WCF serialization issue when moving existing class properties to newly created base class
Using the example above, I overloaded the property "B" in the derived class and had it refer to the Base class (I'm working in VB, sorry): #region "This shenanigans prevents breaking the contract when moving some properties to the base class. <DataMember()> Public Overloads Property B() As String Get Return MyBase.B End Get Set(value As String) MyBase.B = value End Set End Property #End Region This way my base class methods can still operate on B. If we ever get around to implementing wcf versioning, or have some other need to change the contract, I can strip out that overload in the derived class and everything should still just work. -JG

QWT designer plugin is inaccesable via QtCreator built-in designer
The reason might be on the compatibility of your QTCreator with the the ACTUAL QT framework you built QWT against. The "Qt 5.1.1 for Windows 64-bit (VS 2012, OpenGL, 522 MB)" package provided in QT-Project.org/Download has the QT libraries built against MSVCR110 (C++ 2012) 64 bits where as the actual QTCreator.exe is built against MSCVR100 (C++ 2010). That's why the QWT plugin load successfully form the stand-alone QT Designer that comes in the QT framework, but not on the QT creator that comes in the Tools/ directory. To check this, load the QTCreator executable in Dependency Walker and you'll see. My recommendation is that you download the source code of QT, build it with your compiler and then compile the QWT using the same compiler. A bit tedious but at least you'll be sure that your

Qt Designer: Changing the base class of a window
To change the base class you could only change the : public QMainWindow to : public QWidget (or vice-versa) in the header-file and of course also the *.cpp. Basically all three are QWidgets, each with special functionality or for specific purposes. As far as I know the QMainWindow has toolbars, menubars and docks, a QDialog will always be shown as a seperate window (e.g. blocking, non-blocking, etc.) and the QWidget itself is the base-class. I.e. QPushButton, QCombobox are derived from QWidget too. In my opinion it would be better to use only one QMainWindow since it should be a central point of interaction/navigation for the user EDIT: I forgot to mention that also the UI-file has to be changed, i.e. by using a text-editor, change the line (4th row I think) <widget class="QMainWind

How do you change the namspace of a vb.net form with a VS designer partial class?
You can modify the namespace in the designer file e.g. Form1.Designer.cs. As long as you do not change the code within the Windows Form Designer generated code region, you should be fine. Another option is to create another folder in your solution. After adding a form to the new folder, its namespace will automatically have the name of the folder appended to it.

Shown handler in Form's base class in the way of designer
Some events are fired in the designer as well, it is what gives the Winforms designer its wysiwyg ability. Notably Paint, Shown is also fired, etcetera. The DesignMode property is provided to allow you to tell whether your event handler is running at design-time. Fix: void BaseClass_Shown(object sender, EventArgs e) { if (!this.DesignMode) { Close(); MessageBox.Show("This cannot be opened."); } } Do note the flaw in your approach, this event also fires for a derived form. You might be helping too much.

JFrame class convert to a NetBeans Designer support JFrame class
First of all, Eclipse does have a Swing UI Designer Tool indeed. It is call WindowBuilder Pro and you can update your Eclipse to include it easily. The manual is here. WindowBuilder Pro is very stable and runs on any platform Eclipse supports. It may not be as well integrated to Eclipse, as Matisse GUI builder is in Netbeans, but you can do your development without any problems and limitations with both. You can do almost anything with both plug-ins. Both are flexible and expandable if you learn how to work with them. Conversions of Swing applications between Eclipse and Netbeans are not very easy. You have to select one environment and stick to it. GUI builders do not substitute basic Swing knowledge. It is always best for beginners to write their Swing code, using a regular editor

Java Serialization for Extended Class
Since super class doesn't implement Serializable contents of the super class wont get serialized. Only the contents of the subclass would get serialized. When you deserialize the default constructor of the superclass would get executed and the fields of the superclass initialized as if you invoked the default constructor. Following example illustrates this. public class SerializationTest { public static class Base { private String name; public Base() { this.name = "johnDow"; } public String getName() { return name; } public void setName(String name) { this.name = name; } } public static class Sub extends Base implements Serializable { private static final long serialVersio

You don't need to explicitly declare the properties. Just make sure the names match.

Boost::serialization and boost::mpi to broadcast derived class via base class pointer
I was thankfully able to answer my own question (I think.) Boost doesn't handle through-base-pointer serialization properly when combined with boost::mpi::packed_skeleton_iarchive. The solution is then to use a different kind of archive, e.g. text_iarchive/text_oarchive, instead. For example, to broadcast: std::ostringstream oss; boost::archive::text_oarchive oa(oss); oa << value; std::string s = oss.str(); boost::mpi::broadcast(comm, s, root); And to receive: std::string s; boost::mpi::broadcast(comm, s, root); std::istringstream iss(s); boost::archive::text_iarchive ia(iss); ia >> value;

How to achieve dynamic partial XML class serialization in .Net?
The code below may solve your problem. We create a serializable class called MemberList, that contains an array of MemberCodes. After your list of member codes is populated during runtime, we convert it to an array and serialize it into XML. The results will be saved to a file called "test.xml" in your debug folder. XML Output <?xml version="1.0" encoding="utf-8"?> <MemberList xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <Members> <Member>Field1</Member> <Member>Field2</Member> <Member>Field3</Member> <Member>Field2</Member> <Member>Field1</Member> <Member>field4</Member> </Mem

How to exclude class fields from serialization by XmlElement name?
Have you encountered the [XmlIgnore] attribute? Adding it to members of your class will exclude them from serialization. So, for example, you can replace [XmlElement("Surname")] with [XmlIgnore], and then your serialized agent will look like this: <Agent> <Name>John Doe</Name> </Agent> Alternately, if all you really want is just <Name>John Doe</Name>, you could write a wrapper class: [XmlRoot("Name")] public class NameElement { [XmlText] public string Name { get; set; } } * EDIT * While it's possible to generate such wrappers at runtime, it's difficult, inefficient, and not very practical. To do so, I guess you could reflectively examine your object and find the properties you want (root.GetType().GetProperties().Where(p => /* yo

Protobuff.NET - different serialization of a abstract base class
Add, to the base-class: [ProtoInclude(1, typeof(ClassB))] Basically, as with XmlSerializer (see: [XmlInclude]) and DataContractSerializer (see: [KnownType]) - the serializer needs to know about sub-classes in advance. The easiest way to do this is with attributes, but it can also be specified at runtime if you prefer. Note the 1 here is just any key (preferably a small number - they encode more efficiently) that doesn't conflict with other keys in ClassA (so: I couldn't use 2 because A is 2 in ClassA1). Keys only need to be unique within the single class (not between different classes, even in inheritance).

Error when opening designer on inherited form
You can clearly see from the stack trace that your base form's Load event handler is running and throwing an exception. This is normal, events in the base form like Load and Paint run at design time as well. It provides the WYSIWYG designer view. This however goes poorly if that code can only work properly at runtime. The Control.DesignMode property was meant to provide you with a way to check if the code in the the class is operating at design time. Unfortunately it is not available in CF so a different approach is needed. The magic incantation looks like this: private void frmBase_Load(object sender, EventArgs e) { if (this.Site == null || !this.Site.DesignMode) { // Not in design mode, okay to do dangerous stuff... this.UpdateOnline();

ASP.NET Designer.xx generates 'already contains a definition for' control error
It sounds like something is trying to add duplicates of your controls to the designer file. VS updates the designer file on every edit you make which is why it happens as soon as you edit the aspx or ascx files. One thing you can do is when the error is thrown, open your designer.cs file and check--my bet is that you will see duplicate declarations. If this is the case, it is probably a bug in whatever library you are using--though I couldn't know for sure without some more information. Delete the duplicates and you should be able to build again. As far as keeping it from happening again, we need to see what is being generated in the designer file.

Boost serialization over dereferenced base class pointer
I met the same problem with you! So I looked over the doc of boost,which give a way to solve the problem,I can define a class D to manage the derive objects,and use the ar.register_typeto diff the a b c class,just like this: class base { ... }; class derived_one : public base { ... }; class derived_two : public base { ... }; main(){ ... base *b; ... ar & b; } When saving b what kind of object should be saved? When loading b what kind of object should be created? Should it be an object of class derived_one, derived_two, or maybe base? It turns out that the kind of object serialized depends upon whether the base class (base in this case) is polymophic or not. If base is not polymorphic, that is if it has no virtual functions, then an object o

You probably don't mean to use polymorphic_xml_archive (see docs). Notably, polymorphic archives have to do with the interface of the archives, nothing with the entities you're serializing for (they can always be polymorphic). If you use xml_archive instead, the problem vanishes.

Is it possible to serialize transient field of the class using my custom serialization or using Externalization?
The answer is yes if you are using the custom serializaton. When we do custom serialization by overriding the writeObject method, you take control of the serialization and can do whatever you want. So you can also assign or use a value of a transient field and can also marshall it along with other class attributes.

JSON/XML serialization: Ignore/include some fields from the base class
You should use a DTO that is specific for your current action and then copy the data from the DTO to the actual object you want to use. Benefits of this is you can define validation that are specific to this action and you'll have no attributes on the business object. You can use different validation rules per action for each new DTO and still use the same business object. If you don't want to write the mapping code to map from the DTO to the business object you can use AutoMapper. Example code: public enum ColourType { Flat, Metallic } public class Car { public void Repaint(int red, int green, int blue, ColourType colourType) { // TODO: Add some validation logic and business logic. } } public class RepainInMetallicModel { [Required] [Range(0, 100)] public int Red

Boost serialization with shared_ptr without implementing serialize() function in pointed class
The reason i want to use a shared_pointer is to avoid defining this function for some of my complex classes. In my opinion, this is a wrong reason to use shared pointers. Using shared pointers is good, but the reason is that it does memory management for you, so that you do not have to call delete yourself. In some (rare) cases, using smart pointers may not be the best solution and you would prefer to do memory management yourself. This is the most important criteria to decide to use smart pointers or not, serialization being a side benefit/trouble comes after. Anyway: I am not an expert in the boost::archive framework, but it seems serializing to the class Archive is more subtle than just printing the value, since it also uses a "version" in case you want to change how you seriali

Unsolvable (as of yet) serialization error
Without seeing any of the code, it's difficult to troubleshoot. However, we had something similar that was caused because the DataContractSerializer expected a specific type (as defined in the service interface), but was instead getting an EntityFramework proxy type. We decided to use the Data Transfer Object pattern to resolve this. We created base classes that were simple data transfer objects. EF-aware classes inherit from these and add persistence-related logic. These DTO objects implement ICloneable (or something similar) which allows us to easily create data transfer copies of the Entity Framework proxy classes before sending objects to the serializer at the service level. It may also be possible to resolve this by creating a custom serializer that has knowledge of Entity Frame

Serialization Cryptography Error
Crypto is somewhat complex. First get the crypto working, just the crypto. Start with a piece of text: "I wandered lonely as an armadillo." Use your code to encrypt and decrypt that text, forgetting about the serialization. When that is working correctly then, and only then, use your working crypto code to encrypt/decrypt the serialized object. Have you successfully serialized/deserialized your object without any encryption? On a brief glance, you need to set padding to PKCS#7 (aka PKCS#5). Your PaddingMode.None may be what is causing the problem. Without padding your final block may not be being processed correctly. Obviously you need to use the same padding for both encryption and decryption.
