  • How SQLite on Android handles long strings?

    - by Levara
    I'm wondering how Android's implementation of SQLite handles long Strings. Reading from online documentation on sqlite, it said that strings in sqlite are limited to 1 million characters. My strings are definitely smaller. I'm creating a simple RSS application, and after parsing a html document, and extracting text, I'm having problem saving it to a database. I have 2 tables in database, feeds and articles. RSS feeds are correctly saved and retrieved from feeds table, but when saving to the articles table, logcat is saying that it cannot save extracted text to it's column. I don't know if other columns are making problems too, no mention of them in logcat. I'm wondering, since text is from an article on web, are signs like (",',;) creating problems? Is Android automaticaly escaping them, or I have to do that. I'm using a technique for inserting similar to one in notepad tutorial: public long insertArticle(long feedid, String title, String link, String description, String h1,tring h2, String h3, String p, String image, long date) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_FEEDID, feedid); initialValues.put(KEY_TITLE, title); initialValues.put(KEY_LINK, link); initialValues.put(KEY_DESCRIPTION, description ); initialValues.put(KEY_H1, h1 ); initialValues.put(KEY_H2, h2); initialValues.put(KEY_H3, h3); initialValues.put(KEY_P, p); initialValues.put(KEY_IMAGE, image); initialValues.put(KEY_DATE, date); return mDb.insert(DATABASE_TABLE_ARTICLES,null, initialValues); } Column P is for extracted text, h1, h2 and h3 are for headers from a page. Logcat reports only column p to be the problem. The table is created with following statement: private static final String DATABASE_CREATE_ARTICLES = "create table articles( _id integer primary key autoincrement, feedid integer, title text, link text not null, description text," + "h1 text, h2 text, h3 text, p text, image text, date integer);";

  • MSSQL 2005 FOR XML

    - by Lima
    Hi, I am wanting to export data from a table to a specifically formated XML file. I am fairly new to XML files, so what I am after may be quite obvious but I just cant find what I am looking for on the net. The format of the XML results I need are: <data> <event start="May 28 2006 09:00:00 GMT" end="Jun 15 2006 09:00:00 GMT" isDuration="true" title="Writing Timeline documentation" image="http://simile.mit.edu/images/csail-logo.gif"> A few days to write some documentation </event> </data> My table structure is: name VARCHAR(50), description VARCHAR(255), startDate DATETIME, endDate DATETIME (I am not too interested in the XML fields image or isDuration at this point in time). I have tried: SELECT [name] ,[description] ,[startDate] ,[endTime] FROM [testing].[dbo].[time_timeline] FOR XML RAW('event'), ROOT('data'), type Which gives me: <data> <event name="Test1" description="Test 1 Description...." startDate="1900-01-01T00:00:00" endTime="1900-01-01T00:00:00" /> <event name="Test2" description="Test 2 Description...." startDate="1900-01-01T00:00:00" endTime="1900-01-01T00:00:00" /> </data> What I am missing, is the description needs to be outside of the event attributes, and there needs to be a tag. Is anyone able to point me in the correct direction, or point me to a tutorial or similar on how to accomplish this? Thanks, Matt

  • Authentication Problem in Silverlight - Cannot connect to SQL Server

    - by Johann
    Hi All, At the moment, when I try to register a user using the default Business Template in Silverlight, I am getting an error. Basically I am following a tutorial found on Channel 9 on how to build a business app with Silverlight. "An error has occurred while establishing a connection to the server. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 5) An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 1326)". I found a blog where it identifies the problem, and followed every step, however I am still getting the same problems. Here is my connection string:- <add name="SIEventManagerEntities" connectionString="metadata=res://*/EventManagerDBModel.csdl|res://*/EventManagerDBModel.ssdl|res://*/EventManagerDBModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=MONFU-PC;Initial Catalog=SIEventManager;Integrated Security=SSPI;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /> Any help would really be very much appreciated! Thanks

  • C++ Header file questions

    - by Karl
    So I'm trying to learn C++ and I've gotten as far as using header files. They really make no sense to me. I've tried many combinations of this but nothing so far has worked: Main.cpp: #include "test.h" int main() { testClass Player1; return 0; } test.h: #ifndef TEST_H_INCLUDED #define TEST_H_INCLUDED class testClass { private: int health; public: testClass(); ~testClass(); int getHealth(); void setHealth(int inH); }; #endif // TEST_H_INCLUDED test.cpp: #include "test.h" testClass::testClass() { health = 100; } testClass::~testClass() {} int testClass::getHealth() { return(health); } void testClass::setHealth(int inH) { health = inH; } What I'm trying to do is pretty simple, but the way the header files work just makes no sense to me at all. Code blocks returns the following on build: obj\Debug\main.o(.text+0x131)||In function main':| *voip*\test\main.cpp |6|undefined reference totestClass::testClass()'| obj\Debug\main.o(.text+0x13c):voip\test\main.cpp|7|undefined reference to `testClass::~testClass()'| ||=== Build finished: 2 errors, 0 warnings ===| I'd appreciate any help. Or if you have a decent tutorial for it, that would be fine too (most of the tutorials I've googled haven't helped)

  • How to reference var from frame on timeline in an object class

    - by brybam
    I'm using Flash Professional cs5/AS3 I'll try and describe this the best I can. I'm new to ActionScript. So, in my timeline I have a var on a frame that represents "lives" and i have some code in the timeline that takes down the number of lives depending on certain events, which all works great. so, now i wanted to make a constructor class that I could reuse for a bunch of movie clip objects and I only want these objects to be able to move if the lives variable is greater than certain number. So now, building my constructor class for these objects i just wanted put an if statement that is looking to see if the lives are greater than a certain number, which if it is then should make these objects do what i want...But, when i run the project I get "1120: Access of undefined property lives." lives is the var I made obviously like I said, and it works fine being referenced everyone else except when I make a new .as file for these objects then try and reference it. I get the same error when I try and establish "lives" in the main project class too. I'm not sure where I should put this var or how I can make it so i can reference it from an object class. I'm not really sure how to word or describe my issue which has made it hard to search for a tutorial. Any suggestions i'm sure this has to be a simple task.

  • How To Update EF 4 Entity In ASP.NET MVC 3?

    - by Jason Evans
    Hi there. I have 2 projects - a class library containing an EDM Entity Framework model and a seperate ASP.NET MVC project. I'm having problems with how your suppose to edit and save changes to an entity using MVC. In my controller I have: public class UserController : Controller { public ActionResult Edit(int id) { var rep = new UserRepository(); var user = rep.GetById(id); return View(user); } [HttpPost] public ActionResult Edit(User user) { var rep = new UserRepository(); rep.Update(user); return View(user); } } My UserRepository has an Update method like this: public void Update(User user) { using (var context = new PDS_FMPEntities()) { context.Users.Attach(testUser); context.ObjectStateManager.ChangeObjectState(testUser, EntityState.Modified); context.SaveChanges(); } } Now, when I click 'Save' on the edit user page, the parameter user only contains two values populated: Id, and FirstName. I take it that is due to the fact that I'm only displaying those two properties in the view. My question is this, if I'm updating the user's firstname, and then want to save it, what am I suppose to do about the other User properties which were not shown on the view, since they now contain 0 or NULL values in the user object? I've been reading a lot about using stub entities, but I'm getting nowhere fast, in that none of the examples I've seen actually work. i.e. I keep getting EntityKey related exceptions. Can someone point me to a good tutorial/example of how to update EF 4 entities using a repository class, called by an MVC front-end? Cheers. Jas.

  • INSERT INTO table doesn't work???

    - by Joann
    I found a tutorial from nettuts and it has a source code in it so tried implementing it in my site.. It is working now. However, it doesn't have a Registration system so I am making one. The thing is, as I have expected, my code is not working... It doesn't seem to know how to INSERT into the database. Here's the function that inserts data into the db. function register_User($un, $email, $pwd) { $query = "INSERT INTO users( username, password, email ) VALUES(:uname, :pwd, :email) LIMIT 1"; if($stmt = $this->conn->prepare($query)) { $stmt->bind_param(':uname', $un); $stmt->bind_param(':pwd', $pwd); $stmt->bind_param(':email', $email); $stmt->execute(); if($stmt->fetch()) { $stmt->close(); return true; } else return "The username or email you entered is already in use..."; } } I have debugged the connection to the database from within the class, it says it's connected. I tried using this method instead: function register($un, $email, $pwd) { $registerquery = $this->conn->query( "INSERT INTO users(uername, password, email) VALUES('".$un."', '".$pwd."', '".$email."')"); if($registerquery) { echo "<h4>Success</h4>"; } else { echo "<h4>Error</h4>"; } } And it echos "Error"... Can you please help me pen point the error in this??? :(

  • custom rss feed suddenly does not work anymore

    - by krike
    I just don't understand what's happening, I haven't change anything to the site for a few months but now suddenly the rss feed doesn't work anymore. I create a php file with the following code: header('Content-type: text/xml'); include("config/config.inc.php"); $result = mysqli_query($link, "SELECT * FROM tutorials ORDER BY tutorial_id DESC LIMIT 50"); ?> <rss version="2.0"> <channel> <title>CMS tutorial site</title> <description>Bringing you the best CMS tutorials from the web</description> <link>http://cmstutorials.org</link> <?php while($row = mysqli_fetch_object($result)) { $user = mysqli_fetch_object(mysqli_query($link, "SELECT * FROM user_extra WHERE userid=".$row->user_id."")); ?> <item> <title><?php echo $row->title; ?></title> <author><?php echo $user->username; ?></author> <description><?php echo $row->description; ?></description> <pubDate><?php echo $row->date; ?></pubDate> <link>http://cmstutorials.org/view_tutorial.php?tutorial_id=<?php echo $row->tutorial_id; ?></link> </item> <?php } ?> </channel> </rss> I checked the query by executing it in phpmyadmin and it works, doesn't give any error.

  • A trivial Python SWIG error question

    - by Alex
    I am trying to get Python running with swig to do C/C++. I am running the tutorial here, 'building a python module'. When I do the call gcc -c example.c example_wrap.c -I /my_correct_path/python2.5 I get an error: my_correct_path/python2.5/pyport.h:761:2: error: #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)." example_wrap.c: In function 'SWIG_Python_ConvertFunctionPtr': example_wrap.c:2034: warning: initialization discards qualifiers from pointer target type example_wrap.c: In function 'SWIG_Python_FixMethods': example_wrap.c:3232: warning: initialization discards qualifiers from pointer target type It actually does create an example.o file, but it doesn't work. I am using python2.5 not 2.1 as in the example, is this a problem? The error (everything else is just a 'warning') says something about wrong platform. This is a 64bit machine; is this a problem? Is my gcc configured wrong for my machine? How do I get past this? UPDATE: I am still having problems. How do I actually implement this "fix"?

  • Retrieve the Value of An Integer Variable

    - by Abluescarab
    This is probably easily figured out (I feel very stupid right now), but I can't find a solution anywhere, for some reason. Perhaps I'm not searching for the right thing. And maybe it's in some beginner tutorial I haven't watched. Anyway, I was wondering how to retrieve the value of an integer variable in C++? I know you can use cin.getline() for string variables, but I received an error message when I attempted that with an integer variable (and rightfully so, I know it was wrong, but I was looking for a solution). My project is a Win32 console application. What I'm trying to do is ask a user to input a number, stored in the variable n. Then I take the value of n and perform various math functions with it. In my header file, I have string, windows, iostream, stdio, math, and fstream. Do I need to add another library? There's not much more to tell. I can post my code if I must. EDIT: cout << "TEST SINE"; cout << "\nPlease enter a number.\n\n"; cin >> n; break; Here's the code I'm trying to use. Is this all I need to do? If so, how do I incorporate the variable so I can test it using sin, cos, and tan? Yet again, thanks ahead of time.

  • How to use boost::transform_iterator to iterate over modifed std::map values?

    - by Frank
    I have an std::map, and I would like to define an iterator that returns modified values. Typically, a std::map<int,double>::iterator iterates over std::pair<int,double>, and I would like the same behavior, just the double value is multiplied by a constant. I tried it with boost::transform_iterator, but it doesn't compile: #include <map> #include <boost/iterator/transform_iterator.hpp> #include <boost/functional.hpp> typedef std::map<int,double> Map; Map m; m[100] = 2.24; typedef boost::binder2nd< std::multiplies<double> > Function; typedef boost::transform_iterator<Function, Map::value_type*> MultiplyIter; MultiplyIter begin = boost::make_transform_iterator(m.begin(), Function(std::multiplies<double>(), 4)); // now want to similarly create an end iterator // and then iterate over the modified map The error is: error: conversion from 'boost ::transform_iterator< boost::binder2nd<multiplies<double> >, gen_map<int, double>::iterator , boost::use_default, boost::use_default >' to non-scalar type 'boost::transform_iterator< boost::binder2nd<multiplies<double> >, pair<const int, double> * , boost::use_default, boost::use_default >' requested What is gen_map and do I really need it? I adapted the transform_iterator tutorial code from here to write this code ...

Key = $ 1 Then in php: index.php --- $Key=$ _GET ['key']; if ($key == 'home') { include ('index.php'); // Home page } else if ($ key == 'software') { include ('software.php'); // } else if ($ key == 'webdesign') { include ('webdesign.php'); // } The problem is: When I implemented the menu software.php index.php to call the page: www.abelputra.com/index.php?key=software what happens is the page that is shown is two pages later software.php index.php page underneath. Is it because calling functions "include ()"? index.php structures: Header Content - contains the opening words Footer software.php structure: Header Content - contains an explanation of my software Footer Sorry my english bad. im from Indonesia.

  • Is Google Mock a good mocking framework ?

    - by des4maisons
    I am pioneering unit testing efforts at my company, and need need to choose a mocking framework to use. I have never used a mocking framework before. We have already chosen Google Test, so using Google Mock would be nice. However, my initial impressions after looking at Google Mock's tutorial are: The need for re-declaring each method in the mocking class with a MOCK_METHODn macro seems unnecessary and seems to go against the DRY principle. Their matchers (eg, the '_' in EXPECT_CALL(turtle, Forward(_));) and the order of matching seem almost too powerful. Like, it would be easy to say something you don't mean, and miss bugs that way. I have high confidence in google's developers, and low confidence in my own ability to judge mocking frameworks, never having used them before. So my question is: Are these valid concerns? Or is there no better way to define a mock object, and are the matchers intuitive to use in practice? I would appreciate answers from anyone who has used Google Mock before, and comparisons to other C++ frameworks would be helpful.

  • How to update a Widget dynamically (Not waiting 30 min for onUpdate to be called)?

    - by Donal Rafferty
    I am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidgetProvider{ RemoteViews remoteViews; AppWidgetManager appWidgetManager; ComponentName thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Timer timer = new Timer(); timer.scheduleAtFixedRate(new WlanTimer(context, appWidgetManager), 1, 10000); } private class WlanTimer extends TimerTask{ RemoteViews remoteViews; AppWidgetManager appWidgetManager; ComponentName thisWidget; public WlanTimer(Context context, AppWidgetManager appWidgetManager) { this.appWidgetManager = appWidgetManager; remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); thisWidget = new ComponentName(context, WlanWidget.class); wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); } @Override public void run() { remoteViews.setTextViewText(R.id.widget_textview, wifiManager.getConnectionInfo().getSSID()); appWidgetManager.updateAppWidget(thisWidget, remoteViews); } } The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask? (Avoid polling) UPDATE As per Karan's suggestion I have added the following code in my Service: RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); ComponentName thisWidget = new ComponentName( context, WlanWidget.class ); remoteViews.setTextViewText(R.id.widget_QCLevel, " " + qcPercentage); AppWidgetManager.getInstance( context ).updateAppWidget( thisWidget, remoteViews ); This gets run everytime the RSSI level changes but it still never updates the TextView on my widget, any ideas why?

  • GWT with JPA - no persistence provider...

    - by meliniak
    GWT with JPA There are two projects in my eclipse workspace, let's name them: -JPAProject -GWTProject JPAProject contains JPA configuration stuff (persistence.xml, entity classes and so on). GWTProject is an examplary GWT project (taken from official GWT tutorial). Both projects work fine alone. That is, I can create EMF (EntityManagerFactory) in JPAProject and get entities from the database. GWTProject works fine too, I can run it, fill the field text in the browser and get the response. My goal is to call JPAProject from GWTProject to get entities. But the problem is that when calling DAO, I get the following exception: [WARN] Server class 'com.emergit.service.dao.profile.ProfileDaoService' could not be found in the web app, but was found on the system classpath [WARN] Adding classpath entry 'file:/home/maliniak/workspace/emergit/build/classes/' to the web app classpath for this session [WARN] /gwttest/greet javax.persistence.PersistenceException: No Persistence provider for EntityManager named emergitPU at javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at com.emergit.service.dao.profile.JpaProfileDaoService.<init>(JpaProfileDaoService.java:19) at pl.maliniak.server.GreetingServiceImpl.<init>(GreetingServiceImpl.java:21) . . . at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:380) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:395) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:488) [ERROR] 500 - POST /gwttest/greet (127.0.0.1) 3812 bytes I guess that the warnings at the beginning can be omitted for now. Do you have any ideas? I guess I am missing some basic point. All hints are highly apprecieable.

  • How to hide div serverside by reading cookie

    - by user338109
    I am using following a tutorial from here: http://www.shopdev.co.uk/blog/cookies-with-jquery-designing-collapsible-layouts/ This is the script I use: <script type="text/javascript" language="javascript"> $(function() { // SETUP: // When the info banner is clicked: $('#setup').click(function() { $('#intro').css("display","none"); $.cookie('intro', 'collapsed'); }); // COOKIES // Info banner state var intro = $.cookie('intro'); // READ THE COOKIES if (intro == 'collapsed') { $('#intro').css("display","none"); }; }); </script> The script hides the following div as the cookie is read: <div class="feedback attention" id="intro"> Text goes here <a id="setup" href="#">Ok I get it, please hide this</a> </div> Everything work great but when the page loads the div is shown for a split second. I guess the solution is to present two different pieces of markup serverside according to the cookie info. I have no idea how to go about this.

  • Load more function in Javascript

    - by erastusnjuki
    EDIT: This question was initially too general, I think. So What I really need is a very good tutorial on how to implement the Load More function on Safari for iPhone just like the Twitter website(mobile.twitter.com) does. Just a wordpress plugin won't really help. But if the plugin is well explained, like if it is wptouch, home(that also has this function) that can also do. I know that it doesn't really matter that it is being displayed on a mobile device, but the point I am stressing is that if such a function is well explained, then it will be up to me to know how to customize it to suit me. I am using a javascript function to load entries that come from the database dynamically, so that content opens in the same page (like with twitter(tweets feed) and facebook(news feed)). The php/html version(That opens a page in a new tab) is echo '<a href="http://'. $_SERVER['HTTP_HOST'] .'/'.$domain_page.'?form='.$form_id.'&page='.($page+1).'">Load more entries&rsaquo; </a>'; The javascript/ajax version: <div id="call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="ajax-load-more"> <img id="spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="spin" src="<?php bloginfo('template_directory'); ?>/images/main-ajax-loader.gif" style="display:none" alt="" /> <a class="ajax" href="javascript:$ajax_hv('#spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeIn(200); $ajax_hv('#ajaxentries_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').load('form='<? echo $form_id; ?>&page=<?php echo $page+1;?>', {}, function(){ $ajax_hv('#call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeOut();})">Load more entries... </a>

  • How do I implement a collection in Scala 2.8?

    - by Simon Reinhardt
    In trying to write an API I'm struggling with Scala's collections in 2.8(.0-beta1). Basically what I need is to write something that: adds functionality to immutable sets of a certain type where all methods like filter and map return a collection of the same type without having to override everything (which is why I went for 2.8 in the first place) where all collections you gain through those methods are constructed with the same parameters the original collection had (similar to how SortedSet hands through an ordering via implicits) which is still a trait in itself, independent of any set implementations. Additionally I want to define a default implementation, for example based on a HashSet. The companion object of the trait might use this default implementation. I'm not sure yet if I need the full power of builder factories to map my collection type to other collection types. I read the paper on the redesign of the collections API but it seems like things have changed a bit since then and I'm missing some details in there. I've also digged through the collections source code but I'm not sure it's very consistent yet. Ideally what I'd like to see is either a hands-on tutorial that tells me step-by-step just the bits that I need or an extensive description of all the details so I can judge myself which bits I need. I liked the chapter on object equality in "Programming in Scala". :-) But I appreciate any pointers to documentation or examples that help me understand the new collections design better.

"'"; $sql = mysql_query ( $query ); if ( $result = mysql_fetch_array ( $sql ) ) { /* Extract the variables for sending in our server response */ $news_item['news_id'] = $result['news_id']; $news_item['date'] = XMLRPC_convert_timestamp_to_iso8601( mysql_datetime_to_timestamp( $result['date'] ) ); $news_item['title'] = $result['title']; $news_item['full_desc'] = $result['full_desc']; $news_item['author'] = $result['author']; /* Respond to the client with the news item */ XMLRPC_response(XMLRPC_prepare($news_item), KD_XMLRPC_USERAGENT); } else { /* If there was an error, respond with a fault code instead */ XMLRPC_error("1", "news_viewNewsItem() error: Unable to read news:" . mysql_error(), KD_XMLRPC_USERAGENT); } } In server.py file there is functions for every method but I dont know how to write in php server: def add(self, x, y): print print "input x=%s, y=%s" % (str(x), str(y)) sum = x + y print "output", sum print return sum Can some one help me with code , and tell me how to handle various types from client to server?? Thanks and Happy New Year

  • Getting a gestureoverlayview

    - by Codejoy
    I have been using some nice tutorials on drawing graphics on my android. I wanted to also add in the cool gesture demo found here: http://developer.android.com/resources/articles/gestures.html That takes these lines of code: GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); This is fine and dandy yet I realize in my demo i'm trying to build using code from "Playing with Graphics in Android". The demos make sense, everything makes sense but I found out by using: setContentView(new Panel(this)); as is required by the Playing With Graphics tutorials, then the findViewById seems to no longer be valid and returns null. At first I was about to post a stupider question as to why this is happening, a quick test of playing with the setContentView made me realize the cause of findViewById returning null, I just do not know how to remedy this issue. Whats the key I am missing here? I realize that the new Panel is doinking some reference up but I am not sure how to make the connection here. The: R.id.gestures is defined right int he main.xml as: (just like the tutorial) <android.gesture.GestureOverlayView android:id="@+id/gestures" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" /> So I did confirm the setContentView(new Panel(this)) is causing the issue. So I know the issue is that I have to figure out how to add the android.gesture.GestureOverlayView to the panel class somehow, I am just not sure how to go about this. After fighting with this I generally know what I need to do just now how to do it. I think I need either the equivalent of creating a panel in that main.xml OR figuring out how to build whats in main.xml for the gestures in code. I am close because I did this: GestureOverlayView gestures = new GestureOverlayView(this); which gets me a non null gestures now, unfortunately since I am not telling it to fill Parent anywhere I don't think its really showing up, so I am trying hard to figure out layout pa rams. Am I even on the right track?

  • How to use Enquire.Js?

    - by big_smile
    Enquire.js is a Javascipt that re-creates CSS media queries for Javascripts. This means you can wrap your Javascripts in Media Queries. (Just like you would wrap CSS in Media Queries). I'm not quite sure how to use it. This tutorial says this: enquire.register("max-width: 960px", function() { // put your code here }); However, when I follow that, my code stops working. Here is an example of some Jquery Tabs without Enquire.JS. It works fine. Here are the same tabs, but with Enquire.JS added. Now it stops working. I've experimented with different variations of the code, but none of them work. What am I doing wrong? I think you might have place the Jquery Tab code in a separate file and then link to that file from within Enquire.Js, but I'm not sure how you would do that. (Although it would be handy to know as I'd imagine it would let you keep your scripts be more reusable). PS. This is not a criticism of Enquire.Js. I know that the problem lies squarely with my lack of proficiency in Javascript! I did spend a couple of hours searching for a solution, but couldn't find anything. Thanks for any help!

  • error catching exception while System.out.print

    - by user1702633
    I have 2 classes, one that implements a double lookup( int i); and one where I use that lookup(int i) in solving a question, or in this case printing the lookup values. This case is for an array. So I read the exception documentation or google/textbook and come with the following code: public double lookup(int i) throws Exception { if( i > numItems) throw new Exception("out of bounds"); return items[i]; } and take it over to my class and try to print my set, where set is a name of the object type I define in the class above. public void print() { for (int i = 0; i < set.size() - 1; i++) { System.out.print(set.lookup(i) + ","); } System.out.print(set.lookup(set.size())); } I'm using two print()'s to avoid the last "," in the print, but am getting an unhandled exception Exception (my exception's name was Exception) I think I have to catch my exception in my print() but cannot find the correct formatting online. Do I have to write catch exception Exception? because that gives me a syntax error saying invalid type on catch. Sources like http://docs.oracle.com/javase/tutorial/essential/exceptions/ are of little help to me, I'm can't seem to grasp what the text is telling me. I'm also having trouble finding sources with multiple examples where I can actually understand the coding in the examples. so could anybody give me a source/example for the above catch phrase and perhaps a decent source of examples for new Java programmers? my book is horrendous and I cannot seem to find an understandable example for the above catch phrase online.

  • How Many States Does an Activity Have?

    - by Android Eve
    The Activity lifecycle section in the Application Fundamentals tutorial states that there are 3 states: An activity has essentially three states: (1. active/running 2. paused 3. stopped) But then as I continued reading the actual Activity class documentation, the Activity Lifecycle section states that there are 4 state: An activity has essentially four states: (1. active/running 2. paused 3. stopped 4. "dropped"?) Both sources (on the same website) agree about the first 3, but the 4th one is only mentioned in the class documentation and is unnamed. So, are there really 4 states or only 3? If there are 4, what is the name of the 4th one? Please help me understand this discrepancy. Also, highlighted colored blocks in this beautiful and very informative flowchart don't seem to correspond to the states. Where, in the flowchart, would you mark the 3 or 4 states?
