OK,

Since no one can tell me if you can have the Help Button AND Min/Max in the
control box (or why not) I'll just accept that you can't, and that I have to
use a toolbar button.

My question now is how can I get equivalent functionality from this toolbar
button? Meaning I want my button to behave as if it were the HelpButton in
the title bar: Help cursor, integration with the HelpProvider, context
sensitivity, etc.

Is this possible, and if so, how?

Keith

I remember I already explained the reasons why that's not supported.
Typically the main window has a "Help" -> "What's this help..." menu.
