Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

A whole lot of troubles with sockets and TCP

So, I've made a tcp client with both sender and receiver capabilities, based on Rama's UDP client. The only thing I changed is this line

 SenderSocket = FUdpSocketBuilder(*YourChosenSocketName).AsReusable().WithBroadcast();

To FTcpSocketBuilder (omitting .WithBradcast() in the way). Also, SendTo() doesn't actually work without first doing

 senderSocket->Connect(*remoteAdress);

HOWEVER

Recv() works very strange. bytesPending equals 8 bytes, the message that was sent to me by server. Hovever bytesRead goes 0. Why can't it read anything, though it totaly came through.

ALSO

Send() doesn't actually deliver anything. It's not "not sending", because bytesSent is 12. But server doesn't actually get anything. When I tried to send something to server through unity it was delivered, that's why I think the problem is in my code.

Half the problem solved itself, somehow. By changing Send() to SendTo() I managed to get my message to server, though I can't tell why it behaves like that.

Have you found a fix to this?
