问题 I am new to this networking in iOS so doesn't know all the concepts so well and I'm making an app which allows to show data on browser which is on device, For that I'm creating a socket-port and using SwiftSocket library override func viewDidLoad() { super.viewDidLoad() let ip = String(getAddress(for: .wifi)!) self.host = ip print("Getting IP address of wifi\n\(self.host)\n") self.selfserver() } I think following function selfserver() initialises the server and wait for the client to connect

问题 I am trying create a small web application that allows a user to "login" and "logout." What I am currently having a problem with is allowing the client to send constant "heartbeats" or messages to the server to notify that it is still active. This is more of a logical question. What I want to do is have a while(1) loop in php that checks if n number of heartbeats have been skipped. I still want the client and server to be able to interact while this loop is going on (essentially I want the

问题 Let's say I've got a website that works better if a client has installed and logged into a desktop application. I'd like to be able to do 2 things: Alter the website if they haven't installed the app (to make it easy for them to find a link to the installer) If they've installed the app on a couple of machines, determine which machine they are browsing from I'd like something that works on Windows and OSX, on any of the major browsers. Linux is a bonus. A few thoughts: Websites can detect if

问题 UPDATE: As for my original question, it turns out that call to java.security.KeyStore.getCertificate(alias) does actually return X509Certiciate. That wasn't the issue though. (Bear with me please, I'm new to this certificate stuff.) I managed to connect to my (self-signed) SSL-enabled server, as long as I don't require authenticated clients. When I do require clientAuth my app yields "routines:SSL3_READ_BYTES:sslv3 alert handshake failure (external/openssl/ssl/s3_pkt.c"... (also described

问题 Let's say you have several accounts attached to your Outlook client and want to be able to choose which one to send a mail from using VBA. What do you do? The MailItem.SendUsingAccount parameter looks the right way to do this and is recommended elsewhere like here or here or here. However, if you apply the example in the Developer Reference, setting the SendUsingAccount property to valid Accounts may be impossible. Why? This appears to be the answer : You must Dim your MailItem as an Object
