I am using window application VS2005 to write a program. The listview will only show the data that meet the criteria set in the combobox.Is there any way to 'hide' a specific row in the listview instead of removing it? [code]
View 1 RepliesI 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.

Right now it doesn't look like it does anything. I have tried changing my index's on my subitems to 1 and 3 instead of 0 and 2 but i figured because they are subitems that they need to be subitem index 0 and subitem index 2. if that makes sense.
I have a listview control (lstBasket), and I want to only enable a button when the user selects an item.. If there is no item selected then the button (cmdRemove) is disabled.

I'm developing an application that adds .class files to a .jar using Ionic.Zip (Found Here) but this library does not support removing files from a zip, only adding them. Is there another free, open-source API that would allow me to add and remove files from an archive?
For those of you who don't know, .jar files work the same as .zip files, except their executable java files. The .jar i'm adding to and removing from, the developer said that anyone can do such things with it if they want.

What I am trying to do is remove lines of a multiline TextBox based on certain criteria, such as the number of characters or words. For example, if I paste a list of phrases into the TextBox, I want to remove all phrases that contain more than 25 characters. Once the phrases are removed, I then want to remove the empty lines that are left behind, but I have commented out the ".Replace(vbCrLf & vbCrLf, vbCrLf)" for the sake of making the results easier to follow (see screenshot from Excel below, which includes a blank cell wherever a phrase has been removed).
Here is my
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim lines() As String = TextBox1.Text.Split(vbCrLf)
[Code]....
Why is it not "blanking" the entire line in ALL cases where the line contains more than 25 characters?
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.

I am trying to search through listview in VB.net 2008. It works fine with small list, but when the list is big ( around 25000 rows), if I search multiple items , it fails saying that index is not valid. Obviously what I understand is , it it tryiong to remove an index does not exist. But I am unable to figure out where exactly it is going wrong.

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

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:

Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString
