No it doesn't, if you use a general function to copy the control array
into a real array, which you can then pass to a generic function. The
trouble here will be type safety -- what type should this array be? If
it's "Control()" then you won't be able to pass it to a function that
expects RadioButton().
So you may be better off just writing your function this way:
Protected Sub DoSomething(rb As RadioButton)
// Find the index of the radio button in the same array as rb
// which is currently selected.
Dim index As Integer = -1
Dim w As Window = rb.Window
for i As Integer = 0 to w.ControlCount - 1
if w.Control(i).Name = rb.Name and _
RadioButton( w.Control(i) ).Value then
index = w.Control(i).Index
end if
next
// ...now, do something with index
End Sub
Now you can just pass in any example of that control array (including
"me" in the Action event), and it'll find the index of the one that's
selected. This works by using Control.Window to find what window it's
on, searching the controls of that window for others with the same
name, and then using their Index property to get the value of interest.
Best,
