]]> The GCC compiler (or G++) does not always work with our source code files just as we would expect it to. This specially happens when there are special characters in our files (the ones with ASCII codes higher than 127).

Take the following program as a sample (the strings are written in spanish):

#include <iostream>
using std::cout;
using std::cin;
using std::endl;

#include <string>
using std::string;

int main()
{
	string sDummy;

	cout << "Por favor ingrese su contraseña: ";
	cin >> sDummy;

	cout << endl;
	cout << "Su contraseña es inválida, por favor verifíquela e inténtelo nuevamente. Ha ingresado: '" << sDummy << "'." << endl;

	return 0;
}

Let’s compile it… 

g++ TestChars.cpp -o TestChars.exe

And execute it… We can easily imagine the output… But… This is what we get:

Por favor ingrese su contrase±a: contraseña

Su contrase±a es invßlida, por favor veriffquela e intTntelo nuevamente. Ha ingresado: 'contraseña'.

Notice that the string that we’ve just typed (“contraseña”) gets correctly printed, while the ones hard-coded in the program don’t.

So… What can we do?

Well, there are some compiler command line parameters ready to help us… They are the finput-charset and fexec-charset command line arguments…

Both take as additional parameter a charset name from the ones supported by the compiler…

For the interested ones, here is the output of the charsets supported by the library that GCC uses to make the conversion… They may not be the same on every system…

# iconv --list
The following list contain all the coded character sets known.  This does not necessarily mean that all combinations of these names can be used for the FROM and TO command line parameters.  One coded character set can be listed with several different names (aliases).

The first parameter, finput-charset, is the charset used to read the source code files… The second one, fexec-charset, is the used to store the strings and character constants in the executable file, so they will be shown correctly while running…

So, assuming you’re writing your source files in iso-8859-1 (the most common charset on Windows platforms) and want to show them while running in cp437 (the DOS console charset), we could call the compiler like this:

g++ TestChars.cpp -o TestChars.exe -finput-charset=iso-8859-1 -fexec-charset=cp437

And what do we expect to get? :)

Por favor ingrese su contraseña: contraseña

Su contraseña es inválida, por favor verifíquela e inténtelo nuevamente. Ha ingresado: 'contraseña'.

Everything worked just the way we expected! :)

Now, finally, I’ll show how to configure these command line options for the wxDev IDE…

First of all, I must say there are two ways to set compiler options: global options and project options… As you may imagine, the first ones are applied to every compiled project, while the latter just get applied to the currently opened project (they are set in a per project basis)…

To set the parameters in the global compiler options you must got to the Tools menu and then open the Compiler Options item…

Main_Menu_EN

After that, you simply enter the following string (the parameters) into the “Add the following commands when calling compiler” box:

-finput-charset=iso-8859-1 -fexec-charset=cp437

If there are already other parameters configured, you should append them…

Main_Compiler_Options_Filled_EN

They will be sent to both the C compiler and the C++ compiler…

The other alternative is to set the same parameters in the project options…

First, we open the project options… Either going to Project->Project Options or right clicking the project and going to “Project Options”…

Project_Menu_EN

Then, we go to the Parameters page and paste the parameters string in the two compiler boxes… Both parameters can be entered either in a single line or broken apart… Just as before, if there are already other parameters configured, you should append them…

Project_Options_Parameters_Filled_EN

Whell, that’s all… Most IDEs will have similar options!

  1. Attendance Control (wxWidgets Version)
  2. Simple C++ List Class
  3. Simple C++ String Class
]]> “Attendance Control” is a console application made as an exercise to integrate the different C++ concepts taught in class up to the middle of the year.

The main objective is to be able to develop a employee attendance control which records the times (and justifications, if corresponding) of each time the employees arrive, go to lunch, return from lunch and go back to home.

Sistema de control de asistencia de personal
--------------------------------------------

DNI:

The complete wording says:

Develop an employee attendance control system (for later verification of absences and late arrivals with their corresponding justifications) and its managemente private part (user registration and gathered data visualization).

The main screen must staywaiting for ID [DNI] and password.

There must be a preset admin user with DNI = -1234 and Password = prueba.

In case of being an administrator user, you’ll be able to access the management part, with the following options:

1- Alta de usuario [New user]
2- Lista de usuarios (datos adquiridos) [User list (gathered data)]
3- Salida a archivo [Output to file]
4- Cerrar la aplicación [Close the application]
0- Volver a la pantalla principal [Back to the main screen]

Otherwise, it will be asked which kind of action are you about to do (Arrival [Ingreso], return to home [Salida], lunch [Salida a almuerzo] or return from lunch [Retorno de almuerzo]) and its justification in case it corresponds, and they will be recorded along with the current time in a “Events” record of the corresponding user.

The user required data is:
DNI [ID]
Nombre completo [Full name]
Contraseña [Password]
Si es administrador [Whether it is administrator]
Eventos relacionados [Related events]

It’s desired to use as a base the class “PersonaBasica” [Basic person] which has already been developed by the IT department, whose header file “PersonaBasica.h” is attached below:

#include "String.h"
#include <iostream>

class PersonaBasica
{
	String m_sNombreCompleto;
	long m_nDNI;

public:
	//Construcción
	PersonaBasica() { m_nDNI = 0; }

	//Encapsulaciones
	long DNI() const { return m_nDNI; }
	void DNI(long val) { m_nDNI = val; }

	String NombreCompleto() const { return m_sNombreCompleto; }
	void NombreCompleto(String val) { m_sNombreCompleto = val; }
};

std::ostream& operator<<(std::ostream& oStream, PersonaBasica& rpPersonaBasica);

Note: the lengths of the data to be registered is completely unknown and rumors are circulating that the users are used to write pretty elaborate justifications.

When you first start the program, you can only log in as admin (-1234:prueba)…

Sistema de control de asistencia de personal
--------------------------------------------

DNI: -1234
Contraseña: prueba
Usuario "Administrador" reconocido.

Presione una tecla para continuar...

Then, you’ll get to the administration menu:

Sistema de control de asistencia de personal (ADMNISTRACION)
------------------------------------------------------------

1- Alta de usuario
2- Lista de usuarios (datos adquiridos)
3- Salida a archivo
4- Cerrar la aplicación
0- Volver a la pantalla principal

Ingrese la opción deseada:

The next step should be registering the different users using the first option:

Sistema de control de asistencia de personal (Alta de usuario)
--------------------------------------------------------------

DNI: 12345678
Nombre completo: Pedro Gutierrez
Password: 123bbb
Administrador [1 = Sí/0 = No]: 0

Persona agregada satisfatoriamente.

Presione una tecla para continuar...

After that, they’ll be able to sign in themselves:

Sistema de control de asistencia de personal
--------------------------------------------

DNI: 12345678
Contraseña: 123bbb
Usuario "Pedro Gutierrez" reconocido.

Presione una tecla para continuar...

So they’ll get into the attendance screen to record their actions:

Asistencia de "Pedro Gutierrez"
-------------------------------

Tipo de asistencia:
        1- Ingreso
        2- Salida
        3- Salida a almorzar
        4- Vuelta de almorzar
Selección: 1

Justificación (si corresponde): Llegué tarde porque había
corte de calles.

Evento agregado satisfactoriamente.

Presione una tecla para continuar...

Each of them ’till they go back to home…

Asistencia de "Pedro Gutierrez"
-------------------------------

Tipo de asistencia:
        1- Ingreso
        2- Salida
        3- Salida a almorzar
        4- Vuelta de almorzar
Selección: 2

Justificación (si corresponde): Me voy más temprano porque
tengo que llevar a mi hijo al médico.

Evento agregado satisfactoriamente.

Presione una tecla para continuar...

When any administrator wants to watch the full listing of users and actions, he simply logs in and goes to the second option of the administration menu:

Sistema de control de asistencia de personal (Lista de
usuarios)
------------------------------------------------------

DNI: -1234
Nombre completo: Administrador
Password: ********
Administrador: 1
Cantidad de eventos: 0
Eventos:

[Esta persona no posee eventos]


DNI: 12345678
Nombre completo: Pedro Gutierrez
Password: ********
Administrador: 0
Cantidad de eventos: 4
Eventos:

Hora: 28/07/2009 14:13:27
Tipo: Ingreso
Justificación: Llegué tarde porque había corte de calles.

Hora: 28/07/2009 14:14:23
Tipo: Salida a almorzar
Justificación:

Hora: 28/07/2009 14:14:44
Tipo: Vuelta de almorzar
Justificación:

Hora: 28/07/2009 14:14:52
Tipo: Salida
Justificación: Me voy más temprano porque tengo que llevar a
mi hijo al médico.

Presione una tecla para continuar...

If he wants, he can save that information to a file by using, instead, the third option:

Sistema de control de asistencia de personal (ADMNISTRACION)
------------------------------------------------------------

1- Alta de usuario
2- Lista de usuarios (datos adquiridos)
3- Salida a archivo
4- Cerrar la aplicación
0- Volver a la pantalla principal

Ingrese la opción deseada: 3

Ingrese la ruta del archivo a guardar: c:asistencia.txt
Archivo guardado satisfactoriamente

Presione una tecla para continuar...

Finally, he can close the program by going to the fourth option (losing all the data)…

Sistema de control de asistencia de personal (ADMNISTRACION)
------------------------------------------------------------

1- Alta de usuario
2- Lista de usuarios (datos adquiridos)
3- Salida a archivo
4- Cerrar la aplicación
0- Volver a la pantalla principal

Ingrese la opción deseada: 4
Saliendo de la aplicación...

Presione una tecla para continuar...

That’s the idea of the application…

Now I’ll leave the links for the ones who don’t want to solve it themselves (or the ones who just want to run it and watch it work).

The code is portable between Linux and Windows (I’ve tested it myself on both platforms and it worked seamlessly).

It’s been developed, compiled and tested using wxDev-C++ for Windows with the MinGW compiler (included in the bundle). In Linux, it was compiled using the GNU GCC compiler.

Update: minor bug in String.cpp fixed => version 1.01

Wake-On-Lan (WOL) Tool v1.0 by NeoEGM
http://www.neoegm.com/software/wake-on-lan/
-------------------------------------------

Usage: wol 

Wakes the computer with the specified MAC address.

Accepted MAC address formats: 01-4B-8E-00-52-A1
                              01-4b-8e-00-52-a1
                              01:4B:8E:00:52:A1
                              01:4b:8e:00:52:a1
                              014B.8E00.52A1
                              014b.8e00.52a1
                              014b8e0052a1
                              014B8E0052A1

You have to configure the remote computer (the one which will be powered on) to support the Wake-On-LAN feature. This is done in the CMOS settings looking for the “Power/ACPI” settings or something like that.

Then, you have to find out the MAC Address (sometimes called “Physical Address”) of the network adapter connected to the LAN. On Windows it’s done doing this from the console:

C:\>ipconfig /all

Windows IP Configuration

   Host Name . . . . . . . . . . . . : mypc1
   Primary Dns Suffix  . . . . . . . :
   Node Type . . . . . . . . . . . . : Unknown
   IP Routing Enabled. . . . . . . . : No
   WINS Proxy Enabled. . . . . . . . : No

Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : Marvell Yukon 88E8056
PCI-E Gigabit Ethernet Controller
   Physical Address. . . . . . . . . : 00-1F-C2-14-B3-F4
   DHCP Enabled. . . . . . . . . . . : No
   IP Address. . . . . . . . . . . . : 192.168.0.1
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.0.254
   DNS Servers . . . . . . . . . . . : 192.168.0.254

In this case, it’s “00-1F-C2-14-B3-F4″, so the tool can be used like this:

C:\>wol 00-1F-C2-14-B3-F4

Wake-On-Lan (WOL) Tool v1.0 by NeoEGM
http://www.neoegm.com/software/wake-on-lan/
-------------------------------------------

Wake-up packet sent to MAC address 00-1F-C2-14-B3-F4.

There are some restrictions that apply to the hardware, but a summary may be: the motherboard must support the “Wake-On-Lan (WOL)” feature and the NIC (network adapter) must have a wire called with that name connected to the motherboard. If the motherboard of the computer you want to power on is not so old and has an integrated (on-board) Ethernet card, then it’ll probably work.
