I am trying to pass a callback for a Pascal (Delphi) procedure to a DLL written in 
C++ and execute the callback from the DLL.  I can't seem to keep Windows stable 
enough to track things down with TDW and I can't get a valid return value from 
MakeProcInstance for any pascal procedures.  And Delphi (as far as I can tell) does 
not allow you to export functions from within programs, only DLLs.

I've read all the FAQs I could find and reviewed all the on-line tech journals I've 
stumbled across, but no one seems to have addressed this issue.  The time of 
desperation is near...

Does anyone have an example of such a callback.  Prototypes and code examples for 
both ends would be a great help... actually at this point, any inforation would be a 
great help.

Thanks in advance.

Bob
