client

问题 I currently have a problem using UDP and Python socket module. We have a server and clients. The problem occurs when we send data to a user. It's possible that user may have closed their connection to the server through a client crash, disconnect by ISP, or some other improper method. As such, it is possible to send data to a closed socket. Of course with UDP you can't tell if the data really reached or if it's closed, as it doesn't care (atleast, it doesn't bring up an exception). However,

问题 I've been trying to solve a little problem for quite a while now but it seems I'm not able to. I wrote an HTML page which calls a perl CGI script upon submitting a form. This CGI executes a certain number of tasks server-side and I made the script print the steps of these tasks into an iframe on the HTML page. The thing is, if the client closes his browser or just goes out of the page, the CGI script is interrupted on server-side. HTML code: <form action="/path/to/script.cgi" method="post"

问题 I have a server that gathers information and broadcasts some messages across the local network. I'm using boost::asio to broadcast these via UDP on port 8079 and I can verify with WireShark that these packets are actually broadcasted as intended. Now, naturally, I want to follow up with a listener that can react to these messages, but I am struggling to receive anything. My current approach is: boost::asio::io_service io_service; boost::asio::ip::udp::socket socket(io_service); boost::asio:

问题 Just recently I was creating new maven project on new computer and it seams that the dependency for jboss as client isn't available anymore: <dependency> <groupId>org.jboss.jbossas</groupId> <artifactId>jboss-as-client</artifactId> <version>5.1.0.GA</version> <type>pom</type> <scope>provided</scope> </dependency> And the repository resource is: <repositories> <repository> <id>jboss-maven2</id> <url>http://repository.jboss.com/maven2</url> </repository> </repositories> Is there any new

问题 I'd like to know how to convert Perforce depot locations to client view locations for the purpose of script writing. I have a script that first checks out a file for edit in perforce and then interacts with the file. I need to have the depot location (i.e. \Projects\Project6) converted to the client view location. (i.e. d:\Projects\Project6). Is this possible? 回答1: I have always used the p4 where command for this. Here is its description from the built-in help: where -- Show how file names

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I have a list of full remote host ip addresses. I wrote a script to connect all the hosts in this list, one by one. My question is, sometimes when an IP address is down, script waits for a while (maybe a couple of minute) to go and execute next host. So I would like to decrease this waiting time. For example

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 4 years ago . I've had several clients ask this, and I've never been able to get or give a satisfactory answer. Can you (practically) put a working form into an HTML email? My understanding is that you can, but that there's no guarantee of email clients properly handling it, so that method

问题 I have a few computers working as WCF clients and they are connected to a computer who works as the WCF service. Now lets say one client connection is lost (i.e. the cable disconnects), How can I know that happened on the service side? I tried to use the wcf callbacks events Closing/Closed but I did not get the call. I am writing in C#. Best Regards. Adi. 回答1: Callbacks dont work because your client cannot tell to service "i'am close connection with you". What you need is heartbeat - periodic

问题 I have not worked extensively on Client Side/Front End of the Application and I am trying to read about HTML, CSS and DOM but somehow am not able to figure out difference between them and so would really appreciate if someone can: Explain me in simple English how does HTML, CSS and DOM work ? How do they relate to each other from Client Side Technology point of view ? Update I have gone through wikipedia articles but not able to clearly understand working of DOM. Thanks. 回答1: HTML is what is
