How to pass a collection of comboboxes to a Sub?

[axplains]

Hello everyone,
I would like too generate a number of comboboxes at runtime and then pass them to a Sub, like this:

For i = 0 to maxnumber
  Dim cbo As New ComboBox()
  cbo.Name = "cbo" & i
  etc...
Next
etc...
Myroutine("collection of comboboxes")

Sub Myroutine(ByVal "collection of comboboxes")
  ...do something with the comboboxes...
End Sub

What is the correct syntax to use to pass the comboboxes collection to the Sub?

Thank you.

When you are making the comboboxes add them to a List<combobox> or an array combobox[] then send that array

Tlhintoq, tThank you very much for you input, I have tried:

Dim ComboList As List(Of Combobox) = Nothing
For i etc...
Dim cbo As New ComboBox()
ComboList.Add(c bo)
Next

but I get an error "Object reference not set to an instance of an object".
There is still something I am missing...

Dim ComboList As List(Of Combobox) = Nothing

Try setting your ComboList equal to a new List(Of Combobox) instead of setting it to nothing (null)
