You’re trying to pass a member function pointer as a normal function pointer which won’t work. Member functions have to have the this pointer as one of the hidden parameters, which isn’t the case for normal functions, so their types are incompatible. You can: Change the type of your argument to accept member functions and … Read more
It may be related to a misconfiguration in your /etc/hosts. In my case, it was like this: 192.168.1.11 localhost instead of 127.0.0.1 localhost
Try this: $(‘.initiator’).on(‘mouseenter mouseleave’, function(e) { $(‘.receiver’).trigger(e.type); }) It will apply the same triggers for the receiver as the initiator receives for both mouseenter and mouseleave. Note that: .hover(over, out) is just a high-level variant of: .on(‘mouseenter’, over).on(‘mouseleave’, out) so using that information you can be more precise when binding and triggering mouse events.

call_user_func_array “Call a callback with an array of parameters” call_user_func_array(array($stmt, “bind_param”), array_merge(array($type), $params)); should do the job UPDATE: you have also to change your params array: $params = array(&$firstName, &$lastName, &$address, &$postcode, &$email, &$password); as mysqli_stmt::bind_param expects the second and the following parameters by reference. EDIT: Your query seems to be wrong. Maybe you have … Read more
For read-only controls they are the same. For 2 way databinding, using a datasource in which you want to update, insert, etc with declarative databinding, you’ll need to use Bind. Imagine for example a GridView with a ItemTemplate and EditItemTemplate. If you use Bind or Eval in the ItemTemplate, there will be no difference. If … Read more
It must be like this: //connect $mysqli = new mysqli($host, $user, $password, $db_name); //prepare $stmt = $mysqli->prepare(“SELECT * FROM the_table WHERE field1= ? AND Field2= ?”); //Binding parameters. Types: s = string, i = integer, d = double, b = blob $params= array(“ss”,”string_1″,”string_2″); //now we need to add references $tmp = array(); foreach($params as $key … Read more
This is quite impossible. The whole reason that std::function exists is that function pointers suck horrifically and should never, ever, be used by anyone, ever again, except for the doomed souls bearing the Burning Standards of Hell C interoperation, because they cannot handle functions with state. A std::function<void()> cannot, in the general case, be converted … Read more
bind() was added in 1.0, live() in 1.3, delegate() in 1.4.2 and on() in 1.7. As of 1.7 on() is the preferred use and live() is deprecated and not recommended at all. If you are using 1.3 use bind() instead of live() and as of 1.4.2 use delegate() instead of live() and as of 1.7 … Read more
The do.call function is very useful here: A <- 1:10 B <- 11:20 C <- 20:11 > do.call(cbind, list(A,B,C)) [,1] [,2] [,3] [1,] 1 11 20 [2,] 2 12 19 [3,] 3 13 18 [4,] 4 14 17 [5,] 5 15 16 [6,] 6 16 15 [7,] 7 17 14 [8,] 8 18 13 [9,] … Read more
std::bind expressions, like their boost::bind predecessors, support a type of composition operation. Your expression for w is roughly equivalent to auto w=std::bind(some_fun, std::bind(&foo::bar<int>, x, std::placeholders::_1) ); Nesting binds in this manner is interpreted as Calculate the value of x.bar<int>(y) where y is the first parameter passed into the resulting functor. Pass that result into some_fun. … Read more
