How To Display Fibonacci Results

Mar 2, 2009

I can get the results if I plug a number in for i, but I get them as a string for some reason.

'display Fibonacci results
Dim fib(10) As Integer
Dim i As Integer
Dim fibn As String

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

Display Fibonacci Sequence In ListView

Oct 19, 2009

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

Fibonacci Numbers And The Golden Ratio

Oct 15, 2011

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.

Fibonacci Numbers Loop And Output To Multiple Labels?

Mar 29, 2011

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

Conversion From String "Fibonacci Demo" To Type 'Integer' Is Not Valid?

Jan 16, 2011

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"

Developing .net Programs To Run On The GPU Instead Of The CPU

Jul 10, 2011

I am making a 2.5D rendering engine. I assume (with the knowledge that I've gotten from reading online) that doing the rendering work using the GPU will be faster than using the CPU.

Is this possible with .net? If so, is this a correct situation to utilize the GPU?

I'm also using VB.net, however all .net examples will apply.

C# - Developing ASP.NET Web Site For Different Languages

Oct 7, 2011

I'm building a website which will have a Spanish and Italian version.

In the past, when building a site which must be available in different languages, I've created a SQL Table like follows:

dbo.News
--------
ID int
EnglishTitle nvarchar(200)
SpanishTitle nvarchar(200)

However, I've found this really time consuming (especially if the client later asks for another language option as a second phase).

What is the best practice for doing something like this, allowing scope for extra languages?
