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"
[Code]....
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
[Code] .....
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.

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.
View 4 RepliesIt 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
View 4 Replies"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

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.

When my form loads it adds some handles (using AddHandler) to a sub (showStatus). What this sub does is checks which control activated the sub (using sender.Equals) and displays text in the status label (status) accordingly.For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Selectwhere: tbOne is a textbox, status is a StatusLabelIt gives me an error though, saying "Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.TextBox'."Any ideas on how I can get this to work with a select case statement?

i have a program using a select case to convert letters to special charaters. My question is how can I get the code to read upper and lower case letters without having to put the upper case letters in my select case statement. Example: Part of my code is
[Code]...
Is there any specific reason why camel casing examples often start with a lower case letter?
E.G:Dim btnSave As New Button
'as compared to.>>
Dim BtnSave As New Button
Is it to make a distinction between the ( object / variable ) and its TYPE?
Why then does the IDE not add items starting with a lower case letter if lowercase initial lettering is more common or more accepted?
ive got a form containing treeview on the left docked, and two panels one over the other (just as for practice), so i am using treeview to select one from the other the code contains the Case select,

View 7 RepliesI have a listview filled with single letters as the text. How do I get the listview_keypress event to select the appropriate letter in the listview when that letter is pressed on the keyboard? The listview has focus, and I can even msgbox e.keychar to see it is getting the proper letter. But how do I get it to select that letter as if it were being double clicked?

View 7 RepliesI'm working on a routine that requires a significant amount of nested and daisy-chained logic. Using If-Then-Else, each logic construct would run 8-15 lines of code (quite readable) while using Select Case each construct doubles that (even with significant commentation, it gets less and less readable with each new Case).
I've read many times in this forum how Select Case is leaps and bounds ahead of If-Then-Else in runtime performance, although I can't recall any discussion of the underlying process(es) that make it so. I've also not had any luck finding good, detailed documentation on the nuts and bolts under each logic construct. What I'm working on, if the performance leap is legit, needs the performance more than the readability but if the performance is marginal then the readability is going to get the priority. how and why Select Case is supposed to process so much faster than If-Then-Else. Links to good white paper would be really nice too.
I have a macro that uses "If Then" to choose what macro to run based on the ActiveCell. I would like to use the Select Case method instead. How would I change this code?

I am using visual basic in VS 2008 and trying to learn how to assign a value to a word in a combo box using case select, this is my first attempt at programing and i just can't work out what to do next. So far i have two combo boxes a label and a button, i want the word, first to = 11, second = 9, third =7, fourth = 5. All it is doing at the moment is adding the list index value and displaying that total in the label. I want it to display for eg: if (first=11) and (second=9) are selected a total of 20 in the label,and so on for what ever combination is selected.

I have assigned nodes in my treeview keys depending on what they are to do with and now i would like to use a select case to choose the right calculation depending on which node is selected.i have tried selecting the key like this:

Case Is = "assi06"
Call MinimumSpeeds()
but option strict on dissalows conversion from string to integer. there are more cases, but i have only shown one here. How can i code so that the key is selected from the selected node?
I had to change the given code from If Then to Select Case, and this is what I came up with. But when I run the program, it does not work and gives me zeroes instead of the correct information.
