Urgent help of c++ DLL use!

hi all,
i have a c++ dll and want to use it in my c# program.

it has 7 function ,eg :

long Open(char* port)

long SetReceivedProc(void (*rp) ())

=======================================
please help me how would i declare this 2 function in my c# program?

i tried below code for "Open" function but i got this exception:
[ Could not load type 'Pos_Comunication.Form1' from assembly
'Pos_Comunication, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null' because the method 'Open' has no implementation
(no RVA). ]

-------------------------------------------------------------
[ DllImport("Pos.dll")]

public static extern int Open(string port);

----------------------------------------------------------------

So thnx for your helps :)
