Storing Data In An Array And Comparing It To Another One?
Oct 15, 2011
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'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.

Line 1: UserName (For User 1)
Line 2: FilePath (For User 1)
Line 3: UserName (For User 2)

I have a query in Access 07 that identifies the following fields: ContractID, status, start date and end date. For each contract, I've been able to search a network share and upload its corresponding file; however I need to skip the import and write a record to a table for contracts with the same start and end date. I've included a placeholder (in bold below), but how do I make the date comparison work? Do I need to create a multi-dimensional array for that or can it be done with the code I have?
Private Sub cmdRefreshList_Click()
DoCmd.SetWarnings False
'Create an array based on the true-up contract IDs.

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.

I got a value which is store in the array and i need to compare it. Which
if my user = 1,2,3,4,5,6 then ignore
if my user = 2,3,4,5,6 then i need to add in a ,1 which become 2,3,4,5,6,1
Here is my coding
user = dr("user_access")
dr.Close()
Dim splitX As String() = user.Split(","c)
For Each item As String In splitX
[Code] .....
Is there other way to compare the array or there is another better way to check?

I'm trying to compare images for a slot game, and I'm pulling images from an array for this, but I get the error message:
"Operater '=' is not defined for 'System.Drawing.Image' and 'System.Drawing.Image'"
If imgSlot1.Image imgSlot2 Or imgSlot1 = imgSlot3 Then
Points = Points + 10

First of all - It`s my first post here so welcome I have a short question.I have an array with strings values, and a datacolumn with values of the same data type. The question is - what is the most efficient method to find values which are in the array, but aren`t in the datacolumn?

Basically what I'm trying to do is this, I have 20 statements in a Select Case (right now they're just labels for my own testing), I have a random number generator that will generate a number between 1 and 20. Since I don't want the same statement to repeat during the individual run of the program I'm trying to generate a random number, then check it in a dupeCheck method, then if it isn't a dupe I'm trying to return it to the select case and put it in the array so that when I choose the next random number if it's the same the dupe check method will catch it and return a False boolean and then the random method will do a recursive call to itself to generate a new random number and the whole thing starts again. I'm populating the numbers into the select case just fine, but VB keeps telling me that my functions aren't returning values on all paths, and stepping through I can see that the recursion isn't happening and that it's just sending the repeat number back, but I can't figure out where my major issue is. I'll show you my current skeleton code for the "GuessOrDie" as well as the first manifestation of the code I wrote for it a couple of days ago (the old code had infinite recursive calls and array out of bound exceptions)
I would really love it if you guys could take a look and let me know what mistakes I'm making, I'm having big problems moving from FOR loops in java to For/Each loops in VB and I suspect that is a big part of my problem.
Current Code:
Public Class GuessOrDie
Dim questHistoryArray(19) As Integer
Dim indexCount As Integer

I have two array list same size, depending on the information gathered by previous functions. The size of the arrays range from 2 - 45 in length, both arrays always have the same length. I am trying to match one string in one array to another string in the second array. When they match then add Item to List.
Here is my
Do Until i = Arraylenght
info = Replace(myAL(s), " ", "")
SortedArrayList(m) = Replace(SortedArrayList(m), " ", "")
SortedLine = Split(SortedArrayList(m), "Price=")
If myAL(s).Contains(SortedLine(1)) Then
[Code] .....
This code works up to an array of not more then 4 in lenght, when working larger size array then 4, the minute it get to 5 I get this Error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

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.

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.

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 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.
