  • Displaying NON-ASCII Characters using HttpClient

    - by Abdullah Gheith
    So, i am using this code to get the whole HTML of a website. But i dont seem to get non-ascii characters with me. all i get is diamonds with question mark. characters like this: å, appears like this: ? I doubt its because of the charset, what could it then be? Log.e("HTML", "henter htmlen.."); String url = "http://beep.tv2.dk"; HttpClient client = new DefaultHttpClient(); client.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); client.getParams().setParameter(CoreProtocolPNames.HTTP_ELEMENT_CHARSET, "UTF-8"); HttpGet request = new HttpGet(url); HttpResponse response = client.execute(request); Header h = HeaderValueFormatter response.addHeader(header) String html = ""; InputStream in = response.getEntity().getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuilder str = new StringBuilder(); String line = null; while((line = reader.readLine()) != null) { str.append(line); } in.close(); //b = false; html = str.toString();

  • Implicit Type Conversions in Reflection

    - by bradhe
    So I've written a quick bit of code to help quickly convert between business objects and view models. Not to pimp my own blog, but you can find the details here if you're interested or need to know. One issue I've run in to is that I have a custom collection type, ProductCollection, and I need to turn that in to a string[] in on my model. Obviously, since there is no default implicit cast, I'm getting an exception in my contract converter. So, I thought I would write the next little bit of code and that should solve the problem: public static implicit operator string[](ProductCollection collection) { var list = new List<string>(); foreach (var product in collection) { if (product.Id == null) { list.Add(null); } else { list.Add(product.Id.ToString()); } } return list.ToArray(); } However, it still fails with the same cast exception. I'm wondering if it has something to do with being in reflection? If so, is there anything that I can do here?? I'm open to architectural solutions, too!

  • PHP static function self:: in joomla JFactory class explanation?

    - by Carbon6
    Hi I'm looking at the code of Joomla and trying to figure out what exactly happends in this function. index.php makes a call to function $app = JFactory::getApplication('site'); jfactory.php code public static function getApplication($id = null, $config = array(), $prefix='J') { if (!self::$application) { jimport('joomla.application.application'); self::$application = JApplication::getInstance($id, $config, $prefix); } return self::$application; } application.php code.. public static function getInstance($client, $config = array(), $prefix = 'J') { static $instances; if (!isset($instances)) { $instances = array(); } ....... more code ........ return $instances[$client]; } Now I cannot figure out in function getApplication why is self:$application used. self::$application = JApplication::getInstance($id, $config, $prefix); $application is always null, what is the purpose of using this approach. I tryied modifying it to $var = JApplication::getInstance($id, $config, $prefix); and returnig it but it doesn't work. I would be very glad if someone with more knowledge could explain what is happening here detailed as possible. Many thanks.

  • Linked List push()

    - by JKid314159
    The stack is initialized with a int MaxSize =3. Then I push one int onto the list. " Pushed:" is returned to the console. Program crashes here. I think my logic is flawed but unsure. Maybe an infinite loop or unmet condition? Thanks for your help. I'm trying to traverse the list to the last node in the second part of the full() method. I implemented this stack as array based so must implement this method full() as this method is inside of main class. while(!stacker.full()) { cout << "Enter number = "; cin >> intIn; stacker.push(intIn); cout << "Pushed: " << intIn << endl; }//while Call to LinkListStack.cpp to class LinkList full(). int LinkList::full() { if(head == NULL) { top = 0; } else { LinkNode * tmp1; LinkNode * tmp2; tmp1 = head; while(top != MaxSize) { if(tmp1->next != NULL){ tmp2 = tmp1->next; tmp1 = tmp2; ++top; }//if }//while }//else return (top + 1 == MaxSize); }

    I have the following entities Student @Entity public class Student implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; //getter and setter for id } Teacher @Entity public class Teacher implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; //getter and setter for id } Task @Entity public class Task implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @ManyToOne(optional = false) @JoinTable(name = "student_task", inverseJoinColumns = { @JoinColumn(name = "student_id") }) private Student author; @ManyToOne(optional = false) @JoinTable(name = "student_task", inverseJoinColumns = { @JoinColumn(name = "teacher_id") }) private Teacher curator; //getters and setters } Consider that author and curator are already stored in DB and both are in the attached state. I'm trying to persist my Task: Task task = new Task(); task.setAuthor(author); task.setCurator(curator); entityManager.persist(task); Hibernate executes the following SQL: insert into student_task (teacher_id, id) values (?, ?) which, of course, leads to null value in column "student_id" violates not-null constraint Can anyone explain this issue and possible ways to resolve it?

  • Dynamic Auto updating (to UI, Grid) binding list in C# Winform?

    - by Dhana
    I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class/interface. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) Here the list is a Sync list which will auto update the UI, in this case datagridview. Every thing works fine now, but now i would like to have the List should have an dynamic object, that is the object will have by default two static property (ID, Name), and at run time user will select remaining properties. These should be bind to the data grid. Any update on the list should be auto reflected in the grid. I am aware that, we can use dynamic objects, but i would like to know , how to approach for solution, datagridview.DataSource = myData; // myData is AutoUpdateList<IPersonInfo> Now IPersonInfo is the type of object, need to add dynamic properties for this type at runtime. public class AutoUpdateList<T> : System.ComponentModel.BindingList<T> { private System.ComponentModel.ISynchronizeInvoke _SyncObject; private System.Action<System.ComponentModel.ListChangedEventArgs> _FireEventAction; public AutoUpdateList() : this(null) { } public AutoUpdateList(System.ComponentModel.ISynchronizeInvoke syncObject) { _SyncObject = syncObject; _FireEventAction = FireEvent; } protected override void OnListChanged(System.ComponentModel.ListChangedEventArgs args) { try { if (_SyncObject == null) { FireEvent(args); } else { _SyncObject.Invoke(_FireEventAction, new object[] { args }); } } catch (Exception) { // TODO: Log Here } } private void FireEvent(System.ComponentModel.ListChangedEventArgs args) { base.OnListChanged(args); } } Could you help out on this?

  • Optimizing an embedded SELECT query in mySQL

    - by Crazy Serb
    Ok, here's a query that I am running right now on a table that has 45,000 records and is 65MB in size... and is just about to get bigger and bigger (so I gotta think of the future performance as well here): SELECT count(payment_id) as signup_count, sum(amount) as signup_amount FROM payments p WHERE tm_completed BETWEEN '2009-05-01' AND '2009-05-30' AND completed > 0 AND tm_completed IS NOT NULL AND member_id NOT IN (SELECT p2.member_id FROM payments p2 WHERE p2.completed=1 AND p2.tm_completed < '2009-05-01' AND p2.tm_completed IS NOT NULL GROUP BY p2.member_id) And as you might or might not imagine - it chokes the mysql server to a standstill... What it does is - it simply pulls the number of new users who signed up, have at least one "completed" payment, tm_completed is not empty (as it is only populated for completed payments), and (the embedded Select) that member has never had a "completed" payment before - meaning he's a new member (just because the system does rebills and whatnot, and this is the only way to sort of differentiate between an existing member who just got rebilled and a new member who got billed for the first time). Now, is there any possible way to optimize this query to use less resources or something, and to stop taking my mysql resources down on their knees...? Am I missing any info to clarify this any further? Let me know... EDIT: Here are the indexes already on that table: PRIMARY PRIMARY 46757 payment_id member_id INDEX 23378 member_id payer_id INDEX 11689 payer_id coupon_id INDEX 1 coupon_id tm_added INDEX 46757 tm_added, product_id tm_completed INDEX 46757 tm_completed, product_id

  • How can I simply change a class variable from another class in ObjectiveC?

    - by Daniel
    I simply want to change a variable of an object from another class. I can compile without a problem, but my variable always is set to 'null'. I used the following code: Object.h: @interface Object : NSObject { //... NSString *color; //... } @property(nonatomic, retain) NSString* color; + (id)Object; - (void)setColor:(NSString*)col; - (NSString*)getColor; @end Object.m: +(id)Object{ return [[[Object alloc] init] autorelease]; } - (void)setColor:(NSString*)col { self.color = col; } - (NSString*)getColor { return self.color; } MyViewController.h #import "Object.h" @interface ClassesTestViewController : UIViewController { Object *myObject; UILabel *label1; } @property UILabel *label1; @property (assign) Object *myObject; @end MyViewController.m: #import "Object.h" @implementation MyViewController @synthesize myObject; - (void)viewDidLoad { [myObject setColor:@"red"]; NSLog(@"Color = %@", [myObject getColor]); [super viewDidLoad]; } The NSLog message is always Color = (null) I tried many different ways to solve this problem, but no success. Any help would be appreciated.

  • Clicking inside a polygon in Google Maps

    - by amarsh-anand
    The included JavaScript snippet is supposed to do the following: As the user clicks on the map, initialize headMarker and draw a circle (polygon) around it As the user clicks inside the circle, initialize tailMarker and draw the path between these two markers 1 is happening as expected. But as the user clicks inside the circle, in the function(overlay,point), overlay is non-null while point is null. Because of this, the code fails to initialize tailMarker. Can someone tell me a way out. GEvent.addListener(map, "click", function(overlay,point) { if (isCreateHeadPoint) { // add the head marker headMarker = new GMarker(point,{icon:redIcon,title:'0'}); map.addOverlay(headMarker); isCreateHeadPoint = false; // draw the circle drawMapCircle(point.lat(),point.lng(),1,'#cc0000',2,0.8,'#0',0.1); } else { // add the tail marker tailMarker = new GMarker(point,{icon:greenIcon,title:''}); map.addOverlay(tailMarker); isCreateHeadPoint = true; // load thes path from head to tail direction.load("from:" + headMarker.getPoint().lat()+ ", " + headMarker.getPoint().lng()+ " " + "to:" + tailMarker.getPoint().lat() + "," + tailMarker.getPoint().lng(), {getPolyline:true}); } });

  • Help on using mod_rewrite to serve I18N static site

    - by Guandalino
    My static site www.example.com is translated in different languages and files are organized in this hierarchy: / /de index.html seite-1.html /en index.html page-1.html /it index.html pagina-1.html The root contains no files, just one subdirectory for each language the site is translated in, while subdirectories contain pages translated (both content and file name are) in the language corresponding to subdirectory name, de, en, it, etc. The question is: how to configure mod_rewrite so that when a client visits www.example.com it is taken to the correct version of the site, falling back to english version if the required locale is not supported (i.e. Accept-Language header doesn't exist or specifies a language for which the site is not available, e.g. fr)? Thanks for any pointer, I'm here to provide further details or feedback! Best regards

Is there something wrong in my code? public void SendAllNewsletters(List<string> recipients) { string mailText = "My Tex"; foreach(string recipient in recipients) { //if this loop takes 10min then the first call to //SendCompletedCallback is after 10min SendNewsletter(mailText,recipient); } } public bool SendNewsletter(string mailText , string emailaddress) { SmtpClient sc = new SmtpClient(_smtpServer, _smtpPort); System.Net.NetworkCredential SMTPUserInfo = new System.Net.NetworkCredential(_smtpuser, _smtppassword); sc.Credentials = SMTPUserInfo; sc.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailMessage mm = null; mm = new MailMessage(mailText, emailaddress); mm.IsBodyHtml = true; mm.Priority = MailPriority.Normal; mm.Subject = "Something"; mm.Body = "Something"; mm.SubjectEncoding = Encoding.UTF8; mm.BodyEncoding = Encoding.UTF8; //Mail string userState = emailaddress; sc.SendAsync(mm, userState); return true; } public void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string)e.UserState; if (e.Error != null) { _news.SetNewsletterEmailsisSent(e.UserState.ToString(), _newslettername, false, e.Error.Message); } else { _news.SetNewsletterEmailsisSent(e.UserState.ToString(), _newslettername, true, string.Empty); } }

  • Explorer forgetting how to cut and paste files

    - by raimesh
    My Windows XP (SP3) machine (at work) occasionally "forgets" how to cut-and-paste files in Explorer - if I cut or copy a file then go to paste it elsewhere, the "paste" and "paste shortcut" menu items are greyed out. The keyboard shortcuts (Ctrl+X/Ctrl+C,Ctrl+V) don't work either, and neither does Drag-and-Drop - clicking and dragging a file/folder doesn't change the pointer and letting go doesn't drop the item anywhere. Restarting the explorer.exe process usually fixes the problem, but sometimes I need to do a full reboot. Note: this may be related to the following existing question, although that's Vista and it sounds like the asker has more permanent problems than I do: http://superuser.com/questions/27045/copy-paste-in-vista-explorer-broken-not-ms-vpc So, any idea what might be causing the problem and how to avoid it?

  • Create new or update existing entity at one go with JPA

    - by Alex R
    A have a JPA entity that has timestamp field and is distinguished by a complex identifier field. What I need is to update timestamp in an entity that has already been stored, otherwise create and store new entity with the current timestamp. As it turns out the task is not as simple as it seems from the first sight. The problem is that in concurrent environment I get nasty "Unique index or primary key violation" exception. Here's my code: // Load existing entity, if any. Entity e = entityManager.find(Entity.class, id); if (e == null) { // Could not find entity with the specified id in the database, so create new one. e = entityManager.merge(new Entity(id)); } // Set current time... e.setTimestamp(new Date()); // ...and finally save entity. entityManager.flush(); Please note that in this example entity identifier is not generated on insert, it is known in advance. When two or more of threads run this block of code in parallel, they may simultaneously get null from entityManager.find(Entity.class, id) method call, so they will attempt to save two or more entities at the same time, with the same identifier resulting in error. I think that there are few solutions to the problem. Sure I could synchronize this code block with a global lock to prevent concurrent access to the database, but would it be the most efficient way? Some databases support very handy MERGE statement that updates existing or creates new row if none exists. But I doubt that OpenJPA (JPA implementation of my choice) supports it. Event if JPA does not support SQL MERGE, I can always fall back to plain old JDBC and do whatever I want with the database. But I don't want to leave comfortable API and mess with hairy JDBC+SQL combination. There is a magic trick to fix it using standard JPA API only, but I don't know it yet. Please help.

  • Why is the compiler caching my "random" and NULLED variables?

    - by alex gray
    I am confounded by the fact that even using different programs (on the same machine) to run /compile, and after nilling the vaues (before and after) the function.. that NO MATTER WHAT.. I'll keep getting the SAME "random" numbers… each and every time I run it. I swear this is NOT how it's supposed to work.. I'm going to illustrate as simply as is possible… #import <Foundation/Foundation.h> int main(int argc, char *argv[]) { int rPrimitive = 0; rPrimitive = 1 + rand() % 50; NSNumber *rObject = nil; rObject = [NSNumber numberWithInt:rand() % 10]; NSLog(@"%i %@", rPrimitive, rObject); rPrimitive = 0; rObject = nil; NSLog(@"%i %@", rPrimitive, rObject); return 0; } Run it in TextMate: i686-apple-darwin11-llvm-gcc-4.2 8 9 0 (null) Run it in CodeRunner: i686-apple-darwin11-llvm-gcc-4.2 8 9 0 (null) Run it a million times, if you'd like. You can gues what it will always be. Why does this happen? Why oh why is this "how it is"?

  • Javascript Cookie Function not working for Domain

    - by danit
    Here are the functions Im using: Set Cookie: function set_cookie ( name, value, exp_y, exp_m, exp_d, path, domain, secure ) { var cookie_string = name + "=" + escape ( value ); if ( exp_y ) { var expires = new Date ( exp_y, exp_m, exp_d ); cookie_string += "; expires=" + expires.toGMTString(); } if ( path ) cookie_string += "; path=" + escape ( path ); if ( domain ) cookie_string += "; domain=" + escape ( domain ); if ( secure ) cookie_string += "; secure"; document.cookie = cookie_string; } Read Cookie: function get_cookie ( cookie_name ) { var results = document.cookie.match ( '(^|;) ?' + cookie_name + '=([^;]*)(;|$)' ); if ( results ) return ( unescape ( results[2] ) ); else return null; } Delete Cookie: function delete_cookie ( cookie_name ) { var cookie_date = new Date ( ); // current date & time cookie_date.setTime ( cookie_date.getTime() - 1 ); document.cookie = cookie_name += "=; expires=" + cookie_date.toGMTString(); } The Jquery I use to construct the cookie: if(get_cookie('visible')== 'no') { $("#wrapper").hide(); $(".help").hide(); $("#slid .show").show(); $("#slid .hide").hide(); } else { $("#slid .show").hide(); $("#slid .hide").show(); } $("#slider").click(function() { if(get_cookie('visible')== null) { set_cookie('visible','no', 2020, 01,01, '/', 'domain.com'); } else { delete_cookie('visible'); } $(".help").slideToggle(); $("#wrapper").animate({ opacity: 1.0 },200).slideToggle(200, function() { $("#slid img").toggle(); }); }); Im trying to set the cookie for all pages that exist under domain.com with the path '/'. However using these functions and jQuery it doesn't appear to be working, any anyone give me an idea of where im going wrong?

  • Why is this linq extension method hit the database twice?

    - by Pure.Krome
    Hi folks, I have an extension method called ToListIfNotNullOrEmpty(), which is hitting the DB twice, instead of once. The first time it returns one result, the second time it returns all the correct results. I'm pretty sure the first time it hits the database, is when the .Any() method is getting called. here's the code. public static IList<T> ToListIfNotNullOrEmpty<T>(this IEnumerable<T> value) { if (value.IsNullOrEmpty()) { return null; } if (value is IList<T>) { return (value as IList<T>); } return new List<T>(value); } public static bool IsNullOrEmpty<T>(this IEnumerable<T> value) { if (value != null) { return !value.Any(); } return true; } I'm hoping to refactor it so that, before the .Any() method is called, it actually enumerates through the entire list. If i do the following, only one DB call is made, because the list is already enumerated. var pewPew = (from x in whatever select x) .ToList() // This enumerates. .ToListIsNotNullOrEmpty(); // This checks the enumerated result. I sorta don't really want to call ToList() then my extension method. Any ideas, folks?

  • How can I improve the performance of LinqToSql queries that use EntitySet properties?

    - by DanM
    I'm using LinqToSql to query a small, simple SQL Server CE database. I've noticed that any operations involving sub-properties are disappointingly slow. For example, if I have a Customer table that is referenced by an Order table, LinqToSql will automatically create an EntitySet<Order> property. This is a nice convenience, allowing me to do things like Customer.Order.Where(o => o.ProductName = "Stopwatch"), but for some reason, SQL Server CE hangs up pretty bad when I try to do stuff like this. One of my queries, which isn't really that complicated takes 3-4 seconds to complete. I can get the speed up to acceptable, even fast, if I just grab the two tables individually and convert them to List<Customer> and List<Order>, then join then manually with my own query, but this is throwing out a lot of what makes LinqToSql so appealing. So, I'm wondering if I can somehow get the whole database into RAM and just query that way, then occasionally save it. Is this possible? How? If not, is there anything else I can do to boost the performance besides resorting to doing all the joins manually? Note: My database in its initial state is about 250K and I don't expect it to grow to more than 1-2Mb. So, loading the data into RAM certainly wouldn't be a problem from a memory point of view. Update Here are the table definitions for the example I used in my question: create table Order ( Id int identity(1, 1) primary key, ProductName ntext null ) create table Customer ( Id int identity(1, 1) primary key, OrderId int null references Order (Id) )

  • delete vs execSQL commands android

    - by erik
    so i have a databas, SQLiteDatabase db I am writing a couple private methods in my manager class that will be called by a public method: public void updateData (MakeabilityModel newData){ SQLiteDatabase db = this.getWritableDatabase(); db.beginTransaction(); try { reWriteSVTable(db, list); db.setTransactionSuccessful(); } catch (Exception e){ //TODO through rollback message? e.printStackTrace(); } finally { db.endTransaction(); } } //Private Methods private void clearTable(SQLiteDatabase db, String table){ db.delete(table, null, null); } private void reWriteSVTable(SQLiteDatabase db, List<MakeabilityLens> lenses){ clearTable(db, singleVision); ContentValues cv; for(int i=0; i<lenses.size(); i++){ cv = new ContentValues(); cv.put(colScreenID, hsID); cv.put(colIconID, id); cv.put(colRank, hsTotal); db.insert(isLookUp, colID, cv); } } My question is this.. i want to be able to throw sql exceptions back to the public method so that if there is an exception, it will kill the transaction and rollback ALL data.. it appears that using delete() and insert() methods are cleaner than execSQL() but don't throw sqlExceptions. execSQL() on the other hand does? do i need to uses execSQL and how do i insure that hsould it throws an exception in any of the private methods that it will catch it and roll it back in the private method

  • HTTP Compression problems on IIS7

    - by Jonathan Wood
    I've spent quite a bit of time on this but seem to be going nowhere. I have a large page that I really want to speed up. The obvious place to start seems to be HTTP compression, but I just can't seem to get it to work for me. After considerable searching, I've tried several variations of the code below. It kind of works, but after refreshing the browser, the results seem to fall apart. They were turning to garbage when the page used caching. If I turn off caching, then the page seems right but I lose my CSS formatting (stored in a separate file) and get an error that an included JS file contains invalid characters. Most of the resources I've found on the Web were either very old or focused on accessing IIS directly. My page is running on a shared hosting account and I do not have direct access to IIS7, which it's running on. protected void Application_BeginRequest(object sender, EventArgs e) { // Implement HTTP compression if (Request["HTTP_X_MICROSOFTAJAX"] == null) // Avoid compressing AJAX calls { // Retrieve accepted encodings string encodings = Request.Headers.Get("Accept-Encoding"); if (encodings != null) { // Verify support for or gzip (deflate takes preference) encodings = encodings.ToLower(); if (encodings.Contains("gzip") || encodings == "*") { Response.Filter = new GZipStream(Response.Filter, CompressionMode.Compress); Response.AppendHeader("Content-Encoding", "gzip"); Response.Cache.VaryByHeaders["Accept-encoding"] = true; } else if (encodings.Contains("deflate")) { Response.Filter = new DeflateStream(Response.Filter, CompressionMode.Compress); Response.AppendHeader("Content-Encoding", "deflate"); Response.Cache.VaryByHeaders["Accept-encoding"] = true; } } } } Is anyone having better success with this?
