问题 I'm trying to make Erlang program that finds prime numbers with processes (ineffective, I know, but hey, it's just for fun :) ) - something along the lines of numbersimulation.com. On each "tick" the server spawns new process ("number") that increments its counter. If counter == that number, it's a factor, so we let server know. If server doesn't get any messages, it's a prime number. On small numbers (primes upto N, the server(50,L) line) it's okay, but on the bigger ones it crashes with:

问题 working in C#, I use SharpPCap to get segments from a winpcap trace. I need to rebuild all the messages sent and received in that trace. In my situation, the client's and server's IP will never be the same. Client's port does not necessarily change. The protocol used by the message could be HTTP or something custom that I don't know. That's how I currently do it : if (ipPacket.Protocol == IPProtocolType.TCP) { TcpPacket tcpPacket = (TcpPacket)ipPacket.PayloadPacket; Packet dataPacket =

问题 I am new in Codeigniter and I need to show success and error message after insert data's in database. How can I show the message in the view page? This is my coding: Model function addnewproducts($data) { if($data['product_name']!="" && $data['product_qty']!="" && $data['product_price']!="" && $data['date']!="") { $res=$this->db->insert('product_list',$data); return $this->db->insert_id(); } else { return false; } } Controller function addnewproduct() { $this->load->model('products'); $data[

问题 I have successfully developed a BlackBerry App that registers for BlackBerry Push Messaging Service and receives push message. The Push Message is received as a pop-up message. I am handling at the back end to show this message inside the App in a Chat Screen that I have created. The push message when sent to the device is stored in a database as well. The App has a timer running that queries the database for any new message and displays it inside the app. However this approach is not so

问题 I have a problem with handling batch processing with spring integration. Normally After splitter, all the element(Message) will be assigned with a correlation_id for future grouping in Aggregator, but the problem is that when there is a exception thrown when processing the element(Message), a MeesageException will be created and the correlation_id is lost. I can use HeaderEnricher to add the correlation_id but it cannot be hard coded I assume, other wise if there are multiple requests come

问题 I'm using acts-as-messageable, a rails gem, in an app i have. However in my messages_controller i have def new @message = ActsAsMessageable::Message.new end and in my view i have <%= form_for(@message) do |f| %> which throws the following error undefined method `acts_as_messageable_messages_path' I'm not really sure why this is happening with the gem. 回答1: Try explicitly stating what path you want the form to point towards (which should be the messages#create action): <%= form_for(@message)

问题 I am reading this blog: Use Threads Correctly, and I am wondering: How to implement a message ( Note: I don't mean Windows Message here ) pump in a non-UI thread? What I want is that the message can be an object or a command, say an Action<T> / Func<T> , etc. Do I have to use separate queue for different type of message? Say one queue for object, one queue for Action<T> / Func<T> ? Given that the type of messages vary, how to implement it? EDIT: What I want to complete is a producer/consumer

问题 I want to delete all the sms from the mobile through my application. Currently, I am deleting messages using below code. Uri uriSms = Uri.parse("content://sms/"); Cursor c = getContentResolver().query(uriSms, new String[] { "_id", "thread_id", "address","person", "date", "body" }, null, null, null); if (c != null && c.moveToFirst()) { do { long id = c.getLong(0); getContentResolver().delete(Uri.parse("content://sms/" + id), null, null); } while (c.moveToNext()); } I am able to delete messages

问题 What I want to do is this: I have a pom.xml that depends on some property that the user will have to type as he calls mvn by an -D property. The problem is, if the user don't give me this option, the mvn should fail with an custom error message, as "This program won't compile because you must define this property..." Does anyone know what's the simplest way to make this happen? I don't want to create a plugin that throws an Exception just to do this. 回答1: The Maven Enforcer Plugin already has
