String Breaks To Collection?
Apr 23, 2009
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)

When it comes to storing SQL in code, most people use strings:Dim strSql As String = "Select Foo, Bar From FooBarTable Where Something = @Something"The problem is, when you have very long SQL strings, reading them in code becomes difficult. You can usually split the strings up like this:
Dim strSql As String = "Select Foo, Bar From FooBarTable " & _
"Where Something = @Something"
This causes a number of problems:

I have a WinForms app with a multi-line textbox. This displays and retains (after loading from the DB) line break characters fine. However if I assign the TextBox.Text value to a string variable and then re-assign the variable back to the TextBox.Text property, the line break characters are lost and replaced with a square character (can't past them here as they just paste as a line break!)

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.

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 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'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.
