This is more about winforms than C#, but can you answer this? I'm trying (unsuccessfully
so far) to create a dockable window in C#. Now, I can dock any type of control
I want, but I can't create the types of dockable tool windows that are in
the Visual Studio IDE. Any idea what type of control I can use to do this?
Do I use a Windows Form, a User Control, etc.?
Any help would be appreciated.

Regards.
Stephen
