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?

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

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...."

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]
View 2 RepliesEDIT: Solved (see comments) I have a For loop inside a sub, and right below it I have a MessageBox function. Everything compiles correctly, however for some reason, if the loop executes and exits successfully, anything outside and below the For doesn't get executed.

it displays only 10 items in the ListBox afterwards. I've searched everywhere, but I did not find anything related to such an issue. I'm kinda puzzled, anyone got a clue of what's going on? EDIT: Forgot to specify, the sub is actually a TextBox.TextChanged event
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

We're using the Autocomplete functionality for some textboxes. We populate the AutoCompleteCustomSource with data from a database query using a datareader loop. The data in the query is sorted by 'recently used', the most recently used entries are at the top.
Let's say the sequence op the AutoCompleteCustomSource is
'AM1900'
'AF2000'
'AD1950'
After typing an 'A' in the textbox, I would expect the Suggested (or Appended) value to be 'AM1900'. The suggested value however is always the first item from an alphabetically sorted
AutoCompleteCustomSource list (i.e. 'AD1950')
I am trying to write a code for Fibonacci series in VB, but some of the values in my series are incorrect.Below is what I have so far.

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
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.

So my teacher gave us this assignment that I'm having trouble understanding why she wants us to write outside of the button Private Sub.1. Write the code for the Calculate Total and Grand Total button a. Declare a variable to accumulate the individual totals outside the sub procedures b. Calculate the total by multiplying the selected number of atendees by the selected cost, and display this total in the label next to Total c. Calculate the grand total by adding the total calculated in step 3.b to the grand total variable. Display the grand total next to Grand Total I'm don't understand why she says 1a. I feel like you can just write all the variables in the same Sub on the calculate button.

View 1 RepliesSo 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.

Have to develop an application that will let me choose between cell phone plans, individual and family plans i have the forms and all choices done,. new forms open and old ones hide to keep it clean. i think i got all the variables declared, and got no debugging errors, but when i select the options, it always gives me the following:
1. adds one more phone than selected
2. only shows phone subtotal, tax and total
3. prices for options and monthly fees never show
Here is my code for all 3 forms

I am trying to unit test for data being input into a textbox (txtPrice). If it is not numeric, it throws a messagebox stating that the input must be numeric. However, when I unit test, I can't figure out why my test fires the message box twice.THis is my (simple) unit test:
Public Sub txtBoxes_LeaveTest()
Dim target As frmEstimate_Accessor = New frmEstimate_Accessor ' TODO: Initialize to an appropriate value
Dim sender As Object = Nothing ' TODO: Initialize to an appropriate value[code].....
My understanding is that for unit testing, you declare the sender, and (in this case) set the sender to some value that will trip the message box. 112L should do this on the leave event. I then write my expected, which in this case is 112L, fire the event, and then get the actual out of the text box. I then Assert.AreEqual to ensure the expected and actual are the same.
Working through trace tables and wanted to check to see if my results where correct, I have designed the following code to check each stage of the loop, but the code keeps throwing up an error about casting when i try to run it. I can see when the error comes back that the writeline is holding info but what have i done wrong.

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 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 was given an assignment to "write a program to print only even numbers between 6 and 16 using events", but I don't even know where to begin. The main thing I am having difficulty with understanding in this assignment is how I am supposed to specify that it only print even numbers in the given range of numbers.
Am I going to have to do a Mod2 code for each individual number and have it exclude any with the result of 1? Or is there another piece of code specifically designed for such an occassion? Perhaps there is some type of equation I can have the program read in terms of a variable, which holds the values of 6, 8, 10, 12, 14, and 16? I am just genuinely confused on how this is supposed to be programmed.
I have 202 .html files and at the beginning of each file, I need to add a chunk of php code. I could make this myself, but to be honest, it would take me forever and I might as well just manually edit them lol. All the .html files are in one folder.[code] one other thing that would be VERY cool, is if it could add the files that are not edited to a listbox or an outputted text file.
View 12 RepliesI am learning inheritance in VB.Net. A homework assignment asks me to write a base class with a name (String) property and a ToString method that displays the name. It also asks me to create some child classes of the base class and also implement a ToString method in those child classes. Is it possible for me to call the ToString method from both the child and base class?
[Code]...
Again, I am wondering if there is a way to call the ToString() method within the child class and then base class to generate output something like: "Hello VB.Net This is the name"
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.
