Billing
by Tau

Purpose:
This will analyze your billing summary and determine how many hours and minutes each screen name on your account has been online since the last billing date. I wrote this code a while ago, so its not written as well as it could be written. It works though. To make this work the Billing Summary window needs to be open. That is the window that has all the screen names on your account and the different amounts of time each have been on.

Requirements:
This code requires a ListBoxs named lstFinal, lstNames, lastNumber, a textbox called txtInfo, command buttons: cmdCalculate and cmdCopy.

System:
This code will function on Visual Basic versions 5.0 and 6.0, is to be used with no BAS file, and on America Online versions 4.0 and 5.0
