    public int flags; 

    public IntPtr hCursor;

    public Point ptScreenPos;

}

[DllImport("user32.dll")]

static extern bool GetCursorInfo(out CURSORINFO pci);

private const int CURSOR_SHOWING= 0x00000001;

private void button1_Click(object sender, EventArgs e)

{

    CURSORINFO vCurosrInfo;

    vCurosrInfo.cbSize = Marshal.SizeOf(typeof(CURSORINFO));

    GetCursorInfo(out vCurosrInfo);

    if ((vCurosrInfo.flags & CURSOR_SHOWING) != CURSOR_SHOWING) return;

    Cursor vCursor = new Cursor(vCurosrInfo.hCursor);

    Graphics vGraphics = Graphics.FromHwnd(Handle);

    Rectangle vRectangle = new Rectangle(0, 0, 32, 32);

    vGraphics.FillRectangle(new SolidBrush(BackColor), vRectangle);

    vCursor.Draw(vGraphics, vRectangle);

}
