Well my advice to you would be to start with the simplest possible code, and
then work up to the complicated version. Also, when working with classes, it
helps to draw some kind of simple paper diagram. At my desk, I have posted
the diagrams of the <ios> hierarchy and the <stdexcept> hierarchy for
example.

Here would be some really trivial multi-class code. Note how you can catch a
runtime_error as an exception because runtime_error is based on exception.
If you look at the stdexcept system header or the docs for this header, you
can see how this works in more detail.

Also, google "C++ polymorphism" as well.

HTH!
Matt


#include <stdexcept>
#include <iostream>

using namespace std;

int main(int argc, char* argv)
{
    try
    {
        throw runtime_error("foo");
    }
    
    catch (const exception& e)
    {
        cout << e.what();
        return 1;
    }
    
    return 0;
}

Subject: [Dev-C++] Base classes....


Hello all,
    I am making a plugin manager that loads dll's and stores pointers to the
imported classes in vector so users can request the classes when ever during
the program. However the problem lies in the fact that vectors or arrays can
only store one type of object in other words one type of class pointer which
will not work. I know that a base class pointer is compatible with a derived
class. I was thinking about creating a base class where all plugin classes
are derived from. I know this is possible because Crystal Space 3d uses the
same technique. I'm just not sure how. I've included the file where the base
class in Crystal Space is  declared. Maybe someone can make some sense of it
all.  I tried to reduce the file size, so if anyone need the rest just say
so. Thanks.

That annoying line is there actually to remind you how wide is the 80 
column terminal screen. If you wish your code to be readable on one such 
thing, that line comes really handy.

Happy coding,
next_ghost

LOL, Doh!  I can't believe i missed that!!!!!!!
Thanks though...

Cheers,
Scott.

editor options, uncheck right margin visible

Is there a way to remove the (what seems to be a page break) line=20
green or grey in colour that seems to do nothing except visually impair =
my code...

I cannot find any reference to it's name or use, in the Editor Options =
etc...

It's like a margin line?


Anyone?

Cheers,
Scott.

The #ifndef HEADER_H... construct only protects from inclusion of a
specific header file once from the SAME C-filer. Not from inclusion by
multiple C files.

In the header file, you should normally write

extern int p;

and then in one of the C files write

int p;

Or you can modify the files to look like:

--- header.h ---
#ifndef HEADER_H
#define HEADER_H

#if defined IMPLEMENTATION
#define EXTERN
#else
#define EXTERN extern
#endif

EXTERN int p;

#endif
---------

--- main.c ---
#define IMPLEMENTATION
#include "header.h"

int main() {
   ...
}
----------

--- other.c ---
#include "header.h"
...
------------

Hi,
Please help me with the following code. We have three files: a header fil=
e =20
and two
implementation files.

// Source of "header.h"
#ifndef HEADER_H
#define HEADER_H

int p;

#endif
--------------------------------
// Source of "main.cpp"
#include <cstdio>
#include "header.h"

int main()
{
     printf("%i\n",p);
     return 0;
}
--------------------------------
// Soruce of "func.cpp"
#include "header.h"
int func()
{
     return p;
}

The compiler generates the error " multiple definition of 'p' ".
What is wrong with the code?
When the header file is included for the first time, the macro "HEADER_H"=
 =20
is defined
but when the header file is included in the second implementation file,
"HEADER_H" can not be recognized in the second file and "p" is defined =20
once more!!
It seems macros have file scope.

Thanks,

     Hello developers,
I'm going to release new version of devpaks.org web interface
and I'm looking for betatesters. The beta version is available
at http://beta.devpaks.org/ . It would be nice if somebody
can play with it for a while, trying to add some devpaks etc.
Don't hesitate to do whatever you can image with it, all data
will be deleted before releasing it.

YES!!
It did the trick, but the DOS prompt pops up when I run the program, is
there a fix for this?

Thanks Daney and Per, you guys are the best!!

You could try reading until the end. The item [4] says exactly what Per 
W said.

I think that this problem is related to the make version. Seems that 
yours isn't expanding the `` command.
What's the output for "make --version"?
Mine (MSYS' make.exe 3.79.1 and mingw32-make.exe 3.80) work fine. If I 
try "make --win32" then it gives the same error.

When specifying `something` on the commandline, that means that
`something` is an application, and that the output of that application
should be used as command-line parameter.

This is a quite common way to configure programs on Unix machines, but
Windows doesn't support this feature.

Manually run whatever command is specified within `` and take the printed
output and insert instead (while removing the ``).

Thank you Daniel for your prompt response.
I did as you suggested and followed the instruction in the
'.../gtk_win32_tutorial', it was very informative. However, when trying t=
o
compile the program suggested by the above webpage I get the following
error:

make.exe -f "C:\tmp\Makefile.win" all

 -mms-bitfields `pkg-config gtk+-2.0 --cflags`

cc1plus.exe: error: unrecognized command line option "-fcflags`"

g++.exe: `pkg-config: No such file or directory
g++.exe: gtk+-2.0: No such file or directory

make.exe: *** [main.o] Error 1

What could be wrong?

Again thanks so much for the help.

Howdy folks!
I have installed the GTK+ runtime as well as the GTK+ development
libraries on my MSW-XP; I would like to use Code::Block or Dev-C++ as the
IDE, but I have found that none of these IDEs have default settings for
GTK+. I have tried to get the right settings on my own, but to now avail.
So, I was wondering if someone here could give me a hand on this one.

TIA

what did you say?

Anyone know if there is a function call in c++ where if the user enters an
'A' or an 'a' it would be displayed as an 'A'. I know I can use an OR (  ||
).  Which I can use and works perfectly fine, but I was just curious is
there was a function call in c++ that if any letter was entered it would be
taken as a capital letter.  I need to do this to about 15 letters. Any
suggestions? Or should I just stick to the OR method. Thanks.

You think about:

#include <ctype.h>

int toupper(int c);
int tolower(int c);

There are also a couple of similar functions directly for the Win32 API,
for Unicode, wide characters, ...

Note that setlocale() affects treatment.
