  • Problems with Widgets in dojox DataGrid

    - by Kitson
    I am trying to include some editing Widgets in my dojox.grid.DataGrid seem to be having a lot of difficulty. I have tried everything I can think of to get it to work, but something just isn't going right. When I started having problems, I tried to copy almost exactly from the grid tests and model my "breakout" of code just like that, but without success. Basic editing of the Grid seems to work. In the example below, the "Events" column allows edits, but the two columns that are using the cellType attribute don't work. In fact they also seem to ignore the other attributes (like the styles) which would seem to indicate that some sort of issue was run into, but there is nothing in FireBug. Also I get the same behaviour between Chrome and Firefox. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Insert title here</title> <link id="themeStyles" rel="stylesheet" href="javascript/dojotoolkit/dijit/themes/tundra/tundra.css"> <style type="text/css"> @import "css/gctilog.css"; @import "javascript/dojotoolkit/dojo/resources/dojo.css"; @import "javascript/dojotoolkit/dijit/themes/tundra/tundra.css"; @import "javascript/dojotoolkit/dojox/grid/resources/Grid.css"; @import "javascript/dojotoolkit/dojox/grid/resources/tundraGrid.css"; @import "javascript/dojotoolkit/ocp/resources/MultiStateCheckBox.css"; </style> <script type="text/javascript" src="javascript/dojotoolkit/dojo/dojo.js" djConfig="parseOnLoad:true, isDebug:true, locale:'en-gb'"></script> <script type="text/javascript"> dojo.require("dojo.currency"); dojo.require("dijit.dijit"); dojo.require("dijit.form.HorizontalSlider"); dojo.require("dojox.data.JsonRestStore"); dojo.require("dojox.grid.DataGrid"); dojo.require("dojox.layout.ExpandoPane"); dojo.require("dojox.timing"); dojo.require("ocp.MultiStateCheckBox"); dojo.require("dojo.parser"); formatCurrency = function(inDatum){ return isNaN(inDatum) ?

It would seem to be fundamental, but I just can't seem to see it. [EDIT] What I have done instead is return a dijit Widget using the formatter to return a widget. So in the declarative model, I specify something like this: <th field="type" formatter="getMultiField" width="10em" styles='text-align: center;'>Type</th> And then I wrote a JavaScript function like the below to return the widget I wanted. function getMultiField(value) { var jsonValue = JSON.parse(value); //I provide the value of the widget as JSON //from my data store, so I need to parse it var control = new ocp.MultiStateCheckBox({ //my custom widget id : "dMSCB"+(new Date).getTime()+Math.ceil(Math.random()*100000), //generate a unique ID value : jsonValue.value, onChange : function (value {...}) //code to manipulate the underlying data store }); return control; //The dojo 1.4 grid can handle a returned Widget }

  • Modal MessageBox for ASP.NET without jQuery

    - by Joe
    I have an assembly with custom ASP.NET server controls that is used in several, mostly in-house, ASP.NET 2.0 applications. The server controls use simple modal popup messageboxes, which are currently implemented using the javascript alert and confirm functions. I want to release a new version of this assembly that uses a better solution for messageboxes, including support for Yes/No buttons. The appearance would be something like a simplified version of the Ajax Control Toolkit ModalPopup extender (sample here). My constraints are that this should be as easy as possible to integrate into existing ASP.NET 2.0 applications without introducing new dependencies: ideally just drop in a new version of the assembly, that contains all the javascript it needs as an embedded resource, and possibly a CSS file. Because of this constraint, I am not considering solutions I've seen that use jquery, or the ASP.NET Ajax Control Toolkit, which appears to require adding elements to pages that use the extenders (ScriptManagers and the like). Any recommendations?

  • ASP.NET MVC Route Default values

    - by Sadegh
    hi, i defined two routes in global.asax like below context.MapRoute("HomeRedirect", "", new { controller = "Home", action = "redirect" }); context.MapRoute("UrlResolver", "{culture}/some", new { culture = "en-gb", controller = "someController", action = "someAction" }, new { culture = new CultureRouteConstraint() }); according to above definition, when user request mysite.com/ redirect action of HomeController should be called and in that: public class HomeController : Controller { public ActionResult Redirect() { return RedirectToRoute("UrlResolver"); } } i want to redirect user to second defined route on above, so also i specified default values for that and some Constraint for each of those. but when RedirectToRoute("UrlResolver") turns, no default values passed to routeConstraints on second route and No route in the route table matches the supplied values shows. update my CultureRouteConstraint: public class CultureRouteConstraint : IRouteConstraint { bool IRouteConstraint.Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { try { var parameter = values[parameterName] as string; return (someCondition(parameter)); } catch { return false; } } } now values parameter haven't culture key/value, but route parameter have that.

  • Android: Filtering a SimpleCursorAdapter ListView

    - by Diego Tori
    Right now, I'm running into issues trying to implement a FilterQueryProvider in my custom SimpleCursorAdapter, since I'm unsure of what to do in the FilterQueryProvider's runQuery function. In other words, since the query that comprises my ListView basically gets the rowID, name, and a third column from my databases's table, I want to be able to filter the cursor based on the partial value of the name column. However, I am uncertain of whether I can do this directly from runQuery without expanding my DB class since I want to filter the existing cursor, or will I have to create a new query function in my DB class that partially searches my name column, and if so, how would I go about creating the query statement while using the CharSequence constraint argument in runQuery? I am also concerned about the performance issues associated with trying to run multiple queries based on partial text since the DB table in question has about 1300-1400 rows. In other words, would I run into a bottleneck trying to filter the cursor?

  • Hibernate mapping one-to-many problem

    - by Xorty
    Hello, I am not very experienced with Hibernate and I am trying to create one-to-many mapping. Here are relevant tables: And here are my mapping files: <hibernate-mapping package="com.xorty.mailclient.server.domain"> <class name="Attachment" table="Attachment"> <id name="id"> <column name="idAttachment"></column> </id> <property name="filename"> <column name="name"></column> </property> <property name="blob"> <column name="file"></column> <type name="blob"></type> </property> <property name="mailId"> <column name="mail_idmail"></column> </property> </class> </hibernate-mapping> <hibernate-mapping> <class name="com.xorty.mailclient.server.domain.Mail" table="mail"> <id name="id" type="integer" column="idmail"></id> <property name="content"> <column name="body"></column> </property> <property name="ownerAddress"> <column name="account_address"></column> </property> <property name="title"> <column name="head"></column> </property> <set name="receivers" table="mail_has_contact" cascade="all"> <key column="mail_idmail"></key> <many-to-many column="contact_address" class="com.xorty.mailclient.client.domain.Contact"></many-to-many> </set> <list name="attachments" cascade="save-update, delete" inverse="true"> <key column="mail_idmail" not-null="true"/> <index column="fk_Attachment_mail1"></index> <one-to-many class="com.xorty.mailclient.server.domain.Attachment"/> </list> </class> </hibernate-mapping> In plain english, one mail has more attachments.

  • how to serialize a DataTable to json or xml

    - by loviji
    Hello, i'm trying to serialize DataTable to Json or XML. is it possibly and how? any tutorials and ideas, please. For example a have a sql table: CREATE TABLE [dbo].[dictTable]( [keyValue] [int] IDENTITY(1,1) NOT NULL, [valueValue] [int] NULL, CONSTRAINT [Psd2Id] PRIMARY KEY CLUSTERED ( [keyValue] ASC )WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] C# code: string connectionString = "server=localhost;database=dbd;uid=**;pwd=**"; SqlConnection mySqlConnection = new SqlConnection(connectionString); string selectString = "SELECT keyValue, valueValue FROM dicTable"; SqlCommand mySqlCommand = mySqlConnection.CreateCommand(); mySqlCommand.CommandText = selectString; SqlDataAdapter mySqlDataAdapter = new SqlDataAdapter(); mySqlDataAdapter.SelectCommand = mySqlCommand; DataSet myDataSet = new DataSet(); mySqlConnection.Open(); string dataTableName = "dictionary"; mySqlDataAdapter.Fill(myDataSet, dataTableName); DataTable myDataTable = myDataSet.Tables[dataTableName]; //now how to serialize it?

  • Testing an XQuery Transformation

    Hi, I'm using Workshop for Weblogic and I'm testing an XQuery Transformation. Both MFL and XSD are valid.

  • Hibernate: Parent/Child relationship in a single-table

    - by Dee
    I hardly see any pointer on the following problem related to Hibernate. This pertains to implementing inheritance using a single database table with a parent-child relationship to itself. For example: CREATE TABLE Employee ( empId BIGINT NOT NULL AUTO_INCREMENT, empName VARCHAR(100) NOT NULL, managerId BIGINT, CONSTRAINT pk_employee PRIMARY KEY (empId) ) Here, the managerId column may be null, or may point to another row of the Employee table. Business rule requires the Employee to know about all his reportees and for him to know about his/her manager. The business rules also allow rows to have null managerId (the CEO of the organisation doesn't have a manager). How do we map this relationship in Hibernate, standard many-to-one relationship doesn't work here? Example code would be appreciated.

  • How to share cookies across multiple Apache Virtual Hosts

    - by puk
    This question is generally phrased as "How to share cookies across multiple subdomains" and the answer is generally to use the leading dot like so setcookie( 'id', 0, time()+30*3600, '/', '.example.com' ); which means that the cookie is available to all subdomains of example.com. However, the / path I suspect adds the constraint that all subdomains must be physically under the same tree. The PHP documentation states path The path on the server in which the cookie will be available on. If set to '/', the cookie will be available within the entire domain. If set to '/foo/', the cookie will only be available within the /foo/ directory and all sub-directories such as /foo/bar/ of domain. The default value is the current directory that the cookie is being set in. Is it possible to share cookies if one has two (Apache) Virtual Hosts set up with document roots at, for example www.one.example.com ? /var/www/example1 www.two.example.com ? /var/www/example2

  • Covariance and Contravariance on the same type argument

    - by William Edmondson
    The C# spec states that an argument type cannot be both covariant and contravariant at the same time. This is apparent when creating a covariant or contravariant interface you decorate your type parameters with "out" or "in" respectively. There is not option that allows both at the same time ("outin"). Is this limitation simply a language specific constraint or are there deeper, more fundamental reasons based in category theory that would make you not want your type to be both covariant and contravariant? Edit: My understanding was that arrays were actually both covariant and contravariant. public class Pet{} public class Cat : Pet{} public class Siamese : Cat{} Cat[] cats = new Cat[10]; Pet[] pets = new Pet[10]; Siamese[] siameseCats = new Siamese[10]; //Cat array is covariant pets = cats; //Cat array is also contravariant since it accepts conversions from wider types cats = siameseCats;

  • How to access the Principal from a Java service object without using FlexContext?

    - by Marplesoft
    We're building some Java objects that are exposed via BlazeDS to our flex client application. So basically the BlazeDS messagebroker servlet instantiates and invokes methods on these objects in response to client requests. Works great. We're using app server-based authentication and have set up a security constraint on the <destination> elements in the remoting-config.xml file element to prevent unauthenticated clients from being able to access these remote java objects. Again, works fine. However, there are several places within the implementation of these java objects where we want to get the currently logged on user's username. Right now we are doing this via FlexContext.getUserPrincipal(), which gives access to this but we have a nagging concern that we don't like the idea that the implementation of these objects (the service layer) has a hard dependency on a BlazeDS class. But we're not sure how else to get access to this. The same applies to accessing the ServletContext and such. Any ideas?

Now when i start this bundle its complaining Missing Constraint: Import-Package: com.sun.management; version="0.0.0" I had used the OperatingSystemMXBean to get access to stats on the JVM. My question is can I use this class inside an OSGI container and if so how? Or should I use some other way to monitor my application. I was making an RMI call to the application from a web frontend to get the nodes performance figures pre OSGi.

  • EF 4.0 - Many to Many relationship - problem with deletes

    - by chugh97
    My Entity Model is as follows: Person , Store and PersonStores Many-to-many child table to store PeronId,StoreId When I get a person as in the code below, and try to delete all the StoreLocations, it deletes them from PersonStores as mentioned but also deletes it from the Store Table which is undesirable. Also if I have another person who has the same store Id, then it fails saying "The DELETE statement conflicted with the REFERENCE constraint \"FK_PersonStores_StoreLocations\". The conflict occurred in database \"EFMapping2\", table \"dbo.PersonStores\", column 'StoreId'.\r\nThe statement has been terminated" as it was trying to delete the StoreId but that StoreId was used for another PeronId and hence exception thrown. Person p = null; using (ClassLibrary1.Entities context = new ClassLibrary1.Entities()) { p = context.People.Where(x=> x.PersonId == 11).FirstOrDefault(); List<StoreLocation> locations = p.StoreLocations.ToList(); foreach (var item in locations) { context.Attach(item); context.DeleteObject(item); context.SaveChanges(); } }

  • Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key"

    Hello world. Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key" scheme? Problem facts: I am using Oracle XE. I have implemented the following table and trigger: CREATE TABLE "USERS" ( "ID" NUMBER(38,0), "USER_NAME" VARCHAR2(50), "PASSWORD" VARCHAR2(50), "EMAIL" VARCHAR2(100), CONSTRAINT "USERS_PK" PRIMARY KEY ("ID") ENABLE ) / CREATE OR REPLACE TRIGGER "BI_USERS" before insert on "USERS" for each row begin select "USERS_SEQ".nextval into :NEW.ID from dual; end; / ALTER TRIGGER "BI_USERS" ENABLE / MyGeneration / Doodads created the following stored proc...

    Hi, I saw this question in a forum about how an application can be developed that can keep track of the installation date and show trail period expired after 30 days of usage. The only constraint is not to use the external storage of any kind. Question: How to achieve this? Thanks Bala --Edit I think its easy to figure out the place to insert a question work. Anyway, I will write the question clearly. "external storage" means don't use any kind of storage like file, registry, network or anything. You only have your program.

  • Upload file via HTTP from VBA (WinHTTP)

    - by chiccodoro
    Hi all, I'm trying to HTTP upload a binary file programmatically from within VBA. I intend to put an ASPX page on the server. I know there are lots of nice ways to do that (e.g. use web service instead of aspx), but my constraint is that it must run in VBA (in an excel file), and that I cannot install any additional components on the client. So I guess I'll use WinHTTP, and I've found several examples to post form data, but not to post a binary file. I probably need to base64 the file contents? If so, please let me know. If I can make WinHTTP do file encoding for me, please let me know. If there is a much better way to reach my goal (Upload file from within VBA, server needn't necessarily be ASPX, could be a ASP.NET-Web service as well), please let me know... Thx, chiccodoro

  • Foreign key onto weak entity set in MS SQL Server 2008?

    - by Nic Waller
    I'm using Microsoft SQL Server 2008 Management Studio to create a relational schema by following an Entity-Relationship diagram. (included below; unrelated details removed) Until now, primary and foreign keys have been working as expected. But when I try to create a foreign key from the entity relationship takes onto the weak entity set section, I get an error. Section is identified by a composite primary key in the context of course, which has course_id as a primary key. Therefore, the primary key of section is a 4-way composite key. The entity relationship takes needs to refer to section, so it includes all 4 primary attributes from section in it's own primary key. When trying to establish a foreign key relationship from takes to section, Studio gives the following error: The columns in table 'section' do not match an existing primary key or UNIQUE constraint. Am I doing something wrong, or is this an unsupported configuration? I can provide more details or the SQL schema if necessary.

  • 100% width bg images not extending on horizontal scroll

    - by Fuego DeBassi
    I'm noticing this issue. I made a quick screen capture to demonstrate: http://dl.dropbox.com/u/904456/2010-06-14_2323.swf Basically when you have a min-width set and the viewport goes under that constraint, a horizontal scroll bar appears. Pretty much what you would expect, but when you scroll over horizontally all elements that are suppose to extend across the entire width of the page and have background images/colors different from the body do not extend. If you resize the viewport it seems to catch up. Is this a known issue? You can see it on a lot of sites, http://gowalla.com for example. Any ideas?

  • Adding a JPanel to another JPanel having TableLayout

    I am trying to develop a map editor in java. My map window receives as a constructor a Map object. From that map object i am able to retrieve the Grid and every item in the grid along with other getters and setters. The problem is that even though the Mapping extends JComponent, when I place it in a panel it is not painted. I have overridden the paint method to satisfy my needs. Here is the code, maybe you could help me. public class MapTest extends JFrame implements ActionListener { private JPanel mainPanel; private JPanel mapPanel; private JPanel minimapPanel; private JPanel relationPanel; private TableLayout tableLayout; private JPanel tile; MapTest(Map map) { mainPanel = (JPanel) getContentPane(); mapPanel = new JPanel(); populateMapPanel(map); mainPanel.add(mapPanel); this.setPreferredSize(new Dimension(800, 600)); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); } private double[][] generateTableLayoutSize(int x, int y, int size) { double panelSize[][] = new double[x][y]; for (int i = 0; i < x; i++) { for (int j = 0; j < y; j++) { panelSize[i][j] = size; } } return panelSize; } private void populateMapPanel(Map map) { double[][] layoutSize = generateTableLayoutSize(map.getMapGrid().getRows(), map.getMapGrid().getColumns(), 50); tableLayout = new TableLayout(layoutSize); for(int i = 0; i < map.getMapGrid().getRows(); i++) { for(int j = 0; j < map.getMapGrid().getColumns(); j++) { tile = new JPanel(); tile.setName(String.valueOf(((Mapping)map.getMapGrid().getItem(i, j)).getCharacter())); tile.add(map.getMapItem(i, j)); String constraint = i + "," + j; mapPanel.add(tile, constraint); } } mapPanel.validate(); mapPanel.repaint(); } public void actionPerformed(ActionEvent e) { throw new UnsupportedOperationException("Not supported yet."); } } My Mapping Class public class Mapping extends JComponent implements Serializable{ private BufferedImage image; private Character character; //default public Mapping() { super(); this.image = null; this.character = '\u0000'; } //Mapping from image and char public Mapping(BufferedImage image, char character) { super(); this.image = image; this.character = character; } //Mapping from file and char public Mapping(File file, char character) { try { this.image = ImageIO.read(file); this.character = character; } catch (IOException ex) { System.out.println(ex); } } public char getCharacter() { return character; } public void setCharacter(char character) { this.character = character; } public BufferedImage getImage() { return image; } public void setImage(BufferedImage image) { this.image = image; repaint(); } @Override /*Two mappings are consider the same if -they have the same image OR -they have the same character OR -both of the above*/ public boolean equals(Object mapping) { if (this == mapping) { return true; } if (mapping instanceof Mapping) { return true; } //WARNING! equals might not work for images return (this.getImage()).equals(((Mapping) mapping).getImage()) || (this.getCharacter()) == (((Mapping) mapping).getCharacter()); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); //g.drawImage(image, 0, 0, null); g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), null); } // @Override // public Dimension getPreferredSize() { // if (image == null) { // return new Dimension(10, 10); //instead of 100,100 set any prefered dimentions // } else { // return new Dimension(100, 100);//(image.getWidth(null), image.getHeight(null)); // } // } private void readObject(java.io.ObjectInputStream in) throws IOException, ClassNotFoundException { character = (Character) in.readObject(); image = ImageIO.read(ImageIO.createImageInputStream(in)); } private void writeObject(java.io.ObjectOutputStream out) throws IOException { out.writeObject(character); ImageWriter writer = (ImageWriter) ImageIO.getImageWritersBySuffix("jpg").next(); writer.setOutput(ImageIO.createImageOutputStream(out)); ImageWriteParam param = writer.getDefaultWriteParam(); param.setCompressionMode(ImageWriteParam.MODE_EXPLICIT); param.setCompressionQuality(0.85f); writer.write(null, new IIOImage(image, null, null), param); } }

  • Hibernate @OneToOne @NotNull

    - by Marty Pitt
    Is it valid to declare @OneToOne and @NotNull on both sides of a relationship, such as: class ChangeEntry { @OneToOne(cascade=CascadeType.ALL) @NotNull ChangeEntryDetails changeEntryDetails; } class ChangeEntryDetails { @OneToOne(cascase=CascadeType.ALL) @NotNull ChangeEntry changeEntry; } I can't find anything that says this is invalid, but it seems that during persistence at least one side of the relationship must be violated. (Eg., if writing changeEntry first, changeEntryDetails will be null temporarily). When trying this, I see an exception thrown not-null property references a null or transient value. I'd like to avoid relaxing the constraint if possible, because both sides must be present.

  • EF 4 - associations with keys that dont match

    - by Steve Ward
    We're using POCOs and have 2 entities: Item and ItemContact. There are 1 or more contacts per item. Item has as a primary key: ItemID LanguageCode ItemContact has: ItemID ContactID We cant add an association with a referrential constraint as they have differing keys. There isnt a strict primary / foreign key as languageCode isnt in ItemContact and ContactID isnt in Item. How can we go about mapping this with an association for contacts for an item if there isnt a direct link but I still want to see the contacts for an item? One of the entities originates in a database view so it is not possible to add foreign keys to the database Thanks Stephen Ward
