Email passwords

I am desigining an intranet site using vb.net/asp.net. The sql - users table has a username, password, e-mail address and date field (date is for when the user last updated there password). My login page etc is working fine, but what I want to do is when someone types in the wrong password, to send an email to the address from my users table giving them the correct password. I am not sure how to go about doing this and would appreciate any advice on this.I am desigining an intranet site using vb.net/asp.net.

Won't that be a bit dangerous and a security risk?
To E-mail the password when the user typed it wrong?
What if His/Her significant other or a friend or a neighbor takes a peek at the e-mail?
