Creating a program

[asdf001]

How will i do this in a programming language

I wanna create a cracker for a game that will try a 4 digit number from 0000 to 9999

So it has to do this
put the login id an password
try 4 pins
hit cancel
type in your id and password and pin
so it can reset the tries
hit the back button
and put login id and do 4 pins etc..

view at your own risk: im not sure if im suppose to respond to this but,

Spoiler:

a macro program?

A macro might work if it's for windows and you use a macro language that can sent key/mouse events to another program.

Really though this sounds like a craxcking attempt, and we discourage such things here.
