Hello,

I would like to call unmanaged code (C++ Library Code) in C# library.

When I Call C++ Function with an "int" parameter.
It seems that there is a Marshalling problem; because when I put 88 as
parameter,
My C++ function receives 1240420

How to keep same parameter value between C# code and VC++ Code ?

To explain my problem, I can send a very simple example.

When u import the function, u must know that int type in C is short in C#. And may be you have to use "ref short myvariable" if it is a pointer to int.
