Hola a todos,
Dispongo de una aplicación muy senzilla. Tengo un diálogo en el cual aparece un editbox. A este editbox le he de escribir caracteres chinos. Esto ya lo he conseguido, pero ahora me gustaría obtener el valor hexadecimal en la codificación gb232 o en su defecto en big5 de cada uno de los caracteres que contiene el editbox.
En el diálogo dispongo de un boton de aceptar y otro de cancelar que son los que venian por defecto y simplemente sirven para salir de la aplicación. Luego dispongo de un editbox y de un boton que cuando lo apreto ejecuta la rutina onbutton1.
El código és el siguiente:
Código:
// unicodeDlg.cpp : implementation file
//
#include "stdafx.h"
#include "unicode.h"
#include "unicodeDlg.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

No se si es correcto o no pero me gustaría obtener el valor en hexadecimal del símbolo en la variable a, de tal modo que si luego quiero dibujar el simbolo correspondiente a ese valor lo muestre correctamente de nuevo.
De momento obtengo valores como el de a=38463..pero para nada es correcto.
Alguna idea? muchas gracias!
