Hello Everybody,
It is simple but I do not know why I get an error.
1. I defined a structure with 2 fields.
2. I defined a list (my_list) of that structure.
3. I Created 2 cell of the list.
When I want to change a field of second Cell of(my_list),
I get an error.
-----------------------------
Class Form1
Structure Str_Rec ' String record
Dim Str As String
Dim Loc As String
End Structure
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim my_list As New List(Of Str_Rec)
Dim Tmp As Str_Rec
Tmp.Str = "ABC"
Tmp.Loc = "1"
my_list.Add(Tmp)
Tmp.Str = "DEF"
Tmp.Loc = "2"
my_list.Add(Tmp)
my_list(1).Loc = "HHHH" ‘ DOES NOT WORK. I GET AN ERROR.
End Sub
End Class
my_list(1).Loc = "HHHH" Creates an error. Why is it, and how to overcome
The problem?
Thanks to all helpers.
