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.
How would I remove files that are already added into the listview?
View 12 RepliesI've searched on the Internet and I can't find a solution to this simple problem. I've also looked on Microsoft's MUCH improved MSDN site and haven't found a solution, so here it goes. I'm trying to remove an entry from a list of class and it doesn't get removed. Here's a sample of the code I'm trying: (I renamed the class and variable names to make it a simple example)
Dim lstClass As New List(Of TheClass)
Dim mClass As TheClass
I tried this first
mClass.filename = "The Entry to Delete"

View 5 RepliesI 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 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.

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

What am I doing wrong it should just read
see if an object is already in a generic List(Of T) than the way I am currently doing it? The way I do it at the moment is like so:I have a method that I call each time I want to check to see if an object exists in the list (if it already exists I do not want to add it again) and the list to check is passed in to this method along with the item that should be added to it:
[Code]...
So as you can see this function just loops through the list that was passed in and if the DisplayName property of one of the items in the list is the same as the ProgramName argument that was passed in to the method as well then it returns True to indicate that this program is already in the list.I thought about using a Predicate with the List.Find method but cant see how I would get it to work because that predicate method will not have any way of referencing the list (its a method local list, not class level)
If I set the capacity of a List(of T) and then want to add more item will it expand automatically or will I get an Out of Bounds error?Any source of information about List(of T) out there that I can check?I am writing an application that gets a text file read into a List(of T) and then searched by the user

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.

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?

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)
