Suppose a teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores.
Test Score Letter Grade
90-100 A
80-89 B

Using VB.NET write a program that can calculate the grade of a student based on his or her marks in five subjects as input according to the following rules:
Grade A: For average between 100 and 80 (inclusive)
Grade B: For average between 79 and 65 (inclusive)
Grade C: For average between 64 and 40 (inclusive)

It works up to this point but when I try to add so that 70-79 is a C, 60-69 is a D, and 60 and less is a F I run in to problems.

I am in a visual basics 2008 class for my MIS degree. This is the beginners class. We were instructed to build a program that calculates a score average. However, we get extra credit if we figure out how to drop the lowest test score. I do not know how to do this. The teacher won't help with the extra credit. I will post my code.

I have a homework assignment to code an application that allows the Prof to display a grade based on the numnber of points he enter. The grading scale is : 0-299 -F; 300-349- D; 350-399- C; 400-449- B; 450-500- A. We are to store the minimum points in a 5 element one dimensional Integer array name intPonts and store the grades in a 5 element one dimensional String array name strGrades. The arrays should be parallel arrays. The procedure should search the intPoints array for the number of points entered by the user and then display the corresponding grade from the strGrades array.
I have stored the minimum points and grades in a one dimensional integer and string array respectively. I have coded the program, and when I put in random points, it gives me the letter grade. For example, if I put in 376 it will display a "C"; if I put in 200, it will display an "F". However, if I put in anything over 449, it will NOT display an "A", it just leaves the lbl blank. I am stumped on how to get the code to read pass 449 points.

Write a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
View 1 RepliesI'm trying to code a program that averages a grade from a list box, but the numbers in the second list box could change, so not sure how to code that. It should list the letter grade and the average, then if they don't enter a grade, should tell you to enter a grade first before hitting the average button.

Microsoft is trying to assure that it loves VB and VB programmers and wants them but in reality the opposite is happening. All code samples either from Microsoft or third party developrs portrait C# code. For the same reason C# programmers are challenging VB Programmers in every field.
View 5 RepliesI am trying to make a simple program that utilizes lists, loops, arrays, and multiple forms. I started the program in which I have incorporated lists and loops already.A summary of my program; I am trying to be able to add a name to a combobox list, and assign a grade to that particular person (grade of A = 4, b = 3, ect ect). I am assuming I should utilize the array concept at this point when assigning the grade to the name, but I am not exactly sure what to do. I have attached a screen shot of my form, and I will post what code I do have so far.Also, when all the grades are entered with their corresponding names, I want to also have a summary screen pop-up with the names and which grades they received, plus the average.[code]

View 2 RepliesI ma trying to create a program to calculate my math grade. The way my math teacher explained the grading scale was each test is worth 1 point and each quiz is worth .2 points.
So as an example (add both sides up then divide by both sides)
100 =1
80 = 1
15 = .2
18 = .2
213 divide by 2.4 which equals your grade of 88.75
There are more quizs and tests in the semester and I want the numbers to change with the number of quizs and tests entered. The only problem is I am not sure how to code it. I though I would use IF AND statements but I am not sure where to start.
How do you enter in a code for an overall letter grade from a percentage given? I have a seperate box for the letter grade and a seperate one for a the percentage grade . I have it setup when an overall grade and possible grade is entered into boxes it will give me a grade percent but not a letter grade. How is that added? I am doing this for my course project but dont undersatnd the coding very well. I am just trying to pass the class.
View 1 RepliesI need someone with patience and can go through a solution with me from the Clearly Visual Basic book. I'm good with computers and can usually learn things relatively fast on my own time and in my own way, but I'm going to school for computer programming and, with certain things, I learn better with things explained to me rather than reading from a book. If someone has the time to go over this solution I'm doing and explain it to me in a way I'd have a better chance of understanding, I'd be truly grateful. I need a tutor, for lack of a better word. The lab I'm doing is from the Clearly Visual Basic book and the instructions are:
Code an application that displays a letter grade based on the averages of three test scores. Code the application using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B. If the average is at least 70 but less than 80 the grade is C. If the average is at least 60 but less than 70, the grade is D. If the average is below 60, the grade is F.

Write a program that reads in a set of grades for a class.The program takes in the number of students in the class from the user. When the Get Grades button is clicked the program then reads in a grade (0-100) for each student using an inputbox. The program should then display the percentage of students who pass and the percentage of students who fail.The program should call a function to calculate the average grade for the class. Then finally the result is then displayed.

I have been struggling with my programming class from day one. I still can't seem to grasp the complete logic on how to write code. Anyhow, I have an assignment due that I am stuck on. Here is the assignment:
In this exercise, you code an application that displays a letter grade based on the average of three test scores. Open the Grade Solution (Grade Solution.sln) file, which is contained in the ClearlyVB Chapl8Grade Solution folder. Code the application,using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B.If the average is at least 70 but less than 80, the grade is C. Tf the average is at least
60 but less than 70, the grade is D. If the average is below 60, the grade is F.
You will be developing the code for the function on your own. Below the Public Class frmMain line, insert this function header:Private Function CalculateGrade(ByVal testScore1 As Decimal, ByVal testScore2 As Decimal, ByVal testscore3 As Decimal) As String
In the function, declare variables for the average score and the letter grade. Calculate the average, use IF/Elself statements to determine the letter grade, and return the letter grade. Create a subprocedure for the Click event for the btnDisplay button. It should call the CalculateGrade function with three arguments ( the three test scores from the text boxes), and display the returned value in the lblGrade box.

My code will only let me typ one number into the text box and then it brings me back to the code and says "stack over flow exception was unhandled.
The exercise prior to this one had us use two parallel arrays that store a letter grade (A, B, C, D, F) and the minimum points needed for each grade. The user input the points earned by the student and the program shows their letter grade. It took a minute, but I got that one done, and it does what it's supposed to do.This exercise has us modify that exercise to ask for the (via InputBox in MainForm Load event) total points possible. The grade is then determined by percentage of the total points possible. For instance, if x is the user input, an "A" would be 90% of x.

I have to write a program using 2 parallel arrays representing grade point and grades. The grade points range from 0 to 500, however, we are only to use the minimum points per each letter grade in " points " array. This is shown in the code below. You then enter a number from 1 to 500, representing the grade points, and in turn it spits out your letter grade.My problem is this. When I enter a number, say 200, I get a letter " D " grade instead of an " F " grade. It appears that every number range I enter gives me one letter grade less than what it is supposed to be. Also, any number 450 to 500, representing an " A " grade does not even register in my Grades Label.

I'm looking for a book that is pretty much A-Z for LINQ programming from Visual Basic. I am particularly interested in LINQ to SQL. I've found "Programming Microsoft LINQ in Microsoft .NET Framework 4" and while its description sounds interesting, there is no discussion on the book at all . Do any of you have any experience with this book? If so, what do you think of it?

my problem is that i cant properly sense the audio of the software. i am using windows 7 and vb.net. i have done a good amount of research, but i have not come up with an answer.
i am almost positive that i need to intercept the win32api call of the software to trigger the mute that i will use. i dont know how to do this, all the information i can find that is even close to this subject is for 98, nt and 2k.
does anyone know of any books (or websites) that contain information on this subject?
