  • asp:login form does not submit when you hit enter

    - by Ben Liyanage
    I am having an issues while using the <asp:login> tag. When a user clicks the "login" button, the form will process correctly. However, when the user hits the enter key, the form self submits and does not process the login, whether it was correct information or not. I am using a combination of MasterPages, and Umbraco. My aspx code looks like this: <%@ Master Language="C#" MasterPageFile="/masterpages/AccountCenter.master" CodeFile="~/masterpages/Login.master.cs" Inherits="LoginPage" AutoEventWireup="true" %> <asp:Content ContentPlaceHolderID="RunwayMasterContentPlaceHolder" runat="server"> <div class="loginBox"> <div class="AspNet-Login-TitlePanel">Account Center Login</div> <asp:label id="output" runat="server"></asp:label> <asp:GridView runat="server" id="GridResults" AutoGenerateColumns="true"></asp:GridView> <asp:Login destinationpageurl="~/dashboard.aspx" ID="Login1" OnLoggedIn="onLogin" runat="server" TitleText="" FailureText="The login/password combination you provided is invalid." DisplayRememberMe="false"></asp:Login> </div> </asp:Content> In the actual rendered page, I see this javascript on the form: <form method="post" action="/dashboard.aspx?" onsubmit="javascript:return WebForm_OnSubmit();" id="aspnetForm"> That javascript function is defined as: <script type="text/javascript"> //<![CDATA[ function WebForm_OnSubmit() { if (typeof(ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) return false; return true; } //]]> </script> The javascript is always evaluating to True when it runs.

  • What do I name this class whose sole purpose is to report failure?

    - by Blair Holloway
    In our system, we have a number of classes whose construction must happen asynchronously. We wrap the construction process in another class that derives from an IConstructor class: class IConstructor { public: virtual void Update() = 0; virtual Status GetStatus() = 0; virtual int GetLastError() = 0; }; There's an issue with the design of the current system - the functions that create the IConstructor-derived classes are often doing additional work which can also fail. At that point, instead of getting a constructor which can be queried for an error, a NULL pointer is returned. Restructuring the code to avoid this is possible, but time-consuming. In the meantime, I decided to create a constructor class which we create and return in case of error, instead of a NULL pointer: class FailedConstructor : public IConstructor public: virtual void Update() {} virtual Status GetStatus() { return STATUS_ERROR; } virtual int GetLastError() { return m_errorCode; } private: int m_errorCode; }; All of the above this the setup for a mundane question: what do I name the FailedConstructor class? In our current system, FailedConstructor would indicate "a class which constructs an instance of Failed", not "a class which represents a failed attempt to construct another class". I feel like it should be named for one of the design patterns, like Proxy or Adapter, but I'm not sure which.

  • How do I setup Linq to SQL and WCF

    - by Jisaak
    So I'm venturing out into the world of Linq and WCF web services and I can't seem to make the magic happen. I have a VERY basic WCF web service going and I can get my old SqlConnection calls to work and return a DataSet. But I can't/don't know how to get the Linq to SQL queries to work. I'm guessing it might be a permissions problem since I need to connect to the SQL Database with a specific set of credentials but I don't know how I can test if that is the issue. I've tried using both of these connection strings and neither seem to give me a different result. <add name="GeoDataConnectionString" connectionString="Data Source=SQLSERVER;Initial Catalog=GeoData;Integrated Security=True" providerName="System.Data.SqlClient" /> <add name="GeoDataConnectionString" connectionString="Data Source=SQLSERVER;Initial Catalog=GeoData;User ID=domain\userName; Password=blahblah; Trusted_Connection=true" providerName="System.Data.SqlClient" /> Here is the function in my service that does the query and I have the interface add the [OperationContract] public string GetCity(int cityId) { GeoDataContext db = new GeoDataContext(); var city = from c in db.Cities where c.CITY_ID == 30429 select c.DESCRIPTION; return city.ToString(); } The GeoData.dbml only has one simple table in it with a list of city id's and city names. I have also changed the "Serialization Mode" on the DataContext to "Unidirectional" which from what I've read needs to be done for WCF. When I run the service I get this as the return: SELECT [t0].[DESCRIPTION] FROM [dbo].[Cities] AS [t0] WHERE [t0].[CITY_ID] = @p0 Dang, so as I'm writing this I realize that maybe my query is all messed up?

  • Custom Model Validator for MVC

    - by scottrakes
    I am trying to add a custom model validation at the property level but need to pass in two values. Below is my class definition and validation implementation. When it runs, the "value" in the IsValid method is always null. I can get this working at the class level but the property level is causing me issues. What am I missing? Event Class: public class Event { public int? EventID {get;set;} [ValidPURL("EventID", "PURLValue")] public string PURLValue { get; set; } ... } Validation Class [AttributeUsage(AttributeTargets.All, AllowMultiple = true, Inherited = true)] public sealed class ValidPURL : ValidationAttribute { private const string _defaultErrorMessage = "Web address already exist."; private readonly object _typeId = new object(); public ValidPURL(int eventID, string purlValue) : base(_defaultErrorMessage) { EventID = eventID; PURLValue = purlValue; } public int EventID { get; private set; } public string PURLValue { get; private set; } public override object TypeId { get { return _typeId; } } public override string FormatErrorMessage(string name) { return String.Format(CultureInfo.CurrentUICulture, ErrorMessageString, EventID, PURLValue); } public override bool IsValid(object value) { PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value); object eventIDValue = properties.Find(EventID, true /* ignoreCase */).GetValue(value); object purlValue = properties.Find(PURLValue, true /* ignoreCase */).GetValue(value); [Some Validation Logic against the database] return true; } } Thank for the help!

  • Django db encoding

    - by realshadow
    Hey, I have a little problem with encoding. The data in db is ok, when I select the data in php its ok. Problem comes when I get the data and try to print it in the template, I get - Å port instead of Šport, etc. Everything is set to utf-8 - in settings.py, meta tags in template, db table and I even have unicode method specified for the model, but nothing seems to work. I am getting pretty hopeless here... Here is some code: class Category_info(models.Model): objtree_label_id = models.AutoField(primary_key = True) node_id = models.IntegerField(unique = True) language_id = models.IntegerField() label = models.CharField(max_length = 255) type_id = models.IntegerField() class Meta: db_table = 'objtree_labels' def __unicode__(self): return self.label I have even tried with return u"%s" % self.label. Here is the view: def categories_list(request): categories_list = Category.objects.filter(parent_id = 1, status = 1) paginator = Paginator(categories_list, 10) try: page = int(request.GET.get('page', 1)) except ValueError: page = 1 try: categories = paginator.page(page) except (EmptyPage, InvalidPage): categories = paginator.page(paginator.num_pages) return render_to_response('categories_list.html', {'categories': categories}) Maybe I am just blind and/or stupid, but it just doesnt work. So any help is appreciated, thanks in advance. Regards

  • Can't add object to Array in jQuery's getJSON data function (scope issue)

    - by seo20
    I have a person object and wants to store it into a global ArrayCollection I have made. Works great in normal scope: var s = new ArrayCollection(); s.add(new person("Knud", "Mikkelsen", 35)); The problem is when I want to add people inside my jQuery function "mainFunction". I can't seem to get it right. I know it's something to do with scope and I have to wrap something in functions like in my ArrayCollection. Please help me - thanks a lot. function ArrayCollection() { var myArray = new Array; return { empty: function () { myArray.splice(0, myArray.length); }, add: function (myElement) { myArray.push(myElement); }, getAll: function () { return myArray; } } } function person(firstName, lastName, age) { this.firstName = firstName; this.lastName = lastName; this.age = parseInt(parseFloat(age)); } function mainFunction() { //.... var s = new ArrayCollection(); s.add(new person("Knud", "Mikkelsen", 35)); $.getJSON(url, function (data) { for (var x = 0; x < data.length; x++) { var myPerson = new person(data[x].FirstName.toString(), data[x].LastName.toString(), data[x].Age.toString()); s.add(myPerson); } }); alert(drawArray(s.getAll())); } function drawArray(myArray) { var v = ""; for (var i = 0; i < myArray.length; i++) { v += myArray[i].firstName + " " + myArray[i].lastName + " (" + myArray[i].age + ")\n"; } return v; }

  • Why Does This Maintainability Index Increase?

    - by Timothy
    I would be appreciative if someone could explain to me the difference between the following two pieces of code in terms of Visual Studio's Code Metrics rules. Why does the Maintainability Index increase slightly if I don't encapsulate everything within using ( )? Sample 1 (MI score of 71) public static String Sha1(String plainText) { using (SHA1Managed sha1 = new SHA1Managed()) { Byte[] text = Encoding.Unicode.GetBytes(plainText); Byte[] hashBytes = sha1.ComputeHash(text); return Convert.ToBase64String(hashBytes); } } Sample 2 (MI score of 73) public static String Sha1(String plainText) { Byte[] text, hashBytes; using (SHA1Managed sha1 = new SHA1Managed()) { text = Encoding.Unicode.GetBytes(plainText); hashBytes = sha1.ComputeHash(text); } return Convert.ToBase64String(hashBytes); } I understand metrics are meaningless outside of a broader context and understanding, and programmers should exercise discretion. While I could boost the score up to 76 with return Convert.ToBase64String(sha1.ComputeHash(Encoding.Unicode.GetBytes(plainText))), I shouldn't. I would clearly be just playing with numbers and it isn't truly any more readable or maintainable at that point. I am curious though as to what the logic might be behind the increase in this case. It's obviously not line-count.

  • Combining the streams:Web application

    - by Surendra J
    This question deals mainly with streams in web application in .net. In my webapplication I will display as follows: bottle.doc sheet.xls presentation.ppt stackof.jpg Button I will keep checkbox for each one to select. Suppose a user selected the four files and clicked the button,which I kept under. Then I instantiate clasees for each type of file to convert into pdf, which I wrote already and converted them into pdf and return them. My problem is the clases is able to read the data form URL and convert them into pdf. But I don't know how to return the streams and merge them. string url = @"url"; //Prepare the web page we will be asking for HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "GET"; request.ContentType = "application/mspowerpoint"; request.UserAgent = "Mozilla/4.0+(compatible;+MSIE+5.01;+Windows+NT+5.0"; //Execute the request HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //We will read data via the response stream Stream resStream = response.GetResponseStream(); //Write content into the MemoryStream BinaryReader resReader = new BinaryReader(resStream); MemoryStream PresentaionStream = new MemoryStream(resReader.ReadBytes((int)response.ContentLength)); //convert the presention stream into pdf and save it to local disk. But I would like to return the stream again. How can I achieve this any Ideas are welcome.

  • Is it bad practice to have state in a static class?

    - by Matthew
    I would like to do something like this: public class Foo { // Probably really a Guid, but I'm using a string here for simplicity's sake. string Id { get; set; } int Data { get; set; } public Foo (int data) { ... } ... } public static class FooManager { Dictionary<string, Foo> foos = new Dictionary<string, Foo> (); public static Foo Get (string id) { return foos [id]; } public static Foo Add (int data) { Foo foo = new Foo (data); foos.Add (foo.Id, foo); return foo; } public static bool Remove (string id) { return foos.Remove (id); } ... // Other members, perhaps events for when Foos are added or removed, etc. } This would allow me to manage the global collection of Foos from anywhere. However, I've been told that static classes should always be stateless--you shouldn't use them to store global data. Global data in general seems to be frowned upon. If I shouldn't use a static class, what is the right way to approach this problem? Note: I did find a similar question, but the answer given doesn't really apply in my case.

  • Rhinomocks DynamicMock question

  • Good way to maintain Muliple level selection menu list in J2ME

    - by geoaxis
    Hello, I need a good way to maintain multiple form level data for menue selection. So for example If I have A and B, each might Have 1 2 3 so A A1 A2 A3 B B1 B2 B3 And this can continue for long, so that I could have A - A1 - A1.1 - A1.1.1 -.... I have the following class in place, works ok But I suspect we could have better. I just need to perform selection ni a selection tree like Widget, but each level of selection comes in another form (in J2ME) import java.util.Vector; public class Tag { private String tag; private Vector childTags; private Tag parent; Tag(String tag, Vector childtag) { this.tag = tag; this.childTags= childTags; } public void setChildTags(Vector childTags) { this.childTags = childTags; } public Vector getChildTags() { return this.childTags; } public String getTag() { return this.tag; } public String toString(int depth) { String a =""; if(depth==0) { a = a + this.getTag(); } if(this.getChildTags()!= null) { for(int k=0;k <this.getChildTags().capacity(); k++) { for (int i=0; i<depth; i++ ) { a = a + ("-"); } a = a+ ( ((Tag)this.getChildTags().elementAt(k)).toString(depth++)); } } return a; } }

  • How to set HTMLField's widget's height in Admin?

    - by Georgie Porgie
    I have a HTMLField in a model as it's the laziest way to utilize tinymce widget in Admin. But the problem is that the textarea field doesn't have "rows" property set. So the textarea doesn't have enough height comfortable enough for editing in Admin. Is there any way to set the height of HTMLField without defining a ModelAdmin class? Update: I solved the problem by using the following code: def create_mce_formfield(db_field): return db_field.formfield(widget = TinyMCE( attrs = {'cols': 80, 'rows': 30}, mce_attrs = { 'external_link_list_url': reverse('tinymce.views.flatpages_link_list'), 'plugin_preview_pageurl': reverse('tinymce-preview', args= ('tinymce',)), 'plugins': "safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template", 'theme_advanced_buttons1': "save,newdocument,|,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,styleselect,formatselect,fontselect,fontsizeselect", 'theme_advanced_buttons2': "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,preview,|,forecolor,backcolor", 'theme_advanced_buttons3': "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,emotions,iespell,media,advhr,|,print,|,ltr,rtl,|,fullscreen", 'theme_advanced_buttons4': "insertlayer,moveforward,movebackward,absolute,|,styleprops,|,cite,abbr,acronym,del,ins,attribs,|,visualchars,nonbreaking,template,pagebreak", 'theme_advanced_toolbar_location': "top", 'theme_advanced_toolbar_align': "left", 'theme_advanced_statusbar_location': "bottom", 'theme_advanced_resizing': True, 'extended_valid_elements': "iframe[src|title|width|height|allowfullscreen|frameborder|webkitAllowFullScreen|mozallowfullscreen|allowFullScreen]", }, )) class TinyMCEFlatPageAdmin(FlatPageAdmin): def formfield_for_dbfield(self, db_field, **kwargs): if db_field.name == 'content': return create_mce_formfield(db_field) return super(TinyMCEFlatPageAdmin, self).formfield_for_dbfield(db_field, **kwargs)

  • How do I improve my performance with this singly linked list struct within my program?

    - by Jesus
    Hey guys, I have a program that does operations of sets of strings. We have to implement functions such as addition and subtraction of two sets of strings. We are suppose to get it down to the point where performance if of O(N+M), where N,M are sets of strings. Right now, I believe my performance is at O(N*M), since I for each element of N, I go through every element of M. I'm particularly focused on getting the subtraction to the proper performance, as if I can get that down to proper performance, I believe I can carry that knowledge over to the rest of things I have to implement. The '-' operator is suppose to work like this, for example. Declare set1 to be an empty set. Declare set2 to be a set with { a b c } elements Declare set3 to be a set with ( b c d } elements set1 = set2 - set3 And now set1 is suppose to equal { a }. So basically, just remove any element from set3, that is also in set2. For the addition implementation (overloaded '+' operator), I also do the sorting of the strings (since we have to). All the functions work right now btw. So I was wondering if anyone could a) Confirm that currently I'm doing O(N*M) performance b) Give me some ideas/implementations on how to improve the performance to O(N+M) Note: I cannot add any member variables or functions to the class strSet or to the node structure. The implementation of the main program isn't very important, but I will post the code for my class definition and the implementation of the member functions: strSet2.h (Implementation of my class and struct) // Class to implement sets of strings // Implements operators for union, intersection, subtraction, // etc. for sets of strings // V1.1 15 Feb 2011 Added guard (#ifndef), deleted using namespace RCH #ifndef _STRSET_ #define _STRSET_ #include <iostream> #include <vector> #include <string> // Deleted: using namespace std; 15 Feb 2011 RCH struct node { std::string s1; node * next; }; class strSet { private: node * first; public: strSet (); // Create empty set strSet (std::string s); // Create singleton set strSet (const strSet &copy); // Copy constructor ~strSet (); // Destructor int SIZE() const; bool isMember (std::string s) const; strSet operator + (const strSet& rtSide); // Union strSet operator - (const strSet& rtSide); // Set subtraction strSet& operator = (const strSet& rtSide); // Assignment }; // End of strSet class #endif // _STRSET_ strSet2.cpp (implementation of member functions) #include <iostream> #include <vector> #include <string> #include "strset2.h" using namespace std; strSet::strSet() { first = NULL; } strSet::strSet(string s) { node *temp; temp = new node; temp->s1 = s; temp->next = NULL; first = temp; } strSet::strSet(const strSet& copy) { if(copy.first == NULL) { first = NULL; } else { node *n = copy.first; node *prev = NULL; while (n) { node *newNode = new node; newNode->s1 = n->s1; newNode->next = NULL; if (prev) { prev->next = newNode; } else { first = newNode; } prev = newNode; n = n->next; } } } strSet::~strSet() { if(first != NULL) { while(first->next != NULL) { node *nextNode = first->next; first->next = nextNode->next; delete nextNode; } } } int strSet::SIZE() const { int size = 0; node *temp = first; while(temp!=NULL) { size++; temp=temp->next; } return size; } bool strSet::isMember(string s) const { node *temp = first; while(temp != NULL) { if(temp->s1 == s) { return true; } temp = temp->next; } return false; } strSet strSet::operator + (const strSet& rtSide) { strSet newSet; newSet = *this; node *temp = rtSide.first; while(temp != NULL) { string newEle = temp->s1; if(!isMember(newEle)) { if(newSet.first==NULL) { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = NULL; newSet.first = newNode; } else if(newSet.SIZE() == 1) { if(newEle < newSet.first->s1) { node *tempNext = newSet.first; node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = tempNext; newSet.first = newNode; } else { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = NULL; newSet.first->next = newNode; } } else { node *prev = NULL; node *curr = newSet.first; while(curr != NULL) { if(newEle < curr->s1) { if(prev == NULL) { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = curr; newSet.first = newNode; break; } else { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = curr; prev->next = newNode; break; } } if(curr->next == NULL) { node *newNode; newNode = new node; newNode->s1 = newEle; newNode->next = NULL; curr->next = newNode; break; } prev = curr; curr = curr->next; } } } temp = temp->next; } return newSet; } strSet strSet::operator - (const strSet& rtSide) { strSet newSet; newSet = *this; node *temp = rtSide.first; while(temp != NULL) { string element = temp->s1; node *prev = NULL; node *curr = newSet.first; while(curr != NULL) { if( element < curr->s1 ) break; if( curr->s1 == element ) { if( prev == NULL) { node *duplicate = curr; newSet.first = newSet.first->next; delete duplicate; break; } else { node *duplicate = curr; prev->next = curr->next; delete duplicate; break; } } prev = curr; curr = curr->next; } temp = temp->next; } return newSet; } strSet& strSet::operator = (const strSet& rtSide) { if(this != &rtSide) { if(first != NULL) { while(first->next != NULL) { node *nextNode = first->next; first->next = nextNode->next; delete nextNode; } } if(rtSide.first == NULL) { first = NULL; } else { node *n = rtSide.first; node *prev = NULL; while (n) { node *newNode = new node; newNode->s1 = n->s1; newNode->next = NULL; if (prev) { prev->next = newNode; } else { first = newNode; } prev = newNode; n = n->next; } } } return *this; }

  • MKAnnotationView for userLocation pin iPhone

    - by Mauricio Galindo
    I have an application that uses MKMapView and at some point in the app I need to remove all the current pins in the map using [mapView removeAnnotations:mapView.annotations] And then I want to show again the current user location mapView.showUserLocation = YES But I can only make it reappear as a regular pin, because the userLocation view class its not public so I cant return views of that type. Here is my code - (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>)annotation MKPinAnnotationView* annView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"currentloc"]; if (!annView) { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; annView.pinColor = MKPinAnnotationColorRed; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); if ([annotation isKindOfClass:[DraggableAnnotationAM class]] ) annView.draggable = YES; return annView; } else { if ([annotation isKindOfClass:[DraggableAnnotationAM class]] ) annView.draggable = YES; annView.annotation = annotation; return annView; } Also I have found through reflection that MKUserLocationView is the class that is used to display the current location, but because its not public its not safe to use and my app keeps crashing and Im sure theres a easier way. Is it possible to do what I want, or should I just never remove the user location annotation of the mapView? Thanks in advance

  • Qt/PyQt dialog with toggable fullscreen mode - problem on Windows

    - by Guard
    I have a dialog created in PyQt. It's purpose and functionality don't matter. The init is: class MyDialog(QWidget, ui_module.Ui_Dialog): def __init__(self, parent=None): super(MyDialog, self).__init__(parent) self.setupUi(self) self.installEventFilter(self) self.setWindowFlags(Qt.Dialog | Qt.WindowTitleHint) self.showMaximized() Then I have event filtering method: def eventFilter(self, obj, event): if event.type() == QEvent.KeyPress: key = event.key() if key == Qt.Key_F11: if self.isFullScreen(): self.setWindowFlags(self._flags) if self._state == 'm': self.showMaximized() else: self.showNormal() self.setGeometry(self._geometry) else: self._state = 'm' if self.isMaximized() else 'n' self._flags = self.windowFlags() self._geometry = self.geometry() self.setWindowFlags(Qt.Tool | Qt.FramelessWindowHint) self.showFullScreen() return True elif key == Qt.Key_Escape: self.close() return QWidget.eventFilter(self, obj, event) As can be seen, Esc is used for dialog hiding, and F11 is used for toggling full-screen. In addition, if the user changed the dialog mode from the initial maximized to normal and possibly moved the dialog, it's state and position are restored after exiting the full-screen. Finally, the dialog is created on the MainWindow action triggered: d = MyDialog(self) d.show() It works fine on Linux (Ubuntu Lucid), but quite strange on Windows 7: if I go to the full-screen from the maximized mode, I can't exit full-screen (on F11 dialog disappears and appears in full-screen mode again. If I change the dialog's mode to Normal (by double-clicking its title), then go to full-screen and then return back, the dialog is shown in the normal mode, in the correct position, but without the title line. Most probably the reason for both cases is the same - the setWindowFlags doesn't work. But why? Is it also possible that it is the bug in the recent PyQt version? On Ubuntu I have 4.6.x from apt, and on Windows - the latest installer from the riverbank site.

When I try to add @ManyToOne, schema creation fails with: org.hibernate.MappingException: Could not instantiate persister org.hibernate.persister.entity.SingleTableEntityPersister User.java: @Entity public class User { @Id private int id; public int getId() {return id;} public void setId(int id) {this.id = id;} @ManyToOne Department department; public Department getDepartment() {return department;} public void setDepartment(Department department) {this.department = department;} } Department.java @Entity public class Department { @Id private int departmentNumber; public int getDepartmentNumber() {return departmentNumber;} public void setDepartmentNumber(int departmentNumber) {this.departmentNumber = departmentNumber;} } hibernate.properties: hibernate.connection.driver_class=com.mysql.jdbc.Driver hibernate.connection.url=jdbc:mysql://localhost:3306/dbname hibernate.connection.username=user hibernate.connection.password=pass hibernate.connection.pool_size=5 hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect hibernate.hbm2ddl.auto=create init (throwing exception): ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().buildServiceRegistry(); sessionFactory = new MetadataSources( serviceRegistrY.addAnnotatedClass(Department.class).addAnnotatedClass(User.class).buildMetadata().buildSessionFactory(); exception throwed at init: org.hibernate.MappingException: Could not instantiate persister org.hibernate.persister.entity.SingleTableEntityPersister at org.hibernate.persister.internal.PersisterFactoryImpl.create(PersisterFactoryImpl.java:174) at org.hibernate.persister.internal.PersisterFactoryImpl.createEntityPersister(PersisterFactoryImpl.java:148) at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:820) at org.hibernate.metamodel.source.internal.SessionFactoryBuilderImpl.buildSessionFactory(SessionFactoryBuilderImpl.java:65) at org.hibernate.metamodel.source.internal.MetadataImpl.buildSessionFactory(MetadataImpl.java:340) I have tried adding some other annotations, but shouldn't the defaults work and create the tables and foreign key? If I remove the department from User, tables get generated fine. Thanks in advance!

  • Problem when copying array of different types using Arrays.copyOf

    - by Shervin
    I am trying to create a method that pretty much takes anything as a parameter, and returns a concatenated string representation of the value with some delimiter. public static String getConcatenated(char delim, Object ...names) { String[] stringArray = Arrays.copyOf(names, names.length, String[].class); //Exception here return getConcatenated(delim, stringArray); } And the actual method public static String getConcatenated(char delim, String ... names) { if(names == null || names.length == 0) return ""; StringBuilder sb = new StringBuilder(); for(int i = 0; i < names.length; i++) { String n = names[i]; if(n != null) { sb.append(n.trim()); sb.append(delim); } } //Remove the last delim return sb.substring(0, sb.length()-1).toString(); } And I have the following JUnit test: final String two = RedpillLinproUtils.getConcatenated(' ', "Shervin", "Asgari"); Assert.assertEquals("Result", "Shervin Asgari", two); //OK final String three = RedpillLinproUtils.getConcatenated(';', "Shervin", "Asgari"); Assert.assertEquals("Result", "Shervin;Asgari", three); //OK final String four = RedpillLinproUtils.getConcatenated(';', "Shervin", null, "Asgari", null); Assert.assertEquals("Result", "Shervin;Asgari", four); //OK final String five = RedpillLinproUtils.getConcatenated('/', 1, 2, null, 3, 4); Assert.assertEquals("Result", "1/2/3/4", five); //FAIL However, the test fails on the last part with the exception: java.lang.ArrayStoreException at java.lang.System.arraycopy(Native Method) at java.util.Arrays.copyOf(Arrays.java:2763) Can someone spot the error?

  • activemerchant PayPalExpress transaction is invalid

    - by Ameya Savale
    I am trying to integrate activemerchant into my ruby on rails application. This is my controller where I get the purchase attirbutes and create a PaypalExpressResponse object def checkout total_as_cents, purchase_params = get_setup_params(Schedule.find(params[:schedule]), request) setup_response = @gateway.setup_purchase(total_as_cents, purchase_params) redirect_to @gateway.redirect_url_for(setup_response.token) end @gateway is my PaypalExpressGateway object which I create using this method in my controller def assign_gateway @gateway = PaypalExpressGateway.new( :login => api_user, :password => api_pass, :signature => api_signature ) end I got the api_user, api_pass, and api_signature values from my developer.paypal.com account, when I logged in for the first time there was already a sandbox user created as a merchant which is where I got the api credentials from. And finally here is my get_setup_params method: def get_setup_params(schedule, request) purchase_params = { :ip => request.remote_ip, :return_url => url_for(:action => 'review', :only_path => false, :sched => schedule.id), :cancel_return_url => register_path, :allow_note => true, :item => schedule.id } return to_cents(schedule.fee), purchase_params end How ever when I click on the checkout button, I get redirected to a sandbox paypal page saying "This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow." I'm not sure exactly what's wrong, I think the problem lies in the credentials but don't know why. Any help will be appreciated. One other point, I'm running this in my development environment so I have put this in my config file config.after_initialize do ActiveMerchant::Billing::Base.mode = :test end UPDATE Found out what the problem was, my return cancel url was invalid instead of using register_path, I used url_for(action: "action-name", :only_path => false) this answer helped me Rails ActiveMerchant - Paypal Express Checkout Error even though I wasn't able to see the output of the response like the person has managed to do

  • Hibernate HQL and Grails- How do I compare collections?

    - by BurtP
    Hi everyone (my first post!), I have an HQL question (in Groovy/Grails) I was hoping someone could help me with. I have a simple Asset object with a one-to-many Tags collection. class Asset { Set tags static hasMany = [tags:Tag] } class Tag { String name } What I'm trying to do in HQL: A user passes in some tags in params.tags (ex: groovy grails rocks) and wants to return Asset(s) that have those tags, and only those exact tags. Here's my HQL that returns Assets if one or more of the tags are present in an Assets tags: SELECT DISTINCT a FROM Asset a LEFT JOIN a.tags t WHERE t IN (:tags) assetList = Asset.executeQuery( hql, [tags:tokenizedTagListFromParams] The above code works perfect, but its really like an OR. If any of the tag(s) are found, it will return that Asset. I only want to return Assets that have those exact same tags (in number as well). Every time a new tag is created, I new Tag(name:xxx).save() so I can get the Tag instances and unique ID's for each tag that was asked for. I also tried converting the passed in tags to a list of Tag instances with Tag.findByName(t1) for each tag, and also a list of (unique) Tag Id's into the HQL above with no luck. I would appreciate any help/advice. Thank you for your time, Burt

  • How can I set QNetworkReply properties to get correct NCBI pages?

    - by Claire Huang
    I try to get this following url using the downloadURL function: http://www.ncbi.nlm.nih.gov/nuccore/27884304 But the data is not as what we can see through the browser. Now I know it's because that I need to give the correct information such as browser, how can I know what kind of information I need to set, and how can I set it? (By setHeader function??) In VC++, we can use CInternetSession and CHttpConnection Object to get the correct information without setting any other detail information, is there any similar way in Qt or other cross-platform C++ network lib?? (Yes, I need the the cross-platform property.) QNetworkReply::NetworkError downloadURL(const QUrl &url, QByteArray &data) { QNetworkAccessManager manager; QNetworkRequest request(url); request.setHeader(QNetworkRequest::ContentTypeHeader ,"Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7 (.NET CLR 3.5.30729)"); QNetworkReply *reply = manager.get(request); QEventLoop loop; QObject::connect(reply, SIGNAL(finished()), &loop, SLOT(quit())); loop.exec(); int direction; QVariant statusCodeV = reply->attribute(QNetworkRequest::RedirectionTargetAttribute); QUrl redirectTo = statusCodeV.toUrl(); if (!redirectTo.isEmpty()) { if (redirectTo.host().isEmpty()) { const QByteArray newaddr = ("http://"+url.host()+redirectTo.encodedPath()).toAscii(); redirectTo.setEncodedUrl(newaddr); redirectTo.setHost(url.host()); } return (downloadURL(redirectTo, data)); } if (reply->error() != QNetworkReply::NoError) { return reply->error(); } data = reply->readAll(); delete reply; return QNetworkReply::NoError; }

  • Finding the left-most and right-most points of a list. std::find_if the right way to go?

    - by Tom
    Hi, I have a list of Point objects, (each one with x,y properties) and would like to find the left-most and right-most points. I've been trying to do it with find_if, but i'm not sure its the way to go, because i can't seem to pass a comparator instance. Is find_if the way to go? Seems not. So, is there an algorithm in <algorithm> to achieve this? Thanks in advance. #include <iostream> #include <list> #include <algorithm> using namespace std; typedef struct Point{ float x; float y; } Point; bool left(Point& p1,Point& p2) { return p1.x < p2.x; } int main(){ Point p1 ={-1,0}; Point p2 ={1,0}; Point p3 ={5,0}; Point p4 ={7,0}; list <Point> points; points.push_back(p1); points.push_back(p2); points.push_back(p3); points.push_back(p4); //Should return an interator to p1. find_if(points.begin(),points.end(),left); return 0; }

  • Python Ephem / Datetime calculation

    - by dassouki
    the output should process the first date as "day" and second as "night". I've been playing with this for a few hours now and can't figure out what I'm doing wrong. Any ideas? Edit I assume that the problem is due to my date comparison implementation Output: $ python time_of_day.py * should be day: event date: 2010/4/6 16:00:59 prev rising: 2010/4/6 09:24:24 prev setting: 2010/4/5 23:33:03 next rise: 2010/4/7 09:22:27 next set: 2010/4/6 23:34:27 day * should be night: event date: 2010/4/6 00:01:00 prev rising: 2010/4/5 09:26:22 prev setting: 2010/4/5 23:33:03 next rise: 2010/4/6 09:24:24 next set: 2010/4/6 23:34:27 day time_of_day.py import datetime import ephem # install from http://pypi.python.org/pypi/pyephem/ #event_time is just a date time corresponding to an sql timestamp def type_of_light(latitude, longitude, event_time, utc_time, horizon): o = ephem.Observer() o.lat, o.long, o.date, o.horizon = latitude, longitude, event_time, horizon print "event date ", o.date print "prev rising: ", o.previous_rising(ephem.Sun()) print "prev setting: ", o.previous_setting(ephem.Sun()) print "next rise: ", o.next_rising(ephem.Sun()) print "next set: ", o.next_setting(ephem.Sun()) if o.previous_rising(ephem.Sun()) <= o.date <= o.next_setting(ephem.Sun()): return "day" elif o.previous_setting(ephem.Sun()) <= o.date <= o.next_rising(ephem.Sun()): return "night" else: return "error" print "should be day: ", type_of_light('45.959','-66.6405','2010/4/6 16:01','-4', '-6') print "should be night: ", type_of_light('45.959','-66.6405','2010/4/6 00:01','-4', '-6')

  • VSTO Word ContentControls, Y U No have Name property?

    - by System.Cats.Lol
    When you add a VSTO (not Word native) content control, you specify the name: controls.AddContentControl(wordRange, "foo", wdType); Where controls is the VSTO (extended) Document.Controls collection. You can later look up the control by name: ContentControl myContentControl = controls["foo"]; So why in the world is there no Name property for ContentControl? (or ContentControlBase, or any of the other derivatives). I'm implementing a wrapper class for the Document.Controls property that lets you add or iterate the content controls. When iterating the underlying Document.Controls, there's no way to look up the name of each control. (We need it to return an instance of our ContentControl wrapper). So currently I'm doing this in our ContentControls wrapper class: public IEnumerator<IContentControl> GetEnumerator() { System.Collections.IEnumerator en = this.wordControls.GetEnumerator(); while (en.MoveNext()) { // VSTO Document.Controls includes all managed controls, not just // VSTO ContentControls; return only those. if (en.Current is Microsoft.Office.Tools.Word.ContentControl) { // The control's name isn't stored with the control, only when it was added, // so use a placeholder name for the wrapper. yield return new ContentControl("Unknown", (Microsoft.Office.Tools.Word.ContentControl)en.Current); } } } I'd prefer to not have to resort to keeping a map of names-to-wrapper-objects in our ContentControls object. Can anyone tell me how to get the control's name (the name parameter that was passed to Controls.Add()?

  • C# parameters by reference and .net garbage collection

    - by Yarko
    I have been trying to figure out the intricacies of the .NET garbage collection system and I have a question related to C# reference parameters. If I understand correctly, variables defined in a method are stored on the stack and are not affected by garbage collection. So, in this example: public class Test { public Test() { } public int DoIt() { int t = 7; Increment(ref t); return t; } private int Increment(ref int p) { p++; } } the return value of DoIt() will be 8. Since the location of t is on the stack, then that memory cannot be garbage collected or compacted and the reference variable in Increment() will always point to the proper contents of t. However, suppose we have: public class Test { private int t = 7; public Test() { } public int DoIt() { Increment(ref t); return t; } private int Increment(ref int p) { p++; } } Now, t is stored on the heap as it is a value of a specific instance of my class. Isn't this possibly a problem if I pass this value as a reference parameter? If I pass t as a reference parameter, p will point to the current location of t. However, if the garbage collector moves this object during a compact, won't that mess up the reference to t in Increment()? Or does the garbage collector update even references created by passing reference parameters? Do I have to worry about this at all? The only mention of worrying about memory being compacted on MSDN (that I can find) is in relation to passing managed references to unmanaged code. Hopefully that's because I don't have to worry about any managed references in managed code. :)
