Get to know what HTML-button is clicked with PHP, no Name of value available

- by koko

I have a wizard with 4 steps and in one of the steps, you can add items. By default, there are 3 time 5 empty input-fields listed. When you click a button, there have to be added some more. The 3 times 5 fields are added by a loop. How can I determine where I have to add some fields (in the first 5 field of the second or the third). I can't use another name for every button, because sometimes there can be more then 3 groups of 5 fields. In my code (PHP), I use the name of the button to know what happened in the form, so the name can't be different for the button in every group ... Further, the whole step is 1 form, so the post can't go to another script ... The value of the button has to be the same for every group. I've been thinking on possible solutions and these came up: On click a javascript adds a value to the post (in a hidden field?) But is this posted with the form? Could it be possible to get the ID of the clicked button? This might be different :-) I need a refresh after the click, so pure javascript isn't a solution either ... It is a very specific question, but I hope someone can give me some direction. Here is the code I'm talking about: <h3><label class="list_list:table_title">Eten</label></h3> <table id="eten"> <thead> <tr> <th>Naam item</th> <th>Aantal</th> </tr> </thead> <tbody> <tr> <td class="item"><input type="text" name="item_1_1" value="" class="inputText" maxlength="64" size="46" tabindex="11"/></td> <td class="amount"><input type="text" name="amount_1_1" value=""

PHP Form Sending Information to Limbo!

- by drew

I was told my client's quote form has not been generating very many emails. I have learned that although the form brings you to a confirmation page, the information never reaches the recipient. I have altered the code so it goes to my office email for testing purposes. If I post code for the form elements below, would someone be able to spot what the problem might be? Thank you very much! Link to the quote page is http://autoglass-plus.com/quote.php First is the form itself: <form id="quoteForm" name="form" action="form/index.php" method="post"> <fieldset> <p> <strong>Contact Information:</strong><br /> </p> <div> <label for="firstname">First Name:<br /> </label> <input type="text" size="30" name="firstname" class="txt" id="firstname" /> </div> <div> <label for="lastname">Last Name:<br /> </label> <input type="text" size="30" name="lastname" class="txt" id="lastname" /> </div> <div> <label for="address">Address:<br /> </label> <input type="text" size="30" name="address" class="txt" id="address" /> </div> <div> <label for="city">City:<br /> </label> <input type="text" size="30" name="city" class="txt" id="city" /> </div> <div> <label for="state">State:<br /> </label> <input type="text" size="30" name="state" class="txt" id="state" /> </div> <div> <label for="zip">Zip:<br /> </label> <input type="text" size="30" name="zip" class="txt" id="zip" /> </div> <div> <label for="label">Phone:<br /> </label> <input type="text" size="30" name="phone" class="txt" id="label" /> </div> <div> <label for="email">Email:<br /> </label> <input type="text" size="30" name="email" class="txt" id="email" /> </div> <p><br /> <b>Insurace Information</b></p> <p><i>Auto Glass Plus in an Approved Insurance Vendor.

Bi-directional WCF Client-Server Communication

- by Bill

I have been working for weeks on creating a client/server to control a music-server application located on the server-side that is controlled by several client apps located across the LAN. I've been successful in getting the client-side to communicate with the Server, sending commands to operate the music-server, and through the use of callbacks, reply to the clients so that all of the client UI's can be appropriately updated. My problem is however, that I unable to figure-out how to broadcast other messages that need to be sent from the server app to the clients. I was hoping to utilize the callback method; however I have not been able to access it from the server side. Do I need to modify or create another contract that provides for communication from the server to the clients? Does the binding require modification? As I mentioned earlier, I have truly been working on this for weeks (which is beginning to feel like 'years'), and hope to get this last piece of the application working. Would someone please steer me in the right direction?

How to retrive message list from p2p

- by cre-johnny07

Hello friends I have a messaging system that uses p2p. Each peer has a incoming message list and a outgoing message list. What I need to do is whenever a new peer will join the mesh he will get the all the incoming messages from other peers and add those into it's own incoming message list. Now I know when I get the other peer info from I can ask them to give their own list to me. But I'm not finding the way how..? Any suggestion on this or help would be highly appreciated. I'm giving my code below.

How to find an entry-level job after you already have a graduate degree?

- by Uri

Note: I asked this question in early 2009. A couple of months later, I found a great job. I've previously updated this question with some tips for whoever ends up in a similar situation, and now cleaned it up a little for the benefit of the fresh batch of graduates. Original post: In my early 20s I abandoned a great C++ development career path in a major company to go to graduate school and get a research masters (3 years). I did another year in industrial research, and then moved to the US to attend graduate school again, getting another masters and a Ph.D in software engineering from a top school (another 6 years down the drain). I was coding the whole way throughout my degrees (core Java and Eclipse plug-ins) and working on research related to software engineering (usability of APIs). I ended up graduating the year of the recession, with a son on the way and the prospects of no healthcare. Academic jobs and industrial research jobs are quite scarce. Initially, I was naive, thinking that with my background, I could easily find a coding job. Big mistake. It turns out that I'm in a complicated position. Entry level positions are usually offered to college undergraduates. I attended my school's career fairs, but you could immediately see signs of Ph.D. aversion and overqualification issues. Some of the recruiters I spoke with explicitly told me that they wanted 20 year olds with clean slates, and some were looking for interns since they are in various forms of hiring freezes. I managed to get a couple of interviews from these career fairs and through recruiters. However, since I've been out of school for a long time and programming primarily in Java, I am also no longer proficient in C/C++ and the usual range of college-level interview questions that everyone uses. I had no problems with this when I was 19 and interviewing for my first job since a lot of what you do in C is manipulate pointers and I was coding C++ for fun and for school. Later I was routinely doing pointer manipulation on the job, and during my first masters taught college courses with data structures and C++. But even though I remember many properties of C++ well, it's been close to ten years since I regularly used C++ and pointers. As a Java developer I rarely had to work at this level, but experience in OOD and in writing good maintainable code is meaningless for C++ interviews. Reading books as a refresh and looking at sample code did not do the trick. I also looked at mid-to-senior level Java positions, but most of them focused on J2EE APIs rather than on core Java and required a certain number of years in industrial positions. Coding research tools and prior C++ experience doesn't count. So that sends me back to entry-level jobs that are posted through job-boards, and these are not common (mostly they are Monster junk), and small companies are even less likely to answer a Ph.D. compared to the giants who participate in top-10 career fairs. Even worse, in many companies initial screening is done by HR folks who really don't want to deal with anything anomalous like a Ph.D. Any tips on how I should approach this intractable position? For example, what should I write in cover letters? Note that while immigration is not an issue for me, I cannot go freelance as I need the benefits (and in particular group health insurance). During my studies I had no time to contribute to open-source projects or maintain a popular blog, so even if I invested in that now there would be no immediate benefit. Updates: In the two months after posting this I received several offers to work as a core Java developer in the financial industry and accepted one from a firm where I am working to this day. For those who find themselves in similar situations, here are my tips: Give up on trying to find an entry level positions. You can't undo time. Accept the fact that there is Ph.D. discrimination in the job market (some might say rightfully so). It is legal to discriminate based on education. No point fighting it. The most important tip is to focus on the language you are comfortable with. The sad truth about programming in a particular language is that it is not like riding a bike. If you haven't used a language in the last few years, and can't actually apply it routinely (not just as a refresher) before you start your search, it is going to be very difficult to do well in an interview. Now that I'm interviewing others, I routinely see it in folks with a mixed C++/Java background. We maintain "a shadow" of the old language but end up with a weird mix that makes it hard to interview on either. Entry-level folks are at an advantage here since they usually have one language. Memory can help you do great in a screening interview, but without recent day-to-day experience, code tests will be difficult. Despite the supposed relation, core Java programming and J2EE programming are two different things with different skillsets. If you come from academia, you likely have very little J2EE experience and may find it hard to get accepted for a J2EE job. J2EE jobs seem to have a larger list of acronyms in their requirements. In addition, from interviewing J2EE developers it seems that for many there is a focus on mastering specific APIs and architectures, whereas core Java development tends to be secondary. In the same way that I can no longer manipulate pointers well, a J2EE developer may have difficulties doing low level Java manipulation. This puts you at a relative advantage in competing for core Java jobs! If you are able to work for startups (in terms of family life and stability) or migrate to startup-rich areas such as the west coast, you can find many exciting opportunities where advanced degrees are a benefit. I've since been approached by several startups, although I had to decline. Work through a recruiter if possible. They have direct contacts with the hiring parties, allowing you to "stand out". It is better to get a clear yes/no confirmation from a recruiter on whether a company might be interested in interviewing you, than it is to send your resume and hope that someone will ever see it. Recruiters are also a great way of bypassing HR. However, also beware of recruiters. They have a vested interest and will go to various shady practices and pressure tactics. To find a good recruiter, talk to a friend who declined a job offer he got through a recruiter. A good recruiter, to me, is measured in how they handle that. Interview for the jobs that require your core strength. If you're rusty or entirely unfamiliar with a technology around which the job revolves, you're probably not a good match. Yes, you probably have the talent to master them, but most companies would want "instant gratification". I got my offers from companies that wanted core Java developer. I didn't do well on places that wanted advance C++ because I am too rusty and not up to date on recent libraries. I also didn't hear from companies that wanted lots of J2EE experience, and that's ok. Finding companies that want core Java without web is harder, but exists in specific industries (e.g., finance, defense). This requires a lot more legwork in terms of search, but these jobs do exist. There are different interview styles. Some companies focus on puzzles, some companies focus on algorithms, and some companies focus on design and coding skills. I had the most success in places where the questions were the most related to the function I would have been performing. Pick companies accordingly as well.

During Spring unit test, data written to db but test not seeing the data

- by richever

I wrote a test case that extends AbstractTransactionalJUnit4SpringContextTests. The single test case I've written creates an instance of class User and attempts to write it to the database using Hibernate. The test code then uses SimpleJdbcTemplate to execute a simple select count(*) from the user table to determine if the user was persisted to the database or not. The test always fails though. I was suspect because in the Spring controller I wrote, the ability to save an instance of User to the db is successful. So I added the Rollback annotation to the unit test and sure enough, the data is written to the database since I can even see it in the appropriate table -- the transaction isn't rolled back when the test case is finished. Here's my test case: @ContextConfiguration(locations = { "classpath:context-daos.xml", "classpath:context-dataSource.xml", "classpath:context-hibernate.xml"}) public class UserDaoTest extends AbstractTransactionalJUnit4SpringContextTests { @Autowired private UserDao userDao; @Test @Rollback(false) public void teseCreateUser() { try { UserModel user = randomUser(); String username = user.getUserName(); long id = userDao.create(user); String query = "select count(*) from public.usr where usr_name = '%s'"; long count = simpleJdbcTemplate.queryForLong(String.format(query, username)); Assert.assertEquals("User with username should be in the db", 1, count); } catch (Exception e) { e.printStackTrace(); Assert.assertNull("testCreateUser: " + e.getMessage()); } } } I think I was remiss by not adding the configuration files. context-hibernate.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd> <bean id="namingStrategy" class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean"> <property name="staticField"> <value>org.hibernate.cfg.ImprovedNamingStrategy.INSTANCE</value> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" destroy-method="destroy" scope="singleton"> <property name="namingStrategy"> <ref bean="namingStrategy"/> </property> <property name="dataSource" ref="dataSource"/> <property name="mappingResources"> <list> <value>com/company/model/usr.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.use_sql_comments">true</prop> <prop key="hibernate.query.substitutions">yes 'Y', no 'N'</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.use_minimal_puts">false</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.current_session_context_class">thread</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> <property name="nestedTransactionAllowed" value="false" /> </bean> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager"> <ref local="transactionManager"/> </property> <property name="transactionAttributes"> <props> <prop key="create">PROPAGATION_REQUIRED</prop> <prop key="delete">PROPAGATION_REQUIRED</prop> <prop key="update">PROPAGATION_REQUIRED</prop> <prop key="*">PROPAGATION_SUPPORTS,readOnly</prop> </props> </property> </bean> </beans> context-dataSource.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="org.postgresql.Driver" /> <property name="jdbcUrl" value="jdbc\:postgresql\://localhost:5432/company_dev" /> <property name="user" value="postgres" /> <property name="password" value="postgres" /> </bean> </beans> context-daos.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="extendedFinderNamingStrategy" class="com.company.dao.finder.impl.ExtendedFinderNamingStrategy"/> <bean id="finderIntroductionAdvisor" class="com.company.dao.finder.impl.FinderIntroductionAdvisor"/> <bean id="abstractDaoTarget" class="com.company.dao.impl.GenericDaoHibernateImpl" abstract="true" depends-on="sessionFactory"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> <property name="namingStrategy"> <ref bean="extendedFinderNamingStrategy"/> </property> </bean> <bean id="abstractDao" class="org.springframework.aop.framework.ProxyFactoryBean" abstract="true"> <property name="interceptorNames"> <list> <value>transactionInterceptor</value> <value>finderIntroductionAdvisor</value> </list> </property> </bean> <bean id="userDao" parent="abstractDao"> <property name="proxyInterfaces"> <value>com.company.dao.UserDao</value> </property> <property name="target"> <bean parent="abstractDaoTarget"> <constructor-arg> <value>com.company.model.UserModel</value> </constructor-arg> </bean> </property> </bean> </beans> Some of this I've inherited from someone else.

Android remote service doesn't call service methods

- by tarantel

Hello, I'm developing a GPS tracking software on android. I need IPC to control the service from different activities. So I decide to develop a remote service with AIDL. This wasn't a big problem but now it's always running into the methods of the interface and not into those of my service class. Maybe someone could help me? Here my ADIL file: package test.de.android.tracker interface ITrackingServiceRemote { void startTracking(in long trackId); void stopTracking(); void pauseTracking(); void resumeTracking(in long trackId); long trackingState(); } And the here a short version of my service class: public class TrackingService extends Service implements LocationListener{ private LocationManager mLocationManager; private TrackDb db; private long trackId; private boolean isTracking = false; @Override public void onCreate() { super.onCreate(); mNotificationManager = (NotificationManager) this .getSystemService(NOTIFICATION_SERVICE); mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE); db = new TrackDb(this.getApplicationContext()); } @Override public void onStart(Intent intent, int startId) { super.onStart(intent, startId); } @Override public void onDestroy(){ //TODO super.onDestroy(); } @Override public IBinder onBind(Intent intent){ return this.mBinder; } private IBinder mBinder = new ITrackingServiceRemote.Stub() { public void startTracking(long trackId) throws RemoteException { TrackingService.this.startTracking(trackId); } public void pauseTracking() throws RemoteException { TrackingService.this.pauseTracking(); } public void resumeTracking(long trackId) throws RemoteException { TrackingService.this.resumeTracking(trackId); } public void stopTracking() throws RemoteException { TrackingService.this.stopTracking(); } public long trackingState() throws RemoteException { long state = TrackingService.this.trackingState(); return state; } }; public synchronized void startTracking(long trackId) { // request updates every 250 meters or 0 sec this.trackId = trackId; mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 250, this); isTracking = true; } public synchronized long trackingState() { if(isTracking){ return trackId; } else return -1; } public synchronized void stopTracking() { if(isTracking){ mLocationManager.removeUpdates(this); isTracking = false; } else Log.i(TAG, "Could not stop because service is not tracking at the moment"); } public synchronized void resumeTracking(long trackId) { if(!isTracking){ this.trackId = trackId; mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 250, this); isTracking = true; } else Log.i(TAG, "Could not resume because service is tracking already track " + this.trackId); } public synchronized void pauseTracking() { if(isTracking){ mLocationManager.removeUpdates(this); isTracking = false; } else Log.i(TAG, "Could not pause because service is not tracking at the moment"); } public void onLocationChanged(Location location) { //TODO } For easier access from the client I wrote a ServiceManager class which sets up the ServiceConnection and you can call the service methods. Here my code for this: public class TrackingServiceManager{ private static final String TAG = "TrackingServiceManager"; private ITrackingServiceRemote mService = null; private Context mContext; private Boolean isBound = false; private ServiceConnection mServiceConnection; public TrackingServiceManager(Context ctx){ this.mContext = ctx; } public void start(long trackId) { if (isBound && mService != null) { try { mService.startTracking(trackId); } catch (RemoteException e) { Log.e(TAG, "Could not start tracking!",e); } } else Log.i(TAG, "No Service bound! 1"); } public void stop(){ if (isBound && mService != null) { try { mService.stopTracking(); } catch (RemoteException e) { Log.e(TAG, "Could not stop tracking!",e); } } else Log.i(TAG, "No Service bound!"); } public void pause(){ if (isBound && mService != null) { try { mService.pauseTracking(); } catch (RemoteException e) { Log.e(TAG, "Could not pause tracking!",e); } } else Log.i(TAG, "No Service bound!"); } public void resume(long trackId){ if (isBound && mService != null) { try { mService.resumeTracking(trackId); } catch (RemoteException e) { Log.e(TAG, "Could not resume tracking!",e); } } else Log.i(TAG, "No Service bound!"); } public float state(){ if (isBound && mService != null) { try { return mService.trackingState(); } catch (RemoteException e) { Log.e(TAG, "Could not resume tracking!",e); return -1; } } else Log.i(TAG, "No Service bound!"); return -1; } /** * Method for binding the Service with client */ public boolean connectService(){ mServiceConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { TrackingServiceManager.this.mService = ITrackingServiceRemote.Stub.asInterface(service); } } @Override public void onServiceDisconnected(ComponentName name) { if (mService != null) { mService = null; } } }; Intent mIntent = new Intent("test.de.android.tracker.action.intent.TrackingService"); this.isBound = this.mContext.bindService(mIntent, mServiceConnection, Context.BIND_AUTO_CREATE); return this.isBound; } public void disconnectService(){ this.mContext.unbindService(mServiceConnection); this.isBound = false; } } If i now try to call a method from an activity for example start(trackId) nothing happens. The binding is OK. When debugging it always runs into the startTracking() in the generated ITrackingServiceRemote.java file and not into my TrackingService class. Where is the problem? I can't find anything wrong. Thanks in advance! Tobias

JavaFx 2.1, 2.2 TableView update issue

- by Lewis Liu

My application uses JPA read data into TableView then modify and display them. The table refreshed modified record under JavaFx 2.0.3. Under JavaFx 2.1, 2.2, the table wouldn't refresh the update anymore. I found other people have similar issue. My plan was to continue using 2.0.3 until someone fixes the issue under 2.1 and 2.2. Now I know it is not a bug and wouldn't be fixed. Well, I don't know how to deal with this. Following are codes are modified from sample demo to show the issue. If I add a new record or delete a old record from table, table refreshes fine. If I modify a record, the table wouldn't refreshes the change until a add, delete or sort action is taken. If I remove the modified record and add it again, table refreshes. But the modified record is put at button of table. Well, if I remove the modified record, add the same record then move the record to the original spot, the table wouldn't refresh anymore.

while I scroll between the layout it takes too long to be able to scroll between the gallerie's pictures. Is there any way to reduce this time?

- by Mateo

Hello, this is my first question here, though I've being reading this forum for quite a while. Most of the answers to my doubts are from here :) Getting back on topic. I'm developing an Android application. I'm drawing a dynamic layout that are basically Galleries, inside a LinearLayout, inside a ScrollView, inside a RelativeLayout. The ScrollView is a must, because I'm drawing a dynamic amount of galleries that most probably will not fit on the screen. When I scroll inside the layout, I have to wait 3/4 seconds until the ScrollView "deactivates" to be able to scroll inside the galleries. What I want to do is to reduce this time to a minimum. Preferably I would like to be able to scroll inside the galleries as soon as I lift my finger from the screen, though anything lower than 2 seconds would be great as well. I've being googling around for a solution but all I could find until now where layout tutorials that didn't tackle this particular issue. I was hoping someone here knows if this is possible and if so to give me some hints on how to do so. I would prefer not to do my own ScrollView to solve this. But if that is the only way I would appreciate some help because I'm not really sure how would I solve this issue by doing that. this is my layout: public class PicturesL extends Activity implements OnClickListener, OnItemClickListener, OnItemLongClickListener { private ArrayList<ImageView> imageView = new ArrayList<ImageView>(); private StringBuilder PicsDate = new StringBuilder(); private CaWaApplication application; private long ListID; private ArrayList<Gallery> gallery = new ArrayList<Gallery>(); private ArrayList<Bitmap> Thumbails = new ArrayList<Bitmap>(); private String idioma; private ArrayList<Long> Days = new ArrayList<Long>(); private long oldDay; private long oldThumbsLoaded; private ArrayList<Long> ThumbailsDays = new ArrayList<Long>(); private ArrayList<ArrayList<Long>> IDs = new ArrayList<ArrayList<Long>>(); @Override public void onCreate(Bundle savedInstancedState) { super.onCreate(savedInstancedState); RelativeLayout layout = new RelativeLayout(this); ScrollView scroll = new ScrollView(this); LinearLayout realLayout = new LinearLayout(this); ArrayList<TextView> texts = new ArrayList<TextView>(); Button TakePic = new Button(this); idioma = com.mateloft.cawa.prefs.getLang(this); if (idioma.equals("en")) { TakePic.setText("Take Picture"); } else if (idioma.equals("es")) { TakePic.setText("Sacar Foto"); } RelativeLayout.LayoutParams scrollLP = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT); layout.addView(scroll, scrollLP); realLayout.setOrientation(LinearLayout.VERTICAL); realLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); scroll.addView(realLayout); TakePic.setId(67); TakePic.setOnClickListener(this); application = (CaWaApplication) getApplication(); ListID = getIntent().getExtras().getLong("listid"); getAllThumbailsOfID(); LinearLayout.LayoutParams TakeLP = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); realLayout.addView(TakePic); oldThumbsLoaded = 0; int galler = 100; for (int z = 0; z < Days.size(); z++) { ThumbailsManager croppedThumbs = new ThumbailsManager(Thumbails, oldThumbsLoaded, ThumbailsDays.get(z)); oldThumbsLoaded = ThumbailsDays.get(z); texts.add(new TextView(this)); texts.get(z).setText("Day " + Days.get(z).toString()); gallery.add(new Gallery(this)); gallery.get(z).setAdapter(new ImageAdapter(this, croppedThumbs.getGallery(), 250, 175, true, ListID)); gallery.get(z).setOnItemClickListener(this); gallery.get(z).setOnItemLongClickListener(this); gallery.get(z).setId(galler); galler++; realLayout.addView(texts.get(z)); realLayout.addView(gallery.get(z)); } Log.d("PicturesL", "ListID: " + ListID); setContentView(layout); } private void getAllThumbailsOfID() { ArrayList<ModelPics> Pictures = new ArrayList<ModelPics>(); ArrayList<String> ThumbailsPath = new ArrayList<String>(); Pictures = application.dataManager.selectAllPics(); long thumbpathloaded = 0; int currentID = 0; for (int x = 0; x < Pictures.size(); x++) { if (Pictures.get(x).walkname == ListID) { if (Days.size() == 0) { Days.add(Pictures.get(x).day); oldDay = Pictures.get(x).day; IDs.add(new ArrayList<Long>()); currentID = 0; } if (oldDay != Pictures.get(x).day) { oldDay = Pictures.get(x).day; ThumbailsDays.add(thumbpathloaded); Days.add(Pictures.get(x).day); IDs.add(new ArrayList<Long>()); currentID++; } StringBuilder tpath = new StringBuilder(); tpath.append(Pictures.get(x).path.substring(0, Pictures.get(x).path.length() - 4)); tpath.append("-t.jpg"); IDs.get(currentID).add(Pictures.get(x).id); ThumbailsPath.add(tpath.toString()); thumbpathloaded++; if (x == Pictures.size() - 1) { Log.d("PicturesL", "El ultimo de los arrays, tamaño: " + Days.size()); ThumbailsDays.add(thumbpathloaded); } } } for (int y = 0; y < ThumbailsPath.size(); y++) { Thumbails.add(BitmapFactory.decodeFile(ThumbailsPath.get(y))); } } I had a memory leak on another activity when screen orientation changed that was making it slower, now it is working better. The scroller is not locking up. But sometimes, when it stops scrolling, it takes a few seconds (2/3) to disable itself. I just want it to be a little more dynamic, is there any way to override the listener and make it stop scrolling ON_ACTION_UP or something like that? I don't want to use the listview because I want to have each gallery separated by other views, now I just have text, but I will probably separate them with images with a different size than the galleries. I'm not really sure if this is possible with a listadapter and a listview, I assumed that a view can only handle only one type of object, so I'm using a scrollview of a layout, if I'm wrong please correct me :) Also this activity works as a preview or selecting the pictures you want to view in full size and manage their values. So its working only with thumbnails. Each one weights 40 kb. Guessing that is very unlikely that a user gets more than 1000~1500 pictures in this view, i thought that the activity wouldn't use more than 40~50 mb of ram in this case, adding 10 more if I open the fullsized view. So I guessed as well most devices are able to display this view in full size. If it doesn't work on low-end devices my plan was to add an option in the app preferences to let user chop this view according to some database values. And a last reason is that during most of this activity "life-cycle" (the app has pics that are relevant to the view, when it ends the value that selects which pictures are displayed has to change and no more pictures are added inside this instance of this activity); the view will be unpopulated, so most of the time showing everything wont cost much, just at the end of its cycle That was more or less what I thought at the time i created this layout. I'm open to any sort of suggestion or opinion, I just created this layout a few days ago and I'm trying to see if it can work right, because it suits my app needs. Though if there is a better way i would love to hear it Thanks Mateo

I got it from http://www.codingsanity.com/idnumber.htm : using System; using System.Text.RegularExpressions; namespace Utilities.SouthAfrica { /// <summary> /// Represents a South African Identity Number. /// valid number = 7707215230080 /// invalid test number = 1234567891234 /// /// </summary> [Serializable()] public class IdentityNumber { #region Enumerations /// <summary> /// Indicates a gender. /// </summary> public enum PersonGender { Female = 0, Male = 5 } public enum PersonCitizenship { SouthAfrican = 0, Foreign = 1 } #endregion #region Declarations static Regex _expression; Match _match; const string _IDExpression = @"(?<Year>[0-9][0-9])(?<Month>([0][1-9])|([1][0-2]))(?<Day>([0-2][0-9])|([3][0-1]))(?<Gender>[0-9])(?<Series>[0-9]{3})(?<Citizenship>[0-9])(?<Uniform>[0-9])(?<Control>[0-9])"; #endregion #region Constuctors /// <summary> /// Sets up the shared objects for ID validation. /// </summary> static IdentityNumber() { _expression = new Regex(_IDExpression, RegexOptions.Compiled | RegexOptions.Singleline); } /// <summary> /// Creates the ID number from a string. /// </summary> /// <param name="IDNumber">The string ID number.</param> public IdentityNumber(string IDNumber) { _match = _expression.Match(IDNumber.Trim()); } #endregion #region Properties /// <summary> /// Indicates the date of birth encoded in the ID Number. /// </summary> /// <exception cref="System.ArgumentException">Thrown if the ID Number is not usable.</exception> public DateTime DateOfBirth { get { if(IsUsable == false) { throw new ArgumentException("ID Number is unusable!", "IDNumber"); } int year = int.Parse(_match.Groups["Year"].Value); // NOTE: Do not optimize by moving these to static, otherwise the calculation may be incorrect // over year changes, especially century changes. int currentCentury = int.Parse(DateTime.Now.Year.ToString().Substring(0, 2) + "00"); int lastCentury = currentCentury - 100; int currentYear = int.Parse(DateTime.Now.Year.ToString().Substring(2, 2)); // If the year is after or at the current YY, then add last century to it, otherwise add // this century. // TODO: YY -> YYYY logic needs thinking about if(year > currentYear) { year += lastCentury; } else { year += currentCentury; } return new DateTime(year, int.Parse(_match.Groups["Month"].Value), int.Parse(_match.Groups["Day"].Value)); } } /// <summary> /// Indicates the gender for the ID number. /// </summary> /// <exception cref="System.ArgumentException">Thrown if the ID Number is not usable.</exception> public PersonGender Gender { get { if(IsUsable == false) { throw new ArgumentException("ID Number is unusable!", "IDNumber"); } int gender = int.Parse(_match.Groups["Gender"].Value); if(gender < (int) PersonGender.Male) { return PersonGender.Female; } else { return PersonGender.Male; } } } /// <summary> /// Indicates the citizenship for the ID number. /// </summary> /// <exception cref="System.ArgumentException">Thrown if the ID Number is not usable.</exception> public PersonCitizenship Citizenship { get { if(IsUsable == false) { throw new ArgumentException("ID Number is unusable!", "IDNumber"); } return (PersonCitizenship) Enum.Parse(typeof(PersonCitizenship), _match.Groups["Citizenship"].Value); } } /// <summary> /// Indicates if the IDNumber is usable or not. /// </summary> public bool IsUsable { get { return _match.Success; } } /// <summary> /// Indicates if the IDNumber is valid or not. /// </summary> public bool IsValid { get { if(IsUsable == true) { // Calculate total A by adding the figures in the odd positions i.e. the first, third, fifth, // seventh, ninth and eleventh digits. int a = int.Parse(_match.Value.Substring(0, 1)) + int.Parse(_match.Value.Substring(2, 1)) + int.Parse(_match.Value.Substring(4, 1)) + int.Parse(_match.Value.Substring(6, 1)) + int.Parse(_match.Value.Substring(8, 1)) + int.Parse(_match.Value.Substring(10, 1)); // Calculate total B by taking the even figures of the number as a whole number, and then // multiplying that number by 2, and then add the individual figures together. int b = int.Parse(_match.Value.Substring(1, 1) + _match.Value.Substring(3, 1) + _match.Value.Substring(5, 1) + _match.Value.Substring(7, 1) + _match.Value.Substring(9, 1) + _match.Value.Substring(11, 1)); b *= 2; string bString = b.ToString(); b = 0; for(int index = 0; index < bString.Length; index++) { b += int.Parse(bString.Substring(index, 1)); } // Calculate total C by adding total A to total B. int c = a + b; // The control-figure can now be determined by subtracting the ones in figure C from 10. string cString = c.ToString() ; cString = cString.Substring(cString.Length - 1, 1) ; int control = 0; // Where the total C is a multiple of 10, the control figure will be 0. if(cString != "0") { control = 10 - int.Parse(cString.Substring(cString.Length - 1, 1)); } if(_match.Groups["Control"].Value == control.ToString()) { return true; } } return false; } } #endregion } } Can someone please tell the syntax for how I pass an id number to the class?

Hello, I am trying to send a file from the phone running Android 1.5 to a server on a desktop. I wrote some code, which works on emulator, but on the phone it doesn't.

How do you convert a parent-child (adjacency) table to a nested set using PHP and MySQL?

- by mrbinky3000

I've spent the last few hours trying to find the solution to this question online. I've found plenty of examples on how to convert from nested set to adjacency... but few that go the other way around. The examples I have found either don't work or use MySQL procedures. Unfortunately, I can't use procedures for this project. I need a pure PHP solution. I have a table that uses the adjacency model below: id parent_id category 1 0 ROOT_NODE 2 1 Books 3 1 CD's 4 1 Magazines 5 2 Books/Hardcover 6 2 Books/Large Format 7 4 Magazines/Vintage And I would like to convert it to a Nested Set table below: id left right category 1 1 14 Root Node 2 2 7 Books 3 3 4 Books/Hardcover 4 5 6 Books/Large Format 5 8 9 CD's 6 10 13 Magazines 7 11 12 Magazines/Vintage Here is an image of what I need: I have a function, based on the pseudo code from this forum post (http://www.sitepoint.com/forums/showthread.php?t=320444) but it doesn't work. I get multiple rows that have the same value for left. This should not happen. <?php /** -- -- Table structure for table `adjacent_table` -- CREATE TABLE IF NOT EXISTS `adjacent_table` ( `id` int(11) NOT NULL AUTO_INCREMENT, `father_id` int(11) DEFAULT NULL, `category` varchar(128) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=8 ; -- -- Dumping data for table `adjacent_table` -- INSERT INTO `adjacent_table` (`id`, `father_id`, `category`) VALUES (1, 0, 'ROOT'), (2, 1, 'Books'), (3, 1, 'CD''s'), (4, 1, 'Magazines'), (5, 2, 'Hard Cover'), (6, 2, 'Large Format'), (7, 4, 'Vintage'); -- -- Table structure for table `nested_table` -- CREATE TABLE IF NOT EXISTS `nested_table` ( `id` int(11) NOT NULL AUTO_INCREMENT, `lft` int(11) DEFAULT NULL, `rgt` int(11) DEFAULT NULL, `category` varchar(128) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; */ mysql_connect('localhost','USER','PASSWORD') or die(mysql_error()); mysql_select_db('DATABASE') or die(mysql_error()); adjacent_to_nested(0); /** * adjacent_to_nested * * Reads a "adjacent model" table and converts it to a "Nested Set" table. * @param integer $i_id Should be the id of the "root node" in the adjacent table; * @param integer $i_left Should only be used on recursive calls.

INSERT INTO nested_table (id, lft, rgt, category) VALUES( NULL, '2', '5', 'Hard Cover' ) INSERT INTO nested_table (id, lft, rgt, category) VALUES( NULL, '2', '7', 'Large Format' ) INSERT INTO nested_table (id, lft, rgt, category) VALUES( NULL, '1', '8', 'Books' ) INSERT INTO nested_table (id, lft, rgt, category) VALUES( NULL, '1', '10', 'CD\'s' ) INSERT INTO nested_table (id, lft, rgt, category) VALUES( NULL, '10', '13', 'Vintage' ) INSERT INTO nested_table (id, lft, rgt, category) VALUES( NULL, '1', '14', 'Magazines' ) INSERT INTO nested_table (id, lft, rgt, category) VALUES( NULL, '0', '15', 'ROOT' ) As you can see, there are multiple rows sharing the lft value of "1" same goes for "2" In a nested-set, the values for left and right must be unique. Here is an example of how to manually number the left and right ID's in a nested set: UPDATE - PROBLEM SOLVED First off, I had mistakenly believed that the source table (the one in adjacent-lists format) needed to be altered to include a source node. This is not the case. Secondly, I found a cached page on BING (of all places) with a class that does the trick. I've altered it for PHP5 and converted the original author's mysql related bits to basic PHP. He was using some DB class. You can convert them to your own database abstraction class later if you want. Obviously, if your "source table" has other columns that you want to move to the nested set table, you will have to adjust the write method in the class below. Hopefully this will save someone else from the same problems in the future. <?php /** -- -- Table structure for table `adjacent_table` -- DROP TABLE IF EXISTS `adjacent_table`; CREATE TABLE IF NOT EXISTS `adjacent_table` ( `id` int(11) NOT NULL AUTO_INCREMENT, `father_id` int(11) DEFAULT NULL, `category` varchar(128) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=8 ; -- -- Dumping data for table `adjacent_table` -- INSERT INTO `adjacent_table` (`id`, `father_id`, `category`) VALUES (1, 0, 'Books'), (2, 0, 'CD''s'), (3, 0, 'Magazines'), (4, 1, 'Hard Cover'), (5, 1, 'Large Format'), (6, 3, 'Vintage'); -- -- Table structure for table `nested_table` -- DROP TABLE IF EXISTS `nested_table`; CREATE TABLE IF NOT EXISTS `nested_table` ( `lft` int(11) NOT NULL DEFAULT '0', `rgt` int(11) DEFAULT NULL, `id` int(11) DEFAULT NULL, `category` varchar(128) DEFAULT NULL, PRIMARY KEY (`lft`), UNIQUE KEY `id` (`id`), UNIQUE KEY `rgt` (`rgt`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; */ /** * @class tree_transformer * @author Paul Houle, Matthew Toledo * @created 2008-11-04 * @url http://gen5.info/q/2008/11/04/nested-sets-php-verb-objects-and-noun-objects/ */ class tree_transformer { private $i_count; private $a_link; public function __construct($a_link) { if(!is_array($a_link)) throw new Exception("First parameter should be an array.

Android map performance with > 800 overlays of KML data

- by span

I have some a shape file which I have converted to a KML file that I wish to read coordinates from and then draw paths between the coordinates on a MapView. With the help of this great post: How to draw a path on a map using kml file? I have been able to read the the KML into an ArrayList of "Placemarks". This great blog post then showed how to take a list of GeoPoints and draw a path: http://djsolid.net/blog/android---draw-a-path-array-of-points-in-mapview The example in the above post only draws one path between some points however and since I have many more paths than that I am running into some performance problems. I'm currently adding a new RouteOverlay for each of the separate paths. This results in me having over 800 overlays when they have all been added. This has a performance hit and I would love some input on what I can do to improve it. Here are some options I have considered: Try to add all the points to a List which then can be passed into a class that will extend Overlay. In that new class perhaps it would be possible to add and draw the paths in a single Overlay layer? I'm not sure on how to implement this though since the paths are not always intersecting and they have different start and end points. At the moment I'm adding each path which has several points to it's own list and then I add that to an Overlay. That results in over 700 overlays... Simplify the KML or SHP. Instead of having over 700 different paths, perhaps there is someway to merge them into perhaps 100 paths or less? Since alot of paths are intersected at some point it should be possible to modify the original SHP file so that it merges all intersections. Since I have never worked with these kinds of files before I have not been able to find a way to do this in GQIS. If someone knows how to do this I would love for some input on that. Here is a link to the group of shape files if you are interested: http://danielkvist.net/cprg_bef_cbana_polyline.shp http://danielkvist.net/cprg_bef_cbana_polyline.shx http://danielkvist.net/cprg_bef_cbana_polyline.dbf http://danielkvist.net/cprg_bef_cbana_polyline.prj Anyway, here is the code I'm using to add the Overlays.
