I got this in ASP.Net but I want to use this same in classic ASP.

Sounds like you'll need to fire off an ajax call via a onkeypress javascript function call that calls a script which queries your database and gets data for user when it finds a match.

<input type="text" id="uName" name="uName" value="" onkeypress="getUserDetails(this.value)"/>

You can then use the data and further ajax to populate the additional fields.
