    I found something....
    Program has real-time checking;When you enter any char
    program checks the lenght!
    Here is piece of code where it checks for it...

    * Reference To: MSVBVM50.__vbaLenBstr, Ord:0000h
    |
    :00412F57 E888E2FEFF Call 004011E4 => GET LENGHT

    * Possible Reference to String Resource ID=00001: "Thank you for registering"
    |
    :00412F5C 6A01 push 00000001
    :00412F5E 894580 mov dword ptr [ebp-80], eax
    :00412F61 5E pop esi

    * Possible Reference to String Resource ID=00002: "Sorry, invalid code!"
    |
    :00412F62 6A02 push 00000002
    :00412F64 8BDE mov ebx, esi
    :00412F66 5F pop edi

    * Referenced by a (U)nconditional or (C)onditional Jump at Address:
    |:00412FDB(U)
    |
    :00412F67 663B5D80 cmp bx, word ptr [ebp-80]
    :00412F6B 7F70 jg 00412FDD => IF LENGHT IS 6 THEN DO SOMETHING

    Haven't time to analyze the code, must learn for school :(
    EB, I think that helps you...

    PS Try put bp on msvbvm50!__vbalenbstr!
    Bye,
