Add new feature to my vb6 app

I have a? small application written in vb6 that? reads in data from? a mdb file, calculates? all of the values, and then? gives me the values. It also allows? for manual entry of data.? I need this application modified so that it will allow me to also read in CSV files and calculate the values just like it does with the mdb files. Some of the CSV files will be layed out a little differently than others so I need a way to map the values to the correct location.
