A way to launch external processes/servers during startup or later, and automatic shutdown of these processes when app exits #163
Comments
It is possible to close external processes currently, but only with some additional .bat script and WMI queries. This has been explained here: https://groups.google.com/d/msg/phpdesktop/PLC0dMz0Pp8/6kCC_VNTP_wJ Such .bat script would check whether phpdesktop.exe process still runs and when it's not running anymore it could end external processes launched by php's system() command. It's a bit complicated, but feasible. Your app's processes names shold be unique to make it reliable. Original comment by |
Related: Issue #186 ("An option in settings.json to specify a path to a script or exe that will be executed when application shuts down"). |
Somebody knows something about this feature? Is this planned to be implemented or already does? |
There is no known schedule for implementing this feature. |
This functionality can be accomplished using NirCmd command-line utility, see:

Another option is to use a script (Autohotkey or AutoIt etc) to create an app launcher. ApplicationFolder Contents of AppLauncher.ahk

A solution that worked for me is to set the port on "listen_on" option dynamically, in the first page of the app run a ".bat" file that close all process that I created before, in my case python.exe process. After this, create the process that you need. But this only works to prevent crash on re-open. Not kill all the process after close. Sorry for my bad english. |
I have pull example how to create Windows Print Service on start up and on shutdown application just feel free to take a look #305 maybe it's help you to know how it's work for me. I forgot to write settings.json value |
User can execute applications using php's system() command or similar, but there is no easy way to end long running processes when phpdesktop application closes.
Option 1 - "execute_on_startup" in settings.json
User wants to run node.js server along with phpdesktop. That server should start when phpdesktop starts and shut down automatically when phpdesktop app exits.
Solution: In settings.json add option "execute_on_startup" which would be a list of .exe, allowed would be relative paths (phpdesktop dir) or full paths.
There is also an idea for "execute_on_shutdown" option, see Issue #186.
Option 2 - new JS API: phpdesktop.LaunchProcess()
While app runs user wants to run an external process. Currently this can be done using XMLHttpRequest to a php script that calls php's system() command or similar. Unfortunately there is no easy way to end this process when phpdesktop app exits. For example this process runs a long task, but user exits application early, so this process should be killed automatically.
Solution: Add new function to JavascriptApi: LaunchProcess(). It should have some options whether the app window should be hidden. Use the ShellExecuteEx function and save process handle (SHELLEXECUTEINFO.hProcess) for later to end the process when app exits.
