Print ID for all known classes.

CAmvConn* AmvConn;

CAmvClassFilter* class_ptr;

TCHAR id_buf[CLASS_ID_LEN+1];

for (class_ptr = AmvConn->ClasssFilters->First(&ret_stat);

class_ptr != NULL && ret_stat.status == COR_SUCCESS;

class_ptr = AmvConn->ClassFilters->Next(class_ptr,

&ret_stat))

{

_tprintf(_T("%s\n"), class_ptr->ID(id_buf));
