>2) I develped a program to display certain records on screen using grids before they are printed out. now i find
that i have to filter the records shown on the grids according to certain dates. after that, i'm also supposed to let
the user select which records they want to print out from the filtered list. I'm really confused as to how i'm
supposed to let them select the records from the grid? is there any other way i can let users select random
records from a table other than grids?

<< You could add a column to the grid and put a checkbox control in it. The user could check the records he want
to print.>>

i understand what u are trying to teach me here but how do i specify that "this" checkbox is for "this" record?
