Just for the record, this is the way I managed to populate the array
with native types:
nsCOMPtr<nsIMutableArray> myMutableArray =
do_CreateInstance(NS_ARRAY_CONTRACTID);
// C strings
char *cstrTest = "anything";
nsCOMPtr<nsISupportsCString> strArg;
argStr = do_CreateInstance(NS_SUPPORTS_CSTRING_CONTRACTID, &rv);
NS_ENSURE_TRUE(strArg, NS_ERROR_FAILURE);
argStr->SetData( nsCString(cstrTest) );
rv = myMutableArray->AppendElement(strArg, PR_FALSE);
NS_ENSURE_SUCCESS(rv, rv);
// Int16 (short)
PRInt16 iNum = 0;
nsCOMPtr<nsISupportsPRInt16> shortArg;
shortArg = do_CreateInstance(NS_SUPPORTS_PRINT16_CONTRACTID, &rv);
NS_ENSURE_TRUE(shortArg, NS_ERROR_FAILURE);
shortArg->SetData(iNum);
rv = myMutableArray->AppendElement(shortArg, PR_FALSE);
NS_ENSURE_SUCCESS(rv, rv);
If somebody knows a less convoluted way of achieve the same, please
let me know
