Can anyone give me advice on how to adapt the rigid rules of writing desk accessory software (the five procedure names must be named according to rules, etc.) to using C++ objects in the development? Has anyone had any experience? Chris Lapp Lingua Science email: Christopher_C_Lapp@cup.portal.com

You should check out my article in the October issue of d e v e l o p about
polymorphic code resources in C++. In it, I describe how to create
code resources that use virtual functions. In preparing for the article
I created several examples of this technique: an iconifiable window definition
function (object actually); a driver for interapplication communication, and
the Memory desk accessory (example included with MPW) rewritten to use a
driver object. I can make all of these examples available to the net if
there is enough interest.

And for a longer term solution, pester Apple to add an option to CFront that will emit virtual tables in a form that can reside in standalone code without requiring an A5-world. The changes required are relatively minor. Given the importance of standalone code in the Mac softwre world, it would be nice to have this support as a "standard" part of MPW C++. _____________________________________________________________________ John Miller (604) 433-1795 Symplex Systems AppleLink (rarely) SYMPLEX Burnaby, British Columbia Fax: (604) 430-8516 Canada usenet: john_miller@mindlink.uucp Macintosh Consulting and Software Development _____________________________________________________________________
