INclude form form dll onto another form

[saramaia]

Hi!

I have a form that has two distinct parts. The left part are icons that represent actions (add, remove, etc).
In the right side i want to call a form from a dll i´ve developed depending on the action chosen.

Can anyone help me with this?
Is it a dll i have to develop? The one that contains the forms that i want to call from the main form???

Thanks in advance
Sara
