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]

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?
How do I go about removing specific instances from a string. For example, I've got this string [32m50[0m/[33m2[0m/[31m2[0m and I want it to reads as 50/2/2 by removing instances of [31m, [32m, [33m, and [0m

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.

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.

View 5 RepliesI was generously guided by the community to use LINQ to find duplicates on my listboxes the last time around. However, I am now in a tough spot because I need to find and remove duplicates from a multicolumn list view. I tried using LINQ but it says that the listview object is not "queryable". Is there a way for me to find and remove duplicates using only one column of the listview? [code]The code now runs fine when I call it. But it does not remove the duplicates:

how to hide Listview rows ?
I want to disable or hide a specified listview item in ListView control, how to do?
View 10 RepliesI have a listview control on a form. This listview control is populated with at times thousands of listviewitems.Part of my process, is running through custom made filters, to hide unwanted items (before they're even inserted into the listview).So as I hinted earlier, the way I hide items that I don't want is by not inserting them at all. I'd like to make a shortcut available, that would allow me to show / hide the hidden items by simply pressing the shortcut.
My problem is that if I do this, I have to 'refresh' the listview items everytime as I do now ( by removing all and re-inserting the ones I want ).Is there no faster / better way than by removing / re-inserting the items ( which takes roughly 2-3 seconds ); which is a noticeable-enough delay? for a 'visible' property on the listviewitem that I could set to true / false, but that property doesn't appear to exist.As it stands, I have to resort to removing / re-inserting the new 'view' every time.
I have a listview in details mode with multiple columns. I want to be able to temporarily hide entries. I know the old Listview.Items(x).hide = true doesn't exist (from research).I'm wondering if there's a way to create a temporary list of every item NOT to display, remove them from the listview, then when I want them back, just re add them from the list
