Hello,

Where find the help file win32api.hlp and devcpp.hlp in french language 
please or how decompile for translate?

Re: [Dev-C++] Please spot out the cause of this bug

[Per W. <pw...@ia...>]

First of all - i don't like a construct:

  if (strcat(x,y()) == NULL) ...

since that implies that x is NULL - strcat doesn't perform any
reallocations, it just returns the address of it's first parameter! You
should have checked up on x long before, i.e. when you allocated x. Unless
you are using a nice and current C++ compiler, in which case the new
operator don't return a NULL.

Second: Why bother with a list/queue/vector/... of lines. All you need is
the current and previous lines in memory. Why? If you previous line ends
with a // comment and your current line starts with white space followed
by //, that is enough to activate conversion mode. Emit previous line
but with the comment using "/*".

Then just pricess lines until you find a line that doesn't start with
white space followed by "//". Emit previous line but with an ending "*/".

This state-machine concept allows you to handle a 10-million-line comment
without requiring any extra memory. All you need is memory enough for two
arbitrary long lines.

[Dev-C++] console window and gui

[Guillermo G. <ggu...@ma...>]

Hello,
I was wondering, how do I go about getting a command prompt to appear in =
the background with my GUI application.
If I compile and the flu_combo_box.cpp example I see the GUI app with a =
console to display the output of the printf() commands.
I have tried removing the -DWIN32 compiler parameter, setting it as a =
win32 console app (which wouldn't let it compile btw).

what can I do, is there some sort of debug option for dev-cpp-4990 with =
GCC-3.3.3.
I am on a win2k machine.

Try Jimmy Venema's ClassBuilder! It is pretty usable at 2.4. The development 
has been stalled for several months but the author says it is a temporary 
situation.

I am pretty shure that the Dev-C++ class anager includes that feature. I can't

[Dev-C++] Search for a kind of "Class Builder"

Hi all,

First sorry for my bad English, I'm french.

I discovered Dev-C++ and I wonder if it exists a kind of "class builder" 
which can help me to create HPP/CPP files quickly.

If not, can I extend the software (by a sort of "plugin", I mean) to include 
a such tool created by myself (I'm used to develop with Delphi) ? How ?

Thank you !

[Dev-C++] updates failing in 4.9.9.0

[Zachary U. <ne...@gm...>]

Hi,

I installed Dev-C++ 4.9.9.0 (full version) in Windows 98, SE and when
I use the WebUpdate Module it never installs the update.

For example:

I selected mirror "PlanetMirror.com"

next checked box for "Dev-C++ Update"

and click "Download Selected"

it downloads the file and the status changes to "disconncted"

then nothing happens!

i watched the download progress meter so it seemed to complete 

then the app just freezes, even if i click on "close" nothing happens

but if i do Ctrl-Alt-Del I see the process and it doesn't say "Not
responding" or
anything , and as soon as I cancel the Ctrl-Alt-Del a dialog box pops
up in Dev-C++ saying "The updates you selected have been downloaded.
They will now be installed"

so i click "OK" and nothing happens :(

if i close Dev-C++ and repeat the whole process i get same result

i recall using older version 1 year ago also in Windows 98 SE and
never had this problem.

help please :)

Joke aside. Given the large number of applications developed using gdb, I

Re: [Dev-C++] Wave generator program

[Per W. <pw...@ia...>]

Anything happening in and around the processor is so fast that the
processor itself can't process the signals and emit them. That is the
reason people buy _expensive_ logic analyzers if they want to look at
computer hardware signals.

The only kind of signals you can produce is sound-frequency signals, where
the processor (or DSP of the sound card) may produce wave forms and then
emit them on the analog or digital output of the sound card. The best
cards support output up to 192k samples/second.

They are garbage of uninitialized memory.
If you read the documentation for strncpy() you'll see that it copies 3 
characters when you call it.
None of your 3 characters are the '\0' terminator, because the '\0' it's 
beyond the 3 chars you are copying (it's the 5th char in "JACK", and 9th 
in "ROBINSON"). So you get a non-terminated string. When using strncpy() 
you have always to terminate it by hand.

strncpy does not append a NULL if there isn't a NULL in what it's 
copying.  So... FirstMix wasn't set to all nulls when it was 
initialized and when you copied the first three characters into it, 
there was no null to signal the end of the string.  You can't assume 
that an array of chars will be initialized to null.  Sometimes it 
will be and sometimes it won't.

You can fix that by either initializing the string to all nulls or by 
inserting the null after the strncpy.  For example, check out these 
modifications to your code:

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

#define SIZE_OF 15

int main()
{
char FirstName[SIZE_OF], SecondName[SIZE_OF], 
FirstMix[SIZE_OF],SecondMix[SIZE_OF];
  // used SIZE_OF instead of declaring each array size individualy

strcpy(FirstMix, "123456789");

printf("Please enter the name JACK\n");
scanf("%s", &FirstName);

printf("Now please enter the name ROBINSON\n");
scanf("%s", &SecondName);

strncpy(FirstMix,FirstName,3);
printf("FirstMix=%s\n", FirstMix);

strncat(FirstMix,SecondName,3);
printf("FirstMix=%s\n", FirstMix);

strcpy(FirstMix, "123456789");

strncpy(FirstMix, FirstName, 3);
FirstMix[3] = '\0';
printf("FirstMix=%s\n", FirstMix);

strncat(FirstMix,SecondName,3);
printf("FirstMix=%s\n", FirstMix);

system("pause");
return 0 ;
}


And here's the output:

Please enter the name JACK

FirstMix=JAC456789

FirstMix=JAC
FirstMix=JACROB

The trouble is having compiled the code I keep getting a strange output,
my code is

#include <stdio.h>
#include <string.h>

#define SIZE_OF 15

int main()

printf("Please enter the name JACK\n");
scanf("%s", &FirstName);

printf("Now please enter the name ROBINSON\n");
scanf("%s", &SecondName);

strncpy(FirstMix,FirstName,3);
printf("FirstMix=%s\n", FirstMix);

strncat(FirstMix,SecondName,3);
printf("FirstMix=%s\n", FirstMix);


return 0 ;
}


and my output is 


Please enter the name JACK
JACK
Now please enter the name ROBINSON
ROBINSON

has anybody an idea as to where the extra characters are coming from????
thanks in advance.

This is (for me) the most in C++ style. For better similar to IntToStr()
from Delphi it can (?) be written as:

#include <sstream>
std::string itos(int i)
{
  std::stringstream s;
  s << i;
  return s.str();
}

(Example found via google).
