Creating a blue screen

[IanG Surreal Studio]

Hi, I am interested in how different companies manage to create a blue screen which halts the operation of the computer until it does what it wants to. For example Symantec, the people who create Norton antivirus, create a blue screen when you rename your hard disk; and there is another company who actually stop the booting of windows to bring up a screen where it does registry defraging. So how would you create something like this? Thanks, IanG

So to do it you would have to create a driver, is there any other way without the use of drivers?

I don't know, you'll need to consult the DDK and check out the docs. --Mike-- Visual C++ MVP :cool: LINKS~! Ericahist | 1ClickPicGrabber | NEW~! CP SearchBar v3.0 | C++ Forum FAQ #include "witty-quote.h"
