  • Ontology and same individuals

    - by blueomega
    I am having a problem with "same individuals property" in protege, when i run a reasoner (pellet 1.5 or fact++) Lets take ontology example thing has class sons A and B, A has sons C and D. B, C and D have individuals of the same class. Cant i say a individual C is "same individual" as individual B, and then add also individual D is "same individual" as individual B. Wich is true, they have diferent names, but they are same individual.. Why does it only work when i set individual B has "same individual" of type C or D? The protege error is "InconsistentOntologyException:Fact++.Kernel: inconsistent Ontology" and pellet says ontology is inconsistent. EDIT: Seems its a more deep rooted problem, this example works :(, gonna keep checking. EDIT2: After some more experimenting, seems its a conflict with DataType properties. They all share a DataType properties with same name. In the example domain of property would be A and range string. Any idea how to solve?

  • Cannot figure out how to take in generic parameters for an Enterprise Framework library sql statemen

    - by KallDrexx
    I have written a specialized class to wrap up the enterprise library database functionality for easier usage. The reasoning for using the Enterprise Library is because my applications commonly connect to both oracle and sql server database systems. My wrapper handles both creating connection strings on the fly, connecting, and executing queries allowing my main code to only have to write a few lines of code to do database stuff and deal with error handling. As an example my ExecuteNonQuery method has the following declaration: /// <summary> /// Executes a query that returns no results (e.g. insert or update statements) /// </summary> /// <param name="sqlQuery"></param> /// <param name="parameters">Hashtable containing all the parameters for the query</param> /// <returns>The total number of records modified, -1 if an error occurred </returns> public int ExecuteNonQuery(string sqlQuery, Hashtable parameters) { // Make sure we are connected to the database if (!IsConnected) { ErrorHandler("Attempted to run a query without being connected to a database.", ErrorSeverity.Critical); return -1; } // Form the command DbCommand dbCommand = _database.GetSqlStringCommand(sqlQuery); // Add all the paramters foreach (string key in parameters.Keys) { if (parameters[key] == null) _database.AddInParameter(dbCommand, key, DbType.Object, null); else _database.AddInParameter(dbCommand, key, DbType.Object, parameters[key].ToString()); } return _database.ExecuteNonQuery(dbCommand); } _database is defined as private Database _database;. Hashtable parameters are created via code similar to p.Add("@param", value);. the issue I am having is that it seems that with enterprise library database framework you must declare the dbType of each parameter. This isn't an issue when you are calling the database code directly when forming the paramters but doesn't work for creating a generic abstraction class such as I have. In order to try and get around that I thought I could just use DbType.Object and figure the DB will figure it out based on the columns the sql is working with. Unfortunately, this is not the case as I get the following error: Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query Is there any way to use generic parameters in a wrapper class or am I just going to have to move all my DB code into my main classes?

  • Eager fetching of children with JDO (Datanucleus)

    - by Jan
    Hi, can JDO fetch all children of a database model at once? Like: class Parent { @Persistent(mappedBy="parent") private Set<Children> children; } class Children { @Persistent private Parent parent; @Persistent private String name; } In my case, I have a large number of Parents which I fetch at once. Accessing their children then takes a lot of time because they are fetched lazily. Does JDO (Datanucleus) support their fetching at once, togehter with the Parents? I also tried to fetch all Children independantly with another quey and put them into the Level2 cache afterwards, but still they are fetched (maybe jdo doesn't know about their relationship? Because the ForeignKey (parent-id) hasn't been fetched at first?) Any ideas how to read the data structure faster? Cheers, Jan

  • how to modify this jquery syntax

    - by Gandalf StormCrow
    Hi all, this example below works when hover event is trigered and when its not, its working for elements already in DOM, but when element created dynamically it doesn't work, I realize I need to use jQuery live() or delegate() for this, the thing is I tried to modify it and its not producing the results as expected, here is the working code : $(".sidebar li").hover( function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Here is the bit when I wanted to add live but it's not producing correct results : $(".sidebar li").live('hover', function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Where did I made mistake, thank you

  • SelfReferenceProperty vs. ListProperty Google App Engine

    - by John
    Hi All, I am experimenting with the Google App Engine and have a question. For the sake of simplicity, let's say my app is modeling a computer network (a fairly large corporate network with 10,000 nodes). I am trying to model my Node class as follows: class Node(db.Model): name = db.StringProperty() neighbors = db.SelfReferenceProperty() Let's suppose, for a minute, that I cannot use a ListProperty(). Based on my experiments to date, I can assign only a single entity to 'neighbors' - and I cannot use the "virtual" collection (node_set) to access the list of Node neighbors. So... my questions are: Does SelfReferenceProperty limit you to a single entity that you can reference? If I instead use a ListProperty, I believe I am limited to 5,000 keys, which I need to exceed. Thoughts? Thanks, John

  • How can I share Configuration Settings across multiple projects in Visual Studio?

    - by Muneeb
    Ok I know this may be a design issue, so I would love to have remarks on that as well. I have a Visual Studio web application solution. I have three projects as UserInterface, BusinessLogic and DataAccess. I had to store some user defined settings and I created configSections in the config file. I access these configSections through classes which inherit from .NET's ConfigurationSection base class. So in short for every project I had a separate configSection and for that corresponding configSection I had a class in that project inheriting from ConfigurationSection to access the config section settings. This works all sweet. But the problem arises if there is any setting which I need to use across multiple projects. So If I need to use a setting defined in UserInterface project configSection in, let say, BusinessLogic project I have to actually make a copy of that setting in the BusinessLogic's configSection. This ends up having the same setting copied across multiple configSections. Isn't this a bit too redundant?

  • Ajax call in a jQuery plugin not working properly

    - by Saneef
    I'm trying to create a jQuery plugin, inside I need to do an AJAX call to load an xml. jQuery.fn.imagetags = function(options) { s = jQuery.extend({ height:null, width:null, url:false, callback:null, title:null, }, options); return this.each(function(){ obj = $(this); //Initialising the placeholder $holder = $('<div />') .width(s.width).height(s.height) .addClass('jimageholder') .css({ position: 'relative', }); obj.wrap($holder); $.ajax({ type: "GET", url: s.url, dataType: "xml", success:function(data){ initGrids(obj,data,s.callback,s.title); } , error: function(data) { alert("Error loading Grid data."); }, }); function initGrids(obj, data,callback,gridtitle){ if (!data) { alert("Error loading Grid data"); } $("gridlist gridset",data).each(function(){ var gridsetname = $(this).children("setname").text(); var gridsetcolor = ""; if ($(this).children("color").text() != "") { gridsetcolor = $(this).children("color").text(); } $(this).children("grid").each(function(){ var gridcolor = gridsetcolor; //This colour will override colour set for the grid set if ($(this).children("color").text() != "") { gridcolor = $(this).children("color").text(); } //addGrid(gridsetname,id,x,y,height,width) addGrid( obj, gridsetname, $(this).children("id").text(), $(this).children("x").text(), $(this).children("y").text(), $(this).children("height").text(), $(this).children("width").text(), gridcolor, gridtitle ); }); }); } function addGrid(obj,gridsetname,id,x,y,height,width,color,gridtitle){ //To compensate for the 2px border height-=4; width-=4; $grid = $('<div />') .addClass(gridsetname) .attr("id",id) .addClass('gridtag') .imagetagsResetHighlight() .css({ "bottom":y+"px", "left":x+"px", "height":height+"px", "width":width+"px", }); if(gridtitle != null){ $grid.attr("title",gridtitle); } if(color != ""){ $grid.css({ "border-color":color, }); } obj.after($grid); } }); } The above plugin I bind with 2 DOM objects and loads two seperate XML files but the callback function is run only on the last DOM object using both loaded XML files. How can I fix this, so that the callback is applied on the corresponding DOMs. Is the above ajax call is correct? Sample usage: <script type="text/javascript"> $(function(){ $(".romeo img").imagetags({ height:500, width:497, url: "sample-data.xml", title: "Testing...", callback:function(id){ console.log(id); }, }); }); </script> <div class="padding-10 min-item background-color-black"> <div class="romeo"><img src="images/samplecontent/test_500x497.gif" alt="Image"> </div> </div> <script type="text/javascript"> $(function(){ $(".romeo2 img").imagetags({ height:500, width:497, url: "sample-data2.xml", title: "Testing...", callback:function(id){ console.log(id); }, }); }); </script> <div class="padding-10 min-item background-color-black"> <div class="romeo2"><img src="images/samplecontent/test2_500x497.gif" alt="Image"> </div> </div> Here is the sample XML data: <?xml version="1.0" encoding="utf-8"?> <gridlist> <gridset> <setname>gridset4</setname> <color>#00FF00</color> <grid> <color>#FF77FF</color> <id>grid2-324</id> <x>300</x> <y>300</y> <height>60</height> <width>60</width> </grid> </gridset> <gridset> <setname>gridset3</setname> <color>#00FF00</color> <grid> <color>#FF77FF</color> <id>grid2-212</id> <x>300</x> <y>300</y> <height>100</height> <width>100</width> </grid> <grid> <color>#FF77FF</color> <id>grid2-1212</id> <x>200</x> <y>10</y> <height>200</height> <width>10</width> </grid> </gridset> </gridlist>

  • Deterministic key serialization

    - by Mike Boers
    I'm writing a mapping class which uses SQLite as the storage backend. I am currently allowing only basestring keys but it would be nice if I could use a couple more types hopefully up to anything that is hashable (ie. same requirements as the builtin dict). To that end I would like to derive a deterministic serialization scheme. Ideally, I would like to know if any implementation/protocol combination of pickle is deterministic for hashable objects (e.g. can only use cPickle with protocol 0). I noticed that pickle and cPickle do not match: >>> import pickle >>> import cPickle >>> def dumps(x): ... print repr(pickle.dumps(x)) ... print repr(cPickle.dumps(x)) ... >>> dumps(1) 'I1\n.' 'I1\n.' >>> dumps('hello') "S'hello'\np0\n." "S'hello'\np1\n." >>> dumps((1, 2, 'hello')) "(I1\nI2\nS'hello'\np0\ntp1\n." "(I1\nI2\nS'hello'\np1\ntp2\n." Another option is to use repr to dump and ast.literal_eval to load. This would only be valid for builtin hashable types. I have written a function to determine if a given key would survive this process (it is rather conservative on the types it allows): def is_reprable_key(key): return type(key) in (int, str, unicode) or (type(key) == tuple and all( is_reprable_key(x) for x in key)) The question for this method is if repr itself is deterministic for the types that I have allowed here. I believe this would not survive the 2/3 version barrier due to the change in str/unicode literals. This also would not work for integers where 2**32 - 1 < x < 2**64 jumping between 32 and 64 bit platforms. Are there any other conditions (ie. do strings serialize differently under different conditions)? (If this all fails miserably then I can store the hash of the key along with the pickle of both the key and value, then iterate across rows that have a matching hash looking for one that unpickles to the expected key, but that really does complicate a few other things and I would rather not do it.) Any insights?

  • jquery hasClass "active" on ul#navigation li on page load not working

The opacity rollover works a treat, but I'd like my "active" page to have 100% opacity, but I can't seem to get it to work..what am I doing wrong? the link in questions HTML is: <ul id="navigation"> <li class="active"><a href="page.htm"></a></li> </ul> the nav works perfect minus my "active" class so I think I provided all the necessary code. thank you.

  • Automatic database generation / migration with perl

    - by pistacchio
    Hi, In Ror or Django or web2py you can "describe" a database (as a set of classes that remaps to tables) and the framework (having being provided with a connection string to the desired database) generates the tables, fields, relations and in the case of RoR and web2py it also keeps it up-to-date (eg, removing a class drops the table, adding a property to the class triggers an "alter table add" etc). Is there any perl module that does the same? Eg, it takes the YAML / XML / JSON description of a database as input and modifies / generates the database accordingly? Thanks in advance.

  • When should I open and close a connection to SQL Server

    - by Martin
    I have a simple static class with a few methods in it. Each of those methods open a SqlConnection, query the database and close the connection. This way, I am sure that I always close the connection to the database, but on the other hand, I don't like to always open and close connection. Below is an example of what my methods look like. public static void AddSomething(string something) { using (SqlConnection connection = new SqlConnection("...")) { connection.Open(); // ... connection.Close(); } } Considering that the methods are inside a static class, should I have a static member containing a single SqlConnection? How and when should I drop it? What are the best practices?

  • Drupal 6: Printing Unadulterated Primary Links and all children...

    - by dcolumbus
    How in the WORLD is possible? I swear, I've read the equivalent of 3 encyclopedias to no avail. I've tried solutions within regions, page.tpl.php and blocks. None of them give me what I need... and I know there are so many other people that need this too! I've come to the conclusion that I want to print out the menu within my page.tpl.php ... so no block solutions, please. I want to be able to loop through the primary menu links (AND children) and rewrite the output so that there's no default Drupal class tagging. The closest I've found is this example: <?php if (is_array($primary_links)) : ?> <ul id="sliding-navigation"> <?php foreach ($primary_links as $link): ?> <li class="sliding-element"><?php $href = $link['href'] == "<front>" ? base_path() : base_path() . drupal_get_path_alias($link['href']); print "<a href='" . $href . "'>" . $link['title'] . "</a>"; ?></li> <?php endforeach; ?> </ul> <?php endif; ?> As you can see, links are being reprinted with a custom UL and LI class ... that's GREAT! However, no children are being printed. How would I extend this code so that all children are a part of the list? NOTE: I don't want the children to only appear on their parent page, they must be present all the time. Otherwise, the drop-down menu I have planned is useless. I sincerely thank you in advance to lessening my gargantuan headache!

  • C++0x: How can I access variadic tuple members by index at runtime?

    I have written the following basic Tuple template: template <typename... T> class Tuple; template <uintptr_t N, typename... T> struct TupleIndexer; template <typename Head, typename... Tail> class Tuple<Head, Tail...> : public Tuple<Tail...> { private: Head element; public: template <uintptr_t N> typename TupleIndexer<N, Head, Tail...>::Type& Get() { return TupleIndexer<N, Head, Tail...>::Get(*this); } uintptr_t GetCount() const { return sizeof...(Tail) + 1; } private: friend struct TupleIndexer<0, Head, Tail...>; }; template <> class Tuple<> { public: uintptr_t GetCount() const { return 0; } }; template <typename Head, typename... Tail> struct TupleIndexer<0, Head, Tail...> { typedef Head& Type; static Type Get(Tuple<Head, Tail...>& tuple) { return tuple.element; } }; template <uintptr_t N, typename Head, typename... Tail> struct TupleIndexer<N, Head, Tail...> { typedef typename TupleIndexer<N - 1, Tail...>::Type Type; static Type Get(Tuple<Head, Tail...>& tuple) { return TupleIndexer<N - 1, Tail...>::Get(*(Tuple<Tail...>*) &tuple); } }; It works just fine, and I can access elements in array-like fashion by using tuple.Get<Index() - but I can only do that if I know the index at compile-time. However, I need to access elements in the tuple by index at runtime, and I won't know at compile-time which index needs to be accessed. Example: int chosenIndex = getUserInput(); cout << "The option you chose was: " << tuple.Get(chosenIndex) << endl; What's the best way to do this?

  • Java unit test coverage numbers do not match.

    - by Dan
    Below is a class I have written in a web application I am building using Java Google App Engine. I have written Unit Tests using TestNG and all the tests pass. I then run EclEmma in Eclipse to see the test coverage on my code. All the functions show 100% coverage but the file as a whole is showing about 27% coverage. Where is the 73% uncovered code coming from?

  • ArrayList access

    - by Ricky McQuesten
    So once again I have a question about this program. I want to store transactions that are made in an arraylist and then have an option in the case menu where I can print out those that are stored. I have been researching online and have been unable to find a solution to this, so is this possible and how would I go about doing this? I also want to attach a timestamp to each transaction as well. Here is the code I have so far. So my question is how would I add a timestamp to each withdrawal or deposit, and how would I store each transaction in array list? import java.util.*; public class BankAccount extends Money { //inheritence static String name; public static int acctNum; public static double balance, amount; BankAccount(String name, int accNo, double bal) { this.name = name; this.acctNum = accNo; this.balance = bal; } void display() { System.out.println("Your Name:" + name); System.out.println("Your Account Number:" + acctNum); System.out.println("Your Current Account Balance:" + Money.getBalance()); } void displayBalance() { System.out.println("Balance:" + balance); } } import java.util.Scanner; /** * * @author Ricky */ public class Money { public static int accountNumber; public static double balance; static double amount; static String name; public void setDeposit(double amount) { balance = balance + amount; if (amount < 0) { System.out.println("Invalid"); } } public double getDeposit() { return 1; } public void setBalance(double b) { balance = b; } public static double getBalance() { return balance; } public void setWithdraw(double amount) { if (balance < amount) { System.out.println("Not enough funds."); } else if(amount < 0) { System.out.println("Invalid"); } else { balance = balance - amount; } } public double getWithdraw() { return 1; } } import java.util.*; public class Client { public static void main(String args[]) { int n = 0; int count; String trans; ArrayList<String> transaction= new ArrayList<String>(n); Scanner input = new Scanner(System.in); System.out.println("Welcome to First National Bank"); System.out.println("Please enter your name: "); String cusName = input.nextLine(); System.out.println("You will now be assigned an account number."); Random randomGenerator = new Random(); int accNo = randomGenerator.nextInt(100000); //random number System.out.println("Your account number is: " + accNo); System.out.println("Please enter your initial account balance: "); Double balance = input.nextDouble(); BankAccount b1 = new BankAccount(cusName, accNo, balance); b1.setBalance(balance); int menu; /*System.out.println("Menu"); System.out.println("1. Deposit Amount"); System.out.println("2. Withdraw Amount"); System.out.println("3. Display Information"); System.out.println("4. Exit");*/ boolean quit = false; do { System.out.println("*******Menu*******"); System.out.println("1. Deposit Amount"); // menu to take input from user System.out.println("2. Withdraw Amount"); System.out.println("3. Display Information"); System.out.println("4. Exit"); System.out.print("Please enter your choice: "); menu = input.nextInt(); switch (menu) { case 1: System.out.print("Enter depost amount:"); b1.setDeposit(input.nextDouble()); b1.getDeposit(); transaction.add(trans); break; case 2: System.out.println("Current Account Balance=" + b1.getBalance()); System.out.print("Enter withdrawal amount:"); b1.setWithdraw(input.nextDouble()); b1.getWithdraw(); transaction.add(trans); break; // switch statments to do a loop case 3: b1.display(); break; case 4: quit = true; break; } } while (!quit); } } public class Date { static Date time = new Date(); }

  • How to populate JList with data from another JList

    - by Zhen Le
    I have a MySQL database which contains data i would like to populate into a JList in my java program. I have two JList, one which is fill with Events Title and the second is to be fill with Guest Name. What i would like is when the user click on any of the Events Title, the second JList will show all the Guest Name that belong to that Event. I have already successfully populate the first JList with all the Events Title. What I'm having trouble with is when the user click on the Events Title, the Guests Name will show twice on the second JList. How can i make it to show only once? Here is what i got so far... Java Class private JList getJListEvents() { if (jListEvents == null) { jListEvents = new JList(); Border border = BorderFactory.createTitledBorder(BorderFactory.createBevelBorder(1, Color.black, Color.black), "Events", TitledBorder.LEFT, TitledBorder.TOP); jListEvents.setBorder(border); jListEvents.setModel(new DefaultListModel()); jListEvents.setBounds(new Rectangle(15, 60, 361, 421)); Events lEvents = new Events(); lEvents.loadEvents(jListEvents); jListEvents.addListSelectionListener(new ListSelectionListener(){ public void valueChanged(ListSelectionEvent e){ EventC eventC = new EventC(); //eventC.MonitorRegDetailsInfo(jListEvents, jTextFieldEventName, jTextFieldEventVenue, jTextFieldEventDate, jTextFieldEventTime, jTextAreaEventDesc); //eventC.MonitorRegPackageInfo(jListEvents, jTextFieldBallroom, jTextFieldBallroomPrice, jTextFieldMeal, jTextFieldMealPrice, jTextFieldEntertainment, jTextFieldEntertainmentPrice); eventC.MonitorRegGuest(jListEvents, jListGuest); } }); } return jListEvents; } Controller Class public void MonitorRegGuest(JList l, JList l2){ String event = l.getSelectedValue().toString(); Events retrieveGuest = new Events(event); retrieveGuest.loadGuests(l2); } Class with all the sql statement public void loadGuests(JList l){ ResultSet rs = null; ResultSet rs2 = null; ResultSet rs3 = null; MySQLController db = new MySQLController(); db.getConnection(); String sqlQuery = "SELECT MemberID FROM event WHERE EventName = '" + EventName + "'"; try { rs = db.readRequest(sqlQuery); while(rs.next()){ MemberID = rs.getString("MemberID"); } } catch (SQLException e) { e.printStackTrace(); } String sqlQuery2 = "SELECT GuestListID FROM guestlist WHERE MemberID = '" + MemberID + "'"; try { rs2 = db.readRequest(sqlQuery2); while(rs2.next()){ GuestListID = rs2.getString("GuestListID"); } } catch (SQLException e) { e.printStackTrace(); } String sqlQuery3 = "SELECT Name FROM guestcontact WHERE GuestListID = '" + GuestListID + "'"; try { rs3 = db.readRequest(sqlQuery3); while(rs3.next()){ ((DefaultListModel)l.getModel()).addElement(rs3.getString("Name")); } } catch (SQLException e) { e.printStackTrace(); } db.terminate(); } Thanks in advance!

  • Custom login in Django

    - by alpgs
    Django newbie here. I wrote simplified login form which takes email and password. It works great if both email and password are supplied, but if either is missing i get KeyError exception. According to django documentation this should never happen: By default, each Field class assumes the value is required, so if you pass an empty value -- either None or the empty string ("") -- then clean() will raise a ValidationError exception I tried to write my own validators for fields (clean_email and clean_password), but it doesn't work (ie I get KeyError exception). What am I doing wrong? class LoginForm(forms.Form): email = forms.EmailField(label=_(u'Your email')) password = forms.CharField(widget=forms.PasswordInput, label=_(u'Password')) def clean_email(self): data = self.cleaned_data['email'] if not data: raise forms.ValidationError(_("Please enter email")) return data def clean_password(self): data = self.cleaned_data['password'] if not data: raise forms.ValidationError(_("Please enter your password")) return data def clean(self): try: username = User.objects.get(email__iexact=self.cleaned_data['email']).username except User.DoesNotExist: raise forms.ValidationError(_("No such email registered")) password = self.cleaned_data['password'] self.user = auth.authenticate(username=username, password=password) if self.user is None or not self.user.is_active: raise forms.ValidationError(_("Email or password is incorrect")) return self.cleaned_data

  • Documenting logic in javadoc

    - by smayers81
    I have a question about where to document logic in javadocs. For example, I have the following method signature in an interface: public int getTotalAssociationsAsParent(Long id, Long type); The method returns associations where the given ID is the parent and the association is of type 'type'. ID is required, but if type passed in is NULL, then I will return ALL associations where the ID is the parent. My question is where should this type of logic be documented? I hesitate putting it in the javadoc of the interface because that sort of constrains all implementing classes to adhere to that logic. Maybe in the future, I'll have an Impl class that throws an IllegalArgumentException if type is NULL. However, if I put it in non-javadoc in the Impl class, then consumers of this method won't know how the method behaves with a NULL type.
