It's really a question of how your PAR .exe was built; whether --gui was specified to pp. If your app was built as a gui, you can still launch it from a cmd prompt, but you won't see STDOUT in the console window, and you won't be able to tell that it was launched via cmd.

If you want to be able to test whether your .exe was built as a gui or a console app, this is doable. Have a look at exetype.bat supplied with ActiveState. This is actually a wrapper around a Perl script. Exetype itself only provides a setter mechanism, not a getter mechanism, but it should be easy to turn this into some code that lists out the executable type, as all the information about magic IMAGE_* structures is documented.
