    Looks to me like the original programmer was too lazy to handle an exception, and another programmer came along and added the helpful "Not good!" comment, and left it like that. I don't know which programmer to hate more. Five bucks says that account.Save() has a return value indicating success.

      I'm trying (in vain so far) to think up any scenario where the context around this might make this o.k. For example, something like:

      int pageIndex = 0;
      try {
      pageIndex = int.TryParse(Request[pageNum])
      } catch (Exception e) {
      Logger.info("Page Index of " + Request[pageNum] + " invalid, using " + pageIndex.ToString());
      }

      (Of course, I'd use Int.TryParse instead and null-check the request variable) But, you get the idea--some scenario where you can continue to operate with default data given an unexpected condition. I can't think of any situation where the missing context makes it o.k. to swallow an exception trying whatever a Save operation does.

      I can think of situations where it might be appropriate to do something like that. For instance, suppose you are implementing a "like" button or something similar. It's not critical that it works and let's assume that it's unreliable for reasons beyond the programmer's control, like maybe it depends on an external service which is not always available. So in that case maybe it's OK to swallow the exception since it's not unusual and nothing will really break if it fails, so you just silently fail and the user can try again if they want. There aren't many situations like this in programming though, and you still should probably log the exceptions. I'm pretty sure that something like account.Save() is a bit too important to treat this way, though.

        Well if saving doesn't work now, it could work later... ;P

          If in the account class the Save method looked like this there might be a scenario where the eating of exceptions is fine: try { // Some code to save the record to the db .... } catch(Exception ex) { logger.Log(ex); throw; }

            Oh, yea! Really user friendly. I ask to save, it works fine. Except I don't know if it worked or not. So now I've got to retrieve the data. If it is retrieved, fine, it worked. If not, then I get to save again and then check again and...

              I've read somewhere that this code is equivalent to:

              try
              {
              // account.Save(); // If this can fail silently, then why bother?
              }
              catch { ; } //Not good!

              Then again, a LART would be more educational. ;)

                  Man, people split up because of a 'like' button. You don't 'like' in time -- you loose. It IS crtical. :rolleyes:

                    That's OK, people who care about "like" buttons should be ostracized anyway. On a side note, if I hear someone at my organization say one more time that our site needs to be more like Facebook, I'm going to garrote myself with a Cat5 cable.

                      Well, CP seems to go in that direction, too... It is a matter of time when it becomes "CodeBook". If it makes you feel better, I can vote you down :laugh:

                            I think exactly opposite. While I'm not a huge fan of a facebook, this particular feature is fine for me. Whereas I do dislike various things, a non-existance of downvoting mechanism forces me to express the dislike in a commentary (hopefully constructive). No downvoting makes the website more positive, which is a desired feature for a social network. We all have enough univoters in the real life... Anyway, there are a lot of "hatred groups" on FB. Giving a 'like' to them is a way to express hatred, if you really need to.
