Stuck with String Array

[Fragma]

This has been rattling my brain for the past hour or so now so I thought I'd post here for some help.

Basically, I want it so that whenever a user hits the "add" button, the string they entered is added to an array. I want to be able to then loop through each of the strings in the array in a separate sub.

Here's what I have so far:

Public variable for array:

Code: (SELECT ALL CODE)

Dim IDS() As String

Add button:

Code: (SELECT ALL CODE)

othID = webClient.DownloadString("http://www.youtube-mp3.org/api/itemInfo/?video_id=" + getID())            
Dim int1 As Integer = urlList.Items.Count + 1            
Dim int2 As Integer = urlList.Items.Count            
Dim title As String = int1.ToString & ". " & othID.Split(Chr(34))(3)
            If urlList.Items.Count < 20 Then
                urlList.Items.Add(title)                
                IDS(int2) = getID()
            Else                
MsgBox("You have reached the 20 URL limit")            
End If

Download button:

Code: (SELECT ALL CODE)

For Each value As String In IDS                
If value.Length > 0 Then
                    othID = webClient.DownloadString("http://www.youtube-mp3.org/api/itemInfo/?video_id=" + value)                    
title = othID.Split(Chr(34))(3)                  
finID = othID.Split(Chr(34))(35)                    
download = ("http://www.youtube-mp3.org/get?video_id=" & value & "&h=" & finID)
                    dest = Application.StartupPath & "\Downloads\" & title & ".mp3"                    
webClient.DownloadFileAsync(New Uri(download), dest)                    
MessageBox.Show("Please check your application start up directory." & Chr(13) _                                  
& "File successfully downloaded into your ""Downloads"" folder")                
End If
Next

I know that I can add a number to the array like so: "Dim IDS(20) As String", however the problem is, there isn't a set number of strings for the array to hold, I just want it to hold however many items are in the urlList when the user clicks download. I can't figure out how to do this since the array is a public variable.

Hopefully this all made sense. Any help would be greatly appreciated, thanks.

I don't completely understand what you are trying to do still, but could using ReDim help?

ReDim would work, but for something like this.. I think using a list would be a better option. Review this sample code to give you an idea. If you would like a better explanation, just let me know.

Code: (SELECT ALL CODE)

Dim lstIDs As New List(Of String)
Private Sub btnTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
        lstIDs.Add("String1")
        lstIDs.Add("String2")

        For Each s As String In lstIDs
            MessageBox.Show(s)
        Next
End Sub

You're a legend thank you so much. I didn't even know you could do that.

ReDim is slow though, as KoBE shown you why wouldn't you just use a List(of String)?

I did lol... Read my post above.

I read all your posts, just saying, or you didn't know about List(of String) at the time? Or perhaps Redim?

Yeh I didn't know of either of those methods when posting the thread. I've always just used what I was before hand. :P

I'll probably be a little more active here now since I'm trying to get back into coding.

Why did you ever stop coding..? :P

Edit: Wow, I decided to go see how SF's coding section was doing... :\ Yikes.

I didn't have time for it. I don't take it seriously enough to do all of the time, it's just a hobby.
Most of my time is spent making animations, illustrations and web graphics.
But it does feel good to get back into the swing of things, even if I rarely ever finish a program lol.
And yeh, SF is near dead now. I haven't posted on there since the thread I made about Breshie's ban. Omni doesn't give a damn about that place so why should the members??
