Sub-Forms, like Access, in VB

Does anyone know how to create sub-forms like those
in Access using VB (code or control)?

www.21Hex.com has a control that allows you to create
window panes, which are similar to what I want to do.
You specify the hwnd of the form you want to appear as
a pane. Similarly, I was hoping to find something that
you place like a picture box and specify the form it
is to show with a simple call.

Thanks in advance.

Do you want to just simply show the form, or does the form contain controls which will be used?
