Create A Multidimensional Array That Contains Arrays Of Different Lengths?
Jan 1, 2011
Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python).
Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case?
e.g The above code would create an array like this:
[[0,0],[0,0]]
but would it be possible to create this:
[[0,0],[0,0,0]]

I am working on a program that opens a .txt file, finds the length of each line in the file, and then outputs the minimum and maximum lengths. For example, assuming this is the .txt file I am opening:
2789304
293048203
27598493
[code].....
I would like to return something like this:
Minimum length: 6
Maximum length: 9
I cannot use arrays for this assignment. I figured out how to get the maximum length but cannot figure out how to get the minimum. Am I going about this the right way or is there an easier way to do this? Here is what I have thus far:
Dim FileName As String
Dim FileReader As StreamReader
Dim FileLine As String
[code].....

I just made a multidimensional array that was 1024 x 1024 x 1024. I get an OutOfMemory exception. What is the largest size multidimensional array that is safe to use? I'm doing this in VB.net so all .net answers are acceptable.
EDIT
When I said safe, I mean, a good size for just about any computer. What size would run smoothly on a 32bit operating system. I didn't realize that the 1024 size was 4G. I'm hoping for something a 16th of that.

is there in VB.NET something like this in php?:
$var["a1"]['name']="Mike";
$var["a1"]['nick']="MMM";
I tried hashtables, dictionary, lists and arrays in .net, all I could get is a simple key=>value array Is there a simple solution if not, is there a class or something for this?

Currently, I am working on a personal project of mine to create a Pokemon Battle Simulator, mainly because I wanted to see if I could. I have created a multidimensional array used to hold all the information needed for each Pokemon I add (Currently it is only two Pokemon) The code for this is as follows:
Public AllPOKEMON(,) As Pokemon = { _
{New Pokemon("Charizard", 6, 2, 10, 360, 293, 348, 280, 295, 328)}, _
{New Pokemon("Venusaur", 3, 5, 8, 364, 289, 328, 291, 328, 284)} _

I'm looking for something similar to using vectors and pointers that I've used before in C++; unfortunately, it doesn't seem like there's an equivalent function in VB.net.What I have is a copy of the array behind a multi-line Rich Text Box, and I need to separate the words from each line (or element of the array) so I can analyze each one separately.In C++ I would do something like this, so I could continuously expand as needed:

Is it possible to have a 2 dimensional array of a type struct such that the size of the last dimension can vary by element of the first?eg:-structure mydatadim param1 as integerdim param2 as byteend structuredim main_array(100,10) as mydataThen at anytime change the size of the last dimension like...redim main_array(10, 5)redim main_array(15,7)leaving all other array entrys' last dimension unchanged and independent??VB2005 starter

EDIT: SI have a web service which uses a class of functions in order to return data used in various business processes (via InfoPath). One of the functions takes a given SQLCommand object and executes it into a SQLDataReader. Now depending on the SQL command text used this may return one or many rows of one or many columns. So what is the best class for this function to return bearing in mind it needs to be serialized by the web service.
My existing code is:
Dim array As New ArrayList

I have an array of strings such as "blue", "green", "red" and I wish to sort them so the longest string comes first and the shortest last.
Currently I am creating another array with the lengths of each string in the array in the same index positions and using this array as the key array to sort by as can be seen below, but I think this could be optimised into one line perhaps?
Dim colours() As string = {"blue", "green", "red"}
Dim colourslength() As Integer
For i As Integer = 0 To colours.Length - 1
[Code].....
Edit: just realised I defined colours as a list in the example code, it's an array in my actual code.

I have a multidimensional array which will hold 3 bits of value and value will be added through a loop by reading from db. When it come this line of code:
*MenuAccess(.Fields("GROUPNO").Value, .Fields("ITEMNO").Value, .Fields("SUBITEMNO").Value) = OKNO*
It's hitting error, 'Object reference not set to an instance of an object.'
Public MenuAccess(100, 30, 50) As Boolean

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)

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.

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

Is there at all a way to sort (numerically) a multidimensional array?
I have an array that is as follows `dim points(23,1) as String`
The first dimension of the array has the players names in, the second dimension of it has their cumulative points, so I want to sort the array by points and maintaing the correlation of players name to points

* 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."

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.

I am trying to make a jagged array that has,
3 columns
with 5,4,4 rows respectively
that each have 2 rows
that have a varying number of rows, for example 6,9,5,6,4 I have the first part setup but I don't know how to get to another level of the jagged array.
Dim potentialStructure()() As Short = {New Short() {0, 1, 2, 3, 4}, New Short() {0, 1, 2, 3}, New Short() {0, 1, 2, 3}}
And how would I access an element at say, the lowest level?

I have a multidimensional array (not jagged array) that saves data from rows and columns of an excel spreadsheet. After it completes recording the data from Excel, I need to pass the array to another function.I understand how to pass a jagged array, but not a true multidimensional array.
Can someone point me in the right direction? I've done some searching on this site, and others, but most of the info only includes single dimension arrays or jagged arrays.
