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.
View 1 RepliesI'm coming so close to finishing this program, i want the items in my listbox to be sorted, preferably by date (the items are dates)
View 19 Repliesi 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 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 have a huge assignment tommorow in which i have to make a trivia game on visual basic. In this game you have to be able to make your own questions (modify/delete etc). Basically I have one form where you can add questions into one listbox and answers into another listbox. Now i have another form with the actual game board. I want to load each individual listbox item from the other form into the array on the game board form. Example. the first item of form2.listbox1 into question(1)
I got this so far
Private Sub Form5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim i As Integer

I've got a Program and a text file, this text file gets load into the list box but that's not the problem. The problem is that when I make the text file it makes a open line and this line gets loaded into the list box and I don't want empty items.
So here's code that I use to make text file
Public MySettingfile As String = My.Application.Info.DirectoryPath & "Process History.MemFreo" Dim myCoolWriter As New IO.StreamWriter(MySettingfile, True, System.Text.Encoding.Default)
myCoolWriter.WriteLine()
myCoolWriter.Close()
I was writing a program that would save the contents of a listbox to a database and wanted to reload the users' choices when the opened up that particular row again. My first thought was to do it with two for loops, just as I used to do in VB6, but I thought there must be a better way to do it. And there was. Sort of. It basically involves using the SelectedObjectCollection class.For this demo, you'll need a listbox called Listbox1. Set selection mode to something other than "One" or else it won't work as expected
Dim items(0 To 3) As String
items(0) = "One"
items(1) = "Two"

Ok here we go again, im a complete beginner to coding and have started with visual studio 2008 using the .net/vb libraries, as my first project i went with an emulation application, and it went great:So now i think its time to move onto a little more advanced tech's, so i added in a combo box and i want to change how my code works, and this is where my troubles are.To start of with the combo box, i have it added to my winform and have 3 items on it 'Action' 'RPG' and 'Sim' and i have made 3 .txt files in the projects root folder with the same names. What i want to have happen is when the user selects for instance 'RPG' from the combo box the items displayed in the listbox change to the contents of the rpg.txt file. After searching around for a few hours and no luck i tried this
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
If (ComboBox1.SelectedItem = "RPG") Then

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.

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...]

View 7 RepliesI have the following in my main form
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 ?
View 9 RepliesSo I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

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
It is:
1018_name1
102_name2
1026_name3
And I need it:
102_name2
1018_name1
1026_name3
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 :-

So basically I have two comboboxes. Combobox1 has these items in it:
Education and Health Services
Financial Activities
Professional and Business Services
[Code]....
I have a list of a few 1000 names, which I need to load in several comboboxes. Now I can add them manually in the editor, but then the code would be huge, which is unneeded in my hones opinion. Sure I can add then in a database and load them, but that takes more time then loading a file from the hard-drive.
