C#

public KeyStatusStatusBar(bool CapsLock, bool NumLock)
{
 // This call is required by the Windows.Forms Form Designer.
 InitializeComponent();
 ...
 Application.Idle += new System.EventHandler(OnIdle);
}
...
[DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true, CallingConvention=CallingConvention.Winapi)]
public static extern short GetKeyState(int keyCode);

public void OnIdle(object sender, EventArgs e)
{
 // Update the panels when the program is idle.
 bool CapsLock = (((ushort) GetKeyState(0x14 /*VK_CAPITAL*/)) & 0xffff) != 0;
 bool NumLock  = (((ushort) GetKeyState(0x90 /*VK_NUMLOCK*/)) & 0xffff) != 0;
 if (CapsLockPanel != null)
 {
  CapsLockPanel.Text = CapsLock ? "CAP" : "";
 }
 if (NumLockPanel != null)
 {
  NumLockPanel.Text  = NumLock  ? "NUM" : "";
 }
}

I USED THE FOLLOWING CODE IT WORKS FINE BUT NUMS LOCK WORK FOR ONLE ONCE i.e if my nums lock is off IT SHOW NUMS IS OFF BUT AFTER THAR IT SHOWS THE SAME STATUS
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if ((e.KeyCode & Keys.KeyCode) == Keys.CapsLock)
{
if (Control.IsKeyLocked(Keys.CapsLock))
this.toolStripStatusLabel3.Text = "Caps is activated.";
else
this.toolStripStatusLabel3.Text = "Caps is Deactivated.";
}

else if ((e.KeyCode & Keys.KeyCode) == Keys.NumLock)
{
if (Control.IsKeyLocked(Keys.NumLock))

this.toolStripStatusLabel5.Text = "NumLock is activated.";

else

this.toolStripStatusLabel5.Text = "NumLock is Deactivated.";

}

}
