  • JSF/HTML - Add a Java applet to web page programmatically.

    - by Ben
    Theres a web page I'm making which content is very dynamic and so I'm building it from inside the backing bean. I would like to add a Java applet to the web page but I could not find the JSF component type to correspond to the <applet> tag. So My questions are - What is the JSF component type for an applet? How did you find it? (For similar future searches) Thanks! P.S - Just to be clear. An example: <h:PanelGroup> would be HtmlPanelGroup as a java object.

  • When is a Cocoa callback given controll?

    - by Kaspa
    Hi, I've been searching around the web for an answer to this one, but was unable to find an answer, on the other side I think it's something quite common thus there is a possibility I'm missing some keywords here. Anyhow, the problem is as follows: When is control given to a callback function in ObjC (iPhone)? Does it happen after control is given to a high up in the hierarchy class responsible for the runloop? Can it occur in the middle of another function call being executed? As an example, let's take the NSURLConnection, we don't know or can't predict when it's going to call didReceiveResponse or the other callback methods, can it be the case that didReceiveResponse get's called when I'm in the middle of another function? (highly doubt that but was unable to find information on callbacks wating for the end of the run loop) Cheers, Kaspa

  • Intersection between sets containing different types of variables

    - by Gacek
    Let's assume we have two collections: List<double> values List<SomePoint> points where SomePoint is a type containing three coordinates of the point: SomePoint { double X; double Y; double Z; } Now, I would like to perform the intersection between these two collections to find out for which points in points the z coordinate is eqal to one of the elements of values I created something like that: HashSet<double> hash = new HashSet<double>(points.Select(p=>p.Z)); hash.IntersectWith(values); var result = new List<SomePoints>(); foreach(var h in hash) result.Add(points.Find(p => p.Z == h)); But it won't return these points for which there is the same Z value, but different X and Y. Is there any better way to do it?

  • Is there any way to perform pre-/post-switch commands using TortoiseSVN?

    - by Steve
    We need to perform some tasks when switching from one Subversion branch to another using TortoiseSVN. Is there any way to, say, call a batch file before and after the switch? The only thing I can find are pre-/post-update and commit hooks, but none of those get executed when switching between branches. EDIT: I am looking for client-side hooks. TortoiseSVN has client-side hook scripts for pre-/post-update and commit, but nothing (that I can find) for pre-/post-switch. Initially, I thought adding hooks for client-side pre-/post-update would be executed when switching between branches, but this does not seem to be the case.

  • Finding vars from dynamically created namespaces in clojure

    - by Tom Crayford
    The following test fails: (ns clojure_refactoring.rename-fn-test (:use clojure.test)) (deftest test-fn-location (in-ns 'refactoring-test-fn-rename) (clojure.core/refer-clojure) (defn a [b] (inc b)) (in-ns 'clojure_refactoring.rename-fn-test) (is (not= (find-var 'refactoring-test-fn-rename/a) nil)) (remove-ns 'refactoring-test-fn-rename)) That is, find-var (of a var I've just created, in a namespace I've just create) returns nil. This behaviour doesn't happen at the repl, where typing out the steps of the test works just fine. Am I doing something wrong, or is this just something that doesn't work in clojure right now?

  • How do I search git history for a disappeared line?

    - by skiphoppy
    I need to search the history of a file in a git repository to find a line that is gone. The commit message will not have any relevant text to search on. What command do I use? Further details: this is the history of my todo list out of our non-stellar task tracking software. I've been keeping it for two years because there's just not enough information kept for me in the software. My commit messages usually have only the task ids, unfortunately, and what I need to do is find a closed task by subject, not by number. Yes, the real solution is better task tracking software, but that is completely out of my hands.

  • How can I tell cpan the change the target for the moduleinstallation?

    - by sid_com
    Hello! When I installed perl from the source the first nice surprise was that without doing something all module installed from now on were available to the new perl. Since I didn't find one module on cpan that comes with my OS I have to use for some scripts the onboard-perl. For one of these scripts I would like to install Text::Format or Text::Autoformat (didn't find the docu for that module on cpan). My question: how can I tell cpan to install the module this one time for the OS-distro-perl?

  • Change a registry value in vb.net

    - by mhofer
    Hello, I have searched a lot to find a solution for my problem, but I can't find any specific solution. I need to change a value which is stored under HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME. It is not possible to use .NET's registry functions, since they have drastic restrictions. The following snippet should solve my problem: Dim regKey As RegistryKey Dim ver As Decimal regKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME", True) regKey.SetValue("IP", "192.168.10.15:18500") regKey.Close() Unfortunately, I get a NullReferenceExeption when I try to set the value. What should I do? I have imported Microsoft.Win32 and RegistryKey doesn't accept any constructor... cheers mike

  • Get PropertyInfo from property instead of name

    - by Sam
    Say, for example, I've got this simple class: public class MyClass { public String MyProperty { get; set; } } The way to get the PropertyInfo for MyProperty would be: typeof(MyClass).GetProperty("MyProperty"); This sucks! Why? Easy: it will break as soon as I change the Name of the Property, it needs a lot of dedicated tests to find every location where a property is used like this, refactoring and usage trees are unable to find these kinds of access. Ain't there any way to properly access a property? Something, that is validated on compile time? I'd love a command like this: propertyof(MyClass.MyProperty);

  • How to bind WPF TreeView to a List<Drink> programmatically?

    - by Joan Venge
    So I am very new to WPF and trying to bind or assign a list of Drink values to a wpf treeview, but don't know how to do that, and find it really hard to find anything online that just shows stuff without using xaml. struct Drink { public string Name { get; private set; } public int Popularity { get; private set; } public Drink ( string name, int popularity ) : this ( ) { this.Name = name; this.Popularity = popularity; } } List<Drink> coldDrinks = new List<Drink> ( ){ new Drink ( "Water", 1 ), new Drink ( "Fanta", 2 ), new Drink ( "Sprite", 3 ), new Drink ( "Coke", 4 ), new Drink ( "Milk", 5 ) }; } } How can I do this in code? For example: treeview1.DataItems = coldDrinks; and everything shows up in the treeview.

  • Filtering across two ManyToMany fields

    - by KVISH
    I have a User model and an Event model. I have the following for both: class Event(models.Model): ... timestamp = models.DateTimeField() organization_map = models.ManyToManyField(Organization) class User(AuthUser): ... subscribed_orgs = models.ManyToManyField('Organization') I want to find all events that were created in a certain timeframe and find the users who are subscribed to those organizations. I know how to write SQL for this (it's very easy), but whats the pythonic way of doing this using Django ORM? I'm trying as per below: orgs = Organization.objects.all() events = Event.objects.filter(timestamp__gt=min_time) # Min time is the time I want to start from events = events.filter(organization_map__in=orgs) But from there, how do I map to users who have that organization as a subscription? I'm trying to map it like so: users = User.objects.filter(subscribed_orgs__in=...

  • How do I build (get/download) time.h library?

    - by coffeenet
    I am trying to build a project on Linux via Makefile. I keep getting cannot find <sys/time.h> error. I asked around, and I was told that my project doesn't have access to library folders. Therefore, I am trying to solve this problem by using the time library locally inside my project's folder. I am very new to Linux. So, please forgive my question if it sounds naive. I found this, but I don't know what files I need, and how to build the library. http://sourceware.org/git/?p=glibc.git;a=tree;f=time;h=c950c5d4dd90541e8f3c7e1649fcde4aead989bb;hb=master Where can I find the time.h library/package? How do I build the library?

  • Symfony form's i18n and add_empty

    - by David
    I have this widget: $this->setWidget('slug', new sfWidgetFormDoctrineChoice(array('model' => 'MyTable', 'method' => 'myMethod', 'key_method' => 'myMethod', 'add_empty' => 'Select option'))); Ok, what should I do to translate the "Select option"? I can't use the __() helper inside the form, and adding that string into my XLIFF file doesn't translate it automatically. If it can't be done, what workaround should I implement? I can't find any way, and neither can't find any tip in the official documentation. Thanks!

  • How do I view the parameters of currently running procs in SQL Server 2008

    - by Pez
    I am trying to troubleshoot an issue that is popping up on our new SQL Server. While viewing the running processes (sp_who2) I can't tell what parameters a proc was started with. I can find the name of the proc using: DBCC INPUTBUFFER (spid) I can even find some additional info, but I can't see a way to show the parameters. (http://sqlserverpedia.com/blog/sql-server-bloggers/sql-server-%E2%80%93-get-last-running-query-based-on-spid/) I know I can see the parameters if I do a trace, but that doesn't help in this case.

  • How do you keep Cocoa controllers from getting too big?

    - by zoul
    Hello! Do you have some tricks or techniques to break Cocoa controller classes into smaller chunks? I find that whatever I do the controllers end up being one of the more complicated classes in my design. The basic stuff is simple, but once I have several pop-overs or action sheets running, things get uncomfortably complex. It's not that bad, but still I would like to refactor the code into several standalone chunks. I thought about categories, but the code is not that independent (a lot of times it needs to tap into viewWillAppear, for example) and I find that I spend a long time fighting the compiler. I also thought about adding functionality in layers using inheritance, but that feels like a hack.

  • Pattern for unidirectional has_many join?

    - by Kris
    It occurred to me that if I have a has_many join, where the foreign model does not have a belongs_to, and so the join is one way, then I don't actually need a foreign key. We could have a column, category_ids, which stores a marshaled Array of IDs which we can pass to find. So here is an untested example: class page < AR def categories Category.find(self.category_ids) end def categories<<(category) # get id and append to category_ids save! end def category_ids @cat_ids ||= Marshal.load(read_attribute(:category_ids)) rescue [] end def category_ids=(ids) @cat_ids = ids write_attribute(:category_ids, ids) end end page.category_ids = [1,4,12,3] page.categories = Array of Category Is there accepted pattern for this already? Is it common or just not worth the effort?

  • Whats the difference between a C++ and a Cocoa Project in Xcode?

    - by david
    I need to work with TagLib for my project. I've created a framework (and I tried using it as a lib) but the compiler cannot find #include < strings on compiling (No such file or Directory). I've created a test C++ project and it #includes < strings just fine. I've looked at the project settings and I cannot find a difference between them. But the standard cocoa projects obviously so not have the search path set to include C++ libraries (Or am I completely getting it wrong?). I've searched for a solution but no one else seems to have run into this problem.

  • C++: need indexed set

    - by user231536
    I need an indexed associative container that operates as follows: initially empty, size=0. when I add a new element to it, it places it at index [size], very similar to a vector's push_back. It increments the size and returns the index of the newly added element. if the element already exists, it returns the index where it occurs. Set seems the ideal data structure for this but I don't see any thing like getting an index from a find operation. Find on a set returns an iterator to the element. Will taking the difference with set.begin() be the correct thing to do in this situation?
