    ...and all the java crowd say the same thing about .NET. Move on, nothing to see.

    Exactly Chris. I for one applaud the work your team does, and creating a separate Java home is another excellent idea which will be appreciated by most of us. To those of you who hate (or are frightened of) Java, please don't waste space in this forum airing your prejudices.

      It's slow... it chews memory like a beast.... it boosts productivity like a monkey eating a dog......... http://www.java.com/en/[^]... If you want your application to be slow and not very good, use Java.

        Huh, I don't know Java. But I don't think it's that bad. C# isn't too fast, too. But there are pretty much features in C# now I don't want to miss like (automatic) properties, WPF, LINQ, extension functions,...

          Java has many adnvantages over .NET and disadvantages as well - one of the most problematic (in my opinion) being not supporting value types, everything is object. But, you state that it chews lot of memory and is slow; having seen your latest articles do you have the courage to say that WPF and especially your code runs faster and with less memory than Java Swing GUI for example? P.S. I write in .NET also.

          Thanks, Georgi

          I don't know Java, tell me, which advantages has it? Not supporting value types of course is annoying, but this isn't solved very well in C#, too. You can't clone objects by default, they all have to implement ICloneable, which is not even generic!

            Dude, I am not sure you are familiar with value and reference types at all; it has nothing to do with ICloneable... As a GUI developer I may speak of the following advantages of Java Swing over .NET 2.0: Java is completely detached from the underlying OS - .NET is using Interop primarily; 99% of the controls are wrappers of their Win32 equivalents; you need to know Win32 API in order to create commercial controls. Let me mention that things are different in WPF - there is actual bridge which separates OS from the GUI. But still, WPF consumes lot of memory and is not the platform a company, which cares about performance, would choose on... That is my personal opinion of course.

            Thanks, Georgi

              I think is the main difference between value and reference types is, that if you write x = y and y is a value type, x contains a copy of y, while when y is a reference type, x contains a reference to y. To copy y, y is required to ICloneable. Is that false?

                  I'm not sure i'd agree; I've created a Office Fleunt Ribbon control library using nothing more than WPF, which i'm happily using in a commercial grade application, with no problems (http://www.codeproject.com/KB/WPF/ribboncontrol.aspx[^], see also CIRIP).

                  It's a new technology, and so not full optimised yet; hey if you want to moan about something *new* then why not have a go about the lack of an open and save dialog. I'm sure exactly the same was said of MFC, Swing, etc.

                  There are companies using it, admitadly few currently but growing by the day. Yes, performance is shocking until you learn how to use it properly and then it's more than fast enough. Companies in my eyes don't care about performance, they care about cost to produce something that does the job, and from my experience WPF reduces development time (after over 4-5 years of Windows Forms (and Java Swing for that matter) and only <6 months WPF programming).

                    perhaps a better example might be x = y y.a_property = some_value if (x.a_property == y.a_property) then referance type else value type

                        OK, but basically it's the same. So what did I understand wrong? It does have something to do with ICloneable, or not?

                          .. I mean compared to C++. I don't think it's too slow, I've never had problems with C#'s performance, but for some algorithms you need C++.

                            like what? Yes, i'd agree there is a slight performance decrease compaired to c++ but it's neglible.

                              referance and values types have very little to do with ICloneable... values types a guess are effectively implementors of ICloneable as x = y produces essentially a clone of x

                                It is obvious that you are not familiar (to be honest your guesses amused me pretty much :)) with Value and Reference types - you may try the following article (the first found one after search). http://www.codeproject.com/KB/dotnet/Primitive_Ref_ValueTypes.aspx[^] If I may advise you - you need read more about the basics of .NET such as Common Language Runtime (CLR), IL, value and reference types, etc. And do not be that arrogant:

                                  .net slower than java or java slower than .net.... I can justify java slower than .net with about 10 minutes of coding (and 30mins of java tools downloads). Please don't ask me too though, really don't want the hassel of downloading java stuff.

                                    OK, basically, they have nothing to do with ICloneable. But if you want to create a copy of a reference type, this type needs to implement ICloneable, whilst in C++, reference types can be both referenced and copied by default and you can define a copy constructor to change the copying process. I think this is solved much better in C++.

                                      I hope you realise that my post was meant to be ironic.

                                        At NJIT they teach java now. Luckily, when i had to take those programming classes, it was all c++. I have reason to be happy actually... it allowed me to more or less understand the class-less C language... which, when i got to my microprocessor class where we did alot of 68k assemebly... that i was able to see the logical connection from which the C language is derived... because Assembly is just a lower level obvioussly-class-less C where you program with just functions, ...well they call em subroutines... but ya... When i was in high-school i had a class that did both java and c++... it was in that class that my hatred of Java indirectly started... You see we used the free compiler and wrote all our code in notepad. But anyone that ever programmed in c# in visual studio knows... that the Ide is what really makes coding fun... all that intelli-sense and code designer and the form designer and the addins... Ohh the addins! :P... anyways... Debugging in notepad is a bitch... you gotta count the lines... Overall that's why c++ was more fun (cause we had that old visual studio... called vs6 or something... but the debugger was a godsend... double click the error and it goes to the line with the error... wow... and the error messages actually made sense over what devcpp gave you (which i used for my homework at that time... untill i learned about something called kazaa :D) Anyways when i was a sophmore or something i was like... i gotta learn a language that's fun and fast... for personal projects... i was thinking visual basic might be a good idea... i already knew that java was a complete pos that was slow and the forms looked like complete dog crap...well that was visual studio 2003 installed and i saw in the loading screen the icon for J# and C#... well first i thought... well i know some java, maybe i'd give it another try in J#... then i looked at a blank Form project and at the using statements and crap... and was like... ya maybe i'll just use visual basic.net.... And then i tried c#... at first i was completely utterly confused mind you... but the syntax i think was just nice... when i create my first object like with the "new" keyword and how all int objects could be easily and painlessly ".ToString"'d... well that was when i was in love :P Wow i still remember the first time i learned of the property syntax... before that i was like... how the hell do you "communicate with a class".... Or when i was writting a silly program to be as a companion to a game called "Raven Shield" that would work wi

                                        Which is why, having been accepted to both, I plan to go to Rensselaer Polytechnic. I've been using C++ since I was ten years old and I don't want to give it up for four years!

                                          .net slower than java or java slower than .net.... I can justify java slower than .net with about 10 minutes of coding (and 30mins of java tools downloads). Please don't ask me too though, really don't want the hassel of downloading java stuff.

                                          And in 45 seconds I can prove to you that native C++ with ASM optimizations will run rings around them both.
