[Gambas-user] how to write text in indexed list of labels

[pflora at libero.it]

Thank you to everybody.

As I am not fond in gambas language I used the solution:


Dim hlabel As Label

Dim idName as String

Dim idx as Integer

idx = ..... some integer value

idName = "Label" & idx


hlabel = Me[idName]


If hlabel <> Null Then hlabel.Text = " my string"


The above works good, I write to all 200 labels some messages indexed from UDP datagrams.
