call

问题 Now I have two classes allmethods.cs and caller.cs . I have some methods in class allmethods.cs . I want to write code in caller.cs in order to call a certain method in the allmethods class. Example on code: public class allmethods public static void Method1() { // Method1 } public static void Method2() { // Method2 } class caller { public static void Main(string[] args) { // I want to write a code here to call Method2 for example from allmethods Class } } How can I achieve that? 回答1: Because

问题 Quite recently I read about JavaScript call usage in MDC https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/call one linke of the example shown below, I still don't understand. Why are they using inheritance here like this Prod_dept.prototype = new Product(); is this necessary? Because there is a call to the super-constructor in Prod_dept() anyway, like this Product.call is this just out of common behaviour? When is it better to use call for the super-constructor or

问题 sorry I really should of asked why there is a differnce , `Object.prototype.toString.call(o).slice(x,y);` and this? o.toString().slice(x.y); // why those are different , call should change the 'this' value for the called method // and toString is already inherited , var x = 44 ; `Object.prototype.toString.call(x)`; //"[object Number]" x.toString(); // '44' 回答1: You're not calling .call on the method here: Object.prototype.toString(o).slice(x,y); Instead, you just call the method (on the

问题 I am using the MySQL Connector. using (MySqlConnection connection = new MySqlConnection("...")) { connection.Open(); MySqlCommand command = new MySqlCommand(); command.Connection = connection; command.CommandType = CommandType.StoredProcedure; command.CommandText = "FN_NEW"; command.Parameters.AddWithValue("P_SESSION_ID", sessionId); command.Parameters.AddWithValue("P_NAME", deckName); object result = command.ExecuteScalar(); // returns NULL !!!!!!!!! return Json(result); } For some reason

问题 I tried searching around but didn't seem to find an answer to my problem, so I'm sorry if I missed something and it actually has been answered before. So basically I have main.py and another file called check.py (both in same directory) In my main.py I have: from check import checkfunction I have a small function inside main.py that I MUST call inside check.py, but I can't seem to get this import working on my check.py: from main import mainfunction How can I get the mainfunction to work

问题 currently I have a application which can send notifications, I would like this application to be able to send these notifications automatically every x minutes (for example, 15 minutes is the default). The app may or may not be currently running when this notification should be sent. After some reading, I've determined that an AlarmManager would be used here, but I cannot figure out how to call a method from it. I already have the notification code, I just need a way to call it every x

问题 I want that both dialog and incoming call screen be clickable. I have tried different solutions from this site, but some works in some condtions and others don't. I want to create an app like true caller, I have called an activity from BroadcastReceiver . My code works perfectly when the screen is not locked because the incoming screen is not full screen. But when the screen is full screen the dialog activity appears for few milliseconds over the calling screen and then goes behind the

问题 This is related to generate groups in BuddyPress. I have a spreadsheet with (in this case) a group name, group description and slug. I need to grab the information from the file, turn it into an array, then loop through it and call groups_create_group() every time. I can find that function in bp-groups.php (http://www.nomorepasting.com/getpaste.php?pasteid=35217). It tells me all the parameters you need to fill in. I'm quite new to this and looking for how I can do this. Do you know how I can

问题 I'm having some trouble understanding how system calls come into play in android app execution. From my understanding of android app execution, .class file is translated into dalvik bytecode (DEX) which is combined together to form ODEX. ODEX is then compiled with JIT compiler directly into machine code for execution. In this case, how does system call on android's linux kernel comes into play? In addition, is there any possible way to monitor these system calls? 回答1: System calls are the

问题 For an embedded DSL I want classes to behave like a function. It seems easy for instances (https://www.dartlang.org/articles/emulating-functions/) but I couldn't make it happen for classes. I tried creating a static call a method but this didn't work either. Is there a way or do I have to give the class another name and make Pconst a function, calling the constructor? class Pconst { final value; Pconst(this.value); static Pconst call(value) => new Pconst(value); String toString() => "Pconst(
