I have this code:
Module Module1
Dim x As Integer = 1
Dim y As Integer = 1
Dim arr(x, y) As String
Sub Main()

Receive Upper Bound And Lower Bound Of A Range

Sep 20, 2010

Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate

1) the numbers are integers
2) the lower bound is less than or equal to the upper bound
3) the number to generate is positive (i.e., > 0).

Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.

Read In Text File With Undefined Upper Bound?

Jul 21, 2010

Alright, so I've got my program and it works, but I have to pump out updates every once in a while. If I can get it so the code will let me have my text file with any number of lines for my array, then I can simply send out a text file and update done.So here's what my code does:

Define a record of arrays, two items, a unicode string (Japanese/Korean text) and then an English translation for the text.I read in the file, it's one item per line, unicode string and then the translation.I have it preset with a defined upper bound for my array, but if I just took out the define and leave the upper bound as limitless, then it would work if I just updated the text file. Problem is, I don't know how to do it with stream.reader (I think that's what it is) because I learned a different way in school. I want to do something like Do While Not EOF with this, and loop it reading lines from the file.

Would it work if I change the array to no upper bound and then simply use Do While Not EOF with stream reader?

Create A Random Number Generator That Iterates Through A Series Of Number Between An Upper And Lower Bound?

Jun 24, 2010

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

Multidimensional Array Of Classes?

Mar 17, 2010

I'm writing a game in visual basic 2008 and things are going fairly well with it for the most part.. well until today.. I can declare a 1 dimensional array of a class just fine but cannot for the life of me get the syntax right for a multidimensional array. I usually don't have many issues in writing in VB but this is the first large scale program I have ever written in VB2008 and the 1st large scale uses of classes in VB as well

Here is my code to better illustrate my problem here is the class..minus most of the properties Public Class Objectives private zone as Integer private TZone as integer Public Property TargetZone As Integer Get Return TZone End Get Set(ByVal value As Integer)

Multidimensional Array Within A Structure

Oct 23, 2009

I'm very new to VB.NET and I suppose this is a little big for a first project.I've done the same thing in other languages so I figured it wouldn't give me much trouble.I'm working on a map editor program for a 2D platformer game.The map will be an array of a structure which contains the width, height, and tile elements of each layer. the tile elements are stored in a 2D array within the structure.[code]That didn't give an exception but I'm not sure that it actually redimmed considering the second assignment command still crashed.

Sort A Multidimensional Array?

Sep 23, 2011

vb.net 2005.

I have profitMarginArray(29,3) <29 is actually a variable, but figured I'd put in a number for the example> and what I need is to retreive elements 0 and 3 sorted on 3 in some way shape or form. The biggest problem is element 3 isn't unique so there could be 5 that have the same value (56.34 for instance) so a sorted list is out.

The current array could look something like

Item1, .34, .75, 54.67
Item2, .32, .75, 57.33
Item3, .29, .5, 42

Sum Column In Multidimensional Array

Dec 12, 2010

* I posted this in VB forum at first by accident instead of .Net* I am trying to create a console application that computes the row and column sum and prints the elements with the resulting sums for each row and column.

[Code]....

My column sum code is currently showing the row sums. I need the column sums to display in descending order. So i know it would require a sorted array, but i'm not sure how to go about doing that given i can't get the correct values to show up. So I would need it to display as "Column sums are 12, 20, 13, 24, 51. " and then the next line would be "Column indexes are 1, 3, 2, 4, 5."

Importing CSV File Into Multidimensional Array

Dec 20, 2011

I can't seem to get the code structure I'm looking for when importing a csv file into an array. The CSV format in question is 69 columns, and unknown rows since it depends on the time length of the data capture. Over the past 3 days I have tried many methods and can output it all to a listbox, as shown below (column headers appear in order), however when I try to put it into an array it only reads the first column. Am I missing something in the declaration of the array, or do I need to use an arraylist? Every permutation doesn't seem to get the results I seek, or I just plain crash the program.

Sort A Multidimensional Array By The 3rd Column?

Oct 3, 2009

Dim array1(9,2) as String

So basically, 10 rows and 3 columns and say I want to sort them by the values in the 3rd column.

Each row is essentially a record of data and must be kept together.

Now I know that you can't use the array.sort method but would I have to use a bubble sort or something for this?

What's a good way to manipulate the records while still keeping each row linked together somehow.

VS 2010 SQL Database To Multidimensional Array?

May 15, 2012

First time I've had occasion to do this, but how would you represent the data in a SQL database table in a multidimensional array? I've heard tell of multidimensional arraylists but have no idea how to use them.

Here's what I have -

The table is 15 columns across and a varied amount of rows depending on the query.

rawData is an arraylist. finalData is an array.
Dim myReader As SqlDataReader = sqlcom.ExecuteReader
While myReader.Read()

[Code].....

Obviously, this gives me a long list of all the data from the query. I want to break it in rows.

While Loops - How To Initialize Multidimensional Array

Jul 12, 2011

I am trying to initialize a multidimensional array. Here is my syntax; this does not create errors but it does not store all values either. Although it correctly prints out all records in this snippet,

dFirstWeek = CDate(FirstWeek)
dFirstWeek = DateAdd(DateInterval.WeekOfYear, -1, dFirstWeek)
Dim dFirstDay As Date
Dim arrWeekYear(5000, 1) As Date
Dim i As Integer = 0
Dim j As Integer = 0
[Code] .....

But this time, only one "j" record appears per "i" record. Why is this? And then after these few records, many dates resembling null dates appear: "1/1/0001". So why do all records appear in upper section, but not from lower? Did I insert values wrongly into this array? And it does not have to have fixed number of rows, just a fixed number of columns.

Convert String Containing Upper ASCII Characters To Byte Array?

Oct 9, 2008

How to correctly convert string containing upper ASCII characters to byte array besides looping through each character and filling the array using AscW(chr)?I know I can do something like:

Code:
Dim bSourceData As Byte() = System.Text.ASCIIEncoding.GetBytes(sourcedata)

But this only works for lower ascii characters (0-127).Instead of ASCIIEncoding I can specify encoding myself (System.Text.Encoding.Getencoding(encoding).GetBytes(sourcedata)). But I have to specify correct encoding in this case, otherwise most of special characters are converted to "?". What should I do if I don't know the encoding?
