dev-cpp-users Mailing List for Dev-C++ (Page 47)

Hi,

  Does anyone have the experience of design slider control in Dev-C++?
  It seems I can only find MFC ways to do so.  Dev-C++ cannot invoke MFC?

Thanks,
Jessica

I see.......
=20
And yes Dev-C++ is way dead than what i though.
=20
I am a really big fan of dev-c++ because is simple and most of all is FREE.=
 If i could help with the update or recreating Dev-IDE, i would do it with =
no problem.
The thing is that picking Dev-C++ by oneself is kind of hard, is better to =
work with more people.=20
Maybe if there were lots of helpful hands Dev-C++ could become better than =
what it is now, supporting .NET framework and lots of other things.
=20
If you see sombody asking for help because that sombody wants to update Dev=
-C++, please tell me, i would help that person with no problem.
=20
Thanks anyways for your help.=20

Hello guys

I am in face of a little problem. Im building one client to some log server.
This server use UDP as the datagram family. I have a lot of commands i must
implement in this application, and i like the responses to be done in
another connection (New connection from my connect function). In winsock2,
how can i retrieve the CLIENT port number and IP? I need this information to
ass to the master server this address, so he can send this information
there. I just need to complycate everything so much becouse i like to work
in route environments, without look for a nat in this router. If the
connection comes from the client, the server can use this same connection to
delivery the log output. My problem is quite simple, instead. Can i ask to
the other server, or is in some part of the pack sent/received, or somewhere
else, the information of what port i use in my system to connect to the
remote server? And what is the ip i am using (outside ip) without parse
websites html like whatismyip? I think all this information is in the
packets, but i cant figure out how to read that information.

Thanks in advance, and sorry for my poor english.

DevC++ is an IDE.  You're asking if there's a way to build a ribbon
using a non-MS GUI building API.  And yes, it's possible, though it'd
probably have to be handwritten.

A ribbon is:

to replace the menu bar with something called ribbon.

First of all - if I was you, I would immediately rewrite the functions to
take parameters. Globals for parameter-passing is WRONG. W.R.O.N.G. You
most definitely don't want such a solution. For a school work, you would
not pass. For a commercial work, you would get huge support costs. For
private stuff - no reason why not do it the correct way!

Second: My suggesttion does handle multiple files including the same
global.h file, and takes care of the extern keyword in a reasonable way.
Having multiple source files calling functions from multiple other source
files is how most software is written. Either write one header file for
each source file, and let each source file include all needed include
files. Or, if the project is small, add all function prototypes to a
single include file.

But make sure that you immediately drop any globals for parameter passing.
Yow will you ever remember to give all global variables an initial value
before calling a function? With parameters, the compiler will complain.
With globals, it will not know!

You're asking whether Direct3D is better than OpenGL.  I don't know,
but I do know that in every NVIDIA technology demo to date, OpenGL has
been the renderer of choice for demonstrating the next generation of
graphics features that haven't been seen yet.

I know that the latest NVIDIA demos have been done in Direct3D 10,
however, that's mainly showing that D3D isn't just a toy language.

I'd pick OpenGL, because it's cross-platform, fast, and need I mention
fast?  In addition it won't lock you down to the Windows platform in
the way DirectX will.  Need I mention that OpenGL won't lock you down
to one version of one platform the way D3D 10 will?

Thank you!

   But, I forgot to tell that:
The "other.c"-type files also make
references to the global variables and
they also call functions that belong to
other "other.c"-type files.

In other words:
///main.c///////
#include "global.h"
main()
{
    func_1();
    a = 100;
    func_2();
    func_3()
    ...
 }
///module1.c///////
 extern int a;
 extern int b;
 extern int c;
 func_1()
 {
    a=300;
    ...
 }
///module2.c///////
 extern int a;
 extern int b;
 extern int c;
 extern func_1();
 func_2()
 {
    a=300;
    func_1();   // see this!
    ...
 }
///module3.c///////
 extern int a;
 extern int b;
 extern int c;
 extern func_1();
 func_3()
 {
    a=300;
    func_1(); // see this!
    ...
 }
///global.h///////
int a;
int b;
int c;
void func_1(void);
void func_2(void);
void func_3(void);
/////////////

   Yes, I could improve the flexiblity of these functions
using parameter-passing. But, is there anything that I
can do to avoid these "extern" declarations in the modules?

Andre

Dear users,

   Please consider the following project-file
cenario:
///file1.c///////
#include "global.h"
main()
{
   func_x();
   a = 100;
   ...
}
///file2.c///////
extern int a;
func_x()
{
   ...
   a=300;
}
///global.h///////
int a;
void func_x(void);
///////////

My problem is:
   1) I have a lot of file2.c-type files (files with only
      function definitions), a lot of functions
      and several "extern" variable declarations;
   2) Trying to include global.h in file2.c too, avoids
      the need of declaring all extern variables. But this
      action generates warnings of duplicate includes (2 or
      more include global.h);
My question is:
   Is there any way to manipulate several file2.c-type files
without declaring each extern variable?

how do i install GLUI in Dev-C++?

I installed one from Dev-Pkt..but it seems it doesn't work properly.

is there anybody here can provide me good website to download GLUI?  and do
you have the installation instruction?

i need it urgently, because of the deadline of the project.

thanks in advance.

Hi,

First, please be courteous and clear in your messages:
Say hello, and ask for help, instead of just sending code and an error.

Second, please indent your code, or many people will not even try to read it
(plus it might make you find the problem!)

int main(int argc, char *argv[])
{
  int i,j; //Dilwsi metavlitwn//
  i=1;     //Arxikopoiisi metriti i//
  while ( i <= 5){ //Vrogxos epanalipsis//
    printf("\n");
    for(j=1; j<=i; j++)
      printf(" %d ",i); //Emfanisi apotelesmatwn//

    i= i+1; //Ayksisi counter//
  }
  system("PAUSE");
  return 0;
}

Third: comments don't need to end with a // (but it doesn't do any harm)
You were probalby thinking of /* comment */, where comment can span multiple
lines if you want

Last, I'm sorry, it compiles just fine here, and runs with the following
result:
1
2 2
3 3 3
4 4 4 4
5 5 5 5 5 Press a key...

Good luck,
Jonathan

  So..this is my code for example



#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
  int i,j;       //Dilwsi metavlitwn//
i=1;                   //Arxikopoiisi metriti i//
     while ( i <= 5){          //Vrogxos epanalipsis//
   printf("\n");
     for(j=1; j<=i; j++)

printf(" %d  ",i);        //Emfanisi apotelesmatwn//

i= i+1;                   //Ayksisi counter//
}
  system("PAUSE");
  return 0;
}
and this is the result
 C:\Dev-Cpp\Makefile.win [Build Error]  [main.o] Error 1

Hi..I have already install the 4.9.9.2 version but when i try to compile a
single programme the compiler shows many notifications about the #include<
stdio.h>.
Is there any problem with the interoperability between Vista and DevC++?
Thank u!

Hi my friends,

  I'm newcomer and have a little question.

  I need insert into my software a feature of 'navigate' into a file tree
and I need to know what API's to use. I have got a sample code but operating
with Borland API's  :-(
  The logic is simple. I need open and read all files of some tree. Thanks
!!!!

here http://www.pcre.org/  might help

Hello,

I would like to know if someone here is familiar with pcre.h?
And if you know where can I find the version for DOS or Windows?

Thank you

OK.
I 'supposed' it was an intrinsic compiler feature.
But nothing better than a detailed explanation given by an expert!

I guess, the better strategy is to use 'separate-cout' statements in similar
situations.

Thanks,
Franco

Elaborating a bit more on the problem. The C/C++ compiler is free to
evaluate function parameters in any order. In the case of gcc/g++,
function parameter evaluation happens from right to left. Also, all
parameters have to be evaluated before function call.

The function:

--- ostream &operator <<(ostream &, int)

acts just like:

--- ostream& write(ostream &s, int i){ s.write(i); return s; }

Thus, this statement:

--- cout  << f1() << f2() << f3();

is equivalent to:

--- write3( write2( write1(cout, f1() ), f2() ), f3() );

because the << operator is evaluated from left to right. I renamed
functions to make it easier to explain (write1, write2, write3 are the
same, like f1, f2 and f3).

When compiler sees this, it:
1- evaluates write3 right parameter, f3r = f3().
2- evaluates write3 left parameter, write2( write1(cout, f1() ), f2() ).
    2.1 - evaluates write2 right parameter, f2r = f2()
    2.2- evaluates write2 left parameter write1(cout, f1() )
        2.2.1- evaluates write1 right parameter, f1r = f1()
        2.2.2- call w1r = write1(cout, f1r)
    2.3- call w2r = write2(w1r, f2r)
3- call write3(w2r, f3r)

So, the f functions will be called in the order: f3(), f2(), f1()
before any of the write functions due to parameter order evaluation.
The write functions will happen in the order write1(), write2(),
write3().

As a result, the f functions will be called in reverse order, but the
stream will be written in correct the order. The side effect of the f
functions are responsible for the weird result you see. If a function
has a side effect on itselft, you can not rely on the order of
parameters if its called multiple times as parameters, since each
compiler is free to evaluate parameters in any order.

Sorry for bringing this up again, just wanted to clear it up.

I have no idea, really, however, I do know that it was either the
Boost C++ Libraries or the STL which gives you smart pointers, which
automatically deallocate their memory when there are no more
references to them in scope.  I think it could be possible to
implement a similar technique to memory locking to prevent thread
collisions.  However, I've never done anything like that in C++, and
am just going out on a limb here.  That's the sort of approach I'd
take assuming that it's of the utmost importance that the user of the
class need not pay any attention to thread locking/unlocking and
rubbish of that sort.

Hi,

You will need to use a mutex (as in mutual exclusion). Only one 'person' can
have control of it at one time.
Your operators should all try to acquire the lock on the mutex before
doing anything, and release it once they are done. You should also
take care to not segfault while holding the lock, or you will never
release it.
I am not familiar with mutexes in C++, only Java so I cannot tell you what
class to use but I'm sure a quick google will yield satisfactory pointers.

You might also want to provide lock/release methods for the whole Array, in
case a thread wants to have exclusive access to the array itsself. (eg. for
sorting, etc)

Cheers,
Jonathan
