VB 2010 Fibonacci Using An Array?
May 21, 2011
The assignment is this: User inputs the number of fib numbers they would like displayed. The program takes this number and produces that amount of fib numbers using a function and an array. Function can not display the results, that has to be done in the button's click sub.
Now, I really thought I had this array stuff nailed, I have done the random lottery number program and all that... but I think somewhere along the time it has taken me to get this messed up code I have written, it has also confused me to no end. I started off just being confused about how to display all of the variables in the array, now I am just not sure what is going on. I have successfully written this program without the use of an array prior to this.
Option Explicit On
Option Strict On
Option Infer Off

I can get the results if I plug a number in for i, but I get them as a string for some reason.
Private Sub displayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles displayButton.Click
'display Fibonacci results
Dim fib(10) As Integer
Dim i As Integer
Dim fibn As String

I am supposed to design and develop a program to compute the first X integer numbers of the sequence, where the X value is entered in a numeric updown Control only using values 3-150. It is supposed to display the results in a listview control that has one column. I believe that I have the code correct but I am not sure how I am supposed to add items to the column in the ListView box. I have reviewed my text and there is information on creating the listview box and adding columns but it does not show an example on adding data to the column in the listview box. I can compile it with no errors but I can't debug it.
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Dim fib1 As Double = 0
Dim fib2 As Double = 1
Dim counter As Double
Dim result As Double
result = fib1 + fib2

So I need to write a program that will approximate PHI (the golden ratio) using Fibonacci Numbers. It has to be within a negative power of 10 (between -1 and -16) oh PHI. So for example, if I put -2 into the input, the approximation of PHI would have to be with 10^-2 of the number that we're using of 1.618033988749895. Also, we need to show how many Fibonacci terms that were used to get to that number and the difference that the number that we approximated is to PHI.

displaying the first 10 Fibonacci numbers. My code displays the following result: 1, 2, 3, 5, 8, 13, 21, 34, 55 and I need it to also display the first two Febonacci numbers (0 and 1). How would I do that?
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Have to write a program that would display the Fibonacci series with the condition that the inputted number from the user is also the number of Fibonacci numbers that would be displayed. And 0 is invalid.

Write a function to print the Fibonacci value at a given position in the series.you should write two versions of the function both of wich must be named Fibonacci(overload functions).the first version should be implemented using a for loop.the second version should be implemented using do until.

I have attached the form in initial state. What you don't see in the initial state is 10 hidden labels. I want the loop(which I am calling as a function??) to compute the numbers and display in the labels. Example, if I input 1 for the first term, 3 for the second term and 4 for the total terms, the first 4 labels should become visible and have in them one solution each:
1 - 1
2 - 3
3 - 4
4 - 7
Am I way off with what I want to do? Cannot use arrays, must be a loop.This is the compute button:
Private Sub BtnComp_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles BtnComp.Click

I am trying to get a better understanding of the uses of arrays in programing, and have been wondering why do programmers use an array when working with mathematical concept such as Fibonacci sequences? why are arrays so prevalent in coding now a days.

I'm trying to create a program which will calculate the Fibonacci Sequence which calculates the numbers correctly however, there are a few problems.
1. When using a Do While...Loop the program becomes non responsive.
2. Kind of dealing with the program becoming non responsive; I am unable to stop the process by forcing the sub to Exit.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Operation.Text = "Calculating...."

When I use the included code to position an InputBox over the start of a listbox named lb I get the following message: Conversion from string "Fibonacci Demo" to type 'Integer' is not valid.
The code works ok if I remove the L,T, parameters. If i replace L,T with 100,100, I get the same error message.
Dim MyValue, Msg, Title, DefaultVal As String
dim L as integer, T as integer
Msg = "Enter Value > 2 and < 45 to be evaluated"
Title = "Fibonacci Demo"
DefaultVal = "5"

I'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click

I am working on an assignment that will display the forst 10 fibonacci numbers in sequence. However when my results are displayed, the numbers are all stacked on top of each other like this: 011235813213455. I have tried to play with it but i can't seem to get my numbeers to space out or even maybe have a comma "," betweeen each number.[code]

Here is a code in my VB6 application.
Array(1,"P11","@P 100", "NEXT")
However, now I'm converting this program to VB.Net and I'm stuck at this point. Can't find Array(xxx,xxx,xxx) in VB.Net 2010. Is there any option or function for this?

I am trying to create the following program Store in a 1d array a set of 5 place names and in a 2d array the distances between the places. Ensure that the order of the places is the same in both arrays. When the names are places are input the distance between them is displayed. If they are not both in the table a suitable message is displayed
Dim town(1 To 5) As String
Dim Dist(1 To 5, 1 To 5) As Integer
Dim First As Integer

I think the best way forward is pass a parameter to the function findnumber.

Am learning arrays at the moment and I have the below piece of code that goes through drive C: and displays the files in in a list box.
I want to try and expand it to use array.sort so that it gets the files, puts them into an array, and then I can sort by filename or file size. I have been rattling my brain over this - as to how do I put the files into an array.
Private Sub btnclick_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnclick.Click
Call Clearlist()
