[DUG] progress callback

[Alister Christie]

I'm in the process of porting a desktop BDE application to a multier 
application (still using the BDE currently).  I'm using the standard 
Datasnap stuff available in Delphi to do so (remote datamodules, 
clientdatasets, providers etc...).  Some of the processes I want to 
shift into the middle tier can take minutes to process and was wondering 
how to display a progress bar while things are working in the 
background.  I presume some sort of callback procedure would be required 
so that the application can be updated from the middle tier as to the 
progress of the operation.  Can anyone point me in the right direction?
