  • How to manage a One-To-One and a One-To-Many of same type as unidirectional mapping?

    - by user1652438
    I'm trying to implement a model for private messages between two or more users. That means I've got two Entities: User PrivateMessage The User model shouldn't be edited, so I'm trying to set up an unidirectional relationship: @Entity (name = "User") @Table (name = "user") public class User implements Serializable { @Id String username; String password; // something like this ... } The PrivateMessage Model addresses multiple receivers and has exactly one sender. So I need something like this: @Entity (name = "PrivateMessage") @Table (name = "privateMessage") @XmlRootElement @XmlType (propOrder = {"id", "sender", "receivers", "title", "text", "date", "read"}) public class PrivateMessage implements Serializable { private static final long serialVersionUID = -9126766942868177246L; @Id @GeneratedValue private Long id; @NotNull private String title; @NotNull private String text; @NotNull @Temporal(TemporalType.TIMESTAMP) private Date date; @NotNull private boolean read; @NotNull @ElementCollection(fetch = FetchType.EAGER, targetClass = User.class) private Set<User> receivers; @NotNull @OneToOne private User sender; // and so on } The according 'privateMessage' table won't be generated and just the relationship between the PM and the many receivers is satisfied. I'm confused about this. Everytime I try to set a 'mappedBy' attribute, my IDE marks it as an error. It seems to be a problem that the User-entity isn't aware of the private message which maps it. What am I doing wrong here? I've solved some situation similar to this one, but none of those solutions will work here. Thanks in advance!

  • Linq to SQL case sensitivity causing problems

    - by Roger Lipscombe
    I've seen this question, but that's asking for case-insensitive comparisons when the database is case-sensitive. I'm having a problem with the exact opposite. I'm using SQL Server 2005, my database collation is set to Latin1_General_CI_AS. I've got a table, "User", like this: CREATE TABLE [dbo].[User] ( [Id] [int] IDENTITY(1,1) NOT NULL, [Name] [nvarchar](max) NOT NULL, CONSTRAINT [PK_Example] PRIMARY KEY CLUSTERED ( [Id] ASC ) ) And I'm using the following code to populate it: string[] names = new[] { "Bob", "bob", "BoB" }; using (MyDataContext dataContext = new AppCompatDataContext()) { foreach (var name in names) { string s = name; if (dataContext.Users.SingleOrDefault(u => u.Name == s) == null) dataContext.Users.InsertOnSubmit(new User { Name = name }); } dataContext.SubmitChanges(); } When I run this the first time, I end up with "Bob", "bob" and "BoB" in the table. When I run it again, I get an InvalidOperationException: "Sequence contains more than one element", because the query against the database returns all 3 rows, and... SELECT * FROM [User] WHERE Name = 'bob' ... is case-insensitive. That is: when I'm inserting rows, Linq to SQL appears to use C# case-sensitive comparisons. When I query later, Linq to SQL uses SQL Server case-insensitive comparisons. I'd like the initial insert to use case-insensitive comparisons, but when I change the code as follows... if (dataContext.Users.SingleOrDefault(u => u.Name.Equals(s, StringComparison.InvariantCultureIgnoreCase) ) == null) ... I get a NotSupportedException: "Method 'Boolean Equals(System.String, System.StringComparison)' has no supported translation to SQL." Question: how do I get the initial insert to be case-insensitive or, more precisely, match the collation of the column in the database? Update: This doesn't appear to be my problem. My problem appears to be that SingleOrDefault doesn't actually look at the pending inserts at all.

  • MINA: Performing synchronous write requests / read responses

    - by Matt Huggins
    I'm attempting to perform a synchronous write/read in a demux-based client application with MINA 2.0 RC1, but it seems to get stuck. Here is my code: public boolean login(final String username, final String password) { // block inbound messages session.getConfig().setUseReadOperation(true); // send the login request final LoginRequest loginRequest = new LoginRequest(username, password); final WriteFuture writeFuture = session.write(loginRequest); writeFuture.awaitUninterruptibly(); if (writeFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // retrieve the login response final ReadFuture readFuture = session.read(); readFuture.awaitUninterruptibly(); if (readFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // stop blocking inbound messages session.getConfig().setUseReadOperation(false); // determine if the login info provided was valid final LoginResponse loginResponse = (LoginResponse)readFuture.getMessage(); return loginResponse.getSuccess(); } I can see on the server side that the LoginRequest object is retrieved, and a LoginResponse message is sent. On the client side, the DemuxingProtocolCodecFactory receives the response, but after throwing in some logging, I can see that the client gets stuck on the call to readFuture.awaitUninterruptibly(). I can't for the life of me figure out why it is stuck here based upon my own code. I properly set the read operation to true on the session config, meaning that messages should be blocked. However, it seems as if the message no longer exists by time I try to read response messages synchronously. Any clues as to why this won't work for me?

  • Publishing my Website to my Local Disk Causes Exceptions to show Paths including my Local Disk

    - by coffeeaddict
    I've published my website many times. But didn't think about this though until I came across this issue. So I decided to publish my WAP project to a local folder on my C drive first. Then used FTP to upload it to my shared host on discountasp.net. I noticed during runtime that the stack trace was referencing that local folder still and erroring out. Anyone know what config settings are affected when publishing? Obviously something is still pointing to my local C drive and I've searched my entire solution and don't see why. Here's the runtime error I get when my code tries to run in discountasp.net's web server Cannot write into the public directory - check permissions Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: ScrewTurn.Wiki.PluginFramework.InvalidConfigurationException: Cannot write into the public directory - check permissions Source Error: An unhandled exception was generated during the execution of the current web request.

  • Actionscript 3.0 - drag and throw with easing

    - by Joe Hamilton
    I'm creating a map in flash and I would like to have a smooth movement similar to this: http://www.conceptm.nl/ I have made a start but I'm having trouble taking it to the next stage. My code currently throws the movieclip after the mouse is release but there is no easing while the mouse button is down. Any tips on how I would achieve this? Here is my current code: // Vars var previousPostionX:Number; var previousPostionY:Number; var throwSpeedX:Number; var throwSpeedY:Number; var isItDown:Boolean; // Event Listeners addEventListener(MouseEvent.MOUSE_DOWN, clicked); addEventListener(MouseEvent.MOUSE_UP, released); // Event Handlers function clicked(theEvent:Event) { isItDown =true; addEventListener(Event.ENTER_FRAME, updateView); } function released(theEvent:Event) { isItDown =false; } function updateView(theEvent:Event) { if (isItDown==true){ throwSpeedX = mouseX - previousPostionX; throwSpeedY = mouseY - previousPostionY; mcTestMovieClip.x = mouseX; mcTestMovieClip.y = mouseY; } else{ mcTestMovieClip.x += throwSpeedX; mcTestMovieClip.y += throwSpeedY; throwSpeedX *=0.9; throwSpeedY *=0.9; } previousPostionX= mcTestMovieClip.x; previousPostionY= mcTestMovieClip.y; }

  • Mysql german accents not-sensitive search in full-text searches

    - by lukaszsadowski
    Let`s have a example hotels table: CREATE TABLE `hotels` ( `HotelNo` varchar(4) character set latin1 NOT NULL default '0000', `Hotel` varchar(80) character set latin1 NOT NULL default '', `City` varchar(100) character set latin1 default NULL, `CityFR` varchar(100) character set latin1 default NULL, `Region` varchar(50) character set latin1 default NULL, `RegionFR` varchar(100) character set latin1 default NULL, `Country` varchar(50) character set latin1 default NULL, `CountryFR` varchar(50) character set latin1 default NULL, `HotelText` text character set latin1, `HotelTextFR` text character set latin1, `tagsforsearch` text character set latin1, `tagsforsearchFR` text character set latin1, PRIMARY KEY (`HotelNo`), FULLTEXT KEY `fulltextHotelSearch` (`HotelNo`,`Hotel`,`City`,`CityFR`,`Region`,`RegionFR`,`Country`,`CountryFR`,`HotelText`,`HotelTextFR`,`tagsforsearch`,`tagsforsearchFR`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_german1_ci; In this table for example we have only one hotel with Region name = "Graubünden" (please note umlaut ü character) And now I want to achieve same search match for phrases: 'graubunden' and 'graubünden' This is simple with use of MySql built in collations in regular searches as follows: SELECT * FROM `hotels` WHERE `Region` LIKE CONVERT(_utf8 '%graubunden%' USING latin1) COLLATE latin1_german1_ci This works fine for 'graubunden' and 'graubünden' and as a result I receive proper result, but problem is when we make MySQL full text search Whats wrong with this SQL statement?: SELECT * FROM hotels WHERE MATCH (`HotelNo`,`Hotel`,`Address`,`City`,`CityFR`,`Region`,`RegionFR`,`Country`,`CountryFR`, `HotelText`, `HotelTextFR`, `tagsforsearch`, `tagsforsearchFR`) AGAINST( CONVERT('+graubunden' USING latin1) COLLATE latin1_german1_ci IN BOOLEAN MODE) ORDER BY Country ASC, Region ASC, City ASC This doesn`t return any result. Any ideas where the dog is buried ?

  • Windows Service Conundrum

    - by Paul Johnson
    All, I have a Custom object which I have written using VB.NET (.net 2.0). The object instantiates its own threading.timer object and carries out a number of background process including periodic interrogation of an oracle database and delivery of emails via smtp according to data detected in the database. The following is the code implemented in the windows service class Public Class IncidentManagerService 'Fakes Private _fakeRepoFactory As IRepoFactory Private _incidentRepo As FakeIncidentRepo Private _incidentDefinitionRepo As FakeIncidentDefinitionRepo Private _incManager As IncidentManager.Session 'Real Private _started As Boolean = False Private _repoFactory As New NHibernateRepoFactory Private _psalertsEventRepo As IPsalertsEventRepo = _repoFactory.GetPsalertsEventRepo() Protected Overrides Sub OnStart(ByVal args() As String) ' Add code here to start your service. This method should set things ' in motion so your service can do its work. If Not _started Then Startup() _started = True End If End Sub Protected Overrides Sub OnStop() 'Tear down class variables in order to ensure the service stops cleanly _incManager.Dispose() _incidentDefinitionRepo = Nothing _incidentRepo = Nothing _fakeRepoFactory = Nothing _repoFactory = Nothing End Sub Private Sub Startup() Dim incidents As IList(Of Incident) = Nothing Dim incidentFactory As New IncidentFactory incidents = IncidentFactory.GetTwoFakeIncidents _repoFactory = New NHibernateRepoFactory _fakeRepoFactory = New FakeRepoFactory(incidents) _incidentRepo = _fakeRepoFactory.GetIncidentRepo _incidentDefinitionRepo = _fakeRepoFactory.GetIncidentDefinitionRepo 'Start an incident manager session _incManager = New IncidentManager.Session(_incidentRepo, _incidentDefinitionRepo, _psalertsEventRepo) _incManager.Start() End Sub End Class After a little bit of experimentation I arrived at the above code in the OnStart method. All functionality passed testing when deployed from VS2005 on my development PC, however when deployed on a true target machine, the service would not start and responds with the following message: "The service on local computer started and then stopped..." Am I going about this the correct way? If not how can I best implement my incident manager within the confines of the Windows Service class. It seems pointless to implement a timer for the incidentmanager because this already implements its own timer... Any assistance much appreciated. Kind Regards Paul J.

  • How to make Stack.Pop threadsafe

    - by user260197
    I am using the BlockingQueue code posted in this question, but realized I needed to use a Stack instead of a Queue given how my program runs. I converted it to use a Stack and renamed the class as needed. For performance I removed locking in Push, since my producer code is single threaded. My problem is how can thread working on the (now) thread safe Stack know when it is empty. Even if I add another thread safe wrapper around Count that locks on the underlying collection like Push and Pop do, I still run into the race condition that access Count and then Pop are not atomic. Possible solutions as I see them (which is preferred and am I missing any that would work better?): Consumer threads catch the InvalidOperationException thrown by Pop(). Pop() return a nullptr when _stack-Count == 0, however C++-CLI does not have the default() operator ala C#. Pop() returns a boolean and uses an output parameter to return the popped element. Here is the code I am using right now: generic <typename T> public ref class ThreadSafeStack { public: ThreadSafeStack() { _stack = gcnew Collections::Generic::Stack<T>(); } public: void Push(T element) { _stack->Push(element); } T Pop(void) { System::Threading::Monitor::Enter(_stack); try { return _stack->Pop(); } finally { System::Threading::Monitor::Exit(_stack); } } public: property int Count { int get(void) { System::Threading::Monitor::Enter(_stack); try { return _stack->Count; } finally { System::Threading::Monitor::Exit(_stack); } } } private: Collections::Generic::Stack<T> ^_stack; };

  • HttpModule.Init - safely add HttpApplication.BeginRequest handler in IIS7 integrated mode

    - by Paul Smith
    My question is similar but not identical to: http://stackoverflow.com/questions/1123741/why-cant-my-host-softsyshosting-com-support-beginrequest-and-endrequest-event (I've also read the mvolo blog referenced therein) The goal is to successfully hook HttpApplication.BeginRequest in the IHttpModule.Init event (or anywhere internal to the module), using a normal HttpModule integrated via the system.webServer config, i.e. one that doesn't: invade Global.asax or override the HttpApplication (the module is intended to be self-contained & reusable, so e.g. I have a config like this): <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules> <remove name="TheHttpModule" /> <add name="TheHttpModule" type="Company.HttpModules.TheHttpModule" preCondition="managedHandler" /> So far, any strategy I've tried to attach a listener to HttpApplication.BeginRequest results in one of two things, symptom 1 is that BeginRequest never fires, or symptom 2 is that the following exception gets thrown on all managed requests, and I cannot catch & handle it from user code: Stack Trace: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616 Commenting out app.BeginRequest += new EventHandler(this.OnBeginRequest) in Init stops the exception of course. Init does not reference the Context or Request objects at all. I have tried: Removed all references to HttpContext.Current anywhere in the project (still symptom 1) Tested removing all code from the body of my OnBeginRequest method, to ensure the problem wasn't internal to the method (= exception) Sniffing the stack trace and only calling app.BeginRequest+=... when if the stack isn't started by InitializeApplication (= BeginRequest not firing) Only calling app.BeginRequest+= on the second pass through Init (= BeginRequest not firing) Anyone know of a good approach? Is there some indirect strategy for hooking Application_Start within the module (seems unlikely)? Another event which a) one can hook from a module's constructor or Init method, and b) which is subsequently a safe place to attach BeginRequest event handlers? Thanks much

  • Infinite loop in regex in java

    - by carpediem
    Hello, My purpose is to match this kind of different urls: url.com my.url.com my.extended.url.com a.super.extended.url.com and so on... So, I decided to build the regex to have a letter or a number at start and end of the url, and to have a infinite number of "subdomains" with alphanumeric characters and a dot. For example, in "my.extended.url.com", "m" from "my" is the first class of the regex, "m" from "com" is the last class of the regex, and "y.", "extended." and "url." are the second class of the regex. Using the pattern and subject in the code below, I want the find method to return me a false because this url must not match, but it uses 100% of CPU and seems to stay in an infinite loop. String subject = "www.association-belgo-palestinienne-be"; Pattern pattern = Pattern.compile("^[A-Za-z0-9]\\.?([A-Za-z0-9_-]+\\.?)*[A-Za-z0-9]\\.[A-Za-z]{2,6}"); Matcher m = pattern.matcher(subject); System.out.println(" Start"); boolean hasFind = m.find(); System.out.println(" Finish : " + hasFind); Which only prints: Start I can't reproduce the problem using regex testers. Is it normal ? Is the problem coming from my regex ? Could it be due to my Java version (1.6.0_22-b04 / JVM 64 bit 17.1-b03) ? Thanks in advance for helping.

  • Smack API giving error while logging into Tigase Server setup locally

    - by Ameya Phadke
    Hi, I am currently developing android XMPP client to communicate with the Tigase server setup locally.Before starting development on Android I am writing a simple java code on PC to test connectivity with XMPP server.My XMPP domain is my pc name "mwbn43-1" and administrator username and passwords are admin and tigase respectively. Following is the snippet of the code I am using class Test { public static void main(String args[])throws Exception { System.setProperty("smack.debugEnabled", "true"); XMPPConnection.DEBUG_ENABLED = true; ConnectionConfiguration config = new ConnectionConfiguration("mwbn43-1", 5222); config.setCompressionEnabled(true); config.setSASLAuthenticationEnabled(true); XMPPConnection con = new XMPPConnection(config); // Connect to the server con.connect(); con.login("admin", "tigase"); Chat chat = con.getChatManager().createChat("aaphadke@mwbn43-1", new MessageListener() { public void processMessage(Chat chat, Message message) { // Print out any messages we get back to standard out. System.out.println("Received message: " + message); } }); try { chat.sendMessage("Hi!"); } catch (XMPPException e) { System.out.println("Error Delivering block"); } String host = con.getHost(); String user = con.getUser(); String id = con.getConnectionID(); int port = con.getPort(); boolean i = false; i = con.isConnected(); if (i) System.out.println("Connected to host " + host + " via port " + port + " connection id is " + id); System.out.println("User is " + user); con.disconnect(); } } When I run this code I get following error Exception in thread "main" Resource binding not offered by server: at org.jivesoftware.smack.SASLAuthentication.bindResourceAndEstablishSession(SASLAuthenticatio n.java:416) at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:331) at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:395) at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:349) at Test.main(Test.java:26) I found this articles on the same problem but no concrete solution here Could anyone please tell me the solution for this problem.I checked the XMPPConnection.java file in the Smack API and it looks the same as given in the link solution. Thanks, Ameya

  • Autodetect Presence of CSV Headers in a File

    - by banzaimonkey
    Short question: How do I automatically detect whether a CSV file has headers in the first row? Details: I've written a small CSV parsing engine that places the data into an object that I can access as (approximately) an in-memory database. The original code was written to parse third-party CSV with a predictable format, but I'd like to be able to use this code more generally. I'm trying to figure out a reliable way to automatically detect the presence of CSV headers, so the script can decide whether to use the first row of the CSV file as keys / column names or start parsing data immediately. Since all I need is a boolean test, I could easily specify an argument after inspecting the CSV file myself, but I'd rather not have to (go go automation). I imagine I'd have to parse the first 3 to ? rows of the CSV file and look for a pattern of some sort to compare against the headers. I'm having nightmares of three particularly bad cases in which: The headers include numeric data for some reason The first few rows (or large portions of the CSV) are null There headers and data look too similar to tell them apart If I can get a "best guess" and have the parser fail with an error or spit out a warning if it can't decide, that's OK. If this is something that's going to be tremendously expensive in terms of time or computation (and take more time than it's supposed to save me) I'll happily scrap the idea and go back to working on "important things". I'm working with PHP, but this strikes me as more of an algorithmic / computational question than something that's implementation-specific. If there's a simple algorithm I can use, great. If you can point me to some relevant theory / discussion, that'd be great, too. If there's a giant library that does natural language processing or 300 different kinds of parsing, I'm not interested.

  • Parsing a string, Grammar file.

    - by defn
    How would I separate the below string into its parts. What I need to separate is each < Word including the angle brackets from the rest of the string. So in the below case I would end up with several strings 1. "I have to break up with you because " 2. "< reason " (without the spaces) 3. " . But Let's still " 4. "< disclaimer " 5. " ." I have to break up with you because <reason> . But let's still <disclaimer> . below is what I currently have (its ugly...) boolean complete = false; int begin = 0; int end = 0; while (complete == false) { if (s.charAt(end) == '<'){ stack.add(new Terminal(s.substring(begin, end))); begin = end; } else if (s.charAt(end) == '>') { stack.add(new NonTerminal(s.substring(begin, end))); begin = end; end++; } else if (end == s.length()){ if (isTerminal(getSubstring(s, begin, end))){ stack.add(new Terminal(s.substring(begin, end))); } else { stack.add(new NonTerminal(s.substring(begin, end))); } complete = true; } end++;

  • Handling element collisions on importing/including XML schemas

    - by eggyal
    Given schema definitions that define the same element differently, can one import/include both definitions and reference them independently from within a third schema definition? For example, given: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <element name="message" type="boolean"/> </schema> and: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <element name="message" type="date"/> </schema> Can one construct the following: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <complexType name="booleanMessageType"> <xs:sequence> <!-- reference to first definition here --> </xs:sequence> </complexType> <complexType name="dateMessageType"> <xs:sequence> <!-- reference to second definition here --> </xs:sequence> </complexType> </schema>

  • Android Custom Adapter with Bar Progress

    - by xger86x
    Hi, i have a custom adapter for an arraylist. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <ProgressBar android:id="@+id/downloadprogress" style="?android:attr/progressBarStyleHorizontal" android:layout_width="200dip" android:layout_height="wrap_content" android:max="100" android:progress="50" android:secondaryProgress="75" /> <TextView android:id="@+id/tripsname" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout> but when i try to access to the progress bar in the adapter private class MyAdapter extends ArrayAdapter<Trip> { int resource; public MyAdapter(Context context, int resource, ArrayList<Trip> items) { super(context, resource,items); this.resource=resource; } @Override public View getView(int position, View convertView, ViewGroup parent) { LinearLayout tripListItemView; final Trip t = getItem(position); String name = t.getName(); boolean offline = t.isOffline() ; if(convertView==null) { tripListItemView = new LinearLayout(getContext()); String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi; vi = (LayoutInflater)getContext().getSystemService(inflater); vi.inflate(resource, tripListItemView, true); } else { tripListItemView = (LinearLayout) convertView; } setProgressBarVisibility(true); View v = findViewById(R.id.downloadprogress); ProgressBar progressHorizontal = (ProgressBar) findViewById(R.id.downloadprogress); it always return null, like it doesn't find the progress bar. However, the progress bar is shown in the list, but i need to access to it inside the adapter. Anybody knows the solution? Thanks

  • Update existing Preference-item in a PreferenceActivity upon returning from a (sub)PreferenceScreen

    - by aioobe
    I have a PreferenceActivity with a bunch of (Sub)PreferenceScreens. Each such (Sub)PreferenceScreen represents an account and has the account-username as its title. PreferenceScreen root = mgr.createPreferenceScreen(this); for (MyAccountClass account : myAccounts) { final PreferenceScreen accScreen = mgr.createPreferenceScreen(this); accScreen.setTitle(account.getUsername()); // add Preferences to the accScreen // (for instance a "change username"-preference) ... root.add(accScreen); } As the user enters sub-PreferenceScreen, and edits the account user-name, I want the outer PreferenceScreen to update it's PreferenceScreen-title for the account in question. I've tried to add... usernamePref.setOnPreferenceChangeListener(new OnPreferenceChangeListener() { public boolean onPreferenceChange(Preference preference, Object newValue) { accScreen.setTitle(newValue.toString()); return true; } }); ...but the accScreen.setTitle does not seem to take effect on the outer PreferenceScreen. I've note that calling onContentChanged(); actually makes it work, but I realize that this is probably not the preferred way of doing it. I suspect I should call postInvalidate() on some view somewhere, but I really can't figure out on what view and when to do it. http://stackoverflow.com/questions/2396153/preferencescreen-androidsummary-update may be experiening the same problem as me. Any help appreciated.

  • How to keep track of a private messaging system using MongoDB?

    - by luckytaxi
    Take facebook's private messaging system where you have to keep track of sender and receiver along w/ the message content. If I were using MySQL I would have multiple tables, but with MongoDB I'll try to avoid all that. I'm trying to come up with a "good" schema that can scale and is easy to maintain. If I were using mysql, I would have a separate table to reference the user and and message. See below ... profiles table user_id first_name last_name message table message_id message_body time_stamp user_message_ref table user_id (FK) message_id (FK) is_sender (boolean) With the schema listed above, I can query for any messages that "Bob" may have regardless if he's the recipient or sender. Now how to turn that into a schema that works with MongoDB. I'm thinking I'll have a separate collection to hold the messages. Problem is, how can I differentiate between the sender and the recipient? If Bob logs in, what do I query against? Depending on whether Bob initiated the email, I don't want to have to query against "sender" and "receiver" just to see if the message belongs to the user.

  • Clearing canvas with Canvas.drawColor()

    - by strangeInAStrangerLand
    I'm attempting to change the background image of a custom View with some success. The image will change but the problem is that I still see traces of the old image. When I attempt to clear the canvas before drawing the new image, it doesn't appear to work. I create a bitmap to store the image. When changing the image, I call Canvas.drawColor() before drawing the new image but the old image persists. I've tried drawColor(0), drawColor(Color.BLACK), c.drawColor(0, PorterDuff.Mode.CLEAR), and none of the above works. As such, I had to post this for review from more experienced minds than mine. The actual code is as follows: private int bgnd; private boolean switching; public void setBgnd(int incoming){ switching = true; switch (incoming){ case R.drawable.image1: bgnd = incoming; this.invalidate(); break; case R.drawable.image2: bgnd = incoming; this.invalidate(); break; } } protected void onDraw(Canvas c){ if(switching == true){ Bitmap b = BitmapFactory.decodeResource(getResources(), bgnd); c.drawColor(0, PorterDuff.Mode.CLEAR); c.drawBitmap(b, 0, 0, null); switching = false; }else{ Bitmap b = BitmapFactory.decodeResource(getResources(), bgnd); c.drawBitmap(b, 0, 0, null); } }

  • How can I filter a JTable?

    - by Jonas
    I would like to filter a JTable, but I don't understand how I can do it. I have read How to Use Tables - Sorting and Filtering and I have tried with the code below, but with that filter, no rows at all is shown in my table. And I don't understand what column it is filtered on. private void myFilter() { RowFilter<MyModel, Object> rf = null; try { rf = RowFilter.regexFilter(filterFld.getText(), 0); } catch (java.util.regex.PatternSyntaxException e) { return; } sorter.setRowFilter(rf); } MyModel has three columns, the first two are strings and the last column is of type Integer. How can I apply the filter above, consider the text in filterFld.getText() and only filter the rows where the text is matched on the second column? I would like to show all rows that starts with the text specified by filterFld.getText(). I.e. if the text is APP then the JTable should contain the rows where the second column starts with APPLE, APPLICATION but not the rows where the second column is CAR, ORANGE. I have also tried with this filter: RowFilter<MyModel, Integer> itemFilter = new RowFilter<MyModel, Integer>(){ public boolean include(Entry<? extends MyModel, ? extends Integer> entry){ MyModel model = entry.getModel(); MyItem item = model.getRecord(entry.getIdentifier()); if (item.getSecondColumn().startsWith("APP")) { return true; } else { return false; } } }; How can I write a filter that is filtering the JTable on the second column, specified by my textfield?

  • Huge mysql table with Zend Framework

    - by Uffo
    I have a mysql table with over 4 million of data; well the problem is that SOME queries WORK and SOME DON'T it depends on the search term, if the search term has a big volume of data in the table than I get the following error: Fatal error: Allowed memory size of 1048576000 bytes exhausted (tried to allocate 75 bytes) in /home/****/public_html/Zend/Db/Statement/Pdo.php on line 290 I currently have Zend Framework cache for metadata enabled, I have index on all the fields from that table.The site is running on a dedicated server with 2gb of ram. I've also set memory limit to: ini_set("memory_limit","1000M"); Any other things that I can optimize? Those are the types of query that I'm currently using: $do = $this->select() ->where('branche LIKE ?','%'.mysql_escape_string($branche).'%') ->order('premium DESC'); } //For name if(empty($branche) && empty($plz)) { $do = $this->select("MATCH(`name`) AGAINST ('{$theString}') AS score") ->where('MATCH(`name`) AGAINST( ? IN BOOLEAN MODE)', $theString) ->order('premium DESC, score'); } And a few other, but they are pretty much the same. Best Regards

  • Multi-level inheritance with Implements on properties in VB.NET vs C#

    - by Ben McCormack
    Let's say I have 2 interfaces defined like so: public interface ISkuItem { public string SKU { get; set; } } public interface ICartItem : ISkuItem { public int Quantity { get; set; } public bool IsDiscountable { get; set; } } When I go to implement the interface in C#, VS produces the following templated code: public class CartItem : ICartItem { #region ICartItem Members public int Quantity { get {...} set {...} } public bool IsDiscountable { get {...} set {...} } #endregion #region ISkuItem Members public string SKU { get {...} set {...} } #endregion } In VB.NET, the same class is built out like so: Public Class CartItem Implements ICartItem Public Property IsDiscountable As Boolean Implements ICartItem.IsDiscountable 'GET SET' End Property Public Property Quantity As Integer Implements ICartItem.Quantity 'GET SET' End Property Public Property SKU As String Implements ISkuItem.SKU 'GET SET' End Property End Class VB.NET explicitly requires you to add Implements IInterfaceName.PropertyName after each property that gets implemented whereas C# simply uses regions to indicate which properties and methods belong to the interface. Interestingly in VB.NET, on the SKU property, I can specify either Implements ISkuItem.SKU or Implements ICartItem.SKU. Although the template built by VS defaults to ISkuItem, I can also specify ICartItem if I want. Oddly, because C# only uses regions to block out inherited properties, it seems that I can't explicitly specify the implementing interface of SKU in C# like I can in VB.NET. My question is: Is there any importance behind being able to specify one interface or another to implement properites in VB.NET, and if so, is there a way to mimic this functionality in C#?

  • Issue intercepting property in Silverlight application

    - by joblot
    I am using Ninject as DI container in a Silverlight application. Now I am extending the application to support interception and started integrating DynamicProxy2 extension for Ninject. I am trying to intercept call to properties on a ViewModel and ending up getting following exception: “Attempt to access the method failed: System.Reflection.Emit.DynamicMethod..ctor(System.String, System.Type, System.Type[], System.Reflection.Module, Boolean)” This exception is thrown when invocation.Proceed() method is called. I tried two implementations of the interceptor and they both fail public class NotifyPropertyChangedInterceptor: SimpleInterceptor { protected override void AfterInvoke(IInvocation invocation) { var model = (IAutoNotifyPropertyChanged)invocation.Request.Proxy; model.OnPropertyChanged(invocation.Request.Method.Name.Substring("set_".Length)); } } public class NotifyPropertyChangedInterceptor: IInterceptor { public void Intercept(IInvocation invocation) { invocation.Proceed(); var model = (IAutoNotifyPropertyChanged)invocation.Request.Proxy; model.OnPropertyChanged(invocation.Request.Method.Name.Substring("set_".Length)); } } I want to call OnPropertyChanged method on the ViewModel when property value is set. I am using Attribute based interception. [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)] public class NotifyPropertyChangedAttribute : InterceptAttribute { public override IInterceptor CreateInterceptor(IProxyRequest request) { if(request.Method.Name.StartsWith("set_")) return request.Context.Kernel.Get<NotifyPropertyChangedInterceptor>(); return null; } } I tested the implementation with a Console Application and it works alright. I also noted in Console Application as long as I had Ninject.Extensions.Interception.DynamicProxy2.dll in same folder as Ninject.dll I did not have to explicitly load DynamicProxy2Module into the Kernel, where as I had to explicitly load it for Silverlight application as follows: IKernel kernel = new StandardKernel(new DIModules(), new DynamicProxy2Module()); Could someone please help? Thanks

  • Can SOTI's MobiControl software interfere with an ASP.Net web service?

    - by MusiGenesis
    We have a set of WinMo (5.0) devices running a .NET CF application that talks to an ASP.Net web service running on a server. The devices connect to the network either via ActiveSync through a networked PC or directly to the network via an Ethernet dongle. In our development environment, the communication between devices and web service is 100% reliable. In our production environment, the communications are failing erratically and unpredictably. Sometimes calls to the web service (even to a simple test call that just returns a boolean) begin failing every time on a particular device, with the error message "Could not establish connection to network." This is usually fixed by flip-flopping the selected combo box values on the SETTINGS | NETWORKS screen. Sometimes calls on a particular device begin failing with a generic "WebException" message. The fix for this problem (so far) is either to reset the device (i.e. reinstall the OS) or else it just can't be fixed on some devices. To the best of our knowledge, everything about the DEV and PROD systems are the same (same server and device specs). The most obvious difference to us is that the PROD devices are all controlled by SOTI's MobiControl (which is server-side software that communicates with a SOTI client application installed on each device), whereas our DEV environment does not have SOTI installed anywhere (obviously we should have it there as well - long story). Does anybody have any experience with SOTI MobiControl and/or know of any documented problems where SOTI interferes with other communication mechanisms on a device?
