Winsock Error Handling
If it does respond, then this problem might have been a transient one (so you can reconnect now), or the server application you were connected to might have terminated (so you For example, the ARPA Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM. Typically, though, Winsock generates WSAENETUNREACH when it receives a 'host unreachable' ICMP message from a router instead of WSAEHOSTUNREACH. Most of the text comes from the output from the "man errno" command on Unix. Source
If it doesn't respond, it might be off-line or there may be a network problem along the way. The next method of error checking involves using the Visual Basic error handling commands.

One point of interest is the requirement of closing the control before you connect to another computer. https://msdn.microsoft.com/en-us/library/windows/desktop/cc507522(v=vs.85).aspx
Winsock Error Windows 7
Assuming you have a name server configured instead of or as well as a host table, a hostname resolution request causes a WinSock DLL to send a DNS "A" record query Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address. Detailed description: recv() and recvfrom(): if the datagram you read is larger than the buffer you supplied, then WinSock truncates the datagram (i.e. Assuming you have a name server configured instead of or as well as a host table, a hostname resolution request causes a Winsock DLL to send a DNS 'A' record query
WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), See also: WSAHOST_NOT_FOUND, WSANO_RECOVERY, WSATRY_AGAIN WSANO_RECOVERY (11003) This is a non-recoverable error Berkeley description: This is a This has no network-relevant analog (although the "inode" reference could refer to a network file system entry). Any application that uses a blocking socket or calls any blocking functions must handle this error. Winsock Error Windows Xp Berkeley description: The protocol family has not been configured into the system or no implementation for it exists.
Each ActiveX control is made up of three important components: Events, Properties and Methods. Winsock Error 10061 It is a nonfatal error, and the operation should be retried later. a "high-level" protocol). http://www.win32developer.com/tutorial/winsock/winsock_tutorial_5.shtm WSA_QOS_EPSFLOWSPEC 11027 Invalid QoS provider-specific flowspec.

Winsock Error Windows 7 You about buffers and how messages are stored on a buffer before being sent to the remote user, and how the message is stored on the buffer before being downloaded again Winsock Error 10054 We appreciate your feedback.
Returned when a system call that should never fail does fail. this contact form No more results can be returned by the WSALookupServiceNext function. Developer suggestions: Since there're only one corresponding protocol for each of the datagram and datastream socket types in the Internet address family, you should simply leave the value in the protocol So, if we run the application it will report the following error in our console. Winsock Error 10053
WSA_QOS_BAD_STYLE 11012 QoS bad style. Of the two that can fail, neither of them set an error value you can retrieve from WSAGetLastError() (refer to Chapter 10, "Support Routines" for more information on any of these WinSock description: Same as Berkeley. http://hardwareyellowpages.com/winsock-error/winsock-error.html It also has a specific meaning for setsockopt().
A service provider returned a bogus procedure table to Ws2_32.dll. Socket_error Define WSAENOTCONN 10057 Socket is not connected. Note that this error occurs rarely, because a Winsock implementation cannot reliably detect hardware problems.WSAENETUNREACH (10051) Network is unreachable A socket operation was attempted to an unreachable network.
You should try designing an application that connects to a server in order to get comfortable with connections in Winsock.
- If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly.
- The specified class was not found.
- For protocol and services resolution, the name or number was not found in the respective database.
But that's not to say you shouldn't still be prepared. WSAHOST_NOT_FOUND for details.WSANO_ADDRESS (11004)* No address, look for MX record The requested name is valid, but does not have an Internet IP address at the name server. The "address" it refers to is the remote socket name (protocol, port and address). Socket Error 10054 Connection Reset By Peer I've been using kana reminder for a couple of years now.
The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). See also: WSANO_DATA, WSANO_RECOVERY, WSATRY_AGAIN WSANOTINITIALISED (10093) Successful WSAStartup() not yet performed Berkeley description: No equivalent. If you have more than one server configured, the hostname query fails only after the Winsock DLL has queried all servers. http://hardwareyellowpages.com/winsock-error/winsock-10057.html Cannot translate a name.
WSA_NOT_ENOUGH_MEMORY 8 Insufficient memory available. It may also make explicit mention of other functions that can fail with this error. For example, this error is returned if sendto is called with the remote address of ADDR_ANY. Do you have the Winsock DLL that supports the version of the Winsock specification required by the application?
WSAECONNRESET (10054) Connection reset by peer A connection was forcibly closed by a peer. For this tutorial we will be working with the final code used back in tutorial 2 (the blocking server). However this is very tedious to enact on a much larger scale, especially because sometimes the program will be sending non-user drive events.
