So I am trying to solve this program using the algorithm given, and I get no error messages but everytime I execute the program it just crashes. Any idea what I am doing wrong?\The user wants a program that will return a set of perfect numbers based on the value that is given. If the user types in 3, the program will return 3 perfect numbers
So this is the code I have so far...
dim perfectnumber as integer = 2
dim divisorRunningSum As Integer = 2
I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
Drawing a 3-D border should be easy enough, right? Nope. Does anyone know how to draw a border that looks exactly like TextBox's? Right now, I'm just drawing black lines at the top + left and white at the bottom + right but the bevel isn't nice and when the background color is white, the bottom + right don't show up.
Almost 2 months i try to find perfect solution for my project. I making one multi-user chat application with SERVER and CLIENT application. I read a lot of material about socket communication and try a million of examples all around, some in C# some in VB.net, but I can't find solution.Problem that every example and my try have is when 10-20 user chatting really fast, server reacting slow or whatever is, but final product is that two or many message show in one LINE. For example if i send string "test1" and an my friend, let's call him FRIEND1, send "test2" almost in same time, server sending it to all connected clients like this:stefanACM:test1FRIEND1:test2.I try to implement in my application "Asynchronous TcpListener & TcpClient" from jmcilhinney, but have same problem...
So, can anybody help me with this.I just need one server application that will recive connection, save IP and nick of connected user, and send every message that client sent to all connected users (of course without problem that I mention on beginning of post). On end, that when client disconnect just to close connection.From Client side I need just connect part, send and receive messages.
So in one line, I think I need BASIC EXAMPLE OF PERFECT MULTI USER CHAT CLIENT AND SERVER, without any hiden bug.If someone decide to help me with code,
What wrong with my databinding? How to correct the perfect binding with combobox and texbox.. When I select Projectname the other are changing except the email... Why the email is not changing?
Code: commemails = New OleDbCommand daemails = New OleDbDataAdapter dsemails = New DataSet dtemails = New DataTable myconn = New OleDbConnection(("Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=") + My.Application.Info.DirectoryPath & "SMRPsource.mdb") [Code] .....
I am using this code to bring data in combobox but u_id is the premiry key n not full name then on selection how can i bring the perfect result?[code]...
Includes alpha blending, pathfinding, grid rendering, and lots of other algorithms that make basic game programing in VB 2010 a lot simpler. Copy the code in the attached text document into a blank class. Then add it to your project. Initialize as you would any other class...
"Dim aGameGridOrWhatever as New DynamicBitmap"Let me know if anyone finds any bugs in the PathFinding algorithm. I finished it tonight. I'll post some examples of how to do stuff to this thread soon.
I am currently writing a program that when a user enters a number such as 1267 and clicks a button the number will then be broken down by its ones place, tens place, and so on. So it would show up as One place is: 7, Tens place is: 6, and so on.Well I need a little help trying to figure out what code I would write to test or separate each single integer. So far I have only been able to separate the ones place using:
Dim ones As Integer = Microsoft.VisualBasic.Right(TextBox1.Text, 1) 'display each value in the corresponding place Label11.Text = ones
of course this code wouldnt work for the rest of the digits entered.If a user were to enter a bigger number lets say:
12345
then i would need to display
thousands place is: 12 hundreds place is: 3 and so on and so on
This displays as many numbers as i want but will also display a single letter.

I have a program that throws out a string of six numbers from 1 to 37, what I need to do is check the the string for for a format you could say.I need to make sure the set of six numbers doesn't contain 4 or more numbers of the same numbers from the same set of ten(s).
Like this:I can't have: 1-3-6-7-8-12 Or 12-14-16-18-20-21 Or 21-23-26-28-30-31 Or 30-32-34-36-20-22
I can have : 1-3-6-12-17-23 ////////////: 12-14-16-20-21-22 ////////////: 20-1-13-23-26-30 ////////////: 1-37-22-33-30-9
First off, I'm not sure if this is the right forum, please move it if it isn't. I am only just beginning with visual basic and I am trying to write a basic program to calculate the prime numbers from 1 to 100. This is what I have so far:
So I have been assigned to create a program that finds prime numbers. And then for the final part of the program I need to have the computer find the millionth prime.
I'm supposed to design this program in ConsoleApplication about Phone Numbers:
You are writing a program and you need to store telephone numbers. You'd like to be user-friendly, and let the users enter their telephone number in whatever format they like with parentheses and dashes, so long as they enter 10 digits. Assume that they won't enter any other characters. The user will only enter ( ) - spaces and numbers.So, these would all be valid inputs
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
how to make a program that makes all the possible characters and numbers (A-Z & a-z & 0-9) from 5-20 characters, and put them in a list or something?
Someone may think this is bruteforce hacking, but I don't see why I should do that? If I want to find a password on 13 characters, it would be: 62^13 = 200028539268669788905472 possibilities... in other words... it would take forever!
I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are. I'm working on making it a program that will calculate the Hardy-Weinberg equilibrium for my Anthro Class. I'm just doing this for practice for my VB.Net Class. But i will move onto that at a later time. I just want to finish this first.
So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.
I am making the tough transition from VBA to VB and would be pleased to hear from a VB expert. I am trying to make a program to grab numbers from the screen so that I can log them to a text file. The numbers are part of a flash animation which is regularly updating the number I want to capture and as there is no API i am grabbing the region where the number is displayed into a bitmap and then want to recognise the number with OCR. The code below grabs the screen region ok.
I am a newbie programmer and I need a way to generate random numbers for a program I am working on. It just needs to be something simple that generates a number and allows me to assign it to a variable. I would like it to be something small say 1-10 would be good and an explanation of the syntax would be helpful
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 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.
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.
Basically what I am making is a form with just one button and 2 text boxes. The purpose of it is that when I click the button 2 random PRIME numbers between 100-999 will show up in the boxes. With my code I have now, the numbers that show up in the boxes aren't always Prime.
My current Code is....... Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Randomize() Dim p, q, i, j As Integer [Code] .....
