I'm sorry. I still don't understand what you want answered.
Are you getting a particular exception and don't know why? If so,
please post the relevant code and the _complete_ text of the
exception, and the members here will try to figure out / explain why
it is happening.
Do you want to know which exceptions ReportDocument.Load _can_ throw,
so that you can write proper exception handlers? I can help with that:
sorry, there is no documentation. The Crystal (aka Business Objects)
documentation for the .NET API is lacking in that regard: there is no
exception documentation. All you can do is try various things and see
what exceptions you get.
Or do you want to know how to write an exception handler for a
particular exception that ReportDocument.Load throws? If so, indicate
which exception it is and what you hope to achieve in the exception
handler and we'll help you write it.
Or, perhaps, your question is something else...?
