Save The String Collection For A AutoCompleteHistory?
Jun 4, 2010
I'm wondering what the best method is to save the string collection for a AutoCompleteHistory
I do use the feature for Textfield and I can store the entered data in the collection, however I'm not sure how to save this string now
Code:
If Not AutoCompleteHistory.Contains(txtDeviceName.Text.Trim) Then
AutoCompleteHistory.Add(txtDeviceName.Text.Trim)
End If
Do I need to loop through the collection and write the content line by line to a file manually?

I will be doing an MVVM Project soon and I'm working a couple tutorial/examples out. How do I take the following code and connect it to a database. If I were to have a datagrid, how can I change information in the datagrid and have it automatically update? I'll be using MS SQL.

I want to retrieve the selected items in a listbox, save them to a collection, and then use that collection later. I thought that was simple enough, but when I clear the selected items in the listbox, my collections (items, indices) change. I found this out by stepping through the code.
Basically what I'm wanting to do is move items in the listbox up or down (up in this case), and still keep them selected.

I am trying to convert a collection to a string. When I am done, it should look like String() = {"File1.Tif", "File2.Tif", "File3.tif", "MergeTiffImages.Tif}. Here is what I have so far.
Dim FileArray(0) As String
Dim Count1 As Integer
Count1 = 0
For Each k In S
ReDim Preserve FileArray(Count1)
FileArray(Count1) = """" & k & """"
Count1 = Count1 + 1
Next
FileArray(Count1) = """MergedTiffFile.Tif"""
I am getting the error "Index was outside the bounds of the array." because FileArray is a string and not an array.

heres my situation and what i need done, will follow with code that sort of works
1. read a text file into a string2. for each word in string, append word to collection3. sort collection and remove duplicates4. check collection against existing collection and remove found items5 output final collection to text file
heres the code i have now, it inputs text to rich text box, replaces spaces with enter's and exports to text file, the reads file line by line to a collection and sortes and removes duplcates but takes way to long, mises words, locks up, ....it would also be helpful to remove all numbers and puntuation (anything not a-z)

I have a question. I have a class of Cars that I need to display in a simpli-ish string if they will be sold or not base on their number.
[Code]...
I'd like to display a simple string like this:Cars to be sold: 1, 3-5, 7-8, 11, which is based of the .Sell value.Is there some kind of heuristic to create this kind of string in .NET or is it just a bunch of for/each and if/then and redimming of arrays?

I'm sure you've all seen this a lot before (in a variety of forms) but I think (hope) it's a bit different. <Not actual names of variables>I have two forms (form1 and form2). Form1 has 2 class-level variables, a string (m_String) and a collection(colCollection).Inside form1, the collection is loaded using a key. With an if-statement, the collection is matched to input (from a combobox) through the matching key.The chosen string from the collection is then passed to the m_String (confirmed with MessageBox.Show(m_String)

I'm creating an open-source web browser in VB.NET Express 2008 and I've created a User Setting named History to save a collection of strings for the browsing history. However, when I try to load the history form at runtime, only the first item (of the three I added) shows up in the listbox. Below are both examples of code I have tried to use to accomplish this task.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.DataSource = My.Settings.History

I'm trying to create a favorite box in my web browser using this code in Favorites.vb
Public Class favorites
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
[Code]....
Now I have it so when you click the add button it will put the URL in the string FavList, and place the URL in Listbox1 however I have no idea how to save it, and load it.
So the next time the user opens it, it will have the URL in the string and URL box, so when they click the URL in listbox1 it will redirect the WebBrowser. I think it works like that already I just need to know how to save it, and load it.

The code below reads each line from a file and if the conditions become true it adds the contents of the file from the particular line and after into a string collection (i.e. the All contents). This is what at least what the code should do as the current one only adds the line that it encounters into the string collection.

Is it good practice to store sub-collections of item X inside a parent collection of item X for caching 'filter-queries' which are performed on the parent collection? (They won't be used together (as in color AND type).) Or is it also ok to just Loop over the collection and return the correct entities in a temporary collection?
