The call doesn't actually change the data but if it did would I need to unbox the othingy back to the thingy if i wanted to manipulate the result.

You'd never be able to get the changes back from the call. The box gets created, a reference to it is passed, it's changed, you come back, the box goes away (no more references to it). Changes disappear. You could argue that it's prohibiting you from doing something that might be exactly what you want; I can't disagree with that. :) Brad -- Read my web log at http://www.quality.nu/dotnetguy/ You can read messages from the DOTNET archive, unsubscribe from DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com. **********************************************************************" This correspondence is for the named person's use only.
