You need to do this every time you start a new project involving the Winsock Control. Cannot translate a name. This is how to invoking a method:                          Control.Method Argument1, Argument2, Argument3 ‘No value is returned        Variable = Control.Method(Arg1, Arg2, Arg3) ‘value is assigned to Variable       Events Port The remote IP port number.

Winsock Tracing

Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. This normally results if the peer application on the remote host is suddenly stopped, the host is rebooted, the host or remote network interface is disabled, or the remote host uses Receive Posted Event ID = 19 Level = 5 (Verbose) In order to diagnose user buffer corruption (for example, when an application re-uses the same buffer in another send or receive

  1. WinSock description: Same as Berkeley. "You can't make a silk purse from a sow's ear." Detailed descriptions: accept(), listen(): socket is not of type that supports connection-oriented service.
  2. For instance, this error will occur if you try to run two applications that have FTP servers.
  3. A name component or a name was too long.
  4. WSANO_DATA 11004 Valid name, no data record of requested type.
  5. Every error description contains at least: Summary Info: Error macro: manifest constant, as defined in WINSOCK.H Error value: as defined in v1.1 WINSOCK.H Short description Berkeley description: text describing the equivalent
  6. However, you also say SendData can't be used if you're already connected.
  7. SendTo Posted Event ID = 21 (IPv4), Event ID = 22 (IPv6) Level = 5 (Verbose) In order to diagnose user buffer corruption (for example, when an application re-uses the same

WinSock functions: WSAENETDOWN (10050) Network is down. send() & sendto(): socket not bound (for Dgram) or not yet connected (for Stream) The v1.1 specification also has a detailed description for the connect() function which says: "socket not already Did you type that by mistake or am I missing something? An address incompatible with the requested protocol was used.

The data that is sent and received by Winsock is sent through a buffer. Winsock Network Event 1003 Error The error code returned for the select or WSAPoll operation.   WSAEventSelect Event ID = 32 Level = 5 (Verbose) The following Winsock events are traced when an application calls The system returned: (22) Invalid argument The remote host or network may be down. https://msdn.microsoft.com/en-us/library/windows/desktop/bb892104(v=vs.85).aspx WSA_QOS_EUNKOWNPSOBJ 11024 Unrecognized QoS object.

WinSock description: Unlike Berkeley Sockets, in WinSock WSAEALREADY means that the asynchronous operation you attempted to cancel has already been canceled. Can indicate a service provider implementation error. Try a traceroute to the destination address to check that all the routers are functioning. Specifically, v1.1 WinSock spec notes that this error occurs if the length of the buffer is too small.

Winsock Network Event 1003

This event is executed when the textbox loses focus. For chained buffers, this parameter is the virtual address of the first buffer in the chain. Winsock Tracing Buffer The virtual address of the buffer. WinSock functions: Additional functions: any function that takes a socket (or file handle) as an input parameter See also: WSAENOTSOCK WSAECONNABORTED (10053) Software caused connection abort.

WSAENOTEMPTY 10066 Directory not empty. http://pdctoday.com/winsock-error/winsock-error-232.php The following parameters are logged for data indicated from transport events: ParameterDescription Process The kernel EPROCESS structure address for the process. sckWouldBlock 10035 Socket is non-blocking and the specified operation will block. This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running.

The name is not an official host name or alias, or it cannot be found in the database(s) being queried. Errors are listed in numerical order with the error macro name. The following parameters are logged for a socket close event: ParameterDescription Process The kernel EPROCESS structure address for the process. weblink Finally, if for some reason you need to turn all error checking off you can do the following:      On Error Goto 0 The code tells the computer to not go

Berkeley description: A protocol was specified that does not support the semantics of the socket type requested. Instead it fails with WSAETIMEDOUT. Socket handles re-used by calls to the AcceptEx or ConnectEx functions.

Developer suggestions: WSAStartup() failed, and you didn't detect it, or it wasn't called for the current task at all, or you called WSACleanup() too many times.

User suggestions: Do you have the WinSock DLL that supports the version of the WinSock specification required by the application? You can also use this process to load other ActiveX controls, such as the CommonDialog control. sckConnecting 6 Connecting. Along with the Winsock State Constants you can easily determine what ‘state’ the control is in.

Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence. This is usually a temporary error during host name resolution and means that the local server did not receive a response from an authoritative server. Developers should consider handling the referenced errors similarly. check over here sckAddressInUse 10048 Address in use.

This error is relevant to connect(), but not to send() or sendto() as it is in Berkeley Sockets.
