How To Code This Voting And Storing Into An Array Program
Nov 29, 2010
note, this is homework. It's not worth much, but i really need to learn how to store things in arrays. my biggest confusion is that i have no idea how to store something in an array, have the program run again andcontinuouslybuild the array andthen display the array in its current state (by like clicking a display poll button) and then still allow it to build more once more data is entered.Here's the whole assignment. I don't really understand how to start it and the problem above is my biggest frustration!ite a Visual Basic application that can be used to determine the best Super Bowl commercial. The choices are as follows: Budweiser, FedEx, E*Trade, and Pepsi. The application should allow for the user to enter a voter's name, gender and select a commercial from a list.
Create a Vote structure that will contain the voter's first name, last name, gender and the selected commercial. Each time a vote is entered, the information should be added to an array of Vote structures.Provide the ability to save your data to a sequential access file. The program should also be able to read an existing file of vote data into an your array of Vote structures. Doing so, should eliminate any data that may have already been in the array.

i want to users to be able to vote for their favourite soft drink. They will input the names of the soft drinks through the use of an inputbox, the names input are stored in an array. what i would like to do is count the votes given to each soft drink. How would this be done, please provide example code if possible.
p.s. i tried using a listbox and failed.Well during the set up of the program they will input the names of all soft drinks up for voting, and then all the soft drinks input wll be displayed in a list when the voting take place.

there is a private server that i like, and if you vote for it, you get points. however the problem is, it wont let you vote again until another 12 hours. do you think its possible to make a program to trick the website into thinking its been 12 hours? possibly messing with the html or something?? changing your computer time or using proxies dont work.

I have a quiz I am building that randomly picks the questions from the database and displays them to the page. It seems like it might be hanging with the logic I have on the page_load.I am storing the questionid in a session comma delimited and keep looping through to get the next randomly generated number that isn't in the session.

I need to construct a small program that "stores" entered test scores into the program then when a button is clicked, it will display the scores with the appropriate names in the box below. The values are the names "Brian" "james" "jimmy" "jock" and "gok" and there are two test scores "main test" "small test".. I need to be able to "store" these in a "database" and then when the user clicks "show marks" it displays all the names with the marks in a table format. I'm totally screwed and i dont know where to start..I already have done a little coding for the gui such as a password entering system and all that works, all I need now is this storing thing.

I'm having trouble trying to put together some code for an array. What I'm trying to do is get data entered from a text box and store it in an array.What I then need to do is take the entered data and make it appear in reverse order to what it's been entered and show this.

I have a whole bunch of information that has been parsed from a web page and i want to insert the data into a multi-demensional array and the compare the data of a certain array element to another array in the same format to determine which is missing/added.So if i have this:
Type of animal | Color | Age
Cat, Brown, 15
Dog, Pink, 6
Fish, Orange, 4
[code].....
I only want to compare the type of the animal and the color and age is irrelevant.I want it to let me know whats missing and what's been added.Sounds bizarre but yeah. It doesn't need to be arrays, it's the only thing i know of though.

I have a piece of code written in Visual Basic:
Dim n As Double, i As Integer
n = 4
Dim Ramp_length(1 To 4) As Double
For i = 1 To n
Ramp_length(i) = Cells(13 + i, 5)
'Cells(65 + i, 7) = Ramp_length(i)'
Next i
Is there a way I can reproduce the result without declaring the array with a "fixed" length? I eventually want the code to read off a column of data with unknown length and store it in an array of equal or smaller length so it can be altered.

Recently I started a project with the goal being to have text that was inputted into a textbox stored within a three dimensional jagged array. The idea is that every time a button is pressed, whatever text that is inputted into the textbox is split into separate elements, where each word occupies its own element in the array. So for example, if a poem were entered into the textbox and the button clicked, each word of the poem would be assigned to a discrete element in the vertical dimension, and each line of the poem assigned an element in the horizontal dimension. After the text is stored into the 3D jagged array, the text should be cleared from the textbox and a counter should then ensure that on the next button press, the new text inputted into the textbox is stored in a discrete element of the array. Below is the code I have written so far, but I know that I am far from having anything might accomplish what I have just described.

I'm trying to get a complete understanding of Objects . Namespaces etc and think I'm pretty close.I've created A basic Vehicles class and a car class that inherits Vehicle.Through user input I've created several cars and displayed the information in a listview.My question is what is the best way to store my cars (don't say garage!) so that if a user clicks on the associated entry on the list box that they can then alter that specific instance.

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

"I need to create a program that will allow the user to enter in 10 test grades from a class. I need to store these grades into an array, and use a loop to add up the total. Then I'll need to output the average, and the letter grade for the average using:

In the program I'm working on, there is a 'sign-in' form that pops up for the user to enter first name, last name, and DOB. What I want to do is STORE that information in a text file for FUTURE use by the program (i.e. displaying a list of all previous users of the program).I already know how to use streamwriter to write text to a file, but I would like for the text file to be stored within the program files and also for a new user's data to be appended to that file every time.
Do I simply add the text file to the project files? When I do that, its path is 'My Documents'. How will that affect the program when I publish it? I guess I just don't yet understand what happens when the program is finished and published. The code for the 'Submit' button on the sign-in form is pasted below. At the bottom, I've put a comment to indicate where I want to store the data to a file.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim TxtBox() As String = {TextBox1.Text, TextBox2.Text, TextBox3.Text}
For i As Integer = 0 To 2

I'm rewriting a legacy application in .NET. In the earlier version, I used a few control .INI files that could be edited by the advanced user to provide variation in certain program options. (The program also permitted override of these same variabes via menus and such.) I used the API functions to read the .INI files and rewrite them to alter the user's environment for subsequent runs.

I have an ArrayList that stores 100,000+ numbers inside of it. Each number is 10 digits in length or smaller. The program itself has data input into it, of which it loops through the user input to see if any of their numbers are already in the array using if ArrayList.Contains(userinput).
It would appear that when having an ArrayList of this size a LOT of memory is being used. Would there be a faster way to run this, E.g. Database or If TextFile.Contains(Line)?
