Integer Arrays - User Enter In Big Integers Using - Two Parallel Arrays
Dec 10, 2009
My assignment is to have a user enter in big integers using what i think is two parallel arrays. I got this far but now im stuck. I think i need to actually convert the text box input into an array but i do not know how to do that. I am all over the place in this project.

Ive been working on a checkbook application for my visual basic class and I'm a little stumped..
To preface, the values I need to mess with include:
transaction type (checking or deposit)
DTP
check number ("dep" if deposit)
[Code].....
Below is the Change I need to make to my program...
"You will create a set of either collections or arrays (your choice but use just one or the other--don't mix them) scoped at the form/module level. These structures will store all of the input data needed for your checkbook transactions except for the running balance which will continue to be stored in a single module-scoped variable. That is, every input that users made in Assignment 3 will be stored in one of these arrays but you will not store any calculated values. You will not store the transaction type but will store "Dep" or a number in the check number array which will also indicate the transaction type. The Record button will add the current sale's data to these structures using either ReDim for the arrays or an appropriate technique for the collections. (You must ReDim your arrays so that the have just enough space for the data that is in them. Declaring the arrays with a large size with no facility to resize them is not allowed. Don't forget to use the ReDim Preserve syntax to retain the existing array contents when you resize them.)"
I don't know if I make a single array for all the values or if I create a separate one for each. If its a separate one for each I don't understand why an array is needed.

how can i sort too parallel arrays?
[Code]....
Those are the two arrays now when i try array.sort(strflavor,decamountsold) or array.sort(decamountsold,strflavor) they are not arraigned properly. I am trying to get them to sort by which flavor sold the least and which flavor sold the most. However when i sort them, the flavors are not matching up with the decimal values.

I just learned basic arrays, I'm writing a program the allows Professor Carver to display a grade based on the number of possible points he enters in the inputbox (strMax). Then the user enters the points he earned in the textbox (dblPoints)
Then I solve the percentage. dblResults = dblPoints/CDbl(strMax) The first step is to store the minimum percentage points in one dimensional array. I did that. The second step is to store the grades in one dimensional array. I did that. The arrays should be parallel arrays. Having trouble with it It then should display the corresponding grade from the strGrades array Not done. I'm having trouble to display arrays in that are parallel.

getting started with creating an index search for parallel arrays. When the user enters the specific "code", and presses enter, the information in the other arrays should be displayed based on its matching index. I'm pretty sure I use "For i = " but I'm lost. I have my arrays set up like this:
Dim code(9) As String
code(0) = "A"
code(1) = "H"

In Visual Basic 2005 is it possible to parallel sort three or maybe four arrays? I have a function that is trying to accomplish this but it only parallel sorts the second array with the Array that it is being sorted with. Here is the code
Sub ParallelListBoxSort(ByVal byList As ListBox, ByVal otherLists() As ListBox)
Dim ii As Integer = 0
Dim a As Integer = otherLists.Length
[Code]....
'listToArray' is just a function that converts a list to an 1-Dimensional array and 'setArrayToListCollection' just puts the array back into the appropriated list.

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.

I need to know how to code a windows application program that will make it possible for customers to place orders online. Customers will have access to menu using a combobox,containing items available. The text file contains all menu items and the price of each item, as well as number of orders for each item. The file is created with a notepad containing 5 menu items.the first line contains the name of the item,second line contains the price and the third contains total number of orders which initially is 0. So far so good i know how to check if the file exists or not,and populating the the combobox, but ther's an instruction where i have ensure that the number of menu items does not exceed 100, and if so,should display an error message.and should validate to ensure that the total number of orders is>0,if not,re display the input box with a suitable message. Then on the save(menustrip),should write the whole textfile from arrays in memory,clear the combobox,display the message. Also has a process payment button where it should read through the arrays with a for next loop,then shouold write function called amount due,which recieves the total orders as a single data type,where the value for amount due is calculated as total orders*price.CAN SOMEONE PLEASE HELP ME OUT SINCE IM A BEGINNER IN VB2005.

I have to write a program using 2 parallel arrays representing grade point and grades. The grade points range from 0 to 500, however, we are only to use the minimum points per each letter grade in " points " array. This is shown in the code below. You then enter a number from 1 to 500, representing the grade points, and in turn it spits out your letter grade.My problem is this. When I enter a number, say 200, I get a letter " D " grade instead of an " F " grade. It appears that every number range I enter gives me one letter grade less than what it is supposed to be. Also, any number 450 to 500, representing an " A " grade does not even register in my Grades Label.

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 ?

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

the statement Dim state(49) As String and maintain a list of certain states. The list of states should always be in alphabetical order and occupy consecutive elements of the array. The buttons in the program should give the user the following options: (a) Take the state specified by the user in a text box and insert it into its proper position in the array. If the state is already in the array, so report. (b) Take the state specified by the user in a text box and delete it from the array. If the state is not in the array, so report. (c) Display the states in the array. "
Private Sub states_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have 2 arrays. One is an array of images other an array of numbers. The images are card faces, (Card(i)), the integers are the corresponding values of the cards (Value(i)). I want to associate the card face with a corresponding value. However, everytime I do what I think is correct, I get an error stating that I cant convert an image to an integer and visa versa.

In the player vs computer tic tac toe game I've been working on there are 2 boolean arrays (one for the computer and one for the player) that track which cells have been taken. When all other moves have been exhausted I would like the computer to play a random cell. To do this I am trying to gather the indexes of all False values from the 2 arrays and add them to another dynamic integer array. The computer will then choose randomly from the new array. The two Boolean arrays are plyrTaken and cmptrTaken. The dynamic array is occupied.
Here I declared the arrays:
Public Class Form1
Private occupied() As Integer
Private plyrTaken(8) As Boolean
Private plyrPairs(14) As Boolean
Here I got the dynamic array ready for use:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
ReDim occupied(0)
And here is the code I have attempted:
For index As Integer = 0 To 8
If plyrTaken(index) = False And cmptrTaken(index) = False Then
ReDim Preserve occupied(UBound(occupied) + 1)
[Code] .....
In the last block of code I was just trying to print the contents of the array to a list box so I could see if it was working. Obviously, it's not. When one position is occupied the list box shows the occupied cell index with a Zero. This really shouldn't be there as I want only taken cell indexes to be sent to array and list box. When a second position is occupied 7 zeros are added to the list box. Kinda shows promise as 9 total cells - 2 is 7 but there should be index numbers other than zero to represent the cells that have been occupied.
Also, the indexes shouldn't keep adding on to the dynamic array I need a way to clear the array and resize it back to 0. I tried adding
Redim occupied(0)
to the top of the code but that didn't seem to work.

I am very confuse over a Raise Events example and using delegate as a function pointer: I am clear with this function pointer example program below which creates a generic sort function for sorting integer arrays without changing the main sort function.
' Returns True if need to swap
Delegate Function CompareFunc(ByVal x As Integer, _
ByVal y As Integer) _
As Boolean
Here are two alternative target methods for the delegate - one for an ascending sort and one for a descending sort:
Function SortAscending(ByVal x As Integer, ByVal y As Integer) As Boolean
If y < x Then
SortAscending = True
End If
End Function
Function SortDescending(ByVal x As Integer, _
ByVal y As Integer) As Boolean

I was wondering if anyone knows a built in method ( LINQ say or a LAMBDA expression or other way ) that you can compare2 arrays - collections that would be valid for an equivalent 3rd array - collection which is a combination of the 1st two.

I've searched until my eyes and fingers feel as if they are going to bleed. I cannot come up with the answers I'm looking for. I want to essentially create an inventory system without using a database (part of why the eyes are bleeding, keep getting directed on side tangents), that is fed by the user. IE, User enters a name of a product, it is added in to an array. As a designer I will not know the exact number of elements to be held within the array. The user will enter their chosen item in to a text box. So I'm looking for a way to take the value in the text box and add it to the array. I believe I would use the reDIM function to do this, but beyond that I've got nothing. I'm unsure of how to reference the value stored in a text box.

Create two arrays, ask the user to populate them and display both arrays Swap the contents of the arrays using loops and then display the content.
What is the best method to have the end user populate an array? I am doing this as a windows form. Have multiple text boxes that they have to fill out? Set the elements of the array to the text box values? And how to swap the contents at run time is something I am not sure of. Isn't there a Array Swap function or something? Here is what I have so far:
Note: the bottom section was a test..and it isn't working as expected.

This new form will ask the user to enter 10 values into a textbox and click ok after each value. These values are to be stored in an array and displayed in the listbox on the previous form.I am having trouble getting the values of the user to store into my array and displaying into a list box.

In this application I need to allow users to enter a month as integer (1-12) then use integer tryparse to validate that input, that seems to be the easy part. I need two create two functions, one that returns the name of the month and the other returns the number of days in that month. The arrays are supposed to be defined and initialized within the function so that the main program can take the user input and call the two functions, then return the appropriate values as output to labels. I am not sure how to declare the arrays in their appropriate functions and then how to call those functions to retrieve the right value from the function.
