Hi, This is more of a design question than a specific code question, I'm sure I am missing the obvious, I just need another set of eyes. I am writing a multi-client server based on WSAAsyncSelect, each connection is made into an object of a connection class I have written which contains associated settings and buffers etc. My question...
If I use send() on a non-blocking tcp socket in Linux will it return EAGAIN for anything other than a send buffer full condition? I basically need to decide if I want to use the socket send buffer as the only buffer for my app or if I need my own user space buffer to feed the socket buffer. ...
Hello, is there a library or a class that would allow me to record on going packets from my computer (which is done on tools such as ETHEREAL[WIRESHARK] & WPE PRO(if you happen to be a gamer). To then resend it on a loop. I'm trying to make a service that would interact with my router on a timely basis. Thanks ;). ...
Is it ever possible for the C send function to return zero when using TCP sockets? The man page just says that it will return the number of bytes sent, but I am not sure if it will just return -1 when it can't send any data. ...
Is it possible to send nothing to an object? Let me elaborate. For instance I could have something like this: val = some_stack.include?(some_val) ? some_val : nil obj1.obj2.send(val).obj3.obj4 The above call wont't work because nil is not a symbol. So the solution is: if val.nil? obj1.obj2.obj3.obj4 else obj1.obj2.send(val).ob...

Hello, I tried to send SYN packets on my local network and monitoring them with Wireshark and everything works just fine, except when i try to send a packet to my own ip address it "seems" to work because it says Sent 1 packet, but it is not really sent, i can't see the packet in Wireshark nor any answers to the packet.

In my program I have a dialogue-themed activity that pops up with an edittext and submit button that sends an sms message. After the message is sent I want the phone to go back to whatever activity it was doing before (the dialogue is started by a broadcast receiver) however SMSManager's sendTextMessage(...) method takes a pending inte...
I remember having read somewhere that a socket can be regarded as two independent half-duplex channels. Does it mean that recv() and send() of the same socket are actually irrelevant? if so, is it by definition or implementation-specific? if not, how the two interfere with each other? thanks. ...
Hey All, I was just wondering if anybody else has had the same problem as me. I am trying to send emails from a simple form using ASP.NET (VB/C# I don't really care), and what does my head in severely is the fact that it seems so much harder to send an email using ASP.NET than it is in WinForms! In WinForms, I can write some code to s...

Hello. Can anyone explain how to send variables from the web (PHP, Javascript, etc.) to a C# program? I want to allow the web to tell the program what to do. Maybe I could use AJAX to send data to an auto-updating page, which the C# program can then read? That would also allow users to be logged-in to the page and therefore different dat...
