Just a matter of bruteforcing it.

This one was pretty easy to do. I first unpacked it using the .NET Unpacker (http://ntcore.com/netunpack.php) and then used IDA to find the hex offset of the click method. I nop'ed the calls to get_Length() and turned that brtrue to br so you could enter any length string. I then nop'ed the calls to the verification method and had it directly jump to the part where it sets flag = true. And that was pretty much it.
