I am using VBNET2008 to develop Window Application. I was requested by Business Analyst to create a MultiDimensional Array containing CustID(Integer) and CustomerName(string). I do not know how to declare the MultiDimensional Array VARIABLE as Integer and string.
View 2 RepliesI 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.
For a To-do list program, I am trying to use something like this to get the textbox (txtlast) to show the string held in the array, but the text box just keeps coming up blank..... why is this?
txtLast.Text = Arrnumbervalue(IntYear, IntMonth, IntDay, IntHour)
I currently for the life of me can not get this to work.[code]Days(num).openTime(0) = New Date() 'Which gives the same error as openTime @ 0 has not been created as an array object (I'm assuming)Which leaves me completely lost because I've never had issues assigning initializing 1-dimensional arrays but this i just confusing the heck outta me. If anyone knows how I can initialize the 2nd part of the array (Days(num).openTime(0)) I would love to learn from you.

1] Is there a way to declare an array of mixed type [e.g.] column 1 as string, columns 2 through 5 as integer.
2] Is �Dim myArray( ,5 ) as type� a valid statement and if so will it result in a 5 column array of unspecified length?
Why doesn't this work?:
Dim sarray() As String = Nothing
Dim inc As Integer = -1

View 1 RepliesI'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.
[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 have an integer array with 4 indexes. What is the easiest way to get the sum of all integers in the array.

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.

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.
I am trying to use a simple quicksort routine for a multidimensional array but cannot figure out the syntax. I am stumped because it works fine in VB6 but no luck in .Net
