CIS 115 Introduction to Problem Solving and Programming
Instructor: Overstreet
Lab 3 (VB - Application)
Due: Week 5 - Friday, February 13
Create a Windows-based application that will calculate the Gross Pay earned for a worker, given
the number of hours worked and hourly pay rate. Let user choose when to close/exit the
application. Be sure to place the text “CIS115-???_LAB3_‘your full name’ ” in the title bar of
the form.
For this exercise, you will submit your completed solution page (inputs, outputs, processes, TOE
Chart, algorithm and test design), a printed copy of your Visual Basic Application (a screen shot
of your running program), and a printed copy of your code. If you do not include the completed
solution page and both the screen shot and the code, your assignment will be counted as
incomplete.
Staple your grade sheet (on top), the solution page, the screen shot, and the code together and
make sure to write your name, jnumber and section number at the top of your grade sheet. No
envelope necessary.
