowCursor(1);
    }

    private void Form3_MouseMove(object sender, MouseEventArgs e)
    {
        //MoveCursor();
    }

    private RECT MouseTrap;
    public void RestoreCursor(System.Windows.Forms.Form ThisForm)
    {
        var _with1 = MouseTrap;
        _with1.Top = 0;
        _with1.Left = 0;
        _with1.Right = Screen.PrimaryScreen.Bounds.Width;
        _with1.Bottom = Screen.PrimaryScreen.Bounds.Height;

        ClipCursor(_with1);
    }

    private void MoveCursor()
    {
        // set the Current cursor, move the cursor's Position,
        // and set its clipping rectangle to the form. 
        this.Cursor = new Cursor(Cursor.Current.Handle);
        Cursor.Position = new Point(this.Left, this.Top);
        Cursor.Clip = new Rectangle(this.Left, this.Top, this.Width, this.Height);            
    }
}

I am developing one sample application My requirement is when user clicks on anywhere on desktop for example click on Windows "Start" button then Hide the cursor for 2 sec then show the cursor after 2 sec at the same position.

For that I have written above code and used Thread.Sleep(2000) for waiting but cursor position restores to Form's left.

Answer 1

you can achieve that using System.Windows.Forms.Timer.

Declare Timer on your form.

public partial class Form3 : Form
{
    private Timer timer = new Timer();

Set it on Form_Load

timer.Enabled = false;
timer.Tick += Timer_Tick;
timer.Interval = 5000;

When user moves mouse, instead of Thread.Sleep activate timer. When timer ticks (when specified 5000 milliseconds pass), Timer_Tick method will execute. In it, show pointer.

private void HookManager_MouseDown(object sender, MouseEventArgs e)
{
    label1.Text = e.Button.ToString() + " Pressed";
    ShowCursor(0);
    MoveCursor();
    timer.Start();
}

private void Timer_Tick(object sender, EventArgs e)
{

    RestoreCursor(this);
    ShowCursor(1);
    timer.Stop();
}
