Removing Item From TimeSpan List?
Sep 26, 2010
I'm trying to remove an item from a TimeSpan list but I need a TimeSpan for the index? If I use a List(Of String) it works fine if I use an integer for the index, but if I use List(Of TimeSpan) it wants a TimeSpan for the index. I have declared a variable like so:
vb
Dim TempTime, TimeRemover As List(Of TimeSpan)
but when I try to remove an item from the timespan it says it needs a Timespan and not an integer. Say I have:
vb
For x = 0 To 3TempTime.Remove(x)Next
That doesn't work, but if I have:
vb
For x = 0 To 3TempTime.Remove(TimeRemover)Next
It will work How can I just remove an item from a TimeSpan list?
EDIT: Figured it out, RemoveAt was what I was looking for.

These two TimeSpan are stored in the Database with 24hr format. No date, only TimeSpan.
Dim r As TimeSpan
Dim tsStart As TimeSpan
Dim tsEnd As TimeSpan
[Code]...
Is there any TimeSpan method to get this right?

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

I have a requirement that regardless of the start and dates that I need to loop through that timespan and calculate figures at the month level. I cannot seem to figure it out, and maybe it is not possible, but I would like to do something like:
FOREACH Month As TimeSpan in ContractRange.Months
Do Calculations (Month.Start, Month.End)
NEXT
Is this possible or do I need to calculate the number of months, and just iterate through the amount of months and calculate the start/end of that month based on my index?

Is there a way to remove 'this' item from a collection, i.e the one I'm working with, or do I always need an index?
For each ThisItem in MyCollection
if a=true then MyCollection.Remove(ThisItem)

I have a ListView in my project that has dynamically added/edited/deleted items. When the user deletes an item, I want the item that replaces the deleted item to be highlighted. I tried simply storing the deleted item's index then highlighting the item there (list.Items(index).Selected = True). This works well unless the item deleted was the last item in the ListView (both literally and sequentially). I'm having issues today with logic and can't quite come up with code that checks for these kinds of cases.

removing the last item in the listbox which is 9.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label3.Text = ListBox1.Items.Count
[Code].....
As you can see, I set the Label3.Text = ListBox1.Items.Count and when Label3.Text = "9" I need help making it remove the 9th item.

Basically, the user can type in a name and a job description into two different txt boxes and then click add. It then adds the name to the listbox and stores it in a string list (Public strList As New List(Of String)) it also stores the job description in a string list as well (Public strListDescription As New List(Of String))Then when you select an item in the list box it knows what data to bring up in the txt boxes using an array with these lists:
Code:
Private Sub lstMyCourt_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstMyCourt.SelectedIndexChanged
Dim i As Integer

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.
[code]...
As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.
Public Class Form1
Const dcmPRICE_STRESS As Decimal = CDec(595.0)
Const dcmPRICE_TIME_MANAGMENT As Decimal = 695

I've been working on this program all week and I've been able to finally get it to work except for one problem. The program is suppose to parse strings from a text box to a list box and then from a list box to a text box using the users choice of delimiters. I can't seem to figure out how to get the last comma off the end of the list. ie cat,dog,elf,It seems it should be easy, but since I've worked on this program so long I believe I can't see the forest for the trees. I don't want for you to do my work for me.

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

I have a generic list that I'm removing items out of using List.Remove(Object). I have been removing items but whenever I get to the fifth item I'm removing it fails and does not remove it from the list. It doesn't seem to matter what I'm removing but everytime I try to remove five items it fails on the fifth item.

I am attempting to get my program to store its, in this case, a Url list in a text file. This should be relatively simple and so far it has been, writing to the document has been easy and it has all worked well, however, I have been trying to get my program to remove a url from this list too. To achieve this I have created a temporary text file, named 'FavouritesTemp.txt' and write the content of a listbox (with the target of the delete command removed from it) and then replace the old text document with the new one. But I keep getting an error from this - saying that a process is already accessing this file, even though I have just created it! I have attached a picture of my error and the code I am using underneath.
Code:
System.IO.File.Create(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt")
MsgBox("Created FavouritesTemp.txt")
Dim FavouritesWriter As New System.IO.StreamWriter(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt", True)
For Each Item In FavouritesListBox.Items

Public Structure ReportOrderType
Public ReportName As String
Public ReportDate As Date
Public SaveFile As String
End Structure
[Code] ....
Basically, I have a list of reports. In one place they get ordered, and later on the program looks to see which ones have come back -- see if the .SaveFile exists on disk. If it exists, then that report gets processed, and then I want to remove that item from the list of reports-on-order. However, I get an error message back that by doing the .Remove(R), I've changed the list itself & things won't go well with the rest of the For Each loop, which makes some sense.
When I get to this routine, the list of ordered reports will be something from a couple of dozen or less, and some number of them (perhaps zero, perhaps all, probably a few) will exist & be processed & then should be removed from the list. How should I go about accomplishing this? This is my first time working with List(of t) as a Visual Basic tool; everything I've used in the past has been with arrays, and I can do this there.
