Multidimensional Array - Creating A Variable For A Grid In .net?

Sep 6, 2011

I need to store elements in a multidimensional array. Specifically, I need to save "tiles" to a grid (e.g.Grass at x:2 y:5, Dirt at x:3 y:5, etc.). Using a multidimensional feels very hacked up and is very glitchy (having to resize my arrays and having to create new ones were they are non-existant). Is there some kind of element made for this? Something I can say obj.getPos(2,5) and get my Grass Element and use obj.setPos(DirtObj, 3, 5) to set it to my Dirt Element?

I'm just wondering if there is something easier to use than multidimensional arrays in vb.net, that is all.

Multidimensional Array - Multi-column Data Variable Object?

Sep 25, 2009

I want to create an in-memory object in VB.Net with multiple columns. What I am trying to do is create an index of some data. It will look like:

Row 1: 23 1
Row 2: 5 1
Row 3: 3 38
...

I know I can use a rectangular array to do this, but I want to be able to use indexOf opearations on this object.

Creating An Array With A Variable Value?

Mar 22, 2010

i want to declare an array with a name that is the value of a variable. I need to do this because i want to create arrays from a text file that i'm reading.Basically, if someone could make this work then i should be able to change it to fit my use.

Dim var1 As String = howdy

Dim var1() as Integer

In this case i'd like to be declaring an array with the name 'howdy' that stores integers. In reality i'm looping a bunch of read names and would like to create an array for each name i read- but i'm quite capable of sorting the rest.

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

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.

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.

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.

Create A Multidimensional Array That Contains Arrays Of Different Lengths?

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]]
