Ciao, sto cercando di eseguire il seguente esempio relativamente a xerces c++(scaricato da http://xerces.apache.org/xerces-c/samples-3.html), ho inserito le classi da testare in un progetto console win32 di visual c++ 2008 express edition. La classe principale è la seguente:
nessun problema relativamente alla compilazione, i problemi si riscontrano in due casi:codice:#include "stdafx.h" #include "SAXCount.hpp" #if defined(XERCES_NEW_IOSTREAMS) #include <fstream> #else #include <fstream.h> #endif #include <xercesc/util/OutOfMemoryException.hpp> // --------------------------------------------------------------------------- // Local helper methods // --------------------------------------------------------------------------- void usage() { XERCES_STD_QUALIFIER cout << "\nUsage:\n" " SAXCount [options] <XML file | List file>\n\n" "This program invokes the SAX Parser, and then prints the\n" "number of elements, attributes, spaces and characters found\n" "in each XML file, using SAX API.\n\n" "Options:\n" " -l Indicate the input file is a List File that has a list of xml files.\n" " Default to off (Input file is an XML file).\n" " -v=xxx Validation scheme [always | never | auto*].\n" " -n Enable namespace processing.

1. se eseguo il debug ricevo il seguente output:

Il programma '[4688] prova4.exe: Nativo' è terminato con il codice 1 (0x1).
2. Se eseguo avvia senza eseguire debug mi viene visualizzata la console con il contenuto della funzione usage() presente nel codice sopra citato che termina con la seguente stringa "premere un tasto per continuare" ma non mi permette di eseguire alcuna operazione, ma alla pressione di qualsiasi tasto (anche -) la finestra viene chiusa.
Accetto suggerimenti..grazie..ciao ciao
