[Jason H. <jas...@bt...>]

There is a way of doing it. Create a Dev-C++ project and call it =
whatever, but not the name you actualy want it to be. Then add the =
source file or files you want to it, and save it all. Then you can exit =
Dev-C++ (or just close the project) and go to the project file and =
rename it to what you want, and restart dev-C++ and load in the renamed =
project. You may also want to go into project->options and change the =
project name there. It should all still work, and to be honest I can see =
no reason why it would prevent you from doing it this way in the first =
place. I can understand why some other files cannot have same names, but =
the project file isn't one.

Maybe in future version this restriction will be removed. (please?)

Jason.

  I always use names like Simple for the project then simple_file1.c  I =
found that works better :)

  not sure how to sort it so both can be the same name though.

[Dev-C++] [Dec-C++]eof() function and type variable from file input

[carlos D. M. <cg...@wo...>]

Hi again:

I am writing a program for make a two weeks work in one minute, and it
will take me two months...
I have a .txt archive with various tables of diferent amount of rows,
and always five columns; I need a program which the first five data are
sent to a char * variable; the next 5*n values to a float [5] and write
them in other archive as I need them, after one data which is char *,
made by letters and numbers, being the first a letter.

Well: I try it writing what I must write but:
a) If I use while(!inputFile.eof()){
                       the body of all the instructions needed
                        }
                                When I run the program, immediately,
when it's the moment of reading the inputFile **the program has
generated an error log and it wwill be closed by windows**
 b)       If I try something like for(as many times as tables it must
pass) I find that it doesn't recognize the type of the data:
    The first is a while(inputFile >> charvariable); what i want do with
them; while(inputFile >> floatvariable); what I want do with them, with
the correspondent variable arrays with the suscripts and counters, etc;
and inputFile >> thelastcharofthetable);what I want do; Then I found the
program:
    b.1) ***generated error.log bla bla guauau****
    b.2) It considered all data as char, and soit did for every data of
the txt file the same, what I want for the first five words.

Are there any function hich lets the program know if the data from input
file is float or char or int and once known use that data for the
correct instruction? Or it is best to do it by hand, killing the
computer and suiciding myself?

I hope this is a problem for be console program, so I will be able to
write the program I think i will need write in the future. But I think,
that although the main are the windows programs, the console ones would
be good to have a good work.
Now I don't need that hard program and it would be very, very useful can
program some little consoles. And if I can write the program five
minutes and do what I need in three seconds (I don't worry very much now
about efficiency, I write for myself) and avoid do it by hand in weeks
of giant boring waste of time.

Thanks to anybody who can help.
Thanks to everybody who will find this message occupying memory, for
their patience.
Thanks if Dev-C++ 5 solve this problems(if it is really a problem of the
progran and not my inexperience) (And thanks either if not).

[David A. <kyo...@ya...>]

Hi!

This is my first post here
Just a very basic question, Today is my first time
using DevC++ and I want to make a project lets call it
ProA which contains a file ProA.c The program tells me
it is not allowed to add c files with the same name as
the project BUT I have some examples where this is
allowed.

How can I make a project "simple" with a file
"simple.c" in it. I am sorry but the help of the
program is not clear at all!!

Dave

Re: [Dev-C++] my delete function in my linked list

[Jason H. <jas...@bt...>]

The main reason was to avoid the use of *&, I personally believe that =
using reference to a pointer, in main(), is a bad way of doing things. =
Using a container (I believe) is representative of better design, =
although it does look silly in the case of it containing only one =
member. I find it easier to deal with the list that way, and by using =
abstraction and such you can help avoid coding errors. Of course if I =
was using C++ I would create a linked list object and have methods to =
work upon the container.

You could create a global pointer for the list, and by putting it in =
'list' namespace you can avoid exposing it to global scope. I can't =
remember the exact best way of doing it this way off the top of my head =
though. What is currently being done is OK for demonstrating the use of =
a linked list, but what I have mentioned is more applicable for an =
implementation you are more likely to use in a real world application.

I don't use references much myself so I don't know much about thier =
syntax. Something I did read in Stroustrup was that you should avoid =
modifying values passed as arguments and instead use return values, =
because the user may not be aware that you have modified a value they =
passed.

In the end the choice is yours, so use what you want. It may be helpful =
to be aware of the alternatives. My explanation might not be very good =
as I'm having trouble trying to explain what I feel is right. I tend to =
rely on intuition a bit when deciding on how to go about a piece of =
code. Ask your teacher and see what he/she thinks about it?

In the end this is all over the top for what is needed so just ignore =
me. ;)

Jason.

  Hey everyone,

Re: [Dev-C++] my delete function in my linked list

[Jason H. <jas...@bt...>]

I'm not entirely sure what you believe is supposed to happen in it as is,
but you aren't keeping track of the node before the one with your info in
it. You need that so you can link around the one you are removing, as it is
a one-way linked list. Also, and I cannot stress this enough, you *MUST*
delete the pointer to the node you have, you don't have to do it in the
function, but as you don't return the node you remove you are losing it's
pointer. Try somethink like:

node delete_from(node *&list, int info)
{

   node *back, *current;

   current = list;
   back = NULL;
   while(current->next != NULL)
   {
      if(current->data == info)
      {
          // found node
          if(back) back->next = current->next;
          else list = list->next; // change start pointer
         return current; // return old node
      }
      else
      {
         // skip to next, but keep a copy of the old node
         back = current;
         current = current->next;
      }
   }
}

I'm a bit confused by your use of *&list in the arguments. I assume you you
want a reference to the list pointer so you can modify it, but I would have
thought that the correct notation would be &*list, or maybe &(*list)? I

PS: I've not tested the function, I'll leave that to you, but I think it
should work.

Re: [Dev-C++] linked lists

[Jason H. <jas...@bt...>]

Also in the  Create() function you create a node and put it the list pointer
you create, then you overwrite that pointer with NULL, which is a memory
leak as you don't deallocate the node you created. Also the function doesn't
return anything.

RE: [Dev-C++] linked lists

[Williams, T. W. <TIM...@sa...>]

In your main(), when you declare your first pointer to a node you need to
set that equal to NULL or 0.  The problem you were having is when you add
you were taking whatever address that was in list and just plunking it right
in ->next which isn't so bad if it's a good address but the way it was
written, when you were displaying it, it looped fine, but never got to NULL
and instead just trotted off into memory.
node *list = NULL;
instead of...
node *list;

Some time ago you asked this but I couldn't see if you got an answer =
already

PlaySound is a little tricky I had the same problem once

include <mmsystem.h>

and tell your compiler/linker to use libwinmm.a from DevC++
Lib-Directory ( ...\DevC++\Lib\libwinmm.a )

The linkeroption    -lwinmm    should do it

Good luck :-)

[Dev-C++] Efficiency

Can any one please show me how to increase the efficiency of this
recursive program?

THe program is supposed to output the fibonacci sequence up to a given

I need it to output in the middle of the recursive function, but
a lot of garbage gets acumulated.

Any help would be appreciated.

Thanks

I've never really used Visual C++, but I've found that most editors function
as I describe, including jEdit, KDevelop, and Emacs among others.  It just
doesn't seem very intuitive for the page to be filled with whitespace when
you've never hit the space bar or tab key.

[Dev-C++] Re:=?iso-8859-1?Q?=5BDev=2DC=2B=2B=5D=BFC=F3mo=20escribir=E9?= esto?

[carlos D. M. <cg...@wo...>]

Well, when i said unicode i wanted say ASCII and UNICODE both. And now I
achieved with ASCII to print them in a console program.... with a little
problem: with cout.put(number), after the character appears the number,
and with putchar(number) 0xfffffff after the character. Well, now I need
find if there are another equivalent funcion I can use for do it.
But I hope it is a problem for console programs, thank you.
I must change to learn windows programs.

I achieved it!!!!!!!!
With this strange thing (and complex, I still need pass to windows and
forget the consoles):
cout << static_cast<char>(static_cast<int>(static_cast<char>(160))) <<
endl;
Where 160 is the ASCII number for á.

[Dev-C++] Editor question

[Williams, T. W. <TIM...@sa...>]

I'm new to dev-c++.  is there a way to make the editor recognize line breaks
and white space differently.  actually, i'm not sure if that's the right
question, so i'll describe it.  right now i can click my mouse anywhere in
the editor pane and the cursor will go there but i'm used to (and would
prefer) to have the cursor go to the last available space.  in other words
properly follow the white space/ control characters.  it seems like it just
inserts false whitespace in the entire editor.  thanks,
--tim

I think this problem will go away if you don't write to the console,
but to a window. Probably the console uses another codepage (for ASCII
characters > 127) as dev-c++ (or any other windows editor, it seems).
I don't know how you can use these characers in a console, but probably
you will have to translate them to some old DOS codepage. Maybe you
can find info at microsoft. (http://msdn.microsoft.com)

I never used unicode myself, but I'm almost sure that .c/.cpp source
files are always ASCII, and not unicode - so writing unicode directly
inside the source code can't work. You have to write your unicode
strings with an editor supporting unicode (i'm not sure if it could
be integrated into dev-c++), and then you can display them in your
program, e.g. by using the Win32 API.

You should put #include <windows.h> as the first line of your .rc file,
else you can't use defined values like WS_POPUP..

[Dev-C++] =?iso-8859-1?Q?=5BDev=2DC=2B=2B=5D=BFC=F3mo=20podr=E9?= escribir esto?

[carlos D. M. <cg...@wo...>]

I have a problem with this compiler: When I try to write in the output a
character with accent or an ñ or ¿ or ¡, the (at this moment console)
program writes other character, a phi for í, beta for á, more-or-less
for ñ...
I found a page in www.cplusplus.org with the unicode for characters, and
I tried them with the cout.put() function, and it didn't work. I found
the official page of unicode http://unicode.org, and neither, now  it
writes something like 0xffffffffffffffff. And I haven't find anymore
about it. What can I do?  I CANNOT FORGIVE ME (and nobody) WRITE A BAD
LANGUAGE IF IT IS MINE COUNTRY LANGUAGE. IF I AM SPANISH I MUST SPEAK
AND WRITE PERFECT SPANISH. (i forgive to those who are not spanish or
spanish speaker countries, of course)

In regard to the Chris Hague message about .rc files, I have the same
problem, and I sorry because I don't know solve it, I say for know you
that that problem is not only for one person. I have the same with the
bitmap item. And with the font item it doesn't load the fonts.

So in Dev-C++ 5, it would be nice to make a compiler with support for
international characters in an easy way, avoiding the need of
questioning how to do it (support for unicode). (Or make it work fine).
And solve those problems. That can seem *not-to-this-list-questions* but
that *can-discover-some-fails-of-this-program*.
*or-foolishness-of-who-sends-it*

Re: [Dev-C++] C vs C++

[Jason H. <jas...@bt...>]

The reason you get that problem is because you now have to cast a void
pointer into the type you are using, and the old C style dynamic allocation
functions will always return a void pointer as they have no way of
determining the type of the value returned. i.e.

char *currentObjName = static_cast<char*>(calloc(100, sizeof(char)));

or if you are using C only you can use the old style cast: (char*)

for C++... yes you can use strings, but you can also use the new and delete
(or delete[]) operators. Strings are better for simplicity of use.

Jason.
