WaterMark using c#

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".

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

Note : This is Windows application using c#

If your OS is Vista or Win7, can't you make a create a window that toplevel + translucent + maximized? Then the entire screen can say "MAINTENANCE MODE" in large friendly letters.

Here's some C# code that might help. I think what you want to do is called "alpha blending". (Haven't done it myself.)

Here's some more.

This may be best, I'm not positive.

attach to the paint event of each form (maybe create a base form for all other forms to inherit)

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.paint.aspx

you can draw your image using the graphics object provided in the handler.

Take a look at the first answer with code here:
