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.
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.

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 [Code] .....
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?

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 Try
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 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]
I'm a college student who has a basic-intermediate knowledge in VB.NET, C++, C# and Java. I'm planning to develop an application similar to Microsoft Windows (Windows and Sharing Center ).
The application will able to perform Wireless Detection: scanning the area for available wireless network and presenting them to the user of the software, and then user can decide to which network he/she wants to connect.
I am trying to develop a chat application using Visual Basic 2008. I have referred some articles on the internet like [URL]...rogramming.htm and got the concept of connecting and sending data. But when it comes to real world chat applications, there is user authentication and all that. So I was wondering if it is possible to make my own Windows Live Messenger or Yahoo Messenger!!. I searched web for such a sample or source code, but could not find any. Has anyone here created such an application??
i developed a very simple vb.net application and i need a way for every user to verify that they have paid for it. i would like the simplest method possible. it will be an off-line registration. I am actually looking for a way that I can program this easily myself, and am not interested in third part solutions.
I have been assigned a task of exploring unit testing using tools available in the market.My question is how do i write an API that would help in writing unit test cases.Example i can use nunit to write something like this to check whether file exists in the given location.

I am looking for best practice for developing new application. Our company has developing VB6 application for customers about 10 years. This application has mostly math calculations and works with MS Access DB. Now we are looking for method how we can develop WEB application with ability to client to download application for local work. Some of customers does not use internet at all from security reasons. So the WEB solution only not enough for US. I understand that WEB and Win.Forms have different user interface, so I am looking for best practice to create engine for both platforms(Web and Forms) . The main task for us is minimization of maintain and designing. Is there any technologies can be used in web and desktop app at the same time(like dll). I do not know how to make next step in order to estimate this project.
I am responsible for rewriting an internal tool for my company. I am currently reworking the most time consuming step to run faster which should give me time to re-think the design of the application for a full rewrite as the interstitial version will meet the current needs. I really want to take this opportunity to implement this code using BDD/TDD but I am new to this method of programming in general and especially within the context of .NET. Are there BDD/TDD tools available for .NET? What resources should I look at?
I am new to Visual 2010 and cannot seem to find any information about using Charts.I have an array, call it PressureOutputs(1000), which I wish to plot against a second array,e(1000).Can anyone please explain how I would add these two arrays to create a series on an x-y scatter graph (which is already present on the Windows Form Application), or point me to a source of information about how to do this?
If used the following code to create three line series and three point series consists of only one point each.[code]I need to check if X value and Y value of the two series matches.How can I find the X and Y value of a point within a line between two points like the ones in the picture?
I want to know how a row from a datagridview can be put into a series of textboxes say 1,2,3.I have connected the datagridview to my ms access db, with three fields. I have three text boxes too. i just want to know how to get the row from datagridview to be moved to the three textboxes accordingly.
i'm new to visual basic and i'm trying to expand my programming knowledge by creating random projects that include personal advantages. Right now I am trying to create a program that prescribes a series of commands necessary for the execution of game emulators with the touch of a couple buttons. ive created a gui of sorts ... i just don't know to make it function.
