How can I combine elements at the same index from separate lists?

An unhandled exception of System.InvalidOperationException breaks my MVC App?

c#,asp.net-mvc-5,antiforgerytoken

This article might help: Unfortunately this error is a little confusing because it says “nameidentifier or identityprovider” even though you may have one of the two. By default you need both. Anyway, if you’re not using ACS as your STS then the above error pretty much tells you what’s needed...

Reading file with fgets() leaves new line character at the end of each line

php,file,explode

1. Since you use fgets(), yes this is the expected behaviour, since you grab the full line, which includes the new line character at the end. 2. You can just use fgetcsv() and specify the delimiter as tab, e.g. $handle = fopen("test.csv", "r"); if ($handle) { while (($data = fgetcsv($handle,...

C++ - Why does 2 local references to the same object stay in sync?

c++,pointers,syntax,reference,variable-assignment

string & ref1 = *it; string & ref2 = *it; Okay, so you create two references to the same string. ++it; // After this line, both ref1 && ref2 evaluates to "a" Right, because they are both references to the same string. This is the way you created them. ref2...

CPAN module prereqs

perl,cpan

The Makefile.PL doesn't install prerequisites; it just complains if they're not installed. It's the CPAN client's job to install prerequisites. Note: Module::Install has an auto_install feature that does this, but the general consensus seems to be that using it is a bad idea....

Pipe not working

node.js,request

If you see req.body set to something, that means the request has already been processed, so there is nothing to pipe to your file WriteStream. So you need to either move your body parsing middleware so that they are only executed for routes that need them, or (as more of...

Why is backspace allowed in my jQuery whether I filter it out or not?

jquery,ascii,keypress,backspace

If you really want to prevent backspace, you should unbind the default event and re-attach a 'new' version of it. Try something like: $(document).unbind('keydown').bind('keydown', function (event) { var doPrevent = false; if (event.keyCode === 8) { var d = event.srcElement || event.target; if ((d.tagName.toUpperCase() === 'INPUT' && (d.type.toUpperCase() === 'TEXT'...

Getting four bits from the right only in a byte using bit shift operations

c,syntax,bit-manipulation,bitwise-operators

Shift operator only only works on integral types. Using << causes implicit integral promotion, type casting b to an int and "protecting" the higher bits. To solve, use temp = ((unsigned char)(b << 4)) >> 4;...

How to make morre readable URIs using unique-id-plus-redundant-information (UPRI) using PHP with Laravel

rest,laravel-5,url-routing

You can use eloquent-sluggable to create slugs for your users. That way the slug will change when they update their username. You can also simply call their username in the url method, though this will result in uglier urls. This method still requires that you drop Route::resource() and write your...

java,testing,junit

Can you pls try this... if(foundFile()) { return prop.getProperty("DAILY-DMS.instances"); } prop object is populated only after foundFile() call, however you are reading the data in a prior line. Also, unless you are updating the config file in runtime, I would recommend you read the properties file one and store it...

Java 8 - Call interface's default method with double colon syntax

java,inheritance,lambda,java-8

One way would be to put the compare method in a static method: public static interface IdEntity extends Comparable<IdEntity> { int getId(); @Override default int compareTo(IdEntity other) { return defaultCompare(this, other); } static int defaultCompare(IdEntity first, IdEntity second) { return first.getId() - second.getId(); } } Then your method would be:...
