[Qt-interest] WG: QT Assistant and ports

[Lodron, Gerald]

I checked it several times, i defenitely do not make a second connection. As i said, everythings work prior the opening of assistant.exe
 
Here my code:
 
try{

if (mSocket != NULL){

delete mSocket;

mSocket = NULL;

}

sockinetbuf sin (sockbuf::sock_stream);

try

{

sin.bind( mInfo.GetCalledIPPort() ); //does not work on assistant.exe, mInfo.GetCalledIPPort() is the port adress

}

catch(sockerr &e)

{

std::cout << e.what() << ": " <<e.operation() << std::endl;

std::cout << "Error code: " << WSAGetLastError() << std::endl; //here i get 10048

sin.shutdown(sockbuf::shut_readwrite);

return false;

}

sin.recvtimeout(1);

sin.sendtimeout(1);

sin.listen();

if (sin.is_readready(1, 0))
{

mSocket = new iosockinet(sin.accept());

} 
else 
{

return false; //no connection here, so have to initialize later.

}
} catch (std::exception& ex){//unable to establish connection, so break off.
     return false;
}

Or check carefully that you don't make the connection twice.

	Did you check if, by pure accident, QtAssistant doesn't want to just use
	the exact same port you are using?
