Sort Integers In A ListBox In WPF?
Oct 12, 2011I'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

.net - Performance-comparison Of Sort() And BinarySearch() With Integers/Strings?
Nov 15, 2010Originally 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?

View 19 RepliesRounding Whole Numbers (Integers)
Mar 17, 2010I'm a college student, working on a small project, and I'm having some trouble understanding the Round command on VB. The project is very simple and straight forward, just a simple Bail Bonds program to calculate the bail plus a 10% fee. However, i want to integrate a kind of "promotion", where for every $1000 of the bail cost, $5 would be deducted. I know the formula for this, which is reasonable simple, i just need to know how to round the Bail variable to the nearest 1000 so i can do this calculation.
View 9 RepliesDisplay All Even And Odd Integers Between 2 User Input Numbers?
Mar 23, 2009using for...next loop the program is supposed to accept 2 user inputed integers and display all even numbers between the two in one label and all odd numbers between in another label.
Private Sub displayButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles displayButton.Click
' displays the odd and even numbers between two integers
Dim intNum1 As Integer
[code]....
I'm not exactly sure what this code is doing. When I put 1 in the first number and 10 in the second number, the odd label only shows 9 and the even label only shows 10. Another example is when I put 2 and 15, the odd label comes out as 15 and the even label is 14. I'm very new to VB and programming in general and have just started getting into for...next loops and don't fully understand what the counter is or how the loop is supposed to work. I guess I'm having 2 problems. One is that I don't know how to make the program find the right numbers(my logic is off? or how I set up the loop isn't right?) and the other is the labels are showing only 1 number each instead of all the numbers in between on their own line.
Read A File As A Set Of Numbers Such As Long Integers?
Oct 31, 2009Is there a correct way of doing this in vb.net? I want to read a file as a set of numbers such as long integers ,say the file contains the string "Hello World - Its a beautiful day blah blah blah" This would read as a set of long integers that are 4 bytes long
ie ascii (hex)
48 65 6C 6C 6F 20 57 6F
H e l l o W o
etc and that would also be an 4 byte word represented as a number 1819043144 thus stepping through the file 4 bytes at a time. Instead of reading and looking for certain words in the file I would look for certain numbers, thus eliminating read errors in certain file types. I coded this type of thing in vb6 before , this would be done with the 'get' method and a file pointer. I have managed to read it a byte at a time with this code but I am unsure where to go with it as the 'get' method isn't in vb.net

Adding Integers In ListBox Using For Next?

Sum Numbers In Listbox - Add All Numbers Together And Display The Result In A Label
Jan 10, 2010I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference
LINQ - Sort By (Treat Letters As Numbers)
Sep 5, 2011How should I use linq to sort my data when my data contain both numbers and letters? For example my current linq
Dim MyQuery = From c In XDoc.Descendants() _
Where c.Attribute(Y) IsNot Nothing And c.Attribute(Str) IsNot Nothing _
Order By Val(c.Attribute(Y).Value), Val(c.Attribute(X).Value) _
Select Str = c.Attribute(Str)
Returns something like the following
13
167
172
231
44
49
Which is not what I would like it to be...
The output should be like the one below:
13
44
49
167

View 6 RepliesSort A Structure With Preserving The Position Of Similar Numbers?
Oct 28, 2010I am using structures in my programming and I sort the structure according to a value in the structure using IComparer.This is a simple example for what I want.
Dim MyArray(6) As Integer
MyArray(0) = 1
MyArray(1) = 45
[code]....
How does number 1 get sorted? Is it brings the newest 1 to top or keeps the old 1in the same index? In my original example (before sorting), MyArray(0) = 1 and after sorting MyArray(0) = 1.Is this the same original 1 or this another 1 (the newest one added to the array) moved to that position?In case the MyArray(0) = 1 after sorting should be MyArray(5) = 1 before sorting.
Here is my a sample of my Code:
Public Structure ToSolve
Dim Con(,) As Integer
Dim Discharge(,) As Double
[code]....
Using all these methods, how can I preserve the positions of similar number in the list? i.e. I want to bring the newest 'Similar' value to the top of the list.

Sort WPF ListBox On Button Click?
Apr 11, 2009Right, 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
