It sounds like you're sending your data "raw". You might want to consider converting to some kind of interchange format before beaming and then parsing this interchange format on the receive side. In any case, you need to mark your data to indicate what its "type" is. This will enable you to put it in the right database on the receive side. You can do this by sending out the type at the beginning of the object, as you suggested. Or you can use a different extension and MIME type. Or you can do both of these things. Let's say I was writing a single app that combined the features of Address and Datebook, for example. I'd send out addresses in vCard format using the .vcf extension and the text/x-vCard MIME type. I'd send out events in vCalendar format using the .vcs extension and the text/x-vCalendar MIME type. I'd register to receive both extensions and both MIME types. I'd ignore the extension and MIME type on the receiving side though. Instead, I'd use the contents of the object to determine whether it's a vCard or a vCal. The first line indicates which it is; it'll either be BEGIN:VCARD or BEGIN:VCALENDAR. This is more reliable than the extension or MIME type. -- Danny @ PalmSource -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
