My firm, an Apple Partner, is working on an image processing package which, in the manner of, say, Mathematica, permits a user to run a user interface engine on one machine and perform actual computational tasks on another machine. We wish to implement the processing server as a background-only application, but the various publications on MultiFinder don't really address certain issues in implementing such things. First: What operating system managers need to be initialized for a background-only application to operate? Are there any which need to be initialized beyond the minimum necessary to call WaitNextEvent? Second: Is calling WaitNextEvent the correct way for a background-only app to yield time to other applications? I note that the Programmer's Guide to MultiFinder claims that "background-only apps have no user interface..." does this mean that they can't receive events at all? Finally: Are there pitfalls to launching a background-only app or restrictions on its operation which would make it useless for our purpose? Can a user just double-click on a bg-only app or must it be launched by some other, regular application? If I can ever get any of this working, I will be happy to share my discoveries with anyone who's interested... Please E-mail and I will summarize for the network. -- Mark Wilkins INTERNET: wilkins@jarthur.claremont.edu AppleLink: MARK.WILKINS Programmer and Apple Technical Contact, SpectroComp Software and Consulting.
