What is "ceptcha"? What is "plese"? What is "i"? What session, for goodness sake? What's the application type? Why not database?

Please tag correct technologies and explain a bit.
Don't forget to mention what application you are developing ....

my1, oh my god! I just imagined a job interview: the question comes from the interviewer and then the interviewee starts begging for the answer. :-)
Lets say ha passed the interview, 1st day at work, begging around for lines of codes and functions at your workmates... Not extreme programming but beggar programming. :-D

pandya purvang 31-Jul-12 7:27am

sir what are you saying ......is it related to me???

pasztorpisti 31-Jul-12 7:30am

I hope not. :-)

pandya purvang 31-Jul-12 7:33am

lol, i also hope that....perhaps this seems u r very experienced person in This field......and i m with no experience thats you are talking like this....anyway i can take it positively and works on it...:D

pasztorpisti 31-Jul-12 7:37am

The problem is that your question is too easy and smells like homework. If we answer it then we make something wrong because we help you to a way on which you never become a programmer. Sir, maybe you don't even want to become one but correct me if Im wrong! :-)

pandya purvang 31-Jul-12 7:40am

Sir totaly agree......thats why i m saying that i will take it positively......

pasztorpisti 31-Jul-12 7:41am

OK, piece! :)

pasztorpisti 31-Jul-12 7:39am

by the way, what are you working on?

pandya purvang 31-Jul-12 7:41am

sir you were talking already in above one of the comment i m interviewee freshers and looking for job

pasztorpisti 31-Jul-12 7:47am

Then at least you have some willing to do this. :) Taking a look at your comments below under the questions I guess you should first read 1-2 beginner books on programming in your favorite languages. I assure that you won't ask questions like this after reading 1 beginner book in your favorite language. I'm sad to say but if you ask questions like this its unlikely that you get a job from a serious employer. Lets go and read a beginner book, and try the examples you find in the book in practice!

Solution 1

Some pseudocode:

passwordCorrect = false;
attemptCount = 0;

while ((attemptCount < 3) & (passwordCorrect == false))
{
   pwd = getPassword
   attemptCount++
   passwordCorrect = isPasswordCorrect(pwd)
}

if passwordCorrect != true
{
  displayErrorMessage
  QuitOrExitOrWhateverElseHere
}

Solution 2

what to do with loops..?

you can use a static variable to store number of attepts
and in login button click event check its value, if exeeds three show CAPTCHA..
dont forget to increment its value...

C#

private static int attempt = 0;
protected void loginBtn_Click(object sender, EventArgs e)
    {
      attempt++;
      if(/*check password */)
      {
      //login success
      }
      else
      {  
        if(attempt>3)

okk sir thanks but what should be the code in that if(/*check password*/) condition if u will provide the code here then it should be very easy for me

Albert Holguin 31-Jul-12 13:00pm

It's simple, read the input that the user gave you (from whatever source) then compare it against your known password. The password should probably be kept on an encrypted file somewhere.
