I have created below code to run the python file.

When I kill the autoit execution exe in the middle of execution, it is not terminating the python.exe launched from script.

Can you suggest how to do this?

[Subz]

Have a look at OnAutoItExitRegister function in the help file.

Define Kill process?

When truly killing the process, one can't expect any cleanup, but when you "instruct" the main process to terminate itself, you could also ensure all cleanup is arranged before terminating itself.

Through this I can wireup a function to execute at the end.

But I can't kill python.exe directly in this function as it might kill other scripts running also instead of the one I invoke.

Anyother approach so that I can kill only the one I launched through my program if I click on the exit at the tray icon of the main script?

[Subz]

Can you get PID from your _ProgressRunCommand?  If so you can just kill that PID.

[ur]

_ProgressRunCommand  , I got this file from below UDF 

 

 

[Subz]

After rereading the ProcessEx UDF I realized that it uses CMD to capture the process exit codes etc..  So found an alternative by getting the before and after snapshots of python.exe in the ProcessList this should return the new python.exe as $hPID which allows you to close the process.

THank you very much.

I will try this code and let you know my inputs.

I have to ask now, is there a command to "instruct" the process to terminate itself? I've never noticed it but that would be handy indeed.

When your script has an GUI, it is easy to send a WinClose message, which then can be handled by the script as the GUI gets closed.
Another option is to monitor for a specific message and act on that.

Duh. Sorry. I was very tired when writing that stupid question that I already knew the answer to.
