OK, I'm lost again... (:-/) I sort of assumed that as Icon-O-Matic created rdef files, and rdef byte arrays are used for supplying BeOS-type icon data, that to make the midi_server supply a vector icon, all I had to do was put the array from the rdef file into the message that it places in the endpoint (without the bitmap creation step) and use BIconUtils::GetVectorIcon() on that data at the other end to get a bitmap. However, GetVectorIcon just tells me that the data should be a "flat icon"! I can find nothing about converting rdef into flat icon... (Also, I see that the app icon for the server itself is just in the rdef source as "resource vector_icon array {...}" and it certainly looks as if it was created as IOM rdef output.)
