it is difficult to look up a document for every function especially when i don't know the functions needed. do you know of any fully completed examples/source code?

so i'm missing the recvform function?


WSADATA wsaData;
SOCKET ListeningSocket, NewConnection;
SOCKADDR_IN ServerAddr;
int Port = 7171;
char recvbuff[1024];
int i, nlen;

i thought i only needed to change this line:

ServerAddr.sin_addr.s_addr = INADDR_ANY;

ok so i changed it to INADDR_ANY but i'm still getting the same error with listen

but i understand. so INADDR_ANY is used in the server and INADDR_BROADCAST is used in the client

sorry those links don't work for me

i was told to use it. its a requirement

not one that uses broadcast. its very difficult to find. if you could link any examples that would be great

i have changed so much code so i started again.
here is the current code:


WSADATA wsaData;
SOCKET ListeningSocket, NewConnection;
SOCKADDR_IN ServerAddr;
int Port = 7171;
char...

ok so the error i get with listen is 10045 which is:


i don't know how to solve this problem. description of the error doesn't help

i assumed the code from the MSDN website would be right.
ok its set to true now
it is still displaying the error for setsockopt and now it is also displaying the error message from this code:

...

that code is from MSDN. should it be true?
it is set to false at the start but then down a few lines it is set to true
is this a mistake?

the code executes setsockopt and jumps into the else statement
this time the WSAGetLastError is 0
then it executes sendto and displays the WSAGetLastError which is still 10013

the only change i made was moving some code around


void CSocketTestServerDlg::StartServer()
{
//---------------------------------------
// Declare variables
int iResult = 0;
WSADATA...

the reason for the error is from the 10013 error which is:
An attempt was made to access a socket in a way forbidden by its access permissions. An example is using a broadcast address for "sendto"...

well i don't what the problem is. those are the only lines that don't get executed and then i reach the error message

ok i debugged it and went through each line
these are the lines that don't get executed:
WSADATA wsaData;
SOCKADDR_IN brdcastaddr;
char sbuf[1024];

i never realized the line didn't get executed.
is it because its in the wrong place?

final code:


void CSocketTestServerDlg::StartServer()
{
//---------------------------------------
// Declare variables
int iResult = 0;
WSADATA wsaData;
iResult =...

that is the old setsockopt. sorry i just commented it out instead of removing it
i rewrote it when i added the error message code as you can see if you look at the code i posted and look for...

please look at post #19
i edited the code and put in the line //----------- set socket ---------// so it is easy to find

but i have done that:

setsockopt(m_serversocket, SOL_SOCKET, SO_BROADCAST, (char *) &bOptVal, bOptLen);

yes i know what that error means


but i then started adding all the error messages so the problem was never solved. what do i need to do to fix it?

ok i moved some code around. the problem was it wasn't reading a socket.
now the only error message displaying is the one that started this problem:
ERROR binding with server socket 10013

all...

ok i fixed that error i was getting.
now a load of the error messages i added are displaying when u run the program:
getsockopt for SO_KEEPALIVE failed with error: 10038
setsockopt for...
