How do you get the "dockable" icon on forms/controls?

[TheBlindWatchmaker]

I'm working on a dockable forms/controls project. How does one get that "pin"-like icon to be displayed on a dockable MDI form / control? I'm talking about the icon immendiately to the left of the "X", in the top right corner of, say, the Soultion Explorer window, Properties window, etc.

It's a custom control. You can design one yourself or buy a look-alike from places like DivElements[^].
