Actually, C++ is a high-level language too even if some have claimed the
precursor language C to be "high-level assembly" :)

Yes, it is possible to store binary data within the application. It can
bedone in a number of ways.

One common way is to use a little utility application that takes the
binary resource and converts to an array of hex data that is then compiled
into the binary like:

-----
// sound_cannonshot.cpp
unsigned char wavesound_cannonshot[] = {
  0x10,0x20,0x30,...
};
unsigned wavesound_size = sizeof(wavesound_cannonshot);
-----

Another approach is to store the sound as a binary resource, the same way
that Windows applications stores icons and bitmaps.

If using the resource file, then it is very easy to extract the data using
an resource editor on your executable. Even if the resource file is
compiled, the resource editor will display a list of all items in the file
- what type they are and what identifier to access them.

If storing the sound in the source, a normal tool can not extract it.
However, writing a tiny app that just feeds the full exe file through the
sound card may probably play the sound, unless the sound was incorrectly
aligned, i.e. the low byte of one 16-bit sample got played together with
the high byte of the next 16-bit sample, in which case it would probably
just sound like noise.

If it is every more important to protect the data, you can combine any of
the above methods - or the use of external sound files - with encryption.
Load file, decrypt, play. The openssl project contains readily available
code to encrypt/decrypt streams of data using government-approved
algorithms.

Alas, even with encryption, you will only be able to protect unmixed raw
sounds. The actual output to the sound card can normally alwasy be
retrieved, since the Windows sound system have a lot of layers where
third-party filters may install and rip the data.

Hello everyone.

My name is Philip Bennefall, I am an audio producer and game programmer =

Hi guys,

I'm using wxMemoryFSHandler to load in memory a variable number of images from 
a user selected location, resize them appropriately and display them in a 
wxHtml window.

All works fine, but once the html page is correctly displayed I need to clear 
the memory filesystem content. So I tried to do it looping on the files 
retrieving the first file name using FindFirst(), i.e.:

------------ CODE -------------------------
wxMemoryFSHandler* MFSH = new wxMemoryFSHandler;
wxFileSystem::AddHandler(MFSH);

// fill MFSH with the images and display them

......

// all works fine

wxString FileToDelete = MFSH->FindFirst("*");

----------- END CODE --------------------

Now FileToDelete is empty!! I tried also

MFSH->FindFirst("*", wxFILE);
MFSH->FindFirst("*.*");
MFSH->FindFirst("*.*", wxFILE);

but FileToDelete is always empty.

Any idea?

Thnks in advance.

For most operating systems, it is not necessary to delete objects before
the application ends. The OS will release all memory allocated to the
program.

However, it is strongly recommended to always release all allocated
memory. By being tidy, it is possible to run memory analyzers to inform
about potential memory leaks, i.e. memory blocks that the program forgets
that it has allocated.

1024x512 array doesn't allocate so much memory to give an error.
Do you get any error message?

By the way, if you declare a pointer using new operator, you must delete it
before the end.

Hello,

I had the same problem a while ago, as far as I remember I used new[] to 
get it working.
For example you could use something like that:

    float (*coeftemp1)[512] = new float[1024][512]; //not sure if this 
actually works

or you can use a one dimensional array:

    float *coeftemp1 = new float[1024*512];

and acces it the following way

    float z; //just for testing
    for (int x=0; x<1024; x++){
        for (int y=0; y<512; y++){
           z=coeftemp1[x*y]; //that way it should work
       }
    }

Of course if you don't use c++ you can use malloc. I hope this work, but 
I didn't test it.

Regards,
    Christoph

Don't try to statically allocate huge objects on the stack!

1024*512*4 is 2MB.

Depending on architecture, there are often a limited size the stack may
be.

Depending on architecture and compiler, there is also sometimes a limit to
how much the stack may grow for each function call - it depends on how the
compiler generats code to touch guard pages to let the OS allocate more
memory pages for the stack.

If you want a large array, either allocate it dynamically or create the
array as a global object.

Hi, There,

I want to declare a two-dimension array by 
"float coeftemp1 [1024][512];". It doesn't work. 

But, if I change it to "float coeftemp1 [1024][500];".
It works. Could any one know the reason?

Only think I can think may be there problem is NULL is defined in 
another way, eg Null or null.

Sorry, but I don't think there exists any cross compiler you may use.

Dev-C++ uses the MinGW compiler, which is a port of gcc for use on Win32
systems, and for generating Win32 binaries.

What exactly your problem is? What and how your doing things?
I had no problems with the Dev-packs earlier and I don't have them now, when I compile wxWidgets libraries myself.

Of course it doesn't.

Have you managed to initialize security to anything useful?

Are you thinking about flushing streams compared to other I/O in your
program?

By the way - is it possible for you to post in TEXT format?

The text copy of your mails have seriously broken indentation and line
endings (as you can see below), and not too many users like HTML-encoded
source code.

'Ello people.

I've got a bit of a problem now. See, I'm running WinXP, Dev-Cpp, with the
package compiled by Tor Lillqvist. But when I compile the program, I get an
error message saying "file shape.c: line 75(pango_shape): assertion failed:
(glyphs->num_glyphs > 0) aborting...". Now, I've googled around, but there's
really no decent answer and most of them hasn't really got anything to do
with GTK.

Excuse me if I've forgotten any parameter or detail or whatnot you need to
help me, it's just been a while since I've worked with this and I've
completely forgotten any details of matter.

Actually three lines - you need a close() too.

The C library have two separate sets o file functions. in io.h you have
the declarations for unbuffered I/O using file descriptors. It is common
to write int fd =3D open(...) to show that you are using a file descriptor,
as opposed to the windows code where the data type returned by
CreateFile() is called a handle.

In stdio.h you have the declarations for (normally) buffered FILE-based
I/O.

Note that some of the *stat() functions may retrieve the file size without
opening the file. The run-time library just retrieves the meta-data for
the file, and extracts the size without need to check if you have access
rights to the actual file data.

Are you building for a 32-bit or a 64-bit environment. In a 32-bit
environment, the standard filelength() or ftell() functions can normally
only report the file size of files less than 4GB large since they returns
the size as a long. Some OS have support for alternative functions
(ftell64(), *stat64(), ... with large-file support.

The file <dos.h> is an old include file introduced by some C compilers for
MS-DOS support. You do not want to use these functions. Either go for
functions defined in the ANSI standard, or if writing specifically for
Windows you might consider the Win32 functions.

#include <time.h>
time_t t;
struct tm tm;
t =3D time(NULL);
tm =3D *gmtime(&t);

If your library is reasonably new, you should use the thread-safe version,
where you supply the buffer for the tm struct:

#include <time.h>
time_t t;
struct tm tm;
t =3D time(NULL);
gmtime_r(&t,&tm);

Also, if you format the file name yourself, you should always generate the
numbers with leading zeroes, i.e.

snprintf(fname,sizeof(fname),"file_%04u%02u%02u.bu",tm.tm_year+1900,tm.tm_m=
on+1,tm.tm_mday);

Without leading zero, nov 1 and jan 11 would look the same:
file_2006111.bu

Hi!

First of all, as you have probably already realized, you can't directly
mix Win32 functions (they use capitalized names) with c standard-library
functions (they use lower-case names), so fopen may not be mixed with
GetFileSize().

Second, OpenFile() is an old compatibility function for 16-bit Windows.
Use CreateFile() instead. Despite it's name, it is used for opening
existing files (and sockets, serial ports, ...) too.

Sample code:

#define WIN32_LEAN_AND_MEAN 1

#include <windows.h>

int main() {
    HANDLE f =3D CreateFile(
        "filesize.c",
        FILE_READ_DATA|FILE_READ_ATTRIBUTES,
        FILE_SHARE_READ,
        NULL,
        OPEN_EXISTING,
        0,
        NULL);
    if (f !=3D INVALID_HANDLE_VALUE) {
        DWORD low,high;
        low =3D GetFileSize(f,&high);
        printf("Low =3D %u High =3D %u\n",low,high);
        CloseHandle(f);
    }
    return 0;
}

If you want to find a file size using just c-lib functions, you may open
the file, and do a seek to the end of the file.

FILE *f =3D fopen(...);
if (f) {
    fseek(f,0,SEEK_END);
    long pos =3D ftell(f);
    fclose(f);
}

Note, that for 32-bit machine, this only works for files less than 4GB.

You may also use any of the *stat() functions, which retrieves size,
attributes etc for a file.

#include <sys/types.h>
#include <sys/stat.h>

#if defined(WINDOWS)
#define stat _stat
#endif

struct stat s;
if (0=3D=3Dstat("calvin.txt",&s)) {
    printf("Size of file is %u\n",s.st_size);
}

Note that if you use a M$ compiler, they have decided to use non-standard
names for the stat functions. I don't know if it is to their way of
supporting Unicode, or if it is an attempt to make people avoiding them,
or if they want to make sure that Windows programs should not be too easy
to port to Unix and the reverse.

One important thing to do: Always check return values. You get a file size
of 4095 MB in your original code because the function returns -1, which
for a 32-bit processir is normally the same as 0xffffffff. Your division
then represents 20 shifts (1024*1024) to the right, and what remains is
0xfff, or 4095.

Most file functions - and wuite a number of other too - may fail because
of programming errors, lack of resources, lack of access rights etc.

Hi,

 

I have this piece of code which compiles on HP11i (HP11.11) machine but
throws error on HP Itanium (HP 11.23). 

 

#include<stdarg.h>

 

main()

{

  va_list ptr;

 

   if(ptr == NULL)

 printf("It works!");

  else

             printf("It does not work!\n");

 

}

 

The error thrown on itanium is: 

"rad.c", line 8: error #2041: expression must have arithmetic or pointer
type

    if(ptr == NULL)

 

What changes do I make in the code so that the code compiles on both HP11.11
and HP11.23? 

 

Regards,

Radhika

 

Hi to all,

does anybody knows if (and how) it is possible to add new servers in the list 
of the webupdate utility? I remember that in a previous version there was a 
text file containing the devpaks repository namesbut now in 4.9.9.2 version I 
can't find it. I would like to add the old.devpaks.org to the server lists 
because there are files not available in the new devpaks.org.

I know that I could download and install them "manually", but it's easier to 
do it through webupdate for a wide number of packs.

Thanks in advance.

Dear Colleague,

=20

It is a pleasure to announce the new International Journal for =
Computation
Vision and Biomechanics (IJCV&B) and its first call for papers.

=20

Actually the research related with simulation of biomechanical =
structures
has been a source of hard work in several distinct areas of science as, =
for
example, mathematics, mechanical, physics, informatics and medicine.

The numerical simulation applied to living structures is one of the most
promising areas of research. However, for its successful, several topics
related with geometric modelling, numerical modelling, biomechanics,
material models for living tissues, experimental methodologies,
mechanobiology, etc., and their application on Clinical Environments =
must be
developed and much more investigation is needed.

=20

The main goal of the International Journal for Computational Vision and
Biomechanics consists in the provision of a comprehensive forum for
discussion on the current state-of-the-art in these fields.

=20

It is an honour to invite you to submit your work to be published in the
International Journal for Computational Vision and Biomechanics. We are =
sure
that your published work in the IJCV&B will soon bring the Journal to a
desired standard.

For further details, including Aims & Scope and instructions for
manuscripts, the Editors invite you to visit the website of IJCV&B at:
