Vote count: 0 NSString *message = @"This part: "Is in quotations""; I'm wondering if it's possible to color the part of the NSString inside the quotations a different color? I understand this example: Is it possible to change color of single word in UITextView and UITextField but not sure how to convert it to my example since I have multiple slahes. asked 2 mins agoApollo Let's block ads! بخوانید...

Vote count: 0 Consider the following code public class myClass{ myClass instanceOfNotYetDefinedClass; ... //etc code } I don't understand how the compiler manages to understand that: I'm telling it to create a class, and then it says: "OK! Let me see what this myClass class has. Oh, its a myClass, let me see whats this has..." etc. It may be a pretty noobish question, but I really don't understand how this could be handled. asked 2 mins agoYoTengoUnLCD Let's block ads! بخوانید...

Vote count: 2 I have a basic sketch of implementing a multithreaded web proxy: FILE *proxy_log_file; static void SIGUSR1_handler(int sig) { (void)sig; fflush(proxy_log_file); } int main(int argc, char **argv) { proxy_log_file = fopen("proxy.log", "a"); Signal(SIGUSR1, SIGUSR1_handler); } The idea is that network admins can flush buffered log entries to a log file by using the kill command to send a SIGUSR1 signal to the web proxy. However, I'm not sure it's a good idea to call fflush inside the signal handler. I know fflush is thread-safe but don't think it's async-signal-safe. What concurrency problem could arise from calling fflush inside a signal handler of a multithreaded? asked 1 min ag...

Vote count: 0 I have a Signalr Hub called NotificationHub that handles sending new notification to coected clients. The NotificationHub class uses a NotificationManager class to retrieve notifications data. Now, I want to be able to use a session to store the last time a new notification has been accessed but when using HttpContext.Current.Session["lastRun"] in NotificationManager I get a NullReferenceException. To clarify more, here is some of the codes of both classes: NotificationHub [HubName("notification")] public class NotificationHub : Hub { private NotificationManager _manager; private ILog logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); ...

Vote count: 0 I know a dollar sign is a replacement for 'jQuerry' and is used for accessing functions and variables from the jQuerry object.

Vote count: 0 I would like to know if elasticsearch considers empty string as null value, but based on my mapping shown below, I don't see that it is doing that. How can I make elasticsearch consider empty string as a null and index using the value provided by null_value.

Vote count: 0 I'm working on an Angular 2 app and keep wondering how to best componentize the UI design I have come up with: Basically, I have a side menu from where I can select a topic, e.g. "Sales". In addition, I pick an employee from the context menu on the right to display the topic for. The question now is, how do I go about making these into components now? It somehow would feel natural to have URLs such as http://foo.com/#/sales/123 with a route configured like so { path: '/sales/:employeeId', name: 'Sales', component: SalesComponent } However, if I change the topic from "Sales" to, say, "Contacts" (still within the context of the employee I have previously chosen), then the links i...

Vote count: 1 What I am trying to do is use aws-lambda to import zipped sql files in aws-rds. In my case zipped sql files are inserted in s3 constantly by some crawlers. What I want to do is when any sql file is uploaded to an s3 bucket, I want aws-lambda to use a mysql-client to import these files into aws-rds. They way I have think of doing this is by packaging a mysql-client inside the zip for the aws-lambda handler. But I can't really figure out how to package mysql inside a zip. Is this possible? If yes, then a list of steps to achieve this would be really helpful! PS: I am using python-2.7 for writing the aws-lambda handler. I am not interested in using any python-mysql library to achi...

Vote count: 0 I am using a gulp task to gzip my source files and set into a dist folder. I am able to successfully generate xyz.tar.gz file, but when I try to see the files in it using a 7zip on windows 7, I see a lot of files named "PaxHeader" each of different size. Tried searching on inteet, but results were more of gzip related and unable to understand. Can someone let me know why this is happening? Is it a gzip related issue or a wrong configuration of gulp-gzip? TIA asked 2 mins agovamshi4001 Let's block ads! بخوانید...

Vote count: 0 I know this seems like a straight forward question - but although Moment.js and moment timezone are very powerful tools for getting/setting and formatting dates.. I'm having an issue snapping my application to a single timezone. What I want, is for a user to choose from a date/time picker - and to send that as a unix timestamp in UTC.. but the date/time picker MUST be considered to be BST. In other words, even if you're using the site from abroad - the date/time you select should be the UTC value for if you had chosen it in the UK. var local = moment(dateTime).unix(); var london = moment(dateTime).tz('Europe/London').unix(); var berlin = moment(dateTime).tz('Europe/Berlin').uni...

Vote count: 0 This is a working program that I've been trying to lea C++ from that inputs from a file strings and doubles and puts them into their perspective arrays. What I'm stuck on is while sorting the strings I want to sort the array of doubles in ascending order and keep the scores with the name they are associated with. I'm trying to lea it without using vectors before I go on to lea how to manipulate them, that's the reason for not using vectors before anyone asks. Is it best to sort the columns of the 2d array and than sort them with the 1d array or just to have a statement that does it all? Also what would be the best sorting algorithm for this application?
