code-injection

问题 I've been looking at enough blogs so I'm pretty sure how it's coded... but none of them seem to mention where the javascript injection goes in the Obj-C code? Basically all I want to do is get rid of a header on all the pages the user can navigate to (or at least the page that initially loads... I'll worry about subsequent pages later if it's an issue. keep it simple, stupid ). Here's the code I have: [self stringByEvaluatingJavaScriptFromString:@"document. getElementById('login').childNodes

问题 I'm talking about Delphi + ADO + MSSQL. Okay, I know that queries with parameters are quite safe against SQL-injections. On the other hand, dynamic queries are quite not safe. But what about classic FieldByName methods? Can I safely assign to FieldByName an ABSOLUTELY any string value, without risking to have an injection? 回答1: It is safe. Ado is using parameters for Update/Insert/Delete. You can trace this with SQLProfile, e.g. exec sp_executesql N'UPDATE "test".."Activity" SET "data"=@P1

问题 Is there a way to access the name of a "Child" struct from methods on the "Parent" struct when using anonymous method embedding. For Example: type Animal struct{} func (a Animal) SayName() string { v := reflect.TypeOf(a) return v.Name() } type Zebra struct { Animal } var zebra Zebra zebraName := zebra.SayName() // "Animal" want "Zebra" The SayName() method returns the type.Name() of the "Parent". I realize I could do something like this, but since this for an API and will be reused often. I

问题 I am learning how to create a Firefox add-on. I want to do a simple add-on that will inject a script in a page. I have read the documentation but I can't solve this problem. in the cfx run logs, I can see that it runs the script various times in the same page when it should do it only once. main.js var pageMod = require('sdk/page-mod') var data = require('sdk/self').data pageMod.PageMod({ include: ['*'], contentScriptWhen: 'end', contentScriptFile: data.url('starter.js') }) starter.js var

问题 When is the correct time to use mysql_real_escape_string? Should I be using it when I use isset(mysql_escape_string($_GET['param'])), Should I be using it when I use $foo = mysql_real_escape_string($_GET['bar']); Thanks 回答1: You need to call this function when building SQL queries with string literals. You should not call it anywhere else. The point of calling this function is to prevent you from executing SQL like SELECT * FROM Students WHERE Name = 'Robert'); DROP TABLE Students;--' . mysql

问题 I was trying to make a Code Playground like Tinkerbin. It basicaly takes the CSS / HTML / Javascript Code out of different Textareas and injects it into an Iframe. It also should instantly update the Iframe. However I'm a little bit stuck with injecting the Javascript. See, what I have done thus far: (function() { $('.grid').height( $(window).height() ); var contents = $('iframe').contents(), body = contents.find('body'), styleTag = $('<style></style>').appendTo(contents.find('head')); $(

问题 How to prevent iframe from loading when injected into the DOM? For example, this code creates an iframe with a src that begins a download. f = B.Node.create('<iframe class="offscreen" role="presentation" tabindex="-1" id="' + d + '" src="' + Z + Y + '">'); F("body").appendChild(f); Without any libraries, what are ways to prevent the iframe from loading or to stop the download? Preventing the iframe injection is also acceptable. Is it a good idea to modify the behavior of "appendChild()"? I'm

问题 Yes, I know dependencies should be passed to the constructor. I'm not asking about coding styles or do's and dont's. Many of the classes in my application are tied to an instance of a database driver class. For this I've created an abstract Factory class using PHP's late static binding. The only member of this class is a property to hold the driver's reference. It looks like this: abstract class Factory { static private $__instances; static private $__default_driver; protected $_driver;

问题 I'm trying to extend a freeware, proprietary piece of .Net 2.0 software, and it's been giving me grief. I successfully managed to inject a Win32 dll and get it to successfully load in the .Net dll into the primary app domain, but doing so caused their custom GUI system to lock up completely. Is it possible to get a reference to a remote AppDomain (running in another app) and perform operations on it (e.g. load an assembly, create a class)? The reason I'm asking is that I'm sure I saw

问题 I have the following code public DataSet GetProject(string projectID) { DataSet dataTable = new DataSet(); DataAccess dataAccess = new DataAccess(); OracleCommand commandOb = new OracleCommand(); strQuery.Append("select projectName, managerName"); strQuery.Append("from project "); strQuery.Append("where projectID = '" + projectID + "'"); cmd.CommandText = strQuery.ToString(); dataTable = dataAccess.ExecuteDataAdapter(commandOb); return dataTable; } Is this an okay way to build a query and
