Array.Sort(array) - Specify A Numeral Sort Based On The First Character In The String?

Jan 29, 2009

Sub Sort()
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.

Using The Array Type .Sort Function To Sort An Array?

Mar 1, 2010

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

.net - Array.Sort() Doesn't Correctly Order Target Array

Apr 13, 2012

I'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?

Imports System.IO
Public Class Form2
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Plotting An Array Of Points On Button Click

May 9, 2011

I have an global array of points that i want to plot in VB. say X and Y points, and typically they have values of +/-12000. Now I've not done graphics work for a long time and when I did, I used OpenGL with C. Now I need a GUI i'm using VB 2008. Firstly, what's the best method of rendering the array of points? should I use some port of OpenGL? GDI? or what?

Secondly, can I simply print to perhaps a Panel on hit of a button? Thirdly, do I have to place any line drwing code in an "OnPaint" event handler? Finally (for now) if my array represents points in a space much larger than the painting surface, how would I scale and scroll the final image within the the proposed Panel? I look forward to your advice.

VS 2010 Using Array Of Points With E.Graphics.DrawLines

Apr 30, 2010

I've rewritten my program so it would be more .net friendly (meaning I try to draw in picturebox.Paint event).

I try to use DrawLines using array of points, which are added by user one by one, but I can't figure out how to force my program to only use points that have been set by user and not the whole array.

When I call DrawLines pointing at my array of eg. 10 points and only 5 had been set, I end up with a nice set of lines with the last going to the upper left corner (0,0) and supposedly staying there for 4 more points, which is unacceptable.

I think of using ReDim Preserve each time, but I am not sure if it is the most efficient way to do this.

Anyone can think of something more elegant before I implement this redim monstrosity?

C# - .net - Array.Sort And Array.BinarySearch - Culture And Globalization?

Apr 19, 2009

I 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.

Add Data Points From Double() Array To Existing Chart Series?

Jun 21, 2012

I have an array of type Double() (1 x n) that I am trying to quickly plot on a graph I've already set up. The only thing I want/need to do is take my array and store it as data points (y-axis values) in the series I already have. What's the best way to do this? Also, will the data points that are plotted change as my array changes, and if not, how would I replot those new points and get rid of the old points?

Add An Array Sort Inline?

May 6, 2012

strtest() = objFile.ReadToEnd.Trim.Replace(vbCr, "").Split(vbLf).Distinct.ToArray

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.

Sort A Multidimensional Array?

Sep 23, 2011

vb.net 2005.

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
Item3, .29, .5, 42

Sort A Multidimensional Array By The 3rd Column?

Oct 3, 2009

Dim array1(9,2) as String

So basically, 10 rows and 3 columns and say I want to sort them by the values in the 3rd column.

Each row is essentially a record of data and must be kept together.

Now I know that you can't use the array.sort method but would I have to use a bubble sort or something for this?

What's a good way to manipulate the records while still keeping each row linked together somehow.

Sort An Array And Remove Duplicates?

Sep 8, 2009

I have a semicolon delimited string (e.g. an EMail Address List returned from a database or a textbox). How do I separate the string into an array, sort, and remove duplicates? The code below works to separate the string and sort the results, but doesn't remove the duplicates. I could probably then loop through the array and copy to a new array to eliminate the duplicates, but there must be a better way to do this using the VB.Net Array, String, and Collections handling classes.

Sort Array Of Strings By Their Lengths?

Apr 4, 2012

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.
