container for forms

hi...

is there a container in vb.net which can show forms? what i want to do is to show form_x in formMain. form_x is not always the same form...

maybe someone has an idea how to solve this problem

thanks

MDI Parents work like that, is that what you mean?

i'm searching for a control which can be placed on an existing form... during runtime the control should show different forms.

what i want to do is to design the look&feel of vb.net (especially the sourcecode-element). the opened objects (forms, classes, modules) are shown in the codearea and in the header-area the titles of the opened objects are listed. with the magiclibrary it is possible to program such an interface but the tabpage-object of the magiclibrary can only show controls (textbox...).

maybe there's an activeX-control or something like that?

userdefined controls are the solution...
