View 2 RepliesVS 2010 - Most Efficient And Speedy Data Structure In Order To Carry Out Calculations
Mar 12, 2012Which is the most efficient and speedy data structure in order to carry out calculations on it?. I have seen, collections, arrays, list arrays, databases and more. I would prefer to write just straight forward code that will be effective and which I can still understand. What I would like to do initially is have the ability to add new draws to the end of the file, edit the individual files and delete lines if required.
File would then be reformatted to show the corrections made. Some kind of data entry window is envisioned. As far as number crunching goes, I would like to make counts of each number in each of the columns , calculating averages, times since last drawn and so on.
Without being too long winded, I would eventually like to find triple combinations and maybe use them as predictions. So there you have it. This way I won�t have to go off on the wrong path, on a data structure that may not be able, or be too slow for the tasks at hand.

View 1 RepliesSql Server - Store / Query Data In .NET?
Nov 23, 2011At the moment I am using Access & an OleDb connection to store data. I went down this route originally because I though that this was the best way for applications that I am distributing to my clients.
I would prefer to use something like SQL Server but is this a good idea for software I am distributing? Does the average Joe's PC have SQL Server pre-installed? If not, I suppose I can provide them with a link to download it for free?
Is there any better alternatives to Access / SQL Server?

Get Multiple Threads To Store Data In One Array?
Sep 4, 2009I have a application that use threadpool, and each thread stores data in the same textfile. I now want to have each thread store the data in the same array instead and use a timer to store all current data in the array into the text file after every couple of minutes.
So what I want to do is:
1. All threads store data in one array that they all have access to
2. After every couple of minutes the data in the array is stored into the text file.
I know number 2 can be done with a timer, but is the first one possible? If so how do I accomplish this task?

I am trying to modify the language of the program so the functions can be repeated for each unit without literally repeating each code sequence with modified variable identities. For example:

View 1 RepliesUse Data From Dataset In Calculations?
Nov 18, 2010I need a little guidance in the right direction to help with using data from a dataset in calculations. I've watched the "How Do I" Series and it was very helpful in setting up the relations and tables. I have setup a couple tables to hold values that won't
be updated and the user will never see. Lets say I have 5 columns, ColmnA to ColumnE, and the row count is variable. What I can't seem to find is an easy way to loop through using the variables. As an example, Lets say the equation would be outputted to a
textbox:
textbox1.text=row1(ColumnA*ColumnB+ColumnC^ColumnD-ColumnE)+row2(ColumnA*ColumnB+ColumnC^ColumnD-ColumnE)+etc to end of rowcount
Does anyone know if a good tutorial to point me in the right direction or a code snippet that may get me started to follow the logic? I'm using VS2010Express with a SQLExpress database if that helps.

VS 2010 - Checking Whether Two Calculations Have Same Elements
Oct 6, 2011I seem to occasionally find myself trying to compare two List(of T) to see whether or not they contain the same elements. A quick check of the documentation shows the SequenceEquals method, but that appears to check whether the two lists have the same length, and have the same elements in the same order. I don't care about the order. I want to know whether two collections have the same elements. Doing this is not terribly difficult, and seems common enough, so I was expecting that there would be some function that handles it.

This works fine but if im using lots of cells it can be quite confusing .I was wondering if there was a way that i can give a cell a unique name so i can be easy for me to identify. Using the above example it could read TOTAL = JAN TOTAL + FEB TOTAL

- The datagrid should only contain the invoices for a specific client.
- Should add up totals (Amount paid, Amount not paid, Amount Overdue, Total Amount)
- Should be withing specific date range.
Everything in this table has been saved as varchar except invoice id and unique.
VS 2010 - Need Runtime Error When Dividing By Zero In Calculations
May 12, 2011I'm trying to make a program that uses Ohms circle to calculate varying data regarding electricity, I think that if you look at my code you'll get a good idea. The problem that I'm having is that I'm using On Error Resume Next so the program will automatically find the valid calculation to calculate the value for the variable, but what's happening is that when it divides by zero (the default value for variables with no value) it gets Infinity, which it has decided IS a value, but I don't want it to be, I need a runtime error so it will bypass that calculation and go on to the next one.
