I use the following forumla to launch my PVR app to record from an XCAM2 camera when a motion detector triggers...

if(ph_getx10stat("E",4)<>2,ph_run("C:\Program Files\WinTV\WinTV2K.EXE -nss -ntod -c6 -cg -startr -qvcd -mute"),0)

Is there a way or a powerhome function that I can use to determine if the app is already running? Basically, if the app is already running, it is because someone is already watching something or recording something, so I do not want the app to be launched again ( in effect overriding the current app with a record from Channel 6 command ).

Thank you,

Robert

Robert,

Absolutely! Use the ph_findwindow function.  If the application is not already open, this function will return a 0.

You can also use the ph_switchto function to make the application the current application if it is running.  You can then use the ph_sendkeys function to actually send keystrokes to the PVR app to control it.

Hope this helps,

Dave.
