  • 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?

  • How to facebook getuser() after login with javascript SDK

    - by user1848205
    So I have to ask for extended permission by clicking the enter button, but after the login is necessary to refresh the page in order to display the app. Here's my code: <?php require 'facebook.php'; $facebook = new Facebook(array( 'appId' => '< THE APPID >', 'secret' => '< THE SECRET >', 'cookie' => true, )); $user = $facebook->getUser(); if ($user) { try { $user_profile = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); $user = null; } } ?> <body> <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : '< THE APPID >', status : true, cookie : true, xfbml : true }); // Additional initialization code such as adding Event Listeners goes here $('#btn-enter').click(function(){ login(); }); }; (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); function login() { FB.login(function(response) { if (response.authResponse) { // connected } else { // cancelled } //}); }, {scope: 'read_friendlists,friends_photos,publish_stream'}); } </script> <?php if ($user): ?> <!--Here is my APP--> <?php else: ?> <a id="btn-enter">Enter</a> <?php endif ?> Is there a better way to do this ? What works for me is: function login() { FB.login(function(response) { if (response.authResponse) { top.location.href='https://the_app_url'; } else { } //}); }, {scope: 'read_friendlists,friends_photos,publish_stream'}); } But this causes the entire page to refresh and is not 'elegant' per se...

  • Manage bad_alloc exception in C++ construtor

    - by Jimmy zhang
    I have Java experience and recently am doing some C++ coding. My question is that if I have class A, in which I have to instantiate class B and class C as two of the member variables of A. If in the constructor of A, should I assume that allocations of class B and C never fail, and handle the bad allocation exception in the destructor of A? If I don't make that assumption, meaning that I add some try catch block to catch bad_alloc of class B and class C, then if the allocation exception occurs, should I do clean up in the constructor of A? What are the recommended practices? If "new" generates a bad allocation, what value does the pointer carry?

  • Is there a way to determine gaps in try/catch coverage?

    - by Mike Pateras
    I'm debugging a service that's experiencing some problems on start-up. To aid me in this, I'm wrapping pretty much everything in a try/catch block, and writing any errors to a file. I don't want to put them in every method, I just want to put them in the highest level methods so that they catch exceptions from other methods. Something is getting through, though, as the service does stop under some conditions. Is there a way to determine where the gaps in my try/catch coverage are, other than by sight?

  • 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!

  • 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?

  • UIView animations on a path not linear

    - by chis54
    I have an iOS application that I want to animate a falling leaf (or several). I have my leaf image in an ImageView and I've figured out a simple animation from the documentation: [UIView animateWithDuration:4.0f delay:0 options:UIViewAnimationTransitionFlipFromLeft animations:^(void) { leaf1ImageView.frame = CGRectMake(320, 480, leaf1ImageView.frame.size.width,leaf1ImageView.frame.size.height); } completion:NULL]; This will make the leaf go from its starting position to the bottom right corner in a straight line. How would I animate this to follow a path or curve like a parabola or sinusoid and maybe even rotate the image or view? Would this be done in the animations block? Thanks in advance!

  • 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 to kill a thread immediately from another thread in java?

    - by Sara
    Hi, is there anyway to kill a thread or interrupt it immediately. Like in one of my thread, i call a method which takes time to execute (2-4 seconds). This method is in a while(boolean flag) block, so i can interrupt it from the main thread. But the problem is, if i interrupt it; it will wait till the executing loop is finished and then on next conditional check, it will stop execution. I want it to stop right then. Is there anyway to do this?

  • 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?

  • Question regrarding declaring a property

    - by Simon
    Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is, What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code, Interface: @interface myClass : NSObject { NSString *myClass_name; // LINE 1 } @property(nonatomic, retain) NSString *myClass_name; // LINE 2 @end Implementation: @implementation myClass @synthesize myClass_name @end Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?

  • How to use #ifdef entities as part of functions in header files

    - by Crazyjavahacking
    I would like to ask if it is possible to use the entities defined in #ifdef block in header files. To be clear, I have following code: #ifdef #include <winsock2.h> #define SOCKET_HANDLE SOCKET #define CONNECTION_HANDLE SOCKET #endif SOCKET_HANDLE createServerSocket(const char* hostAddress, short port); I am Java developer and this seems completely fine for me. However compiler has a problem with this. Can you explain why is that code a problem? Also how can I force to compile it. (The idea is to have generic interface and conditional compilation to determine real types according to running platform at compile time.) Thanks

  • How-to handle errors in Vim Script ?

    - by ereOn
    In my .vimrc file, I have the following function, which folds the licensing information on the top of some .hpp and .cpp files: " Skip license function! FoldLicense() if !exists("b:foldedLicense") let b:foldedLicense = 1 1;/\*\//fold endif endfunction au BufRead *.hpp call FoldLicense() au BufRead *.cpp call FoldLicense() This works well, but if I open a .cpp file which doesn't have any licensing information block, Vim complains that the pattern is not found. Fair enough, but is there a way so that he stops complaining and just does nothing if the pattern is not found ? Thanks !

  • Remove Attributes onmouseover and onmouseout

    - by Abs
    Hello all, I am trying to make use of JQuery's remove attribute like this: $('#rom-img_1').removeAttr('mouseover'); $('#rom-img_2').removeAttr('mouseout'); However, it does not remove the effects of the events as the events are still triggered on mouseover and on mouseout. I have tried adding "on" before the events names too but JQuery doesn't use it like that. Why isn't this working and how can I remove those attributes. This is a bit of the HTML: <div onmouseout="$('#heart_401').css({'display':'none'});" onmouseover="$('#heart_401').css({'display':'block'});" id="row-img_11"></div> Thanks all for any help

  • 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>

  • PL/SQL embedded insert into table that may not exist

    - by Richard
    Hi, I much prefer using this 'embedded' style inserts in a pl/sql block (opposed to the execute immediate style dynamic sql - where you have to delimit quotes etc). -- a contrived example PROCEDURE CreateReport( customer IN VARCHAR2, reportdate IN DATE ) BEGIN -- drop table, create table with explicit column list CreateReportTableForCustomer; INSERT INTO TEMP_TABLE VALUES ( customer, reportdate ); END; / The problem here is that oracle checks if 'temp_table' exists and that it has the correct number of colunms and throws a compile error if it doesn't exist. So I was wondering if theres any way round that?! Essentially I want to use a placeholder for the table name to trick oracle into not checking if the table exists.

  • Forking Multiple Apps Under Python Subprocess

    - by noxtion
    Hello all. I have been looking through Google and SO for something that could help me solve this but I have run into a block. I am a bit new to Python but I am looking for a way to run multiple apps that will continuously run in the background. For example, I need 4 apps to start up with a param -appnum set to a different value. I would like to use python to count up and then start up a new app that will continue to run. I assumed I would use subprocess but I feel a bit overwhelmed by the documentation. I also plan to have the app print out sequences of numbers and would like to redirect this to a file. I noticed some of the SO questions talked about this, but I am a little confused on what to do. -Mike

  • Can a function defined in a bookmarklet be called from a page-level script?

    - by Soviut
    I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

  • Three boolean values saved in one tinyint

    - by Casper
    Hello, probably a simple question but I seem to be suffering from programmer's block. :) I have three boolean values: A, B, and C. I would like to save the state combination as an unsigned tinyint (max 255) into a database and be able to derive the states from the saved integer. Even though there are only a limited number of combinations, I would like to avoid hard-coding each state combination to a specific value (something like if A=true and B=true has the value 1). I tried to assign values to the variables so (A=1, B=2, C=3) and then adding, but I can't differentiate between A and B being true from i.e. only C being true. I am stumped but pretty sure that it is possible. Thanks

    I'm trying to center an image in php. I'm currently using this line of code echo '<img src="newimage.jpg" width="110" height="120" class="centre">'; However, this seems to have no effect. I've also tried using something like this, img.center { display: block; margin-left: auto; margin-right: auto; } <img src="newimage.jpg" alt="Suni" class="center" /> but this merely gives me a syntax error, how do I go about fixing this? Thanks
