You can add packages to a project group, but whenever you activate that pacakge
to work on you will get the Package Editor to work on it.

You can do this bacsically at any stage.  If you are using an import library
(which I recommend) to tie the packageto your main project then it is loaded
early and will be available to you in your WinMain function.

You need to add the PACKAGE macro to your class declaration like

class PACKAGE TChildInPackage : public TForm
{...};

Sorry I didn't respond quicker on this, I didn't have the time until this

I'll send it to you.
