I am able to sum an entire column and put the total in a column, but what if i want to get the average of all the numbers in the column?
Dim paxaverage As Decimal = 0.0
Function GetAverage(ByVal hope As Decimal) As Decimal
'this is where i am stuck
[Code]....
I want to include an average in a column where the average ignores zero values in a report cell where the column may have
17
19
0
[code].....
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 trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:
Dim row As New DataGridViewRow
row.CreateCells(Datagrid)
and the column using the following code:
Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)
I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:
arow.Cells("Reference").Value = Detail.Reference
However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?
well can you get the average sum of datagrid column ?
View 7 RepliesHow can I get the AVERAGE number from the column of ListView1.Items(ListView1.Items.Count - 1).SubItems.Add((reader("High").ToString) - (reader("Low").ToString)) and shows the AVERAGE number on the label.

That will be the number i would like to have it on the label.
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.
[Code]...
I put comments on the average output since I kept getting error messages about that. My out keeps saying:
Maximum value: 33
Minimum value: 33
what am I doing wrong?

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.
I need to make a difficult makro.When the makro has been activated (will happen via a button), it has to add a header and a footer to the document.Also page1/frontpage needs a different header and footer than all the other potential pages.So far, I have accomplished making page1/frontpage to work - somewhat.I did this by recording a makro, where I'd enable headers and footers, write the needed data and then stop recording.Afterwards I edited the coding so it would fit a little better. Mostly it was junk-code cleanup.

I have a global header and footer that has a Database connection and a disconnection in the header and footer and need to convert this to ASP.NET - this needs to be done before any HTML is output and after any HTML is output for the footer.I cannot seem to find any easy way to do this, like in Classic ASP - if possible post an example or link to one instead of stating a given technique.
A bit more detail is that I have an SQL Connection string then a single SQL object I want to use throughout all the pages on the website - with the connection string and declarations in the header, and the disconnection in the footer.
using asp.net/sqldatasource/vb

We are using VB 2005(Visual Basic.net) with SQL server as database and MS Access for the Reports. Right now we are passing the footer label from our VB app to MS Access for a selected report. If the user closes that report(not closing access) and opens another report the footer label is not being displayed. Is there any way I could send the footer label to all the reports in Access as soon as I open the database.Right now in below code we are sending the footer label just for the report selected. Is there a way to send the footer label to all the reports that are existing in the Access database.
Here is the code we are using right now.
Public Sub printReports(ByRef trn As ITTransaction, ByVal blnPreview As Boolean)

Dim intI As Short

I have a Gridview that I create a dynamic footer wired up to the RowDataBound event.
However there is a 50/50 chance that 3 of the columns will have no data.
I want to be able to dynamically hide the columns with no data if possible.
I have tried doing this in the RowDatabound event by checking if the value is = 0 but that does not work because I think the event is called to early?
Is there anyway to refer to the values in the Footer row after ALL the data has been bound?
Ideally in VB
`Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound

[Code]...
But this has failed (The event is never raised)..
For my project, I need to develop an app, which will have MS-SQL db with 4 tables
a>FileHeader
b>FileFooter
c>Extension
d>Detail about the file.
This is all to do with the Magic Numbers, or File header and footer, found in all files. The first 4-byte and last 4-bytes.
Example:
Suppose a word DOC file when read using this app should return and match the values
D0 CF 11 E0
So, how can I read the files using vb.net, fileIO, FileStream/StreamClass/FileReader? I just need to open the file and read the first 4 and last 4 bytes of any given file. And then it should connect back to the SQL database and lookup for the matching values from the tables as I had mentioned. And return a match found or not found.
I realise there is a solution for this but I am struggling to get it to convert to VB correctly.I have managed to get a cascading set of dropdowns with data based upon each others results which I was really pleased with.However due to the post back the grid will disappear until the second value is selected and looks awful.Is there anyway within VB to allow the header to stick around if there is no data within the grid view?
