dev-cpp-users Mailing List for Dev-C++ (Page 758)

Hi everyone,

Just a quick question that has been bugging me!

I if compile the program:

#include <iostream>

int main()
{
 cout << "Hello World!\n";
 return 0;
}

It works perfectly! But surely it should fail because I have used the =
new style header files that are placed in namespace std. Being as I have =
not added 'using namespace std;' to my program - why does it work?! I =
though you had to qualify each function with std::

Im sure there is a good reason for this - Im just interested!

Chris

Dear Friends
Does exist any italian version of DevC++?

Your program compiles and runs fine on my system. I am using borland c++ Ver
3.1. The change sugested below should not cause any change as the default is
to open in read mode.

Hi there everybody!

I was wondering... where can I get Turbo C++ 7.0 (or later)?

Thanks, 'n ceep coding! :-)

-------------
#define stone

I am trying to compile and run an example program from
	http://www.relisoft.com/win32/generic.html

I created a Project file I called Win_Gen in Dev-C++, removed the default 
"untitled.cpp" file it opens and added all the files from the generic.zip file.
Then I did a "Save All" and a compile and got the following error message:

Line 76   winmaker.cpp ANSI C++ forbids implicit conversion from 'void*' in
	argument passing

I got the same error message for Line 85.  These lines are both in
	void WinClass::SetResIcons (int resId)

Does anyone know the fix for this in Dev-C++ ?

Just a thought!

Have you defined in main.h

#define CM_HELP_ABOUT 1000 // whatever number. 1000 is an example.

?

Everything looks perfectly normal, but you get and error on line 14.
That is the only thing I can imagine.

Hope this helps.

Hi,

Just a quick question. If I call sin.sync_with_stdio(), will it =
guarantee that getch() will work with cin/cout without problems?

Chris.

Esteban,

Hi. If you remove 'ios::nocreate' from the line where you open infile, I
think you will find it works as planned, as follows:

    infile.open(filename);

Hope this helps!

Hello, I am new to C++.
I am following a tutorial in wich it appears the following code (wich makes
a copy of a file):

	#include <iostream.h>
	#include <fstream.h>
	#include <process.h>

	void main()
	{
	ifstream infile;
	ofstream outfile;
	char filename[20];

	   cout << "Enter the desired file to copy ----> ";
	   cin >> filename;
	   infile.open(filename, ios::nocreate);
	   if (!infile) {
     		cout << "Input file cannot be opened.\n";
	      exit(1);
	   }
	   outfile.open("copy");
	   if (!outfile) {
	      cout << "Output file cannot be opened.\n";
	      exit(1);
	   }
	   char one_char;
  	   while (infile.get(one_char)) {
      	outfile.put(one_char);
	      cout.put(one_char);
	   }
	   infile.close();
	   outfile.close();
	}

It should create a copy of the original file into the file "COPY". The
program compiles and runs properly but the file COPY is empty (it exists but
has 0 bytes), what is wrong?

thanks. Esteban

Hello everyone.

Ive written the following function which overloads the insertion =
operator for a class for restricting the input of a string to digits =
only:


class mystring
{
 char *str;

 // ....
public:
 friend istream& operator >> (istream &is, mystring &rhs);

 // ...
};

istream& operator >> (istream &is, mystring &rhs)
{
 char buf[256];
 char ch;
 short len =3D 0;

 do
 {
  ch =3D getch();

  if(isdigit(ch))
  {
   cout << ch;
   buf[len++] =3D ch;=20
  }
 } while(ch!=3D13); // while not 'return'. =20

 buf[len] =3D '\0'; // terminate string;
 rhs.str =3D new char[len];
 strcpy(rhs.str, buf);

 return is;
}

This compiles and runs fine on my compilers, but when I compile it and =
run it on my college compiler (MSVC++) getch and cin/cout dont get =
along!

My question is - being as getch() is non ansi and it also uses different =
buffers than cin/cout - is there a way of writing a simular function =
without using getch? getch is good because it doesn't display inputted =
characters and doesn't wait for a return keystroke, but I dont know how =
to achieve the same thing using cin/cout.

Any ideas?

Thanks in advance=20

No, since getch() is not part of ANSI C++. Also it is not even part of ANSI
C, so any program using getch() is not considered portable.

Hi everyone.

I wrote a function using dev c that overloads the insertion operator for a
class. I used the getch() function within this function and everything
worked fine.

However, when I took this code to college the next day and compiled it under
MS Vusual C++ it caused all sorts of problems. My lecturer said this was to
do with getch using different buffers that cin.

Is there a way to make sure that getch will work with cin on all compilers?

Thanks in advance.

Hi

Has someone ever compiled the FOX toolkit library using the dev-c++ =
environment ? The FOX web site said it could be done using the mingw32 =
compiler, but I don't know if it could be done using the IDE.

thanks

Hi everybody,

I also encountered problems searching for non-MFC API related sites. I
decided then to create personal pages including those sites so everyone
can have a look to them and learn.

line... I moved things around a bit and it seemed consistant).

  The project was a simple C WinMain project (I'm not sure if this =

than simple Windows interfaces is a little frustrating (I think I can =
handle the underlying C++, but there's only one way to tell! 8-)

Hello,

Here.  Let's try it this way (I hate my mail client by times... sorry =
about the double post guys).

How about something along these lines for variable spacing.

printf("%sSomething else.", sVar);

where sVar is a variable number of spaces.  You should be able to fill a =
string (character array in this case) via something in the <string.h> =
(or <cstring.h> if your compiler is predominantly C++) library.

strcat and strlen might be of use.
  I am trying to make it where I can put spaces into a line but at =
differing lengths each time.=20

Hello,
  I am trying to make it where I can put spaces into a line but at =

If you're using C (as you've said), you could try something along these =
lines...

#include <stdio.h>

No.

You can try  #define, #ifdef, #ifndef, e.t.c. in some way but if you want to
create spaces only you can try something like this:

int main()
{
int i=0, spaces=0;

/* spaces are defined somewhere in the code */

for (i=0; i<spaces; i++)
printf(" "); /* It inserts spaces in a line */

...

return 0;

windres).  It always points to the line following the initial 100 =
DIALOG... line (I'm assuming here that the error number refers to =
line... I moved things around a bit and it seemed consistant).

The project was a simple C WinMain project (I'm not sure if this factors =
in or not).  I only know that if I add any other type of resource that I =
get no errors in the compiling of the resource script.  I've been trying =
to find documentation on windres (without any good hits, aside from =
command line options...), and I can't get to bloodshed.net (maybe this =
is a known issue?).

Any help here would be appreciated.  I was developing a little class =
building utility in RapidQ (a nifty little BASIC style language - now in =
limbo as it's author was picked up by a software company [Ah!  So dreams =
do come true! 8-)]) but have found that I would now rather just "bite =
the bullet" and use C++.  However, my inability to create anything more =
than simple Windows interfaces is a little frustrating (I think I can =
handle the underlying C++, but there's only one way to tell! 8-)

Thanks again.

More, if I remember correctly (thousands, only about 3000 common characters
though).

It wasn't my intention, by any stretch of the imagination, to be
ethno-centric (neutrally or negatively).  My apologies, whether I have given
offense or not.  Traditionally, I've heard the "It's Greek to me...";
however, these days, just about any non-English language is used (though
some less often than others).  From this point onward, I shall put a little
more thought into what I'm thinking and typing!

Here I was thinking that "long in the tooth" had been misunderstood.  Funny
how the international nature of the Internet points out glaring oddities in
one's behaviour/thoughts.  (For what it matters... I try to avoid smart-ass
American comments...  I use smart-ass Canadian comments 8-).

Anyhow, on a different note.  Many thanks for the wealth of resource
material that everybody took the time to point out.  It'll no doubt take
some time to digest (so I'd best get to it! 8-).

P.S.
A further note. I'm current with Dev-C++ 4.0 (I like the extended Tools
menu... You CAN run your favourite MIDI file from it! 8-)  Is there a
"plug-in" style API for Tools? (I admit, I'm remiss in downloading the
source for the IDE, and my Delphi is... nearly non-existent, so it might not
be my choice for developing something like that.)
