Splash and password in visual c++ 6

Thanks budy, i got added splash and pass, could you please tell me how do i search in windows for a file, open it one by one, please tell me the source code

Let's start with Splash screen.  To do this you simply create a form that looks like you want it to and have your "main" show that form first, then continue processing your normal loading workload.  When the loading work is finished then hide the form and show your main form.
Authentication would be handled the same way, have your "main" method show a dialog that takes a username and password and authenticates the user, then proceeds from there.
