I found on p. 10 of the iPhone user guide under Website Install that I could use "handbase://mydomain.com/mydata.pdb" to access database mydata on mydomain.com. A number of app launchers on the iPhone allow using the URL scheme to start an app, e.g., Launch Center (more info at http://appcubby.com/urls/ or http://wiki.akosma.com/IPhone_URL_Schemes). When I create an entry in Launch Center using handbase:// with or without a database, HanDBase opens with an error message or two. I have multiple databases on my iPhone and I'd like to set up 2 entries in Launch Center to access the 2 databases I use most frequently. What's the syntax for starting HanDBase and automatically opening a database that already exists on the iPhone?
