Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?
Aug 16, 2009So 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.

Add Every Combination Of List Of Numbers
Nov 1, 2010VS2010
VB
I would like to be able to add every combination of a list of numbers to determine which combinations equal a specific result.
Simple Example:
List: 2, 4, 6
Result: 10
How many and which combinations of numbers result in the number 10? The correct anwser is only one which is 4 + 6 = 10. The example is simple but the actual list may contain as many as 10 - 15 decimal numbers.
I have thought of the following as a possible way of checking each combination by using binary:
- There are 3 total number so the possible combinations would be:
123 - Three numbers
000 - Add no numbers
001 - Add the last number
[Code].....
However, I don't know how to actually match up the bitwise bits to the numbers in the array to actually add. Example:
101 - I should check if 2 + 6 != 10 per the example above so this wouldn't satisfy the result... does this make sense? The answer would be 4 + 6 = 10.
how to check and add all combinations from a list of numbers to determine if the result is a specific number?

Store Two Related Numbers In A List?
Sep 21, 2010Is it possible to store two related numbers in a list and then check them if the are exist in the list?ere is an example of what I did to achieve the above:
Dim CounterConnections, FromN, ToN As Integer
Dim ConnectionsList As New List(Of Integer)
Dim Myrandom As New Random
[code]....
The above code generate two random numbers and store the in a list. I am adding the two numbers to be one so that I can check if they exist in the list.e.g. if the FromN = 7 and ToN = 11 then the list will consist of :
711 and 117
a list to store 11 7 and 7 11 which is capable to be checked later if some some numbers are exists.

Vb6 Migration - List The Used File-numbers In VB 3.5?
Nov 23, 2011how to enumerate the used file-numbers [as in FileOpen(filenum, ...)] in Visual Basic .NET 3.5 (VS2008)?
The situation is: I'm doing "a quick port" (just to bring it up a supported architecture) of an old VB6 WinForms application (it's "just a tool" really, not a full-on app) to VB.NET using Visual Studio 2008's automatic translator, over the .NET 3.5 framework. The existing code stores "records" in parallel arrays, the index of which is the output-file-number, and output-files are opened and closed "ad hoc"... so I can't "just" use FreeFile (I could, but it'd basically be a rewrite, which we won't get paid for).
After translating I've got an "invalid filename or number" error upon FileOpen'ing filenum=350 for Ouput... I know the filename is valid, and doesn't already exist. I tried (just for debugging) setting filenum=FreeFile and that worked (i.e. the file was opened)... so I figure that filenum=350 is already open, but how to tell BY WHAT? A listing of the used filenums -> names would give a huge leg-up.I suspect this just isn't possible, but I've got to ask anyway, because it was save ever-so-much time, effort, and thought if it is possible, so here we are.
VS 2008 Generate Numbers In List Box?
Dec 8, 2010Create a GeneratedNumber application that stores in an array with indexes 1 through 100 numbers generated by the index values when Generate is clicked. Generate the number to be stored at each index by summing the index and it's individual digits. For example, 25 should be stored at index 17 because 17+ 1+ 7 = 17 and 4 should be stored at index 2 because 2+ 0 + 2.
Your program should use a FillArray() procedure to generate the nuymbers and DisplayArray() procedure that displays each index and its element in the list box.

Message Box To Show The List Of Numbers Entered
Dec 15, 2007Im trying to do a lab that will obtain 10 numbers from the user using an InputBox() function, store them internally in a one-dimensional array, and then compute the average of the numbers and sort them in reverse numerical order. The program should control that 10 numbers (no more, no less) are entered, and that the numbers are fully validated as integers.
If the user enters non-numeric data, then an appropriate error message should be shown, and that number should be allowed to be re-entered as a valid number. Then all the numbers should be shown as a list in a 'message box'. So far I can get everything but the message box to show the list of numbers entered.

I was wondering if the simplest way to do this is just by putting: ArrayA = ArrayA += 1 or what the simplest way to do this is.

Create A Program To List A Large Group Of Numbers?
Feb 7, 2011I 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

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?
