VS 2010 Array With Redim Preserve?
Apr 4, 2012[edit]Sorry I left a bad title in this thread - confusing![/edit] Been a long time since I used an array - they are so limiting...But I need to build a simple string array - that I'm passing to a C/C++ function.
Is there any other way to do this other than keep REDIM PRESERVING??

Redim Boolean Array Vs Enumerate And Set?
Jul 23, 2010In a case where you would like to reset an array of boolean values what is faster, rediming the array or enumerating and resetting the values? I have run some tests and they seem to suggest that a redim is a lot faster but I am not convinced that it isnt a result of how I'm running the tests.
My tests seem to suggest that redim is nearly twice as fast.So could anyone care to comment on which is faster and why? Also would you expect the same result across different languages?

Can't 'Redim' Referenced Array By Reference Object
Jan 16, 2011I have an object array that I want to reference. The object array is in a deep set of classes so it takes class1.class2.class3.class4 just to get to it. I need to use this many times throughout my code so I figured I'd just create an object i.e. Dim Obj as Object and reference this array:
Dim Obj as Object = Class1.Class2.Class3.Class4.ObjectsArray
Problem is I can't resize the referenced array, by using the reference. The following does not work:
Redim Obj(5)
How come it isn't referencing my object array completely? is it because its the same object type?

View 8 RepliesArray Dimensions - Error Message 'ReDim' Cannot Change The Number Of Dimensions Of An Array?
Oct 20, 2011I'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double()
Dim i, j As Long
Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.

VS 2008 - 2 Dimensional Array - Error: Redim Can Only Change The Rightmost Dimension
Sep 22, 2011I have a gridview in my asp.net website that and I use vb for the code behind. Each time a row is bound an even called the Gridview_RowDatabound event is fired. So what I am doing is looping through all the cells in that row: [Code]
Problem is I get an error saying redim can only change the rightmost dimension. It would suit my needs to change both dimensions here as my final result will be to total each column in the array. what other method can i use if arrays don't suit this task.
Preserve An Array Inside A Class Method?
Mar 30, 2010I have been learning about OOP and classes from a book and one of the question is the book has asked to create a simple Saving/Checking accounts Program. The question says that most of the functionality must be done through an Accounts Class, and this Acoounts class must inherit certain private fileds from an base class 'Transaction.
The question also says that data from the Saving/Checking accounts Program must be read to and from a text file, and these functions must be done within the Acounts class.
i have done everything the question asks to the best of my knowlegde and understanding but when it comes to storing and retieving data from the textfile i cannot utilise the array i created to store the textfile data onto it.
Bank Account.Write a program to maintain a person's Savings and Checking accounts. The program should keep track of and display the balances in both accounts, and maintain a list of transactions (deposits, withdrawals, fund transfers, and check clearings) separately for each account. The two lists of transactions should be stored in sequential files so that they will persist between program sessions.
Consider the form in Figure 11.12. The two dropdown combo boxes should each contain the items Checking and Savings. Each of the four group boxes corresponds to a type of transaction. (When Savings is selected in the Account combo box, the Check group box should disappear.) The user makes a transaction by typing data into the text boxes of a group box and pressing the button. The items appearing in the Transactions list box should correspond to the type of account that has been selected. The caption of the second label in the Transfer group box should toggle between "to Checking" and "to Savings" depending on the item selected in the "Transfer from" combo box. If a transaction cannot be carried out, a message (such as "Insufficient funds") should be displayed.
The program should use two classes, Transaction and Account. The class Transaction should have properties for transaction name, amount, date, and whether it is a credit (deposit) or debit (withdrawal/check). The class Account, which will have both a checking account and a savings account as instances, should use an array of Transaction objects. In addition, it should have properties for name (Checking or Savings) and balance. It should have methods to carry out a transaction (if possible), to display the list of transactions, and to load and retrieve the set of transactions into or from a sequential file. The events InsufficientFunds and TransactionCommitted should be triggered at appropriate times.
Hint: In order for an Account object to display a list of transactions, a list box should be passed to a method as an argument. The method might be declared with Sub EnumerateTransactions(ByVal lb As ListBox).
Here is my code. I am sorry this code is basic and unedited.
Public Class Form3
'load contents of Text file into the listbox when first loaded
'store data in file into array of accounts, record no. counts

Multidimensional Array Within A Structure
Oct 23, 2009I'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.

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, 2011I 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.
