      It worries me that we are spiralling into some kind of recursive software hellhole:

      void WritePoorCode()
      {
      bool stuck = true;

      if (stuck)
      {
          GetHelpFromAnotherMuppet();
      }
      

      }

      void GetHelpFromAnotherMuppet()
      {
      WritePoorCode();
      }

            I've just read an article that included this little gem

            ://it checks it contains 11 char (dd/MMM/yyyy) 
            if (Convert.ToInt16(chkdate.Length.ToString()) != 11) 
            { 
              //if it does not have 11 char then it will return false 
              return false; 
            }
            

            I really don't know where to start (and yes, chkdate is a string).

            why do you rely on an implicit Int16-to-Int32 conversion? I would recommend an explicit cast to make things more clear. :)

              That's right. You can't have enough casting and converting going on.

                Rediculous .. you need to convert both to decimal to guarentee precision and get rid of that pesky implicit conversion ...

                if(Convert.ToDecimal(Convert.ToInt16(chkdate.Length.ToString())) != Convert.ToDecimal("11")) {
                doNoRealValidationCheck_NeverLearnRegex();
                }


                I'm largely language agnostic

                    Except you forgot to convert the char types to some int type to ensure it would be a numeric comparison. :rolleyes: :)

                      Not so fast, your code does not work while his does. ;P [Hint] Your code will not return false for strings of length 1, 10, 101, etc.

                            I think this improves the code a lot… Extra precisions and conversions to make sure we're getting exactly what we want. :) ((Decimal)Convert.ToDecimal(chkdate.Length.ToString()) != (Decimal)Convert.ToDecimal(((Decimal)(11.0000000000000000000000000000)).ToString())).ToString() == Boolean.TrueString; The optimizing JITter is going to have fun with this one…

                              You left out the string.compare call with the ignore case option, and specifying the CultureInfo on the ToString calls. :doh:


                              This blanket smells like ham

                                The rule of three: "The first time you notice something that might repeat, don't generalize it. The second time the situation occurs, develop in a similar fashion -- possibly even copy/paste -- but don't generalize yet. On the third time, look to generalize the approach."

                                  I've just read an article that included this little gem

                                  ://it checks it contains 11 char (dd/MMM/yyyy) 
                                  if (Convert.ToInt16(chkdate.Length.ToString()) != 11) 
                                  { 
                                    //if it does not have 11 char then it will return false 
                                    return false; 
                                  }
                                  

                                  I really don't know where to start (and yes, chkdate is a string).

                                  Is this what they call optimized code? :confused:

                                    For checking whether the string contains a valid date the code is crap. (SCNR) This shows what the results of "high level" programming languages are. X|

                                      Idiot developers who shouldn't be let anywhere near a keyboard without being wired up to the mains and given a shock everytime they produce crap like this.

                                        It is now. It was removed because it was so bad and about the best comment against it was that it was complete and utter rubbish.

                                          It should have been 'An Article of Horror'. It is bad that it was removed and CP deprived many of a viewing pleasure. :mad:
