How to catch COM exception in .Net

[Franck]

Ok, I do have a COM dll written in C++. Then a web service written in C# is
referencing this COM dll. Here everything is fine.

Now I have for exemple this line in my COM, that is called from the
Webservice.
hr = pSavi->SweepFile( ..., ..., ...)

BUT, this line sometimes fails, How from my webservice can I catch the HR
result ??

Thanks for your help
