STL standard do not require from std::string to be refcounted. But in fact most of C++ implementations provide refcounted, copy-on-write strings, allowing you passing string by value as a primitive type. Also these implementations (at least g++) use atomic operations making these string lock-free and thread safe. Easy test shows copy-on...

In prior versions of visual studio one could specify paths for DLLs when debugging an application. I do not see a way to do this is version (2008). Is this due to the move toward deployment of apps with all DLLs, etc in the application's directory(ies)? Am I missing something, or is there no way to do this? EDIT: It was in VC6 I thi...
