It would be great to see a snippet of how to create a toolbar. According to the SDK, I need to create an IICUIFrame, a IICustToolbar, and attach the frame to the toolbar using GETICUIFrame. I assume I get the Frame using:

IGlobal.CUIFrameMgr.GetICUIFrame("My Frame");

But am unsure of how to get a custom toolbar. I tried searching Autodesk.Max in Reflector for "GetICustToolbar" but nothing came up.
