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
