Interrupting execution of PyRun_SimpleScript()
Hi,
Im am using PyRun_SimpleString() inside a BCB 5.0 GUI app
on win32.
All works fine.
The PyRun_SimpleStript() runs a piece of python
code which calls often a callback function to
refresh my gui App so my Form still can react
to user input.
Now, I would like to implement a possibility
to interrupt the execution.
For this I have a button called "stop", and when
the user executes it, I generate an exeption by
calling:
PyRun_SimpleString("raise KeyboardInterrupt\n").
I see in the window where I redirected stderr and stdout
the exception, but the original code (a for loop)
still continues to run.
Does there somebody have some idea (in the Python FAQ
i didnT find anything)
Thanks
Anton

Never used it so can only offer a suggestion.

The fact that your GUI can call SimpleString implies
to me that Python is running with multiple threads.
The string is executed in a different thread from your
other thread. The exception isn't being called from
the right thread. Instead it's caught by the top-level
exception handler for the GUI, which reports the error.
Is it possible to put an explicit "check this variable
and if it's true then abort" in your time-intensive code?
