Application,using A Function To Determine And Return The Letter Grade?
Jun 3, 2011
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.

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.
Module Module1
Dim Average As Integer = 0
Dim Response As String = ""

I have coded this not sure how to get it to display correctly to the lblGrade box. I have set it up for. Supposed to take the average of three grades and display the letter grade for the average of the three grades.
Here is the code
Public Class frmMain
Private Function CalculateGrade _
(ByVal txtTest1 As Decimal, ByVal txtTest2 As Decimal, _
ByVal txtTest3 As Decimal) As String
Dim AverageScore As Double

I made an application that calculates course grades. The program runs perfectly except for the last part
The the final grade number comes from the label "lblCoursePts" and i want to put the letter grade in the label "lblFInalGrade" Here is what i have.
'Determine the final letter grade
Select Case lblCoursePts.Text
Case 90 To 100 : lblFinalGrade.Text = "A"

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.

I 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.

I am taking an online class and I am having trouble getting my solution to work. My assignment is as follows: In the function, declare variables for the average score and the letter grade. Calculate the average, use If/ElseIf 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.I have looked all over the internet and have had no luck finding an example to look at I am taking an online class and I am having trouble getting my solution to work.

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.

It is meant to average 15 user-input grades and then from there I have to provide the letter grade that corresponds with the average percent. I understand how to provide the corresponding letter grade, but I don't understand how to get the average. I've tried putting it into arraylist format

"I need to create a program that will allow the user to enter in 10 test grades from a class. I need to store these grades into an array, and use a loop to add up the total. Then I'll need to output the average, and the letter grade for the average using:
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D
Below 60 F"
That's all it needs to do. Here is some code that shows you that the only thing I know how to do is (allow the user to enter in 10 test grades from a class.) The rest I'm so lost on and have a crappy instructor. This assignment is due tomorrow, but the instructor is not available over the weekend.

I'm developping an ASP.NET application, and I need to use an old VBScript file that would be really hard to translate into pure VB in a VB function.
This VBScript is supposed to return an array that I'd like to use it in the VB function that called it.
How could I call the VBScript function in my VB application and use the value it returned?
I've search how to do so through many forum and FAQ, but it seems that these results where mainly focused on old version of the .NET framework.[code]...

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.
Public Function GetPassRate(ByVal intGrade As Integer) As String
Do Until gradeCounter >= NumericUpDown1.Text
If intGrade >= 40 Then[code].......

I am new to VB and playing with a program to display disk info attached to my PC. I have used WIN32_DiskDrive & WIN32_LogicalDisk to gather info regarding volumes, disks and partitions.
What I want to find how is how to relate the Device Index and Partition # back to a volume (ie with a drive letter).

Ok, basically, I need to know what the current hard drive letter that the current user is using, along with the user's name, followed by Music. When using the command prompt, we can use a simple code that is just %currentuser%Music but, I guess Visual Basic is a bit more complicated. Haha.
If you're curious why I need this, it is because I am making a program for my company to help backup our music and documents from their computers before we get new computers.
When using the code above in the command prompt in Windows, you would get something like: C:UsersRobertMusic, but this does not work for Visual Basic 2008.
My current operating system is Windows 7. I can supply more information if needed.

Im making a login system that encrypts and decrypts the username and password. My encryption code is:
Private Shared Function enc(ByVal targetString As String, ByVal maskvalue As String) As String
Dim Index As Integer = 0
Dim ReturnValue As String = ""
[code]....
The enc function works for both encrypting and decrypting (I've tested with a MsgBox alert. The problem I'm having is when the program loads, it reads the file and decrypts it. However, instead of properly working, it returns one character in the first textbox and nothingin the other without any error being thrown.

Just so it's known, this question is mostly academic, even though I tried to use the concept in a real-world solution. I realize the example is contrived, but I believe the concept is valid.I want to write some fluent code like this:
[code]...
I realize that I can't force an anonymous type into a specific type (like implementing an interface or some other class), and I don't want the overhead of defining a specific class just to match my desired fluent name with the actual method name. So I was able to make the code work like this:
copy(my_first_file).to.Invoke(my_second_file)So there is no IntelliSense or type awareness there, and I have to include the Invoke in order to have the method run. How can I get more type safety and exclude the Invoke method, under these constraints: Anonymous Type returned from Method No additional classes or interfaces Preferably, I do not want to pass in another parameter to the copy() method that tells what type to return, unless copy becomes a generic method (but I think that means defining another class/interface, which I don't want to do)

First off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

In my program i use a function to determine which card to play:
Private Sub hogere_kaart(ByVal klr$, ByVal splr, ByVal uitkomer)
(hogere_kaart= higher card, klr$=color, splr= player, uitkomer= the one who started the round)
In a former version of Visual Basic I did not have the problem that splr and uitkomer are not accepted: I get the message "All parameters must be explicitly typed if any of them are explicitly typed". Declaring them at the start of the code in DIm statements does not help.

I am a vb newbie having some trouble with an assignment. A user enters a letter into a text box, and the output must make the letter uppercase and tell what position the letter is at in the sentence "The quick brown fox jumps over a lazy dog."
Here is my
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[CODE]...............
This is what comes out: "A first occurs in position -1". Everything comes out except the position is always displayed as -1.

Is it possible to change to colour of letters as they are typed.I.e
Piece of text says
"Hello World"
when user types "H". The "H" in the original would change if matched and then so on and then when "Hello" is matched it would change to another colour.

take a look at the following Code:

[Code]....
The Funtion ZZNull always returns Nothing, so IsNothing(d) in the calling method should evaluate to True.
But it does not !
When you run these lines, then you will see that IsNothing(d) evaluates to False
