If you are using Windows, it is already built into the operating system.stober at 2007-11-9 13:02:56 >

How can I make Login App ?I search in security and logon Authentication, but It's seems all of them is for windows NT/2000, all I wanna do Is Login App for my Computer not to login for link to network.
I mean Login for using one computer, like usual Window Login only I want to add a few features.

Silent, silent... allways good questions, but often it is nearly "Mission Impossible" :cool: Ok, I want to start it like this: Everything that is not based on WinNT and i'ts security-architecture and is called windows is INSECURE.
There's in fact NO security-support under those versions. This means, that if your "opponent" has patience, time and knowledge there'll be no easy way to keep her/him from your computer... sad but true.
the only thing you can do, is to make it harder for her/him. Ok, there are several ways to lock the system completely, only allowing one app to work, some of them are "not very kind and clean" but who cares about that at login-state :-)
if you start your login app right at system-start, before any user action can take place, you will have the chance to put the system in such a locked state, and release it only if the user logged in correctly.
one crazy (but maybe colorfull) way to do this is maybe to put the display in DirectDraw exclusive-mode... but I dunno if this is it.
hope I gave a push in the right direction

Search in MSDN for GINA or MSGINA. This offers a way to implement the LogOn Screen by yourself.It will work onlx for WinNT bases versions (NT, W2k, XP)
