Hello In my WPF application, I want to have an "expert mode" that lets the end-user write inline python code targetting one specific control (a sheetmusic). I embed IronPython and when the user code throws an exception I catch it and display it but there are a few foolproof problems:
1) If the user write some bad code in a function and binds it to one of the control event, it will crash the whole app. Of course I can recommand my users to always wrap event handlers into a try catch block (or ask to use a decorator that do it) but it's not really foolproof. I want to make it impossible to crash the whole app with user code. Perhaps native events mecanism is a bit too low-level to be foolproof? 2) If the user code makes an infinite loop it will hang the whole app. I want to have a "panic button" to stop the script (and even restart the python engine if necessary). I suppose I have to run user code in a worker thread but then the user have to use Invoke mecanisms each time he touchs an UI object? Is there an elegant pattern that deals with this concerns? This questions are more about .NET and patterns than IronPython, but I figured some of you have already thought about it in your IP experience. Thanks for any advices! Alex
