What's the best way to find a string/regex match in files recursively? (UNIX)

I have had to do this several times, usually when trying to find in what files a variable or a function is used.
I remember using xargs with grep in the past to do this, but I am wondering if there are any easier ways. | 0 | [

How to display a VRML model with .NET?

I have a request to display VRML models within a .NET application. Does someone know an easy way, maybe with standard .NET components, to achieve this? What are the issues I maybe have to face when representing VRML within an application?
