Displaying All Prime Numbers In ListBox

Mar 13, 2010

I am suppose to write a program using if statements and loops: Create an application that reads an integer number from the user and then displays in the List Box all prime numbers (for this project we are going to violate "positive" rule and make our prime numbers be negative as well) between user's number and zero 5 numbers in one row. The application also displays how many prime numbers there are between user's number and zero, and the total sum of all these prime numbers.

398 Million Prime Numbers And Growing?

Aug 17, 2011

[URL]

Each set of ( 1 million ) prime numbers is in a ZIP file just click on say 1st Million

on the left to download a list as a ZIP file.

Here is a similar page which is a lot easier on the eyes:>>

[URL]

These are of course great to use in any security application or as part of any password.

However with the list so readily available on the internet is it such a good idea to use a prime number as part of a password? Food for thought perhaps? ....

I guess it depends on how long it is too. :-)

You could try to remember one that is close to an important date or other number that you know maybe?

If you are more paranoid use more than one prime number in a password with other characters ( UPPER and lower case letters etc ).

Just out of curosity, what's wrong with the following line. I'm trying to create a range of integers (3,4,5...,50) and then filtering out only those numbers which are not divisible by any integer less than themselves (bruteforce way of finding primes).

Enumerable.Range(3, 50).Where(Function(x) Not Enumerable.Range(2, x - 1).Any(Function(y) x Mod y = 0))

Determine Prime Numbers - Calculate Button?

Mar 17, 2011

I am creating an application that takes two numbers (lower and upper) and determines the prime numbers

Public Class primeNumber
Private Sub calculatePrimesButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculatePrimesButton.Click
'declare variables
Dim number As Long
[Code] .....

Once I hit the calculate button nothing comes up. I've tried adding the first code inside the function with the remaining code but no result. Now I'm putting the first code in with the calculate prime button. I am guessing there's a sqrt method that needs to be applied but I am not sure if it should be part of the function or the main?

Function To Check For Prime Numbers Within A Range?

Dec 4, 2010

I have two user inputs (as textboxes) for two numbers I'm looking to check for all the prime numbers with the range of those two numbers and display them within a multiline textbox, however my code returns nothing but zeros, and I have seen easier ways to do it without functions but I am curious as to how to go about calculating primes within the function.[code]...

Make A Program For Finding Prime Numbers?

Dec 21, 2011

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!

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Calling A Function To Display A Range Of Prime Numbers

Dec 5, 2010

I am trying to create a form that allows users to input two numbers a high bound and a low bound then when you click the calculate button it determines all the primes within the range and displays those numbers within a multi-line text box. It seems I have everything working except how to display the prime numbers, the result from the following code displays nothing but zeros so I suspect that the range is not being saved somehow? I have asked this on other sites and people just give me completely different code or their own, can anyone help me with this specific code without changing the underlying code, I have a feeling I might be missing a variable or I am calling the function incorrectly.[code]

Displaying 8-bit Numbers From A Microcontroller In Real Time If Possible?

Apr 26, 2010

I've already wrote a simple program for connecting to a serial port that can send data to the microcontroller, do some basic arithmatic and transmit it back to my Form. This was just to see if I could set up the conection.I have a PIC Microcontroller giving an 8-bit number thats is taken from an external sensor device.What I want to do now is to present this data from the microcontroller in a textbox as a number either in real time (as the sensor output changes) or if not possible, on request (using a button).

Show A Textbox Displaying Numbers With A Control?

Jun 20, 2011

I have three Buttons labled "Single" "Double" and "Triple" and four textboxes, one for each button and one to display the results. Here is how it works. Each time I click on one of the buttons, it increments itself by that number...for example if I click on Button with the word "Triple" on it I will get the result '3' in the adjoining textbox. If I click it again the number will change to '6'. This holds true for all the buttons. I have this part of the program working well. there a way to have the addition of all these numbers appear in the fourth textbox WITHOUT having to use another button. In other words I want the fourth textbox to constantly update as I'm pushing buttons.

WHILE LOOP Displaying Wrong Result When Counter Is Incremented?

Feb 23, 2011

Im writing a program and its pulling data from a .MDB to put in a .DAT file.

Here is my while loop:

vb
database_connection()
sql = "SELECT * FROM tlalist"

[Code].....

In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.

Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.

How To Add Numbers With A For Next Loop

Adding Numbers To Text (for-next Loop)?

Jul 11, 2009

I have a text file (*.txt) with a name in each line, like this:

Joe
Dane
Lisa
Kelly

Now I want each name added with a number from 1 to 99.

Like this:

Joe0
Joe1
Joe2

[code]....

I have folowing code:

For n As Integer = 0 To (numbernames) - 1
strContents = objReader.ReadLine()
For i As Integer = 0 To 100 - 1

[code]....

With this code all happens ok and a new text file is created with the desired name-list with added numbers.The only problem is that the last name doesn't get a number added from 0 till 99 but for example 0 till 17.
