Attached is a very simple workflow with an example. This example is
called commandLine.xml and it has a SDF directoror plus a single actor,
a 'CommandLineExec' actor. It is OS-specific in that it was set up for
Windows. If you double click on the CommandLineExec actor you will see
that the command is "/AAAA/edit0001.avi". (Note that the avi file is not
attached due to its size.) If you execute this workflow, it should use
the Windows Media Player to display the avi on the command line! (see
Note that anything that runs from the command line on your platform
should be executable with the CommandLineExec actor. You may have to
include the application name (e.g Quicktime or Windows Media Player)
followed by the file to display. Check the documentation for the ports
Of course this approach is OS specific. Details would be different
for Windows, Macs, and Linux boxes.
PS - I just noticed that running the sample on my Windows machine only
works IF I have previously displayed the avi file by double clicking on
it in the Windows Explorer (which launches the Windows Media Player) You
may have to play around with the command line expression.
