This question is for shogi...

Hi, one more question.  How do I have it check to see if the last ten numbers are the ten numbers in regnum.dat / the amount of digits in the username (Edit2)? This will be added to the end of my edited codes.  For example if the number in regnum.dat is 250000000000 and the number of digits in the username (Edit2) is 5 the last ten digits will be 50000000000.

thanks,

steven

Do not know if I understand you question, but I give you a sample code how to valid ...  I make my example with 11, because in your question you have 12 digits and it's seen you want the last 11.

Don't forget I'll not able to answer after sunday...for 1 week!

example :

// 1 edit1 field and 1 button to valid

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    int ValidationOk = 1;

    // here I will make a constant, but this number come from you file
    char ValidNumber[15] = "250000000000";
    // Here I give an example with a fixe number of chartere in the field
    char Text1[30];
    Edit1->GetTextBuf(Text1, 30);

    // testing size
    int SizeEdit = (Edit1->GetTextLen()) -1;
    int MAX_VALID = 11;   // 11 last number I want to valid
    int SizeValidNumber = strlen(ValidNumber) - 1;

    // validation
    for (; MAX_VALID>0 && SizeValidNumber>=0 && SizeEdit >= 0;
         MAX_VALID--,SizeValidNumber--, SizeEdit--)
    {
      if (ValidNumber[SizeValidNumber]!= Text1[SizeEdit])
         ValidationOk = 0;
    }

    if (ValidationOk && MAX_VALID==0)
         Application->MessageBox("I have a valid number",
                                  "Validation", MB_OK);
    else
         Application->MessageBox("Error: I don't have a valid number",
                                 "Validation", MB_OK);


}

Ok I do not think u understand my question.  I will ahve my program randomaly generate a number (ten digits long) and save it in regnum.dat.  What I need you to do is make some codes up (for me to add to the end of the current validation codes) that will check to see if the last ten digits (in Edit1) are the same digits that are in regnum.dat devided by the number of digits in Edit2.  So basically you are taking a ten digit number and deviding it by the number of digits (charecters) in Edit2.  By doing this is will be a lot harder for someone to guess the shareware registration code.

Take a look to the code... if your Edit1 is my Edit1 and your number in your file it's my ValidNumber.  And MaX_VALID it's your max characters you want to valid.  My validation start to the end of Edit1 (your big validation code).

Here my understand:

in regnum = 4444444444

if in Edit2 I have 2 digits

regnum/2 = 2222222222

And you want that number

(2222222222) == The_Last_10_digit_of_my_MASK

it's that???.. feel sorry I have 48 hours without sleep, and I think my brain it's somewhere else :-)

If you need to speak me directly I'll be on IRC, with the same nickname shogi

Ok what I need is someway to see if the last 10 digits entered to Edit2 = regnum.dat (there will be 10 digits in it) / the number of charecters in Edit1.  Do you understand????  I also need this ASAP.  My program will be on the market March 1 and need it to be completed!
