I am involved in a project in which we want to use HyperCard as a
front end to a database and Expert System (Nextpert Object).
In the system it would be desirable to switch, under Multifinder, to
one of the other programs at the user's request. For example at a
certain point in the database it may be necessary to transfer control
to HyperCard and show a particular card/stack.
Does anybody know of a way to do this "forced" switching? LSC does it
when transferring control to it's debugger from the editor so it is
possible.
I do realize that this "feature" may not be totally in line with the
Mac Interface Guidelines, think of it as an intellectual challenge if
this upsets you!
I will appreciate any suggestions. Thanks

If it is running it will be switched to. If not, it will launch it and then switch. The only caveat to this is that it is not supported in MF 1.0, so yo might want to use the _OpenDeskAcc method if you need to be compatible with System 5.0. -Phil Goldman Apple Computer
