  • Android string formatiing from xml

    - by mann
    I am parsing xml from server. One of its node contains data like <distance>16.3432434324354324km</distance> I am putting it into hashmap like for (int i = 0; i < nl.getLength(); i++) { map.put(KEY_DISTANCE, parser.getValue(e, KEY_DISTANCE)); // adding HashList to ArrayList menuItems.add(map); } Everything is nice. But i want it two decimal places for example i want its value should be 16.34km rather then 16.343234324342342km I tried with DecimalFormat twoDForm=new DecimalFormat("##.00"); try{ Double StartVTwo=Double.valueOf(KEY_DISTANCE); Double resultDouble1 = Double.valueOf(twoDForm.format(StartVTwo)); Log.e("check", String.valueOf(resultDouble1)); }catch (NumberFormatException e){ Log.e("error"," This is error "); } But it shows exception and prints this message. Any help would be appreciated!!

  • Help with getParent() downcast.

    - by Preformed Cone
    I'm learning android/java and have this example code I can't get to work: OnRatingBarChangeListener l = new OnRatingBarChangeListener() { public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromTouch) { Integer myPos=(Integer)ratingBar.getTag(); RowModel model=getModel(myPos); model.rating = rating; LinearLayout p=(LinearLayout)ratingBar.getParent(); TextView l=(TextView)p.findViewById(R.id.label); l.setText(model.toString()); } }; Everything works except the LinearLayout / getParent() downcast. At runtime it creates a ClassCastException. If I comment out that block of code then everthing works fine. What am I missing?

  • Prepared statement initialized tiwice and closed once

    - by sonam
    Hi, I want to know that if a PreparedStatement object is initialized twice the way shown in code snippet below and closed only once in finally block, will it fail to close? I am not getting any error in this code but will it be a better idea to use 2 different preparedStatements instead of one. I think it fails to close the preparedStatement at #1. Connection conn = null; PreparedStatement ps = null; try { conn = getConnection(); ps = conn.prepareStatement(QueryUtil.UPDATE_POLICY_DETAILS); // #1 ps.setInt(1, iCancellationPolicyId); ps.executeUpdate(); //some code here ps = conn.prepareStatement(QueryUtil.UPDATE_POLICY_CHARGES); // #2 ps.setInt(1, iCancellationPolicyId); ps.executeUpdate(); //some code here } catch (SQLException sqlExp) { sqlExp.printStackTrace(); LOG.fatal(sqlExp); } finally { conn.close(); ps.close(); }

  • How do detect that transaction has already been started?

    - by xelurg
    I am using Zend_Db to insert some data inside a transaction. My function starts a transaction and then calls another method that also attempts to start a transaction and of course fails(I am using MySQL5). So, the question is - how do I detect that transaction has already been started? Here is a sample bit of code: try { Zend_Registry::get('database')->beginTransaction(); $totals = self::calculateTotals($Cart); $PaymentInstrument = new PaymentInstrument; $PaymentInstrument->create(); $PaymentInstrument->validate(); $PaymentInstrument->save(); Zend_Registry::get('database')->commit(); return true; } catch(Zend_Exception $e) { Bootstrap::$Log->err($e->getMessage()); Zend_Registry::get('database')->rollBack(); return false; } Inside PaymentInstrument::create there is another beginTransaction statement that produces the exception that says that transaction has already been started.

  • How can I switch off exception handling in MSVC?

    - by Tamara
    Does anybody know how to switch off exception handling option in MSVC? I tried to set the option 'Enable C++ exceptions' to 'NO' and I got warning: warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc I would like to switch off the exception handler, too, but I don't know how. In my application I basically need more speer than stability, therefore I chose switching off the exception handling. I do not have any try/catch blocks, but I do use STL. When I switch the option 'Enable C++ exceptions' to 'NO' is there any way how to get rid of those warnings?

  • Recieveing "EXC_BAD_ACCESS" before any UI elements load (on device only)

    - by morgancodes
    Everything works fine on the simulator, but I gete EXC_BAD_ACCESS when I try to load my app on the device. I've put in a bunch of NSLogs to try and catch where it happens, but the log statements are never reached. Also, the UI doesn't load. So, seems the problem is happening before any of my code is reached. I tried a clean build, no luck. Also tried building and installing a different app, which works fine. So, looks like there's something wrong with my app, but it's something that happens before any of my code gets called. So, any ideas?

  • Can Spring access-denied-handler refer to popup?

    - by Rens Groenveld
    I am working with Spring Security 3.1.x and have implemented method annotation securities. As I want, when I perform a certain action while being logged in as a used that doesn't have the rights, I get a 403 acces is denied in my console! Perfect! Now I would like to catch this 403, and give the user a popup with a custom message. I don't want to redirect users to a page saying that they have no rights. Is there any way the access-denied-handler of Spring can take care of a popup? Or can it only redirect to another page? Maybe there are other options for me? Thanks in advance!

  • Vista Basic theme ribbon issue

    - by Alain Rist
    Under Vista, when in Basic theme, after calling IUIFramework::Destroy() the Vista theme is lost, and enlarging the window does not display outside of the initial area. You can repro it easily with the SimpleRibbon SDK sample. In simpleribbon.cpp, insert in the WndProc switch block: case WM_KEYUP: DestroyFramework(); InvalidateRect(hWnd, NULL, TRUE); break; Compile, run, hit a key and try to enlarge in Vista Basic Theme (no problem in Win7 or Vista aero or Windows classic). How to work around? cheers, AR

  • Postgresql error: could not open segment 1 of relation base/20983/2416

    - by kokonut
    I'm running a Postgresql query and getting the following error: ActiveRecord::StatementInvalid (PGError: ERROR: could not open segment 1 of relation base/20983/24161 (target block 5046584): No such file or directory The query is of the format 'SELECT "locations".* FROM "locations" WHERE ("locations"."id" IN (115990, 78330, 77891, 78248, ...)' with about 600 ids in the IN clause - not an optimal query I know but it's what I have to work with for the moment! The server is running PostgreSQL 8.4.6 on x86_64-pc-linux-gnu, compiled by GCC gcc-4.4.real (Ubuntu 4.4.1-4ubuntu9) 4.4.1, 64-bit. Postgis 1.5 is also installed, and the locations table contains a geometry column. Anyone have any idea what could be causing the error? Thanks!

  • EditText and Button on the same line with Textiew underneath?

    - by Kevin
    Hi, I am trying to have an EditText widget next to a button with a text view underneath. The EditText should resize and fill the screen accordingly, while the button's width is always only what it needs to be by setting the width to wrap_content. The layout should not be relative. Below is the code I have so far some of which was found here on StackOverflow. Removing the text view gives the desired appearance for the EditText and button, but when the TextView is added the view goes to ... well. Not sure why the code is not showing? I put it into a < code< pre block without success. http://pastebin.com/WgH6qrTm

  • How do I assign a value from params, or session, whichever exists?

    - by irkenInvader
    What is the "Rails-way" or the "Ruby-way" of doing the following: In my controller, I'm creating and instance of an Options class. It will be initialized with information in the params hash if the params hash exists. Otherwise, it will check the sessions hash for the information. Finally, it will initialize with defaults if neither params nor session has the data it needs. Here is how I'm doing it now (it works fine, but it seems a little ugly): if params[:cust_options] @options = CustomOptions.new( params[:cust_options] ) else if session[:cust_options @options = CustomOptions.new( session[:cust_options] ) else @options = CustomOptions.new end end session[:cust_options] = @options.to_hash Like I said, everything is working fine, I'm just looking for a more idiomatically Ruby way of writing this block of code.

  • Jquery/CSS help needed to make fallback for IE and older browsers

    - by matt_50
    Wondering if any of you can help me: I've made a signup modal that uses a CSS transform to switch between two methods of signing up. I've decided to try a 'card flip' type effect. Have a look at this JSfiddle in any browser that supports CSS 3D transforms - click the 'old fashioned way' text to 'flip' the modal (simplified for demo purposes): http://jsfiddle.net/voodoo6/cnTMz/8/ Then take a look in IE8/9 - as the 'back' is taller than the front and IE does;t support 'backface-visibility: hidden;' the reverse can be seen below the front. I've been trying to use JQuery and conditional CSS to 'display:none' the 'back' on load in IE (and older browsers), then add a 'display:block;' class to show it on click, problem is, I'm a JQuery beginner and have been struggling to get it to work! Not even sure if this is the best approach? Can anybody suggest an approach that would get this working in less-capable browsers? Thanks for any advice..

  • What difference does it make to use several script blocks on a web page?

    - by Jan Aagaard
    What difference does it make to use more than one script block on a web page? I have pasted in the standard code for including Google Analytics as an example, and I have seen the same pattern used in other places. Why is this code separated into two separate script blocks instead of just using a single one? <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try{ var pageTracker = _gat._getTracker("UA-xxxxxx-x"); pageTracker._trackPageview(); } catch(err) {} </script>

  • write cache and write sequence order

    - by excanoe
    ok, here i have some weird question: let say we have some binary file (.log), and sequence of write operations, for example log1, log2, log3 and each has some block size n (raw data). question: can I be sure that log1,log2 and log3 sequences can be written in the correct order in ONE file, even if i have few cache levels (disk hardware and os level)? update very interested in what will be with records order (not with records) if we have software or hardware failure (reboot or another reason). update there can be some percent of write failures, but main question is: will write order stay correct?

  • Is there a faster way to download a page from the net to a string?

    - by cphil5
    I have tried other methods to download info from a URL, but needed a faster one. I need to download and parse about 250 separate pages, and would like the app to not appear ridiculously slow. This is the code I am currently using to retrieve a single page, any insight would be great. try { URL myURL = new URL("http://www.google.com"); URLConnection ucon = myURL.openConnection(); InputStream inputStream = ucon.getInputStream(); BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream); ByteArrayBuffer byteArrayBuffer = new ByteArrayBuffer(50); int current = 0; while ((current = bufferedInputStream.read()) != -1) { byteArrayBuffer.append((byte) current); } tempString = new String(byteArrayBuffer.toByteArray()); } catch (Exception e) { Log.i("Error",e.toString()); }

  • Is the "message" of an exception culturally independent?

    - by Ray Hayes
    In an application I'm developing, I have the need to handle a socket-timeout differently from a general socket exception. The problem is that many different issues result in a SocketException and I need to know what the cause was. There is no inner exception reported, so the only information I have to work with is the message: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond" This question has a general and specific part: is it acceptable to write conditional logic based upon the textual representation of an exception? Is there a way to avoid needing exception handling? Example code below... try { IPEndPoint endPoint = null; client.Client.ReceiveTimeout = 1000; bytes = client.Receive(ref endPoint); } catch( SocketException se ) { if ( se.Message.Contains("did not properly respond after a period of time") ) { // Handle timeout differently.. } }

  • Handling download abort in PHP

    - by Aron Rotteveel
    Is it somehow possible to handle a download abort in PHP? In this specific case I am not speaking of a connection abort, but handling the event that triggers when the 'cancel' button in the browser download dialog button is clicked. Since this dialog already interprets the headers of the file that is to be download but does not actually start the download, it only seems logical there should be some way to catch this. Small (pseudo) code example to clear things up: // set some headers header('...'); // Question: what happens between the part where the headers are sent // and the actual data is being outputted to the client? IE: this is the part // where the download dialog should show up // Logical question that follows is: is there a way to detect a 'cancel'? $filename = '/some/file.txt'; $handle = fopen($filename, 'rb'); // output data to client while (!feof($handle)) { echo fread($handle, 8096); } fclose($handle);

  • Escaping if/else in Jade template

    - by Collin Estes
    So I have a simply block of html in my jade template with a loop: each dude, i in dudes div(class='someClass') div.otherStuff span.someContent #{name} I want to apply a data attribute to my top most div when a certain looping condition is met, in this case the first dude, I set it up like this each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') else div(class='someClass') div.otherstuff span.someContent Setup like this it causes the div.otherStuff div and the span.someContent to only display on the else condition. I've moved the tab spaces around on those items but I can't get it escape that else and give the div.otherStuff and span.someContent to both the first dude and the subsequent dudes after that. I've also tried setting that data attr to a variable and trying to apply it that way but without any success. What I end up doing to get around it is this: each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') div.otherstuff span.someContent else div(class='someClass') div.otherstuff span.someContent How do I escape that if/else so I dont have to duplicate the div.otherStuff and span.someContent?

  • how to display "complex" widgets in a list in pyqt?

    - by Giorgio Gelardi
    I'm quite new to QT and I have to display a list of "panels" like this: My datamodel handles different classes' instances, so having more than one panel layout would be great - but it's not a requirement. Btw I have to catch mouse clicks on the images to execute related actions. I'm thinking about use some html capable widget (QWebPage?) to render the items in a QListView or QListWidget, but as I said, I don't know QTs so much and need a direction (delegates? stylesheets?). Any help will be appreciated.
