["HERNAN LAGRAVA" <hernanjls@hotmail.com>]

Ok, asume wath is of type *char then


               CDBListView *listView = dynamic_cast<CDBListView *>(w);
	if (!listView) return;
	if (!dataDialog) return;

               char* IDPersona;
               int ixData;

               ixData = (int)listView->data();
	IDPersona = (char *)ixData ;

	printf("id: %s\n",IDPersona);  //  COMPILE BUT THIS LINE NOT WORK
