I have a routine that changes various properties of controls. Within this routine, I need to check each control that is passed into it whether or not they are contained within a control. I'm sure this can be done but I've never done it before and don't know how to check for it.

Thanks!

What issue(s) are you having with controls that are not contained by something?...we need more details to even begin to help with this one as it's too vague.

I'm trying to set the background color of a control that resides within a container control to the container control's background color.

Well, that would be difficult to do if said control doesn't have a container!  =)

You can check the Parent() property to see if it has a value.  It it is Nothing, then no container is set:
        If Not IsNothing(ctl.Parent) Then
            ' ... control has a container ...
        Else
            ' ... control does NOT have a container ...
        End If

Ok,

With the above code, how can I extract the Parent's BackColor or DefaultBackColor value?

?...Control.Parent() returns type Control.  Just access it!

Assuming it is not Nothing:
ctl.BackColor = ctl.Parent.BackColor
