• Is there any free, open source php CMS\framework for described case?

  - by Ole Jak

  I want that cms\framework to create me tables like "Users" "Cameras" and so on and declare classes and simple default methods for them (like paged sql relults and so on). I mean I say to it: I want Users to have ID, SpecialNumber and Name Flilds. and I want to get from it class for table generation (to call it once) and class containing methods such as Search by ID, SpecialNumber and Name, Create User, Delit User and so on functions. Is there any framework/cms like this for working with CODE not ui's and so on... so to say PHP generator or something... The result should be as that framework free as possible. So Is there any free, open source php CMS\framework for described case?

• what is serialization and how it works

  - by Rozer

  I know the serialization process but have't implemented it. In my application i have seen there are various classes that has been implemented serilizable interface. consider following class public class DBAccessRequest implements Serializable { private ActiveRequest request = null; private Connection connection = null; private static Log log = LogFactory.getLog(DBAccessRequest.class); public DBAccessRequest(ActiveRequest request,Connection connection) { this.request = request; this.connection = connection; } /** * @return Returns the DB Connection object. */ public Connection getConnection() { return connection; } /** * @return Returns the active request object for the db connection. */ public ActiveRequest getRequest() { return request; } } just setting request and connection in constructor and having getter setter for them. so what is the use of serilizable implementation over here...

• Are there any good materials or examples on creating a custom Designer in the Delphi IDE

  - by Mark Elder

  I am working on creating a custom form designer in the Delphi IDE. I'm trying to use the RegisterCustomModule, TBaseCustomModule, and ICustomModule functions, classes, and interfaces. My first question on this pointed me to the Delphi Developer's Handbook and the idea that I could even create a custom form designer. However, that book seems to be all Delphi 3 information and things have really changed since then. I'm not finding any material in the Delphi Help file, and searches have not returned very much. I did find the Accidental Programmer's page on the Open Tools, but that looks like it was last up dated in 1998? It does at least have the correct unit names and uses the new interfaces. I'm willing to track down and buy an older book if that is the best reference.

• Simple ant build script that supports src/ and test/?

  - by M-x

  Currently I use an IDE for all my builds and unit tests. Now I have a need to use ant. I found a few simple ant build.xml scripts but they didn't support a separate Junit test/ dir. My projects are structured as follows: src/ com/foo/ com/bar/ test/ -- Mirror of src/, with all *Test.java files. com/foo/ com/bar/ lib/ -- All Java libs, including junit 4. How can a construct a small ant script that builds my src/ and test/ Java classes then runs all my JUnit tests?

• What are the requirements of a collection type when model binding?

  - by Richard Ev

  I have been reviewing model binding with collections, specifically going through this article http://weblogs.asp.net/nmarun/archive/2010/03/13/asp-net-mvc-2-model-binding-for-a-collection.aspx However, the model I would like to use in my code does not implement collections using generic lists. Instead it uses its own collection classes, which inherit from a custom generic collection base class, the declaration of which is public abstract class CollectionBase<T> : IEnumerable<T> The collections in my POSTed action method are all non-null, but contain no elements. Can anyone advise?

• Creating a relative path to a Database in Asp.net for a library

  - by Greener

  In school I am part of a team of four working to create a GUI to translate the paper records of a made-up company and their functionality to a digital format. We're using an ASP.NET website for this purpose. Basically we use stored procedures and C# classes to represent the database. The folder we're using for the project contains the site and the libraries in separate folders. If I try to open the site from the folder containing both these elements the site will not run. I want to know if there is some way I can set up a relative path to the database in the Settings.Settings.cs file (or by some other means) of my libraries so I don't have to constantly change the database location for the connection string value every time we move the project. I suppose I should also mention that the database is in an App_Data folder.

• Casting to specific asp.net page type

  - by DEH

  I have an asp.net page with a code-behind class definition as follows: public partial class examplepage : System.Web.UI.Page I'd like to set a public property within the page that I can reference from other classes. My understanding is that if I cast to examplepage then I should be able to get at the public property that is specific to example page, as in: string test=((examplepage)HttpContext.Current.Handler).propertyX; However, when I try casting as above the compiler does not recognise examplepage. Can anyone tell me how I can cast? I have no specific namespaces defined. Thanks

• Bitmap manipulation as a referenced object

  - by John Maloney

  I am working with a Bitmap object that I add annotations or copyright material to the image and then return the modified bitmap. My problem is that the Bitmap won't hold the changes made to it as it moves along the chain. I am treating it as a reference type and would assume that as it gets passed to each class it would carry the changes made to it. I have verified that the code inside of the MarkImage() classes does function, but which ever one gets called last is the one that has changes. Public Shared Function GetImage(ByVal imageDef As IImageDefinition) As Bitmap Dim image As Bitmap = Drawing.Image.FromFile(imageDef.Path) If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutCopyright) Then image = New MarkCopyrightImage(image).MarkImage() End If If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutAnnotations) Then image = New MarkAnnotateImage(image).MarkImage() End If Return image End Function How do I write changes to a bitmap object and then pass that object to another class while maintaining the changes? Answers in C# or VB are fine? Thanks

• C++ inheritance question

  - by user233973

  Hi guys, I have a C++ inheritance related question. I have a set of classes like this (I have not given the complete class structure coz I am lazy :) ). I want to access chiComponent class public methods using com pointer. How should I go about it? Note that I am having to change the object which "com" is pointing to in a lot of places. So I do not think I can have another chiComponent *ccom = <some_cast> com; ccom.chiComponentMethod() How should I go about it? class Component{ }; class chiComponent : public Component { public: void chiComponentMethod() { cout << "Hi! Chi component function called!!"; } } class parent { protected: Component *com; }; class child : public parent{ public: child() { com = new chiComponent(); } } Regards Arun

• "Reloading" Bindings in Ninject2?

  - by Michael Stum

  I'm using Ninject2 for DI and I have a Module that loads data from a config file. I wonder if there is a way to tell the Kernel or the Module to reload the config? (I can trigger that through code if needed) What worries me is the lifetime of existing objects. Say I have ITest bound to TestImpl1 in Singleton Scope and I change the config to bind ITest to TestImpl2 instead. All new requests should get TestImpl2, but the classes that already requested TestImpl1 before obviously keep it. However, what if all users of TestImpl1 are gone - will TestImpl1 be properly garbage collected and disposed in case it implements IDisposable? Or will it just be orphaned? Do I have to loop through each type and call Unbind/Bind on it? Or can I just unload the entire Module and reload it while still managing any existing object?

• MVC + Repository Pattern - Still depends on Data Model?

  - by Jack

  I've started a project for school in which I am using ASP.NET MVC 2 + LINQ2SQL, and a business layer so my UI doesnt interact with the DB directly. My question is this: In my MVC project, when bringing up views and passing around data, I still have to include my Data project for access to the classes in my Linq2Sql project. Is this correct? Example: Controller: ClassesRepository cr = new ClassesRepository(); // this is from my Business project Class classToEdit = cr.GetByClassId(id); // "Class" is from my data project I still have to reference the Class class in my linq2sql data project - shouldn't my UI be completely independent of my data layer? Or maybe I'm going about this all wrong.

  I am working on a chat application for android. This chat application is for sending messages from one device to another using internet(GPRS,3G,etc) from this application. please tell me a way to implement this. I thought using web services is more data(internet) consuming and less efficient.is this right? I worked on server and client sockets. I ran both server and client classes in single device and messages can be transfered from client socket to server socket and vice versa.Now i want to message between two devices using server socket on web server and how to connect to server from Android Devices. please help me thank you very much.

• Java import from other directory

  - by heldopslippers

  Hi People! I am building a Enterprise Service Bus (ESB) with Java. I won't get into details But I have to build multiple servers who make use of the same classes. I have the following directory structure: /server1 -Main.java /server2 -Main.java /com -Database.java I want to import from the Main.java class for example the Database.class. But of course the following statements won't work: import com.Database; I am working with the javac compiler in the command line (so not eclipse stuff or whatever. just TextMate and the command line). And I found a (pretty stupid) solution by creating a symbolic link in the servers to the com directory. But that is not really an ideal solution. Does anybody have a better one?? THANXS in advanced!! :D

• How to load modules in Java

  - by gerardorn

  I'm building a server that loads modules. Each module is a .jar file. Inside the jar there's all the classes that the module needs. The server needs to read the jar, find the main class (it doesnt have the main method on it is just the class that makes the module work but not as a different program), build an object of that class and store it in a vector of modules so that it can acces to a specific module depending on the job to be done. How can I do that? As far as the server, it is listening and receiving request, but there's no modules to delegate the job to, since my vector of modules is empty.

• What is a good solution to link different tables in Hibernate based on some field value?

  - by serg555

  I have article table and several user tables a_user, b_user, ... with exactly the same structure (but different data). I can't change anything in *_user tables except their table name prefix but can change everything else (user tables contain only user information, there is nothing about article or user_type in them). I need to link article to a user (many-to-one), but user table name is defined by user_type field. For example Article table record: ... user_id="5" user_type="a" means that it is linked to a user with id=5 from a_user table (id 5 is not unique in users scope, each user table can have its id 5). Any suggestions how to handle this situation? How can I map this relation in Hibernate (xml mapping, no annotations) so it will automatically pick up correct user for an article during select/update? How should I map user tables (one or multiple classes?)? I would need to run some queries like this: from Article a where a.userType=:type and a.user.name=:name Thanks.

• frame variable cannot be found

  - by Umzz Mo

  I am making 3 board games, and I have started my coding off in one class. Now that i wanted to move around it is giving me problems. In my view class I just want to have the main frame where users can pick from the games. And in the other views, i.e the childrens of view class i want to have the interface for the actual games. Now that the Jframe frame = new frame was created in the parent class, it cannot find the variable frame in the children classes.

• Real-world examples of populating a GWT CellTable using a clean MVP pattern?

  - by piehole

  We are using the GWT-Presenter framework and attempting to use CellTable to put together an updateable grid. It seems as though several of the GWT constructs for CellTable don't lend themselves to easily breaking up the logic into clean view and presenter code. Examples: 1) Within the View's constructor, the CellTable is defined and each column is created by anonymous inner classes that extend the Column class to provide the onValue() method. 2) The FieldUpdater interface must be implemented to provide logic to execute when a user alters data in a cell. This seems like it would best fit in the Presenter's onBind() method, but FieldUpdaters often need access to the Cell or Column which belong in the view. CellTable does not have accessor methods to get hold of the Columns or Cells, so it seems the only way for the Presenter to get them is for me to create a multitude of member variables on the View and accessors on my Display interface. Can anyone provide good examples for dealing with CellTable in GWT-Presenter or a comparable MVP

• Is there a server side API for Team Foundaion Server

  - by Ralph Shillington

  It would seem there is precious little documentation on programming against a TFS 2010 instance. What bits I have found, have next to nothing in the case of documentation beyond barebones listing of client access classes and their members, most likely autogenerated from the code comments. As I'm interested in building a silverlight client against TFS, I will need access to server side API (ideally the silverlight app will talk to my server (mainly for work items) and my server will in turn talk to the TFS server for the goods. Where is the doumentation (if any) for this kind of TFS integration?

• Localizing validation (error) messages in Grails

  - by John

  Hi, I try to localize error messages from the Domain classes. This is possible with the default error messages, e.g.: default.blank.message=Property [{0}] cannot be blank and localized attribute names, e.g.: customer.address.label=Customer address Where "Customer" is my domain class and address is its attribute. My problem is that I can't localize some attributes because I need specific error messages. E.g: has.to.be.a.number=Property [{0}] has to be a number contingent.size.label=Contingent size. But the message I get is "Property [size] has to be a number" instead of "Property [Contingent size] has to be a number". The messages I cant localize are following: - Property [{0}] has to be a number - Property [{0}] has to be a valid date // I can't use g:datePicker in this context

• PHP and Java interoperablity

  - by Jack

  I am working on windows using tomcat 6 and PHP/Java Bridge. I know how to access a Java file from PHP but how do we do it the other way i.e accessing PHP from Java <?php require_once("java\Java.inc"); $systemInfo = new Java("java.lang.System"); print "Total seconds since January 1, 1970: ".$systemInfo->currentTimeMillis(); ?> Also how do I access Java classes that are created by me. Do I write a CLASSPATH env variable or change the php.ini config file?

• Why does Java ArrayList use per-element casting instead of per-array casting?

  - by user1111929

  What happens inside Java's ArrayList<T> (and probably many other classes) is that there is an internal Object[] array = new Object[n];, to which T Objects are written. Whenever an element is read from it, a cast return (T) array[i]; is done. So, a cast on every single read. I wonder why this is done. To me, it seems like they're just doing unnecessary casts. Wouldn't it be more logical and also slightly faster to just create a T[] array = (T[]) new Object[n]; and then just return array[i]; without cast? This is only one cast per array creation, which is usually far less than the number of reads. Why is their method to be preferred? I fail to see why my idea isn't strictly better?

• Is there a way to expose multiple WCF services through a single endpoint?

  - by mafutrct

  I currently offer a service with many methods via WCF. I'd like to refactor so the single service is split into multiple classes, each offering a different set of functionality. However, I'd prefer to still have a single connection to the client. Is this possible? I guess the answer is No, so how should I solve this issue? Is there a workaround? Or is my idea completely stupid and I should change the design of the application?

• In Eclipse, how do I change the default modifiers in the class/type template?

  - by gustafc

  Eclipse's default template for new types (Window Preferences Code Style Code Templates New Java Files) looks like this: ${filecomment} ${package_declaration} ${typecomment} ${type_declaration} Creating a new class, it'll look something like this: package pkg; import blah.blah; public class FileName { // Class is accessible to everyone, and can be inherited } Now, I'm fervent in my belief that access should be as restricted as possible, and inheritance should be forbidden unless explicitly permitted, so I'd like to change the ${type_declaration} to declare all classes as final rather than public: package pkg; import blah.blah; final class FileName { // Class is only accessible in package, and can't be inherited } That seems easier said than done. The only thing I've found googling is a 2004 question on Eclipse's mailing list which was unanswered. So, the question in short: How can I change the default class/type modifiers in Eclipse? I'm using Eclipse Galileo (3.5) if that matters.

• How do you plan for starting a new web system?

  - by Kerry

  I've been creating more and more systems recently and I find more and more planning and preparation I do before starting the project. I determine what libraries or frameworks I will be using, what languages, the basic architecture of how the site will flow, etc. I've also heard of other design processes such as hanging styrofoam balls to show where classes are and how they relate, which is a process I've never heard of nor do I know how it works. Is there any software that helps with this process? Are there any guidelines or steps or do you have a recommended set of steps or guidelines that you follow when designing a new project?
