  • Access event.target in IE8 unobstrusive Javascript

    - by Mirko
    The following function gets the target element in a dropdown menu: function getTarget(evt){ var targetElement = null; //if it is a standard browser if (typeof evt.target != 'undefined'){ targetElement = evt.target; } //otherwise it is IE then adapt syntax else{ targetElement = evt.srcElement; } //return id of element when hovering over or if (targetElement.nodeName.toLowerCase() == 'li'){ return targetElement; } else if (targetElement.parentNode.nodeName.toLowerCase() == 'li'){ return targetElement.parentNode; } else{ return targetElement; } Needless to say, it works in Firefox, Chrome, Safari and Opera but it does not in IE8 (and I guess in previous versions as well). When I try to debug it with IE8 I get the error "Member not Found" on the line: targetElement = evt.srcElement; along with other subsequent errors, but I think this is the key line. Any help will be appreciated.

  • PostgreSQL - CREATE INDEX

    - by mocopera
    Hi! I'm working with PostgreSQL to create some data types written in C. For example, I have: typedef struct Point3D { char id[50]; double x; double y; double z; } Point3D; The input and output functions are working properly. But the problem is the following: Every id of Point3D must be unique (and can be NULL), so I have decided to create an unique index on this field id, but is that possible? I'm thinking in something like this: create unique index test_point3d_idx on test_point3d (( getID(columname) )); where getID returns the field ID of columname. But I need to implement getID and I am really blocked. Any advice?

  • Attempting to connect to a CORBA Service using corbaloc url

    - by Megasaur
    String[] orbargs= {}; org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(orbargs, null); org.omg.CORBA.Object cobj = orb.string_to_object("corbaloc:iiop:10.1.1.200:6969/OurServiceHelper"); _OurServiceHelper cpsh = _OurServiceHelperHelper.narrow(cobj); // Get's stuck cpsh.ourMethod(); That narrow just hangs. My service is setup to run on a static port. And we know it works since we usually look it up through the NamingService. What am I doing wrong?

    - by Yegor
    I have a simple Flowplayer playlist. First one plays a short clip, which then cuts off, and an image is displayed. Is there a way to make the image clickable? here is what I have: <a style="display:block;width:640px;height:360px" id="player"> </a> <script> flowplayer("player", "../flowplayer-3.1.5.swf", { playlist: [ {url: 'http://e1h13.simplecdn.net/flowplayer/flowplayer.flv', duration: 10}, {url: 'http://www.domain.com/image.jpg', duration: 100000}, ], plugins: { controls: null } }); </script> If there is another way of doing this, Im all ears. I need a video to play for 10 seconds (or entirely, since the file is gonna be 10 seconds long), and then display some text + a URL.

  • Starting activity from packageinfo

    - by Nyan Lynn Htun
    Is there a way run an intent from packageinfo? I've been searching and I don't find it. I tried like that Intent i = new Intent(); i.setAction(Intent.ACTION_MAIN); i.addCategory(Intent.CATEGORY_LAUNCHER); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); i.setComponent(new ComponentName(p.applicationInfo.packageName,p.applicationInfo.name)); startActivity(i); but it doesn't work because [p.applicationInfo.name] is always null.

  • WPF: change DataTemples according to Value

    - by Kave
    I have a class called Cell with two properties. One is called Value of type int? And the other is called Candidates of type ObservableCollection during the initialization I am utilizing a DataTemplateSelector to choose between two datatemplates for two different scenarios. If the Value property has a value then template A should be used to present the Cell class. However if the Value property is null Then template B should be used to present the Cell class. While this works perfectly fine during the initialization however during the runtime the templates don't change any more when the value of the Value property actually changes. Is the approach of using DataTemplateSelector the wrong approach to change DataTemplates dynamically? What would you recommend I should do? Many thanks,

  • Ambiguous Generic restriction T:class vs T:struct

    - by Maslow
    This code generates a compiler error that the member is already defined with the same parameter types. private T GetProperty<T>(Func<Settings, T> GetFunc) where T:class { try { return GetFunc(Properties.Settings.Default); } catch (Exception exception) { SettingReadException(this,exception); return null; } } private TNullable? GetProperty<TNullable>(Func<Settings, TNullable> GetFunc) where TNullable : struct { try { return GetFunc(Properties.Settings.Default); } catch (Exception ex) { SettingReadException(this, ex); return new Nullable<TNullable>(); } } Is there a clean work around?

  • C# - Do you use "var"?

    - by Paul Stovell
    C# 3.0 introduces implicitly typed variables, aka the "var" keyword. var daysInAWeek = 7; var paul = FindPerson("Paul"); var result = null as IPerson; Others have asked about what it does or what the problems with it are: http://stackoverflow.com/questions/527685/anonymous-types-vs-local-variables-when-should-one-be-used http://stackoverflow.com/questions/209199/whats-the-point-of-the-var-keyword http://stackoverflow.com/questions/41479/use-of-var-keyword-in-c I am interested in some numbers - do you use it? If so, how do you use it? I never use var (and I never use anonymous types) I only use var for anonymous types I only use var where the type is obvious I use var all the time!

  • NHibernate Projections to retrieve a Collection?

    - by Simon Söderman
    I´m having some trouble retrieving a collection of strings in a projection: say that I have the following classes public class WorkSet { public Guid Id { get; set; } public string Title { get; set; } public ISet<string> PartTitles { get; protected set; } } public class Work { public Guid Id { get; set; } public WorkSet WorkSet { get; set; } //a bunch of other properties } I then have a list of Work ids I want to retrieve WorkSet.Title, WorkSet.PartTitles and Id for. My tought was to do something like this: var works = Session.CreateCriteria<Work>() .Add(Restrictions.In("Id", hitIds)) .CreateAlias("WorkSet", "WorkSet") .SetProjection( Projections.ProjectionList() .Add(Projections.Id()) .Add(Projections.Property("WorkSet.Title")) .Add(Projections.Property("WorkSet.PartTitles"))) .List(); The Id and Title loads up just fine, but the PartTitles returns null. Suggestions please!

  • Validate Canadian Postal Code Regex

    - by Alex Block
    I have a script written in JavaScript to Validate Canadian Postal Codes using Regex, however it does not seem to be working. Here is the script: If statement: if (myform.zip.value == "" || myform.zip.value == null || myform.zip.value == "Postal Code" || myform.zip.value.length < 12 ) { alert("Please fill in field Postal Code. You should only enter 7 characters"); myform.zip.focus(); return false; } Function: function okNumber(myform) { var regex = /^[ABCEGHJKLMNPRSTVXY]{1}\d{1}[A-Z]{1} *\d{1}[A-Z]{1}\d{1}$/; if (regex.test(myform.zip.value) == false) { alert("Input Valid Postal Code"); myform.zip.focus(); return false; } return true; }

  • Malloc to a CGPoint Pointer throwing EXC_BAD_ACCESS when accessing

    - by kdbdallas
    I am trying to use a snippet of code from a Apple programming guide, and I am getting a EXC_BAD_ACCESS when trying to pass a pointer to a function, right after doing a malloc. (For Reference: iPhone Application Programming Guide: Event Handling - Listing 3-6) The code in question is really simple: CFMutableDictionaryRef touchBeginPoints; UITouch *touch; .... CGPoint *point = (CGPoint *)CFDictionaryGetValue(touchBeginPoints, touch); if (point == NULL) { point = (CGPoint *)malloc(sizeof(CGPoint)); CFDictionarySetValue(touchBeginPoints, touch, point); } Now when the program goes into the if statement it assigns the 'output' of malloc into the point variable/pointer. Then when it tries to pass point into the CFDictionarySetValue function it crashes the application with: Program received signal: “EXC_BAD_ACCESS”. Someone suggested not doing the malloc and pass the point var/pointer as: &point, however that still gave me a EXC_BAD_ACCESS. What I am (and it looks like Apple) doing wrong??? Thanks in advance.

  • How to transform a vector<int> into a string?

    - by Legend
    I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?

  • Can't get a LiveFolder to launch my activity like it should

    - by Felix
    I was able to create a ContentProvider for a LiveFolder, but I can't seem to be able to create my intents correctly, so it always gives "Application is not installed on your phone" errors when clicking on items inside the folder. My Activity is defined like so, in the manifest: <activity android:name=".MyActivity"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> Then, I create the intents I place in the LiveFolders.INTENT column like this: i = new Intent(); i.setAction(null); i.setClassName("my.package.here", ".MyActivity"); I don't get why this is not working. Maybe I'm making some stupid mistake, but please point me in the right direction.

  • .NET MVC - Storing database result during single page result?

    - by ropstah
    Fairly simple issue which is solved in PHP by using a static variable. private static $pages; public function Pages() { if($pages == null) { $pages = new PageCollection(); $pages->findAll(); } } Everywhere in my code I use Pages()::someFindFunction() to make sure the results are fetched only once, and I use that same collection. I want the same in my .NET MVC application: use something like: <%=MySite.Pages.findById(1).Title%> In the code below, if I use a private variable, or if I use a public class with shared variables (doesn't matter) they are both persisted during the entire application. I want them to load the same way PHP does, once per request. Now where do I store the .NET equivalent of private static $pages, so that the code below works? //what to do with $pages?? Public Module MySite Public Function Pages() As PageCollection If $pages Is Nothing Then $pages.loadAll() End If Return $pages End Function End Module

  • Bash: using commands as parameters (specificly cd, dirname and find)

    - by sixtyfootersdude
    This command and output: % find . -name file.xml 2> /dev/null ./a/d/file.xml % So this command and output: % dirname `find . -name file.xml 2> /dev/null` ./a/d % So you would expect that this command: % cd `dirname `find . -name file.xml 2> /dev/null`` Would change the current directory to ./a/d. Strangely this does not work. When I type cd ./a/d. The directory change works. However I cannot find out why the above does not work...

  • Change LINQ2SQL property in partial class?

    - by Fermin
    Hi, I have a table in my LINQ2SQL diagram with a column called DayOfWeek in table JourneyBooking. The designer.cs has the definition of this as: [Column(Storage="_DayOfWeek", DbType="TinyInt NOT NULL")] public int DayOfWeek { get { return this._DayOfWeek; } set { if ((this._DayOfWeek != value)) { this.OnDayOfWeekChanging(value); this.SendPropertyChanging(); this._DayOfWeek = value; this.SendPropertyChanged("DayOfWeek"); this.OnDayOfWeekChanged(); } } } I have a partial class for the JourneyBooking class. Is it possible to extend/overwrite the above DayOfWeek property with my own property? The issue I am having is that DayOfWeek is 0-6 in C# but 1-7 in SQL, so I was thinking that I could overwrite the DayOfWeek property to subtract or add 1 depending on whether it was a get or set, is this possible or would I need to re-write all of the above code in my partial class?

  • Using an EJB inside a JAX-RS resource class in RestEasy?

    - by Laird Nelson
    I would like to have the following kind of resource class work when deployed under RestEasy in JBoss 6: @Path("Something") public class Foo { @EJB private SomeService service @GET public Object frobnicate() { assert service != null; // JBoss blows up here return result; } } Two questions: It is a limitation of RestEasy, not of the Java EE specification, right, that RestEasy can't inject anything annotated with @EJB? What have people done to work around this limitation? My developers are about to surge forward with hard-coded JNDI lookups (e.g. context.lookup(someHardCodedNameHere)) because no one can find a workaround to this specification violation at the present time. I really want to avoid this. Lastly, I've looked at using CDI, but the story here isn't much better as RestEasy and CDI still aren't talking to each other. Thanks in advance for any pointers.

  • Producer Consumer Issue with Core Data

    - by Mugunth Kumar
    I've a Core Data application. In the producer thread, I pull data from a web service and store it in my object and call save. My consumer object is a table view controller that displays the same. However, the app crashes and I get NSFetchedResultsController Error: expected to find object (entity: FeedEntry; id: 0xf46f40 ; data: ) in section (null) for deletion on the console. When I debug it, everything works fine. So I understood that it's like a race issue. How is these kind of problem solved? What's the best way to design a producer-consumer app with core-data?

  • std::string == operator not working

    Hello, I've been using std::string's == operator for years on windows and linux. Now I am compiling one of my libraries on linux, it uses == heavily. On linux the following function fails, because the == returns false even when the strings are equal (case sensitive wise equal) const Data* DataBase::getDataByName( const std::string& name ) const { for ( unsigned int i = 0 ; i < m_dataList.getNum() ; i++ ) { if ( m_dataList.get(i)->getName() == name ) { return m_dataList.get(i); } } return NULL; } The getName() method is declared as follows virtual const std::string& getName() const; I am building with gcc 4.4.1 and libstdc++44-4.4.1. Any ideas? it looks perfectly valid to me. Paul

I need a criteria to get all the elements after i make sort on nullable inner object.

  • Is it safe to convert a mysqlpp::sql_blob to a std::string?

    - by Runcible
    I'm grabbing some binary data out of my MySQL database. It comes out as a mysqlpp::sql_blob type. It just so happens that this BLOB is a serialized Google Protobuf. I need to de-serialize it so that I can access it normally. This gives a compile error, since ParseFromString() is not intended for mysqlpp:sql_blob types: protobuf.ParseFromString( record.data ); However, if I force the cast, it compiles OK: protobuf.ParseFromString( (std::string) record.data ); Is this safe? I'm particularly worried because of this snippet from the mysqlpp documentation: "Because C++ strings handle binary data just fine, you might think you can use std::string instead of sql_blob, but the current design of String converts to std::string via a C string. As a result, the BLOB data is truncated at the first embedded null character during population of the SSQLS. There’s no way to fix that without completely redesigning either String or the SSQLS mechanism." Thanks for your assistance!
