How will i compute Standard Deviation in LINQ? How do i convert Average in decimal in LINQ? I'm working on the code below. I already got the Average but it's in whole value not decimal. I need a four point decimal for my Average. Help please.
Private Sub Compute_VIT_MeanSD()
Dim decAverage As Decimal
Dim msg As String = ""
I seem to figure out why my code is not for finding mean and st dev because the code i wrote for finding the sum is working and mean = sum/N so im confused i think i might have the wrong formula/code for standard deviation tho..i just found it online..
Private Sub btnDisplayMean_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayMean.Click Dim Mean As Integer Dim Sum As Integer For J = 0 To MyArray.Count - 1
Im 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.
I build program to launch application(launch application can as local profile or can as network credentials) using Advapi32 "Create Process WithLogonW".but I got the problem, I can't capture message of standard output(Stdout) and Standard Error(stderr).could everyone help me how to capture message and the code?
I usually use standard button and do the settings like causevalidation etc if required.
i decided to use toolstrip and inserted some buttons but end up that it doesn't do the validation for control and also doesn't call leave event of textbox control.
so my question is, anyway to use regular button functionality for toolstripbutton or there is a way to add regular button on toolstrip.
Currently i am able to compute MI (Maintainability Index) at a VB Method and VB Function Level. I would like to know how this can be rolled up to the application level?
I have a Database named CarsType.accdb there are four fields in the data base Item_Name, Item_Num, Item_Qty, Item_Cost.
I am able to get the database to display my data in VisualBasic but I am not sure how to get the total cost to appear in my label (lblTotalCost). I prefer doing it in VB versus writing in my access program. All I am wanting to do it multiply item_qty * Item_Cost How would I go about doing that?[code]...
I need to round the result from compute.8/19, how can i round this result to two decimal.Is there any symbol i can use for compute function to recognize the rounding format, because not must be two decimal,sometime may one or in integer?
I've created a DataSet with DataTable and I'm adding values of DataRow - Zvodp [m] in a For loop. Data type of this column is Double. When I want to use Compute method like this:
In fact i want to list in grid the table A with a column which contains a checkbox and is checked if the item is include in table B (field TableA_Id_A).
how to code the automatic compute the date. Example In Date Applied the Date today February 18, 2012 then will be automtic compute in 10 days in Date Realesed February 28, 2012.i have code for the date this is for the DateApplied: Label26.Text = Format(Now, "MMMM dd, yyyy")
My assignment is to compute commission for a stockbroker within the following parameters: Commission for stock =< $50.00 = 0.19 base per share; for stock >$50.00 = 0.26 base per share If number of shares is =< 150 then commission rate is 1.5 * base per share. [code] Did I mention that I am an extremely new user to VB?
ei guys how to compute values in a datagrid column.. we have just tried some codes but it appers false anyway.. just need it badly.. i just have 30 min. :CCC
What i'm trying to do is compute whether an integer number is prime or not. The program performs this analysis for all odd numbers from 3 up to an input integer limit, for example 100. If the integer in the range 3 to limit is prime, a message stating so is printed. Otherwise, a message is printed that lists at least one other integer divisor. The output for each analyzed number consumes one line of text.
A sample output is shown below:
Limit is 100: Number 3: is prime Number 5: is prime Number 7: is prime
[CODE]...
I understand I need to use loops, boolean functions, vbmath(), strings and multi-line out via concatenation. So I can put this is words how I think it should be done but not so great putting the code together
Test all integers up to the SQRT of the number (100)
limit = math.sqrt(100) + 1
Followed by 1 For statement For c = 0 to 100 step 2? And an If statement If ...... result = false
i have a problem regarding my project, its a library system to be exact here the flow of the problem in the library there is a borrowing time and a returning time of books every hours that the student failed to return the book it will cost 5 pesos(philippine money)and in a day it will cost 40 pesos.. 9 am to 5 pm is the counted hours of penalty, night is not included in the computation of penalty.. my borrowing form is in datagrid view.. is it good to do this in details view how to compute in date and time format?
this function enables you to calculate a full arithmetic calculation , as 5*(3+2)+6 , but : it's limited with (+,-,*,/) signs . is there any way to add a support for the another signs (like : !,sin,cos,tan,root,^,log and another signs) to give the user the ability to calculate a full calculation including the other signs which cannot be calculated within the compute.datatable function ?
I am using xml reader to read an xml file into a dataset and and then create some dataviews and bindingsources for binding combo and text boxes as such:
Dim folderName As String Dim xmlFile As XmlReader Dim ds As New DataSet()

I don't know how to do the same thing I am trying something like:
I have this code to compute average and stored the result in textbox3.[code]In label6 I want to store the result (2+3+5/3=3.33 so in label 6 will be displayed the result 3.33 and in label 7 will be displayed the result 3 because it rounds my result from label6.
I tried to follow this advice, but I still run out of memory.

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?
