You have many solutions in Gambas. It depends on what you need exactly:

1) If you need to manage the events of many controls with the same event 
handlers, use the control '(Group)' property in the IDE, or give the same 
event name to all your controls if you create them by hand.

2) You can put all the controls you need in an Object[] array. This way the VB 
control arrays come back.

3) If all your controls are in the same container, you can enumerate the 
Children property of this container.

4) You can use the Tag property. In Gambas, the Tag can be what you want, not 
just a string.

5) You can use inheritance and/or composition with the native control classes.

I can't tell you precisely, as I don't know what you do exactly.
