Forms :: Break Down Numbers Program?
Sep 8, 2009
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

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.

So I have some vb.net code, and I have a nested For loop inside a For loop, and then I have EXIT FOR statement, will it break out of one loop, or the whole chain?

I just got Windows 7, so I re-installed VB 2008 Express and have been met with some weird issues. One of which is when my program is running it used to break on a line where an error was occurring and tell what it was and let me fix it and continue. So I can see the error in the Immediate window but why is it not breaking on the line? It just continues loading the program. Is there a setting I'm missing?

I'm using VB 2010 and need to multiply 2 user input numbers in forms, so basically: TextBox5 = TextBox2 * TextBox3 That obviously didn't work but it shows what I want it to do.

-new Dell laptop without a Break key.
-VB6 and VS2008 IDEs use Ctrl+Break to pause execution for debugging.
-I need a way to map another key combination to trigger a Ctrl+Break
My setup may make this easier or harder but to be clear I am running Kubuntu 9.10 (latest stable) and WinXP in a VirtualBox VM. Obviously all VB6/VS2008 dev is taking place in the virtual machine.So maybe it's possible to have the linux host send through Ctrl+Break based on a key mapping, or maybe it's possible to remap directly in WinXP. I'd settle for any solution as atm I need to use the XP On-Screen keyboard to send a Ctrl+Break.

I'm working on a Windows forms app that will average a set of numbers, the only catch is that there are 10 textboxes(4 in the example for times sake), and not all of the textboxes could be filled with a number...I know that if i had a given set of numbers:
Dim a, b, c, d As Integer
a = t1.Text
b = t2.Text
c = t3.Text

i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?
Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.
What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.

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 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'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!
