  • Send jQuery array to PHP post?

    - by FFish
    I have a javascript function that gathers two arrays, imagepaths and captions. I want to send with PHP's post to the same page $_SERVER['PHP_SELF'], but I really don't know where to start.. PHP: if (isset($_POST['Submit'])) { $edit_photos->update_xml($edit_photos->album_id, $_POST['src_arr'], $_POST['caption_arr']); // prevent resending data header("Location: " . $_SERVER['PHP_SELF'] . "?ref=" . $ref); } JS: function getImgData() { var imgData = { 'src_arr': [], 'caption_arr': []}; $('.album img').each(function(index){ imgData.src_arr.push($(this).attr('src')); imgData.caption_arr.push($(this).attr('alt')); }); return imgData; }; HTML: <form name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF'] . "?ref=" . $ref; ?>">

  • Cloning java ArrayList and preventing it from modifications

    - by user222164
    I have a data structure like a database Rowset, which has got Rows and Rows have Columns. I need to initialize a Columns with null values, current code is to loop thru each column for a row and initialize values to NULL. Which is very inefficient if you have 100s or rows and 10s of column. So instead I am keeping a initialized ArrayList of columns are RowSet level, and then doing a clone of this Arraylist for individual rows, as I believe clone() is faster than looping thru each element. row.columnsValues = rowsset.NullArrayList.clone() Problem with this is NullArrayList can be accidentally modified after being cloned, thus sacrificing the integrity of ArrayList at RowSet level, to prevent I am doing 3 things 1) Delcaring ArrayList as final 2) Any elements I insert are final or null 3) Methods thurough this arrayList are passed to other arrays are declared a final. Sounds like a plan, do you see any holes ?

  • Dynamically allocated structure and casting.

    - by Simone Margaritelli
    Let's say I have a first structure like this: typedef struct { int ivalue; char cvalue; } Foo; And a second one: typedef struct { int ivalue; char cvalue; unsigned char some_data_block[0xFF]; } Bar; Now let's say I do the following: Foo *pfoo; Bar *pbar; pbar = new Bar; pfoo = (Foo *)pbar; delete pfoo; Now, when I call the delete operator, how much memory does it free? sizeof(int) + sizeof(char) Or sizeof(int) + sizeof(char) + sizeof(char) * 0xFF ? And if it's the first case due to the casting, is there any way to prevent this memory leak from happening? Note: please don't answer "use C++ polymorphism" or similar, I am using this method for a reason.

  • Restrict folder sharing over cygwin sshd

    - by mtanish
    I recently installed a SSH server on my Windows 7 PC and created a separate user account for this. When i logged in using SSH, i could access all the windows directories. /cygdrive/c /cygdrive/d /cygdrive/e How do i prevent this user from accessing all the win directories other than its home directory under cygwin /home/chuck/ ? Preferably i do not want the user to even view /cygdrive when the user types "mount". Is there a easy way to do this? I want to later allow remote users to log on to this machine and avoid messing up other things.I know i can setup a separate machine but this is a plan for later.

  • displaying .aspx and .aspx.cs files such that its not understood by the browser

    - by user287745
    i have to give the user the option to upload his own aspx and aspx.cs files on to the server, adjust the hyperlink to point to a page which would do the following display the aspx and aspx.cs files code onto the page without actually rendering the code the browser should not understand anything, and while reading the files to display them the method be such that nothing is processed on the server regarding the code within the files to prevent from unnecessary problems many user would try to cause. i have tried many ways of displaying it but it ends up on displaying the actual comments instead of the code. please suggest with links to examples how to achieve the above. please note main concentration is on asp.net and c# using vs08, so j script and ready-made tools be avoided if feasible thank you all

  • Put text input inside label for radio button?

    - by Martijn
    I'm trying to make a radio group specifying a bunch of options, and an extra option "other" with a text input to specify. The code for this particular radio button I'm using is <input type='radio' name='RadioInput' value='Other' id='RadioInput_Other' /> <label for='RadioInput_Other'>Ohter: <input type='text' name='RadioInput_Other_Value' id='RadioInput_Other_Value' value='' /> </label> The idea is that if you give focus to the text input, the radio button corresponding to it is selected. The code above almost does this (since the text input is inside the label). However, it also shifts focus to the radio button (which is annoying, since whatever you type next is lost). Is there any way to prevent this using XHTML1.0 / CSS2? Preferably without using javascript.

  • GUI-Library for microcontroller

    - by Martin Kirsche
    I want to create a GUI driven application for a micro-controller (Atmel XMEGA) that is connected to a 128x64 dots graphics LCD (EA DOGL128-6) and 4 buttons for navigation. Controlling the display itself (e.g. drawing pixels and characters) is no problem but in order to prevent me from reinventing the wheel I was googling for a GUI-Library/-Toolkit that is written in c, includes its source code, will run on a 32 MHz 8-bit micro-controller and provides at least the following controls: panel (to group elements) menu (scrollable) icon label button line-graph (optional) But I didn't find any thing useful. Does anyone know (or better uses) such a library(preferably for free)?

  • Delphi form icons are blurry on Windows 7's taskbar (with MainFormOnTaskbar enabled)

    - by Dennis G.
    We have a Windows desktop application written in Delphi that works fine on Windows 7, except that the icon of the main form looks blurry in Windows' new taskbar. As long as the application has not been started the icon looks fine (i.e. when it's pinned to the taskbar). Once it has been started Windows uses the icon of the main form (instead of the .exe resource icon) and it's blurry (it looks like a 16x16 version of the icon is scaled up). The icon that we use for the .exe and for the main form are exactly the same and it contains all kinds of resolutions, including 48x48 with alpha blending. My theory is that Delphi ignores/deletes the extra resolutions of the icon when I import the .ico file for the main form in Delphi. Is there a way to prevent/fix this? What's the best way to ensure that an application written in Delphi uses the correct icon resolution in Windows 7's taskbar?

  • FxCop giving a warning on private constructor CA1823 and CA1053

    - by Luis Sánchez
    I have a class that looks like the following: Public Class Utilities Public Shared Function blah(userCode As String) As String 'doing some stuff End Function End Class I'm running FxCop 10 on it and it says: "Because type 'Utilities' contains only 'static' ( 'Shared' in Visual Basic) members, add a default private constructor to prevent the compiler from adding a default public constructor." Ok, you're right Mr. FxCop, I'll add a private constructor: Private Utilities() Now I'm having: "It appears that field 'Utilities.Utilities' is never used or is only ever assigned to. Use this field or remove it." Any ideas of what should I do to get rid of both warnings?

  • How to preserve hyperlink when submitting via php form into MySQL

    - by TheTub
    Hi All, I've created a form that stores free text fields into a MySQL database. All works fine and the data is displayed back as intended when viewed. Except for one niggle. In an attempt to prevent malicious attacks I have used mysql_real_escape_string to remove any unwanted code from the input. However, I need to be able to preserve hyperlinks and basic html. For example, I want to store the following: <p align="left">Please follow this <a href="link.html">link</a></p> But the link is being stored as \"link.html\" as the quotes are being escaped. How can I preserve this link and other html? Many thank TT

  • Bejeweled Blitz - How does it assert there is always a move?

    - by EvilTeach
    I have been playing Bejeweled Blitz for a while now. Yes, it is an addiction. In thinking about the game, I have observed that on some boards, the bottom runs dry (no moves) leaving only the top part of the board playable. Frequently that part of the board drys up, and one is left with moves in area cleared by the last move. The board never runs completely dry, so clearly the program is doing some sorts of calculation that allows it to choose what to drop to prevent it from running dry. I have noticed in this 'mode' that it is very common for the algorithm to drop jewels which causes more non-dry area to appear in the horizontal area. Perhaps less frequent is a drop which seems designed to open up the bottom part of the board again. So my question is "How would one go about designing an algorithm guarantee that there is always a move available.?"

  • DataAnnotations in ASP.NET MVC 2 - Stop MVC from applying RequiredAttribute to Non-nullable DateTime

    - by jwwishart
    Im trying to create a custom version of the RequiredAttribute to replace the built in one and I've got it working for properties that have strings values, but with properties that are DateTime or integer for example, the default RequiredAttribute seems to be applied automatically (IF the property is not nullable!) My problem is that i want to be able to specify a DateTime property as required using my custom required validator which gets the error message from a resources file (I don't want to have to tell the RequiredAttribute the type of the resource file and the key every time i apply it. That is why I'm making a custom one.) How can i prevent the framework from applying the required attribute to properties of type DateTime and int etc without changing them to nullable. Thanks

  • Naming a typedef for a boost::shared_ptr<const Foo>

    - by Blair Zajac
    Silly question, but say you have class Foo: class Foo { public: typedef boost::shared_ptr<Foo> RcPtr; void non_const_method() {} void const_method() const {} }; Having a const Foo::RcPtr doesn't prevent non-const methods from being invoked on the class, the following will compile: #include <boost/shared_ptr.hpp> int main() { const Foo::RcPtr const_foo_ptr(new Foo); const_foo_ptr->non_const_method(); const_foo_ptr->const_method(); return 0; } But naming a typedef ConstRcPtr implies, to me, that the typedef would be typedef const boost::shared_ptr<Foo> ConstRcPtr; which is not what I'm interested in. An odder name, but maybe more accurate, is RcPtrConst: typedef boost::shared_ptr<const Foo> RcPtrConst; However, Googling for RcPtrConst gets zero hits, so people don't use this as a typedef name :) Does anyone have any other suggestions?

  • How do I stop image spam from being uploaded to my (future) site?

    - by Pete Lacey
    I have in mind an idea for a generally accessible site that needs to allow images to be uploaded. But I'm stymied on how to prevent image spam: porn, ads in image form, etc. Assumptions: I'm assuming that the spammers are clever, even human. I'm skeptical of the efficacy of image analysis software. I do not have the resources to approve all uploads manually. I am willing to spend money on the solution -- within reason. This site will be location-aware, if that helps. How does Flickr do it or imgur? Or do they?

  • Scope of object properties & methods

    - by Anish
    In the article Show love to the object literal, it's said: When we have several scripts in a page, the global variables & functions will get overwritten if their name repeats. One solution is to make the variables as properties & functions as methods of an object, and access them via the object name. But will this prevent the issue of variables getting into the global namespace? <script> var movie = { name: "a", trailer: function(){ //code } }; </script> In the above code which elements gets added to the global namespace? a) Just the object name - movie b) Object name as well as the properties and methods inside it – movie, movie.name, movie.trailer()

  • How to create virtual Environment for users on server

    - by Bhushan Nagaonkar
    I have a web application where users can register them self and then save Java and C++ programs in their account. Programs are saved in a tmp directory like, /tmp -user1 --program1 --program2 -user2 --program1 --program2 So all the users folders are in same "tmp" directory. I want to know how can I proved security by not allowing a user to access files of other users. A user will be executing a java or c++ program in his folder which can be used to read files on the server. How to prevent this? I am new to this thing I don't know how to go about this. The server is Linux server and project is in python using Django. Thank in advance

  • Disabling itemrenderer Hovered state

    - by duder
    My itemrenderer has 2 custom states, no hovered state, and no normal state <s:states> <s:State name="state1" /> <s:State name="state2" /> </s:states> When I initialize it, I force it to go to state2. The problem is that when it's hovered over, it relapses back to the first state state1. It's kind of weird since I don't really have a hovered state. Anyone knows how to prevent this from happening? maybe by somehow disabling the hover effect?

  • Return a dynamic string from std::exception's `what`

    - by Shtééf
    I'm convinced at this point that I should be creating subclasses of std::exception for all my exception throwing needs. Now I'm looking at how to override the what method. The situation that I'm facing, it would be really handy if the string what returns be dynamic. Some pieces of code parse an XML file for example, and adding a position or line number to the error message is useful to me. What I'd like to know: what returns a const char *, which implies any catcher is likely not going to free the string. So I need some other place to store the result, but where would that be? (I need thread-safety.) what also includes throw() in its signature. While I can prevent my what from throwing anything, it seems to me that this method really isn't intended for anything too dynamic. If what is not the right place, then where should I be doing this instead?

  • loading HTML fragments with jQuery

    - by sam
    Hi everybody, I'm very new to jQuery, Ajax and things like these. I've found solutions on how to inject HTML fragments into my site: $(document).ready(function(){ $('a').click(openContent); //binding all anchors to this function }); function openContent(){ var path = $(this).attr('href'); $('#content').load(path); return false; //to prevent browser from loading the single HTML fragment } That works really fine! The problem is, these function won't be executed when clicking on anchors located in the new HTML fragment which were injected right before. So the fragment won't get injected into div, the browser will only load the fragment for itself. Hope there are solutions which aren't that tricky... thanks sam

  • Potential for SQL injection here?

    - by Matt Greer
    This may be a really dumb question but I figure why not... I am using RIA Services with Entity Framework as the back end. I have some places in my app where I accept user input and directly ask RIA Services (and in turn EF and in turn my database) questions using their data. Do any of these layers help prevent security issues or should I scrub my data myself? For example, whenever a new user registers with the app, I call this method: [Query] public IEnumerable<EmailVerificationResult> VerifyUserWithEmailToken(string token) { using (UserService userService = new UserService()) { // token came straight from the user, am I in trouble here passing it directly into // my DomainService, should I verify the data here (or in UserService)? User user = userService.GetUserByEmailVerificationToken(token); ... } } (and whether I should be rolling my own user verification system is another issue altogether, we are in the process of adopting MS's membership framework. I'm more interested in sql injection and RIA services in general)

  • How to assign default values and define unique keys in Entity Framework 4 Designer

    - by csharpnoob
    Hello, I've had a look at the Entity Framework 4. While generating code for the SQL Server 2008 I came to the point where I want to define some default values for some fields. how to define in the designer for a Created DateTime Field the DateTime.Now default value? - Error 54: Default value (DateTime.Now) is not valid for DateTime. The value must be in the form 'yyyy-MM-dd HH:mm:ss.fffZ' how to make for code generation a string Field unique. Like E-Mail or Username can exists only once in the table. I've search alot in the internet and also checked my books Pro Entity Framework 4.0 and Programming Entity Framework. But none of them seems to come up with the default value issue, or using sql commands as default values for database generation. Another thing is, how to prevent on database generation always from droping tables? Instead i want to append non existing fields and keep the data. Thanks for any suggestions.

  • C++ Template Classes Circular Dependency Problem

    We have two classes: template<typename T, typename Size, typename Stack, typename Sparse> class Matrix and template<typename T, typename Size> class Iterator Matrix should be able to return begin and end iterators and Iterator will keep a referrence to the Matrix to access the elements via it's interface. We don't want Iterator to depend on the internal storage of the Matrix to prevent coupling. How can we solve this cyclic dependency problem? (The internal Storage class has the same template parameters as the Matrix class and the same access procedures as the Matrix itself)
