• How to protect yourself from XSS when you allow people to post RAW embeded codes?

  - by Axel

  Hi. Tumblr and other blogging websites allows people to post embeded codes of videos from youtube and all video networks. but how they filter only the flash object code and remove any other html or scripts? and even they have an automated code that informes you this is not a valid video code. Is this done with REGEX expressions? And Is there a PHP code to do that? Thanks

• Face detection in 100% pure PHP

  - by Yogi Yang 007

  I am looking for PHP script that will detect face in a uploaded photo and automatically crop it accordingly. The code should be in pure PHP without depending on any third party API's or Libs. This code will be a part of our existing code for processing images. In fact this is the only part that is missing! I would prefer to have code in PHP version 5.x not PHP 6.x.

• TFS CM resource recommendations / some questions

  - by John

  I am working with a small development shop that consists of a group of 5 developers and 1 QA person. We are using TFS and need to get more sophisticated on how we use this tool. Currently the development team checks in their code each evening. A nightly build runs and pushes the output out on a network share. Our QA person uses this build for testing the next day. Sometimes the build off the trunk codebase has issues/bugs that hinder the QA process, and it hasn’t been a giant issue in the past, but we now want to get to a state where we have our QA person testing on a stable QA build. So I believe we need to create a branch (call it QA), and the developers will continue to develop off the trunk, but the QA person will use builds created from code in the QA branch. Seems simple enough, but we have started doing code reviews as well. So we have another desire in that only code that has been code reviewed can be promoted to the QA branch. Each developer works off a TFS item, and when they check in a changeset, they do it against a TFS item which creates a link between a checked in code file and a TFS item. Eventually the TFS item becomes complete and ready for code review. All code attached to the TFS item is reviewed. How can the versions of these files get promoted to the QA branch? In the QA branch, if a bug is found, we want to fix it in the QA branch and have the changes migrated back to the trunk. I believe TFS has a way to automatically do this doesn’t it? Long story short, we want to get to a build and CM environment that I believe is pretty standard, but we are unaware of how to make this happen with TFS. Given our situation above, can someone point out a book or website(s) that would address our specific needs? We would like to make this happen without having to get too deep in CM theory or TFS. I very much appreciate any and all suggestions! Thanks, John

• I'm getting an error in my Java code but I can't see whats wrong with it. Help?

  - by Fraz

  The error i'm getting is in the fillPayroll() method in the while loop where it says payroll.add(employee). The error says I can't invoke add() on an array type Person but the Employee class inherits from Person so I thought this would be possible. Can anyone clarify this for me? import java.io.*; import java.util.*; public class Payroll { private int monthlyPay, tax; private Person [] payroll = new Person [1]; //Method adds person to payroll array public void add(Person person) { if(payroll[0] == null) //If array is empty, fill first element with person { payroll[payroll.length-1] = person; } else //Creates copy of payroll with new person added { Person [] newPayroll = new Person [payroll.length+1]; for(int i = 0;i<payroll.length;i++) { newPayroll[i] = payroll[i]; } newPayroll[newPayroll.length] = person; payroll = newPayroll; } } public void fillPayroll() { try { FileReader fromEmployee = new FileReader ("EmployeeData.txt"); Scanner data = new Scanner(fromEmployee); Employee employee = new Employee(); while (data.hasNextLine()) { employee.readData(data.nextLine()); payroll.add(employee); } } catch (FileNotFoundException e) { System.out.println("Error: File Not Found"); } } }

• Append a large li to ul: best way?

  - by zsharp

  I have a li that has numerous nested divs. I am appending to a ul as follows: $("ul#List").append('<li><div>....many more nested divs...</li>'); the structure of the li is the same as the other lis in ul but i have to modify some elements. My question is simply am I doing it wrong by manually writing out the entire structure?

• usage of try catch

  - by Muhammed Rauf K

  Which is best: Code Snippet 1 or Code Snippet 2 ? And Why? /* Code Snippet 1 * * Write try-catch in function definition */ void Main(string[] args) { AddMe(); } void AddMe() { try { // Do operations... } catch(Exception e) { } } /* Code Snippet 2 * * Write try-catch where we call the function. */ void Main(string[] args) { try { AddMe(); } catch (Exception e) { } } void AddMe() { // Do operations... }

• Marshal.PtrToStructure (and back again) and generic solution for endianness swapping

  - by cgyDeveloper

  I have a system where a remote agent sends serialized structures (from and embedded C system) for me to read and store via IP/UDP. In some cases I need to send back the same structure types. I thought I had a nice setup using Marshal.PtrToStructure (receive) and Marshal.StructureToPtr (send). However, a small gotcha is that the network big endian integers need to be converted to my x86 little endian format to be used locally. When I'm sending them off again, big endian is the way to go. Here are the functions in question: private static T BytesToStruct<T>(ref byte[] rawData) where T: struct { T result = default(T); GCHandle handle = GCHandle.Alloc(rawData, GCHandleType.Pinned); try { IntPtr rawDataPtr = handle.AddrOfPinnedObject(); result = (T)Marshal.PtrToStructure(rawDataPtr, typeof(T)); } finally { handle.Free(); } return result; } private static byte[] StructToBytes<T>(T data) where T: struct { byte[] rawData = new byte[Marshal.SizeOf(data)]; GCHandle handle = GCHandle.Alloc(rawData, GCHandleType.Pinned); try { IntPtr rawDataPtr = handle.AddrOfPinnedObject(); Marshal.StructureToPtr(data, rawDataPtr, false); } finally { handle.Free(); } return rawData; } And a quick example structure that might be used like this: byte[] data = this.sock.Receive(ref this.ipep); Request request = BytesToStruct<Request>(ref data); Where the structure in question looks like: [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)] private struct Request { public byte type; public short sequence; [MarshalAs(UnmanagedType.ByValArray, SizeConst = 5)] public byte[] address; } What (generic) way can I swap the endianness when marshalling the structures? My need is such that the locally stored 'public short sequence' in this example will be little-endian for displaying to the user. I don't want to have to swap the endianness on a structure-specific way. My first thought was to use Reflection, but I'm not very familiar with that feature. Also, I hoped that there would be a better solution out there that somebody could point me towards. Thanks in advance :)

• How to get MinValue/MaxValue of a certain ValueType via reflection?

  - by marco.ragogna

  I need to this at runtime. I checked using Reflector and value types line like Int16, for example, should contain <Serializable, StructLayout(LayoutKind.Sequential), ComVisible(True)> _ Public Structure Int16 Implements IComparable, IFormattable, IConvertible, IComparable(Of Short), IEquatable(Of Short) Public Const MaxValue As Short = &H7FFF Public Const MinValue As Short = -32768 End Structure But the following code is not working Dim dummyValue = Activator.CreateInstance(GetType(UInt16)) Dim minValue As IComparable = DirectCast(dummyValue.GetType.GetProperty("MinValue").GetValue(dummyValue, Nothing), IComparable) any idea how to solve?

• Programming Constructs History

  I need some help in figuring out which language introduced the constructs that we use everyday. For example: Constructs Introduced from LISP If-Else Block :"The ubiquitous if-then-else structure, now taken for granted as an essential element of any programming language, was invented by McCarthy for use in Lisp, where it saw its first appearance in a more general form (the cond structure). It was inherited by Algol, which popularized it. " - WikiPedia Function Type : Functions as first class citizens. Garbage Collection

• How can I map one to one relationship in Fluent NHibernate. I have tried everything else

  - by RM

  I have this table structure and would like to map it using Fluent Hibernate (subclass if possible). I cannot change the structure because the database has too many records and might cause major applications rework. It would be easier if the Id from Party table was a foreign key in person and organization table, but in the particular scenario the database has person and organization key as a foreign key in party table. Any help would be great. Party table Id PersonId OrganizationId Person table Id FName LName Organization table Id OrgName OrgDescription

• CSS Calendar Display

  - by Steven

  I created my own custom date picker consisting of an ASP TextBox, Button, and Calendar complete with CSS styles, javascript code, and event handling vb code. I want to use this date picker multiple times on my form. I know the wrong way to do this would be to copy all the code and just adjust each name accordingly. How can I put those controls, styles, and code into a single entity?

• jets3t and Downloading Files from AmazonS3 with Different Name

  - by Gregg

  We're using AmazonS3 for file storage and recently found out that we need to keep some sort of directory structure. Since S3 doesn't allow that, we know we can name the files according to their structure for storage. For example... abc/123/draft.doc What I want to know is if I want to provide a public link to this particular file is there anyway that the file can simply be draft.doc instead of abc/123/draft.doc ?

• jqgrid and django models

  - by Andrew Gee

  Hi, I have the following models class Employee(Person): job = model.Charfield(max_length=200) class Address(models.Model): street = models.CharField(max_length=200) city = models.CharField(max_length=200) class EmpAddress(Address): date_occupied = models.DateField() date_vacated = models.DateField() employee = models.ForeignKey() When I build a json data structure for an EmpAddress object using the django serialzer it does not include the inherited fields only the EmpAddress fields. I know the fields are available in the object in my view as I can print them but they are not built into the json structure. Does anyone know how to overcome this? Thanks Andrew

• Calculate the Hilbert value of a point for use in a Hilbert R-Tree?

  - by wrt

  I have an application where a Hilbert R-Tree (wikipedia) (citeseer) would seem to be an appropriate data structure. Specifically, it requires reasonably fast spatial queries over a data set that will experience a lot of updates. However, as far as I can see, none of the descriptions of the algorithms for this data structure even mention how to actually calculate the requisite Hilbert Value; which is the distance along a Hilbert Curve to the point. So any suggestions for how to go about calculating this?

• How to set MQMD ApplicationID field via JMS API?

  - by Alon

  Hello, I'm using the JMS API to send messages to a Websphere MQ server. The application that pulls the messages i create want's me to set up the ApplicationID field in the MQMD structure to constant value. I could not find a way in the JMS API to access the MQMD structure The question: Is there a way doing this? if yes then how? If no, then is my only option is to use the MQ java API, instead of JMS API? Thanks

• jQuery UI draggable() and resizable()

  - by foxlance

  I want to write the draggable() and resizable() code in such a way that all future elements with a particular class will inherit those plugins without calling them again. $('div.resizeMe').resizable({ containment: 'parent', minWidth: 400, minHeight: 200 }) When the above code is executed, all divs with resizeMe class inherits the resizable() function. But if I appended BODY with a new div with the same class, I needed to execute that code again. So my goal here is how to rewrite that code such that it will work for all and including future elements.
