Create A Program To List A Large Group Of Numbers?
Feb 7, 2011
I am currently trying to create a program to list a large group of numbers for me. My final goal is to have every 2, 3, 4, ..., and 9 digit number containing only "1" "2" and "3". I thought I would go about this by using the following VB.NET program and then copying it into a text editor, and using find & replace to eliminate all other numbers.
Public Class Form1
Dim Start As Integer = 333333333
Dim Counter As Integer = 333333333
[Code].....
it fails due to the massive amount of processing that needs to take place. However, adding the intervals requires a great deal of time for each number to be displayed without any crashes.
Is there some way (in VB.NEt or another language) to get the number list I want in a short (an hour or less) amount of time?

I would like to create a sub menu that list part numbers that are gathered from a xml file. I am having trouble with creating the sub routines for the part numbers menus because it can change.
Private Sub mnuP1Layers_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim BFFile as string
My.Computer.FileSystem.MoveFile(BFFile, "C:ExchangePrintedBFFile")

I want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long
After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.
The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single

Basically this is my problem, showing the results of a string. I am making a program for a customer and he wants to be able to extract a string or set of emails from a large group of text. In this case he wants to be able to copy a webpage and extract all the emails out of the webpage. The problem i am having is showing the results of the List(of string) Function. So far, I can copy the page, paste the content to a textbox and then i have a function that is supposed to filter out the emails and paste or Show them in a list box.
I dont know why but no matter what I do I always get this error:
Error1Value of type 'System.Collections.Generic.List(Of String)' cannot be converted to 'String'.
This happens when I try to output the return results to a textbox or list box.
Here is the code for the whole program:
Entire Program Code:
Imports System.Text.RegularExpressions
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
I have tried almost everything I could do, I am relatively new to string functions so that is my main problem.

I'm fiddling around with trying to make a sort of map/world. I'm using 16 x 16 pictureboxes named PictureBox1, PictureBox2, etcThe issue is that when I put the images into all the pictureboxes, I have to have a line for each picturebox (so say I have 100 boxes, I have 100 lines).The only difference in each line is the picturebox number, the rest is identical. I'm basically telling it to set that picturebox's image based on the number that a variable I've created has stored.I've got a game idea, and I'm just trying to figure out how to do the map. I want it to work like the old school RPG games like Dragon Warrior, or the more recent Dwarf Fortress. I'm still not sure if I want to use graphics or letters. At this point, I'm just trying to figure out how I can create the main screen where the user moves around. This is what I've come up with, as it works with what I know. I'm pretty new to this, although I've messed around with VB6 a lot.
Dim tile(30) As Integer
Dim tilelocation(3) As String
Dim x As Integer

I have to create program that adds the whole numbers from 1 to 1000 and displays the sum in the label. Create a variation of this program that allows the user to specify any starting whole number and any ending whole number (10,000 or lower) and then adds all the whole numbers in that range. Allow for the possibility that a user may start with a high number and end with a low number. Format the label so that commas are displayed and there are no decimal places showing. I need help with the codes.

Any simple way to add commas to large numbers (example: instead of "123456789" as my text converted {and loaded into a text box} output of a calculation, I want to see "123,456,789")?

This piece of C# code does not produce any overflow exception.wordsize is a constant equal to 32.the x and y can be very big at the computation time. So big that long or decimal even cant hold. But C# handles the problem even the value of the variables exceeds its limits.The computation gives thr right result.(I dont know how it does it)

I want a method of dealing with very, very, very big numbers (potentially a million digits). It is very cumbersome to deal with very big numbers in VB, would another language perhaps be better for that?

i am creating a maths program that works out five number summarys of a range of data. i am having trouble working out the smallest number in a group of numbers. i have used a bunch of if then statements to work out the maximum and i figured that by exchanging a few variables and swapping greater than signs for less than i could use the same code to work out the minimum, but all i get is zero, no matter what i input into my textboxes. below is the code i have used to work out the maximum number
If CheckBox1.Checked = True And CheckBox6.Checked = True Then
max = 0
min = 1000

How is it possible to deal with incredibly long (large) numbers in vb.net?I am working on Problem 25 in Project Euler, and my program cannot handle these computations.Is there a data type that can handle thousands of digits?

For example, to calculate this:(22 ^ 29) Mod 57Supposedly there is a way to get around overflows and do these calculations, but I can't find much online. Now, the person who said this was doing VBA in Excel and said that there was about 4 lines of code which could handle the overflow so it wouldn't happen.

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.

Say for instance, I gave you the numbers
1, 2, 3, 4, 4, 6, 9, 1, 3, 4, 5, 5, 2, 4, 7, 9, 1, 5, 3, 6, 6, 8, 1, 1, 4, 7, 7, 8, 2, 4, 2, 1, 9, 1, 0, 1, 6, 3, 2, 1, 8, 8, 9, 8, 1, 5, 3, 2, 3, 4, 7, 9, 0, 1, 2, 4, 7, 4, 3, 9, 7, 2, 0, 1, 6, 3, 8, 1, 2, 4
What number appears more than any other number?This is very important to me, ...I need to find the MODE, of those group of numbers, ...the way that I did it before, I would make 10 TextBoxes, and have another text box to enter the number, and when the number gets entered it would increment the value of which ever textbox the number was in the main textbox, so if I entered a 1 into the main textbox, then the zero in textbox (1), would be incremented to 1, and if another 1 was enered and the button was clicked, the 1 in the Textbox for 1, would be incremented to 2, because 1 has a popularity of 2 now and has apeared 2 times..
Here's some code, to show what I've come up with by myself.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ONE.Text = ONE.Text + 1
End If

I'm just learning VB with the 2008 express edition.I'm trying to create a program that uses 3 list boxes.The first contains a list of products.After a search is preformed the second list box displays the products found.This is pretty simple, basic array stuff.My problem is moving items from the second list box into a third list box to purchase the product.I think I need to change the index numbers of the stuff I move into list box 3 because when I preform calculations with the stuff in list box 3, it seems to answer like its using the index numbers in list box1.So, how do you change the index numbers when you change list boxes?

I'm using Visual Studio 2010 Express Edition - Visual Basic.I'm very new to VB but I would like to create a program / splash screen that displays a list of files (Word, Excel, Project) that are located on a CD. I'm not sure how to start other than starting out creating a new project.
Here is how I would like the program to work. The user inserts a CD-rom (containing the program and a folder with all the files) the program automatically starts up when the CD is inserted and it displays a list of all the files on the CD. The user can click any of the files to start the program that created it. Example, if we have an Excel file called "Work Schedule", the user could click it and it would open in Excel.
After I've created the project and have a form, I'm not sure what tools I need to use to display the list of files.I'm not sure how I set up the connection (path) between the program and the folder containing all files, especially as they will all eventually be located on the same CD.
