I have a problem with the view "Model". I wanted to generate a Class Diagram of my C++ application.
But when I load my view model, there is white, nothing displayed.
In the option -> Modelisation -> Diagram -> General
The support of model is active.
I have use them
http://docwiki.embarcadero.com/RADStudio/en/Activating_UML_Modeling_Support_for_Projects
But they doesn't match
I haven't the windows Modeling Support, same at 1 minute on this video for checked my already project :
https://www.youtube.com/watch?v=LTpAAz3WkZk&t=4s
I've writing at the french provider they selling them, adn answer that :
UML Modeling isn't available with C++ Builder, on the Embarcadero IDE only the code writing with language Delphi is supported.

I am very much confused about the words Component and Library.
I know the components are tightly bound, unit of functionality and modularity, and so does the library. In both the cases, binding is done at compile time. So what features make them different?
These are just two different words. Traditionally, anything that contain a bunch of things/code you can use is called a library. A bunch of C math function put together can be called a math library. A .NET DLL that contains a bunch of classes is called a class library.
The word Component comes from RAD tools and it implies some sort of design time support.
For example, a Windows Forms Menu class is a class that contains code implementing its runttime behavior (which is to display the menu in a window), but it also contains code that support certain things inside Visual Studio so that Visual Studio can design the menu at design time. It also has code that defines its "icon" in Visual Studio's toolbox, etc. All these things work together so that you can just drag it around on a "design surface" to make coding easier.
If you use .NET, there is an Object class which is the root of everything, and then there is the Component class that have a few members related to design time support. You can take a look of the class members which should give you an idea of what a Component is:
http://msdn.microsoft.com/en-us/library/system.componentmodel.component(v=vs.110).aspx
MS also has an article that explains it a bit more:
http://msdn.microsoft.com/en-us/library/vstudio/0b1dk63b.aspx
Needless to say, people often call class library that contains a lot of "Component classes" as a "component library". But there is nothing wrong to call it just class library.
Hope this helps a bit.
I was reading about Struts1 vs Struts2 and the author mentions one of the point is
" Programming the abstract classes instead of interfaces is one of design problem of struts1 framework that has been resolved in the struts 2 framework. Most of the Struts 2 classes are based on interfaces "
COuld anybody please tell me , from a developer point of view , does we need to bother if the framework uses classes or interfaces .
Could anybody please help me in knowing why using Classes in a interface is not good .
Could anybody please help me in knowing why using Classes in a interface is not good.
That's not what's said.
See this SO question/answer, or search the web for "program to an interface". The nutshell version is that programming to an interface (when done correctly) allows us to use multiple implementations of that interface based on our needs.
Doing so allows us to test more easily, allow functionality we didn't necessarily think of when we wrote the original base code (within reason), and so on.
currently I have a fully working project in Eclipse using OOP. Now I want to creat UML diagrams Use Cases, Sequence Diagram, class diagram, package diagram with eclipse, does eclipse or any available plugin for eclipse allow this service
Try out ModelGoon UML4Java, it can build Class, Package, Commumication, and Sequence diagrams from existing Java code. Diagrams are also built by using drag and drop. The sequence diagram is very detailed.
This is what I do Eclipse 3.6 and my Java projects. Just a drag and drop from the package explorer to the class or sequence diagram. Really cool.
-broken link to image removed-
For usecases which are an UML object and not an Java object I drag and drop the usecases from the model explorer. I also sometimes create a class and add Usecase as stereotype. It means that my class diagram can have usecase which are related to a class. It does the job and pretty easy.
You can try HiberObject plugin. Also can use Jupe
If you are using Eclipse 6.1 then this could be helpful.
Are there any free tools in the market which support Objective C?
I use Argo UML and Violet UML for modelling on my Mac (Assuming you are using a mac). They are not great but they work.
If you want code generation that is a whole different issue.
Actually, one of the points of UML is to be language-agnostic.
If what you're asking is if any of the available tools supports Obj-C code generation: Googling, you can find some (commercial) tools that claim to offer Objective-C code generation.
It probably makes more sense to use XCodes built-in diagramming tools, which can be found in the "Design" menu. These are not, strictly speaking UML, but are quite similar.
Also, UML might not be such a good fit for designing Cocoa / Objective-C applications, because mostly you will use Model-View-Controller, into which a UML diagram doesn't offer much additional insight.
Actually, XCode 3.2 had a class editor that did what is being asked for. In Xcode 4.0 and later we can only use it for core-data related tasks which is a shame. I have a similar need as I have a team member that prefers diagrams to code.
I don't understand why it was removed. I'm hoping that I can find it as a standalone tool within the Apple Developer member center, but I don't have high hopes.
Worst case, you can download XCode 3.2, install it alongside 4, and use the editor within 3.2.
I have tried this very briefly. So long as you don't try to open the file under 4, I think it works, though I'd be wary of opening your 4-based project in 3.2.
Hope this helps.
Simple question really. No elaboration required.
I have found similar tools for Java, C#, C++ and other languages but not VB.Net.
Thanks
Unfortunately, I don't know of a plugin for StarUML that will generate VB.NET code, however, if using a different modelling tool is a possibility, Sparx System's Enterprise Architect will generate code in VB.NET (as well as many other languages).
Enterprise Architect enables you to
generate source code from UML model
elements, creating a source code
equivalent of the Class or Interface
element for future elaboration and
compilation. In particular you can
generate C, C++, C#, Delphi, Java,
PHP, Python, ActionScript, Visual
Basic and VB.NET source code. The
source code generated includes Class
definitions, variables and function
stubs for each attribute and method in
the UML Class.
Unfortunately, Enterprise Architect is not free nor is it open source, however, there is a full functional 30 day trial available, along with discount options for academic pricing (if appropriate).
If you're looking to stay with free and/or open source software, I think the closest for VB.NET code generation would be to use a couple of tools in conjunction with each other:
Dia is an open source, GTK+ based diagram creation program for Linux, Unix and Windows released under the GPL license. You can use this to create your UML diagrams. From there, you would use:
Project: CodeGen from Novell, which will take the UML diagrams saved/exported from Dia and convert them into skeleton C# or VB.NET code.
If you're prepared to look at a more "general purpose" code generator, this page:
Generators that build VB.NET
will give you a good starting list of tools that will generate VB.NET code.
