send

问题 I have to send my GPS coordinates via SMS, How can I take the latitude and longitude values in SMS body? I tried something but i cant make it with +@id/lat or +String.valueOf(location.getLongitude() in intent.putExtra("sms_body","there would be latitude and longitude values.."); Here is the SmsActivity.java public class SmsActivity extends MainActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);

问题 I am attempting to make a simple server so that two clients can communicate with each other. The main server code accepts the two client connections and then forks off a process that uses execl to generate a personal server between the two clients so that the main server can continue looking for new connections. Everything seems to work correctly until the personal server attempts to contact the clients and they both receive gibberish, if anyone knows what could cause this please let me know.

问题 I'm learning sockets programming in c (Linux), and I can't really understand why is it necessary to use htonl when you are sending an integer, but not when you are sending a string (char*). I've read a lot of papers, but I still don't know why. 回答1: It's because data sent through networks are sent in Big Endian order. Different platforms store data in different orders. Say you have a short of 0x9FD3. On a Small Endian platform, it'll be stored in memory as 0xD39F. The first byte is 0xD3, and

问题 What is the sending interval of RTCP Receiver Report? In RFC 3550 I was only able to find computation the RTCP Transmission Interval for the server. But as a client I have no idea about members and senders (or do I?). So I'm a little bit confuse how to calculate the interval or should I send RTCP RR in periods or should I only send RR packet when SR is received? 回答1: The RTP and RTCP protocols don't make a distinction between client and server. Both are members within the RTP session and both

问题 it should be easy, but I couldn't find a proper solution. for the first level keys: resource.public_send("#{key}=", value) but for foo.bar.lolo ? I know that I can get it like the following: 'foo.bar.lolo'.split('.').inject(resource, :send) or resource.instance_eval("foo.bar.lolo") but how to set the value to the last variable assuming that I don't know the nesting level, it may be second or third. is there a general way to do that for all levels ? for my example I can do it like the

问题 i've recently encountered a problem trying to share large data among several processors using the command 'send' from the mpi4py-library. Even a 1000x3 numpy float array is too large to be sent. Any ideas how to overcome this problem? thx in advance. 回答1: I've found a simple solution. Divide data into small enough chunks... 回答2: I encountered this same problem with Isend (not with Send ). It appears that the problem was due to the sending process terminating before the receiver had received
