How to edit structure items on a system.collections.generic list (of )

Hi
I have a quite complex problem where I have an already populated list of a structure and I need to edit the individual items.

Here's an example of code that does not work for me:

Imports System.Collections.Generic
Public Class Form1
Private Structure myStringStructure
Dim mystr As String
End Structure
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hj As New List(Of myStringStructure)
hj.Add(New myStringStructure)
hj(0).mystr = "hmm"

End Sub
End Class

It tells me that: "Expression is a value and therefore cannot be target of an assignment."
So how do I edit the mystr of the lists entry 0. ?

Thanks in advance

Imports System.Collections.Generic
Public Class Form1
Private Structure myStringStructure
Dim mystr As String
End Structure
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hj As New List(Of myStringStructure)
Dim oNewOne As myStringStructure = new myStringStructure
oNewOne.myst = "hmmm"
hj.Add(oNewOne)
End Sub
End Class

That was exactly what I was looking for. I could have spent a lot of time trying to solve it and then it appears that the solution is so simple. I guess I just got on to structure instead of class because I'm used to VB 6.
Thanks for the solution
