send

I need to work Location API for android where first the data is to be stored on Local Sqlite datbase in android itself each 15 minutes and then send it to a server, so that data can be tracked offline too. Any suggestions, code or help is really appreciated ! You, can simply create a background service then implements a location listener. In that location listener, you can set the time interval in the requestLocationUpdate method to ping the GPS at particular time intervals. or you can use timertask to send gps at particular intervals Here is a location manager instance: lm

I have an image sitting on my SDcard (of type jpg) and I am trying to send the image via HttpPost to my servlet running on Apache Tomcat 7.0 So far I have google-ing the way to do this but I can't seem to find the perfect way. Do any of you might have some suggestion or solution to this problem? Thank you in advance, Sammy Stevan Djap HttpClient is the class to use and there's a tutorial for it. See the section Using HTTP client , right after the pictures. UPDATE What follows is commentary on the tutorial example from Developerlife.com . A good thing about that example is that it demonstrates

Following is the scenario: A <-------------------------> B I am using non-blocking Sockets on both A and B (linux based machines). A and B have a TCP connection and suddenly the link connecting them goes down (The link may not be direct link). Now after the link is down, when send() function is called on side A to send some data to B , It returns successfully (i.e it returns the number of bytes that are to be sent). What is the reason for this behavior, when we know the remote side will not be able to receive this data, when the link is down? This is normal and expected behaviour. when we know

I have a client and server program where I want to send an entire struct from the client and then output the struct member "ID" on the server. I have done all the connecting etc and already managed to send a string through: send(socket, string, string_size, 0); So, is it possible to send a struct instead of a string through send()? Can I just replace my buffer on the server to be an empty struct of the same type and go? Welll... sending structs through the network is kinda hard if you are doing it properly. Carl is right - you can send a struct through a network by saying: send(socket, (char*

The following is the setup: Server Client | | accept connect | | v | send msg1-> | | | v v recv <- send | | v v send msg2-> recv | | v v close Here is my question: 1. Client actually receives msg1 before it closes, why is it like this? 2. send msg2 returns normally. Since client closes after receiving msg1, why is send msg2 successful? P.S. I'm using stream socket for TCP. The recv function will get whatever is next in the receive buffer. In the case of the client, if the socket is a datagram socket, what is next is msg1 . If it is a stream socket then message boundaries are not maintained so

I have been working on a simple python socket chat room where the client and server can send messages to each other. The issue that I came across was that the server and client can only send one message at a time. I want it to work like any other chat room, where I could receive a message when I am sending a message, any help will help greatly Server.py import socket import sys s = socket.socket() host = socket.gethostname() print(" server will start on host : ", host) port = 8080 s.bind((host,port)) name = input(str("Please enter your username: ")) print("") print("Server is waiting for

I need send a imageview like i send the string "title", but i can't, how can i send a imageview (R.drawable.image) from mainactivity to secondactivity? THANKS MAIN ACTIVITY public void NewActivity(View view){ Intent intent = new Intent(this, SecondActivity.class); intent.putExtra("title", getString(R.string.title)); startActivity(intent); } SECOND ACTIVITY @Override public void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.pantalla); Bundle extras = getIntent().getExtras(); if (extras == null) { return; } String title = extras.getString("title"); TextView textview =

I know send takes string or symbol with arguments while instance_eval takes string or block, and their difference could be apparent given receivers. My question is what the ' under the hood ' difference is for the example below? 1234.send 'to_s' # '1234' 1234.instance_eval 'to_s' # '1234' From the fine manual : send(symbol [, args...]) → obj send(string [, args...]) → obj Invokes the method identified by symbol , passing it any arguments specified. [...] When the method is identified by a string, the string is converted to a symbol. and for instance_eval : instance_eval(string [, filename [,

I have a little 'incidental' question: When sending a request with Ajax ... open has to antecede send , for sure... but what about the onreadystatechange allocation? Logically set before open -ing the Request object, after send -ing or in between? To get'em back'n'ya mind: // Using POST XMLHttp.open('POST', url, true); XMLHttp.onreadystatechange = RequestState; XMLHttp.send(parameter); Generally speaking, if the only readyState that you care about is 4, then it doesn't really make a difference if the onreadystatechange event handler is assigned prior to calling open(), in between open() and
