using a c++ library from c#

Hi It is possible to use c++ (native) librarys with c#. There are two possible ways. a.) Use MC++ wich allows to mix managed and unmanaged (native) c++ code. b.) Use P/Invoke (Platform Invokation Service). -> Example for solution b.): using System.Runtime.InteropServices; internal class Win32 { [DllImport("kernel32.dll", SetLastError=true)] internal static extern IntPtr CreateFile(String lpFileName, UInt32 dwDesiredAccess, UInt32 dwShareMode, IntPtr lpSecurityAttributes, UInt32 dwCreationDisposition, UInt32 dwFlagsAndAttributes, IntPtr hTemplateFile); } Simon
