Declaring Two Dimensional Arrays?

Feb 16, 2009

I am trying to set up a number of two dimensional arrays that will be accessed from several forms in the project. I have set up a module to declare all public variables.When I declare the array (Using variables to determine the size of each dimension), when I go to run it, I get an out of index error.If I declare it them as public variables within the form, I don't get the error but then the input cannot be accessed from other forms.Am I completing incorrectly in the module or is there something else I ought to be doing.

The code within the form is

Dim Boardresult(NumBoards, Numteams) As Integer
Dim compass(NumBoards, Numteams) As Boolean

Where NumBoards and Numteams have been input and stored previously.

2 Dimensional Arrays Of Control Objects

Jul 11, 2009

I have the read the article "Creating Control Arrays in Visual Basic .NET" (link: [URL]) and I its very good and useful code for 1D array of objects. What if someone wants to make a 2D array of control objects. For example creating a "table" of 8x8 buttons that will be able to change properties by using the arrays x-y coordinates. Something like button(x,y). backcolor.black or similar.

Saving 2-dimensional Arrays To Settings?

Jun 30, 2011

I have two different 2-dimensional arrays. I assume the setting i need to save them to is a string setting, as is the cast with regular integer arrays. The first 2-d array I need to save is an integer, the second a decimal.

Let's say the settings are called my.settings.2darray1 and my.settings.2darray2
Let's also say the arrays are:

vb

dim 2darray1(50, 99) as integer dim 2darray2(50, 99) as decimal

What would the code be to load each array and save each array?

Create A Tic-tac-toe Game But None Of The Tic-tac-toe Tutorials Use 2 Dimensional Arrays

Mar 14, 2010

I am new to VB, trying to create a tic-tac-toe game but none of the tic-tac-toe tutorials use 2 dimensional arrays. Since tic-tac toe is 3x3 I created 9 buttons and want either an X or an O to appear depending on where the user clicks. I want one set of instructions to handle the multiple buttons. I was told to use Case statements.

This is what I have so far. Not sure how much is right but hopefully it gives you an idea of what I am looking for.

Grasping The Concept / Context Of Two Dimensional Arrays?

Oct 29, 2010

I am having difficulties grasping the concept / context of two dimensional arrays. For the assignment I am working on I am required to use radio buttons to allow a user to vote if they like or dislike an item from a combo box. The contents of the combo box have been populated through the IDE via tht item property.I understand how to set up my rows and columns, which will be, (0 to 4), (0 to 1). The trouble I am having is how to record and display the votes and have them correspond to the selected item from the combo box. Can anyone give me an example of how something like this works?

Sharing Multi-dimensional Arrays Across Different Forms In VB?

Jul 9, 2011

I have a very simple 2D array, it holds a list of song titles, their genre, and their runtime. frmMain loads the array from a text file and allows me to manipulate it and boil it down to a desired (implicitly sized) playlist. i want to THEN pass that playlist array to a second form, frmPlaylist The problem i'm running into....When frmPLaylist calls the Property from frmMain I receive an error that VB cannot convert the string value to a two dimensional array. Simplified...frmPlaylist is all locked and ready to receive a 2D array, but frmMain seems to only be sending a single string variable. on frmMain

Public ReadOnly Property PlaylistOut() As String
Get
Return mstrTimedPlaylist(,)

One Dimensional Arrays (accumulate The Value Of Each Item Of The Array) And Classes

Dec 12, 2010

I have written a class for my one dimensional array The idea is to collect user information, put the info into an array and accumulate the value of each item of the array so there is a running total. The problem is that the code is not totalling the array when my btnSum is clicked or maybe at all. I am getting no errors, but I am also getting no total.

Using Parallel One-dimensional Arrays To Calculate A Letter Grade?

Jul 27, 2011

The exercise prior to this one had us use two parallel arrays that store a letter grade (A, B, C, D, F) and the minimum points needed for each grade. The user input the points earned by the student and the program shows their letter grade. It took a minute, but I got that one done, and it does what it's supposed to do.This exercise has us modify that exercise to ask for the (via InputBox in MainForm Load event) total points possible. The grade is then determined by percentage of the total points possible. For instance, if x is the user input, an "A" would be 90% of x.

Two-dimensional Arrays - Display The Total Bonus Paid To All Salespeople?

Apr 24, 2010

I am doing in my Visual Basic Reloaded:second edition school book. Ok here is all the information the case problem gives me and what it wants me to do.JM Sales employs 10 salespeople. The sales made by the salespeople during the months of January,February, and March are shown in Figure 8.52. The sales manager wants an application that allows him to enter the current bonus rate. The application should display each salesperson's number (1 through 10), total sales ammount, and total bonus ammount. It also should display the total bonus paid to all salespeople. Be sure to use one or more array in the application.Then it gives you a table with the salespersons 1-10 sales amount january February and March.(this is the figure 8.52)Here is a duplicate table of it below.

Salesperson January February March
----------- ------- -------- -------
1 2400 3500 2000
2 1500 7000 1000
3 600 450 21

VB6 Used Recordsetsor Arrays - .Net Framework In VB2010. Datasets, Dataviews. Tableadapters, Arrays. Enums ?

May 9, 2010

In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.

The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

Passing Arrays Through Fortran Dll From App Turning To Single Element Arrays?

Feb 2, 2010

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

.net - 2-dimensional List Is Almost 1000x Slower Than 1-dimensional List?

Feb 12, 2011

Consider the following code:

Dim arr1 As New List(Of Double)
Dim arr2 As New List(Of Object)
Dim timeStart As DateTime = Now
For x As Integer = 0 To 1000000

[code]....

It involves 2 lists. The first one is 1-dimensional, the second one is 2-dimensional.The first routine (which operates on the first list) completes in about .015 seconds. The second routine (which operates on the second list), however, takes almost 10 seconds. The only difference is that the second list is 2-dimensional.Is there a way to speed this up or am I doing something wrong? I have a program that requires several 2-dimensional arrays and it's running extremely slow right now. How can I speed it up so I get the same feedback that I'd get if the lists were 1-dimensional?

VS 2008 Copy One Dimensional Array Into Two Dimensional Array?

Feb 17, 2010

I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.

I can get each line into a one dimensional array using Split(Var, Chr(10)).

I'd like to make it a two dimensional array where the second dimension contains each comma separated value.

I've got

Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String

Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.

For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter

But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.

The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?
