  • Set text based on Form <select> value

    - by danit
    I have the following <select> in a form: <select style="width: 100px; text-align: center;"> <option value="email">Email</option> <option value="telephone">Phone</option> </select> The default option is Email so the following <input> is show: <p class="email_form">Please supply your Email Address</p> <input onfocus="if(!this._haschanged){this.value=''};this._haschanged=true;" style="width: 270px" type="email" name="email" id="email" value="[email protected]"> However if they choose telephone I want to change the above to ask for a telephone number?

  • Having difficulty add a custom icon to a JFrame

    - by Oliver
    Hi, I have been trying to change the icon in the frame. I have virtually tried everything: The icon is 16x16 which is the right size ....doesn't work I've trying PNG,GIF and JPG formats none of them work. Tried different way of setting the icon....doesn't work. I've tried relative (local paths) e.g. "icon.gif" and absolute paths e.g. "c:\work\java\icon.gif" ...doesn't work Here is my code and see if you can figure it out Thanks Oli import javax.swing.*; public class androidDriver { public static void main(String[] args) throws IOException { JFrame f = new JFrame("Android Data Viewer"); f.setResizable(false); f.setSize(300,300); f.setLocationRelativeTo(null); f.setVisible(true); f.setIconImage(new ImageIcon("androidIcon2.gif").getImage()); } }

  • XCode project complains about missing files if a linked framework contains private headers

    - by darklight
    My Problem is this: My framework contains public and private headers - the public headers import private headers in the framework My app that links against this framework imports public headers Now when I compile it, XCode complains about missing files (the private headers that are indirectly imported via the frameworks public headers). I read somewhere on stackoverflow that I should do this: "In the public header file use @class to include other interfaces and use #import in the implementation file (.m)." I find this solution pretty unsatisfying - you have to use it for circular dependencies, too. Is there any better way to keep my headers private?

  • Signals and Variables in VHDL (order) - Problem

    - by Morano88
    I have a signal and this signal is a bitvector (Z). The length of the bitvector depends on an input n, it is not fixed. In order to find the length, I have to do some computations. Can I define a signal after defining the variables ? It is giving me errors when I do that. It is working fine If I keep the signal before the variables (that what is showing below) .. but I don't want that .. the length of Z depends on the computations of the variables. What is the solution ? library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity BSD_Full_Comp is Generic (n:integer:=8); Port(X, Y : inout std_logic_vector(n-1 downto 0); FZ : out std_logic_vector(1 downto 0)); end BSD_Full_Comp; architecture struct of BSD_Full_Comp is Component BSD_BitComparator Port ( Ai_1 : inout STD_LOGIC; Ai_0 : inout STD_LOGIC; Bi_1 : inout STD_LOGIC; Bi_0 : inout STD_LOGIC; S1 : out STD_LOGIC; S0 : out STD_LOGIC ); END Component; Signal Z : std_logic_vector(2*n-3 downto 0); begin ass : process Variable length : integer := n; Variable pow : integer :=0 ; Variable ZS : integer :=0; begin while length /= 0 loop length := length/2; pow := pow+1; end loop; length := 2 ** pow; ZS := length - n; wait; end process; end struct;

  • Why boost property tree write_json saves everything as string? Is it possible to change that?

    - by pprzemek
    I'm trying to serialize using boost property tree write_json, it saves everything as strings, it's not that data are wrong, but I need to cast them explicitly every time and I want to use them somewhere else. (like in python or other C++ json (non boost) library) here is some sample code and what I get depending on locale: boost::property_tree::ptree root, arr, elem1, elem2; elem1.put<int>("key0", 0); elem1.put<bool>("key1", true); elem2.put<float>("key2", 2.2f); elem2.put<double>("key3", 3.3); arr.push_back( std::make_pair("", elem1) ); arr.push_back( std::make_pair("", elem2) ); root.put_child("path1.path2", arr); std::stringstream ss; write_json(ss, root); std::string my_string_to_send_somewhare_else = ss.str(); and my_string_to_send_somewhere_else is sth. like this: { "path1" : { "path2" : [ { "key0" : "0", "key1" : "true" }, { "key2" : "2.2", "key3" : "3.3" } ] } } Is there anyway to save them as the values, like: "key1" : true or "key2" : 2.2 ?

  • Declarative JDOQL vs Single-String JDOQL : performance

    - by DrDro
    When querying with JDOQL is there a performance difference between using the declarative version and the Single-String version: Example from the JDOQL doc: //Declarative JDOQL : Query q = pm.newQuery(org.jpox.Person.class, "lastName == \"Jones\" && age < age_limit"); q.declareParameters("double age_limit"); List results = (List)q.execute(20.0); //Single-String JDOQL : Query q = pm.newQuery("SELECT FROM org.jpox.Person WHERE lastName == \"Jones\"" + " && age < :age_limit PARAMETERS double age_limit"); List results = (List)q.execute(20.0); Other then performance, are there any reasons for which one is better to use then the other or is it just about the one with which we feel more comfortable.

  • HQL query for entity with max value

    - by Rob
    I have a Hibernate entity that looks like this (accessors ommitted for brevity): @Entity @Table(name="FeatureList_Version") @SecondaryTable(name="FeatureList", pkJoinColumns=@PrimaryKeyJoinColumn(name="FeatureList_Key")) public class FeatureList implements Serializable { @Id @Column(name="FeatureList_Version_Key") private String key; @Column(name="Name",table="FeatureList") private String name; @Column(name="VERSION") private Integer version; } I want to craft an HQL query that retrieves the most up to date version of a FeatureList. The following query sort of works: Select f.name, max(f.version) from FeatureList f group by f.name The trouble is that won't populate the key field, which I need to contain the key of the record with the highest version number for the given FeatureList. If I add f.key in the select it won't work because it's not in the group by or an aggregate and if I put it in the group by the whole thing stops working and it just gives me every version as a separate entity. So, can anybody help?

  • How to combine elements of a list

    - by Addie
    I'm working in c#. I have a sorted List of structures. The structure has a DateTime object which stores month and year and an integer which stores a value. The list is sorted by date. I need to traverse the list and combine it so that I only have one instance of the structure per date. For example: My initial list would look like this: { (Apr10, 3), (Apr10, 2), (Apr10, -3), (May10, 1), (May10, 1), (May10, -3), (Jun10, 3) } The resulting list should look like this: { (Apr10, 2), (May10, -1), (Jun10, 3) } I'm looking for a simple / efficient solution. The struct is: class CurrentTrade { public DateTime date; public int dwBuy; } The list is: private List<CurrentTrade> FillList

  • Intent.getInt() doesn't work on ICS, but works on JB

    - by ObAt
    I use this code to send parameters when I start a new Activity: Intent inputForm = new Intent(getActivity(), InputForm.class); Bundle b = new Bundle(); b.putInt("item", Integer.parseInt(mItem.id)); //Your id inputForm.putExtras(b); //Put your id to your next Intent startActivity(inputForm); And I use this code for reading the parameters in the inputForm Activity: Bundle b = getIntent().getExtras(); if (b != null) { int value = b.getInt("item"); ID = value; } Toast.makeText(getApplication(), "MIJN ID:" + Integer.toString(ID), Toast.LENGTH_LONG).show(); When I run this code on my Samsung Tab 10.1 GT-P7510 ID is alsways 0, when I run the same code on my Galaxy S3 with JB the code just works fine. Can someone help me? Thanks in advance, ObAt

  • Why did this work? ( php dot notation )

    - by Daniel
    Hi, I was writing some php code after a long sint doing ruby and I accidently wrote this: [root@ip-10-160-47-98 test]# cat run.php <?php class MyTest { public function run() { var_dump(this.test); } } $object = new MyTest(); $object->run(); [root@ip-10-160-47-98 test]# php run.php string(8) "thistest" [root@ip-10-160-47-98 test]# Now, this.test should have been $this-test, but the compiler was actually happy to let this run. Does anyone know how (this.test) got converted into a string "thistest"? Compiled and run on php 5.3.2 amazon instance ami-e32273a6 (CentOS 5.4) -daniel

  • Extending Throwable in Java

    - by polygenelubricants
    Java lets you create an entirely new subtype of Throwable, e.g: public class FlyingPig extends Throwable { ... } Now, very rarely, I may do something like this: throw new FlyingPig("Oink!"); and of course elsewhere: try { ... } catch (FlyingPig porky) { ... } My questions are: Is this a bad idea? And if so, why? What could've been done to prevent this subtyping if it is a bad idea? Since it's not preventable (as far as I know), what catastrophies could result? If this isn't such a bad idea, why not? How can you make something useful out of the fact that you can extends Throwable?

  • Providing localized error messages for non-attributed model validation in ASP.Net MVC 2?

    - by Lance McNearney
    I'm using the DataAnnotations attributes along with ASP.Net MVC 2 to provide model validation for my ViewModels: public class ExamplePersonViewModel { [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(Resources.Validation))] [StringLength(128, ErrorMessageResourceName = "StringLength", ErrorMessageResourceType = typeof(Resources.Validation))] [DataType(DataType.Text)] public string Name { get; set; } [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(Resources.Validation))] [DataType(DataType.Text)] public int Age { get; set; } } This seems to work as expected (although it's very verbose). The problem I have is that there are behind-the-scenes model validations being performed that are not tied to any specific attribute. An example of this in the above model is that the Age property needs to be an int. If you try to enter a non-integer value on the form, it will error with the following (non-localized) message: The field Age must be a number. How can these non-attribute validation messages be localized? Is there a full list of these messages available so I can make sure they are all localized?

  • The cost of nested methods

    - by Palimondo
    In Scala one might define methods inside other methods. This limits their scope of use to inside of definition block. I use them to improve readability of code that uses several higher-order functions. In contrast to anonymous function literals, this allows me to give them meaningful names before passing them on. For example: class AggregatedPerson extends HashSet[PersonRecord] { def mostFrequentName: String = { type NameCount = (String, Int) def moreFirst(a: NameCount, b: NameCount) = a._2 > b._2 def countOccurrences(nameGroup: (String, List[PersonRecord])) = (nameGroup._1, nameGroup._2.size) iterator.toList.groupBy(_.fullName). map(countOccurrences).iterator.toList. sortWith(moreFirst).head._1 } } Is there any runtime cost because of the nested method definition I should be aware of? Does the answer differ for closures?

  • Strategy for storing and displaying form dropdown data for provinces, states, prefixes?

    - by meder
    I'm currently migrating from a class that stores lists of countries, states & provinces in the form of arrays to using Zend's Locale data in the form of ldml xml files. These ldml files provide localised lists of countries, currencies, languages - so I'm not exactly sure where I should store US States, ( Canadian Provinces ), Prefixes - I was thinking possibly just create a generic xml file and store it in the same directory as the ldml files, but having doubts because it wouldn't really be localised as I'd store it in English. Should I go with storing it in a generic xml file, or possibly update each of the locale files ( eg en.xml ) and append them? The latter is probably not worth the work, which is why I'm swaying towards just a general.xml or dropdown-data.xml. As for generating dropdown options, I suppose I could just say, grab all US states, append the array with Canadian provinces, and append that with an 'Other' option - does this seem like the right way to go about?

    - by Morteza M.
    Hi everybody here, I want to use mootools and SqueezBox class to handle a request to a RESTful service. I don't want to use any server-side script. I am using AJAX. I send a request to the following url using GET method. http://www.idevcenter.com/api/v1/links/links-upcoming.json but I receive a 404 error. Is it because cross-site scripting? here is my code: SqueezeBox.initialize({handler:'url',ajaxOptions:{method:'GET'}}); $('a.modal').addEvent('click',function(e){ new Event(e).stop(); SqueezeBox.fromElement($('a.modal')); }); In Firebug console, sometimes 'aborted' is shown and sometimes '404'.what is wrong with that?

  • compile Boost as static Universal binary lib

  • How to more effectively debug PHP code in the vein JavaScript with Firebug or XCode?

    - by racl101
    Hi everyone, I'm kind of a newbie with PHP so please bear with me. I would like to know if there was an effective way of debugging PHP code so that I don't have to have debugging messages display on the browser. For example, I find var_dump and print_r functions to be excellent for debugging variables, function calls and arrays respectively. The problem is I have been asked to debug code on a live site (no dev site, I know it is a horrible practice but this is not my project from the start.) So I would like to know what core function or php library or whatever else it is that I could use to log debugging calls in to log that I can check so I don't have to send debugging calls to the browser on a live site? I like the way you can use the console.log function in JavaScript code and check it in Firebug or the Webkit Console and I also like like the console window in Xcode and I was wondering if there was some similar tool for PHP debugging. Any extra info and pearls of wisdom would be greatly appreciated. Thanks, racl101.

  • Equality Comparison with Multiple Instances/IEqualityComparer problems in LINQ

    - by Stacey
    This is similar to my last question; but from a different angle. http://stackoverflow.com/questions/2792393/see-if-item-exists-once-in-enumerable-linq Given the following set of items, and lists containing them... Item 1 Item 2 Item 3 Item 4 Item 5 class Item { string Name { get; set; } } List<Item> available = new List<Item>() { Item 1 Item 1 Item 2 Item 3 Item 5 } List<Item> selected = new List<Item>() { Item 1 Item 2 Item 3 } I need to make a third List that has everything from "available", except what is in "selected". However 'Item 1' is in 'available' twice, but only in 'selected' once. Since they are instances of the same item, I am having trouble figuring out the appropriate logic to accomodate this. The final array should look like... List<Item> selectable = new List<Item>() { Item 1 Item5 }

  • How to transfer url parameters to repoze custom predicate checkers

    - by user281521
    I would like to create a repoze custom predicate checker that is capable to access url parameters and validate something. But I would like to use allow_only to set this permission checker in all the controller's scope. Something like: class MyController(BaseController): allow_only = All(not_anonymous(msg=l_(u'You must be logged on')), my_custom_predicate(msg=l_(u'something wrong'))) def index(self, **kw): return dict() then, my_custom_predicate should check the url paramters for every request in every MyController method, and do whatever it do. The problem is just that: how to allow my_custom_predicate to check the url parameters, using it in that way I wrote above.

  • How to correctly pop a modeless dialog from console using MFC

    - by Vertilka
    I need to create a console application that has a main() function and pop a modeless dialog, so the console can still work in parallel to the modeless dialog (do other work, like communicating with the modeless dialog). Whatever i tried, i could only pop a modal dialog. (where the console is in hold till the modal dialog close itself). When switching to modeless dialog using Create() and ShowWindow() the dialog is displayed without its controls and it freeze / block (you can see the hourglass cursor). 1) i tried to pop the modeless dialog from the main() function 2) i tried to pop the modeless dialog from the InitInstance() of a CWinApp derived class In all cases the modeless dialog freeze / block. I believe this is a one line solution. TNX,Vertilka
