9/3 → 9/7
Chapter 2 - Visual Basic Controls and Events
(Most of these notes are hands on stuff so I'll do a demo in class and probably go through these quicker than usual)
- Controls and Events
- Make sure you read this chapter carefully it covers fundamentals that are the building blocks of everything else.
I'll go over an example of a small program.
I Need Some Volunteers for a Study!!!!!

Do some exampes in Class,
In-Class project, try #4 page 100, Conversion program. Or something from that list of exercises.
9/10 → 9/14
Chapter 3 - Variables, Input, and Output
What is Critical Thinking?
Blooms Taxonomy
Start the Hands-On Programming Example
- Very important chapter
- Talk about strings
- Bring in Questions!!
Continue with the Hands-On example
In-class example :Compound Interest
- A = final amount
- P = principal amount (initial investment)
- r = annual nominal interest rate (as a decimal)
- n = number of times the interest is compounded per year
- t = number of years
Maybe to # 3 Page 155 in class as a continuation of this project.
9/17 → 9/21
- If Statements
- Case Statement
- Boolean Math
- Calling other event functions
- Making one function handle more than one event
Let's try a problem requiring a decision in class:
9/24 → 9/28
Chapter 5 - General Procedures
- Sub Procedures
- Function Procedures
Review for Exam
Exam 1 - 9/28
Will be on:
- Chapters 1 thru 5
- If Statement
- Functions
- Procedures
- Boolean
- Case Statement
10/1 → 10/5
- Loops
- Do While
- Do Until
- For - Next Loops
Let's start a project today that will use loops for your take home project next week:
We'll write a program to run a linear regression using least-squares:
What is that? This is a way to predict or model data where it is thought that one variable effects the other. (Independent variable → dependent variable)
This is done by taking known pairs of data where is looks at though there is a correlation and applying it to a clalculation.
Write a program where the users enters in two pieces of data (paired) into a list box per line separated by a comma. (You can change this if you want; may be easier to have 2 list boxes) Grab that data and run the least-squares approximation formula.
Formula: (see below because this box is too small)
Ok, so you all know that a straight line uses the form y=mx+b where m is the slope and b is the y-intercept.
You are going to use the formula below to get the m and b
Then provide some input for the independent variable (m) and you tell the user y. Y will be the predicted correlated value for m.
For example, If I gave you 30 pieces of paired data that is height and weight, then I put in a a height into an input box, click the button, your program should predict this person's weight.
10/8 → 10/12
m= (n*(sum of xi * yi) - (sum of xi)
* (sum of yi)) / (n * (sum of xi * xi)
- (sum of xi)2 )
-- or --
b = ((sum of yi) - m * (sum of xi))/n
-- or --
Make a functinons for:
-
sum of xi * yi
-
sum of xi
-
sum of yi
-
sum of xi * xi
-
(sum of xi)2
10/15 → 10/19
- More organized way to store a lot of related data
- Some consider this the most complex topic of the course.
- Not that hard, just another way to store a lot of related data.
Extra ->Class example of the American to British Translations
Dictionary.txt
Text file for the 2-d array example: NumOfStudents.txt
|
The Image Editor
Project: ZIP files where you can get sample PPM files |
Array example in class. ->
- Load states and their abbreviations into an array of records
- display
- find something
-Save the states.txt file to the bin folder in the debug folder in the project folder.
Project->bin->debug->put text file here.
------------------------------------
Let's compute the average of a list of numbers. Make sure you load the numbers into an array first. Then loop again and determine the average. We are using an array as practice.
List of Numbers
Maybe:
We can work on sorting
Write a simple program that sorts a file, we can use the egg file from way back, Use either bubble or selection sort.
Eggs.txt
Example implementation of an array of Records.
10/22 → 10/26
Chapter 8 - Text Files
Let's edit the Justice program, add some new features.
This week I also want to make sure we've practiced the Try-Catch block.
Let's do an old exam I dug up, I want you to give it an honest try first.
If there's time let's assume they are not sorted, and we need to sort them first.
10/29 → 11/2
Let's do a practice exam:
Load this file into an arrray of
strutures: Famous.txt
- Read the data in, put the name in one list box, the date
in another list box
- Make a button that puts just the
people born in the 70's in the 2nd list box
- Button that
displays their name and ages together in the 2nd list box;
sorted by birth date
Exam 2 - 11/2
11/5 → 11/9
Chapter 9 Additional Controls and Objects
Multiform Projects
Do an example in class of a project with a database connection
11/12 - 11/16
Download:
Megacities
11/19
Thanksgiving Break
11/26 →11/30
Continue with Chapter 12 - Web Applications
You will notice a WWW folder in your directory on the cs domain. Put any of your web applications there. Don't make any subdirectories other than the ones VB creates on its own.
The URL for the your web pages will be:
http://csci207srv.cs.edinboro.edu/USERNAME
Continue working on the web application
Your web.config file uses
the targetFramework="4.0" attribute, which isn’t supported under IIS 6. In order
to upgrade to IIS 7, the server must be upgraded from
Windows 2003 to 2008.
remove the attribute from
the web.config file for the directory you specified
below, and it should work.
Final Exam: December 12th 10:15 → 12:15 (Final Exam)
