Create A One Dimensional Array With The Information Given?
Oct 13, 2010
I'm a beginner at programming so I'm going through the Clearly Visual Basic 2008 book. There is a problem that I'm doing called JM Sales Solution and I need to create a one dimensional array with the information given.
JM Sales employs 8 salespeople. The sales manager wants an application that allows him to enter a bonus rate. The application should use the rate, along with the 8 salespeople, in an array, to calculate each salesperson's bonus amount. The application should display each salesperson's number (1 through 8) and bonus amount. as well as the total bonus paid, in the interface.
I did the interface that's not a problem. My problem is the Create Report code. I had the program running and displaying but it didn't display all eight bonuses or the Bonus and Total Bonus paid at the end. I did some tweaking and now I can't even get it to run again. This is the code I'm currently on

I need to create a questionnaire with ten questions. The questions can be hard coded as labels. I will have a radio group box for each question, with options, Always, Usually, Sometimes, Seldom and Never. I will then need to store these values for each time that the questionnaire is answered, and another button that will show the question number and the answer count for each question up to that point in time e.g. [Code] I am also assuming I will have a button that when clicked, will identify the active radio button and add 1 to a counter?

I want to create a user defined data structure, which will be a 2 dimensional array such that each individual square of this 2-dimensional array will also store the score and the grades. ( Iam using VB.NET) More details:
for example: There is an 2 dimensional array with 3 columns and 2 rows, I want to fill each of the
(0,0);(0,1);(0,2) with their own score (Integer type) and grades (String Type).
And this is same for the rest of the squares i.e. (1,0);(1,1);(1,2) and (2,0);(2,1);(2,2)
After creating such custom data structure: "CustomArray", I should be able to create the instance of this custom data structure (which will be a class) and code something like this:
Dim objCustomArray as CustomArray
objCustomArray = New CustomArray
for i as Integer =0 to 3

I need to build an interface that allows the user to select a horse from a list. The horses are as follows: horse1, horse2, horse3 and horse4. The application should display the way the horse places with a 1 means the horse won, 2 indicates second place , 3 indicates third and 0 indicates the horse did not place. Application needs to display a summary of each horse's individual performance as well as the performances of the other horses. Table for keeping track of each horse is as follows:
5 races-how each placed
1 2 3 4 5
horse1 0 1 0 3 2

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?

I am having a problem understanding the following error message:
Value of type 1-dimensional array of string cannont be converted to 2-dimensional array of string because the array types have different numbers of dimensions This line seems to be causing the error:
New String((13) - 1) {}
I did a Google search on this but didnt come up with anything useful. I didnt even change the code.I just found this example online and copied/pasted it into a project that Im working on.

I've been working on a VB project where I use a 1st drop down list to select a movie category and then in the 2nd drop menu, movies from that category will be displayed. The movies are stored in a 2-dimensional array by category. I've been able to edit my array but I'm having problems with my .AddRange() function. What would I have to put in those parentheses for the list (for each category) to appear in my 2nd combobox when the category is selected?

For my programm I am supposed to store the minimum points in a five-element, one dimensional integer array name points. And I need to store the grades in a five-element, one dimensional string array named grades. These arrays should be parallel arrays. I am supposed to code the display grades button click event procedure so that it declares both arrays. It also should search the points array for the number of points entered by the user, and then display the corresponding grade from the grades array.
Here is my code:

Option Strict On
Option Infer Off

I have an application in VBA that gives to my VB.Net dll one bi-dimensional variant. It is a an array, in which every component is a another array containing two positions.
I want to get this two-position array. When I am using VBA I can access directly the data from each position by doing:dataArray(index, 0) or dataArray(index, 1)And when I want to get the two-position array I can use:
Dim posArray as variant
posArray = dataArray(index)

Compiling the program in Visual Basic Express produces no errors.

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()

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.

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.
