  • Accessing Content Page elements

    - by Abdel Olakara
    Hi all, I am facing a strange problem.. may be i am overlooking something and not able to find the silly issue. Need your help! I have a Master page and a Content Page: <form id="AccountForm" runat="server"> <div> <asp:ContentPlaceHolder ID="MenuHolder" runat="server"> </asp:ContentPlaceHolder> </div> <hr /> <div> <asp:ContentPlaceHolder ID="ContentHolder" runat="server"> </asp:ContentPlaceHolder> </div> And my content page has some form elements: <asp:Content ID="Content3" ContentPlaceHolderID="ContentHolder" runat="server"> First Name: <asp:TextBox ID="fName" runat="server"></asp:TextBox> <br /> Middle Name: <asp:TextBox ID="mName" runat="server"></asp:TextBox> <br /> Family Name: <asp:TextBox ID="lName" runat="server"></asp:TextBox> <br /> Birthday: <asp:TextBox ID="birthday" runat="server"></asp:TextBox> <br /> Mobile Phone: <asp:TextBox ID="mobile" runat="server"></asp:TextBox> <br /> Alternate Phone: <asp:TextBox ID="phone" runat="server"></asp:TextBox> <br /> I also have the code for submit button in the content page where i try to retrieve the values from the form elements and persist it into DB. Here is the SubmitButton_Click code: protected void SubmitButton_Click(object sender, EventArgs e) { log.Info("From Submit button: " + customerObject.first_name + " " + customerObject.family_name); if (fName != null) log.Info("First Name is not null"); log.Info("First Name:" + fName.Text); log.Info("Middle Name:" + mName.Text); log.Info("Family Name:" + fName.Text); log.Info("Mobile:" + mobile.Text); log.Info("Phone: " + phone.Text); log.Info("Address:" + bAddressL1.Text + bAddressL2.Text); Strangly.. i don't get any data that is filled into my text fields? Their objects are not null as well!! why is this behaviour happening? I am not trying to access elements in master page or other.. all the fields are in the content page.. only thing is there is no form element in the content page and the form element is in master page! Thanks in advance for your suggestions and answers. Abdel Raoof Olakara

  • How can I configure a Factory with the possible providers?

    - by Jonathas Costa
    I have three assemblies: "Framework.DataAccess", "Framework.DataAccess.NHibernateProvider" and "Company.DataAccess". Inside the assembly "Framework.DataAccess", I have my factory (with the wrong implementation of discovery): public class DaoFactory { private static readonly object locker = new object(); private static IWindsorContainer _daoContainer; protected static IWindsorContainer DaoContainer { get { if (_daoContainer == null) { lock (locker) { if (_daoContainer != null) return _daoContainer; _daoContainer = new WindsorContainer(new XmlInterpreter()); // THIS IS WRONG! THIS ASSEMBLY CANNOT KNOW ABOUT SPECIALIZATIONS! _daoContainer.Register( AllTypes.FromAssemblyNamed("Company.DataAccess") .BasedOn(typeof(IReadDao<>)).WithService.FromInterface(), AllTypes.FromAssemblyNamed("Framework.DataAccess.NHibernateProvider") .BasedOn(typeof(IReadDao<>)).WithService.Base()); } } return _daoContainer; } } public static T Create<T>() where T : IDao { return DaoContainer.Resolve<T>(); } } This assembly also defines the base interface for data access IReadDao: public interface IReadDao<T> { IEnumerable<T> GetAll(); } I want to keep this assembly generic and with no references. This is my base data access assembly. Then I have the NHibernate provider's assembly, which implements the above IReadDao using NHibernate's approach. This assembly references the "Framework.DataAccess" assembly. public class NHibernateDao<T> : IReadDao<T> { public NHibernateDao() { } public virtual IEnumerable<T> GetAll() { throw new NotImplementedException(); } } At last, I have the "Company.DataAccess" assembly, which can override the default implementation of NHibernate provider and references both previously seen assemblies. public interface IProductDao : IReadDao<Product> { Product GetByName(string name); } public class ProductDao : NHibernateDao<Product>, IProductDao { public override IEnumerable<Product> GetAll() { throw new NotImplementedException("new one!"); } public Product GetByName(string name) { throw new NotImplementedException(); } } I want to be able to write... IRead<Product> dao = DaoFactory.Create<IRead<Product>>(); ... and then get the ProductDao implementation. But I can't hold inside my base data access any reference to specific assemblies! My initial idea was to read that from a xml config file. So, my question is: How can I externally configure this factory to use a specific provider as my default implementation and my client implementation?

  • Java map / nio / NFS issue causing a VM fault: "a fault occurred in a recent unsafe memory access op

    - by Matthew Bloch
    I have written a parser class for a particular binary format (nfdump if anyone is interested) which uses java.nio's MappedByteBuffer to read through files of a few GB each. The binary format is just a series of headers and mostly fixed-size binary records, which are fed out to the called by calling nextRecord(), which pushes on the state machine, returning null when it's done. It performs well. It works on a development machine. On my production host, it can run for a few minutes or hours, but always seems to throw "java.lang.InternalError: a fault occurred in a recent unsafe memory access operation in compiled Java code", fingering one of the Map.getInt, getShort methods, i.e. a read operation in the map. The uncontroversial (?) code that sets up the map is this: /** Set up the map from the given filename and position */ protected void open() throws IOException { // Set up buffer, is this all the flexibility we'll need? channel = new FileInputStream(file).getChannel(); MappedByteBuffer map1 = channel.map(FileChannel.MapMode.READ_ONLY, 0, channel.size()); map1.load(); // we want the whole thing, plus seems to reduce frequency of crashes? map = map1; // assumes the host writing the files is little-endian (x86), ought to be configurable map.order(java.nio.ByteOrder.LITTLE_ENDIAN); map.position(position); } and then I use the various map.get* methods to read shorts, ints, longs and other sequences of bytes, before hitting the end of the file and closing the map. I've never seen the exception thrown on my development host. But the significant point of difference between my production host and development is that on the former, I am reading sequences of these files over NFS (probably 6-8TB eventually, still growing). On my dev machine, I have a smaller selection of these files locally (60GB), but when it blows up on the production host it's usually well before it gets to 60GB of data. Both machines are running java 1.6.0_20-b02, though the production host is running Debian/lenny, the dev host is Ubuntu/karmic. I'm not convinced that will make any difference. Both machines have 16GB RAM, and are running with the same java heap settings. I take the view that if there is a bug in my code, there is enough of a bug in the JVM not to throw me a proper exception! But I think it is just a particular JVM implementation bug due to interactions between NFS and mmap, possibly a recurrence of 6244515 which is officially fixed. I already tried adding in a "load" call to force the MappedByteBuffer to load its contents into RAM - this seemed to delay the error in the one test run I've done, but not prevent it. Or it could be coincidence that was the longest it had gone before crashing! If you've read this far and have done this kind of thing with java.nio before, what would your instinct be? Right now mine is to rewrite it without nio :)

  • Is my fragment usage correct, seems to be slow on adnroid

    - by Robertoq
    My app structure is that i have a menu with 5 menu-point om the left side, and the content on the right side.

  • Transaction on Entity FrameWork Refactoring and best performance how can i?

    - by programmerist
    i try to use transaction in Entity FrameWork. i have 3 tables Personel, Prim, Finans. in Prim table you look SatisTutari (int) if i add data in SatisTutari.Text instead of int value adding float value. Trannsaction must be run! Everything is ok but how can i refactoring or give best performance or best writing Transaction coding! i have 3 table so i have 3 entities: CREATE TABLE Personel (PersonelID integer PRIMARY KEY identity not null, Ad varchar(30), Soyad varchar(30), Meslek varchar(100), DogumTarihi datetime, DogumYeri nvarchar(100), PirimToplami float); Go create TABLE Prim (PrimID integer PRIMARY KEY identity not null, PersonelID integer Foreign KEY references Personel(PersonelID), SatisTutari int, Prim float, SatisTarihi Datetime); Go CREATE TABLE Finans (ID integer PRIMARY KEY identity not null, Tutar float); Personel, Prim,Finans my tables. if you look Prim table you can see Prim value float value if i write a textbox not float value my transaction must run. protected void btnSave_Click(object sender, EventArgs e) { using (TestEntities testCtx = new TestEntities()) { using (TransactionScope scope = new TransactionScope()) { Personel personel = new Personel(); Prim prim = new Prim(); Finans finans = new Finans(); //-----------------------------------------------------------------------Step 1 personel.Ad = txtName.Text; personel.Soyad = txtSurName.Text; personel.Meslek = txtMeslek.Text; personel.DogumTarihi = DateTime.Parse(txtSatisTarihi.Text); personel.DogumYeri = txtDogumYeri.Text; personel.PirimToplami = float.Parse(txtPrimToplami.Text); testCtx.AddToPersonel(personel); testCtx.SaveChanges(); //----------------------------------------------------------------------- step 2 prim.PersonelID = personel.PersonelID; prim.SatisTutari = int.Parse(txtSatisTutari.Text); prim.SatisTarihi = DateTime.Parse(txtSatisTarihi.Text); prim.Prim1 = double.Parse(txtPrim.Text); finans.Tutar = prim.SatisTutari * prim.Prim1; testCtx.AddToPrim(prim); testCtx.SaveChanges(); //----------------------------------------------------------------------- step 3 lblTutar.Text = finans.Tutar.Value.ToString(); testCtx.AddToFinans(finans); testCtx.SaveChanges(); scope.Complete(); } } How can i rearrange codes. i need best practice refactoring and best solution for reading easly and performance!!!

  • Why doesn't my form post when I disable the submit button to prevent double clicking?

    - by John MacIntyre
    Like every other web developer on the planet, I have an issue with users double clicking the submit button on my forms. My understanding is that the conventional way to handle this issue, is to disable the button immediately after the first click, however when I do this, it doesn't post. I did do some research on this, god knows there's enough information, but other questions like Disable button on form submission, disabling the button appears to work. The original poster of Disable button after submit appears to have had the same problem as me, but there is no mention on how/if he resolved it. Here's some code on how to repeat it (tested in IE8 Beta2, but had same problem in IE7) My aspx code <%@ Page Language="C#" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <script language="javascript" type="text/javascript"> function btn_onClick() { var chk = document.getElementById("chk"); if(chk.checked) { var btn = document.getElementById("btn"); btn.disabled = true; } } </script> <body> <form id="form1" runat="server"> <asp:Literal ID="lit" Text="--:--:--" runat="server" /> <br /> <asp:Button ID="btn" Text="Submit" runat="server" /> <br /> <input type="checkbox" id="chk" />Disable button on first click </form> </body> </html> My cs code using System; public partial class _Default : System.Web.UI.Page { protected override void OnInit(EventArgs e) { base.OnInit(e); btn.Click += new EventHandler(btn_Click); btn.OnClientClick = "btn_onClick();"; } void btn_Click(object sender, EventArgs e) { lit.Text = DateTime.Now.ToString("HH:mm:ss"); } } Notice that when you click the button, a postback occurs, and the time is updated. But when you check the check box, the next time you click the button, the button is disabled (as expected), but never does the postback. WHAT THE HECK AM I MISSING HERE??? Thanks in advance.

  • Is it ok to dynamic cast "this" as a return value?

    - by Panayiotis Karabassis
    This is more of a design question. I have a template class, and I want to add extra methods to it depending on the template type. To practice the DRY principle, I have come up with this pattern (definitions intentionally omitted): template <class T> class BaseVector: public boost::array<T, 3> { protected: BaseVector<T>(const T x, const T y, const T z); public: bool operator == (const Vector<T> &other) const; Vector<T> operator + (const Vector<T> &other) const; Vector<T> operator - (const Vector<T> &other) const; Vector<T> &operator += (const Vector<T> &other) { (*this)[0] += other[0]; (*this)[1] += other[1]; (*this)[2] += other[2]; return *dynamic_cast<Vector<T> * const>(this); } } template <class T> class Vector : public BaseVector<T> { public: Vector<T>(const T x, const T y, const T z) : BaseVector<T>(x, y, z) { } }; template <> class Vector<double> : public BaseVector<double> { public: Vector<double>(const double x, const double y, const double z); Vector<double>(const Vector<int> &other); double norm() const; }; I intend BaseVector to be nothing more than an implementation detail. This works, but I am concerned about operator+=. My question is: is the dynamic cast of the this pointer a code smell? Is there a better way to achieve what I am trying to do (avoid code duplication, and unnecessary casts in the user code)? Or am I safe since, the BaseVector constructor is private?

  • Performance tuning of a Hibernate+Spring+MySQL project operation that stores images uploaded by user

    - by Umar
    Hi I am working on a web project that is Spring+Hibernate+MySQL based. I am stuck at a point where I have to store images uploaded by a user into the database. Although I have written some code that works well for now, but I believe that things will mess up when the project would go live. Here's my domain class that carries the image bytes: @Entity public class Picture implements java.io.Serializable{ long id; byte[] data; ... // getters and setters } And here's my controller that saves the file on submit: public class PictureUploadFormController extends AbstractBaseFormController{ ... protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception{ MutlipartFile file; // getting MultipartFile from the command object ... // beginning hibernate transaction ... Picture p=new Picture(); p.setData(file.getBytes()); pictureDAO.makePersistent(p); // this method simply calls getSession().saveOrUpdate(p) // committing hiernate transaction ... } ... } Obviously a bad piece of code. Is there anyway I could use InputStream or Blob to save the data, instead of first loading all the bytes from the user into the memory and then pushing them into the database? I did some research on hibernate's support for Blob, and found this in Hibernate In Action book: java.sql.Blob and java.sql.Clob are the most efficient way to handle large objects in Java. Unfortunately, an instance of Blob or Clob is only useable until the JDBC transaction completes. So if your persistent class defines a property of java.sql.Clob or java.sql.Blob (not a good idea anyway), you’ll be restricted in how instances of the class may be used. In particular, you won’t be able to use instances of that class as detached objects. Furthermore, many JDBC drivers don’t feature working support for java.sql.Blob and java.sql.Clob. Therefore, it makes more sense to map large objects using the binary or text mapping type, assuming retrieval of the entire large object into memory isn’t a performance killer. Note you can find up-to-date design patterns and tips for large object usage on the Hibernate website, with tricks for particular platforms. Now apparently the Blob cannot be used, as it is not a good idea anyway, what else could be used to improve the performance? I couldn't find any up-to-date design pattern or any useful information on Hibernate website. So any help/recommendations from stackoverflowers will be much appreciated. Thanks

  • bottom uicomponent does not receive mouse events

    - by firemonkey
    HI, I am sure this is very basic, however I am not able to find the solution. I have a base ShapeContainer(UIComponent). I add a uicomponent which has mouse down listener to ShapeContainer. the listener works great. When I add a simple sprite(draw square) on the ShapeContainer, The listener does not work any more. In the code, if I comment below lines, The event listener works fine. var square:Sprite = new Sprite(); square.graphics.lineStyle(4,0x00FF00); square.graphics.drawRect(0,0,20,20); square.mouseEnabled=false; shapeContainer.addChildAt(square,1); I have tried few things like, mouseenabled=false on top sprite. also tried to add addChildAt but non of them did any help. How can I draw a shape and also have the event listener work. enter code here protected function application1_creationCompleteHandler(event:FlexEvent):void { var shapeContainer:UIComponent = new UIComponent(); shapeContainer.x=100; shapeContainer.y=100; shapeContainer.width=200; shapeContainer.height=200; rawChildren.addChild(shapeContainer); var EventListenerShape:UIComponent = new UIComponent(); EventListenerShape.x=100; EventListenerShape.y=100; EventListenerShape.width=200;a EventListenerShape.height=200; EventListenerShape.graphics.clear(); EventListenerShape.graphics.beginFill(0xf1f1f1, 0.1); EventListenerShape.graphics.drawRoundRect(0, 0, 200, 200, 10, 10); EventListenerShape.alpha = 0; EventListenerShape.graphics.endFill(); EventListenerShape.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownfunc); shapeContainer.addChild(EventListenerShape); var square:Sprite = new Sprite(); square.graphics.lineStyle(4,0x00FF00); square.graphics.drawRect(0,0,20,20); square.mouseEnabled=false; shapeContainer.addChildAt(square,1); } private function mouseDownfunc(e:MouseEvent){ trace("mouse Down **"); }    ]]> </mx:Script> <mx:Canvas id="uic" width="100%" height="100%" backgroundColor="0xFFFFFF"> </mx:Canvas>

Mappings: I have the following mapping for Installation: <?xml version="1.0" encoding="utf-8"?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="myProgram.Core" namespace="myProgram"> <class name="Installation" table="Installations" lazy="true"> <id name="Id" column="Id" type="int"> <generator class="native" /> </id> <property name="Name" column="Name" type="string" not-null="true" /> <property name="Description" column="Description" type="string" /> <bag name="ComputerSystems" inverse="true" lazy="true" cascade="all-delete-orphan"> <key column="InstallationId" /> <one-to-many class="ComputerSystem" /> </bag> </class> </hibernate-mapping> I have the following mapping for ComputerSystem: <?xml version="1.0" encoding="utf-8"?> <id name="Id" column="ID" type="int"> <generator class="native" /> </id> <property name="Name" column="Name" type="string" not-null="true" /> <property name="Description" column="Description" type="string" /> <many-to-one name="Installation" column="InstallationID" cascade="save-update" not-null="true" /> Classes: The Installation class is: public class Installation { public virtual String Description { get; set; } public virtual String Name { get; set; } public virtual IList<ComputerSystem> ComputerSystems { get { if (_computerSystemItems== null) { lock (this) { if (_computerSystemItems== null) _computerSystemItems= new List<ComputerSystem>(); } } return _computerSystemItems; } set { _computerSystemItems= value; } } protected IList<ComputerSystem> _computerSystemItems; public Installation() { Description = ""; Name= ""; } } The ComputerSystem class is: public class ComputerSystem { public virtual String Name { get; set; } public virtual String Description { get; set; } public virtual Installation Installation { get; set; } } The issue is that I get an error when trying to delete an installation that contains a ComputerSystem.

  • asp.net Multiple Page_Load events for a user control when using URL Routing

    - by Paul Hutson
    Hello, I've recently set up an ASP.net site (not using MVC.net) to use URL Routing (more on the code below) - when using user controls on the site (i.e I've created a "menu" user control to hold menu information) the page_load event for that control will fire twice when URLs have more than one variable passed over. i.e. pageName/VAR1 : will only fire the page_load event once. while pageName/VAR1/VAR2 : will fire the page_load event twice. *Multiple extra VARs added on the end will still only fire the page_load event twice*. Below are the code snippits from the files, the first is the MapPageRoute, located in the Global.asax : // Register a route for the Example page, with the NodeID and also the Test123 variables allowed. // This demonstrates how to have several items linked with the page routes. routes.MapPageRoute( "Multiple Data Example", // Route name "Example/{NodeID}/{test123}/{variable}", // Route URL - note the NodeID bit "~/Example.aspx", // Web page to handle route true, // Check for physical access new System.Web.Routing.RouteValueDictionary { { "NodeID", "1" }, // Default Node ID { "test123", "1" }, // Default addtional variable value { "variable", "hello"} // Default test variable value } ); Next is the way I've directed to the page in the menu item, this is a list item within a UL tag : <li class="TopMenu_ListItem"><a href="<%= Page.GetRouteUrl("Multiple Data Example", new System.Web.Routing.RouteValueDictionary { { "NodeID", "4855" }, { "test123", "2" } }) %>">Example 2</a></li> And finally the control that gets hit multiple times on a page load : // For use when the page loads. protected void Page_Load(object sender, EventArgs e) { // Handle the routing variables. // this handles the route data value for NodeID - if the page was reached using URL Routing. if (Page.RouteData.Values["NodeID"] != null) { nodeID = Page.RouteData.Values["NodeID"] as string; }; // this handles the route data value for Test123 - if the page was reached using URL Routing. if (Page.RouteData.Values["Test123"] != null) { ExampleOutput2.Text = "I am the output of the third variable : " + Page.RouteData.Values["Test123"] as string; }; // this handles the route data value for variable - if the page was reached using URL Routing. if (Page.RouteData.Values["variable"] != null) { ExampleOutput3.Text = "I say " + Page.RouteData.Values["variable"] as string; }; } Note, that when I'm just hitting the page and it uses the default values for items, the reloads do not happen. Any help or guidance that anyone can offer would be very much appreciated! EDIT : The User Control is only added to the page once. I've tested the load sequence by putting a breakpoint in the page_load event - it only hits twice when the extra routes are added. Thanks in Advance, Paul Hutson

  • How to access and work with XML from API in C#

    - by Jarek
    My goal is to pull XML data from the API and load it to a sql server database. The frist step I'm attempting here is to access the data and display it. Once I get this to work I'll loop through each row and insert the values into a sql server database. When I try to run the code below nothing happens and when I paste the url directly into the browser I get this error "2010-03-08 04:24:17 Wallet exhausted: retry after 2010-03-08 05:23:58. 2010-03-08 05:23:58" To me it seems that every iteration of the foreach loop makes a call to the site and I get blocked for an hour. Am I retrieving data from the API in an incorrect manner? Is there some way to load the data into memory or an array then loop through that? Here's the bit of code I hacked together. using System; using System.Data.SqlClient; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Xml; using System.Data; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { try { string userID = "123"; string apiKey = "abc456"; string characterID = "789"; string url = "http://api.eve-online.com/char/WalletTransactions.xml.aspx?userID=" + userID + "&apiKey=" + apiKey + "&characterID=" + characterID; XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(url); XmlNamespaceManager xnm1 = new XmlNamespaceManager(xmldoc.NameTable); XmlNodeList nList1 = xmldoc.SelectNodes("result/rowset/row", xnm1); foreach (XmlNode xNode in nList1) { Response.Write(xNode.InnerXml + "<br />"); } } catch (SqlException em) { Response.Write(em.Message); } } } Here's a sample of the xml <eveapi version="2"> <currentTime>2010-03-06 17:38:35</currentTime> <result> <rowset name="transactions" key="transactionID" columns="transactionDateTime,transactionID,quantity,typeName,typeID,price,clientID,clientName,stationID,stationName,transactionType,transactionFor"> <row transactionDateTime="2010-03-06 17:16:00" transactionID="1343566007" quantity="1" typeName="Co-Processor II" typeID="3888" price="1122999.00" clientID="1404318579" clientName="unseenstrike" stationID="60011572" stationName="Osmeden IX - Moon 6 - University of Caille School" transactionType="sell" transactionFor="personal" /> <row transactionDateTime="2010-03-06 17:15:00" transactionID="1343565894" quantity="1" typeName="Co-Processor II" typeID="3888" price="1150000.00" clientID="1404318579" clientName="unseenstrike" stationID="60011572" stationName="Osmeden IX - Moon 6 - University of Caille School" transactionType="sell" transactionFor="personal" /> </rowset> </result> <cachedUntil>2010-03-06 17:53:35</cachedUntil> </eveapi>

  • How to translate,use JSON in GWT?

    - by graybow
    I'm new in gwt. and need to know how to use JSON in gwt so i try this simple data loader but i'm still confuse. I create a project named 'tesdb3' in eclipse. I create the PHP side to access the database, and made the output as JSON.. I create the userdata.php in folder war. then I compile tesdb3 project. Folder tesdb3 and the userdata.php in war moved in local server(I use WAMP). I put the PHP in folder tesdb3. This is the result from my localhost/phpmyadmin/tesdb3/userdata.php [{"kode":"002","nama":"bambang gentolet"}{"kode":"012","nama":"Algiz"}] From that result I think the PHP side was working good.Then I create UserData.java as JSNI overlay like this: package com.tesdb3.client; import com.google.gwt.core.client.JavaScriptObject; class UserData extends JavaScriptObject{ protected UserData() {} public final native String getKode() /*-{ return this.kode; }-*/; public final native String getNama() /*-{ return this.nama; }-*/; public final String getFullData() { return getKode() + ":" + getNama(); } } Then Finally in the tesdb3.java: public class Tesdb3 implements EntryPoint { String url= "http://localhost/phpmyadmin/tesdb3/datauser.php"; private native JsArray<UserData> getuserdata(String Json) /*-{ return eval(json); }-*/; public void LoadData() throws RequestException{ RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, URL.encode(url)); builder.sendRequest(null, new RequestCallback(){ @Override public void onError(Request request, Throwable exception) { Window.alert("error " + exception); } public void onResponseReceived(Request request, Response response) { getuserdata(response.getText()); //this is how i use the userdata json(is this already translated?) UserData UD = null; String LKode =UD.getKode(); String LName =UD.getNama(); Label L = new Label(LKode+""+LName); RootPanel.get().add(L); } }); } public void onModuleLoad() { try { LoadData(); } catch (RequestException e) { e.printStackTrace(); } } } The result is blank(i use development mode). and there was an eror like this:(I show it just some part) 10:46:29.984 [ERROR] [tesdb3] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (ReferenceError): json is not defined fileName: http://localhost:1092 lineNumber: 2 stack: ("")@http://localhost:1092:2 My question is: How I use the translated Json in right way?? Is there any wrong use from my code? Is that necessary to move the compiled project to local server folder?(i do it following a tutorial from google). Sorry too many ask. but i'm really really confused.

  • Criteria query returns hydrated object in SQLite but not SqlServer

    - by Berryl
    I have a method that returns a resource fully hydrated when the db is SQLite but when the identical code is used by SqlServer the object is not fully hydrated. I'll explain that with the code after some brief background. I my domain various otherwise unrelated things like an Employee or a Machine can be used as a Resource that can be allocated to. In the object model an example of this would be: /// <summary>Wraps a <see cref="StaffMember"/> in a <see cref="ResourceBase"/>. </summary> public class StaffMemberResource : ResourceBase { public virtual StaffMember StaffMember { get; private set; } public StaffMemberResource(StaffMember staffMember) { Check.RequireNotNull<StaffMember>(staffMember); base.BusinessId = staffMember.Number.ToString(); base.Name = staffMember.Name.ToString(); base.OrganizationName = staffMember.Department.Name; StaffMember = staffMember; } [UsedImplicitly] protected StaffMemberResource() { } } And in the db tables, there is a table per class inheritance where the ResourceBase has a discriminator and the id of the actual resource (ie, StaffMember) StaffMember - 1 ---- M- ResourceBase - 1 ----- M - Allocation The Code public override StaffMemberResource BuildResource(IActivityService activityService) { var sessionFactory = _GetSessionFactory(); var session = sessionFactory.GetCurrentSession(); StaffMemberResource result; using (var tx = session.BeginTransaction()) { var propertyName = ExprHelper.GetPropertyName<StaffMember>(x => x.Number); var staff = session.CreateCriteria<StaffMember>() .Add(Restrictions.Eq(propertyName, new EmployeeNumber(_testData.Resource_1.BusinessId))) .UniqueResult<StaffMember>(); if (staff == null) { ... build up a staff member result = new StaffMemberResource(staff); } else { ////////// var property = ExprHelper.GetPropertyName<StaffMemberResource>(x => x.StaffMember); result = session.CreateCriteria<StaffMemberResource>() .Add(Restrictions.Eq(property, staff)) .UniqueResult<StaffMemberResource>(); } /////////// tx.Commit(); } return result; } It's that second criteria query that works "properly" with SQLite but not with SqlServer. By properly I mean that the employee numer is translated into a ResourceBase.BusinessId, Name is flattened out into a ResourceBase.Name, etc. Does anyone know why this might be? Cheers, Berryl

  • Is there any alternative to obfuscation to make it harder to get any string in javascript?

    - by MarceloRamires
    I use DropBox and I've had some trouble reaching to my files from other computers: I not always want to login to anything when I'm in a public computer, but I like being able to reach my stuff from wherever I am. So I've made a simple little application that when put in the public folder, ran and given the right UID, creates (still in your public folder) an HTML of all the content in the folder (including subfolders) as a tree of links. But I didn't risk loading it anywhere, since there are slightly private things in there (yes, I know that the folder's name is "PUBLIC"). So I've came up with the idea to make it a simple login page, given the right password, the rest of the page should load. brilliant!, but how? If I did this by redirecting to other HTML on the same folder, I'd still put the html link in the web history and the "url's accessed" history of the administrator. So I should generate itin the same page. I've done it. And currently the page is a textbox and a button, and only if you type in the right password (asked by the generator) the rest of the page loads. The fault is that everything (password, URL's) is easily reachable through the sourcecode. Now, assuming I only want to avoid silly people to get it all too easily, not make a bulletproof all-content-holding NSA certified website, I though about some ways to make these informations a bit harder to get. As you may have already figured, I use a streamwritter to write a .HTM file (head, loop through links, bottom), then it's extremely configurable, and I can come up with a pretty messy-but-working c# code, though my javascript knowledge is not that good. Public links in DropBox look like this: http://dl.dropbox.com/u/3045472/img.png Summarizing: How do I hide stuff (MAINLY the password, of course) in my source-code so that no bumb-a-joe that can read, use a computer and press CTRL+U can reach to my stuff too easily ? PS.: It's not that personal, if someone REALLY wants it, it could never be 100% protected, and if it was that important, I wouldnt put it in the public folder, also, if the dude really wants to get it that hard, he should deserve it. PS2.: "Use the ultra-3000'tron obfuscator!!11" is not a real answer, since my javascript is GENERATED by my c# program. PS3.: I don't want other solutions as "use a serverside application and host it somewhere to redirect and bla bla" or "compress the links in a .RAR file and put a password in it" since I'm doing this ALSO to learn, and I want the thrill of it =)

  • question about book example - Java Concurrency in Practice, Listing 4.12

    - by mike
    Hi, I am working through an example in Java Concurrency in Practice and am not understanding why a concurrent-safe container is necessary in the following code. I'm not seeing how the container "locations" 's state could be modified after construction; so since it is published through an 'unmodifiableMap' wrapper, it appears to me that an ordinary HashMap would suffice. EG, it is accessed concurrently, but the state of the map is only accessed by readers, no writers. The value fields in the map are syncronized via delegation to the 'SafePoint' class, so while the points are mutable, the keys for the hash, and their associated values (references to SafePoint instances) in the map never change. I think my confusion is based on what precisely the state of the collection is in the problem. Thanks!! -Mike Listing 4.12, Java Concurrency in Practice, (this listing available as .java here, and also in chapter form via google) /////////////begin code @ThreadSafe public class PublishingVehicleTracker { private final Map<String, SafePoint> locations; private final Map<String, SafePoint> unmodifiableMap; public PublishingVehicleTracker( Map<String, SafePoint> locations) { this.locations = new ConcurrentHashMap<String, SafePoint>(locations); this.unmodifiableMap = Collections.unmodifiableMap(this.locations); } public Map<String, SafePoint> getLocations() { return unmodifiableMap; } public SafePoint getLocation(String id) { return locations.get(id); } public void setLocation(String id, int x, int y) { if (!locations.containsKey(id)) throw new IllegalArgumentException( "invalid vehicle name: " + id); locations.get(id).set(x, y); } } // monitor protected helper-class @ThreadSafe public class SafePoint { @GuardedBy("this") private int x, y; private SafePoint(int[] a) { this(a[0], a[1]); } public SafePoint(SafePoint p) { this(p.get()); } public SafePoint(int x, int y) { this.x = x; this.y = y; } public synchronized int[] get() { return new int[] { x, y }; } public synchronized void set(int x, int y) { this.x = x; this.y = y; } } ///////////end code

  • How do you prevent IDisposable from spreading to all your classes?

    - by GrahamS
    Start with these simple classes... Let's say I have a simple set of classes like this: class Bus { Driver busDriver = new Driver(); } class Driver { Shoe[] shoes = { new Shoe(), new Shoe() }; } class Shoe { Shoelace lace = new Shoelace(); } class Shoelace { bool tied = false; } A Bus has a Driver, the Driver has two Shoes, each Shoe has a Shoelace. All very silly. Add an IDisposable object to Shoelace Later I decide that some operation on the Shoelace could be multi-threaded, so I add an EventWaitHandle for the threads to communicate with. So Shoelace now looks like this: class Shoelace { private AutoResetEvent waitHandle = new AutoResetEvent(false); bool tied = false; // ... other stuff .. } Implement IDisposable on Shoelace Buit now FxCop will complain: "Implement IDisposable on 'Shoelace' because it creates members of the following IDisposable types: 'EventWaitHandle'." Okay, I implement IDisposable on Shoelace and my neat little class becomes this horrible mess: class Shoelace : IDisposable { private AutoResetEvent waitHandle = new AutoResetEvent(false); bool tied = false; private bool disposed = false; public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } ~Shoelace() { Dispose(false); } protected virtual void Dispose(bool disposing) { if (!this.disposed) { if (disposing) { if (waitHandle != null) { waitHandle.Close(); waitHandle = null; } } // No unmanaged resources to release otherwise they'd go here. } disposed = true; } } Or (as pointed out by commenters) since Shoelace itself has no unmanaged resources, I might use the simpler dispose implementation without needing the Dispose(bool) and Destructor: class Shoelace : IDisposable { private AutoResetEvent waitHandle = new AutoResetEvent(false); bool tied = false; public void Dispose() { if (waitHandle != null) { waitHandle.Close(); waitHandle = null; } GC.SuppressFinalize(this); } } Watch in horror as IDisposable spreads Right that's that fixed. But now FxCop will complain that Shoe creates a Shoelace, so Shoe must be IDisposable too. And Driver creates Shoe so Driver must be IDisposable. and Bus creates Driver so Bus must be IDisposable and so on. Suddenly my small change to Shoelace is causing me a lot of work and my boss is wondering why I need to checkout Bus to make a change to Shoelace. The Question How do you prevent this spread of IDisposable, but still ensure that your unmanaged objects are properly disposed?
