RE: MI Callback to Mapbasic from DLL - is it possible?

[Alan Hale]

Yes, this is precisely what I wish to do. In more detail, I am building a form in a 
Delphi DLL which includes a form with a listbox, to which I will pass (through a 
Mapbasic program) items derived from a MapInfo table. Each time I select an item in 
the listbox I want to pass back the item name to my Mapbasic program, and trigger a 
function/procedure to map from the item name.

It looks a s though what you and others have suggested will allow me to do what I 
require (though I'm going to have to think about it some more. Thanks very much.

If my understanding of your question is correct, you want to execute a
MapBasic function or subroutine or statements from a DLL (called itself from
an MBX).
A possibility is to use integrated mapping (via DDE or - recommended - OLE
automation).
This way you may:
- execute a single MapBasic command and run an MBX
- exchange infos (global variables) with an MBX
- send infos to an MBX, making use of its RemoteMsgHandler (or
RemoteQueryHandler); that one can parse the infos retrieved and dispatch to
an appropriate function/subroutine
