RE: exception handling

The exception is being thrown by my code (null pointer exception or whatever). If I add a try/catch around the specific code, it gets caught as expected. However, if I let the exception propagate back to the caller of my code, the thread will be terminated.

I've seen other UI frameworks where the exception will be caught by the top level message loop within the framework, and by default logged and ignored. The user may set up a specific function to handle exceptions if the behaviour needs to be different.

What is the expected result for wx.NET?

Is the exception being thrown by your code? or code internal to the
wx.NET library?

Does it escape a blanket try/catch (general case System.Exception)?
