Create An Interface Using Two-dimensional Array With 4 Rows, 5 Columns
Nov 3, 2011
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've been taking a class on it this semester and am starting to get very confused and behind. I've been pretty stuck on my hwk assignment for this week and was wondering if anyone could possibly hint at what I'm doing wrong or if I'm just completely way off. The whole rows and columns in arrays seems to be throwing me off now. Also, sorry if this is not the right place to post something like this I was not sure which section this fit under.

I am trying to create a console application that computes the row and column sum and prints the elements with the resulting sums for each row and column.[code]My column sum code is currently showing the row sums.and the rowsum code is showing a continuous sum, rather than a sum for just that row.

How do I create a multi dimensional array in visual basic. For example I have a soccer team with players. Each player has an id, first name, last name, address, phone number. How would I represent this using a multi dimensional array?

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 made a form with text boxes in a 6x6 square pattern. It will do a streamreader from a text file a number that indicates the size of the array. Then fill in the boxes with the numbers of the array. Then it will calculate the rows and columns to see if they add up to a single answer. Then it will display to an output window if it is a magic square or not. Meaning if all rows and columns add up to a single number its magic. If they dont add up to the same number then its not magic. Then it will repeat this check and output from the information of the other arrays from the text file.
I know how to code for the streamreader and get it to add the rows and columns. Im not sure about what code I need so it can check the answer if its magic or not and repeat it till the end.
Here are the contents of my text file which it will read from.

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 am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:
1) Did anything I just say make any sense ;), and
2) Can anyone help me with the code? I've got very little experience working with databases.

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 have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.

I know how to create an array and loop through it normally - but what if I need a multi-column array. e.g. usually I might do something like:
For Each row in NameofArray
Dim name as String = row
Response.Write("Hello " & name & "!")
Next
But what if I want to do something like:
For Each row in NameofArray
Dim name as String = row.name
Dim age as Integer = row.age
Response.Write("Hello " & name & "! You are " & age & " years old!"
Next
If this isn't possible with an array?

I cannot seem to figure out how to create an array that will store all three columns with the variable intProductArray as the length of the array. I have been opening the file with only one column and putting it into a textbox and using the lines of the textbox as the variable for length. I cannot figure out the array for all 3 columns.

I have a Datatable consisting of columns with Latitude and longitude I want to be able to pass through each of those values in each row into an array that can then be passed through a function which gets the distance between each row and a static. In short I am trying to get distance between one location and various others that reside in a datatable that will vary in size. Right now with this existing code I am getting 6 different locations into an array:
HTML
Public Function GetCoords() As Coord()
Dim myCoords() As Coord
myCoords(0).Lat1 = CDbl(list1_Lat.Text)
myCoords(0).Lon1 = CDbl(List1_Lon.Text)
[Code] .....
If I am on the right track I think I need to create a new array that will accept Lat and Lon from each row in my Datatable? My end goal is to be able to find properties within a certain distance of a property. In other words "return all properties that are within .25 miles of 12 Maple Street". I thought if I had Lat and Lon of a certain property there would be a formula that would give me the max and min Lat and Lon to be within a .25 mile radius. I have searched for how to get a radius, but didnt come up with anything I could comprehend. So instead I thought I would just get each properties (row) return the distance in a new column then loop through the table to return properties within the desired distance .25 miles etc...

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:

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

The outer loop will control the number of rows. Use the value selected in the Rows combo to determine the stopping value of the outer loop. Use the value selected in the Columns combo to determine the stopping value of the inner loop, which controls the number of characters per line.
