Exercise On Sub Procedure To Calculate The Average?
Jun 22, 2010
Write a program to calculate the average of three exam marks. The input and output should be done by subprograms GetMarks and DisplayAverage respectively. the calculation should be done by a function, CalcAverage. This is my code:
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Dim student As String, exam1 As Integer, exam2 As Integer, exam3 As Integer
Dim average As Double
lstResult.Items.Clear()

I have text1=a, text2=b, text3=c, text4=d, text5=e
Now I want to calculate the average of the values,
Here's a simple way
average=(a+b+c+d+e)/5
But what if i have values only in 3 textboxes, that means the code will still divide the sum of the values into 5, that will not be correct!

My objective: to check the remaining btns in play and obtain the cash prizes in the remaining btns then calculate the average. It may seem simple but it actually isn't.
Here is what i have so far:
Private Sub btncase1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btncase1.Click
If usercase = 0 Then
usercase = btncase1.Text

I have a spreadsheet that has two columns (A and B) - Column A contains Month/Year and column B contains sales. I would like a bit of vba that will look in column A to find the month/year then calculate from column B the average sales for that period. So for example:
Date Sales
Jan 11 500.00
Jan 11 250.00
Mar 11 152.00
Apr 11 116.00
So in other words there can be a number of lines with the same date/year and the code will need to identify these and average all sales from column B associated with that particular date. I would like the output to appear in a summary table showing the total average sales for each particular month - perhaps this could be output to a new sheet?

I'm in a bit of a pickle. I'm new to Visual Basic and I have been writing a simple program to rate movies. I'm stuck on calculating the average from the text file. The text file holds the numbers from 1 - 10 (ratings). I want my program button to add all the values from the text file and display the average from the total amount of ratings and display them into a text box.

I'm trying to write a program that allows the user to enter 10 numbers into an input box and then the program will use a function to calculate the average of those numbers. I'm really illiterate when it comes to Visual Basic.

This is the current incarnation of what I have:
'Program: Ch4E4.6
'Programmer: Jeff Pannell
'Date: October 1, 2009
'Description: This will allow for entry of a worker's name and the number of pieces completed. The program will then calculate a pay rate, but also determine an average and summarize number of pieces made, total pay and an average pay per person.
Public Class PieceworkForm
'Declaration of modular-level constants.
Const PIECE_RATEA_Decimal As Decimal = 0.5D
Const PIECE_RATEB_Decimal As Decimal = 0.55D
Const PIECE_RATEC_Decimal As Decimal = 0.6D
[Code] .....
So, my problem is that whenever the form is executed..a user would type in a worker name, and the amount of pieces made. I get a dollar amount earned and then a total pay, though they seem to be the same. More than likely I've got some sort of bad logic in there mathematically.

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 trying to code a program in vb.net that will calculate the predominant or average colour in an image file and then change the fillcolor of a rectangle to that predominant colour. I want to do that by getting the RGB value of each pixel, adding them up and then dividing them by the total number of pixels in the picture. This is the code that I wrote to do that.

I am a beginner programmer so this is basically the second time I fired up VS (not much experience). I searched the internet for the last hour but found nothing that might help me. I made sure every value is positive and changed all numerical variables from integer to decimal and I still get the error.I have absolutely no idea why this doesnt work but if I remove the "for" loop then the line written in bold works just fine.BTW this is my first post so scuze any mystakes I probably made.

I have created a class called Student, with five private variables: [code] My main form is divided into a number of different sub procedures. In one of them, I used a streamreader to take the first name, last name, and phone numbers of a list of records in a text file called PersonalInfo.txt. It seems to work just fine. [code] I have another, separate sub procedure in which I read a different text file containing the "averages" for the students. The first average from Averages.txt belongs with the first student in PersonalInfo.txt. The second average goes with the second student.. How do I add the student average information to the properties of the student records created in the previous sub procedure? [code] I realize why this wouldn't work, but I can't figure out how I could use my counter to reference a specific student.

I want to include an average in a column where the average ignores zero values in a report cell where the column may have
17
19
0
[code].....
I want 16, not 11 so (17 + 19 + 12 + 13 + 19) / 5 not (17 + 19 + 0 + 0 + 12 + 13 + 19) / 7 Something like this if it would work.
=SUM(Fields!fieldname.Value) / Count(iif(Fields!count_cycle_per_hour.Value >= 0,Fields!fieldname.Value,0))
Essentially just average everything in the column NOT a zero?

I'm working on a function to return a exponential average and there are a lot of examples of exponential moving averages but they all start with a moving average that is just the mean as a lead in to calculating the continuing moving average. I needed just a exponential average of a value set. After Googling my Bing off I still haven't seen anything so here is my attempt at a basic exponential average. Is this correct? Are there any errors? I have seen some text about adding a smoothing value to change the curve of the exponential average but not how that would be implemented.

I'm in a computer science class, and we are writing simple programs using Visual Basic 2008. I am really inept when it comes to this, as I have never done it before. I need to write a program that: "Asks the user for 5 numbers and computes the average. It then displays the average with an appropriate message before the average."
I have been really close with this, but I can't get the numbers to add up, then divide by 5, and display a pop up message.

This exercise says :"Write a program that inputs one number consisting of five digits from the user, separates the number into its individual digits and prints the digits separated from one another by three spaces each. For example, if the user types the number 42339, the program should print
4 2 3 3 9 Use the command window for input and output. [Hint: This exercise is possible with the techniques discussed in this chapter. You will need to use both division and modulous operations go "pick off" each digit.]"
Here is what I have learned in Chapter 3:
�If/Then Statements
�Console.Write()
�Console.WriteLine()
[Code]....
This exercise I have yet to start, and don't think I will be able to do much, because I have no clue how to "Pick off" the numbers using division and modulous operators. I know what the mod operator does, but I do not know how to use it and division to do what this exercise is asking me to do.

A parking garage charges a $2 min. fee to park for up to three hours.The garage charges an additional 50 cent per hour for each hour or part thereof in excess of three hours. The max charge for any given 24-hour period is $10. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and displays the parking charges for each customer who parkes a car in this garage yesterday. You should enter in a TextBox the hours parked for each customer. The program should display the charge for the current customer. THe program should ise the method CalculateCharges to determine the charge for each customer. Ise the techniques described in the chapter to read Double value fro a TextBox. [ You may need to use methods Convert.ToDouble and Convert.ToDecimal when doing calculations with the number of hours and charges]
Public Class ParkingGarageFeeCalculatorForm
Private Sub calculateButton_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles calculateButton.Click
Dim hoursParked As Double = Convert.ToDouble(hoursParkedTextBox.Text)

I've been working for several days on a GUI where a lot of individual data elements need to be displayed side-by-side and wrap to the next line when they overflow; the goal is to not have to explicitly design an individual 'row' element with a set number of elements for this purpose. The FlowLayoutPanel seems great, except...
I need to be able to determine how many elements are on each line (dividing the width of the control by a predetermined value indicating width of child controls does not work); I need to be able to determine how many elements will be on each line (I may need to put 4 elements on line 1, then auto-wrap, then 8 elements on line 2, then auto-wrap, then as many elements as can fit on line 3 before autowrap, then 16 elements on line 4, etc); and finally I'd really like to put a 'line header' at the left margin and a 'line footer' at the right margin, where for example the line header contains a line number and the line footer contains the number of elements on that line.

I have a form with 10 math questions. Beside each question there will appear a check mark if it is right and a X if its wrong. I also have a label that will display a score in percentage. If 2 are right then it will display 20%. If they are all right then it displays 100%. My problem is ...how can I code the event. I thought of case select, but that would mean 100 cases to make it work.( If check1 and check2 are visible then display 20%, but if its check1 and check 7? Thats alot) What I want ot know if there is an easier or shoter way to ontain the same result. I am working with Visual Basic 2008.
