Re: [Dev-C++] moving to 3d programming

[Daniel G. <sp...@ho...>]

DirectX is used by many many people and organisations. Microsoft recently 
removed themselves from the OpenGL consortium (or whatever its called) as a 
side note.

I reckon DirectX is the way to go, you know 2D programming and Dx has (had) 
a 2D component, which is now part of Direct3D.

[Dev-C++] provision in Dev-C++

[vinay k <vin...@ya...>]

hello experts,
Is there any provision of using variable of type int64
in Dev-c++. Microsoft visual studio has that
provision.

[David M. <ci...@ya...>]

What I was more looking to point out was the password some
one uses to
access their accout could also be their e-mail account
password as well as
the password for other accounts. If you are able to retrive
the original
password you open alot of posibilities.

[dein_metzger <dei...@ya...>]

 Hi to the list.
 I use directdraw for 2d graphics programming.
 I am thinking about learning 3d graphics programming.
 What=B4s the better? opengl or direct3d?

 thanks in advance,

A file-system by itself does not potect anything. The access properties =
of
files and folders make sense only when you access them through the =
specific
OS. So NTFS can be read by other Oses, the same as ext2fs and other file
systems of GNU/Linux. When I couldn't login to Win2K in the past because
some application messed up the OS I did not lose my files. I =
reinstallled
Win2k without reformating the drive, I was getting my files to a CD and =
then
made a clean install (with formatting of the HDD).

The same things apply to all OSes including GNU/Linux. If you want to =
secure
your files against theft you have to encrypt them, either using a
third-party program or facilities of the OS.

NTFS in Windows 2000 and later provides the ability for encryption using =
a
key randomly produced for each account. Programs that reset the password
from the outside by deleting or editing some file (I do not know the OS
internals) have also aas a result that key to be erased so files =
encrypted
via EFS (the encryption part of NTFS) from that user account become
unaccessible.

Who knows if this hole is a wanted "feature" by M$? To turn a bit away 
from the subject: I doubt that the so famous nimda virus has found 
security holes. I think they were actually not holes, but backdoors left 
for M$, so that they can access your server anytime, without you knowing 
of it. Sometimes the virus writers find these backdoors, left by M$. 
Just read the EULA of Windows XP, you'll find strange things there.

Another thing might be, what if nimda was actually the creation of M$ 
itself? I mean, to scare some high guy. Of course, this is all fiction, 
but it is still starnge, that nimda's spreading algorithm was 
"incorrect", so it was spreading too slow. I doubt that a virus writer, 
who can write a so perfect virus, located HUGE security holes (or 
backdoors) would write an incorrect spreading algorithm. I don't know 
exactly how it worked, I just know that if it was written good, nimda 
would have infected ALL M$ servers.

Just my brain-foolishness...

Yup, reasonably new versions of Linux can read NTFS. from DOS (freeware,
untested):
http://download.com.com/3000-2094-10126096.html

You said NT locks the file as soon as it starts, does that extend to
driver-load time? I mean, by `start' do you mean the user-visible start or
the actual kernel load? If not, one could theoretically write a fake driver
that can access the file. I wouldn't be surprised if Windows had a hole like
that.

Re: [Dev-C++] (no subject)

[David M. <ci...@ya...>]

Not sure if this still applies but there is a SAM file
located somewhere in the system32 directory. Problem with
this file is not even an administrator can open it! NT
locks it down as soon as it starts (anyone got a NTFS
reader?)

Being able to get the old is worse because the user will
not notice that it has changed and a careful person can
make it so that no (or rather very few) other traces are
left. 

To make matters worse, many people re-use passwords (makes
it easier to rember)

[Dev-C++] Optimizing using the STL

[David M. <ci...@ya...>]

Any suggestions on how I can optimized the following
function?

void pc_char::write_to_all_pc(string to_send, bool
add_eoln)
{
  map<string, pc_char *>::iterator i =
current_players.begin();

  while (i != current_players.end()) {
    (*i).second->write_to_player(to_send, add_eoln);
  }           
}

I was hoping to use for_each but kept coming across the
problem of "How the hell am I going to pass the arguments
to write_to_player?"

Thanks in Advance

Try this:

Then read gcchelp.txt. This will have the contents of the help screens for

The array you're trying to delete[] is statically allocated. You cannot free
or delete[] or whatever it; it's part of the compiled executable itself. To
realloc()/free(), etc., you'll need to dynamically allocate memory.

Also, you mention that you're using threads. One good thing to do would be,
after delete'ing, NULL the pointer so that delete attempts by other threads
will not result in a page fault.

I was wrong, the file, like many others, are in subdirectories of 
/dev-cpp/, what I didn't know is that some files are in /lib.

Anyway thanks.

[Dev-C++] Deleting an array

[Christian W. <Chr...@vo...>]

Hi List,
 
 
ich want to write a component to share data (PVOID) between threads.
 
I have a class defined like the following:
 
class CDataExchange
{
    Public:
        stuff....
    private:
        PVOID pDataArray[1000];
};
 
 
in the AddData member I look the number of entrys and reallocate memmory for
that pointer
 
realloc(pDataArry[n], nDataLength);
 
 
that works (i hope)...
 
 
but if i try do delete the class, it will throw an exception.
 
In the destructor I do delete [] pDataArray; , with LocalFree() it is the
same.
 
Does anybody has any hint for me ????
 
 
Thanks in advance
 
 
Christian

You are going to get at least 10 replys to this mail, but lets begin :)

So, the compiler, what Dev-C++ uses, is the GNU Compiler Collection 
(formerly known as the GNU C Compiler). To get info on the compiler 
itself, visit
http://gcc.gnu.org

But you will likely won't get too much info from there, as that is the 
core homepage of GCC. GCC has been ported to many platforms and 
architectures, including Windows. To get info about the Windows port, visit
http://www.mingw.org

MinGW stands for Minimalist GNU for Windows. You will find everything 
you need there.

Oh, and the gcc command line help is: "gcc --help" (double '-')

Hope that helps.

[Dev-C++] GetFileVersionInfo

In Dev-C++ 4.9.8.0, it seems impossible to link to GetFileVersionInfo
and GetFileVersionInfoSize. After searching, those two functions are not
present in any of the .h files.
How to use them, or have the same functionality by other ways?
Thanks.

Yes but that in Windows XP/2000 SPsomething means that files encrypted via
EFS become unreadable forever. But that's OT here I assume. :-)

[Dev-C++] 32-bit compiler

[<and...@su...>]

Dear Users,

   I will need to point the path of a 32-bit compiler to run a specific
application.
   I will also need to compile some source codes from the /src app dir.
   Looking at c:\dev-c++\bin I saw gcc, g++, c++ and other executables.

   1-Where can I get information about these executables?
   2-In my application, I would preffer to run a command line compilation.
What
executable I can use and in what place can I get information (gcc -? and
g++ -?
don´t give the sintax)

Regards
Andre
