Assignment Scenario

Assignment 3: Implementation

Declare your Variables

A useful thing to do to before starting your serious coding is to declare all your variables in separate coding module.  If you have completed Assignment 2 part a you will already have a convenient list of some of the variables you will need. If not, make a list for yourself.

~~ Input Variables ~~

RectLawnLength

RectLawnWidth

etc.

~~ Stored Data Variables ~~

LawnSeedCoverage

LawnSeedInBag

etc.

~~ Output Variables ~~

AmountLawnSeed

NumBagsLawnSeed

etc.

It is likely you will need intermediate variables - used temporarily to hold results, e.g.

~~ Misc Variables ~~

AmountRectLawnSeed

AmountCirctLawnSeed

etc.

Before declaring your variables, you will need to add a VB module to your Project.

Your Task

Here are step by step instructions on how to declare your variables. You are going to declare all your variables inside a separate coding sheet called a module.

Module Coding Windows

1. If you have not added a module to your project already, then on the VB menu, click Project, then Add Module. A new white coding window should appear. You need to save the separate module just like you save a form.  Here is a picture of my VB explorer window showing two forms (input and output) and my module.

   

    

2. If you double-click the module you should get a white coding window. In the coding window, declare your variables like so...

etc.

~~Activity~~

Activity A
