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
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 = ""
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.
I have a application which processes 1000's datas.. for each processing it needs to update gui and db and many variables in my application. So what i have planned is to use 50~90 background worker with my own algorithm of thread pool, synchronization and thread close.So here is it efficient in terms of memory and performance. just confused what to use.. backgroundworker componenet or standard thread.
I have a picturebox with an image in it. I want to 'select' a section of this image (like standard selection tools in other image editors) and place it in another picturebox... The piece I want to select is a square and I have the coordinates.
I am looking to create an application that uses a remote mysql database, takes a picture from a live video stream, and also interfaces with an RS232 weighing scale. I'm just looking for a one or two sentence definition on what the huge differences are between VB Express and Standard.
I am a PHP developer and I have never worked with VB before (well maybe since high school 10 years ago). I am looking to either use vb or c++ to create this, but I have limited knowledge of any programming outside of web programming.
So, I don't want this to get into a flame war between C# and VB.NET developers. This is purely from a standpoint of a development department going forward. We've been a VB.NET company for years, but that was mainly due to who we've hired. That requirement has fallen off the wayside as of late, as we've pulled in 2 guys who specialize in C#. I used to be a C++/C# guy before converting to VB.NET for this company.
So, to everyone who has to deal with this whether on a hiring basis or a maintainability basis: how do you handle standardizing languages of choice going forward? I'm inclined to make a push for C#, as that'll make 3 solid C# developers here. But just curious what everyone's thoughts on this are.
From my application I need to run a command and parse the output. I can do this with no problem but I don't want the command to be displayed. I hoped WindowStyle = ProcessWindowStyle.Hidden would work but it doesn't. Take the sample code below for example. It works fine but the command window still visibly opens and closes very quickly and I need it to never show its ugly face. How can I fix this?

I am using a standart .net 2.0 Gridview which uses an XMLDatasource to populate the Grid. The Data property of the XMLDatasource is set dynamically which allows the gridview to change based on input.All this works fine however I am having problems with paging.I have set the AllowPaging Property to "true" and set the PageSize Property to "10". The GridView populates fine the first time around showing the first 10 records and the number of pages as hyperlinks at the bottom, BUT when i try to click on any of the page numbers to view them a message box pops up saying "Object reference not set to an instance of an object"..[code]
I am having trouble redirecting standardoutput and standarderror from a command line program that dumps a lot of numbers to the screen. I've looked through a lot of similar posts and think my code matches what it should be doing (asynchronous reading of the data with appropriate invokes for writing to the log text box) but it still just hangs the application until my p.WaitForExit times out. Once it times out and I kill the process, a chunk (but not all) of the data is written to the textbox in from the OutputDataReceived event handler. Any ideas what is going on here? I've seen some posts regarding buffer size, but that apparently is fixed (i.e. I can set a buffer size of 1 and receive every char). Below is my function to execute the process and two relevant event handlers.
Private Function ExecuteWallGen() As Boolean Dim bResult As Boolean = False Dim szExec = Me.ExecutablePath & Me.WallGenExecutable
I need to remove VB .Net Standard 2002 installation from a XP SP3 laptop I used for development. Unfortunately I threw away the installation disk which came with a VB MSPress Manual. I have read and followed the advice in KB Articles 312383, 320114 and 319714 with no success. The MSIs would not even run in admin mode. Has anyone removed this product without the installation disk? Is there a source for a detailed list of the files and folders I must manually remove?
In VS.Net 2008, if you choose a new form with the Explorer template, the form is preloaded with a menu strip, and all the items have the familar save, print, open, etc, icons/bitmaps. I would like to use these icons in other forms, but the form does not appear to reveal the location of these icons or where they came from. Does anyone know where they are? If I find them and point to them, can I be assured that these icons are in the same place on any computer (or do I need to embed them in the exe)?
i have prepared a visual basic project which is completely ready. I need to deliver it to the client in the form of an exe. , since this is my first project i do not have any idea how to prepare a standard exe.if i started to publish it says signers certificate not valid. how to rectify this problem.Im using Visual studio 2008.
I know this is a stupid question maybe, but what is the naming standard for generics?Of t or Of TEntity or Of..it doesn't really matter?I see IQueryable(Of T) but then DBSet(Of TEntity).
I am trying to redirect the output of a c program which generates output in the console. I can redirect the output once the process exits. But is there the way to redirect the output as and when there is some output in the shell window? I require this to make it understandable that the program is running and since different steps of the c code may take, say 10-15 minutes to run.
