>What kind of error would you not want to cause your program to stop? The error is a sign that there is a problem, I would think you would rather it die sooner than later before more problems may occur. Unless you are throwing the error yourself (in code), it is unforeseen. How would you know what conditions you don't want to catch?

Well, for example, if a file is opened EXCLUSIVELY by a sysadmin for cleanup or for any other reasons and a user tries to write some info to it after hitting the OK button. I'd like for my program to say: "The file is currently being used, please try again later!" for example and return to the form being just opened skipping the rest of the code in the OK button.
