Some classic Windows/C++ applications can't easily be moved to managed C++.net, due to use of external libraries. Is it feasible to use newer GUI libraries like winforms (or even WPF) with such applications, 'dropping in' new controls to replace stale-looking MFC?

I have some VB.NET (which I don't normally deal with) code which must be converted to C# (which I normally do). The code happens to be in a Windows Forms app. I notice a couple of places such as: Public Sub New() ParentWindow = Me where there is no ParentWindow variable defined, and it doesn't seem to be inherited here: Public ...

I know I can scan through an enumerated list and check each window -- but that is way to intensi...
