While I have not seen anything from Borland (I really haven't looked), the
local Delphi SIG says that Borland has announced that the next version of
Delphi will be fully .NET compatible. The concern in the Delphi community is
that Microsoft will turn is back on .NET if it does not live up to its
promise and Borland will be left holding the bag.

C# is a C-style language (at least advertised as such) which permits to
do the basic programming stuff (which is not a bad thing), like VB.

And not only of memory management, and also you do not need garbage
collection with C++. Also in C++ it is better to avoid explicit memory
management and use standard library containers instead.

Lets start by explaining what .NET is. .NET is a framework which has a
Just In-Time Compiler like Java Virtual Machine named Common Language
Runtime. When you create programs and compile them, they are "compiled"
to some intermediate bytecode called "Intermediate Language". When you
execute the program, the program is compiled at run time by the CLR
engine and then it is executed. The main difference with JVM, is that
JVM supports only Java while CLR is open to support any language (and so
different languages can interoperate).

.NET provides an API for the CLR which the various languages can use so
as to write programs, and interoperate with one another. C# is a C-style
language (which is another matter of discussion how much C-style is, it
resembles Pascal too) which is restricted entirely to the abilities of
the CLR.


The ideal in programming is to write portable efficient code with the
system dependencies encapsulated in a small portion of the code only. In
the view of .NET, if you want to make your code able to be used by other
.NET languages, you can create a .NET interface to it.


The question if C++ is going to be widely used now that C# has arrived
is a joke, not because of language fanatism but of reality.
C# is not a system programming language. You can not write an Operating
System with it, it is a simple language among others in the .NET world.
You cannot do advanced tasks with it.


.NET, the entire Visual Studio 7 (including the C# compiler), 6 etc, MS
Office, Internet Explorer, Netscape, Microsoft Windows, Virtual Java
Machine, etc are *ALL WRITTEN IN C++*. This is natural, it could not be
done another way.


You can write a C# compiler with C++ but you can't write a C++ compiler
with C#.

This is because C# and C++ design aims are different. C++ is made with a
bias for systems programming (to write OSes etc) with design aims for
writing programs with the maximum space/time efficiency possible, while
C# design aims is to write simple applications.


Also C# is not a normally standardised language, so you cannot find
compiler for it at every system (from water machines to large
mainframes). On the other hand C++ is openly standardised and you can
find a compiler of it *everywhere*, and this will be happening also in
the future (consider for example HTML, etc and other open standards,
they will be always supported).
C# also supports only Object Oriented programming and this not
completely (it doesn't support multiple inheritance etc). If you want to
write a hello world program in C# you have to create a class.


This is the truth, i am not a language fanatic and probably i 'll learn
C# in the future too (which will be very easy after C++, since their
abilities are a subset) as also Java etc.


There is much hype around C# because MS wants to lock in programmers.
The same happens for SUN's Java, Borland's Delphi and other
non-standardised languages.


Read the following interesting article about silver bullets (the above
languages are advertised as panaceas):

I am aware of that.  But the problem *could* be fixed by GCC ensuring that
from the time it started until the time it wrote the result was at least
one second long.  It would NOT be the RIGHT place to fix it, but it WOULD
guarantee that the timestamps all differed.

The RIGHT place to fix it is in 'make', obviously, since it is 'make' that
is having timestamp problems.  Since 'make' cannot go to more accurate
timers (it must rely on file timestamps, which are OS specified), it could
use the "delay if I need to" method between each program invocation stage.
If it guaranteed that at least one second passed between each step, that
should fix most things.  It still wouldn't guarantee that the first step
was OK, since the file could have been saved, then make started, then GCC
run to completion all within one second.  To fix that, make would need to
perform the delay step *before* each invocation, not just *between* all
invocations -- that way it would delay before the first invocation,
allowing the clock to advance between the save and the running of GCC.

Oh, and while I'm on the subject of clocks -- keep in mind that staring at
a computer clock can keep it from moving.  In particular on DOS machines,
running a program that loops continuously asking for the time and
displaying it will cause the clock to lose several minutes per hour,
possibly more on faster machines.  A fast enough machine might be able to
stop it completely.  On DOS, reading the clock does lock out the update
interrupt, so if you read the clock enough, the update interrupt can't ever
get through.  This is the flip side to the problem I described earlier
about reading a clock that did *not* lock itself during read, which allowed
for having the value change while you were reading, leading to clocks
appearing to run backward and other atrocities.

In case you're wondering, the right (or at least better) solution (which
can only be implemented by hardware designers) is to double buffer (I
believe the hardware term is register, or latch, but I'm not sure) the
clock.  Allow the update interrupt to always be able to write into the
writable buffer.  Allow upper layers to always be able to read from the
readable buffer.  Whenever either buffer is unlocked (when either update
interrupt exits or upper layer read function exits), see if the other
buffer is also unlocked, and if it is, copy (latch) the value from the
writable buffer to the readable buffer.  Really fast readers could still
stall out the update process, but once the program went away, the clock
would properly update.  I suppose you could have a bit to signal that an
update is pending, so that you could block reader applications out until
you could get the latching from writable to readable done...

Oh well -- doesn't matter, since the PC hardware won't be changing any time
soon (at least in that regard).  Just passing on some painfully learned
knowledge about how clocks are not nearly as nice and simple as you would
think they are...

[Dev-C++] code compatibility

[<tam...@ms...>]

Hey guys I'm still real green when it comes to code and I'm trying to go =
a little deeper than just the basics so I check out this book by Michael =
Abrash called "ZEN of Graphics Programming."  He believes you should writ=
e all graphics in assembly language do to C's lack of compatibility from =
one compiler to another and then he writes this C program.  Of course it =
doesn't compile on dev.  Could anyone tell me what compiler it does compi=
le on and how maybe I could get it to compile on dev?

Thanks for any help anyone could give to this newbie.

RE: [Dev-C++] C#

[Ramana K. <ra...@my...>]

thanks rob! it's nice to hear stuff like that :) lol
for those who are interested:

The C# language is derived from C and C++, and it was created for the
enterprise developer who is willing to sacrifice a bit of C++'s raw power
for more convenience and productivity. C# is modern, simple,
object-oriented, and type-safe. It borrows a lot from C and C++, but it is
considerably different in specific areas such as namespaces, classes,
methods, and exception handling.

C# provides you with convenient features such as garbage collection, type
safety, versioning, and more. The only "expense" is that by default your
code operates in safe mode, where no pointers are allowed. Type safety pays
off. However, if you need pointers, you can still use them via unsafe
code--and no marshaling is involved when calling the unsafe code.
/.../
You are provided with a runtime environment by NGWS, the NGWS runtime. This
runtime manages the execution of code, and it provides services that make
programming easier. As long as the compiler that you use supports this
runtime, you will benefit from this managed execution environment.

Your guess-that the C# compiler supports the NGWS runtime - is correct.
However, it is not the only compiler that supports the NGWS runtime; Visual
Basic and C++ do so also. The code that these compilers generate for NGWS
runtime support is called managed code. The benefits your applications gains
from the NGWS runtime are

Cross-language integration (through the Common Language Specification)

Automatic memory management (garbage collection)

Cross-language exception handling (unified unwinding)

Enhanced security (including type safety)

Versioning support (the end of "DLL hell")

Simplified model for component interaction

Re: [Dev-C++] C#

[Rob <ro...@us...>]

The way I've heard it characterized by a few people I know is that C# is 
Microsoft's Java-killer of the week. I'm actually more interested in 
using Java for Java-esque tasks, if that's the case. It's becoming a 
fairly mature language, and C# is brand new (and married to Microsoft, 
presumably).

C# is no threat to C++, and even if it was, the skills one picks up 
while learning C++ are invaluable. Heck, learning C++ is even making me 
a better Python programmer!

ok, cool, so C# is interpreted? (and always will be? - i guess it has to be)
that is great news to me.
from what i read tonight (on the internet at various places) C# is designed

Hi !
In Dev-C++ 4.9.3.0, to include debug information into the binary file of a 
program,  make sure that "Tools->Compiler Options->Linker->Generate 
Debugging Information" is checked.

As for manuals I have found something on gdb at the URL:
http://www.delorie.com/gnu/docs/

once there look for "gdb 4.18"

In the meanwhile, just to get you started, I have included some very simple 
ideas in an html file which I've zipped and attached to this mail.

If you do it in C++, instead of a built in arrray use a vector of
pointers.

An example:

#include <vector>

// ...

using std::vector;

// ...

vector<void (*)(int)>fnPtrs(2, fn);
  
fnPtrs[1]=foo;

Always ask. That is why this list is for. Coders talking with coders. :)


> How do I create an array of function pointers?

Or better: void (*fnPtr)(int);





> I tried making an array like this:
> 
>     void *(*fnPtrs)(int)


This is a pointer to a function returning void * and getting an int.



> 
> Didn't work.
>

void (*fnPtrs[])(int) = { fn, foo, NULL };


Or if you cannot think that big, you can make things simpler:


typedef void (*p2f)(int);
  
p2f fnPtrs[]= { fn, foo, NULL };

It depends on what dword is, but it doesn't sound safe.

[Dev-C++] Array of function pointers

[Abhijit S. <mu...@gm...>]

Sorry for my repeated OT posts, but I don't subscribe to many lists because
they have too much of traffic, and poor little me has a dial-up account. Of
all the lists I do subscribe to, Dev-C++ seems to have the most
knowledgeable (and tolerant) people.

Having finished buttering you up, here's my question:
How do I create an array of function pointers?

I declare a function pointer as:

    void (*fnPtr)(int arg1) = fn;

I tried making an array like this:

    void *(*fnPtrs)(int)

Didn't work.

    void (*fnPtrs)(int)[] = { fn, foo, NULL };

Didn't work either.

Ultimately, I got frustrated and made an array of dwords:

    dword fnPtrs[] = { (dword)fn, (dword)foo, (dword)NULL };

This worked, without any warnings. Is this portable and safe? Is there any
other ANSI way of making an array of function pointers?

Thanks for any help.

I think you can search in Google itself. In the search box, type:

    http://lists.sourceforge.net/lists/archive/dev-cpp-users: foo

where foo is what you want to find and the part before the colon is the site
you want to search in. I'm not very sure about the syntax. Look up 'search
