There's your problem.

>SFGetFile(where," ",0L,0,'',0L,&reply);
                                ^
The SFReply you have declared is a pointer to an SFReply struct, not an
actual SFReply struct on the stack.  So, &reply means the address of the
SFReply pointer on the stack, which you haven't allocated.  What you may want
to do is change the declaration to SFReply reply, and then the SFGetFile()
call will work just fine.

Hope this helps.
