Re: [Dev-C++] windows programs and c programming

[<jos...@ya...>]

There are 2 main options to create projects:

- Console application
- Windows application

Depending on your needs you select one or the other. If you don't know
about windows programming and what you want to do is normal C/C++ stuff
then you have to select console application within project dialog.

In the same dialog where you choose "Console application" you can
select for C or C++.

This option is not available with the current version. Colin was

Re: [Dev-C++] Super Simple Bloodshed Question...

[<jos...@ya...>]

When you want to add a file to a project you should go to "Project ->
Add to project" and then select the file(s) you want to add. To remove
file(s) use the menu option "Project -> Remove from project".

You need _findfirst() and _findnext() functions those included by io.h
library. A simple code example given here:

#include <io.h>
#include <iostream.h>
#include <stdlib.h>

int main()
{
      _finddata_t myfile;
      int myhandle;
      
      if ((myhandle = _findfirst("*.*", &myfile)) >= 0) {
        do {
          cout << myfile.name << endl;
        } while (_findnext(myhandle, &myfile) >= 0);
        _findclose(myhandle);
      }
      else {
        cout << "File not found" << endl;
      }
      system("pause");
      return 0;
}

    Uh, if the there's-a-link-at-the-bottom-of-each-posting clue wasn't helpful enough... then
"several other poster" can "unsubscrobe" by following these instructions:

(1) Click link at bottom of this (or any other posting), in the automatically-generated
signature section.

(2)  Scroll to bottom.

(3)  Enter your email address (the one where your Dev-C++ postings are being sent).

(4)  Click "Edit Options".

(5)  Enter your password.

(6)  Click "Unsubscribe".

(7)  Wave "bye-bye"!!!

(Appendix A)  If you do not know what your "password" is, click the "Email My Password To Me"
button beneath the Unsubscribe section.  A shiny, brand-new, fresh-out-of-the-oven password
should arrive on your doorstep within the hour.

[Dev-C++] Info for unsubscribing from the list

[Ioannis V. <no...@ya...>]

Go at http://lists.sourceforge.net/lists/listinfo/dev-cpp-users

At the very bottom of the page it has a section saying:

To change your subscription (set options like digest and delivery modes,
get a reminder of your password, or unsubscribe from Dev-cpp-users),
enter your subscription email address:

There you enter your email address, press the edit options button and
you are presented with a page with the ability to unsubscribe.

Re: [Dev-C++] What lib should i be using instead?

[jansb000 <jan...@wx...>]

ITOA is a standard function. It resides in libc. Here is the description...

itoa
====

Syntax
------

     #include <stdlib.h>

     char * itoa(int value, char *string, int radix)

Description
-----------

This function converts its argument VALUE into a null-terminated
character string using RADIX as the base of the number system.  The
resulting string with a length of upto 33 bytes (including the optional
sign and the terminating `NULL' is put into the buffer whose address is
given by STRING.  For radixes other than 10, VALUE is treated as an
unsigned int (i.e., the sign bit is not interpreted as such).  The
argument RADIX should specify the base, between 2 and 36, in which the
string reprsentation of VALUE is requested.

Return Value
------------

A pointer to STRING.

Portability
-----------

not ANSI, not POSIX

Example
-------

     char binary_str[33];

     (void)itoa(num, binary_str, 2);

[Dev-C++] How do you compile a single file at a time?

[Paul P. <pa...@cc...>]

I have a project with about 50 files in it and I 
need to be able to compile just a single file at 
a time, but Bloodshed C++ doesn't seem to let me 
do this. There is only the 'compile' menu item and 
it compiles all files every time. This is very slow.

So how do you compile a single file at a time???

Hi Brian !
I'm not sure if the function "itoa" is ANSI C++; just in case it is not I 
included a "small" version of it.

This code might do what you expect:

test.cpp
---
// main is just to let me test the code

#include <fstream.h>
#include <string>
#include <algorithm>

string
itoa(int n);

//////////////////////////////////////////////////////////////////////

int
main()
{
    int number = 15;
    string filename = "help";
    ofstream data;

    filename += itoa(number); // append the integer
    data.open(filename.c_str()); // see STL help file for c_str()

    data << "this string goes in the file: \"" << filename << "\"\n";

    return 0;
}

//////////////////////////////////////////////////////////////////////

// convert a non-negative integer to a string

string
itoa(int n)
{
    string s; // the number as a string

    if (n >= 0) // convert
    {
       do
          s += '0' + n % 10; // add in reverse order
       while (n /= 10);

       reverse(s.begin(), s.end()); // set in the right order

    return s;

[Dev-C++] Super Simple Bloodshed Question...

[Paul P. <pa...@cc...>]

Super Simple Question:
   How do I open more than one file in the program?

If I use the "Open Project or File" menu option to open 
a .h or .cpp file, it insists on quitting the entire project!
There is no way to drag and drop a file onto the program 
to open it. If I put a .h file into the project tree, the 
program goes crash crazy.

Thus, I can find no way to actually open a second file.

[Dev-C++] RE: lib

[Brian P. <BP...@go...>]

I must have a different lib because itoa(int) is not defined but itoa(int, char*, int) is?

*
*
*
v

I am not all to familiar with the string class that you are using, but 
"filename += number" may not do what you think. 

try this instead: 

// 
string filename = "help"; 
int number = 0; 
filename += itoa(number); // convert int to char before appending it to 
string. 
cout << "{" << filename << "}" << endl; 
// 

You will now see that a space is added between filename and number. This 
character position is to represent a minus sign if number is negative. Your 
string class will probably have a function to get rid of this character.

hi all,

(just started with DEV Cpp)

I am about to start with win32 programming and need at first a 
program to access the serial port (COM1/2) to monitor data and

Does anybody know some sources for example code for this ?

I also want to store the data into a access database via DAO.

(i did not do this also so far).

I assume there should be many applications, which did this 
allready in a similar way.

Anybody has an idea where to go and get sam samples for thes 
prposes ?

Thanks very much in prgrogress.

[Dev-C++] Linker error

[Graeme F. <gr...@dr...>]

When compiling any project I get the following linker error:

gcc: \cc490425.i: No such file or directory
C:\Dev-c~1\bin\windres: gcc exited with status 1: can't execute 'gcc': No
error.

I have come across the following error on a couple of machines. Removing
Dev-C++ and reinstalling doesn't help. One machine I needed to reformat the
hard disk, for completely different reasons, and that sorted it out! But I
feel that is rather too drastic to fix the laptop!

The only solution I have come across is to remove the resource file from the
project.

Does anyone have any suggestions?

Graeme.

[Dev-C++] [Dev-C++]Opengl Book

[Vassili <v.v...@bt...>]

Came across the 1994 version of "Opengl Programming Guide", I couldn't =
get to the auxiliary file that goes with it, but on second viewing it =
could easily be replaced by glut.=20
