C++ Internet Connection Hack Problem

[scriptncoder]

So, for a while I have been trying to create a hack for Internet Connection, because my place only has one computer connected to an internet source. So I thought, maybe I could create a hack that tries every possible passcode combination possible. While every time an entire digit is completed, it adds another digit to be checked. I have tried keybd_event() and SendInput() but both go through each possible character and then after a while, it starts to spaz out. I need an explanation and another way to fix this problem. Thank you for your time.
