I have nine always changing values that are strings I need to know how to sort them. I have each of the nine values each on it's on panel. I want to make the panels stack highest value to lowest value. Shot of writing every possibility of combinations and let's say that would take forever.

I have created a SWAP function that does the swapping if the index value is greater than the index+1 value, with a loop that will iterate through the array (assuming that you dont have to specify how many iterations are required) until the array is sorted.
I have an array of strings such as "blue", "green", "red" and I wish to sort them so the longest string comes first and the shortest last.
Currently I am creating another array with the lengths of each string in the array in the same index positions and using this array as the key array to sort by as can be seen below, but I think this could be optimised into one line perhaps?
Dim colours() As string = {"blue", "green", "red"}
Dim colourslength() As Integer
For i As Integer = 0 To colours.Length - 1
[Code].....
Edit: just realised I defined colours as a list in the example code, it's an array in my actual code.

ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....
Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.
RollsCC.Sort(RollsCC, 0, 1)
How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.
I am using the Array type .Sort function to sort my array.By default it places the result Array into Ascending order Least to Greatest How do I change that to Descending order Greatest to Least?and How do I change it to Closest to logic? or does that not exist?Assume there is an Array of Numbers 0,13,21,-2,4,5,1.34 and I want them to sort closest to 0 or some other arbitray value; the Output should look similar to:
0,1.34,-2,4,5,13,21

This is my first time posting here although I have been lurking for quite some time. I'm stuck with a problem I have seen before and never solved: I have a long list (~23,000) of alphanumeric strings that I'm reading into a List(of String) from a text file, and then sorting. When I iterate through the list after sorting, it appears to be correctly sorted EXCEPT that the element that was originally at the beginning of the list is now at the end (and it should be somewhere in the middle after the sort)Here is a sample input:
PRE1-PRE2_00015648
PRE1-PRE2_00015649
PRE1-PRE2_00015650

I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I've been working on a small project to sort through multiple text files which have all the same strings. Basically, I am looking to sort through and create a text delimited file for future use.

Originally i wanted to ask if it's faster to sort Integers than Strings.But i have answered this question myself and i'm suprised of the big difference.Why is sorting and BinarySearch Integers as much faster compared to Strings?
The (VB.Net) Test with 1.000.000 Int32/Strings:
Private Function CheckIntBinarySearch() As TimeSpan
Dim watch As New System.Diagnostics.Stopwatch()
Dim rnd As New Random(Date.Now.Millisecond)
Dim intCol1 As New List(Of Int32)

Consider having large collections of "String-Integers"("1","2","3",...). Would it even be better to parse them to integers before sorting and searching them? What is the cost of parsing Strings to integers?

str2 = str.Split(" ")
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.
View 6 RepliesI'm using the following code to read in a highscores file with the score written first and the player's name written to the next line, and then display the top 3 scores or fewer if there aren't 3 scores written to the file. A highscores display should have the scores sorted with the highest first so that's what this program tries to implement.
Array.sort() isn't doing a damn thing. In fact, the program's not even reversing the arrays like it should either. I've tested array.sort() this way with the names and scores arrays given explicitly and it works fine. I thought maybe it was still reading the data as string even though it's declared otherwise but it rounds off decimals when I change the array type to Integer so I'm pretty sure it's not that.
I have no idea why reading the data in from a file changes how it's sorted. My teacher didn't understand what was going on either. Does anyone know what's going on here?

View 10 RepliesI need to sort an array containing a list of words and search the same using binarysearch. For certain reasons, the word-list must always be sorted using the sorting-rules of "en-US" i.e. American Regional Settings. The code will run under various international Operating Systems and of course this will mean that the word-list will be sorted differently according to the local Regional Settings in use. One problem could arise on a computer/device running with Lithuanian Regional Settings. Why? Because the letter "Y" in most languages is sorted like X-Y-Z while in Lithuanian, the sort order is I-Y-J. This behavior would create havoc to my program.
[Code]...
However, in means of flexibility I believe Guffa's answer is the best one. Why? Let's use another example:In German, the letter Ö is sorted Ö-X-Z while in Swedish and Finnish, the order is X-Z-Ö. In Estonian the sort order is Z-Ö-X. Complicated, isn't it? Guffa's solution will let me force Swedish sorting-oder (changing CultureInfo) on a device running under German Regional settings. Using Comparer.DefaultInvariant with its association to English wouldn't help in this case, probably the letter Ö would end up with O. Therefore my vote will go to Guffa.

I created this command from a few examples which reads the text from a StreamReader, Trims, splits on EoL, and returns a unique list. My next command is a sort. I couldnt figure out how to add a sort to this command. Its really not that important but I was curious if there�s an easy way.
Additionally if there's a better way to take a text file into an array or collection I'm all ears.

I have profitMarginArray(29,3) <29 is actually a variable, but figured I'd put in a number for the example> and what I need is to retreive elements 0 and 3 sorted on 3 in some way shape or form. The biggest problem is element 3 isn't unique so there could be 5 that have the same value (56.34 for instance) so a sorted list is out.
The current array could look something like
Item1, .34, .75, 54.67
Item2, .32, .75, 57.33
