Good day.
I have a need for this type:
I have two programs Powerbuilder that must be able to call each other.
es:
The program A should be able to run the program B and open a specific window determined by the program A.
I have partially solved the problem this way:
Program A compiles some tables in the database and then makes a RUN of the program B followed by '/BATCH'.
Program B, knowing that he was call with '/BATCH', goes to read the tables in the DB and opens the window concerned.
Now comes the problem.
If program A makes another call to program B, the system should not re-open another instantaneous Program B, but must be able to understand that it is already running and open another window.
How can I make program A to understand that the program B is already in RUN and especially as I can tell it to open another window?
Ty for Help
