Question

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#

Answer 1

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.
