Standard Deviation Calculator - Random Number Of Numbers Input By User
Feb 19, 2011Im working on writing a program for doing standard deviation and as of right now im running into one slight issue with subtracting my mean from the original numbers. I will post most of my code so you can get an over view but i mostly just want help on this one little part for now. Im going to be making a website for school and put some programming stuff on it so i wanted to make just some random programs for it so this is school related but not really homework. It's line 26 and 27 that this is relating to. When i put a stop in my code and look at the result of arrayDifferences it gives me 0.0 when it should be -1. I know i can go this route and say arrayDifferences(1) = arrayDifferences(1) - arrayAvg but seeing as how i want this to be a random number of numbers input by the user i cant do that.

Posting Lines From A Text File (test Scores) Into An Array?
Oct 31, 2011I need assistance with posting lines from a text file (test scores) into an array. From there, I'll have to average the test scores, find the standard deviation (without using the built in function) and assign grades based on the test scores' deviation. I have already written the code for the user to search and upload a text file. And I should be able to do the standard deviation of the array, if someone can help give me an example of how to send the text file to array and average the lines of the array without using the built in math functions.

Compute Hash On Large Amount Of Data?
Jan 31, 2011I tried to follow this advice, but I still run out of memory.
[URL]
Basically, I am reading all the bytes of a 1 gb disk and I want to try and do a md5 hash on it. However, when following this example, my cryptostream gets too large a System out of memory exception.
Is there another way to do the md5 hash over some much data?
I am currently reading it into 10 million bytes arrays at a time. Can I hash the first array, and then use it as a seed for the next array, and so one, like you might do to a CRC32 calculation?
Use Data To Compute A Customers Electric Bill?
Mar 27, 2011In this program I am suppose to use data to compute a customers electric bill. My code works correctly for the most part except for two things. I cant get the loop correct I want it to ask the customer to enter readings but once it does it outputs the same information from the original time so I am wondering what I have to do to have it recalculate when new values are entered by the customer. My other issues is it is suppose to continue to ask the customer for additional readings till the value entered by the customer is -99999, when I run my program and enter -99999 it does not stop.

Standard Web Data (Access - DW CS3 - Web Form)
Jun 16, 2010I'm new but will most certainly be hanging around and maybe even answer some posts in other sections. I have the following issue: I have a vb.net web page that places data into an access database. If I leave one of the fieldS blank, (even though Access has a default value of '0' instead of null) when I click to view the results in another page, the page fails with an error.
"System.InvalidOperationException: The provider could not determine the String value. For example, the row was just created, the default for the String column was not available, and the consumer had not yet set a new String value. etc etc" IF I put any figure in the blank field, even if it's 0, the page functions and works. Baffling. So, the data input page really needs to check, 'if nothing has been entered, automatically append the database with 0. Here's some of the page code: (Standard Record Insertion Wizard within DW cs3, plus Validation)

Get The Standard BackColor Of A Standard TabPage?
Mar 11, 2009I am trying to add a TabPage containing a UserControl to a TabControl at runtime, because the number of TabPages to add are determined at runtime.
The UserControl (objDataInfo) is just two Textboxes, two labels and two Radiobuttons, nothing too exciting...
The TextBoxes have their Anchor properties set to Left, Up, Right so they scale with the width of the usercontrol.
The TabPages are added in the constructor of the form, which takes the number of tabpages to create (n) as an argument:
vb.net
Dim cList As List(Of objDataInfo)
Public Sub New(ByVal n As Integer)
[Code]....
So... How can I get the standard BackColor of a standard TabPage?
(I tried leaving out the usercontrol all-together, but the TabPage still has a gray background...)
Standard Practice For Accessing Back End Data Which Logon To Use
Feb 8, 2012What is the standard method for accessing back end data, which logon should you use? For example we have applications that require the user to login but then use an admin account to access the data from the backend.But there are also applications that require the user to login and use those credentials to access the backend data.We are in the process of creating an application that will require the user to login and would like to implement the more common method(standard practice) of accessing data.If there are alternatives those are also welcome.This will be made in ASP.Net 3.5 or higher and may include Windows Applications(VB.Net) as well.I dont want to have two sets of credentials. What I am asking is which credentials are normally used to access the Database. For example one one application may access 2 or more database's. Now would you use the same credentials they used to login to the application or would you use the admin account to access the data?Maybe this should be a seperate question but if I ended up using integrated security to access the database would the user be able to simply connect to the database using his AD account? Either through an ODBC connection and MS Access or equiv.

Save Data In A Database Table While At The Same Time Sending Standard Template Email
Jun 9, 2012I haven't done any VB coding since school (15 years ago) but currently have a need to run what "sounds" a fairly simple app at work. I'm hoping some of you might be able to give me some pointers as to whether or not my idea is possible, and if it is, how best to approach it.
I work for a company where we send a number of standard emails to potential clients asking them to contribute to our magazine . if no response we then send a number of follow up emails. each and every time I send a new email to a new prospect I'm editing one of our template emails, putting their name and email address into outlook and manually sending emails. Then for every reminder I'm going back into outlook, clicking reply all and then c&p'ing our second or third reminder emails in each and every time. needless to say at least 2-3 hours of my day are spent editing and resending the same emails on outlook.

What I want it to do is sort the scores by greatest value to least value, but the problem I'm having is that the scores are stored as strings so they are being read and sorted from left to right. My question is, how do I store the scores in a numeric array and place them in the same row as the name, but in the second column? The names and scores only need to be stored as long as the program is running so I don't want to add anything to the registry or create new files to store them.
