C++0x lambdas are monomorphic, while bind can be polymorphic. You cannot have something like auto f = [](auto a, auto b) { cout << a << ‘ ‘ << b; } f(“test”, 1.2f); a and b must have known types. On the other hand, tr1/boost/phoenix/lambda bind allows you to do this: struct foo { typedef … Read more
You can always bind values within the arguments of execute() as long as you’re fine with the values being treated as PDO::PARAM_STR (string). $result_set = $pdo->prepare(“INSERT INTO `users` (`username`, `password`, `first_name`, `last_name`) VALUES (:username, :password, :first_name, :last_name)”); $result_set->execute(array( ‘:username’ => ‘~user’, ‘:password’ => ‘~pass’, ‘:first_name’ => ‘~John’, ‘:last_name’ => ‘~Doe’ )); You can use the … Read more
Although what @machineghost said was true, that events are added and removed the same way, the missing part of the equation was this: A new function reference is created after .bind() is called. See Does bind() change the function reference? | How to set permanently? So, to add or remove it, assign the reference to … Read more
Scott Meyers gave a talk about this. This is what I remember: In C++14 there is nothing useful bind can do that can’t also be done with lambdas. In C++11 however there are some things that can’t be done with lambdas: You can’t move the variables while capturing when creating the lambdas. Variables are always … Read more
In your case it was some other process that was using the port and as indicated in the comments, sudo netstat -pna | grep 3000 helped you in solving the problem. While in other cases (I myself encountered it many times) it mostly is the same container running at some other instance. In that case … Read more
Using PHP 5.6 you can do this easy with help of unpacking operator(…$var) and use get_result() insted of bind_result() public function get_result($sql,$types = null,$params = null) { $stmt = $this->mysqli->prepare($sql); $stmt->bind_param($types, …$params); if(!$stmt->execute()) return false; return $stmt->get_result(); } Example: $mysqli = new database(DB_HOST,DB_USER,DB_PASS,DB_NAME); $output = new search($mysqli); $sql = “SELECT * FROM root_contacts_cfm WHERE root_contacts_cfm.cnt_id … Read more
Why is JavaScript bind() necessary? The value of this is determined by how a function is called. If it is you who calls the function then there is usually no need to use .bind, since you have control over how to call the function, and therefore its this value. However, often it is not you … Read more
ngModel listens for “input” event, so to “fix” your code you’d need to trigger that event after setting the value: $(‘button’).click(function(){ var input = $(‘input’); input.val(‘xxx’); input.trigger(‘input’); // Use for Chrome/Firefox/Edge input.trigger(‘change’); // Use for Chrome/Firefox/Edge + IE11 }); For the explanation of this particular behaviour check out this answer that I gave a while … Read more
All functions are also descriptors, so you can bind them by calling their __get__ method: bound_handler = handler.__get__(self, MyWidget) Here’s R. Hettinger’s excellent guide to descriptors. As a self-contained example pulled from Keith’s comment: def bind(instance, func, as_name=None): “”” Bind the function *func* to *instance*, with either provided name *as_name* or the existing name of … Read more
this inside a function call gets set according to how a function is called. There are six main ways that this gets set. Normal Function Call: In a normal function call such as foo(), this is set to either the global object (which is window in a browser or global in nodejs) or to undefined … Read more
