So, rather than wrapping individual methods, as you seem to be suggesting above, rather transfer into pure Obj-C code for the entire task of handling the open or save dialog, passing in a structure of context information if you need to do something like configure the standard dialog or filter with delegate methods.

That document is out of date. If you want to convert to 64-bit, you’ll probably need to convert to a bona-fide Cocoa application, since I believe that not only the GUI functions but the Carbon event mechanism itself is no longer supported in 64-bit. You’ll need a Cocoa run loop, and so you might as well write the whole GUI in Cocoa, and incorporate the lower-level non-GUI code from your existing code base where appropriate.
