Crystal report problem

Hi ..I have a bit of a problem.
I want my crystal report to display the information of a specific person (e.g. student, like when you print a student's academic record). I want it to display the information of a specific person instead of taking all the records that are in the database.
What I do is that, I search for the person in my windows application (using their surname) and I want to transfer the information to the crystal report viewer...

Like this:

Student No Surname Initials Class
2365565 Moloi J Grade 1 A

Please help

By da way I'm using Visual studio 2003use record selection formula
or
pass parameter to report to use in report query
