Hello from Rissia!
 What is the simpliest and the most reliable way for the application A to 
check that the application B is running and to send some information (a set 
of strigs or such) to B after? (For example: app.B is a scalable map showing 
different buildings, app.A contains the list of these buildings, the task is 
to highlight a certain building after it's name has been selected in the 
app.A.) Shall I simply declare a message and send it to the app.B? Or shall I 
use DDE?
                            Alexander
