Please see my comment to the question. Setting a "MDI container" could solve your problem. If this does not resolve your problem yet, search for the keyword MDI here:
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.aspx[
^].
This is way too simple.
Now, let's look at your problem from a different point of view: : who needs MDI, ever? Why torturing yourself and scaring off your users?
Do yourself a great favor: do not use MDI at all. You can do much easier to implement design without it, with much better quality. MDI is highly discouraged even by Microsoft, in fact, Microsoft dropped it out of WPF and will hardly support it. More importantly, you will scare off all your users if you use MDI. Just don't. I can explain what to do instead. Please see my past answers:

And read this:

Still want to do it, instead of something reasonable? :-)
