Lưu ý bạn StormV5 bị lỗi khi add xong thư viện nhưng không chạy (build ko có lỗi nhé), cụ thể lỗi hàm này: vprintf( szFmt, args );
ai bị thì bỏ hàm này đi. Riêng tui không bị phát sinh 1 lỗi nào khi add, cảm ơn bạn StormV5 đã chia sẽ, ai bị lỗi nào khi add thư viện thì tiếp tục post lên để mọi người giải quyết khi gặp và mọi người giúp đỡ.
