Im writting a dll which inherits a listbox and want to access the form of the project which is using my library.

So Let's say you have a project 'bla' and a form 'form1' which uses my lib. Is there any way to acces 'form1'?

I need this, because I want to add more controls to 'form1' than just my modified listbox.

So I'm looking for something like:

```
EmmbeddingForm.Controls.Add(ButtonBla)

```

Thanks for any help!
