• best approach to do jsf form validation

  - by gurupriyan.e

  If I have many input controls in a form (There are separate validators for each of these input controls - like required,length and so on ) , there is a command button which submits the form and calls an action method. The requirement is - though the input control values are , say , individually okay - the combination of these values should be okay to process them together after the form submission - Where do i place the code to validate them together? 1) Can i add a custom validator for the command button and validate the combination together? like validate(FacesContext arg0, UIComponent arg1, Object value) but even then I will not have values of the other input controls except for the command button's/component's value right ? 2) can i do the validation of the combination in the action method and add validation messages using FacesMessage ? or do you suggest any other approach? Thanks for your time.

• How to implement async pattern in windows forms application?

  - by Alkersan

  I'm using an MVC pattern in winforms application. I need to call remote service asynchronously. So On some event in View I invoke corresponding Presenter method. In Presenter I call BeginInvoke method of service. But to View must be updated only in Main Thread. I could actualy point CallBack to some function in View, and update it`s controls state, but this conflicts with MVP pattern - View must not be responsible for data it carries. This callback function must be in Presenter. But how then invoke View in Main Thread?

• C++. How to define template parameter of type T for class A when class T needs a type A template parameter?

  - by jaybny

  Executor class has template of type P and it takes a P object in constructor. Algo class has a template E and also has a static variable of type E. Processor class has template T and a collection of Ts. Question how can I define Executor< Processor<Algo> > and Algo<Executor> ? Is this possible? I see no way to defining this, its kind of an "infinite recursive template argument" See code. template <class T> class Processor { map<string,T> ts; void Process(string str, int i) { ts[str].Do(i); } } template <class P> class Executor { Proc &p; Executor(P &p) : Proc(p) {} void Foo(string str, int i) { p.Process(str,i); } Execute(string str) { } } template <class E> class Algo { static E e; void Do(int i) {} void Foo() { e.Execute("xxx"); } } main () { typedef Processor<Algo> PALGO; // invalid typedef Executor<PALGO> EPALGO; typedef Algo<EPALGO> AEPALGO; Executor<PALGO> executor(PALGO()); AEPALGO::E = executor; }

• What's the proper way to use sqlite at xCode?

  - by Elliot Chen

  Hi, Experts: Can you please give some suggestions on sqlite using at xcode? Within my application, I use a sqlite DB to store all local data. Two methods can be used to retrieve those data during running time. 1, Load all the data into memory at initialization stage. (More memory used, less DB open/close operation needed) 2, Read corresponding records when necessary, free the occupied memory after using. (Good habit for memory using, but much DB open/close operations needs). I prefer to use method 2, but not sure whether too many DB opening/closing operations could affect app's efficiency. Or do you think I can 'upgrade' method 2 by opening DB when app launches and closing DB when app quits? Thanks for your suggestions very much!

• Java DAO caching

  - by santiagobasulto

  I'm developing a medium Java app, and i'm facing a small problem due to my lack of experience. I've a custom DAO, which gets "Article" objects from the Database. I've the Article class, and the DAO has a method called getArticle(int id), this method returns an Article. The Article has a Category object, and I'm using lazy loading. So, when I request for an article's category (Article a = new Article(); a.getCategory();) the Article class gets the Category from the DAO and then returns it. I'm now thinking to cache it, so when I request multiple times to an article's category, the database is only queried one time. My question is: where should I put that cache? I can put it on the Article class (in the DTO), or I can put it on the DAO class. What do you say?

• Need help in translating code from C to Java.

  - by Vuntic

  From this article. Here's the code: float InvSqrt(float x){ // line 0 float xhalf = 0.5f * x; int i = *(int*)&x; // store floating-point bits in integer i = 0x5f3759d5 - (i >> 1); // initial guess for Newton's method x = *(float*)&i; // convert new bits into float x = x*(1.5f - xhalf*x*x); // One round of Newton's method return x; } ...I can't even tell if that's C or C++. [okay apparently it's C, thanks] Could someone translate it to Java for me, please? It's (only, I hope) lines 2 and 4 that are confusing me.

• jQuery variables and scope

  - by Peuge

  I am writing a jQuery plugin and am running into a few problems with regard to variables. For example I have the following skeleton structure for my plugin, which is going to act on a textbox. In my init function I want to set a variable and bind a keypress event to my textbox. That keypress event needs to call another function, in which I need the variable. Is this possible? (function($){ var methods = { init : function(options){ return this.each(function(){ var $this = $(this); var someVar = 'somevar'; $this.keypress(function(event){ //I want to call my customFunction }); }); }, customFunction : function(){ //I am wanting to access 'someVar' here }; $.fn.mynamespace = function(method){ //handle which method to call here }; })(jQuery); Many thanks in advance.

• Best direction for displaying game graphics in C# App

  - by Mike Webb

  I am making a small game as sort of a test project, nothing major. I just started and am working on the graphics piece, but I'm not sure the best way to draw the graphics to the screen. It is going to be sort of like the old Zelda, so pretty simple using bitmaps and such. I started thinking that I could just paint to a Picture Box control using Drawing.Graphics with the Handle from the control, but this seems cumbersome. I'm also not sure if I can use double buffering with this method either. I looked at XNA, but for now I wanted to use a simple method to display everything. So, my question. Using the current C# windows controls and framework, what is the best approach to displaying game graphics (i.e. Picture Box, build a custom control, etc.)

• How do I render a partial to a string from within a filter attached to a controller

  - by Tristan Havelick

  I have some code I need to use in multiple controllers in a rails 1.0 application (I can't, for strange reasons upgrade to a newer rails). I've extracted the relevant code into a filer object, and I'm using the around_filter construct to execute it. Before the extract, I was using the method render_to_string() to get the contents of a rendered partial into a string. However, this method is protected, so I am unable to access it from within my Filter object. As a workaround, I tried adding this to my ApplicationController: def render_to_string(*a) super(*a) end this seems to have remedied the protection level issue, but now I get the error: Can only render or redirect once per action When no such error occurred before the extraction. Why? Is there a different approach I should take here?

• Passing data between Castle Windsor's Interceptors

  - by Nhím H? Báo

  I'm adopting Castle Windsor for my WCF project and feel really amazed about this. However, I'm having a scenario that I don't really know if Castle Windsor supports. For example I have the following chained Interceptors Interceptor 1 > Interceptor 2 > Interceptor 3 > Interceptor 4 > Real method Interceptor 1 returns some data and I want that to be available in Interceptor 2 Interceptor 2 in turn does it work and returns the data that I want to make avaialbe in the 3,4, interceptor. The real case scenario is that we're having a WCF service, Interceptor 1 will parse the request header into a Header object(username, password, etc.). The latter interceptors and real method will ultilize this Header object. I know that I can use Session variable to transport data, but is it a built-in, more elegant, more reliable way to handle this?

I want to stop user to submit if the city is not selected.

• navigation between screens Iphone programming

  - by Sephy

  Hi, I don't know if my question will be clear or not, but i'm starting basic stuff with iphone programming, and i'm trying to understand how to go from a screen to another. lets say i have a screen with a "next page" button and another page with a "return" button. I have a general idea of how to do this, but I don't know how to put it together. I think I need an IBAction method for each button, and in each method a navigation controller with pushViewController. So far, i've tried the following code, but even if it compiles properly and runs when i push the button, there is no change of screen... -(IBAction) toNext(id)sender{ NSLog(@"before code"); NextViewController *nvc = [[NextViewController alloc] initWithNibName:@"NextView" bundle:nil]; [self.navigationController pushViewController:nvc animated:YES]; [nvc release]; NSLog(@"after code"); } If someone had a nice tuto for me, it could be of some help... thx

• How do I override methods of nested types?

  - by Mason Wheeler

  I've got a custom TObjectList descendant in Delphi 2009, and I'd like to play with its enumerator a bit and add some filtering functionality to the MoveNext method, to cause it to skip certain objects. MoveNext is called by DoMoveNext, which is a virtual method, so this shouldn't be difficult to override... except for one thing. The TEnumerator for TObjectList isn't its own class; it's declared as a nested type within the TObjectList declaration. Is there any simple way to override TEnumerator.DoMoveNext in my descendant class, or do I have to reimplement the whole TEnumerator? It's not a very big class, but I'd prefer to keep redundancies to a minimum if I can...

• Definitive list of protocols supported by the WebClient and WebRequest classes.

  - by the-locster

  The docs state: From WebRequest.Create Method The .NET Framework includes support for the http://, https://, and file:// URI schemes. Custom WebRequest descendants to handle other requests are registered with the RegisterPrefix method. However I've also been using this class to get files via ftp (not listed in the docs). Is there a definitive list of supported protocols documented anywhere? UPDATE: To clarify. Yes additional protocols can be plugged-in, but what is the standard/baseline set of protocols supported in the class framework assuming I haven't registered any others. e.g. sftp, tftp?

• Android: setting up a google map class. bit of advice required.

  - by Capsud

  Hey there, Ok so this is what i've got. Button anandabutton = (Button) findViewById(R.id.anandaAddressButton); anandabutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); startActivityForResult(myIntent,0); } }); This method opens up my MapClass class which at the moment I just have set to show the location of one place. But I have a load of buttons and rather than making a lot of different mapClass classes for each button, I am wondering can I just use the one class and depending on what button 'id' is pressed, it will check an 'if statement' and then put in the correct coordinates into the method to display the map. It would be a lot neater than coding up like 20-30 classes. I'm not sure if i've explained that right so if not let me know. Thanks for any help.

• Wrapper class that creates objects at runtime and stores data in an array.

  - by scriptingalias

  I tried making a wrapper class that encapsulates an object, a string (for naming and differentiating the object instance), and an array to store data. The problem I'm having now is accessing this class using methods that determine the "name" of the object and also reading the array containing some random variables. import java.util.Arrays; import java.util.Random; public class WrapperClass { String varName; Object varData; int[] array = new int[10]; public WrapperClass(String name, Object data, int[] ARRAY) { varName = name; varData = data; array = ARRAY; } public static void getvalues() { } public static void main(String[] args) { int[] array = new int[10]; Random random = new Random(3134234); for(int i = 0; i < 10; i++) { for (int c = 0; c < 10; c++) { array[c] = random.nextInt();//randomly creates data } WrapperClass w = new WrapperClass("c" + i, new Object(),array); } } }

• two HashMap iteration

  - by user431276

  I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !

• How to create view in RoR if skipped during controller generation

  - by swapnesh

  When I run this: rails generate controller hello index it no doubt generates hello controller, but accidentally when I run another command like this: rails generate controller world it creates the world controller successfully, but missed the Route "world/index" like as "hello/index". For this mistake I need to use destroy controller and then generate it once more, is thr some kind of mid way command that I can generate if forgotten something rather than destroying and creating every time. This command rails generate controller contact-us index creates a route as contact_us/index or contact_us after changing routes.rb under config folder. How could I create a more SEO friendly URL in RoR? Like localhost:3000/contact-us? I am working on some very basic rules to follow RoR..like 3 static pages (Home, About us, Contact Us) Just simple html content to understand more, will certainly add more features to it as well. localhost:3000/home localhost:3000/About_us localhost:3000/contact_us I created this via creating home, About_us, contact_us controller command and then changed html in views. Since I am on an initial phase, I read somewhere for static pages we can create this in our public like what we have error pages there in the folder or the approach im using is correct?

• Looking for a way to get HTTP Digest Authentication headers from incoming http requests

  - by duncancarroll

  I've been working on a REST implementation with my existing Cake install, and it's looking great except that I want to use HTTP Digest Authentication for all requests (Basic Auth won't cut it). So great, I'll generate a header in the client app (which is not cake) and send it to my cake install. Only problem is, I can't find a method for extracting that Digest from the request... I've looked through the Cake API for something that I can use to get the Digest Header. You'd think that Request Handler would be able to grab it, but I can't find anything resembling that. There must be another method of getting the digest that I am overlooking? In the meantime I'm writing my own regex to parse it out of the Request... once I'm done I'll post it here so no one has to waste as much time as I did hunting for it.

Up to this stage I know it works fine over the LAN, here's where the exception occurs over the WAN and is the first place a method in the server is called: private class PingLabel extends JLabel { private static final long serialVersionUID = 1L; public PingLabel() { super(""); runPing(); } public void setText(String text) { super.setText("Ping: " + text + "ms"); } public void runPing() { try { PingThread pt = new PingThread(); gameServer.ping(); pt.setRecieved(true); setText("" + pt.getTime()); } catch (RemoteException e) { e.printStackTrace(); } } } That's a label placed on the launcher as a ping test. the method ping(), in gameserver does nothing, as in is a null method. It's worth noting also that ports 1099 and 7099 are forwarded to the server machine (which should be obvious from the stack trace). Can anyone see anyting I'm missing/doing wrong? If you need any more information just ask. EDIT: I'm practically certain the problem has nothing to do with my router settings. When disabling my port forwarding settings I get a slightly different error: Client exception: java.rmi.ConnectException: Connection refused to host: (-WAN IP NOT LOCAL IP-); but it appears both on the machine locally connected to the server and on the remote machine. In addition, I got it to work seamlessly when connecting the server straight tho the modem (cutting out the router. I can only conclude the problem is in my router's settings but can't see where (I've checked and double checked the port forwarding page). That's the only answer i can come up with.
