change the windows opening screen

hello, I'm writing an application which has to be executed before the windows desktop appears.Can you help me to come out of this problem. thanks

To my knowledge it is not possible to tell the Win32 system when to start any given application program. You could write an NT Service program, which normally starts before login, or a Win32 Kernel program which probably starts before Service programs. To write either of these you need lots of systems program experience and study several books. Check out Advanced Systems Programming that, I think, was written by John Riche. I attended one of his seminars once a few years ago, and he has got to be the world's most knowledgable person about Win32 operating system. His books are worth their weight in gold.

On NT, you'll need to write a service. There are a couple of articles on NT services here at this site. On 9x (and I assume Me as well), you need to add your app to the HKLM\SW\MS\Win\CV\RunServices key. Look up the RegisterServiceProcess() API for more details.

That would be Jeffery Richter, not John Riche. http://www.wintellect.com/richter\_bio.html

While I don't know what you app is take a look at the following topic in MSDN - seems very interesting and it might allow you to do some interesting things: GINA DLL Interface API
