Quick Shortcut to Lock Workstation

Console Version

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace QuickLock
{

       class MyComputerLock
      {
            [DllImport("user32.dll")]
            public static extern void LockWorkStation();

             static void Main(String[] args)
            {
                     try
                          {
                                 LockWorkStation();
                          }
                          catch (Exception ee)
                         {
                               MessageBox.Show(ee.Message);
                          }
              }
       }
}

Alternatively,if you put the code in Windows Form and you can customize the App.ICO to some friendly ICO file which will showup in QuickLaunch bar instead of the old rectangle which shows up for an EXE.
