WaterMark using c#
<p>I am working on a Kiosk application. There is a Maintenance mode in my application. When my application enters into Maintenance mode, i want to show the user a watermark "Maintenance Mode Commenced".</p>

<p>I want this watermark to be shown through out my desktop. No matter what form is in focus. Is this possible ? Any ideas.... </p>

<p>Note : This is Windows application using c#</p>
