VS 2010 Difficulty Storing Textbox Input Into Jagged Array?
Jun 14, 2012
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'll try to explain what i'm doing here, i wan't look through a text file, adding certain lines to an individual array element. So i want to build an array with mcode, mTitle, mCredits, mSemester, moduleStats, currentYear <--- this information as an array element. So here is my attempt at the code,
Dim sr As StreamReader = New StreamReader("datasource.txt")
Dim line = sr.ReadLine() ' get each line and store it
Dim currentYear As Integer

I am having some problems with manipulating a one dimensional string array in VB.NET and would like My objective is to get 4 variables (if possible) from a file path. These variables are: myCountry, myCity, myStreet, Filename. All declared as string. The file location is also declared as string. so I have:
Dim filePath As String to illustrate my problem, and what I am trying to do, I have the following examples:
1- C:mylocationisUKBirminghamSummer Road his house.txt.

"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:
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D

That's all it needs to do. Here is some code that shows you that the only thing I know how to do is (allow the user to enter in 10 test grades from a class.) The rest I'm so lost on and have a crappy instructor. This assignment is due tomorrow, but the instructor is not available over the weekend.

I'm working on a reporting section of code for an inventory app I'm making for my office.I call a text file, read every line into an array then populate information pages with what has been pulled from the text file.For reporting, I want to read every text file in the directory, reading each one into a multidimensional array.Thus I can call and report on each item, i.e.ItemArray(i,2) would be all systems with Windows 2008 EE..I have code that lists all files in the desired directory and counts each file, so I eventually get counts of how deep I need the first level of the jagged array to be. but not until after code execution. Basically how can I write each array of data to the jagged array.[code]But I get a null reference exception. "Use the new keyword to create an object instance".

I currently have a VB.NET dll that returns a jagged array of double. This is the declaration:
Public Function CalcMatching(ByRef dataArray1 As Object,
ByRef dataLen1 As Integer, ByRef dataArray2 As Object,
ByRef dataLen2 As Integer, ByRef matchingType As String) As Double()()
It works well inside VB.NET, but when I insert it into a VBA project, I noticed that after the execution of the funtion, while retrieving the data, the "Type mismatch' excpetion is raised inside VBA.I searched over the internet, but I could not find a delcaration of a jagged array inside VBA. is that possible? If yes, how can I do it?

I am trying to make a jagged array that has,
3 columns
with 5,4,4 rows respectively
that each have 2 rows
that have a varying number of rows, for example 6,9,5,6,4 I have the first part setup but I don't know how to get to another level of the jagged array.
Dim potentialStructure()() As Short = {New Short() {0, 1, 2, 3, 4}, New Short() {0, 1, 2, 3}, New Short() {0, 1, 2, 3}}
And how would I access an element at say, the lowest level?

I need to scan database and insert its values into an array. But I'm having some difficulties in handling null values and array.
The database looks like this:
0 1 2 3 4
30 31 32
33 34
36 37 38 39 40
38 39 47 48
I want to make array rr_item which gonna looks like this:
arr_item(1)={0,1,2,3,4}
arr_item(2)={30,31,32}
arr_item(3)={33,34}
arr_item(4)={36,37,38,39,40}
arr_item(5)={38,39,47,48}
Every code I've tried result in error everytime I tried to insert null value into any kind of c=variable, including array which I want to use. And I'm not quite sure with what I'm doing in jagged array I want to build.
sql_list = "SELECT * FROM retail"

So I have a function that looks up values in a jagged array, and it goes like this:
Private Function Lookup(ByVal Search_path As String) As Integer
Dim i As Integer = 0
Do Until MasterIndex(i) Is Nothing 'throws an exception here

Problem is, when I test this with an empty array, it gives me the error of Index was outside the bounds of the array at line 3. How do I fix this?

I have a scenario where I am trying to generate every combination of value from a jagged array - for example..[code]So all in first array associated with all in second array.I have created my jagged array with the values but I can't work out how to iterate through it and create all variations - I can iterate, but only get each value once at present.Also on a related note this could do with working in the case of more than 2 arrays - i.e. a multiple number of arrays within the jagged array.

i have used in vba 3 dimensional jagged arrays where i had up to 10000 rows. i am now transferring this to vb.net and learnt that it would be better to work with lists. the dimensions are such as (30, 10000, 30). how would i structure this by using lists?

I'm trying to make a program where user can input data from a textbox into an array and when the user hit the enter key, it compare it to a data grab from a text file. Here is my code so far:
Private Sub TextBox_KeyDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox.TextChanged
Dim input As String
[Code]....
I got the part where the program can graph data from text file and put it into an array called "varia3". The part I could not get is allowing user to enter data into the textbox. When I run the program, the sec I try to enter a letter or number into the textbox the program ended.

Put simply, how do I make a simple GET request with a few headers and read the data back! I am very, very stuck in a hole right now..

I'm having a strange difficulty. Here is the order of events:User presses button on form1 New Form object is created for from 2 New form object '.show' command is fired Form 2 opens correctly In the Load Event of Form 2, the form attempts to do various things in a try, catch, finally clause On catch, I close form2 down '.close' as it cannot be used as something has gone wrong with the execution However, my problem is this. It is acceptable for things to go wrong on the from 2 load event which is why I have implemented the try - catch functionality. However, when I close the form2 down as a result of the problem, a real error ocurrs 'Cannot access a disposed object' and the VB IDE refers me to Form1's '.show' event for Form2.
It is almost as if the form hasn't fully 'shown' before I am closing it down. Does anyone have any idea what the problem is here? Do I need to close down Form2 ourside of it's Load event handler so that Form1 thinks it has loaded correctly?

I'm working on a program dealing with jagged arrays.Code is below.The FindPath() function works perfectly.It essentially randomly chooses an action from 3 possible choices.The goal of this function is to make it to position (3,3) from (0,0).Sometimes it makes it, sometimes it doesn't.It gives up after 2000 moves.
The PushButton() function is where I have the problem.I want to run the FindPath() function 2000 times, and return the resulting list of moves into intLists()(), my jagged array.I want to use
intRuns = 0
For intRuns = 0 To intLists.GetUpperBound(0)
lstMoveList.Items.Add(intLists(intRuns).GetUpperBound(0)) 'here is where I get the problem.
this section of code to dump the number of attempts it took into a listbox on the main window.I do this at the bottom of the FindPath() function, but that is for testing purposes only.I eventually want to take the successful attempts and manipulate those, so eventually I get the minimum possible number of movements to get from the starting point of (0,0) to the ending point of (3,3).
Function PushButton()
Dim intRuns As Integer
Dim intLists(2000)() As Integer[code]...............

How do I prompt the user to input elements in a two dimensional array? And how do I then save the output?I've figured out how write and print a program where the program provides the elements (see short version below), but I can't work out how to get the user to input the elements instead.

Solfa(0, 1) = 12
