  Just a small correction, the language you are using is no longer called Managed (Extensions to) C++, but C++/CLI.

  You need to pass the handle to the String by reference

  for the life of me i dont know how to make this work in Managed C++. what am i doing wrong ref class Test { public: static void testFunc(String^% buffer) { buffer = "altered"; } }; int main(array<System::String ^> ^args) { Test^ testClass = gcnew Test(); String^ buf = gcnew String("some string"); Console::WriteLine("before {0}", buf); //should print "some string" testClass->testFunc(buf); Console::WriteLine("after {0}", buf); //should print "altered" return 0; }

  This is similar to what you would do in ISO/IEC C++ with std::string*&
