how do i do bubble sorting with numbers?
View 1 Repliesi have a few names in a list box (string). How do i use bubble sorting to sort them in alphabetical order.
View 3 Repliescan someone give a example of doing bubble sorting with numbers the simplest way if possible.all i know is that it uses a boolean to stop sorting, a variable which records how many swaps are done in a run if its 0 it stops swapping but other than that i dont know how to write a program doing bubble sorting?

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

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'm trying to implement a bubble sort on an 2 dimensional array. However the results after the bubble sort have not infact been sorted at all! I am trying to sort by the 7th item in the 2nd dimension. The other items are not important as they just contain other data but I would like to have the data kept together instead of creating another array for the bubble sort.

I've learned about and understand HOW to do a bubble sort (theoretically), but I can't seem to wrap my head around how to use a bubble sort with array structures. I'm supposed to be able to sort the inputted student information (via textfile) using bubble sort and display the result in a listbox. Buttons for Sort by last name, sort by gpa, & sort by letter grade.

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].....

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.
