ListBox not showing items

[koosh34]

VS2005 VB.net 2.0
I have a form called options with a ListBox1 on it, to fill the list box
from several events on the form I put the code to update the ListBox1 items
into a sub in a separate code module.

Private Sub options_Load(By Val sender As Object, ByVal e As
System.EventArg s) Handles Me.Load
updateOptionsLi stView()
End Sub

And in the seperate code module

Public Sub updateOptionsLi stView()
Dim form As New options()
form.ListBox1.I tems.Add(System .IO.Path.GetFil eNameWithoutExt ension("test"))
End Sub

If the line
"Me.ListBox1.It ems.Add(System. IO.Path.GetFile NameWithoutExte nsion("test"))"
is placed in the options_load sub it works but when I call it from the
separate code module it does not. I think this is because another instance
of the options form is being updated.
I also tried

Public Sub updateOptionsLi stView()
options.ListBox 1.Items.Add(Sys tem.IO.Path.Get FileNameWithout Extension("test "))
End Sub

But I get a warning "Reference to a non-shared member requires an object
reference" and the ListBox does not update either.
How do I get around this problem?

Re: ListBox not showing items

You may try this -

Dim frm As options
Dim fn As Form

For Each fn In My.Application. OpenForms
If TypeOf fn Is options Then
frm = DirectCast(fn, options)
frm.ListBox1.It ems.Add(System. IO.Path.GetFile NameWithoutExte nsion("test"))
frm = Nothing
End If
Next
fn = Nothing

RE: ListBox not showing items

koosh34,

One option would be to put the sub that updates the listbox in the form's
code, not a separate module.

Another option would be to send the listbox to be updated to the
subprocedure as an argument:

Public Sub updateOptionsLi stView(ByVal lb as ListBox)

lb.Items.Add(Sy stem.IO.Path.Ge tFileNameWithou tExtension("tes t"))

End Sub
