Darel & SipderMan,

I took a look at wxdesigner and it looks like a nice dialog editor,
however
I don't think I wanna do WX-Windows and learn C too. Also at this point
I'm
not concerned about cross-platform functionality.

I downloaded the Windows Dialog Editor also. I be using this until
somethig
better (and ofcourse free) comes along. Oh BTW, there seems to be
at-least
one control missing - the Tab control. Maybe I don't have the latest
version(3.10.164)?

Thanks and Regards,
Sam

Passing a file name to a console program as a parameter requires full
path to work by clicking "Run" under IDE. Without full path the
executable is not able to locate and open the file. Normally, the
executable should find the file in the working directory. This means
that the environment option to "execute in directory of executable" is
not working even if checked. In fact, the executable runs in
c:\dev-c++\bin\ directory, I suspect.

To observe the behavior 
1) run devcpp.exe from program menu.
2) compile this program:

#include<stdio.h>

main(int argc, char** argv)
{ 
  FILE *f;

  if ( argc > 1 )
  {   
      f=fopen(argv[1],"rt");
      if( f==NULL )
        printf("File %s has not been found!!!",argv[1]);
      else
        printf("File %s has been found and opened. ;\)",argv[1]);
  }
  else
      printf("No file name has been passed!");
  printf("\n press any key...");
  getchar();
}

3) try to pass an existing file name to this problem and run it under
dev-c++.


Running devcpp.exe in the directory of executable solves the problem.
Unfortunately, recompiling resets the working directory from the
directory of executable.

This small program will read your file with all char included.
Once you get further into "c" you will learn about structures & objects,
which are much better for file applications.
lstar36
#include <string.h>
#include <stdio.h>
#include <stdlib.h>

void    main(void)
{
    FILE    *stream;
    char     string[132];// be sure to make this array as big as your
longest string
    char    *eof;
    int     size;

    size = sizeof(string)+1;
    eof = malloc(size); // allocate memory for string
    stream = fopen("Myfile.txt","r");
    do
    {
        // returns a NULL on end of file
        eof = fgets(string, size, stream); //reads a max of 132 char or
untill new line.
        printf("%s", string); //
    }while(eof != NULL);
}

hi,

i've downloaded dev-c++ 4 and i'm unable to set the editor color attributes
(i'd like comments normal font, not italic)

TIA.

Miquel Matas(Barcelona(Spain)).

Can I format input from a file inside of the file or do I have to do
this through code? I am trying to import characters into my program as
they are in the file. when I use fscanf it ignores the spaces. I was
wondering if there is a way to essentially cut and paste from a file to
my program including the spaces and returns. To explain, I am trying to
import ascii art into the introduction portion of my program, so the
input file needs to be formatted exactly as it is spaces and all. I am
taking a class in C, very new at this, so I am playing with it.....
thanks in advance for the reply.
                                                   Blalock

This code is just the bare bones and should do more error checking etc.

					In 'C' try:

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

int main(int argc, char *argv[])
{
  FILE* outfile;
  char fname[] = "myfile.txt";
  if((outfile = fopen(fname, "w")) == NULL)
  {
   perror(fname);
   exit(1);
  }

  fprintf(outfile, "This text should now be in your file.\n");

  fclose(outfile);

  return 0;
}

					In C++ try:

#include <stdio.h>
#include <fstream>

using namespace std;

int main(int argc, char *argv[])
{
  fstream mystream;
  char fname[] = "myfile.txt";

  mystream.open(fname, ios::out);

  mystream << "This text should now be in your file." << endl;

  mystream.close();

  return 0;
}

Regards,

James.

Microsoft's Platform SDK contains a dialog editor. It saves the dialogs as
.res files.

I think (IIRC) that it is referencing the wxWindows dialog editor.  I
haven't used it much, so can't comment on that.  However, take a look at
wxWindows.org and check the links there.

    You can find the dialog editor from Windows Platform SDK at my site: =
http://spiderman.datablocks.net/files/tools/ If your going to be doing =
Win32 development I highly suggest you go to http://msdn.microsoft.com =
and download Platform SDK (get the documentation). A word of warning the =
SDK is a big download, but well worth it.

For parsing regular expressions check out the boost library. Info can be 
found the their website.

http://www.boost.org/

specifically

http://www.boost.org/libs/regex/index.htm

As for accessing web pages, (and by that I assume you mean remotely 
connecting to a web server and requesting a page from it which you then read 
into your program) you'll have to look into some networking functions. AFAIR 
Windows can use a similiar API to BSD style sockets. It should be relatively 
easy (assuming you know that API. If not I can try to explain it a bit or 
refer you to some web tutorials) to establish a TCP/IP connection to a 
remote web server on port 80, send it the get request, and read the data the 
server spits back.

Hopefully that should help some,

Chad Simmons

Hello,
 
There's a package called WxWindows that has HTML support. It's packaged
for Dev-C++, you can find it by following the links from bloodshed.net.
I haven't used it but I think I recall it's a cross-platform system. I'm
not sure if there's a linux support.

Hi, 
Check http://members.fortunecity.com/synchu/ for 
precompiled wxWindows 2.2.1 libs. Dont forget to read 
the page 'till the very end of it (where actually is 
the readme file, with a little bit configuration stuff 
in it:) ).

Using system("pause") to keep the DOS console window open is actually =
covered in the DEVC FAQ - it was the first question that I wanted to ask =
too....:)

This seems to be a common question....I too had the same problem....I've
been using the following command before the return statement.

system("pause");

Basicaly the system call works with  DOS commands like pause and cls.  I
haven't tried others, but these two work to hold the screen and clear the
screen.

Hi-
I have programmed for many years in perl, but I haven't taken more than a
glance at C++ until now, so please excuse my ignorance.
I am looking for a way to access web pages from my program. They are not web
pages per se, but text files accessed over the web. I need to be able to
parse these for strings. Regular expressions might be the way to do this. I
know that there is a library called libWWW, but I have never used it except
for it's perl incarnation, LWP. I would like the solution to be
cross-platform between windows and linux, as I am developing a wxWindows
application. I have attached some sample output to the end of this email.

I'd like to turn this into some inteligent data structure. The data fields
are
     label
     sm_address
     domain
     folder_id
. I would also like to put this into a treectrl in wxWindows, but I think I
can figure that out.

well, i'm in the same situation :) i really want to port Dev-C++ to Linux
because i really think Linux is better than Windows (or i won't be using it
everyday ;)
However, i'm waiting for the Kylix tool (Delphi for Linux) that Dev-C++ can be
port to this OS. The development of Dev-C++ for Linux will probably start
between December 2000 en February 2001.

    As defined in Dev-Cpp's conio.h file, getch() is a macro for getchar(),
not the other way around.  Both getchar() and gets() have actual prototypes
in stdio.h.  Scanf() does indeed echo to the screen.  Finally,
getch()/getche() were the functions that were giving me problems to begin
with

    Er...  I was hoping to avoid doing my own single-line editor...  I'd
like the program to have the ability to backspace/edit and the like, not
just suck in characters.

    Thanks for your suggestions tho

    Well, that works, but getchar() is line-buffered.  Any ideas how I could
do it without hitting <return> after my selection?  Not a very big point,
but it makes things a tad more user-friendly.

    Yikes, do I need to get better docs for the C standard libraries.

    Thanks for all your help,

Problem1
The getchar() and getc() functions are both macro's and leave a char (i
think line feed char = 10) in the buffer. getch() and getche() are both DOS
only functions but do not leave a char in the buffer. Unless you are worried
about portability I would use one of them.Otherwise use the scanf() function
to read in a line of code .
scanf("%d", &choice); It will not echo so if you want to see your input you
must writ the char back to the stdio.

Problem2
For reading from the stdin the best way is to use a loop:
char    ch;
char    string[82];
int        i=0;
do
{
    ch =getch();
    string[i++] = ch;
}while(ch != '\n" || i <= 80)

hope this helps.

Hi

I'm new to this list. I'm trying to learn WxWindows using Dev C++ 4. I
downloaded the libs for WxWindows and the templates from the extra packages
page (this is for Wx 2.2.0). I also downloaded the latest version of
WxWindows (2.2.1) from the WxWindows site. However, I am unable to run the
sample programs supplied with it using Dev C++. Has anybody else tried this
successfully ? If yes, can you advise regarding what extra steps are
required ?

Thanks in advance.
Biswa.
