  • Skipping one item in the column

    - by zurna
    I created a simple news website. I store both videos and images in IMAGES table. Videos added have videos and images added have images stored in a column called ImagesType. Images and Videos attached to a news is stored in ImagesID column of the NEWS table. My problem occurs when I need to display the first image of a news. i.e. IMAGES table: ImagesID ImagesLgURL ImagesType 1 /FLPM/media/videos/0H7T9C0F.flv videos 2 /FLPM/media/images/8R5D7M8O.jpg images 3 /FLPM/media/images/0E7Q9Z0C.jpg images NEWS table NewsID ImagesID NewsTitle 1 1;2; Street Chic: Paris ERROR 2 3; Paris Runway NO ERROR The following code give me an error with the 2nd news item because the first ImageID stored in the list is not an image but a video. I need to figure out a way to skip the video item and display the next image. I hope I made sense. SQL = "SELECT NEWSID, CATEGORIESID, IMAGESID, NEWSTITLE, NEWSSHORTDESC, NEWSACTIVE, NEWSDATEENTERED" SQL = SQL & " FROM NEWS N" SQL = SQL & " WHERE NEWSACTIVE = 1" SQL = SQL & " ORDER BY NEWSDATEENTERED DESC" Set objNews = objConn.Execute(SQL) Do While intLooper1 <= 3 And Not objNews.EOF IMAGES = Split(Left(objNews("IMAGESID"),Len(objNews("IMAGESID"))-1), ";") SQL = "SELECT ImagesID, ImagesName, ImagesLgURL, ImagesSmURL, ImagesType" SQL = SQL & " FROM IMAGES I" SQL = SQL & " WHERE ImagesID = " & IMAGES(0) & " AND ImagesType = 'images'" Set objLgImage = objConn.Execute(SQL) <div> <a href="?Section=news&SubSection=redirect&NEWSID=<%=objNews("NEWSID")%>"> <img src="<%=objLgImage("ImagesLgURL")%>" alt="<%=objLgImage("ImagesName")%>" /> </a> </div> <% objLgImage.Close Set objLgImage = Nothing intLooper1 = intLooper1 + 1 objNews.MoveNext Loop %>

  • How do I pass a callback function to sqlite3_exec on iOS 5.1?

    - by John Doh
    I am new to both xcode/iOS/Objective-C and sqlite. I am trying to teach myself the basics - and I would like to use the sqlite3 wrapper "sqlite3_exec" for a select query. For some reason, I can't find a simple example anywhere of someone doing this. Basically, the method has a parameter (the third one) for a callback function: int sqlite3_exec( sqlite3*, /* An open database */ const char *sql, /* SQL to be evaluated */ int (*callback)(void*,int,char**,char**), /* Callback function */ void *, /* 1st argument to callback */ char **errmsg /* Error msg written here */ ); That's fine. I'm no stranger to callbacks. However, I just can't seem to get the syntax down right. I took over one of the view controllers in my iPad (iOS 5.1) xcode (4.3) project, and made the changes shown below: #import "SecondViewController.h" #import "sqlite3.h" #import "AppState.h" @interface SecondViewController () @end @implementation SecondViewController - (int)myCallback:(void *)a_parm argc:(int)argc argv:(char **)argv column:(char **)column { return 0; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //grab questionnaire names char *sql = "select * from QST2Main order by [Name]"; char *err = nil; sqlite3 *db = [[AppState sharedManager] getgCn]; sqlite3_exec(db, sql, myCallback, nil, &err); } Essentially, I want to run a query when this view first loads, to store some data for later use. But, XCode doesn't like the "myCallback" usage at the bottom there. It says: Undeclared Use of Identifier 'myCallback.' That method is declared in the header file, and I've even tried making it static. Nothing seems to make this error go away. I know I must be doing something fundamentally wrong here, but for the life of me I can't figure out what - I can't even find other code samples in this area that could help me figure out what I'm missing. Many thanks!

  • Issue with IHttpHandler and relative URLs

    - by vtortola
    Hi, I've developed a IHttpHandler class and I've configured it as verb="*" path="*", so I'm handling all the request with it in an attempt of create my own REST implementation for a test web site that generates the html dynamically. So, when a request for a .css file arrives, I've to do something like context.Response.WriteFile(Server.MapPath(url)) ... same for pictures and so on, I have to response everything myself. My main issue, is when I put relative URLs in the anchors; for example, I have main page with a link like this <a href="page1">Go to Page 1</a> , and in Page 1 I have another link <a href="page2">Go to Page 2</a>. Page 1 and 2 are supposed to be at the same level (http://host/page1 and http://host/page2, but when I click in Go to Page 2, I got this url in the handler: ~/page1/~/page2 ... what is a pain, because I have to do an url = url.SubString(url.LastIndexOf('~')) for clean it, although I feel that there is nothing wrong and this behavior is totally normal. Right now, I can cope with it, but I think that in the future this is gonna bring me some headache. I've tried to set all the links with absolute URLs using the information of context.Request.Url, but it's also a pain :D, so I'd like to know if there is a nicer way to do these kind of things. Don't hesitate in giving me pretty obvious responses because I'm pretty new in web development and probably I'm skipping something basic about URLs, Http and so on. Thanks in advance and kind regards.

  • Selenium onChange not working

    - by tohop
    Hi, I have tried a number of things to try and get Selenium to pick up an 'onchange' event from a drop down menu, none of which has worked. The offending HTML is: <select onchange="doOpperation(this.options[this.selectedIndex]); this.selectedIndex = 0;" name="opps_ondemand" id="opps_ondemand"> <option value="none" id="ondemand">Mark as...</option> <option cmd="blah1" value="add">Something</option> <option cmd="blah2" value="remove">None</option> </select> I have read that Selenium IDE doesn't record some on* events, and so it would be wise to use fireEvent(): $this->click("opps_ondemand"); $this->select("opps_ondemand", "label=Mark as..."); $this->click("//option[@value='add']"); sleep(3); $this->fireEvent("//select[@id='opps_ondemand']", "change"); However, this does not work (with or without the fireEvent). I have also tried using $this->fireEvent("locator", "click"); instead of $this->click("locator"); but this did nothing. Selenium does not complain about these locators not existing so I am assuming it can see the select/option elements fine. The problem seems to be the onChange event. Does anyone know how to resolve this? Thanks.

  • What programming languages do the top tier Universities teach?

    - by Simucal
    I'm constantly being inundated with articles and people talking about how most of today's Universities are nothing more than Java vocational schools churning out mediocre programmer after mediocre programmer. Our very own Joel Spolsky has his famous article, "The Perils of Java Schools." Similarly, Alan Kay, a famous Computer Scientist (and SO member) has said this in the past: "I fear — as far as I can tell — that most undergraduate degrees in computer science these days are basically Java vocational training." - Alan Kay (link) If the languages being taught by the schools are considered such a contributing factor to the quality of the school's program then I'm curious what languages do the "top-tier" computer science schools teach (MIT, Carnegie Mellon, Stanford, etc)? If the average school is performing so poorly due in large part the languages (or lack of) that they teach then what languages do the supposed "good" cs programs teach that differentiate them? If you can, provide the name of the school you attended, followed by a list of the languages they use throughout their coursework. Edit: Shog-9 asks why I don't get this information directly from the schools websites themselves. I would, but many schools websites don't discuss the languages they use in their class descriptions. Quite a few will say, "using high-level languages we will...", without elaborating on which languages they use. So, we should be able to get a pretty accurate list of languages taught at various well known institutions from the various SO members who have attended at them.

  • Lua Alien Module - Trouble using WriteProcessMemory function, unsure on types (unit32)

    - by jefferysanders
    require "alien" --the address im trying to edit in the Mahjong game on Win7 local SCOREREF = 0x0744D554 --this should give me full access to the process local ACCESS = 0x001F0FFF --this is my process ID for my open window of Mahjong local PID = 1136 --function to open proc local op = alien.Kernel32.OpenProcess op:types{ ret = "pointer", abi = "stdcall"; "int", "int", "int"} --function to write to proc mem local wm = alien.Kernel32.WriteProcessMemory wm:types{ ret = "long", abi = "stdcall"; "pointer", "pointer", "pointer", "long", "pointer" } local pRef = op(ACCESS, true, PID) local buf = alien.buffer("99") -- ptr,uint32,byte arr (no idea what to make this),int, ptr print( wm( pRef, SCOREREF, buf, 4, nil)) --prints 1 if success, 0 if failed So that is my code. I am not even sure if I have the types set correctly. I am completely lost and need some guidance. I really wish there was more online help/documentation for alien, it confuses my poor brain. What utterly baffles me is that it WriteProcessMemory will sometimes complete successfully (though it does nothing at all, to my knowledge) and will also sometimes fail to complete successfully. As I've stated, my brain hurts. Any help appreciated.

  • No test coverage files generated for Unit Test bundle in Xcode

    - by John Gallagher
    The Problem I've got a Cocoa project on the desktop and I'm using Xcode 3.2.1 on Snow Leopard 10.6.2. I want to generate code coverage files for my Unit Test Target in Xcode. What I've Tried As articles like this one suggest, I've adjusted the build settings to: “Generate Test Coverage Files” checked “Instrument Program Flow” checked “-lgcov” added to “Other Linker Flags” I've also set the Run Script section of the test target to have the following: # Run the unit tests in this test bundle. "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" # Run gcov on the framework getting tested if [ "${CONFIGURATION}" = 'Coverage' ]; then FRAMEWORK_NAME=LapsusInterpretationEngine FRAMEWORK_OBJ_DIR=${OBJROOT}/${FRAMEWORK_NAME}.build/${CONFIGURATION}/EngineTests.build/Objects-normal/${NATIVE_ARCH} mkdir -p coverage pushd coverage find ${OBJROOT} -name *.gcda -exec gcov -o ${FRAMEWORK_OBJ_DIR} {} \; popd fi Since my Framework name is LapsusInterpretationEngine but my target is named EngineTests, I put this directly into the FRAMEWORK_OBJ_DIR but this didn't seem to help. I've tried cleaning before building. I've made sure all the above build settings apply to both the Unit Test Target and the Application Target. What I Get No .gcda or .gcno files anywhere in the build directory I'm using. I point CoverStory to the Objects-normal directory in my builds folder and it complains that there's nothing there for it to read. I must be doing something really obvious wrong. Anyone any ideas? I have tried the "EngineTests.build" directory being ${FRAMEWORK_NAME} and this gives the same results.

  • Custom ConfigurationSection: CallbackValidator called with empty string

    - by Paolo Tedesco
    I am writing a custom configuration section, and I would like to validate a configuration property with a callback, like in this example: using System; using System.Configuration; class CustomSection : ConfigurationSection { [ConfigurationProperty("stringValue", IsRequired = false)] [CallbackValidator(Type = typeof(CustomSection), CallbackMethodName = "ValidateString")] public string StringValue { get { return (string)this["stringValue"]; } set { this["stringValue"] = value; } } public static void ValidateString(object value) { if (string.IsNullOrEmpty((string)value)) { throw new ArgumentException("string must not be empty."); } } } class Program { static void Main(string[] args) { CustomSection cfg = (CustomSection)ConfigurationManager.GetSection("customSection"); Console.WriteLine(cfg.StringValue); } } And my App.config file looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="customSection" type="CustomSection, config-section"/> </configSections> <customSection stringValue="lorem ipsum"/> </configuration> My problem is that when the ValidateString function is called, the value parameter is always an empty string, and therefore the validation fails. If i just remove the validator, the string value is correctly initialized to the value in the configuration file. What am I missing? EDIT I discovered that actually the validation function is being called twice: the first time with the default value of the property, which is an empty string if nothing is specified, the second time with the real value read from the configuration file. Is there a way to modify this behavior?

  • Safari Extension Questions

    - by Rob Wilkerson
    I'm in the process of building my first Safari extension--a very simple one--but I've run into a couple of problems. The extension boils down to a single, injected script that attempts to bypass the native feed handler and redirect to an http:// URI. My issues so far are twofold: The "whitelist" isn't working the way I'd expect. Since all feeds are shown under the "feed://" protocol, I've tried to capture that in the whitelist as "feed://*/*" (with nothing in the blacklist), but I end up in a request loop that I can't understand. If I set blacklist values of "http://*/*" and "https://*/*", everything works as expected. I can't figure out how to access my settings from my injected script. The script creates a beforeload event handler, but can't access my settings using the safari.extension.settings path indicated in the documentation. I haven't found anything in Apple's documentation to indicate that settings shouldn't be available from my script. Since extensions are such a new feature, even Google returns limited relevant results and most of those are from the official documentation. What am I missing? Thanks.

  • Chain of DataBinding

    - by Neir0
    Hello I am trying to do follow DataBinding Property -> DependencyProperty -> Property But i have trouble. For example, We have simple class with two properties implements INotifyPropertyChanged: public class MyClass : INotifyPropertyChanged { private string _num1; public string Num1 { get { return _num1; } set { _num1 = value; OnPropertyChanged("Num1"); } } private string _num2; public string Num2 { get { return _num2; } set { _num2 = value; OnPropertyChanged("Num2"); } } public event PropertyChangedEventHandler PropertyChanged; public void OnPropertyChanged(string e) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) handler(this, new PropertyChangedEventArgs(e)); } } And TextBlock declared in xaml: <TextBlock Name="tb" FontSize="20" Foreground="Red" Text="qwerqwerwqer" /> Now lets trying to bind Num1 to tb.Text: private MyClass _myClass = new MyClass(); public MainWindow() { InitializeComponent(); Binding binding1 = new Binding("Num1") { Source = _myClass, Mode = BindingMode.OneWay }; Binding binding2 = new Binding("Num2") { Source = _myClass, Mode = BindingMode.TwoWay }; tb.SetBinding(TextBlock.TextProperty, binding1); //tb.SetBinding(TextBlock.TextProperty, binding2); var timer = new Timer(500) {Enabled = true,}; timer.Elapsed += (sender, args) => _myClass.Num1 += "a"; timer.Start(); } It works well. But if we uncomment this string tb.SetBinding(TextBlock.TextProperty, binding2); then TextBlock display nothing. DataBinding doesn't work! How can i to do what i want?

  • CCLabelAtlas setString doesn't update label

    - by JonnyFunFun
    Hello! I have a CCLabelAtlas that I have on a layer to display the current score within my game...the problem that I am having with it is that it does not update when I use [scoreLabel setString:]. Here's how I have it laid out: In the header: @interface GameScene : CCLayer { ... CCLabelAtlas* scoreLabel; } And in the init: scoreLabel = [[CCLabelAtlas alloc] initWithString:@"0" charMapFile:@"scoreCharMap.png" itemWidth:6 itemHeight:8 startCharMap:'.']; [scoreLabel setPosition:ccp(105, 414)]; [self addChild:scoreLabel z: 6]; scoreCharMap.png is a custom map that includes ./0123456789 of my desired font. When the score is changed, I attempt to do this to get the label to update with the current score: NSString* str = [[NSString alloc] initWithFormat:@"%d", [[GameRunner sharedInstance] currentScore]]; [scoreLabel setString: str]; [str release]; [scoreLabel draw]; Problem is that it doesn't ever update - it just sits there and displays 0. I know for a fact due to breakpoints and debugging that setString is being called, and that the string that it should be displaying is correct - but it just doesn't update. Hard-coding the value and saying [scoreLabel setString:@"1234"] does nothing, either. What am I doing wrong here? I am using Cocos2d 0.99 - thanks in advance!

  • how to create Java Application and query about OWL using SPARQL/Jena and how to do it on local/remot

    - by user323889
    I want to create simple application using Java Jena and SPARQL ,that insert, delete , update and query the OWL/RDF data I worked on protege to create the ontology and noticed SPARQL in it but I want to use SPARQL using java and jena ... 1) I saw this thread and I knew how to use SPARQL with jena (after http)stackoverflow.com/questions/2267333/using-jena-to-create-a-sparql-query-on-dbpedia it did work with me .. but I want my own ontology to work .. I mean to upload it to server or to work on localhost or whatever ... 2) SPARQL doesn't support operations like update or insert .. but querying is there any other languages/methods that support these operations ? or I should created it manually in java in each application ... 3) how can I upload my ontology and I prefer something related to protege ? because I tried this which got bug : (after http )semweb.krasu.ru/protege2joseki/ and this (which gave me lot of issues) (after http and wwwdot)joseki.org/ nothing work .. 4) RDF-store ... is for just RDF ? because I am working on OWL files .. I mean for example using MySQL as RDF-store .. would it work for OWL concept ?

  • Testing warnings with doctest

    - by Eli Courtwright
    I'd like to use doctests to test the presence of certain warnings. For example, suppose I have the following module: from warnings import warn class Foo(object): """ Instantiating Foo always gives a warning: >>> foo = Foo() testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) >>> """ def __init__(self): warn("Boo!", UserWarning) If I run python -m doctest testdocs.py to run the doctest in my class and make sure that the warning is printed, I get: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) ********************************************************************** File "testdocs.py", line 7, in testdocs.Foo Failed example: foo = Foo() Expected: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) Got nothing ********************************************************************** 1 items had failures: 1 of 1 in testdocs.Foo ***Test Failed*** 1 failures. It looks like the warning is getting printed but not captured or noticed by doctest. I'm guessing that this is because warnings are printed to sys.stderr instead of sys.stdout. But this happens even when I say sys.stderr = sys.stdout at the end of my module. So is there any way to use doctests to test for warnings? I can find no mention of this one way or the other in the documentation or in my Google searching.

  • Memory mapped files and "soft" page faults. Unavoidable?

    - by Robert Oschler
    I have two applications (processes) running under Windows XP that share data via a memory mapped file. Despite all my efforts to eliminate per iteration memory allocations, I still get about 10 soft page faults per data transfer. I've tried every flag there is in CreateFileMapping() and CreateFileView() and it still happens. I'm beginning to wonder if it's just the way memory mapped files work. If anyone there knows the O/S implementation details behind memory mapped files I would appreciate comments on the following theory: If two processes share a memory mapped file and one process writes to it while another reads it, then the O/S marks the pages written to as invalid. When the other process goes to read the memory areas that now belong to invalidated pages, this causes a soft page fault (by design) and the O/S knows to reload the invalidated page. Also, the number of soft page faults is therefore directly proportional to the size of the data write. My experiments seem to bear out the above theory. When I share data I write one contiguous block of data. In other words, the entire shared memory area is overwritten each time. If I make the block bigger the number of soft page faults goes up correspondingly. So, if my theory is true, there is nothing I can do to eliminate the soft page faults short of not using memory mapped files because that is how they work (using soft page faults to maintain page consistency). What is ironic is that I chose to use a memory mapped file instead of a TCP socket connection because I thought it would be more efficient. Note, if the soft page faults are harmless please note that. I've heard that at some point if the number is excessive, the system's performance can be marred. If soft page faults intrinsically are not significantly harmful then if anyone has any guidelines as to what number per second is "excessive" I'd like to hear that. Thanks.

  • Follow tab's url in jquery ui tabs

    - by Aakash Chakravarthy
    Hello, I have jquery tabs like <ul id="tabsList"> <li><a href="#tab-1">Name 1</a></li> <li><a href="#tab-2">Name 2</a></li> <li><a href="http://www.google.com/">Name 3</a></li> </ul> <div id="tab-1">content 1</div> <div id="tab-2">content 2</div> the first two tabs load the respective divs. But the third one should go to google.com, instead it does nothing. It just adds http://example.com/index.html#ui-tabs-[object Object] to the url. I am developing a wordpress plugin and the admin page needs a tab interface. I tested this in a local server and not working update: i don't want to load google.com inside the page. It should open the webpage in new tab/window like ordinary links do.

  • How can I effectively test against the Windows API?

    - by Billy ONeal
    I'm still having issues justifying TDD to myself. As I have mentioned in other questions, 90% of the code I write does absolutely nothing but Call some Windows API functions and Print out the data returned from said functions. The time spent coming up with the fake data that the code needs to process under TDD is incredible -- I literally spend 5 times as much time coming up with the example data as I would spend just writing application code. Part of this problem is that often I'm programming against APIs with which I have little experience, which forces me to write small applications that show me how the real API behaves so that I can write effective fakes/mocks on top of that API. Writing implementation first is the opposite of TDD, but in this case it is unavoidable: I do not know how the real API behaves, so how on earth am I going to be able to create a fake implementation of the API without playing with it? I have read several books on the subject, including Kent Beck's Test Driven Development, By Example, and Michael Feathers' Working Effectively with Legacy Code, which seem to be gospel for TDD fanatics. Feathers' book comes close in the way it describes breaking out dependencies, but even then, the examples provided have one thing in common: The program under test obtains input from other parts of the program under test. My programs do not follow that pattern. Instead, the only input to the program itself is the system upon which it runs. How can one effectively employ TDD on such a project?

  • Inconsistent get_class_methods vs method_exists when using UTF8 characters in PHP code

    - by coma
    I have this class in a UTF-8 encoded file called EnUTF8.Class.php: class EnUTF8 { public function ñññ() { return 'ñññ()'; } } and in another UTF-8 encoded file: require_once('EnUTF8.Class.php'); require_once('OneBuggy.Class.php'); $utf8 = new EnUTF8(); //$buggy = new OneBuggy(); echo (method_exists($utf8, 'ñññ')) ?

UPDATED: Well, after a long debugging time I found this in OneBuggy.Class.php constructor: setlocale (LC_ALL, "es_ES@euro", "es_ES", "esp"); so I did... //setlocale (LC_ALL, "es_ES@euro", "es_ES", "esp"); and now it works but why?.

  • Big sinatra problems

    - by Joel M.
    Hi, So I'm having huge trouble with sinatra. Here's what I have: require 'dm-core' DataMapper.setup(:default, ENV['DATABASE_URL'] || 'sqlite3://my.db') class Something include DataMapper::Resource property :id, Serial property :thing, Text property :run_in, Integer property :added_at, DateTime property :to, String def schedule cronify(self.thing+" to "+self.to, "http://url"+self.id.to_s, self.run_in) end def notify text(self.thing, self.to) end end Something.auto_upgrade! The cronify method works. I tested it in irb. Also, the schedule instance method works, I tested it in the console. However, it doesn't work in the route, even though it works in the console. post '/add' do @something = Something.create(blah) #this works fine @something.schedule #this works fine in the console; not in the route. end I've tried everything, from @something.create(blah).schedule (which also works fine in the console, but not in the route), to defining the method cronify inside the sinatra helpers, and even calling cronify directly on the route. Nothing works on the route. What am I doing wrong?

  • Non RBAC User Roles and Permissions System: checking the user's City

    - by micha12
    We are currently designing a User Roles and Permissions System in our web application (ASP.NET), and it seems that we have several cases that do no fit within the classical Role-Based Access Control (RBAC). I will post several questions, each devoted to a particular case, this being the first post. We have the following case: not to allow a user view a certain page if the user lives in a particular city. This is a simple case that is coded in the following way: if (User.City == “Moscow”) // Allow the user to view the page. else // Do not allow the user to view this page. Though this case is very simple and straightforward, it has nothing to do with the RBAC. On StackOverflow, someone called this an Attribute-based Access Control. Under the classical RBAC, it seems that this case should be designed like this: introduce a permission “City where the person lives”, this permission will have a property City. Then create a role, add a permission of type “City = Moscow” to it and the assign the role to the user. Looks extremely cumbersome. The question is whether it is acceptable to introduce such non-RBAC approaches to our permissions system – does that break the design or not? This might seem a primitive question, but we found that most applications use pure RBAC, and we started to think that we might be doing something wrong. Thank you.

  • JsonParseException on Valid JSON

    - by user2909602
    I am having an issue calling a RESTful service from my client code. I have written the RESTful service using CXF/Jackson, deployed to localhost, and tested using RESTClient successfully. Below is a snippet of the service code: @POST @Produces("application/json") @Consumes("application/json") @Path("/set/mood") public Response setMood(MoodMeter mm) { this.getMmDAO().insert(mm); return Response.ok().entity(mm).build(); } The model class and dao work successfully and the service itself works fine using RESTClient. However, when I attempt to call this service from Java Script, I get the error below on the server side: Caused by: org.codehaus.jackson.JsonParseException: Unexpected character ('m' (code 109)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') I have copied the client side code below. To make sure it has nothing to do with the JSON data itself, I used a valid JSON string (which works using RESTClient, JSON.parse() method, and JSONLint) in the vars 'json' (string) and 'jsonData' (JSON). Below is the Java Script code: var json = '{"mood_value":8,"mood_comments":"new comments","user_id":5,"point":{"latitude":37.292929,"longitude":38.0323323},"created_dtm":1381546869260}'; var jsonData = JSON.parse(json); $.ajax({ url: 'http://localhost:8080/moodmeter/app/service/set/mood', dataType: 'json', data: jsonData, type: "POST", contentType: "application/json" }); I've seen the JsonParseException a number of times on other threads, but in this case the JSON itself appears to be valid (and tested). Any thoughts are appreciated.

  • Having trouble adding jquery to charisma

    I am trying to add some jquery to this Charisma admin panel and have been having nothing but trouble. I am trying to add it to the charisma.js file. This is what I am adding // add multiple select / deselect functionality $("#selectall").click(function () { $('.checkbox').attr('checked', this.checked); }); // if all checkbox are selected, check the selectall checkbox // and viceversa $(".checkbox").click(function(){ if($(".checkbox").length == $(".checkbox:checked").length) { $("#selectall").attr("checked", "checked"); } else { $("#selectall").removeAttr("checked"); } }); I have tried this code wrapped in the anonymous $(function(){ as well as without, and I have inserted it into both $(document).ready(function(){ and docReady() as well as in the head of my code but I am not really "trained" on jquery so I am a bit lost as to what I am doing wrong. My class and div tags are correct for the code, as I have checked them several times for misspellings. I am not sure what I am doing wrong. Is there a better "check" all code I can use here, or am I just putting this all in the wrong place? UPDATE: I think the actual code may be working, I cannot tell, after I click the select all box it seems that I have to click the other boxes 3 times to get the check mark back into the box, so it seems like it is having trouble actually showing that the box is marked. This may be a problem with styling, but I don't know how to correct it.

  • Problem with custom Equality and GetHashCode in a mutable object

    - by Shimmy
    Hello! I am using Entity Framework in my application. I implemented with the partial class of an entity the IEquatable<T> interface: Partial Class Address : Implements IEquatable(Of Address) 'Other part generated Public Overloads Function Equals(ByVal other As Address) As Boolean _ Implements System.IEquatable(Of Address).Equals If ReferenceEquals(Me, other) Then Return True Return AddressId = other.AddressId End Function Public Overrides Function Equals(ByVal obj As Object) As Boolean If obj Is Nothing Then Return MyBase.Equals(obj) If TypeOf obj Is Address Then Return Equals(DirectCast(obj, Address)) Else Return False End Function Public Overrides Function GetHashCode() As Integer Return AddressId.GetHashCode End Function End Class Now in my code I use it this way: Sub Main() Using e As New CompleteKitchenEntities Dim job = e.Job.FirstOrDefault Dim address As New Address() job.Addresses.Add(address) Dim contains1 = job.Addresses.Contains(address) 'True e.SaveChanges() Dim contains2 = job.Addresses.Contains(address) 'False 'The problem is that I can't remove it: Dim removed = job.Addresses.Remoeve(address) 'False End Using End Sub Note (I checked in the debugger visualizer) that the EntityCollection class stores its entities in HashSet so it has to do with the GetHashCode function, I want it to depend on the ID so entities are compared by their IDs. The problem is that when I hit save, the ID changes from 0 to its db value. So the question is how can I have an equatable object, being properly hashed. Please help me find what's wrong in the GetHashCode function (by ID) and what can I change to make it work. Thanks a lot.

  • WPF: Same line drawn different?

    - by stefan.at.wpf
    Hello, I have a canvas and in it I'm drawing some lines: for (int i = 1; i >= 100; i++) { // Line LineGeometry line = new LineGeometry(); line.StartPoint = new Point(i * 100, 0); line.EndPoint = new Point(i * 100, 100 * 100); // Path Path myPath = new Path(); myPath.Stroke = Brushes.Black; myPath.StrokeThickness = 1; // Add to canvas myPath.Data = line; canvas1.Children.Add(myPath); } Well, nothing special, but it makes problems - the lines are drawn different! The canvas is inside a scrollviewer, the following image shows different positions of the canvas, however the lines should look the same? Hell, how is this possible? The code above is the only code I've written by hand and it's the only content in the canvas. Anyone knows why this happens and how to prevent this? Thank you very much!

  • Bash Array Problem

    - by Deepak Prasanna
    I wrote a bash script which tries to find a process and run the process if it had stopped. This is the script. #!/bin/bash process=thin path=/home/deepak/abc/ initiate=thin start -d process_id=`ps -ef | pgrep $process | wc -m` if [ "$process_id" -gt "0" ]; then echo "The process process is running!!" else cd $path $initiate echo "Oops the process has stopped" fi This worked fine and I thought of using arrays so that i can form a loop use this script to check multiple processes. So I modified my script like this #!/bin/bash process[1]=thin path[1]=/home/deepak/abc/ initiate[1]=thin start -d process_id=`ps -ef | pgrep $process[1] | wc -m` if [ "$process_id" -gt "0" ]; then echo "Hurray the process ${process[1]} is running!!" else cd ${path[1]} ${initiate[1]} echo "Oops the process has stopped" echo "Continue your coffee, the process has been stated again! ;)" fi I get this error if i run this script. DontWorry.sh: 2: process[1]=thin: not found DontWorry.sh: 3: path[1]=/home/deepak/abc/: not found DontWorry.sh: 4: initiate[1]=thin start -d: not found I googled to find any solution for this, most them insisted to use "#!/bin/bash" instead of "#!/bin/sh". I tried both but nothing worked. What am i missing?

  • Firefox extension development firefox4

    - by Jesus Ramos
    So I've been working on updating old extensions for use with FF4 and Gecko 2 but I am having some issues where I am getting an error that says, classID missing or incorrect for component.... Has anyone else had a similar issue or know of how to get around this? function jsshellClient() { this.classDescription = "sdConnector JavaScript Shell Service"; this.classID = Components.ID("{54f7f162-35d9-524d-9021-965a3ba86366}"); this.contractID = "@activestate.com/SDService?type=jsshell;1" this._xpcom_categories = [{category: "sd-service", entry: "jsshell"}]; this.name = "jsshell"; this.prefs = Components.classes["@mozilla.org/preferences-service;1"] .getService(Components.interfaces.nsIPrefService) .getBranch("sdconnector.jsshell."); this.enabled = this.prefs.getBoolPref("enabled"); this.port = this.prefs.getIntPref("port"); this.loopbackOnly = this.prefs.getBoolPref("loopbackOnly"); this.backlog = this.prefs.getIntPref("backlog"); } jsshellClient.prototype = new session(); jsshellClient.prototype.constructor = jsshellClient; When calling generateNSGetFactory on the prototype for this it gives an error in the Error Console in FF4 complaining about the classID. I'm pretty sure that nothing else is using the same GUID so I don't see the problem.
