Create a single subdirectory containing all three portions of the assignment. There will be multiple files for each program, including at a "Project" file (xxxx.VBP), a "Project Workspace" file (xxxx.VBW), and probably a text-processing file describing the form (xxxx.FRM, xxxx.WPD, or something like that).
Turn in all three parts as a single unit by using WinZip (available on all the CS NT's) to package up the entire directory into a single file for submission.
