I have not depthen extremely on the subject, but CLR is more efficient
than JVM, at least the time it was designed (JVM may have adopted CLR
features since then). For example a program when run the first time on
CLR gets many of its parts compiled permanently to win32 code so at the
end the .exe is something like an hybrid between binary code and
bytecode. Also it is not restricted to one language but all languages
share a common hierarchy and can interoperate with each other. So you
pick e.g. C and another person Javascript and you can build a program
using both languages. The good in C/C++ case is that by default VC++ 7
does not produce bytecode but pure 32-bit exe (it is the only language
that can produce binary code in VS). When you produce pure binary code
it is called unmanaged code and when you produce bytecode your source
code is called managed. The other great thing with C/C++ in .NET world
is that you can create pure binary code (that is it runs outside the
virtual machine) so as to have the maximum efficiency and create a .NET
interface for the other languages to interoperate with your code.
The bad news is that VC++ 7 will not be so ANSI/ISO C++ compliant
(probably they do not care/want standard compliance a lot) but will be
more than VC++ 6. I had heared rumors during VS 7 development that VC++
7 will not support iterators thus entering useless almost all the STL
and template mechanism. But things may have changed since then (but i do
not think so). They had stated that "100% ANSI/ISO conformance is not a
goal". Anyway the important thing here is .NET and language
interoperation, what IDE one should use VC++, C++ Builder, e.t.c. is
personal choice.
VC++ 7 is now in reality visual since it provides ala VB IDE (ready
buttons e.t.c.) but it lacks a lot even from C++ Builder 5 which has
anything as a component (http connections e.t.c.). That means that you
will have to type a lot again to use the system extensions in VC++ 7.
This month is also to be released C++ Builder 6 from Borland which i
consider extremelly better for Windows C/C++ development. Also there is
going to be C++ Builder for Linux. In C++ Builder 6 you can create win
applications that compile both in Windows and X-Windows world using CLX
library. It is the same as it happens now in Delphi 6 and Kylix (Delphi
for Linux) and Collin has started creating the new Dev-C++ for both
X-Windows and Windows. in C++ Builder 6 you can create even X-Windows
looking applications running in Windows and in C++ Builder for Linux
Windows looking applications running in X-Windows.
In a few words, you create an application dragging components like
buttons e.t.c. on a form and the program compiles both in windows and
x-windows and looks the same.
You can download a trial version of C++ Builder at:

This sounds familiar. Another virtual machine and auto garbage
collector! :-)
Sorry if this is off-topic, just a thought: how different is this CLR
from JVM?
