Reference A "line" In A Two-dimensional Array?

Oct 7, 2011

how do I reference (pass as a parameter) a "line" of the two-dimensional

Dim Values As Object(,)

I.e. I want to write a function that expects a one-dimensional array of Object, i.e. Object(), and pass for example Values(1) to pass the values Values (1,lowerbound) through Values (1,upperbound) to my function as a one-dimensional array.

Put 2 Different Fields On The Same Line/row/subscript Into A One-dimensional Array Or List?

Nov 28, 2011

I need to put 2 different fields on the same line/row/subscript, into a one-dimensional array or list. I've done this before with a delimiter and then parsed it out later, but I wonder if there is a nicer way to do this?

I've done it this way before:

"John,Address1" PERSON_ARRAY(0)
"Greg,Address2" PERSON_ARRAY(1)

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?

Make A 2-dimensional Array?

Oct 10, 2009

i want to make a vb.net program that reads from a text file a movie, with the help of a Open Dialog (called openFD in my program) (we don't know how many movie we've got), the actors, the release date, the country, and the rating.

The text file look like this:

Movie1;Actor,Actor,Actor1;Date1;Country1;Rating1
Movie1;Actor,Actor,Actor1;Date2;Country2;Rating2
...

First question: How can I make a 2-dimensional array? line(0,0) - Movie1, ... , line (1,5) - Rating2. Here Is my try, but it's not good:

Dim line As ArrayList = New ArrayList()
Dim itm As ArrayList = New ArrayList()
Dim i As Integer = 0

And here is the code for the Delete Button. It deletes a movie from the listbox, but the details of the deleted movie remains for the next one, I must delete the details for the deleted movie, too.

One Dimensional Array Application

Mar 7, 2009

i'm extremely confused. my professor gave us this as the FIRST problem to do in this intro to VB class...on page 380 of our text. it is due today and i have been up all night trying to figure out where to even start. i'm so frustrated. could someone please help me and steer me in the right direction? use a one dimensional array to solve the following problem: a company pays its salespeople on a commission basis. the sales people receive $200/week, plus 9% of their gross sales for that week. for example, a salesperson who grosses $5,000 in sales in a week receives $200 plus 9% of $5,000, a total of $650. write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assuming that each salesperson's salary is truncated to an integer amount): $200-299, $300-399, $400-499, $500-599, $600-699, $700-799, $800-899, $900-999 and over $999.

Allow the user to eanter the sales for each employee in a TextBox. The user clicks the Calculate Button to calculate the person's salary. when the user is done entering this information, clicking the Show Totals Button displays how many of the salespeople earned salaries in each of the above ranges.

One-dimensional Array As An Integer?

Jul 7, 2011

I'm having trouble with this specific code and on arrays in general. This is what I am asked to do: "In this exercise, code an application that displays the number of students earning a specific score. Declare a 20-element, one-dimensional integer array named intScores with the following 20 numbers assigned to the array: (88, 72, 99, 20, 66, 95, 99, 100, 72, 88, 78, 45, 57, 89, 85, 78, 75, 88, 72, and 88). Code the procedure so that the user can enter a score from 0 to 100. Then the procedure should display using a message box the number of students who've earned that score."

First off, I do not know what I'm doing wrong with my array.. it says there's an error in line 31 saying "variable intSubscript hides a variable in an enclosing block" but I don't know what that means. And lastly, once that is sorted out, I don't know how to code a message box to appear saying how many students have received that score.

Visualize 2-dimensional Array VB?

Jun 16, 2012

I started making a very simple application where a list of names is shown in a checked-listbox. Now I would like to add a date as a second column value. This means i have two use a two-dimensional array. What containers could be suitable to visualize a 2 dim-array on a form?

I was thinking as an alternative I could keep it one dimensional and use a delimiter. Would there then be a method to format this date on the extreme right side of a listbox? I guess I would have to extract the date part, but I don't see how i could position it in a listbox.

VS 02/03 Populating 2 Dimensional Array?

Dec 17, 2010

I am trying to design a little application that allows user to enter daily attendances for 4 weeks.exercise 11, Murachs beginning vb.net) The form consists of a combo box that list the number of weeks, text boxes to enter daily attendances fro mon - fri, a button to save the entries, a button that calculates the average weekly attendance and a button to close the form.

The issue I am having is saving the user entries. I use a 2 dimensional array with 4 rows and 5 columns. Within the click event of the save button I user a for loop to loop through the array and populate each dimension depending on the week selected. Once they are saved I clear the text boxes, set the combo box index to the next position , I.E selecting the next week unless it is week 4 hence the limit has been reached. Finally move the focus to the monday text box.

When I run the code I keep end up with 2 errors depending on how i change the code. The first is that i exceeded the index of the array and the second is that "" cannot be cast to an integer. My code thus far is shown below. I have edited the data so much that I am now just confused.
