Sharing data between applications (with direct application-
application communication) is a very well-worn road. And mirroring
ClientDataSets from one application to another is what the technology
called "DataSnap" (using SOAP data modules) is all about.

Delphi7 includes a unit IdHTTPWebBrokerBridge that enables an
application that has the data to become a server so as to share the
data (contained in ClientDataSets) with "client" applications.

What version of Delphi are you using?

Ian.

IAN,
Thank you very very much!!!
I use Delphi 5 thru BDS2006.
My free submarine software is educational simulation
to help children learn math and science.
