VS 2008 Trouble With Multidimensional Structure Based Array

May 27, 2010

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.

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.

IDE :: Creating An Array Of A Structure Based On Existing Project?

May 1, 2009

how to write the code for my project.I am to base my new project on an existing one(existing one has code that works 100%)and create an Array of a structure that bascially holds the information from a summary form AND the totals from an AddToOrder_Click event. If you are still with me)... I cant figure out what the code is for my structure and Array so that I STILL have a Summary Form but I have an array that shows when I click my PrintPreview. So an Array is basically a "space" that holds information, like my summary form except it doesnt show until I click PrintPreview right?

If I just wanted to show the table then my code belongs in the PrintDocument1_PrintPage to show the array but the actual structure code belongs in the Click_Event of my AddToOrder? Please Please understand I AM NOT asking for anyone to write my code, basically I am asking for some clarification on what exactly creating an array from a structure is and therefore determing where the structure is to be placed in my code..

VS 2008 - Serialize Array Of Structure To XML

Jun 3, 2010

I desperately seek for a code sample to serialize an array of structure elements to a XML. To serialize a simple object of a structure I used:
Private Sub saveEntries()
Dim FS As New FileStream(path, FileMode.Create)
Dim XS As New XmlSerializer(GetType(personEntry))
XS.Serialize(FS, entries(0)) 'serialize first entry of an array - success
FS.Close()
End Sub

Structure looks like this:
<Serializable()> Public Structure personEntry
Dim name As String
Dim d, m, y As Integer
End Structure
Private path As String = "data_file.xml"
Public entries(2) As personEntry
But how to apply this to an array?

Converting Structure Within Structure To Byte Array For Socket

Aug 29, 2009

I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.

I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.

Public Structure MESSAGETYPE_OIP_Login
Dim Header() As COMMANDHEADER
Dim UserName() As PSTRING

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)

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.

Pass A Multidimensional Array To A Function?

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.
