VB-Managed C++ Dll

1
I'm using a Managed C++ dll called froma a VB program.

I'm trying to use argument by ref in the Dll functions, but in the Dll manifest the functions still appear with arguments by val.

I use this definition:

bool MyFunction(String ^param1, Int32 ^param2)

and it doesnt work

How can I pass a parameter by ref using vb.net and a C++ managed dll?

Thank you all
