Hi Colin: Yes, I determined the same list of interfaces supported by the Explorer Band (or "Folders") band object using the OLE/COM Object Viewer. Fact is, I can host the band just fine -- it completely initializes itself and creates its HWND as expected, I just don't know how to make it do stuff. This band object supports IServiceProvider, through which you can obtain interfaces that aren't necessarily implemented by the object itself. Unfortuntately, I do not know what interfaces it can provide. It would be nice if COM allowed one to enumerate the interfaces on an object... Anyone else have input? Thanks! Nick Hodapp
