simple code problem....?

Any idea why my button1_click event handler can't access the collection I created in the form_load event? I don't know what I'm doing wrong...

Code:

---

Public Sub Form1_Load....
  Dim family As New Collection()
End Sub

Private Sub Button1_Click...
  family.Add("Tom")  ' Error: name "family" not declared!!
End Sub

---

Are you sure form load event is PUBLIC not PRIVATE?

You are declaring the family variable inside the Form_load event/sub which means it is not valid outside of that sub. So any reference to it that is after the End Sub will fail. You need to declare it in the form declarations not in an event for it to be in the right scope.

VB Code:

'inside form1 but not in any event
Dim family As New Collection()
 
Public Sub Form1_Load....
   'nothing needed here
End Sub
 
Private Sub Button1_Click...
   family.Add("Tom")
End Sub

What if the SUB is Public? still not available outside it?

No because its scope is still specific to that sub.

It seems i am confusing classes and subs.
Edit:Ok, got it! great confusion of me!

Most likely because a form is just a class. So if it is public in the class then its scope extends to anywhere in the class for that particular instance.
