I've been wondering about how to tie the API errors from the client DLL
together with the functional errors like the one you are confronting.
Nothing wrong happened at the API level so there isn't any ERRCODE, etc. to
report on. I think for this one you would want to hook into the OnPostError
event and handle it there.

As it is right now you need to handle these exceptions explicitely in your
application code.
