Search And Sorting An Array?
Oct 22, 2010
I have a 2 column database....looks a little something like this:
Column A Column B
972CL 86.20716105
972CL 58.71034089
972CL 64.15368376[code].....
In column A there are 5 different variables (i have shown 3)....My goal code a macro to sort these by column A, calculate the average of the corresponding values in column B and ultimately end up with 5 variables that are the names of column A. e.g
972CL = average of all the 9721CL variables
972V = average of all the 972V variables
A caveat is that i will not know the names of the variables...i'm not sure if this code below is the right way:
For Row2 = 1 To 100
If Worksheets("Sheet2").Cells(Row2, Col2).Value = Worksheets("Sheet2").Cells(Row2 + 1, Col2 + 1).Value Then
testno = Worksheets("Sheet2").Cells(Row2, Col2).Value[code].....

I am trying to search the 4 columns of my array by using this click event. The column is determined by a radio button as you can see. I changed my code from last time and now it works, but only for the first column. If i try to search out a string in the second or third columns I get an error based on the line highlighted in blue HTML accutally shows and it is green. the error says Index was outside bounds of array
Like i said It works fine for all values in the first column, accually the second (Numbered 1). If i enter a value in the partsnumBox and it is found in the the 2nd 3rd and 4th columns I want the value in the first column (0) of the same row.

I'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.

sorting list of files in a folder. Below is a snipet of code from a program. The logic is dependant on the files coming in in alphapetical order. I did post about this earlier but I got pulled away and did not get a chance to follow the thread all the way through. The code is complete and it works. However I know it is not guarenteed to pull in alphabetical order so as my final step I wanted to sort the list of files. I thoughr using the array.sort command might work but I am not sure how to use it.
sLine = SetupNames(0)
Dim di As
New IO.DirectoryInfo(sLine)

I want to sort a decimal array (currency with the places). I'm sure that I could find a bubble sort and modify it to suit my needs but it would seem that there would be a clean solution out there so I don't have to reinvient to wheel.

I have the following code that sorts a number of names in alphabetical order(A to Z) Q,
1-How do I change it and make it from Z to A??
2-How do I cut back on the number of loops by placing -1 or whatever, because when I do that I tend to get a messy order

I am trying to sort an array of ListViewItems, here is my code for setting is up:
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Apps(), Owners() As String
Apps = {"App2", "App1", "App4", "App3", "App5"}
Owners = {"AOwner2", "BOwner1", "COwner4", "DOwner3", "Owner5"}
Dim ListViewItemArray(Apps.Count - 1) As ListViewItem
[Code] .....
I know I can have the ListView be sorted but I want the item "All" to stay at the top. I have tried sorting the array with:
vb.net
Array.Sort(ListViewItemArray)
But I get this error: "Failed to compare two elements in the array.".
I also tried:
vb.net
ListViewItemArray.Sort()
But it says there is invalid number of arguments. Is it possible to sort this array or is there an easier way to accomplish what I am trying to do?

I am trying to sort an array of processes by the process name. I fill the array by doing the following:
Dim proc() As Process = Process.GetProcesses
Then I tried doing
Array.Sort(proc)
, but that gives me an error.
I see there are a ton of overloads for the sort method, but I dont know which one will work, if any.

In the past, I have learned by reading three or four other people's coding and once I gained understanding of how it worked, I could easily write my coding. I've got I will say this is a school project, so I don't expect anyone to just throw coding at me. I'd like to actually learn this stuff! Also, I HAVE read my book (over and over) and also requested help from the instructor, but as I'd like to meet the deadline on this project, I'm having problems waiting on his availability or lack thereof.

Basically I want to find the first occurrence of one array in another. I have tried using the Array.IndexOf Function, but it always returns -1. Example:
Dim array1 As Byte() = {1, 2, 3, 4, 5}
Dim array2 As Byte() = {2, 3}
MsgBox(Array.IndexOf(array1, array2))
Even though array2 does exist in array1, the message box always shows -1
