  • Passing along variable inside link works only on first word in multiple-word-variables, why?

    - by Camran
    I have this code below. As you can see I am passing two variables along with the link. The second variabye (category) works whenever it consists of one word, but some categories are two words or more, and then on the receiving php page where I fetch the variable only the first word is fetched. Any ideas? Example: I pass along this: Rims & Tires Only this comes through: Rims $display_table .= "<a href='../ad.php?ad_id=$row[ad_id]&category=$row[category]' target='_parent'>"; Here is how I fetch it in the receiving php file (which the link is to): $cat = $_GET['category']; echo $cat; //displays only first word of multiple word categories. Thanks

  • Get nul value from one ViewController to one ViewController

    - by sovannarith
    I have 2 ViewControllers namely V1 and V2. I want to pass value from V2 to V1 but I get value 0 for countV1 in V1. I saw more questions in stackoverflow but I can't deal with this small problem. I use ARC. In V1 .h file @property(nonatomic,unsafe_unretained) int countV1; .m file @synthesize countV1; In V2 .m file int countV2 = 1; V1 *v1 = [V1 alloc] initWithNibName:@"V1" bundle:nil]; v1.countV1 = countV2;

  • How can I check a user/password combination on an ActiveDirectory without putting the password in a String?

    - by Jean Hominal
    I want to check User/Password combination on a Windows domain. Right now I do it with the following code: bool Login(String username, String password) { var principalContext = new PrincipalContext(ContextType.Domain); principalContext.ValidateCredentials(username, password); } While it works, the thing that bugs me is that I have to put the password in a String in order to use that API; as I am using a SecureString to store the password everywhere else, I would really like to use some way of checking the username / password combination without having to pass the password as a managed System.String. What would be the best way of achieving that?

  • Get path to a file via flash

    - by jeffkolez
    I'm not a flash dev, but I'm turning to it to try and meet a requirement. I'm to allow a user to select a file on their computer, then pass it to my web application. I know it's not possible to do this using Javascript, hence wanting to use flash. First, is this possible? Second, can I get a pointer on how its done? To clarify: I'm just looking for the path to the file. I don't want to upload it.

  • Put specific tds from a table row into edit using jQuery (then update w/ ajax)

    - by bbqsauced
    I'm somewhat new to jQuery, so I could use some help here. This is my issue: I have a php script outputting a dynamic table. Each row has an "edit" button, plus some other fields. Only 3 of those need to be turned into an input box. The edit button should only put that specific row into "edit mode." I got as far as assigning each row a unique class by adding a number to the end of it. I have been able to use jQuery to change all of the rows into edit mode, but I need it to be specific to a row. An example row would have classes like name0, price0, and desc0. The next row would go on to classes name1, price1, and desc1 (for the fields that need changed). How can I reference these values and pass them to jQuery so it processes an event on just those elements?

  • Framework/tool for processing C++ unit tests with numerical output

    - by David Claridge
    Hi, I am working on a C++ application that uses computer vision techniques to identify various types of objects in a sequence of images. The (1000+) images have been hand-classified, so we have an XML file for each image containing a description of where the objects are actually located in the images. I would like to know if there is a testing framework that can understand/graph results from tests that are numeric, in this case some measure of the error in the program's classification of the images, rather than just pass/fail style unit tests. We would like to use something like CDash/CTest for running these automated tests, and viewing over time how improvements to the vision algorithms are causing the images to be more correctly classified. Does anyone know of a tool/framework that can do this?

  • Backbone collection's URL depends on initialize function

    - by egidra
    I have a Backbone collection whose URL depends on the initialize function. When I create an instance of this Backbone collection, I pass in an ID to filter which instances of the model appear. Here is what the collection's code looks like: var GoalUpdateList = Backbone.Collection.extend({ // Reference the Goal Update model model: GoalUpdate, // Do HTTP requests on this endpoint url: "http://localhost:8000/api/v1/goal_update/?goal__id=" + this.goal_id + "&format=json", // Set the goal ID that the goal update list corresponds to initialize: function(goal_id) { this.goal_id = goal_id; console.log(this.goal_id); console.log(this.url); }, }); Of course, this doesn't work. this.goal_id is seen as being undefined. I guess because the URL is set before the initialization function is run.

  • jQuery ajax() and cakePHP urls

    - by Pickledegg
    I'm trying to call the 'tariff' action of my 'countries' controller using jQuery ajax() and pass it a country name in the following format: /countries/tariff/countryname however, with the following code ( set to GET ), it is calling this with the get '?' added: /countries/tariff/?countryname $(document).ready(function(){ $('#CountriesIndexForm select').change(function(){ $.ajax({ type: "GET", url: "/countries/tariff/", data: escape($(this).val()), success: function(html){ $(this).parent().next('div').html(html); } }); }); }); I understand its because the type: is set to GET, but is there a fix for this?

  • image on top of button android

    - by N-AccessDev
    Is it possible to add an image(view) on top of a button (which as a background image)? I'm porting an iOS app to Android and it wasn't a problem on iOS, but I'm wondering if it is the right approach on Android because of layouts. Edit : To clarify, check this screen shot : http://a4.mzstatic.com/us/r1000/062/Purple/v4/7c/4b/cd/7c4bcd53-ba55-94d7-a26c-ce1bfe040003/mza_2736801523527387264.320x480-75.jpg I need to do the bottom left button "carte" (card in french) I need : a button with a background image an image displayed on top of the button which is loaded from internet (a card , there is a lot of different and news cards are added daily, in the screnshot it s "MIDI PASS" ) a text localised on the button , so I cant use Imagebutton class.

  • I'm having a hard time wrapping my head around handling the Activity Lifecycle...

    - by kefs
    So it seems i've created a fatal flaw and coded an app before understanding/handling rotation/lifecycle events.. Currently, all of my code is in onCreate of each activity. I've read a lot of lifecycle tutorials online, including the official dev guide info, but i'm still having an almost unbelievably hard time trying to wrap my head around the rotation/lifecycle events/methods and when to use them correctly. For example, my app currently has an activity that opens the db, inserts a record, then closes the db.. if i rotate my screen on this activity, the data is re-entered into the db. Using the available lifecycle events (onPause(), onResume(), etc..), how would I prevent this db call from happening again? Would I have to pass a variable through the state saying that the db call has been done, and not to do it again? Thanks in advance..

  • How can I find all the supported weights of a Font in Java?

    - by William
    How can I find all the available font weights for a given font in Java? The TextAttribute for font weight lists 11 different weight constants, way more than just Font.PLAIN and Font.BOLD. I'd like to know which ones actually exist for a given font family, so I can make sure I'm only using weights for which a font face exists. The getAttributes() and getAvailableAttributes() methods in Font will only show me whether or not the Font supports the FONT_WEIGHT attribute, not which weight values it supports. If I just pass in a particular value to see what I get back, I don't have any guarantee that I'll get what I asked for. The TextAttribute class says "The values for WEIGHT, WIDTH, and POSTURE are interpolated by the system, which can select the 'nearest available' font or use other techniques to approximate the user's request."

  • c++ Array passing dilemma

    - by Thomas
    Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.

  • Grid computing projects similar to NGrid (thread based)

    - by DivdeAndConquer
    Hello there, first time poster. This is a great place for reading about programming problems. I've been looking at some grid computing projects for .Net/Mono and stumbled upon NGrid. NGrid seems really appealing for grid computing because you simply pass threads to it and there is very little modification you have to make to your code. However, I see that NGrid (http://ngrid.sourceforge.net/?page=overview) is still at version 0.7 and hasn't been updated since May 2008. So, I'm wondering if there are any other grid computing projects that use a similar thread-passing architecture and if anyone has had success using NGrid.

  • Java String to SHA1

    - by AeroDroid
    I'm trying to make a simple String to SHA1 converter in Java and this is what I've got... public static String toSHA1(byte[] convertme) { MessageDigest md = null; try { md = MessageDigest.getInstance("SHA-1"); } catch(NoSuchAlgorithmException e) { e.printStackTrace(); } return new String(md.digest(convertme)); } When I pass it toSHA1("password".getBytes()), I get "[?a?????%l?3~??." I know it's probably a simple encoding fix like UTF-8, but could someone tell me what I should do to get what I want which is "5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8"? Or am I doing this completely wrong? Thanks a lot!

    I have a thread like this public class SMS { class Read implements Runnable { Read(){ Thread th = new Thread(this); th.start(); } @Override public void run() { // TODO Auto-generated method stub while (true){ Variant SMSAPIReturnValue = SMSAPIJava.invoke("ReadSMS"); if (SMSAPIReturnValue.getBoolean()){ String InNumber = SMSAPIJava.getPropertyAsString("MN"); String InMessage = SMSAPIJava.getPropertyAsString("MSG"); } } } } } How do I update the message to another GUI class in the same package(I understand how to put nested class to another package ....). Should I implement a callback function in SMS class? But how? Or should I pass in the Jlabel into the class?

  • How to eliminate authentication on my MVC app that is called from asp.net forms app

    - by Mark Kadlec
    Curious what recommendations anyone has. I have an existing asp.net forms application that does a Forms Authentication and has identity impersonate turned on. The application has a link to a questionnaire that I would like to develop separately in an asp.net MVC application, but I don't want the users to click on the link and be prompted for a username and password, I would like them to be able seamless start filling out the questionnaire. Is there a way to somehow transfer authentication from one .net app to another? I would like to be able to pass stuff like UserRole. What's the best way to do this?

  • jQuery changing css on navigation when div # scrolls into view

    - by Jonny Wood
    I'm looking to recreate the effect used on this site: http://www.brizk.com/ The site uses one large page that scrolls down. As you scroll down and pass different sections the menu navigation on the left changes css class to "current" as the corresponding div comes into view. I presume this can be done with jQuery using $(window).height(); I'm fairly new to jQuery and what I want to write is something like this (in laymans terms): Get height of browser window – if div#content1 is 100px from top and/or 200px from bottom change menu a#link1 to '.current' – else remove .current from all menu a links ... and repeat for 4 different content divs. Can anyone point me in the right direction..? Thanks.

  • Should a company prevent employees from publishing an app in an appstore in their free time?

    - by Tommy
    My company is trying to pass a policy forbidding distribution of any application (even free) in any appstore for all developers. Their reasoning is that "outside work activities create a conflict of interest". They don't want that "you use your spare time to work on your app, and once it takes off you quit your job" (quoting the Head of Development). A few developers (myself included) have already said it was an abusive, pointless and most of all counter-productive policy (developers will actually be demotivated to work here under such control and to be denied of the freedom to distribute their project). Personally, I think it is actually in the interest of the company to promote side projects (even commercial activities, if there is no conflict). I'm also curious, is that common practice?

  • How to change code settings in eclipse

    - by Maven
    Sorry if the question title is confusing. Let me explain further. I am building a Java project with Eclipse. In my Java product I have conditionals that determine what code is included in the product and relies on static final constants for dead stripping. class BuildFlags { public static final boolean SOME_FLAG = true; // Need to set this programmatically } class SomeOtherClass { public void someMethod() { if (BuildFlags.SOME_FLAG) { // flag specific code } } } My question is how can I change BuildFlags.SOME_FLAG (above) so that I can run a special build without changing the source? Is there some way I can pass flags to the jvm (from eclipse) which I can then access to set this flag programatically?

  • passing Perl method results as a reference

    - by arareko
    Some XML::LibXML methods return arrays instead of references to arrays. Instead of doing this: $self->process_items($xml->findnodes('items/item')); I want to do something like: $self->process_items(\$xml->findnodes('items/item')); So that in process_items() I can dereference the original array instead of creating a copy: sub process_items { my ($self, $items) = @_; foreach my $item (@$items) { # do something... } } I can always store the results of findnodes() into an array and then pass the array reference to my own method, but let's say I want to try a reduced version of my code. Is that the correct syntax for passing the method results or should I use something different? Thanks!

  • How to assign a PHP variable that contains a mixed of PHP and html elements?

    - by Rick
    I have a PHP page that contains html and tags and PHP codes and I am using AJAX to manipulate some data and now I need to spit out the response but I am not sure if it is possible to put the mixed content into a string variable to pass through... Is this possible? For example I need to: $response = "<p>some text--<?php echo $something; ?>"; Thanks... To clear things up, I am not trying to send raw PHP code to clientside as that would be silly and won't be evaluated as it is a server side script. I am just looking for a fast way to put everything into a variable without manually re-doing the whole page stripping out the php open and close tags and echos...etc

  • As3 Communicate with C# or Asp.net

    - by brenjt
    I have been looking around for hours trying to find a clear simple solution to my question and have yet to find a good answer. I am trying to do a URL request in flash to my NOPCommerce site. I want to pass a GET value to the my .cs file which i'll then use that value to grab specific information and return it back to flash. How would I set up the C# or asp.net side of things? If anyone could give me an example of what I am looking for I would greatly appreciate it. I don't know if I am supposed to use a .aspx, .cs or .ascx file. Thanks, Brennan

  • Any way to avoid a filesort when order by is different to where clause?

    - by Julian
    I have an incredibly simple query (table type InnoDb) and EXPLAIN says that MySQL must do an extra pass to find out how to retrieve the rows in sorted order. SELECT * FROM `comments` WHERE (commentable_id = 1976) ORDER BY created_at desc LIMIT 0, 5 exact explain output: table select_type type extra possible_keys key key length ref rows comments simple ref using where; using filesort common_lookups common_lookups 5 const 89 commentable_id is indexed. Comments has nothing trick in it, just a content field. The manual suggests that if the order by is different to the where, there is no way filesort can be avoided. http://dev.mysql.com/doc/refman/5.0/en/order-by-optimization.html I also tried order by id as well as it's equivalent but makes no difference, even if I add id as an index (which I understand is not required as id is indexed implicitly in MySQL). thanks in advance for any ideas!

  • How to decide if a parameter is the click event

    - by sameold
    I have a function which can be called by either a click event or directly. When I call it directly, I need pass it a data parameter, so I've defined the function to accept a parameter to account for the direct call with the parameter. function myFunc(param){ } Within the function, I need to differentiate whether the function was called directly or from the click event, so what I thought I could simply check if param is set. If it's set, then the function is called directly. If it's not set, then it's called from the click event. The problem is that a click event by default passes an event object. So even when the function is called by the click event, param won't be null. So is there a way to check whether the param passed is the click event?

  • Best way to force Spring shutdown from a bean?

    - by xcut
    My application uses a Spring DefaultMessageListenerContainer to process incoming messages. The main method of the app already registers a shutdown hook. Question is this: what is the best way to force the application context to shut down? If I throw a RuntimeException in the message listener, it is handled by the container, and not passed on. Is calling System.exit acceptable? Do I pass along the ApplicationContext to every class that needs to shut down, so I can call close() on it?
