Thanks Victor, that would work if our application has to be started but the scenario is that both applications are already running.

Their custom billing application and our CRM application are both running; they want to be able to execute a command in their application (e.g. click on a link) which will open the customer account screen in our application.


>Perhaps just change your main.prg to accept a couple of parameters. If it sees parameters, then run the Cust Acc screen, if not then just run the app as normal.
