    - by Haroldo
    I can't remember what the method is meant to be for ensuring the scope of a variable in a query is restricted to prevent mysql injection. where should i put brackets in the following examples? UPDATE table SET col_1 = '$var', col_2 = '$var2' WHERE col_1 = '$var3' and SELECT * FROM table WHERE WHERE col_1 >= '$var1' (Obviously looking for answers not using PDO!)

  • Using PreferenceScreen/PreferenceActivity to configure home screen widgets

    - by hpe
    Hi, I'm creating an appwidget, where the user should be able to configure it before it is added to the home screen. To me, PreferenceScreen/PreferenceActivity seems perfect for the task, but the intention behind these classes seem to be configuring an actual application. I've searched, but cannot find any documentation or tutorials which covers this question. Is it possible to configure a widget using these classes, or is the only alternative to configure it through an ordinary view? Thanks for any answers!

  • How can I build a voting system to support multiple types of objects to vote on?

    - by Kyle Hayes
    I'm really looking for something very similar to the way SO is setup where a few different kinds of things can be voted on (questions AND answers). What kind of DB schema, generally, could I use to support voting on many different kinds of objects? Would I have a single Vote table that would have references to other objects in the database? Or do I have to have or should have a separate vote table for each of the objects I would like to vote on.

  • How could I generate instances of an object randomly at the top of the screen and make them "fall"?

    - by Custard
    I am making a game in Flash CS4 (actionscript 3) and I would like to be able to make "copies" of an instance that would randomly appear at the top of the screen and fall. For example, multiple objects(that are the same one) are falling from the top of the screen continuously, starting at random X positions. (i think this would be considered Real-Time effect). P.S., please tell me if the information is insufficient for an answer, I couldn't think of much more to add to it. Thanks for your time and answers, -Custard

  • Collection, which method is used to authorize an add of an element ?

    - by Duke Vador
    We find a lot of concrete subclasses under Collection. While trying to add an element in a concrete collection, this collection will use a method to determine if it can accept to store the element (and eventually that this element is not already in the collection). It could use equals(), hashCode() or compareTo() of the element. Is it possible to find a summary about which method is used by each implementation of Collection ? Thanks a lot for your answers.

    - by avp
    Hi, I'm looking for free tools to design the UI for my web app. I'm pretty new to this field, so please point me to acceptable solutions. Basically, I need to fill a "screen" with some controls, that's it. Thanks. EDIT: Well, as soon as nobody answers, maybe somebody can help me with this problem for some framework other than Cappuccino?

  • Return statements for all functions

    - by emddudley
    How common is it for coding style guidelines to include a requirement that all functions include a return statement (including functions which return void)? To avoid being subjective or argumentative, I'd like answers which can name specific companies or open-source projects which have this requirement. If you haven't ever come across this coding style guideline, or you have a resource (book, online article) which discusses it, that would be useful as well. Thanks!

  • Ask Field formatting

    - by developer
    I am using ASK fields in a word document, wherein the user are prompted with questions and the document is then built with the answers that the user type in. My question is that word does not allow more that 200 characters in the prompt box wherein the user types in the questions. Is there a way I can increase its maxlength. Also I want to change the font color of the question asked in the prompt box. Is it possible?

  • Change encoding to UTF-8 recursively on Windows?

    - by Pekka
    Does anybody know a tool, preferably for the Explorer context menu, to recursively change the encoding of files in a project from / to UTF-8 and other encodings? Freeware or not too expensive would be great. Edit: Thanks for the answers, +1 for all of them as they are all fine but I am a lazy bastard sometimes, and would really like to be able to just right click a folder and say "convert all .php files to UTF-8". :) Further suggestions are appreciated.

  • How to send data from site to browser?

    - by SaltLake
    I'd like to send data to browser from server (website). For example on SO you receive notifications about new answers when answering a question. Should I every n seconds send ajax queries to server, or there are better ways of doing this? Is it possible to push data from server to browser?

  • FOSS solution for a local machine: DNS

    - by Shyam
    Hi, I love my Mac. But I have always found that my DNS lookups are as slow, even while flushing caches and I travel over know roads on the Internet. I was wondering if someone would know something a bit more automatic/intelligent than /etc/hosts and less complex and iron forged as BIND. Thank you for your feedback and answers!

  • What does the exception "javax.servlet.jsp.JspException: Broken pipe" signify?

    - by Ruepen
    I'm getting the following error: javax.servlet.jsp.JspException: Broken pipe Now I have seen questions/answers with respects to the socket exception, but this error is coming from a different package. Any help is greatly appreciated. BTW, I am seeing quite a lot of these errors in a struts web app Weblogic Node logs and I am thinking that it has to do with end users closing their web browser before the page reloads/executes the next step (database transaction which takes quite a bit of time to execute, anywhere from 30 seconds to 4 mins).

  • Delphi component you can't live without?

    - by Warren P
    Most delphi developers have a list of delphi components they wouldn't live without. Not including anything that ships with Delphi (standard VCL or included third-party software like Rave or Indy), what are the components you can't live without, be they commercial or open-source? I will refrain from adding my own answers unless this becomes a community wiki. One component name, or product name, per answer please. Please vote up on components and do not post duplicates.

  • Getting the type of a parametrized class parameter?

    - by GuidoMB
    I have the following class public class MyClass<T> { public Class<T> getDomainClass() { GET THE CLASS OF T } } I've googled this problem and all the answers I could find told me to use getGenericSuperClass(), but the problem of this method is that I must have a second class that extends MyClass and I don't want to do this. What I need is to get the parametrized type of a concrete class?

    Hi, I was going over some pages from WikiVS, that I quote from: because lambdas in Python are restricted to expressions and cannot contain statements I would like to know what would be a good example (or more) where this restriction would be, preferably compared to the Ruby language. Thank you for your answers, comments and feedback!

  • Errors in c++ faq lite?

    - by Gianluca
    Hello, I'm reading questions and answers around here for a few days. I have seen the c++ faq lite at Parashift has been mentioned many times. Personally I have always considered it to be a good reference, not my favourite one but certainly useful. Here I have seen somebody advising it, but many others commenting against it instead. Somebody mentioned it's full of mistakes. Could you please point out which are the major errors in there, if any?
