@msdn=http://search.microsoft.com/search/results.aspx?qu=$$$ @pinvoke=http://pinvoke.net/$$$.htm Summary: The NCB structure represents a network control block. It contains information about the command to perform, an optional post routine, an optional event handle, and a pointer to a buffer that is used for messages or other data. A pointer to this structure is passed to the (NetBIOS) function !!!!C# Definition: public static const int NCBNAMSZ=16; [StructLayout(LayoutKind.Sequential, CharSet=CharSet.Ansi)] public struct NCB { byte ncb_command; byte ncb_retcode; byte ncb_lsn; byte ncb_num; IntPtr ncb_buffer; short ncb_length; [MarshalAs(UnmanagedType.ByValTStr, SizeConst=NetbiosConstants.NCBNAMSZ)] String ncb_callname; [MarshalAs(UnmanagedType.ByValTStr, SizeConst=NetbiosConstants.NCBNAMSZ)] String ncb_name; byte ncb_rto; byte ncb_sto; IntPtr ncb_post; byte ncb_lana_num; byte ncb_cmd_cplt; [MarshalAs(UnmanagedType.ByValArray, SizeConst=10)] byte[] ncb_reserve; IntPtr ncb_event; } !!!!VB Definition: Private Const NCBNAMSZ As Integer = 16 <StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Ansi)> _ Private Structure NCB Dim ncb_command As Byte Dim ncb_retcode As Byte Dim ncb_lsn As Byte Dim ncb_num As Byte Dim ncb_buffer As IntPtr Dim ncb_length As Short <MarshalAs(UnmanagedType.ByValTStr, SizeConst:=NCBNAMSZ)> Dim ncb_callname As String <MarshalAs(UnmanagedType.ByValTStr, SizeConst:=NCBNAMSZ)> Dim ncb_name As String Dim ncb_rto As Byte Dim ncb_sto As Byte Dim ncb_post As IntPtr Dim ncb_lana_num As Byte Dim ncb_cmd_cplt As Byte <MarshalAs(UnmanagedType.ByValArray, SizeConst:=10)> Dim ncb_reserve() As Byte Dim ncb_event As IntPtr End Structure !!!!User-Defined Field Types: None. !!!!Notes: '''Considered Obsolete''' Typedef struct _NCB { UCHAR ncb_command; /* command code */ UCHAR ncb_retcode; /* return code */ UCHAR ncb_lsn; /* local session number */ UCHAR ncb_num; /* number of our network name */ PUCHAR ncb_buffer; /* address of message buffer */ WORD ncb_length; /* size of message buffer */ UCHAR ncb_callname[NCBNAMSZ]; /* blank-padded name of remote */ UCHAR ncb_name[NCBNAMSZ]; /* our blank-padded netname */ UCHAR ncb_rto; /* rcv timeout/retry count */ UCHAR ncb_sto; /* send timeout/sys timeout */ void (CALLBACK *ncb_post)( struct _NCB * ); /* POST routine address */ UCHAR ncb_lana_num; /* lana (adapter) number */ UCHAR ncb_cmd_cplt; /* 0xff => commmand pending */ #ifdef _WIN64 UCHAR ncb_reserve[18]; /* reserved, used by BIOS */ #else UCHAR ncb_reserve[10]; /* reserved, used by BIOS */ #End If HANDLE ncb_event; /* HANDLE to Win32 event which */ /* will be set to the signalled */ /* state when an ASYNCH command */ /* completes */ } NCB, *PNCB; Documentation: NCB@msdn on MSDN
