Find The Average # Between 1-10 That Is Selected In My ListB
Jan 5, 2012
I'm having a little problem with my code as it follows, im trying to find the average # between 1-10 that is selected in my listbox but i'm having problems with my counter that divides it by, as a result i am only getting the number selected Goal is to select a value in listbox and find average based on what is selected and how many values were selected
Public Class Form1
Private Sub xRecordScoreButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xRecordScoreButton.Click
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Subject As Integer Subject = InputBox("How many products")
[code]...
Only "0" appears in the TextBox2 and not the average number.
What is the formula in VB for finding the average of two integers?I know in normal math it is e.g. (4 + 6) / 2 it only needs to be the average of two values.
i created an array of 100 cells, and the user inputs the value into them now i have to find the average of the array but not all of the cells are used how do i go to the last value, instead of the last cell? [code]
I tried the following code: Dim T5NHCEDCavg As Double qry = From employee In empList Where employee.HCEDC = False And employee.X5 = False _ Select employee.DCFSA T5NHCEDCavg = qry.Average
But I'm getting a design-time error that says "Overload resolution failed because no accessible 'Average' accepts this number of arguments." I realize that I'm missing an overload here, but I'm not sure what to use or how to do this. I'm pretty new to LINQ. I've got a dataset in memory that I'm querying, and there is a double-precision property DCFSA, of which I'm trying to get the average based on my query above.
I have a table called tblComparison - this table has the following columns[code]...
Once the averages for each column are created it needs to save them to tblMonthlyComparison - again the column names in this table are the same so in the fldDate column the program needs to enter 31/12/2011. In fldAverage of this table what we do is take the average that we found above for each column then plus them together and divide them by 5.
I am trying to make an application that would use an inputbox that will enter numbers until the user enters -1 after the numbers were entered and the user entered -1 the numbers would display within the listbox and the average would be in a label displaying "The average number is" & averagenumber in my current application I have it from 1-5 my question is how would i allow it to enter an unknown amount of numbers and create an counter for it.

I was working on some code in VB.NET 2008 and somehow got a bunch of new functions to pop up in intellisense on a datarow array. I saw find, findfirst, sort, average, and lots more. They had an icon next to them in intellisense when I saw them. Then I went and changed some of the code and now I can't get them to come back. I have used 2005 and 2003 for a long time, but still pretty new to 2008.
How can I find a listbox average removing the 2 lowest number? I tried DimintSmall AsInteger intSmall = lstGrades.Items.Item(0) ForEachItem AsIntegerInlstGrades.Items IfItem < intSmall Then intSmall = Item EndIf Next lstGrades.SelectedItem = intSmall I cant select or remove it
I am new to VB and need to make a program that does the following:Write a VB.Net program that allows users to enter a series of numbers(separated by a comma) in a text box called series. When the users clicks the command button called Average, the program extracts the number one by one from the series and calculates the average, and outputs the average onto a textbox called Result.I understand how to get it to do the average, but how can I make the program count the numbers that I input and then divided by the sum? Also, how would i get it started.
I made an application that writes to a text file in csv format, and on another tab, there is a listbox where the user can click the "View Report" button and it will display the information from the text file in a list box. Right now, I am really pleased with it because I was able to use "split" to get all of the separated values on there own individual lines.Now I am wondering, is there a way that I can display one entry at a time in the list box, and then maybe implement "previous entry" and "next entry" buttons so that the user doesn't have to scroll down through the entries to view them, they can just hit next entry and it will go to the next line in the csv text file and display the information from there? I have tried doing it a few different ways, here is what I have so far for the "View Current Report" button:
Private Sub btnViewCurrent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewCurrent.Click lblReport.Text = "Current Report"
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.
I'm working on a function to return a exponential average and there are a lot of examples of exponential moving averages but they all start with a moving average that is just the mean as a lead in to calculating the continuing moving average. I needed just a exponential average of a value set. After Googling my Bing off I still haven't seen anything so here is my attempt at a basic exponential average. Is this correct? Are there any errors? I have seen some text about adding a smoothing value to change the curve of the exponential average but not how that would be implemented.
I'm in a computer science class, and we are writing simple programs using Visual Basic 2008. I am really inept when it comes to this, as I have never done it before. I need to write a program that: "Asks the user for 5 numbers and computes the average. It then displays the average with an appropriate message before the average."
I have been really close with this, but I can't get the numbers to add up, then divide by 5, and display a pop up message.
