问题 I created a phpMailer class and call it into my register.php file all fine. But dont find a way how to send emails from class. Here is my class: class mailSend { public function sendMail($email, $message, $subject) { require_once('PHPMailer/src/Exception.php'); require_once('PHPMailer/src/PHPMailer.php'); require_once('PHPMailer/src/SMTP.php'); $mail = new PHPMailer\PHPMailer\PHPMailer(); try { $mail->SMTPDebug = 0; $mail->isSMTP(); $mail->Host = "smtp.gmail.com"; $mail->SMTPAuth = true;

问题 I'm making a blackjack program in Java, and I was starting to write the class declaration for an object Card. Will this be sufficient, or are there some methods I should have that I'm glossing over? public class Card { public int suit; //Value 1-4 to represent suit public int value; //Value 1-13 to represent value (i.e. 2, J) public Card(int suit, int value) { //Not yet implemented } } Also, is there a good way to have an something like C++'s enum data structure in Java, because that would be

问题 There must be something very simple that I'm missing here. I have a MATLAB class which creates a figure containing two push-buttons, each button calls the same function, but the handles for those buttons aren't retained within that function, and I don't know why. Here's the class, simplified... classdef Test properties Figure ButtonA ButtonB end methods function app = Test() app.Figure = figure(); app.ButtonA = uicontrol('Style', 'pushbutton', ... 'String', 'Button A', ... 'Position', [10, 10

问题 I'm learning Java and I noticed that the main() is put inside of a class. Why? I don't consider my main() to be a member of any object. So please tell me how I can get around this. 回答1: I don't consider my main() to be a member of any object. It's not since it's a static method. It does not belong to any object but to the class itself. Aside from that, all methods, including main must be defined in classes. More generally, a class is the smallest unit in compiled Java code and contains both

问题 I have multiple Members, and each one has a record which contains several memo fields: Member ID Entry A Entry B 1 [memo text] [memo text] 2 [memo text] [memo text] 3 [memo text] [memo text] In Access 2007, I am creating a Memo Entry form that is the equivalent of Shift-F2 -- A dedicated window to review and edit the content. Unlike Shift-F2 , this must be reusable. I must mention that the form for showing details about a Member is also reusable. Following the plan above (which is abbreviated

问题 I was wondering if it's possible to use star unpacking with own classes rather than just builtins like list and tuple . class Agent(object): def __init__(self, cards): self.cards = cards def __len__(self): return len(self.cards) def __iter__(self): return self.cards And be able to write agent = Agent([1,2,3,4]) myfunc(*agent) But I get: TypeError: visualize() argument after * must be a sequence, not Agent Which methods do I have to implement in order to make unpacking possible? 回答1: The

问题 We've got 2 models & a join model: #app/models/message.rb Class Message < ActiveRecord::Base has_many :image_messages has_many :images, through: :image_messages end #app/models/image.rb Class Image < ActiveRecord::Base has_many :image_messages has_many :messages, through: :image_messages end #app/models/image_message.rb Class ImageMessage < ActiveRecord::Base belongs_to :image belongs_to :message end Extra Attributes We're looking to extract the extra attributes from the join model (

问题 I have an inventory program written to include an array and a method to calculate total cost for all inventory items entered. I now have to include a subclass that overrides the original to include "one unique feature". I created a new file named ItemDetails to set up for the subclasses of the original Item. I need to include one unique feature and calculate the value of the inventory and calculate a 5% restocking fee in this subclass. Do I just transfer some of the relevant lines into the

问题 .net 3.5, VS 2010... this is for an asp.net website. I have an class called Agency. there is a second class called Agency_Queries. Agency_Queries inhertis the Agency class. I'm trying to create a function that will copy the like properties in Agency to Agency_Queries. I figured out how to do that.. but when i try to make it more generic so that i can pass in my class name and lists i'm doing something wrong. So if there is an list(of Agency) that needs to be copied to list(of Agency_Queries)

问题 I'm making a forum application with various levels of authorization, one of which is a Monitor. I am doing this by extending my User class, and I plan on fine tuning this with "-ship" classes (e.g. administratorship, authorship, moderatorship, etc.). Apparently the Monitor class is part of ruby mixin. How do I keep my resource name without the collisions? 回答1: Some possibilities: avoid the require 'monitor.rb' call which is pulling in the standard Monitor instance do some runtime magic to
