The Random generator works fine. What I have a problem with is adding the rows and columns.
Array
0,0 0,1 0,2 = row total
1,0 1,1 1,2 = row total

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 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:

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 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 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.

View 1 RepliesIm working on a roguelike console RPG. For those of you that dont know, just google search it.What I need help with is that I have an string array called ArrMap(0 to 19) that holds the 20 rows of each map for display. I also have an array of the same size called VisibleMap that needs to hold which portions of the map are visible and which arent so that when the player switches screens [IE goes from map, to inventory] they can go back to the map and it will look the same. I was thinking of using an array, but if you can think of another way to do it, that's fine.Here are the subs that deal with the map reading and display, so you know how I have things set up at the moment.
Code:
Public Sub ReadMap(ByVal location As String)
Dim ioFile As New StreamReader(location)
Dim ioLine As String

I am using Visual Studios 2008. I'm trying to make a basic addition calculator. It consists of 2 input text boxes, 1 output box and one button. Below is the code I have which works, however, instead of just displaying the answer, I want it to display the entire arithmetic problem including the answer. For example. Instead of just giving me the answer of "6" in the output text box, I want it to say "3 + 3 = 6".
Here is the code I have so far.

I have a csv file. I need to open it, delete whole row on basis of a column value, Update few of the column values and save the file as .dat file. I am using VB.net 2010
View 1 RepliesI have a data bound datagridview on my form. I need the datagridview to sort by oldest date, and then return only the 150 oldest. The goal is to export the 150 rows with the oldest date to a .csv file and then update the date column to the current date for only those 150.
Here is what I have so far:
Dim appPath As String = Path.GetDirectoryName(Application.ExecutablePath)
Dim tdate As Date
tdate = Today.Date
'sort datelastemailed by oldest to be emailed first
DataGridView1.Sort(DateLastEmailedDataGridViewTextBoxColumn,
[Code] ....
I can get it filter by the column "status" and then sort by "datelastemailed". I can also get it to export only those 150 to the .csv file. My issue is that I need only those 150 to have their date column updated to today's date and then saved to the database. The only way I can see to get that done is to set a max number of rows for my databound datagridview and then loop through each row in the date column. How I can create a filter that limits results?
I am stuck on how I go about using the nested for loops.Add code in the Draw button�s Click event to create the number of rows and columns selected, using the character selected Use nested For loops to create the rectangle of characters based on the user selections. 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.

I've populated my DataTable will all the results from a SQL search. Upon a button click I want to populate a combobox with all the results where a condition is met. My DataTable as a column called UserID and I want to add all results where the UserID is equal to a set value (for example 12). I can do this to add all results and I guess I could add a if statement inside this to be If Entry.Tag = 12 Then but is there a better way?
