To work with external power supply, Is there any necessity to connet VB (pin3) a 3.3 volt something like that ? I mean, should i connect pin3 to 3.3 Volt? (I won't use RTC)

You must connect power to P2 (second pin). Then your program should run as expected.
How are you powering it? Which voltage, which pin?
