Sort Integers In A ListBox In WPF?
Oct 12, 2011
I'm trying to sort items in a ListBox in a WPF project in VB 2010. I tried searching the web but I couldn't find a code that works (maybe I'm doing something wrong). Here's what happens everytime the user clicks on the button The timer "Generator" is fired The code in Generator_Tick make 6 random numbers (no duplicates), and adds them to ListBox1 Here I want the Items in ListBox1 sorted so Every item in ListBox1 is added to TextBox1 (in the order in which they are in ListBox1)This is just a test project so I didn't give the components a name):
Here's my code:
Private Sub Generator_Tick()
Do While ListBox1.Items.Count < 6
Randomize()
Dim Combination As Integer = Int(Rnd() * 30) + 1
[code].....

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)
[code]....
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?

I need to add integers in a listbox, using for next.
Dim intCount As Integer
Dim dblTotal As Double
' here are the lines of code that will perform the calculations
' to create a grand total.
For intCount = 1 To lstCosts.Items.Count
dblTotal += dblSubTotal += intCount
Next intCount
lblTotal.Text = dblTotal.ToString("C")
The amount of items in the list box is not seso I used the items.count. I have been getting the wrong result.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
' Declarations.
Dim intCount As Integer
Dim dblTotal As Double
' here are the lines of code that will perform the calculations to create a grand total.

I am pulling data in from a query, where three of the columns are being put into the same Listbox.Does anyone know of a sort statement to sort it alphabetically after inserting the data into a listbox, or would I be better putting the results of my query into three arrays and then putting them the arrays in, in the order I want them in.

Right, I'm trying to sort a WPF listbox when a button is clicked, preferrably in pure xaml (otherwise VB). I'm having a hard time seeing as most samples are written in C#. Here's my code:
<Grid.Resources>
<CollectionViewSource x:Key="myCollectionView"
Source="{Binding Path=Query4, Source={x:Static Application.Current}}" >
<CollectionViewSource.SortDescriptions>
[Code]....
Now when this button is clicked, I'd like the listbox to sort by the field "First Name", I assume I have to change the sort description somehow? Again preferabbly in XAML, but if need be in VB could you try and keep it simple

Basically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.

How would one code a button so upon cliking it items in listbox would sort either ascending or descending (depends on the button clicked). It mustn't be done with built-in Sort() but with a for loop for example. Tried to pseudo-code the solution to the problem, went as far as "store each listbox item in an array with a for loop".

I am making some kind of calendar where I can add tasks, so I can easily organise my tasks. For it to complete, I have 3 things I can't figure out how to do it:
1. When I launch the program, I want the items in my listbox to be sorted alphabeticly.
2. I want to save the items in the listbox, so if I close the program and reopen it the items are still saved in the listbox.
3. The items in the listbox all start with a date, fe. "13-4" for today. If that date already passed I want that item to be deleted.

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.[code]
