| main 06. Jan 2009 | If you generate the number in the same proc as you do the check, there is not much room for any other code like printing the password. Is this intended? |

| costy 07. Jan 2009 | I successful removed the nag and the password is displayed in the textbox on the bottom but I removed the New Form2().Show line. I don't know why but reflector gives me some problem with it... |
| indomit 12. Mar 2009 | We know the password only when the user clicks the button. We can't pre-specify a password, because we didn't know when the user clicks the button. As password generated from system time. Only thing we can do is to store system time at first pre-generation and restore it before new generation. But I do not know this is possible to catch/leave the time in right moment. |
| indomit 12. Mar 2009 | Ha-ha. Else we can wait about 50days, after user click when TickCount will be the same again :) :lol: So only way I see is to repalce(patch?) Random() to Random(saved_tickcount). Is this allowed? =) |
| ReWrit Author 12. Mar 2009 | yep, as long as it show the correct password as your solution does its ok =) |
