Can someone please explain to me when I do and do not need to use the
_export keyword or a .DEF file?  I was under the impressio that normally
you export a function that Windows will be calling directly.  E.g.
MainWndProc.  Now, using the Guide to Programming GENERIC works just fine
if I have "All functions exportable" checked off with no explicit exports
anywhere.  I just use the default .DEF file.

HOWEVER....the minute I add a LoadBitmap() to MainWndProc(), it dies at
that line with a UAE.  HOWEVER....when I use Smart Callbacks, it works.


What am I doing wrong or just not understanding?

Brian
