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 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.
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.
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.
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, _
am havin a problem in loading sorting items in a listbox. what i want is after i load a text file into a listbox the items are compared by the last number and sorted in descending order.
i have 1 button, 1 listbox and 1 textbox.this is my code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click ListBox1.Items.Clear() Dim finish As Integer = TextBox1.Text
[code]....
if i set the sorted property of listbox1 to true that code will add 0 before the inputted number so that the sorted property in listbox1 will be usefull in sorting integers.
for example i have 1,15,30,36 it will make 001,015,030,036
thats what i think am not sure because i cant edit the code so that it will work in my program.
I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
I tried getting CodeOrder snippet working but it really messup all my tables and such when I try to add for other groups sorting first 3 works fine but when I try to add more everything gets strange. Here are my snippets: Form1.vb [URL] Form1.Designer.vb [URL]
I am using the code from hereevelopment/vbnet/code/370426 to sort my listview items. But I want something more 'dynamic': when I click on a header column, I want that it changes the sorting based on the column that has been clicked. here is my code:
I have a Windows form with a menu strip (the built-in one, nothing custom).I want to add a new list of items to one of the current menu items programmatically (no problem, done that).The new list of items I am adding is unsorted, but I want them to appear on the menu in alphabetical order.
I have a listview with items. I have a sorting class to do it. However when something is changeing my Listview control.
There are 3 colums. All items for each column exists in an struct with 3 items, one for each column. I have checked that I have all data in the array. But when I loop trough array of items and add then to the Listview, then many items in column 2 and 3 is not showing up.... This happens only after I have used the sorting class.[code...]
I used a ListBox control, and I assifned to it a list of random numbers, then I sorted the ListBox by usign ListBox1.Sort = True BUT the sorting operation is NOT right! Example of Random numbers: 1,5,7,11,12,4 After sorting: 1,11,12,4,5,7 Whixh is not right, How to make it: 1,4,5,7,11,12 Q: How to make a ListBox deal with numbers as numbers NOT as text!?
Class MainWindow Public TableDetails As New List(Of TableDetailsContainer(Of TableXDetails)) Public Sub ArrangeByID() '''STUCK HERE''''
[code].....
What I basically want to achieve is to sort TableDetails(i) items by their "ID", but I have absolutely no idea how to go about it. Could anyone please give me pointers?Also, I actually want to move the columns within TableDetails(i) around, manually. But I'm not too sure how to do that.
I have created a program that when a user selects a button, an input box is displayed to type in, for instance a name, when clicked ''OK'' the name goes into a textbox, how can i program it so that the contents of that textbox is automatically sorted into Alphabetical order according to the first to the first letter ?
I have problem with Sorting ListBox in Visual Basic 2008. When I load names from some files (file's name is number_name like="156_blabla") and I need sort it by that number
I am trying to sort text (File name and path), by having a listbox with just file name and and a datagridview with two columns filename and path.
The listbox sorts it differently from the datagridview. Mainly this is where there is a ' ie listbox puts "you're" before "you are" where the datagridview puts "you are" before "you're".
I thought I would just sort using datagridview and then read from datagrid and add to a non sorting listbox, but this did not work although the datagridview shows sorted, when you go through and a loop, reading each row to add to listbox they end up the same order they where originally put into the datagridview befrore sorting.
What I want is a sorted list of file names only, which will be obtained from several folders and then when clicked with be able to extract the complete path and filename.
I have code with a listbox and datagridview which works ok if I remove any files with ' in them.
I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.The code that I am using for the Device response capture, etc is :-
*********Code Start Private Sub btnPoll_Click(ByVal sender As System.Object, ByVal e As_ System.EventArgs) Handles btnPoll.Click
sort the listbox that is being populated by data from an exteranl hard drive. The DB's on the Hard drive are contained in folders with a naming format as follows (Jan94 - Dec08)The issue is that on the HD all the folders(yrs) for Apr are listed together and then the rest listed the same way, just sorted based on 1st alpha character. The format I want to show in the list box is as follows:
I am using the below code to find all the items in a listbox using vb.net 2005. But how can remove the non searched items from the listbox after searching?
probs a simple answer but my mind is blank atm. I have this code to move all items from listbox3 to listbox1 but it wont move them unless i select 1, then it moves all items.
