Hiding the form from alt-tab menu

This is a UI tweak for hiding the form from alt-tab menu.

protected override CreateParams CreateParams
{
   get
   {
      CreateParams cp = base.CreateParams;
      cp.ExStyle |= 0x80;
      return cp;
   }
}

Edit:
In order to make it work, you have to use Me.ShowInTaskbar = False

Description:

WS_EX_TOOLWINDOW bit is turned on by OR-ing ExStyle with 0x80.

The following always works,

Me.FormBorderStyle = FormBorderStyle.SizableToolWindow;
Me.ShowInTaskbar = False;

But if you have a borderless form, i.e., FormBorderStyle.None then ShowInTaskbar = False doesn't work. So, we should set the WS_EX_TOOLWINDOW to true in addition to Me.ShowInTaskbar = False.
