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.
View 1 RepliesI 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 put comments on the average output since I kept getting error messages about that. My out keeps saying:

I have been trying to find the last filled column row in a sheet using this.
clast = xlapp.ActiveSheet.Cells.Find("*", SearchOrder:=XlSearchOrder.xlByColumns, SearchDirection:=XlSearchDirection.xlPrevious).Column
rlast = xlapp.ActiveSheet.Cells.Find("*", SearchOrder:=XlSearchOrder.xlByColumns, SearchDirection:=XlSearchDirection.xlPrevious).Row
Heres my code so far:
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")

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 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.
Anyone can give the coding for finding the longest & average length?(displayed in a messagebox)

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.
View 2 Repliesi am trying to get the average of an array of numbers. There could be up to 999 indexes (I picked a large array because of the the numbers of entries the array could have). As you can see I have managed to get the program to calculate the Sum of the in the array, but I am struggling with getting the average.Say, for example, I enter three sets of 90's, I get 3. How do I get an average?(BTW I have programmed it so the numbers go into an List Box, so this is why you see no code to make up the array or to where the array is printing the values).

i'm working on something to get the average color from an image and the code i have puts all the rgb values into a byte array, so the values are being stored as (r,g,b,r,g,b,r,g,b,r,g,b,r,g,b,etc). how would i loop through each r value to add them to another array to then be able to calculate the average (and so forth for g and b as well).

I'm still learning visual basic and I'm kind of stuck. I'm getting the wrong output when I test my data. I'm trying to sum array data and get an average from it. When I print out the average it's way above what it should be. When I enter these numbers 32500, 23000, 38210 I should get an average of 31236.67 but the number I get as the average is 46855.

OK, so I've been given an assignment due for Monday, which was to create a console program which allows the user to enter an unknown quantity of numbers, then have the Mean, Median and Mode averages displayed of said group of numbers.
So far I've managed to get the Mean and Median to work, for both odd and even quantities of variables. I am however stuck on getting it to calculate the modal average! I don't really know how to approach this, would a structure with two fields, variable and quantity of variable, work?
Below is the code, I haven't made it display discrete of continuous data yet, I'm leaving that for the end.

I want to include an average in a column where the average ignores zero values in a report cell where the column may have

I want 16, not 11 so (17 + 19 + 12 + 13 + 19) / 5 not (17 + 19 + 0 + 0 + 12 + 13 + 19) / 7 Something like this if it would work.
=SUM(Fields!fieldname.Value) / Count(iif(Fields!count_cycle_per_hour.Value >= 0,Fields!fieldname.Value,0))
Essentially just average everything in the column NOT a zero?

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.
