Microsoft Document Explorer - VC ++ 2005 [英] Microsoft Document Explorer - VC++ 2005
问题描述
* back *和* forward * butttons不起作用。有人注意到这个吗？
我知道这是一个测试版，但即使是测试版，也很难
相信
Microsoft执行任何真正的质量控制.... *帮助*非常重要。
帮助功能主题组织严密。存在歧义和
背景障碍。主题标题具有误导性，并且假定用户的知识很多。例如，*托管代码经常被提到
没有链接到这个主题。此外，由于我使用的最后一个版本是6.0，当我遇到一个新的（与new（）不同）
运算符时，它对我的系统感到震惊（现在我觉得很老）插入符号（^）表示对象的句柄。 2005
看起来很像将Java程序员转换为C ++的尝试。我们现在有了一个很棒的新C ++，带有垃圾收集，接口实现，
超类定义。哎呀，我没有注意到，是否有一个延伸关键字
派生类？我很害怕Java迷们会想念这个。 IDE
太乱了，太复杂了 - 它只是越来越难以使用，而且b $ b更难以使用。很快就必须成为一名火箭科学家才能使用
C ++ IDE从不介意学习它！从好的方面来说，不必像以前一样做这么多的编码，但新编译的C ++程序比
蜗牛慢。
哦，它是免费的，所以毫无戒心的学生会习惯它 - 疣和
所有并期望在工作场所找到它 - 好策略一次再次比尔!!
去微软!!!
The *back* and *forward* butttons do not work. Anyone noticed this?
I know this is a beta edition but even for a beta edition, it''s hard to
believe
Microsoft performed any real quality control.... *Help* is pretty important.
The help feature topics are very badly organized. There is ambiguity and
context disorder. The topic headings are misleading and a lot is assumed
about the knowledge of the user. Example, *managed code" is mentioned often
without a link to this topic. Also, since the last version I used was 6.0, it
came as a shock to my system when I encountered a new (not the same as new())
operator (now old I guess) caret (^) which means a handle to an object. 2005
looks a lot like an attempt to convert Java programmers to C++. We now have
a brilliant new C++ with garbage collection, interface implementation,
superclass definition. Oops, I did not notice, is there an "extends" keyword
for derived classes ? Java junkies will miss this one I am afraid. The IDE
is soooo cluttered and complicated - it just keeps on getting harder and
harder to use. Pretty soon one will have to be a rocket scientist to use the
C++ IDE never mind learn it! On the bright side, it''s nice not to have to do
so much coding as before but the new compiled C++ programs are slower than
snails.
Oh well, it''s free, so unsuspecting students will get used to it - warts and
all and expect to find it in the workplace - good strategy once again Bill!!
Go Microsoft!!!

我认为这是因为它是Beta并且文档经过重新设计。
2003中的当前帮助是可以的。
此外，由于我使用的最后一个版本是6.0，它对我的系统感到震惊当我遇到一个新的（不同于new（））
运算符（现在我觉得很老）插入符号（^）表示对象的句柄。 2005看起来很像将Java程序员转换为C ++的尝试。
我不同意这一点。句柄具有与通常指针不同的语义，我更喜欢这种方式，而不是托管扩展中的处理方式。 for C ++（VS 2002/2003）。
您无法对托管堆中的对象执行标准指针操作（如指针
算术），因此使用指针表示法作为在VS 2002/2003中只会让人感到困惑。
通过这种方式，不同的东西保持分离。

I think this is because it is Beta and the documentation is redesigned. Current Help in
2003 is OK.

I do not agree with this. Handles have different semantics than usual pointers and I like
it better this way, than what it was in "managed extensions" for C++ (VS 2002/2003).
You can not do standard pointer operations with objects in the managed heap (like pointer
arithmetic), so by using pointer notation as in VS 2002/2003 can only be confusing.
In this way different things are kept separated.

在.NET中，C ++是两个世界。无人管理的世界和管理的世界。在托管的
世界中，每个.NET功能都与非托管世界功能分开提供。

我认为这是因为它是Beta并且文档经过重新设计。目前在2003年的帮助还可以。
这给我带来了VC ++ 2005 - 你是否承认这是一个
问题，这个问题将被修复，即微软知道它吗？ br />
好的Ioannis，你可能是对的，但我按照我读到的文件：
开始引用：
声明托管堆上对象的句柄。
托管堆上对象的句柄指向整个对象。对象和
不是对象的成员。
有关如何在托管堆上创建对象的信息，请参阅gcnew。
在Visual C ++ 2002和Visual C ++ 2003中，__ gc *用于在托管堆上声明一个对象
。 ^替换新语法中的__gc *。
备注
公共语言运行库维护一个单独的堆，它实现了
a精确，异步，压缩垃圾收集方案。要正确地工作
，它必须在运行时跟踪可以指向此堆的所有存储位置
。 ^提供了一个句柄，垃圾收集器可以通过该句柄跟踪对托管堆上的对象的引用，从而能够在移动该对象时更新它b / b
。通过句柄选择成员（^）使用
指向成员的指针运算符（ - >）。
结束报价。
对我来说，当一个人使用^时，编译器会生成代码，因此它被用作*托管堆上对象指针数组的索引*
CLR用来管理单独的堆。
因此在这个意义上它不是一个指针而不能用作一个指针。因此，尽管
你声明* Handles具有与通常指针不同的语义* - 这个
仅适用于所有以前版本的C ++中的CLR，它是
与指针基本相同。奇怪的是，它被称为*句柄*
而不是* gc-index *。
在.NET中，C ++是两个世界。无人管理的世界和管理的世界。在管理世界中，每个.NET功能都与
非托管世界功能分开提供。

Where does this leave me with VC++ 2005 - do you acknowledge this is a
problem which is going to be fixed, i.e. Microsoft knows about it?
Well Ioannis, you may be correct but I am going by the documentation I read:
Start Quote:
Declares a handle to an object on the managed heap.
A handle to an object on the managed heap points to the "whole" object, and
not to a member of the object.
See gcnew for information on how to create an object on the managed heap.
In Visual C++ 2002 and Visual C++ 2003, __gc * was used to declare an object
on the managed heap. The ^ replaces __gc * in the new syntax.
Remarks
The common language runtime maintains a separate heap on which it implements
a precise, asynchronous, compacting garbage collection scheme. To work
correctly, it must track all storage locations that can point into this heap
at runtime. ^ provides a handle through which the garbage collector can track
a reference to an object on the managed heap, thereby being able to update it
whenever that object is moved. Member selection through a handle (^) uses the
pointer-to-member operator (->).
End Quote.
Seems to me that when one uses ^, the compiler generates code so that it is
used as an index into an array of pointers to objects on the *managed heap*
the CLR uses to manage the separate heap.
So in this sense it is not a pointer and can not be used as one. So although
you state that *Handles have different semantics than usual pointers* - this
is only true for the CLR for in all previous versions of C++, it was
essentially the same as a pointer. Strange then that it is called a *handle*
and not a *gc-index*.
In .NET, C++ is two worlds. The unmanaged world and the managed world. In
the managed world every .NET feature is provided separately from the
unmanaged world features.
所以我被引导相信。您的网页很有意义。我能把它视为理所当然
你陈述的一切是正确的还是我需要进行更多的比较
对其他来源？ :-)
So I am led to believe. Your webpage makes sense. Can I take it for granted
everything you state is correct or do I need to make yet more comparisons
against other sources? :-)
嗨John！
我认为这是因为它是Beta并且文档经过重新设计。当前
2003年的帮助还可以。

Help in 2003 is OK.
这让我想到了VC ++ 2005 - 你是否承认这是一个将要修复的问题，即微软是否了解它？
Where does this leave me with VC++ 2005 - do you acknowledge this is a
problem which is going to be fixed, i.e. Microsoft knows about it?
我可以不重复这个问题...
你有VC2005 Express Beta 2吗？ （版本beta2.050215-4400）
（MS下载的最新Beta2）
