问题 I am trying to create an automated program in Python that deals with Flash. Right now I am using Python Mechanize, which is great for filling forms, but when it comes to flash I don't know what to do.

问题 I'm new to IOC containers, and I'm getting started with NInject. What do you do if you want your constructor to have parameters that are not services and don't need to be instantiated by the IOC container? For example: public class Person { private readonly string _name; private readonly IPersonRepository _repository; public Person(string name, IPersonRepository repository) { _name = name; _repository = repository; } ...... } Imagine that name is a requirement of the Person class, so, to

问题 Problem Using CDI I want to produce @ApplicationScoped beans. Additionally I want to provide a configuration annotation to the injection points, e.g.: @Target({ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER}) @Retention(RetentionPolicy.RUNTIME) public @interface Configuration { String value(); } I do not want to write a separate producer for each different possibility of value . Approach The usual way would be to make a producer and handle the injection point annotations:

问题 I want to make a quick and easy demonstration about how SQL injection work. And I've solved some of my problems. I have a table with random usernames, passwords and emails in, and I'm able to "inject" SQL code to view all of the users in a search with this injection: ' OR '1'='1 This is how my PHP code looks for searching for "members": if (isset($_POST['search'])) { $searchterm = $_POST['searchterm']; echo $searchterm . '<br>'; /* SQL query for searching in database */ $sql = "SELECT

问题 I'm using programmatic injection to inject my extension's code into a page only when the browser action is clicked. This is what I have on my extension's event page (per the example in the documentation): chrome.browserAction.onClicked.addListener(function callback(tab){ chrome.tabs.executeScript(null, {file: "content-script.js"}); }); However, the way this works, the script is injected every time the button is clicked. How can I change it so that the script is not injected on subsequent

问题 I Just noticed that my mysql_real_escape_string function is not inside a '' in some of my php scripts and it was vulnerable to injections and things like sleep(30) executed on my production site. I am going the PDO route and implementing the prepared statements after lots of reading here. but this is not implemented yet.

问题 I found this piece of code here: http://php.net/manual/de/reserved.variables.get.php Want to use it to make my code safer. I use quite a few $_GET var in my project.
