I did not see right?


You generate a random number then you compare this with the inputed serial:



004841D6 E8 79F0F7FF CALL <RDG_Simp.System.Random> //Generate random number
004841DB 8D55 94 LEA EDX,DWORD PTR SS:[EBP-0x6C]
004841DE E8 9567F8FF CALL <RDG_Simp._Unit3.IntToStr> //Integer to string conversion
004841E3 8B55 94 MOV EDX,DWORD PTR SS:[EBP-0x6C] //Load the result in EDX
004841E6 58 POP EAX //Put in stack inputed serial
004841E7 E8 7418F8FF CALL <RDG_Simp.System.@UStrEqual> // Compare inputed serial with a random number

I have deleted the program...


:sorry:


I saw somewhere the string "Congratulations" loaded.


Just change the loaded registers from wrong to right and that's it.


Even i copyed the the compared serial from the buffer where the good boy appeared when i have inputed in the box it shown wrong serial so i guess there is involved a random factor.
