Ok, my bad here. Disregard my previous mail.

The operator << evaluation happens from left to right. But probably,
the compiler evaluates all parameters in the line first from right to
left, then applies operator <<.

Perhaps other people can help here, interesting question.

The statement evaluation happens from right to the left, like all
others. But the ostream operator << acts like a stack. You evaluate
expression from right, push. Then at the end, everything added is
popped.

So basically, you push 512, 256, 128. Then you pop 128, 256, 512.

Dear Friends,

I observed an irregular (I think) comportment of 'std::cout'
reproduced by the simple test code below:


#include <iostream>
using namespace std;


int myFunc();     // simple test function prototype


// test program
int main()
{
   cout  << myFunc() << endl           // this block results
         << myFunc() << endl           // in an inverted
         << myFunc() << endl << endl;  // console output

   cout  << myFunc() << endl;          // this block results
   cout  << myFunc() << endl;          // in a correct
   cout  << myFunc() << endl << endl;  // console output

   system("PAUSE");
   return 0;
}


// simple test function implementation
int myFunc()
{
   static int i = 1024;
   i /= 2;
   return i;
}


The console output for this code is:


128
256
512

64
32
16

Press any key to continue...


The questions:
The two 'cout' blocks act in a different manner! (?)
Why the first chained block results in an inverted output?
Does not the insert operator '<<' act from left to right?

Obs.: I'm using
      Dev-C++ 4.9.9.2,
      Win XP 5.1,
      g++ (1/29/2005).


TIA,
Franco Brancaccio

Hello all,

I am trying to understand on how to make a data
structure thread safe. I will use a simple example to
explain my problem.

Consider a class Array which encapsulates a 1d array
with the following definition:

<code>
class Array
{
public:
    ...
    ...
    int& operator[](int index);
    ...
    ...
};

Array A(10); // a 10 element array
</code>

This array A can be accessed by two different threads
simultaneously - one thread could be reading a[5], and
another writing a[5]! How to protect my array from
such read/write conflicts? I am looking for a solution
which enables a user of the array class not to bother
about such conflicts. Is such a thing possible? If
yes, what is it?

Thanks and regards,
Siva Chandra

Hi....
=20
=20
I was wandering how to disable a BUTTON on a current window during runtime =
in Dev-C++;
=20
For example:
=20
I create a window that ask you for your e-mail address.
I also create a button that when clicked it should disable itself.
=20
If you input your e-mail in the current given textbox and then hit submit,
then the submit button disables automatically until you close the program.
=20
How do i do that?

Sorry,

it's possible to have only the last counts in output and not the entire i=
plementation of the wovels?

thanks

Interesting.

You are interested in double indirection without knowing why.

All your questions sounds exactly like the kind of questions you have to
answer for a school assignment. Are you per chance trying to avoid doing
your school work?

Don't reply to me - reply to all, or at least to the list.

Still html mail. Notice below what my mail client does with it. Very, very
easy to read...

You are also still claiming that Infobuf is a buffer. No, it is not. It is
a pointer. A pointer doesn't store data. It stores the address to data.
Notice that the LP in LPSOCKADDR stands for Large Pointer.

The next funny thing is that the last parameter you send - then one that
on input should specify the size of your buffer, and on output should
contain the actually used size - is an int pointer. And you called it Buf.
It should be an int variable, or more specifically a socklen_t variable.
It should be named something like buffer_size. You should take the address
of it and send as parameter.

If the expected answer may be as large as a SOCKADDR, then you need a
buffer at least as large as a SOCKADDR. The address of this buffer (and
the sizeof() this buffer) may be used as parameters to getpeername().
Sending it an uninitialized pointer and saying that you can only accept an
asnwer as large as a pointer will never manage you to get any results
back. In this case, the OS is nice and catches your error. The OS could
just as well have killed your application.

This is an usage example - directly awailable from google. It is for Unix,
but the important concents are the same.

int s;
struct sockaddr_in server, addr;
socklen_t len;

// make a socket
s =3D socket(PF_INET, SOCK_STREAM, 0);

// connect to a server
server.sin_family =3D AF_INET;
inet_aton("63.161.169.137", &server.sin_addr);
server.sin_port =3D htons(80);

connect(s, (struct sockaddr*)&server, sizeof server);

// get the peer name
// we know we just connected to 63.161.169.137:80, so this should print:
//    Peer IP address: 63.161.169.137
//    Peer port      : 80

len =3D sizeof addr;
getpeername(s, (struct sockaddr*)&addr, &len);
printf("Peer IP address: %s\n", inet_ntoa(addr.sin_addr));
printf("Peer port      : %d\n", ntohs(addr.sin_port));

Hello Everyone.

Hope you will be good and fine.


Are the following declarations are same, and , if not than why, also i am n=
ew to double pointers, can you provide a simple tutorial on double pointers=
, why use double pointers(

Scenarios in which they used) and their benefits.

char **doubleList;
char *doubleList[];


Best Regards,

Muhammad Ammar

First of all - please avoid using HTML on the mailing list.

Second - you should send a pointer to a buffer to the function.

You are sending a pointer, but that pointer does not point to any
buffer... Declare a variable of the correct type and then use the
address-of operator.

Any body knows how to use:

I tried it and WSAGetLastError() always return to 10014.

10014 is:=20



Bad address.=20

The system detected an invalid pointer address in attempting to use a point=
er argument of a call. This error occurs if an application passes an invali=
d pointer value, or if the length of the buffer is too small. For instance,=
 if the length of an argument, which is a sockaddr structure, is smaller th=
an the sizeof(sockaddr).

Dear Colleague,

The use of computational procedures based on medical images to model and
visualize represented objects requires a high level of research =
investment,
due mainly to the strong demands of clinical partners. These procedures =
can
have different goals, such as shape reconstruction and visualization,
segmentation, motion and deformation analyses, registration, simulation,
etc. The main goal of this Mini-symposium is to promote the debate =
between
researchers involved in the related fields (Bio-medical Image =
Acquisition,
Analysis and Processing; Multi-scale Shape and Motion Reconstruction;
Multi-scale Modeling and Analysis; Scientific Visualization, Bio-medical
Software Libraries, Environments; etc.), in order to set the major lines =
of
developments for the near future.

If you are not going to use the MFC classes, don't bother with the Win32
API. Look at wxWidgets instead. The wxWidgets site has a lot of sample
code.

Thanks Younes. I think the program crashes when I use it along with
wxWidgets library (am not sure). When I tried the code alone it is not
crashing!

 Why do you say this? Do you know a better way for dynamically growing

Please - this has nothing to do with winsock. I repeat - this has nothing
to do with winsock.

You get a request.

The request contains a path.

You translate that path to something on the local file system.

You open the translated file name.

You send back the contents of that file.

You either close the connection, or - if you and the client supports
keep-connect - wait for more requests on the same connection.

Have you started by printing out all HTTP header information you get from
the client for different types of links?

Have you spent time reading the HTTP protocol standard?

There is no magic web folder to create. It is the web server (your code,
not winsock or any other transport layer) that makes the translation from
request path to local file system path. This can be a translation to a
local directory tree, but that is not a requirement. All requests can be
hard-coded to external files or to internal functions that builds
pages/images on the fly.

Not only must you process the request and figure out the path - you must
also make sure that the web server only serves allowed files, i.e. that it
can't be used to walk all over your computer, if the request contains ..
or drive letters. But this too is your job - not something to do with
winsock, or the server running on a Windows machine.

Have you read up on the HTTP protocol?

If your server claim that it users a modern version of the HTTP protocol,
then most web browsers will issue several requests on the same connect. If
you claim that the server only supports standard 1.0, then the browsers
will have to make new connects for each request.

There are no magic involved with winsock - your problems doesn't have
anything to do with winsock, but with understanding the HTTP protocol, and
what a web server is expected to do.

A client should not know anything about c:\Dev-Cpp\images - your web
server should have a defined root directory, and should figure out all
paths either based on that root directory or on individual path
translations.

You can also affect what requests the web browser makes by switching
between absolute, relative and fully qualified image names.

Some possible links you might have in the served document:
<a href=3D"http://<ip>/images/image1.gif">
<a href=3D"/images/image1.gif">
<a href=3D"images/image1.gif">

If you specify a relative path, then the client (the web browser) must
perform it's request relative to the main document. With an absolute path,
it is enough to use the same connect - or a new connect to the same
server. With a fully qualified URL, the web browser may connect to any web
server to retrieve an image.

the browser tries to download them, using the path http://youripaddress/
=20
I still can't figure out how browsers can download some data from servers w=
ithout sending any request.....
=20
Is there a way, USING WINSOCK2, to let the browser know that http://youripa=
ddress/ is just, C:\Dev-Cpp\images\?
=20
A source code will help better than a plain answer.

Yes, every MinGW tool - on their own - will work in directories with
spaces and with file names containing spaces, but every caller - and
Makefiles etc - must specifically add break characters or quote paths and
file names. There is no real difference from when using them on a Unix
machine.

Do thank the installer writer for stopping you from installing the tool in
directories that doesn't work.

Command-line tools normally uses space as separator between file names -
not as a valid character inside directories and file names. To use gcc or
make or the other tools, every single file/directory with spaces must
either use a break character before the spaces or put the names within
quotes.

Whenever you see special rules, you should always stop and spend some time
figuring out _why_ they have spent extra time adding these special rules.
It would have been a lot easier for them to accept any characters at
all... However, a lot of MinGW and/or Dev-C++ users would then have been
very, very sad and complained.

My best guess is that it's not the installer engine that's the problem.

I don't have much (okay, any) experience with MinGW outside of DevCPP but in
my experience paths with spaces muck up a lot of things.  I would guess the
installer is smart to not let the user install to a long path name because
of limitations with either the compiler or one of the other tools associated
with it.  It's also just good practice on the Windows platform to keep it
simple whether or not you have any intention of later using any legacy
tools.  But I'm with you on never installing anything at the root of
%systemdrive%.
