Is it possible to have a multidimensional list? For example the equivalent of a multidimensional array by using lists. If so would it be done similar to the following?
CODE:
If not does anyone have some suggestions? It just seems that the above code is sort of sloppy and looks incorrect for some reason.
I have a class having 2 properties (both integers) and storing class into List collection.[code]Here I need return "TRUE". (values in "GroupNo" is not static and not in sort).How can we do that in vb.net?

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.'

Hi can someone show me an example of a multidimensional associative array in vb.net. Need array to hold peoples name, there age and a few other settings. Want to be able to use a Dictionary to use People.Add.

View 1 RepliesI 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.
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.

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.

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."

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 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'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:

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.

Array Declaration:

Function Call:
[Code]....
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.
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.and the rowsum code is showing a continuous sum, rather than a sum for just that row.
