Two OCX Questions: List And Control

[Tec-Nico]

Hello everyone!

I have two questions related to OCX development:

1.- How can I achieve a List Property like the one the ComboBoxes have? (Please check the picture)
2.- One of my events could use a Control as its parameter, just like DragOver and DragDrop do... But whenever I try to add it like this:

Public Event MyEvent(ctrlGiven As Control)

the following error raises:

"Compile error:

Private object modules cannot be used in public object modules as parameters or return types for public procedures, as public data members, or as fields of public user defined types"

So... Is there a way to pass a Control as a parameter? I mean, without doing something like this:

Public Event MyEvent(ctrlGiven As Object)

Thank you for your time!
