Homework Assignment HWA 05 II
Bookstore Project Design
- Form 3 Transaction Selection Form
(Note: Homework problems are to be turned in to the instructor, not the lab assistant.)
Objectives:
Everything about this assignment is a repetition of HWA 5I, except it pertains
to Form 3, the Transaction Selection Form. Most of what you would
normally be expected to do has been done. The form has been provided and
the objects to be manipulated have been identified and documented. The
most important thing you need to do here is outlined in Sections A and B
below. Before doing this, I strongly urge you to review the list of
attributes and methods associated with each of the classes indicated in the
Bookstore Project Specifications. Otherwise, you may find yourselves
redoing work that has already been done. (The more familiar you are with
the methods in the classes we have, the better equipped you will be to refer
to them in your diagram and use them in your code.)
Once again, you will find that data validation and recovery are the hardest part of your work. So you will want to pay particular attentions to these details.
Reading (same as for HWA 5I):
Homework
Assignment:
A. Write out detailed Behavior Diagrams for the code behind for the Transaction Selection Form. There will be no "redo" of these diagrams so they need to be in good shape when submitted. Your diagram must include the validation of all input (including from the current Book File), recovery from user data entry errors, and indications as to when important controls are enabled (or made visible) or disabled (or made invisible).
B.
Write the code behind for this form. Test it,
including validating user input (most important) and checking to ensure valid
input from the currentBookFile.
