Sorting Arrays Numerically And Alphabetically (like Windows Explorer) Without Using StrCmpLogicalW Or Shlwapi.dll - ASP.NET?
Nov 12, 2010
I created a sorter that StrCmpLogicalW / shlwapi.dll. unfortunately it causes errors on partial trust environments. I am in a really bad need of a solution that does not use 'shlwapi.dll' or StrCmpLogicalW and works in the same fashion.
Here's the sorter that causes the error.
Public Class nvSorter
Implements IComparer(Of String)
Declare Unicode Function StrCmpLogicalW Lib "shlwapi.dll" ( _
ByVal s1 As String, _

I'm killing myself and dehydrating trying to get this array to sort.I have an array containing directories generated by;Dim Folders() As String = Directory.GetDirectories(RootPath)
I need them to be sorted so they appear like in windows explorer in win7 / vista. -- numerically and alphabetically by folder names.The folder names contain both letters and numbers, sometimes letters only or numbers only.

In Visual Basic 2008 or 2010. How to sort numerically in this format:
From this:
"basketball" 900,000
"golf" 300,000
"bike" 600,000
"snow boarding" 800,000
"mountain climbing" 500,000
"roller blading" 100,000
"soccer shoes" 400,000
"football team" 700,000
"field track" 200,000
To this numerically:
"roller blading" 100,000
"field track" 200,000
"golf" 300,000
"soccer shoes" 400,000
"mountain climbing" 500,000
"bike" 600,000
"football team" 700,000
"snow boarding" 800,000
"basketball" 900,000
I would like to have a form application that I can drag n drop the words with their numbers into a Textbox1.text and have the Textbox1.text do the sorting.

I need to sort the items in a visual basic listbox numerically, that is, I have a collection of numbers I would like to be sorted increasingly.
I tried to simply use the listbox's Sorted property, but found that it treated the numbers as if they were strings, that is, it would look at the first digit, then the second, etc. to determine the order. That meant that 13 would show before 5, for example.
I thought of dumping all the numbers into an array, soring the array, and then pushing them back to the listbox, but, honestly, I don't know how to go about the sorting. I figured the array would be useless, since the listbox already acts as a pseudo array.

I've been searching for days for a solution. I've scoured the internet and other forums and tried so many things at this point that I think my brain may explode.I receive a large XML file from a third party vendor. I have converted the XML file to a a dataset and use the dataset to fill a datagridview with a specific table. I do not have a schema from the vendor and the XML file does not contain any data type information. The datagridview populates fine but all columns are defaulted to type string. This presents a problem when sorting columns that should be numeric - they sort by string comparison instead of logically numeric. I've tried numerous ways to attempt to convert the datatable columns to integer to no avail.

I have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.
DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")
All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:
9.0, 13.5, 8->13.5, 8, 9.0
But I want sort numerically, that is 8,9.0,13.5
I wonder why decimal type cannot be sorted numerically. How to achieve this?

In 2007 I created a program that reads weather data into a listview. When a user clicks on the column header it fires off the column click event handler which calls the Sort Wrapper function. The Sort wrapper will re-order items either in ascending or descending order.
I have never been able to get negative integers to sort properly. I have created a stripped down listview program with a few numbers in the grid for testing. (see attached program zip file).When you run the program, click on the column header that says "Val" and you will see right away that the numbers do not sort correctly.

I have a list of strings lets say the items are like this:
item_1
item_2
item_4
item_10
item_8
item_11
If I do list.sort() I get the following
item_1
item_10
item_11
item_2
item_4
item_8
Somehow I need to get these in order numerically but I am dealing with strings not numbers.

Example: 55, 30, 52, 23

I've got three arraylists of strings, and the "091: " part of the string is not part in the arraylist, thats added when I display them in the listboxes. So basically, how can I sort a list, and make sure that item nr 98 in english, still equals nr 98 in japanese and kanji?

I want to make a program that is similar to Windows Explorer. It will have a button that when you click it it opens a FolderBrowserDialog and it will have an area that displays the contents of the selected folder. I want to have a label that displays the current folder path (i.e. 'USERDocuments...') and I also would like a feature to search all files on the computer.Also, is it possible that when I click on a file in the contents of the selected folder it displays its information (i.e. Name, Size, etc.)? And can I also make it so that if you double click on another folder in the current folder's display it opens that folder? And can I have a button to go up one directory?

I need to know if there is any simple way to sort an array in visual Basic.net. I have been trying for some time without any real reliable results or wierd results. Here is the code this is the sort routine which transfers a csv text file read earlier into an array.
Private Sub btnSort_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSort.Click
Dim i As Integer = 2 'inner loop
Dim j As Integer 'outer loop
Dim tempstore As String = String.Empty
ProgressSort.Minimum = 0
[Code]...
The data seems to be read into the array but the sorting takes a very long time and I am not sure if it is working or not. I have read from other forums that it is easier to sort the array read from csv before splitting it. This record I am trying to sort is 250 records long. I have no idea how long that should take. Not even sure if the algorithm I chose is correct.

I have been assigned a program for homework in which I need to take in information about songs from a text file and then be able to sort the list alphabetically, by genre and by length. I also need to be able to filter it by genre. The user can then move songs they choose from the master list to a playlist where again the list can be sorted by either genre or play order.My book only covered sorting array when they are one dimensional however I need to be able to sort a multidimensional array by different columns. I asked my teacher but she had so much going on that we didn't really have time to get into it, so I decided to ask here.
I'm not looking for code, just to get pointed in the right direction. For instance rather than using a multidimensional array would it be better to pull the values in and then put them into an array of song objects with properties for each value? And if I choose to go that route is an array the best structure to use? I have to use an array of some type, but the problem says nothing about whether or not it can be a list or other array type structure.

Basically the assignment says:Create an array that accepts user input. When the user inputs -1, stop the entering process.Check user input to circumvent bad numbers (numbers less than -1)Make two copies of the array (making sure the two new arrays are only as big as the amount of numbers the user input, might need a counter)Sort the first copy using any algorithmSort the second copy using standard array.sort method.Display all three arrays in a form.I have this so far, and I'm stumped as to where to go next.

In Visual Basic 2005 is it possible to parallel sort three or maybe four arrays? I have a function that is trying to accomplish this but it only parallel sorts the second array with the Array that it is being sorted with. Here is the code
Sub ParallelListBoxSort(ByVal byList As ListBox, ByVal otherLists() As ListBox)
Dim ii As Integer = 0
Dim a As Integer = otherLists.Length
[Code]....
'listToArray' is just a function that converts a list to an 1-Dimensional array and 'setArrayToListCollection' just puts the array back into the appropriated list.

I am very confuse over a Raise Events example and using delegate as a function pointer: I am clear with this function pointer example program below which creates a generic sort function for sorting integer arrays without changing the main sort function.
' Returns True if need to swap
Delegate Function CompareFunc(ByVal x As Integer, _
ByVal y As Integer) _
As Boolean
Here are two alternative target methods for the delegate - one for an ascending sort and one for a descending sort:
Function SortAscending(ByVal x As Integer, ByVal y As Integer) As Boolean
If y < x Then
SortAscending = True
End If
End Function
Function SortDescending(ByVal x As Integer, _
ByVal y As Integer) As Boolean
