Finding The Average Of A Set Of Numbers In A Listbox In VB?
Jun 20, 2012
I enter numbers and Names into a text box and click 'add to list'. THe names go into a seperate listbox to the numbers.I then press 'show me the list' and i get to view my numbers and names listed in the two listboxs. I also have a button which averages the numbers in the numbers list box. But i dont know how to get it to work I will divide by the number of items in the list box.note: The average will be displayed in a label called: lblavg

I am supposed to create a program that inputs 3 numbers, takes the two largest and outputs an average of those two numbers using simple ifelse statements and logical operators only. I can't seem to get it. I've messed around for a few hours now and nothing seems to be working.
Here's what I have:
Private Sub btnCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalc.Click
Dim score1 As Double

Im trying to write a program that will do:
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."
Im using visual studio 2008 and it has to be written in VB

I'm working on a simple miles-per-gallon calculator.
Module Module1
Sub Main()
Dim count As Integer = 0
[code]....
This compiles and works for 1 iteration, after many trials and tribulations . What I need to do is make it run for a user-specified number of iterations (the tankfuls variable) and store those separate results in separate locations in the arrays, then average all of those values at the end (find the overall average MPG).

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.

OK, so I've been given an assignment due for Monday, which was to create a console program which allows the user to enter an unknown quantity of numbers, then have the Mean, Median and Mode averages displayed of said group of numbers.
So far I've managed to get the Mean and Median to work, for both odd and even quantities of variables. I am however stuck on getting it to calculate the modal average! I don't really know how to approach this, would a structure with two fields, variable and quantity of variable, work?
Below is the code, I haven't made it display discrete of continuous data yet, I'm leaving that for the end.
Module Module1
Sub Main()
Start:
'Declare Variables

I imagine this is quite elementary for most of you, I unfortunately received no replies what-so-ever to my last thread...
PS: Why isn't there an option for UK in the two letter country codes?

I'm working on a Windows forms app that will average a set of numbers, the only catch is that there are 10 textboxes(4 in the example for times sake), and not all of the textboxes could be filled with a number...I know that if i had a given set of numbers:
Dim a, b, c, d As Integer
a = t1.Text
b = t2.Text
c = t3.Text

I am new to VB and need to make a program that does the following:Write a VB.Net program that allows users to enter a series of numbers(separated by a comma) in a text box called series. When the users clicks the command button called Average, the program extracts the number one by one from the series and calculates the average, and outputs the average onto a textbox called Result.I understand how to get it to do the average, but how can I make the program count the numbers that I input and then divided by the sum? Also, how would i get it started.

I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference

i am creating a maths program that works out five number summarys of a range of data. i am having trouble working out the smallest number in a group of numbers. i have used a bunch of if then statements to work out the maximum and i figured that by exchanging a few variables and swapping greater than signs for less than i could use the same code to work out the minimum, but all i get is zero, no matter what i input into my textboxes. below is the code i have used to work out the maximum number
If CheckBox1.Checked = True And CheckBox6.Checked = True Then
max = 0
min = 1000

I needed to make a program for finding prime numbers. The logic is that you have to put limits n & m and then LOOP and odd-integer P between n & m inclusive. I have a button to click on my form that displays 2 message boxes, one saying " enter upper limit" and the other say "enter lower limit". I need now to get the results of the odd prime numbers between the limits into a list box!

I have a program I'm working on (a chance game) that has 5 random numbers generated. I need to think of an expression to check to see if three of those numbers are equal. The random values are not an array, they are 5 separate variables. I have the code written to compare if there are two matching ones, but am having trouble thinking past that. [Code]

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?
