  • Casting Class into String and Vice Versa in JAVA

    - by topgun_ivard
    I have a program in which I need to store a Class object into memory by casting it into String. Is it possible to convert the String back into the original Class so that I can use that class variables? I am doing this in JAVA. Example: test.java class hello{ public String h1; public String h2; } public class test { public static void main(String[] args) { hello h = new hello(); h.h1 = "hello"; h.h2 = "world"; String s = h.toString(); System.out.println("Print s : "+s); // Now I need to convert String s into type hello so that // I can do this: // (hello)s.h1; // (hello)s.h2; } } NOTE: this is not a homework, this is a personal project and I would be grateful if anyone can help! Thanks! Ivar

  • Using UIImageViews for 'pages' in an iPhone/iPad storybook app?

    - by outtoplayinc
    I'm new to iPhone programming, and well, what seems obvious to me may seem silly to a seasoned coder. I did a few 'switching views' tutorials on Youtube, and basically, they seems to work nicely for adding pages to a storybook type app. You add a UIViewController and associated view for each page. My question is would this become insanely slow, or a memory hog if I continued this method for say....35+ pages? Each page would also have a sound file associated with it that would play narration when a page load and stops when we leave. Basically, think of a powerpoint type app, with sound, possibly animated image elements, next & back buttons. I'm probably thinking of this very simplistically, but that's where my experience is at for the moment. Any insight or tips as to better and or more efficient ways to proceed would be greatly appreciated.

  • Resources for Win32 C/C++ programming

    - by EricM
    I have experience in a variety of languages (Java, Perl, C#, PHP, javascript, ansi-C for microprocessors, Objective-C and others), with Win32 programming not being an area I've done a lot of work in. Now part of my job entails maintaining a large Win32 codebase that stretches back 15 years and includes everything from C written originally for Win95 to MFC to COM to 64-bit code for Win7 to C++ using Boost and so on. If there's a variation on how to do something it's in there. Are there any good Win32 C/C++ references that discuss both the proper way to do things today and give you a little sense of how things evolved? Something like this discussion of all the various boolean types, or how to approach the API monstrosity of simply copying a string. I don't see my career heading too far down this path, but I do like to understand what I'm working with and I think this is an important part of programming history. thanks, Eric

  • Sending a message from Objective-C and getting the return value?

    - by Nick Brooks
    I have this code NSString *tr = [self sendUrl:@"http://google.com/"]; But for some reason 'tr' will remain nil after it is executed. What am I doing wrong? sendUrl : - (NSString *)sendUrl:(NSString *) uri { NSLog(@"Requesting URI 1 ..."); // Prepare URL request to download statuses from Twitter NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:uri]]; NSLog(@"Requesting URI 2 ..."); // Perform request and get JSON back as a NSData object NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSLog(@"Requesting URI 3 ..."); // Get JSON as a NSString from NSData response NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; NSLog(@"Requesting URI 4 ..."); return json_string; }

  • WebView not responding when called from a method

    - by AragornSG
    I have an app with tabbar and webview. I'm trying to make the app come back to default url each time user taps the bar. Right now I'm intercepting taps and launching a method, however it's not affecting my webview. The same syntax for calling webview from awakeFromNib works, so I don't have a clue what's up. I suspect it's something to do with how I call the method, but I don't know what. Here is the code: #import "SecondViewController.h" @implementation SecondViewController - (void)awakeFromNib { NSString *loadURL = [NSString stringWithFormat:@"http://pageurl"]; // [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:loadURL]]]; SecondViewController *ptr = [[SecondViewController alloc] init]; [ptr goToPage]; } - (void) goToPage { NSLog(@"go to page"); NSString *newURL = [NSString stringWithFormat:@"http://pageurl"]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } Thanks fot your help!

  • Java Authenticator on a per connection basis?

    - by Martijn Laarman
    I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

  • Ruby On Rails Routes

    - by Kezzer
    I can't figure out how to get the following routes. Here's an extract from my routes.rb file: map.resources :treatments map.root :controller => "home" map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format' map.connect ':action', :controller => 'home' # replaces the need to manually map pure actions to a default controller map.resources :bookings map.resource :dashboard map.resource :home Now I do realise that the ordering matters, but I can't seem to get them to work correctly. What I want is so http://localhost:3000/bookings/new actually takes you to an action http://localhost:3000/bookings/signmeup if you're either not signed in, or haven't got a login. The problem is that if I change my routes around, when I attempt to create a new booking after I have logged in, then it doesn't POST the form submission and just takes me back to the view page. This is definitely because of the routes as if I rearrange map.resources :bookings to be before all of them, then it works. Any ideas?

  • ASP.NET: How to "reset" validation after calling Page_ClientValidate

    - by Josh Young
    I have an ASP.NET page with a jQuery dialog that is displayed to change some data. I am setting up the jQuery dialog so that when the user clicks the OK button it calls ASP.NET's Page_ClientValidate('validationGroup') via javascript, finds all the invalid controls and changes their CSS class. So here's the scenario: the user opens the dialog, keys in some invalid data, clicks OK (receiving the validation messages), and then clicks Cancel. Now the dialog is closed, but the validation messages are still there, so that when they open the dialog again, the data goes back to the way it was initially, but the form is still in the invalid state (the validation messages are still displaying). What I need is a "reset" function of sorts to call after calling Page_ClientValidate('validationGroup'). Does this exist?

  • How to refresh database data only in SQL Server

    - by MaxGeek
    So I want to copy just the data from a Prod database (SQL 2005) down to my local machine (SQL 2005 & SQL 2008 Management Studio installed). The problem is I'm running into foreign key constraints that are causing the task/scripts to fail. I can get by these errors if I import certain tables first, but is there an easier way to do this all at once? I'm not a DBA so I don't have access to the database back up. I've tried the SQL Import/Export data Wizard and Publishing Wizard, but it also gets the PK error.

  • C# app that uses Excel Interop, easy switch between 2003 2007?

    - by user320781
    I have an app written that just does really basic I/O on a spreadsheet. Read in a bunch of cells, do some sorting, and dump the output back into another spreadsheet. Works great on my machine. I have Office 2003 installed. When it runs on someone elses machine with 2007, it bombs, presumably due to the different versions of the Interop assemblies. I was hoping someone knew a way to dynamically change which/where the assembly is loaded from depending on the office version (getting the office version is easy from the registry). Sifting thru the rest of the internet, i didnt see anything to indicate that was possible :( . I tried installing the 2007 PIAs, but when i try to add a reference, they dont show up and i have no idea where to browse for them (they arent in the c:\windows\assemblies\; maybe the install didnt work). Am I going to have to get a machine with 2007 installed to build on every time i need to make updates?

  • Ruby Methods: return an usage string when insufficient arguments are given

    - by Shyam
    Hi, After creating a serious bunch of classes, with initialize methods, loading them in IRb requires to look back at the code. However, I think it should be easy enough to return a usage message, instead of: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

  • How would you use version control for personal data, like a personal website?

    - by nn
    This is more a use-case question, but I generate static files for a personal website using txt2tags. I was thinking of maybe storing this information in a git repository. Normally I use RCS since it's simplest, and I'm only a single user. But there just seems to be a large trend of people using git/svn/cvs/etc. for personal data, and I thought this may also be a good way to at least learn some of the basics of the tool. Obviously most of the learning is done in an environment where you collaborate. So back to the question: how would you use use a version control system such as git, to manage a personal website?

  • Classic asp paging and session state

    - by flavour404
    Hi, Working on a classic asp page that uses paging. The error I am having a problem with is this: Lets say that you have 5 pages returned in your record set and you are on page 2. You leave and come back, you then press the link for page 3, the trouble is your session has timed out. I don't know why this happens but the page is reloaded, but the session check is bypassed and of course when the page attempts to retrieve the record set the session variables are now empty so I am getting a message stating: error near ',' line 1, because now the query is defunct. How do I get around this? Thanks, Ron.

  • Is it possible to remove all event handlers of a given element in javascript?

    - by MartyIX
    Hi, I would like to remove ALL handlers for a given event type. Let's say I've added twice "onclick event" to a button and now I would like to return back to the original state where no event handler was set to the button. How can I do that? P.S.: I've found removeEventListener (non-IE)/detachEvent (IE) methods but the functions want me to pass as a parameter the function that handles the event which seems to me quite clumsy because I would have to store the functions somewhere. EDIT: http://ejohn.org/blog/flexible-javascript-events/ - I'm now using this code Thank you!

  • Sum of distinc rows after a 1-many table join

    - by Lock
    I have 2 tables that I am joining. Table 1 has 1-many relationship with table 2. That is, table 2 can return multiple rows for a single row of table 1. Because of this, the records of table 1 is duplicated for as many rows as are on table 2.. which is expected. Now, I have a sum on one of the columns from table 1, but because of the multiple rows that get returned on the join, the sum is obviously multiplying. Is there a way to get this number back to its original number? I tried dividing by the count of rows from table 2 but this didnt quite give me the expected result. Are there any analytical functions that could do this? I almost want something like "if this row has not yet been counted in the sum, add it to the sum"

  • How might you unobtrusively enhance the jQuery Datepicker class?

    - by Teflon Ted
    You can pass special strings into jQuery's Datepicker class setDate() method like "+7" which will be translated into "7 days from today": http://docs.jquery.com/UI/Datepicker#method-setDate But you can't get that "+7" back out. When you call getDate() you get the calculated resulting date. I have a use case where I need to pull out the special string "+7" for propagation. One chunk of code is passing a special string into the Datepicker and passing the Datepicker over to another chunk of code which pulls out the date, but the latter sometimes needs to know the special string rather than the calculated date. So I need to enhance the Datepicker tool to (a) store the special code internally and (b) expose it via a method like getOriginallyPassedInDate() or some such. I'm not a jQuery/Javascript ninja so I could really use some guidance on how I might preferably-unobtrusively add the necessary functionality to the Datepicker class, the way you might monkey-patch an object in Ruby I'm guessing.

  • Git workflow idea to push an unfinished local branch to remote for backup purposes

    - by Zubin
    Say I'm currently working on a new feature which I've branched off of the 'dev' branch and I've been working for several days and it's not yet ready to be merged with 'dev' and pushed. Although I have made several commits and have been pulling changes to dev and then merging dev into my feature branch to keep myself updated. Here's my question. Is it a good idea to push my feature branch to a new branch (with the same name as my local branch) onto origin (say GitHub) just for back-up purposes and later on when it's merged into 'dev' and/or 'master' delete it from origin.

  • Retrieving Large Lists of Objects Using Java EE

    - by hallidave
    Is there a generally-accepted way to return a large list of objects using Java EE? For example, if you had a database ResultSet that had millions of objects how would you return those objects to a (remote) client application? Another example -- that is closer to what I'm actually doing -- would be to aggregate data from hundreds of sources, normalize it, and incrementally transfer it to a client system as a single "list". Since all the data cannot fit in memory, I was thinking that a combination of a stateful SessionBean and some sort of custom Iterator that called back to the server would do the trick. How have you successfully solved this problem in the past?

  • Windows Phone: Updating backend datastore (via web service) while keeping UI very responsive

    - by will
    I am developing a Windows Phone app where users can update a list. Each update, delete, add etc need to be stored in a database that sits behind a web service. As well as ensuring all the operations made on the phone end up in the cloud, I need to make sure the app is really responsive and the user doesn’t feel any lag time whatsoever. What’s the best design to use here? Each check box change, each text box edit fires a new thread to contact the web service? Locally store a list of things that need to be updated then send to the server in batch every so often (what about the back button)? Am I missing another even easier implementation? Thanks in advance,

  • Namespace with index action in Rails

    - by yuval
    I have an admin controller located inside /controllers/admin/admin_controller.rb I also have a pages controller located inside /controllers/admin/pages_controller.rb In my routes.rb file, I have the following: map.namespace :admin do |admin| admin.resources :pages end When the user goes to localhost:3000/admin, I'd like the user to see a page with a link to /admin/pages (Pages CRUD) and to / (To go back home). Since I am using a namespace, I cannot have an index action for /admin. How would I get this done and still have my controllers located inside my /controllers/admin folder (rather than using admin as a map.resources component and a has_many association to pages). Please note I am only interested in the show action of admin. Thank you!

  • Forwarding activity result to parent, with singleTop launch mode

    - by Joe
    I have two activities: a MainListActivity, and a DetailViewActivity. DetailViewActivity is set with android:launchMode="singleTop". When clicking an item in the "main list" activity, it launches the "detail view" activity via: startActivityForResult(detailIntent, REQUEST_CODE_DETAIL); If I then call setResult(RESULT_OK, resultData); and finish(); from within the Detail activity, that resultData is received by the "main list" activity's onActivityResult(..) method correctly. However, if I implement a "see previous"/"see next" type of navigation within the Detail activity, and implement it using singleTop, that result no longer gets sent back to the initial activity: Intent nextItemIntent = this.createIntent(nextId); nextItemIntent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT); startActivity(nextItemIntent); // at this point, my DetailActivity's onNewIntent() method is called, and the new data is loaded properly But from here, when I call setResult(..) and finish(), my MainList activity never receives the new/updated result. Anyone know what I'm doing wrong?

  • Flexible string handling in Visual Studio 2008 C++

    - by David
    I'm slowly starting to get the hang of the _T stuff in Visual Studio 2008 c++, but a few things still elude me. I can see the benefit of the flexibility, but if I can't get the basics soon, I think I'll go back to the standard way of doing this - much less confusing. The idea with the code below is that it scans the parameters for -d and then stores the text that follows that in the string variable fileDir. It also ignores any other parameters. Any help is appreciated. //Console application Parameters::Parameters(int argc, _TCHAR* argv[]) { _Tstring fileDir; // Is there some kind of _t variable to use here for a string? for (int i = 0; i < argc; i = i + 1) { if (_tccmp(argv[i], _T("-d")) == 0) // this appeared to accept anything starting with - { i = i + 1; fileDir = argv[i] } } _tprintf("Parameter value found: %s\n", fileDir); }
