[VB] Linked List question - Tilted Forum Project Discussion Community

I doubt that's the correct wording for it. I'm used to C, not VB. Anyway, I'm trying to make multiple instances of a something so that I can easily edit them, then I want to write it to a file. My problem right now is, I don't know how to make a list like that or if it's possible. Thanks.

If you know how many items you will need, you could put them into an array instead of a linked list.

You don't need to know the length of the array. You can Redim preserve the array to make it longer.
something like this:

Code:

Public Class Form1
    Inherits System.Windows.Forms.Form
    Dim YourArray() As YourClass

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        '...
        'your code here
        '...
        PutInArray(YourInstance)
        '...
        WriteToFile(YourArray)
    End Sub
    Sub PutInArray(ByVal sYourInstance As YourClass)
        ReDim Preserve MyArray(YourArray.Length + 1)
        YourArray(YourArray.Length) = sYourInstance
    End Sub
    Sub WriteToFile(ByRef sYourArray As YourClass)
        Dim i As Integer
        'your file open code here
        For i = 0 To UBound(sYourArray)
            '...
            'your file write code here
            '...
        Next
        'your file close code here
    End Sub
End Class

An example of the list that I'm using is:
Mob
char Name;
char longname;
char short;
int level;

and a bunch more after it. In all I think there are about 25 values that are needed.
There could be at least 1000 instances of each list.
