not sure if the ulong_ptr are Int32 or Int64 because if you look at the definitions they can be either depending upon how _WIN64 is defined. -Mike G

You'll need to marshal the RASDIALDLG structure typedef struct tagRASDIALDLG { IN DWORD dwSize ; IN HWND hwndOwner ; IN DWORD dwFlags ; IN LONG xDlg ; IN LONG yDlg ; IN DWORD dwSubEntry ; OUT DWORD dwError ; IN ULONG_PTR reserved ; IN ULONG_PTR reserved2 ; } RASDIALDLG; and pinvoke the call BOOL RasDialDlg ( LPTSTR lpszPhonebook  LPTSTR lpszEntry  LPTSTR lpszPhoneNumber  LPRASDIALDLG lpInfo ); My guess is that it is something like below: [StructLayout( LayoutKind .Sequential CharSet=CharSet.Unicode)] struct RASDIALDLG { int size IntPtr hwndOwner int flags Int32 xdialog Int32 ydialog int subentry ref int error IntPtr reserved IntPtr reserved2 } [DllImport(Rasdlg.dll)] public static extern bool RasDialDlg(string phonebook string entry string number RASDIALDLG lpInfo); -Mike G
