I think it would even help if most people would quote right like

Re: [Dev-C++] Design decision in C++

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

The only real advantage of a static object is that you don't allocate it
which might be an advantage in a small embedded environment - you might
write the application without support for dynamic memory.

If the class on the other hand has only static members, you don't have to
send the "this" pointer to the member functions. A very minor improvement
that is mostly eaten up for a number of compilers by loss of a couple of
compiler optimizations specially added for C++ object accesses. If the
class is using static methods it has to use static member variables too,
which is a bit bothersome, and you don't get to use a constructor.

Some notable advantages of Singleton objects are:
1) Constructor is run after main, so it might be easier to debug.
2) Programmer control when constructor is run, which is advantageous if
multiple classes relates to each other, and you want to control order of
construction.
3) If you later realizes that you need more than one object of a class, it
tends to be easier to modify the program if the class was originally using
the Singleton pattern. A solution with static methods requires heavy
rewrites.

This is thread is especially interesting to me, as I'm working on a 
project that uses Singleton for a number of its classes, and I'm not 
sure it is warranted.  No one has addressed Michael's original question: 
what are the tradeoffs between using Singleton and just making the class 
(or all of its members) static?  I'd like to know about others' 
experiences with Singleton, in case it's advisable to move from 
Singleton-based classes to static classes in my project.

Re: [Dev-C++] Design decision in C++

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

I would instanciate a single object using the singleton design pattern.

Make the only constructor private, and add a public static method to
create and retrieve this single instance:

class MyClass {
    private:
        static My>Class *myself;
        MyClass(); // Note constructor private!

    public:
        static MyClass* getInstance() {
            if (!myself) myself =3D new MyClass;
            return myself;
        }
};

__argv[0] has the entire path to your application binary.

For example: "C:\Programs\MyProg.exe"

All you need to do, is to strip off "MyProg.exe" (your app name).
I suspect you wish to save config files, eh? :)
(Well, at least that was why I needed to search for a solution a few=20
years ago, and that's what I found).

One last note: I used __argv because if you have a WinMain in you=20
program, then you don't have argv simply. But __argv is always present=20
(as well as __argc), it is global, and has the same contents as argv and=20
argc would (at least in MinGW).

Thank you for streamlining the code! Your version is much more elegant than
my "beginner" one.
I will try now to use the following function, in order to assure that the
size with which the buffer char array is defined, is enough to contain a
path...

	size = pathconf(".", _PC_PATH_MAX);



Thanks,

Josep

Wrong use of getcwd - it doesn't allocate any memory. You have to supply
the memory it should use.

When you create a shortcut, you can specify the working directory, i.e.
where the program should be started.

getcwd() will - on startup of the program - always return this directory.
However, using getcwd() you may use multiple shortcuts that specifies
different working directories. getcwd() will then return different paths.
However, if a user has specified two different working directories, I
thinkt that is an expected behaviour.

AW: [Dev-C++] embedded mysql

[Josep S. <sub...@ar...>]

Hi Oliver,

>>i would like to know how to run this embedded mysql together with dev-c=
++.

I've put a .zip file on my website:

  http://www.subirana.de/embedded.zip

 with the Dev-C++ Project file + cpp files + libraries and includes + dll
...all you need to compile and run/test embedded mysql. This Dev-C++ proj=
ect
is an adaptation of the Visual-c++ project that comes with the mysql
distribution. The libmysqld.a library works without problems with Dev-C++
(The libmysql.lib library that comes with the mysql distribution doesn't,=
 so
I had to find a way to get a working one). You just have to compile the
project and run it: you should get some information about the "paro"
database, included by me for testing purposes in the "data" folder in thi=
s
.zip file,  followed by a list of all the databases that embedded mysql
finds in the data folder.

It it doesn't work for you please don't hessitate to contact me again.

The normal mysql is rather though for multi-user client-server applicatio=
ns:
it runs as a separate service and has be started before you can use your =
c++
application that uses it. With EMBEDDED mysql in your dev-c++ programmes,
you don't have to start mysql before you can run your programm... mysql
doesn't even have to be installed on the machine you'll run your c++
application onto (it's already contained in your c++ programm). There are=
 2
types of License for embedded mysql: the usual open source one (I think i=
t's
called GLP) and a commercial one if you don't want to realease your code
with your programms (please see: www.mysql.org)

An alternative to embedded mysql is: sqlite --> also an embedded database=
,
but mysql is the preferred database worldwide and can do a lot more thing=
s
than sqlite!

Hi Paul,

Thanks alot for your hint! I'm a bit new to API and I don't know with c++ if
I have to declare this function (GetModuleFileName()) in a header or what I
do have to do in order to being able to use this function you describe.
Could you help me on that too? (If I need a function declaration in my
header, could you please post it with the right variable types or point me
to a website where i can find those API function declarations???)

Thanks again,

Josep

BTW,
I've tried with the following code, but I don't know if the *working
directory* is always, at the beginning, the same as the directory where the
.exe file lies!!!

  const long size = 1000L;
  char *buf;
  char *cwd;
  //size = pathconf(".", _PC_PATH_MAX);

  cwd = getcwd(buf, (size_t)size) ;

  char flag[size] = "--datadir=";
  char *subdir =  "\\data";
  char *foo = strcat (buf, subdir);
  strcat(flag, foo);

  int argn = 3;
  char *arg[] = {
    argv[0], "c++", flag
  };

  mysql_server_init(argn, arg, (char **)server_groups);

For the original poster: Don't know if it will help you, but in Win32 I get
the path to the running application like this:

char szBuf[512];
GetModuleFileName(NULL, szBuf, 512);

(if the call succeeded, szBuf now contains the full path to the current
module (executable))

To Per:
Thanks :D I forgot that lots of things are file (or pseudo-file) based in
Linux. But it appears that /proc/self/exe is a symlink to the current
binary... which brings me to a second problem: How do I get the target of a
symlink as a string or something :) Whenever I'm programming for Linux I
constantly run into problems, cause I have no clue where to get MSDN-like
information for Linux or POSIX.

If the application was started with a path, you might retrieve it as
the arg[0] parameter of main().

If not, you have to search the path for an application with the correct
name. I don't think there is a standard function to perform this. If I'm
wrong, I very much want to know the name of the function, since it would
be useful :)

On Linux, it is possible to heck in the /proc filesystem. There exists a
symbolic link:
/proc/<process_id>/exe -> /my/running/binary
That will specify which binary that is running.

It may also be accessed as:
/proc/self/exe -> /my/running/binary
to avoid the extra trouble of retrieving process id and dynamically create
the path to the symbolic link.

[Dev-C++] Cant use Ctrl-Z or Ctrl-D in DOS window

[Niklas W. <nik...@te...>]

Hello,
 
When I do like this
 
While(cin >> number)
{
..
}
 
I would like to be able to end this while loop by pressing Ctrl-Z or
Ctrl-D.
But I can't when I create a dos window in DevC++.
 
Can anyone help?
Maybe some other key combination or maybe some setting in DevC++?

Niklas
 

RE: [Dev-C++] How to get application directory?

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

To read contents of a link on Linux, just call
readlink()

To reatrieve information about a link - instead of the file it points to,
use lstat() instead of stat().

Re: [Dev-C++] How to link with a dll?

[<gen...@ya...>]

hey,
 
i think you're way over my head with this one. however, what i think is: you probably never included the <windows.h> header file, or else how on earth could it say it doesn't understand 'CALLBACK'.
 
my guess is you probably built the application with the Borland equivalent of AppWizard. sorry, man, for now, dev-c++ only compiles native Win32 programs. application layers like VCL, OWL, and MFC have very little chance of working when built with dev-c++.
 
if you want to learn Win32 coding 'the hard way', you can try using the tutorials at http://winprog.net. or you can use a toolkit like wxWidgets (www.wxwindows.org) or the FOX toolkit (www.fox-toolkit.org).

[Dev-C++] How to link with a dll?

[Bo F. <bof...@ma...>]

Hi all.

I've just installed dev-cpp on my WinXP. I want to move a program I made =
with a Borland IDE to dev-cpp and here's my problem:

The source includes mmsystem.h and I know I have to link to the =
library...but where is it? I figure it's a dll (either the one in =
c:\windows\system or c:\windows\system32). I tried a few things, but no =
luck.

Below is the compile log, and as you can see, the first two ( =
(1)compiler is g++ and (2)paths looks ok) of the "basic 3" should be ok. =
:-)

Compiler: Default compiler

Re: [Dev-C++] How to get application directory?

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

If the application was started with a path, you might retrieve it as
the arg[0] parameter of main().

If not, you have to search the path for an application with the correct
name. I don't think there is a standard function to perform this. If I'm
wrong, I very much want to know the name of the function, since it would
be useful :)

On Linux, it is possible to heck in the /proc filesystem. There exists a
symbolic link:
/proc/<process_id>/exe -> /my/running/binary
That will specify which binary that is running.

It may also be accessed as:
/proc/self/exe -> /my/running/binary
to avoid the extra trouble of retrieving process id and dynamically create
the path to the symbolic link.

Re: [Dev-C++] How to get application directory?

[<sub...@ar...>]

What I actually wanted is the directory where the binary application is stored...
Anybody knows how to get it?

Thanks again,

Re: [Dev-C++] protected and private in c++ classes

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

I wrote terse, but was actually correct:
"Private is only for methods of the class" as in: privately declared
member fields and methods may only be accessed by members of that class :)

I didn't say that only methods may use private. I meant that only methods
of that class may acccess any private fields, methods, constructors, ...

I don't think it's correct to say that methods are usually public. There
are just as large reasons to keep methods protected or private as there
are to keep variables protected or private.

I think you missed a bit about inherritance of access rights to protected
fields. The protected declarations will continue to be protected for
multiple generations, unless one of the inherritances stops it, i.e.

class A {
protected:
    int a;
};

class B : public A {
    // a still protected
};

class C : public B {
    // a still protected
};

class D : private C {
    // a now private because parent C is private!
};

class E : public D {
    // No longer access to field a, since class D
    // declared it's parent relation as "private".
};
