  • Getting each loaded image

    - by Hwang
    The images only loads into the last MC, how to make it load into each MC? private function imageHandler():void { imageBox=new MovieClip(); imageBox.graphics.lineStyle(5, 0xFFFFFF); imageBox.graphics.beginFill(0xFF0000); imageBox.graphics.drawRect(0,0,150,225); imageBox.graphics.endFill(); allImage.addChild(imageBox); } private function getPhoto():void { for (i=0; i<myXMLList.length(); i++) { placePhoto(); imageHandler(); imagesArray.push(imageBox); imagesArray[i].x=20+(200*i); } addChild(allImage); allImage.x=-(allImage.width+20); allImage.y=-(allImage.height+50); } private function placePhoto():void { loadedPic=myXMLList[i].@PIC; galleryLoader = new Loader(); galleryLoader.load(new URLRequest(loadedPic)); galleryLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,picLoaded); } private function picLoaded(event:Event):void { var bmpD=event.target.content.bitmapData for (j; j<myXMLList.length(); j++) { bmp=new Bitmap(bmpD); bmp.smoothing=true; bmp.name="bmp"+j; imagesArray[j].addChild(bmp); } }

  • JAXB does not call setter when unmarshalling objects

    - by Yaneeve
    Hi all, I am using JAXB 2.0 JDK 6 in order to unmarshall an XML instance into POJOs. In order to add some custom validation I have inserted a validation call into the setter of a property, yet despite it being private, it seems that the unmarshaller does not call the setter but directly modifies the private field. It is crucial to me that the custom validation occurs for this specific field every unmarshall call. What should I do? Code: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "LegalParams", propOrder = { "value" }) public class LegalParams { private static final Logger LOG = Logger.getLogger(LegalParams.class); @XmlTransient private LegalParamsValidator legalParamValidator; public LegalParams() { try { WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext(); LegalParamsFactory legalParamsFactory = (LegalParamsFactory) webApplicationContext.getBean("legalParamsFactory"); HttpSession httpSession = SessionHolder.getInstance().get(); legalParamValidator = legalParamsFactory.newLegalParamsValidator(httpSession); } catch (LegalParamsException lpe) { LOG.warn("Validator related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", lpe); } catch (Exception e) { LOG.warn("Spring related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", e); } } @XmlValue private String value; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * @throws TestCaseValidationException * */ public void setValue(String value) throws TestCaseValidationException { legalParamValidator.assertValid(value); this.value = value; } }

  • Matlab and .net problem with character string function input

    - by Peter
    I have a MATLAB function that I've compiled into a .net library. The function is a simple one that takes a character array as an input and a numeric array as output: function insert = money(dateLimit) .. insert = [1 2]; The function works fine when no function arguments are specified (a default argument is provided inside the function) Dim sf As New SpreadFinder.SpreadFinder Dim output = sf.money() As soon as an argument is specified .net complains. I'm thinking this should be easy and has been done before but searching through MATLAB documentation doesn't offer much help. Here's what I've tried. The sf.money() overload for the function with arguments is (numArgsOut as Integer, argsOut as MWArray, argsIn as MWArray) and hence that's what I've tried. What am I missing? Dim sf As New SpreadFinder.SpreadFinder Dim inputArgs(1) As Arrays.MWCharArray Dim dateLimitString As String = "some string" inputArgs(0) = New Arrays.MWCharArray(dateLimitString) Dim outputArgs(1) As Arrays.MWNumericArray outputArgs(0) = New Arrays.MWNumericArray() sf.money(1, outputArgs, inputArgs) Gives System.NullReferenceException : Object reference not set to an instance of an object. at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, Int32 numArgsIn, MWArray[] argsIn) at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn) at SpreadFinder.SpreadFinder.money(Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn)

  • Types issue in F#

    - by Andry
    Hello! In my ongoing adventure deep diving into f# I am understanding a lot of this powerful language but there are things that I still do not understand so clearly. One of the most important issues I need to master is types. Well the book I am reading is very straight forward and introduces entities and main functionalities with a direct approach. The first thing I could get start with is types. It introduces the main types as list, option, tuples, and so on... It is clearly underlined that all these types are IMMUTABLE for many reasons regarding functional programming and data consistance in functional programing. Well, no problems until now... But now I am getting started with Concrete Types... Well... I have problems in managing with types like list, option, tuples, types created through new operator and concrete types created using type keyword (for abbreviations, concrete types...). So my question is: how can I efficently catalogue/distinguish all types of data in f#???? I can create a perfect separation among types in C#, VB.NET... FOr example in VB.NET there are value and reference types while in C# there are only references and also int, double are treated as objects (they are objects while in VB.NET a value type is not a object and there is a split in types for this reason). Well in F# I cannot create such differences among types in the language. Can you help me? I hope I was clear.

  • Java: Cipher package (encrypt and decrypt). invalid key error

    - by noinflection
    Hello folks, i am doing a class with static methods to encrypt and decrypt a message using javax.crypto. I have 2 static methods that use ecipher and dcipher in order to do what they are supossed to do i need to initialize some variables (which are static also). But when i try to use it i get InvalidKeyException with the parameters i give to ecipher.init(...). I can't find why. Here is the code: private static byte[] raw = {-31, 17, 7, -34, 59, -61, -60, -16, 26, 87, -35, 114, 0, -53, 99, -116, -82, -122, 68, 47, -3, -17, -21, -82, -50, 126, 119, -106, -119, -5, 109, 98}; private static SecretKeySpec skeySpec; private static Cipher ecipher; private static Cipher dcipher; static { try { skeySpec = new SecretKeySpec(raw, "AES"); // Instantiate the cipher ecipher = Cipher.getInstance("AES"); dcipher = Cipher.getInstance("AES"); ecipher.init(Cipher.ENCRYPT_MODE, skeySpec); dcipher.init(Cipher.DECRYPT_MODE, skeySpec); } catch (NoSuchAlgorithmException e) { throw new UnhandledException("No existe el algoritmo deseado", e); } catch (NoSuchPaddingException e) { throw new UnhandledException("No existe el padding deseado", e); } catch (InvalidKeyException e) { throw new UnhandledException("Clave invalida", e); } }

  • purpose of 3rd party mvc ?

    - by Honey
    ive seen many third party mvcs or frameworks such as codeignitor , cakephp, and so on. what i want to know is what are their purposes? ive created my own framework call it an mvc or framework (in my opinion their all the same). in my framework i have all the classes in one folder called classes and all functions in another. its all organized and when a new project comes in i am able to complete it fast. i have looked at the applications that i mentioned and it seems to have huge articles and tutorials to study. what is the purpose? why not study the main language such as php, javascript/ajax or jquery, and so on then build something that you know the ins and outs of so that any project comes your way you know what to do. ive known some people who use cakephp and for every project they get stuck and need to figure out what to do. another guy i knew worked with joomla and every basic company website that came his way he would reverse engineer joomla to make it work with the site. are people using these applications because they lack knowledge in the languages? or sometimes have no choice but to make a site while lacking language and put something together.

  • Entity Framework - Foreign key constraints not added for inherited entity

    - by Tri Q
    Hello, It appears to me that a strange phenomenon is occurring with inherited entities (TPT) in EF4. I have three entities. 1. Asset 2. Property 3. Activity Property is a derived-type of Asset. Property has many activities (many-to-many) When modeling this in my EDMX, everything seems fine until I try to insert a new Property into the database. If the property does not contain any Activity, it works, but all hell breaks loose when I add some new activities to the new Property. As it turns out after 2 days of crawling the web and fiddling around, I noticed that in the EF store (SSDL) some of the constraints between entities were not picked up during the update process. Property_Activity table which links properties and activities show only one constraint FK_Property_Activity_Activity but FK_Property_Activity_Property was missing. I knew this is an Entity Framework anomoly because when I switched the relationship in the database to: Asset <-- Asset_Activity <-- Activity After an update, all foreign key constraints are picked up and the save is successful, with or without activities in the new property. Is this intended or a bug in EF? How do I get around this problem? Should I abandon inheritance altogether?

  • Is this OleDbDataAdapter bug

    - by ????
    It doesn't look to me OleDbDataAdapter should throw an exception on trying to fill DataSet for a db table column of type decimal(28,3). The message is "The numerical value is too large to fit into a 96 bit decimal". Could you just check this, I have no significant experience with ADO.NET and OLE DB components? The VB.NET code we have in the application is this: Dim dbDataSet As New DataSet Dim dbDataAdapter As OleDbDataAdapter Dim dbCommand As OleDbCommand Dim conn As OleDbConnection Dim connectionString As String 'parts where connectionString is set conn = New OleDbConnection(connectionString) 'part where sqlQuery is set but it ends up being "SELECT Price As 'Price' From PricebookView" - Price is of type decimal(28,3) dbCommand = New OleDbCommand(sqlQuery, conn) dbCommand.CommandTimeout = cmdTimeout dbDataAdapter = New OleDbDataAdapter(dbCommand) dbDataAdapter.Fill(dbDataSet) The last line is where the exception is thrown and the top of the stack trace is: at System.Data.ProviderBase.DbBuffer.ReadNumeric(Int32 offset) at System.Data.OleDb.ColumnBinding.Value_NUMERIC() at System.Data.OleDb.ColumnBinding.Value() at System.Data.OleDb.OleDbDataReader.GetValues(Object[] values) at System.Data.ProviderBase.DataReaderContainer.CommonLanguageSubsetDataReader.GetValues(Object[] values) at System.Data.ProviderBase.SchemaMapping.LoadDataRow() at System.Data.Common.DataAdapter.FillLoadDataRow(SchemaMapping mapping) at System.Data.Common.DataAdapter.FillFromReader(DataSet dataset, DataTable datatable, String srcTable, DataReaderContainer dataReader, Int32 startRecord, Int32 maxRecords, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DataAdapter.Fill(DataSet dataSet, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords) at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet) ... I am not sure why does it try to set the value to Int32. Thank you for the time !

  • What permissions do I need to grant to run RavenDB in Server mode?

    - by dalesmithtx
    I'm reading through Rob Ashton's excellent blog post on RavenDB: http://codeofrob.com/archive/2010/05/09/ravendb-an-introduction.aspx and I'm working through the code as I read. But when I try to add an index, I get a 401 error. Here's the code: class Program { static void Main(string[] args) { using (var documentStore = new DocumentStore() { Url = "http://localhost:8080" }) { documentStore.Initialise(); documentStore.DatabaseCommands.PutIndex( "BasicEntityBySomeData", new IndexDefinition<BasicEntity, BasicEntity>() { Map = docs => from doc in docs where doc.SomeData != null select new { SomeData = doc.SomeData }, }); string entityId; using (var documentSession = documentStore.OpenSession()) { var entity = new BasicEntity() { SomeData = "Hello, World!", SomeOtherData = "This is just another property", }; documentSession.Store(entity); documentSession.SaveChanges(); entityId = entity.Id; var loadedEntity = documentSession.Load<BasicEntity>(entityId); Console.WriteLine(loadedEntity.SomeData); var docs = documentSession.Query<BasicEntity>("BasicEntityBySomeData") .Where("SomeData:Hello~") .WaitForNonStaleResults() .ToArray(); docs.ToList().ForEach(doc => Console.WriteLine(doc.SomeData)); Console.Read(); } } } It throws the 401 error when on the line that makes the PutIndex() call. Any ideas what permissions I need to apply? And where I need to apply them?

  • ASP.NET OleDbConnection Problem

    - by Matt
    I'm working on an ASP.NET website where I am using an asp:repeater with paging done through a VB.NET code-behind file. I'm having trouble with the database connection though. As far as I can tell, the paging is working, but I can't get the data to be certain. The database is a Microsoft Access database. The function that should be accessing the database is: Dim pagedData As New PagedDataSource Sub Page_Load(ByVal obj As Object, ByVal e As EventArgs) doPaging() End Sub Function getTheData() As DataTable Dim DS As New DataSet() Dim strConnect As New OleDbConnection("Provider = Microsoft.Jet.OLEDB.4.0;Data Source=App_Data/ArtDatabase.mdb") Dim objOleDBAdapter As New OleDbDataAdapter("SELECT ArtID, FileLocation, Title, UserName, ArtDate FROM Art ORDER BY Art.ArtDate DESC", strConnect) objOleDBAdapter.Fill(DS, "Art") Return DS.Tables("Art").Copy End Function Sub doPaging() pagedData.DataSource = getTheData().DefaultView pagedData.AllowPaging = True pagedData.PageSize = 2 Try pagedData.CurrentPageIndex = Int32.Parse(Request.QueryString("Page")).ToString() Catch ex As Exception pagedData.CurrentPageIndex = 0 End Try btnPrev.Visible = (Not pagedData.IsFirstPage) btnNext.Visible = (Not pagedData.IsLastPage) pageNumber.Text = (pagedData.CurrentPageIndex + 1) & " of " & pagedData.PageCount ArtRepeater.DataSource = pagedData ArtRepeater.DataBind() End Sub The ASP.NET is: <asp:Repeater ID="ArtRepeater" runat="server"> <HeaderTemplate> <h2>Items in Selected Category:</h2> </HeaderTemplate> <ItemTemplate> <li> <asp:HyperLink runat="server" ID="HyperLink" NavigateUrl='<%# Eval("ArtID", "ArtPiece.aspx?ArtID={0}") %>'> <img src="<%# Eval("FileLocation") %>" alt="<%# DataBinder.Eval(Container.DataItem, "Title") %>t"/> <br /> <%# DataBinder.Eval(Container.DataItem, "Title") %> </asp:HyperLink> </li> </ItemTemplate> </asp:Repeater>

  • Scala Interpreter scala.tools.nsc.interpreter.IMain Memory leak

    - by Peter
    I need to write a program using the scala interpreter to run scala code on the fly. The interpreter must be able to run an infinite amount of code without being restarted. I know that each time the method interpret() of the class scala.tools.nsc.interpreter.IMain is called, the request is stored, so the memory usage will keep going up forever. Here is the idea of what I would like to do: var interpreter = new IMain while (true) { interpreter.interpret(some code to be run on the fly) } If the method interpret() stores the request each time, is there a way to clear the buffer of stored requests? What I am trying to do now is to count the number of times the method interpret() is called then get a new instance of IMain when the number of times reaches 100, for instance. Here is my code: var interpreter = new IMain var counter = 0 while (true) { interpreter.interpret(some code to be run on the fly) counter = counter + 1 if (counter > 100) { interpreter = new IMain counter = 0 } } However, I still see that the memory usage is going up forever. It seems that the IMain instances are not garbage-collected by the JVM. Could somebody help me solve this issue? I really need to be able to keep my program running for a long time without restarting, but I cannot afford such a memory usage just for the scala interpreter. Thanks in advance, Pet

  • Learning Hibernate: too many connections

    - by stivlo
    I'm trying to learn Hibernate and I wrote the simplest Person Entity and I was trying to insert 2000 of them. I know I'm using deprecated methods, I will try to figure out what are the new ones later. First, here is the class Person: @Entity public class Person { private int id; private String name; @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "person") @TableGenerator(name = "person", table = "sequences", allocationSize = 1) public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } } Then I wrote a small App class that insert 2000 entities with a loop: public class App { private static AnnotationConfiguration config; public static void insertPerson() { SessionFactory factory = config.buildSessionFactory(); Session session = factory.getCurrentSession(); session.beginTransaction(); Person aPerson = new Person(); aPerson.setName("John"); session.save(aPerson); session.getTransaction().commit(); } public static void main(String[] args) { config = new AnnotationConfiguration(); config.addAnnotatedClass(Person.class); config.configure("hibernate.cfg.xml"); //is the default already new SchemaExport(config).create(true, true); //print and execute for (int i = 0; i < 2000; i++) { insertPerson(); } } } What I get after a while is: Exception in thread "main" org.hibernate.exception.JDBCConnectionException: Cannot open connection Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Too many connections Now I know that probably if I put the transaction outside the loop it would work, but mine was a test to see what happens when executing multiple transactions. And since there is only one open at each time, it should work. I tried to add session.close() after the commit, but I got Exception in thread "main" org.hibernate.SessionException: Session was already closed So how to solve the problem?

How to do that?

  • Quick help refactoring Ruby Class

    - by mplacona
    I've written this class that returns feed updates, but am thinking it can be further improved. It's not glitchy or anything, but as a new ruby developer, I reckon it's always good to improve :-) class FeedManager attr_accessor :feed_object, :update, :new_entries require 'feedtosis' def initialize(feed_url) @feed_object = Feedtosis::Client.new(feed_url) fetch end def fetch @feed_object.fetch end def update @updates = fetch end def updated? @updates.new_entries.count > 0 ? true : false end def new_entries @updates.new_entries end end As you can see, it's quite simple, but the things I'm seeing that aren't quite right are: Whenever I call fetch via terminal, it prints a list with the updates, when it's really supposed return an object. So as an example, in the terminal if I do something like: client = Feedtosis::Client.new('http://stackoverflow.com/feeds') result = client.fetch I then get: <Curl::Easy http://stackoverflow.com/feeds> Which is exactly what I'd expect. However, when doing the same thing with "inniting" class with: FeedManager.new("http://stackoverflow.com/feeds") I'm getting the object returning as an array with all the items on the feed. Sure I'm doing something wrong, so any help refactoring this class will he greatly appreciated. Also, I'd like to see comments about my implementation, as well as any sort of comment to make it better would be welcome. Thanks in advance

  • CascadingDropDown taking two parameters...

    - by WeeShian
    I have a page with 3 dropdownlist, 2nd and 3rd dropdownlist are added with CascadingDropDown. 3rd dropdownlist will take parameters from 1st and 2nd dropdownlist. So, in current example for CascadingDropDown i have found from google, they are only passing one parameter to the WebService method. How can pass two parameters to the service method, so that my 3rd dropdownlist will based on the SelectedValue of 1st and 2nd dropdownlist? <WebMethod()> _ Public Function GetTeams(ByVal knownCategoryValues As String, ByVal category As String) As CascadingDropDownNameValue() Dim strConnection As String = ConfigurationManager.ConnectionStrings("nerdlinessConnection").ConnectionString Dim sqlConn As SqlConnection = New SqlConnection(strConnection) Dim strTeamQuery As String = "SELECT * FROM TEAM WHERE conf_id = @confid" Dim cmdFetchTeam As SqlCommand = New SqlCommand(strTeamQuery, sqlConn) Dim dtrTeam As SqlDataReader Dim kvTeam As StringDictionary = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues) Dim intConfId As Integer If Not kvTeam.ContainsKey("Conference") Or Not Int32.TryParse(kvTeam("Conference"), intConfId) Then Return Nothing End If cmdFetchTeam.Parameters.AddWithValue("@confid", intConfId) Dim myTeams As New List(Of CascadingDropDownNameValue) sqlConn.Open() dtrTeam = cmdFetchTeam.ExecuteReader While dtrTeam.Read() Dim strTeamName As String = dtrTeam("team_name").ToString Dim strTeamId As String = dtrTeam("team_id").ToString myTeams.Add(New CascadingDropDownNameValue(strTeamName, strTeamId)) End While Return myTeams.ToArray End Function This is the sample code i found! As you can see in the code, '@confid' will be passed from 2nd dropdownlist! So, hw do i modify this code to get the selected value from 1st dropdownlist as well??

I tried to use the next code in my managed bean: public void run() { try { URL url = new URL(this.filename); URLConnection connection = url.openConnection(); bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream())); if (bufferedReader == null) { return; } System.out.println("wwwwwwwwwwwwwwwwwwwww"); String str = bufferedReader.readLine(); System.out.println("qqqqqqqqqqqqqqqqqqqqqqq = " + str); while (bufferedReader.readLine() != null) { System.out.println("---- " + bufferedReader.readLine()); } } catch(MalformedURLException mue) { System.out.println("MalformedURLException in run() method"); mue.printStackTrace(); } catch(IOException ioe) { System.out.println("IOException in run() method"); ioe.printStackTrace(); } finally { try { bufferedReader.close(); } catch(IOException ioe) { System.out.println("UOException wile closing BufferedReader"); ioe.printStackTrace(); } } } public String doFileUpdate() { String str = FacesContext.getCurrentInstance().getExternalContext().getRequestServletPath(); System.out.println("111111111111111111111 str = " + str); str = "http://narod.ru/disk/20957166000/test.txt.html";//"http://localhost:8080/sfront/files/test.html"; System.out.println("222222222222222222222 str = " + str); FileUpdater fileUpdater = new FileUpdater(str); fileUpdater.run(); return null; } But the BufferedReader returns the html code of the current page, where i am trying to call managed bean's method. It's very strange thing - I have googled and none have had this problem. Maybe I do something wrong, maybe there us a simplest way to load file into web (jsf) app not using net API. Any ideas? Thanks very much for help! With best wishes)

  • Windows Azure ASP.NET MVC Role behaves strangely when redirecting from HTTP to HTTPS

    - by Rinat Abdullin
    Subj. I've got an ASP.NET 2 MVC Worker Role Application, that does not differ much from the default template. When attempting redirect from HTTP to HTTPS (this happens when we access constroller secured by the usual RequireSSL attribute implementation) we get blank page with "Bad Request" message. IntelliTrace shows this: Thrown: "The file '/Views/Home/LogOnUserControl.aspx' does not exist." (System.Web.HttpException) Call stack is really short: [External Code] App_Web_vfahw7gz.dll!ASP.views_shared_site_master.__Render__control1(System.Web.UI.HtmlTextWriter __w = {unknown}, System.Web.UI.Control parameterContainer = {unknown}) [External Code] App_Web_bsbqxr44.dll!ASP.views_home_index_aspx.ProcessRequest(System.Web.HttpContext context = {unknown}) [External Code] User control reference is the usual one in /Views/Shared/Site.Master: <div id="logindisplay"> <% Html.RenderPartial("LogOnUserControl"); %> </div> And partial view LogOnUserControl.ashx is located in Views/Shared (and it is ASHX, not ASPX). Problem shows up, when we try to access site pages, that require auth and redirect. These pages are secured by RequireSSL attribute (Redirect == true): [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = false)] public sealed class RequireSslAttribute : FilterAttribute, IAuthorizationFilter { public bool Redirect { get; set; } // Methods public void OnAuthorization(AuthorizationContext filterContext) { // this get's messy, when we are running custom ports // within the local dev fabric. // hence we disable code in the debug #if !DEBUG if (filterContext == null) { throw new ArgumentNullException("filterContext"); } if (filterContext.HttpContext.Request.IsSecureConnection) return; var canRedirect = string.Equals(filterContext.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase); if (canRedirect && Redirect) { var builder = new UriBuilder { Scheme = "https", Host = filterContext.HttpContext.Request.Url.Host, Path = filterContext.HttpContext.Request.RawUrl }; filterContext.Result = new RedirectResult(builder.ToString()); } else { throw new HttpException(0x193, "Access forbidden. The requested resource requires an SSL connection."); } #endif } } Obviously we compile in RELEASE for this case. Does anybody have any idea, what could cause this strange exception and how to get rid of it?

  • Avoid the problem with BigDecimal when migrating to Java 1.4 to Java 1.5+

    - by romaintaz
    Hello, I've recently migrated a Java 1.4 application to a Java 6 environment. Unfortunately, I encountered a problem with the BigDecimal storage in a Oracle database. To summarize, when I try to store a "7.65E+7" BigDecimal value (76,500,000.00) in the database, Oracle stores in reality the value of 7,650,000.00. This defect is due to the rewritting of the BigDecimal class in Java 1.5 (see here). In my code, the BigDecimal was created from a double using this kind of code: BigDecimal myBD = new BigDecimal("" + someDoubleValue); someObject.setAmount(myBD); // Now let Hibernate persists my object in DB... In more than 99% of the cases, everything works fine. Except that in really few case, the bug mentioned above occurs. And that's quite annoying. If I change the previous code to avoid the use of the String constructor of BigDecimal, then I do not encounter the bug in my uses cases: BigDecimal myBD = new BigDecimal(someDoubleValue); someObject.setAmount(myBD); // Now let Hibernate persists my object in DB... However, how can I be sure that this solution is the correct way to handle the use of BigDecimal? So my question is to know how I have to manage my BigDecimal values to avoid this issue: Do not use the new BigDecimal(String) constructor and use directly the new BigDecimal(double)? Force Oracle to use toPlainString() instead of toString() method when dealing with BigDecimal (and in this case how to do that)? Any other solution? Environment information: Java 1.6.0_14 Hibernate 2.1.8 (yes, it is a quite old version) Oracle JDBC 9.0.2.0 and also tested with 10.2.0.3.0 Oracle database 10.2.0.3.0

  • Silverlight - How do I make each item in a list box be the same height?

    - by NotDan
    How can I make a silverlight listbox have all items be the same size and have them take up 100% of the listbox height. I.e. 1 item would be the height of the listbox, 2 items would each be 50% of the height of the list box, etc... Edit - Here is the code public class UniformPanel : Panel { protected override Size MeasureOverride(Size availableSize) { Size panelDesiredSize = new Size(); for (int i = 0; i < Children.Count; i++) { UIElement child = Children[i]; child.Measure(availableSize); var childDesiredSize = child.DesiredSize; panelDesiredSize.Height += childDesiredSize.Height; if (panelDesiredSize.Width < childDesiredSize.Width) { panelDesiredSize.Width = childDesiredSize.Width; } } return panelDesiredSize; } protected override Size ArrangeOverride(Size finalSize) { double height = finalSize.Height/Children.Count; for (int i = 0; i < Children.Count; i++) { UIElement child = Children[i]; Size size = new Size(finalSize.Width, height); child.Arrange(new Rect(new Point(0, i * height), size)); } return finalSize; // Returns the final Arranged size } }
