This class, written by James Boyd, is a logger/error handler that does many things:
1.) Displays errors to users when they occur
2.) Records the activities of the application as various subroutines get executed
3.) When a run-time error happens, it can fire off an e-mail to the developer, replete with
routine name, error description, and even a dump of the app's execution stack at that point
4.) It can also maintain a text file which has the application's execution stack history
There are two ways of using this error handling/logging class:
1.) Use it just for error trapping
2.) Use it also for logging the execution path of an application. Since it captures the exact occurrence of a logged activity down to the THOUSANDTH of a second, it can be extremely useful for performing performance/efficiency analysis on subroutines.

Great job, James but one problem the email-prog (outlook) don't start up a missing link..? Can you help me ?? (If this comment was disrespectful, please report it.)
Good code ... but the code doesn't consistently work with different long messages. I can send all of the pieces of one message in 100 char pieces but to send it at once it fails on 244th character. Coming from righ it fails on 176th. This should be tested on large strings to determine if certain characters, combination of characters or character + string length cause it to fail. Are there any other characters to trap for? (If this comment was disrespectful, please report it.)
thx James for reply (via email) - API isn't too robust but knowing limitations helps create a work-around. Test return code - if it is 2 (failure) slim down message and try again. James says rev 2 in the pipeline. 5 for effort. (If this comment was disrespectful, please report it.)
Excellent code, but as some others have reported the email program (Outlook Express in my case) fails to open up. Any fixes ? Thank you. (If this comment was disrespectful, please report it.)
Does anyone know about using Lotus Notes to run the email portion of this code? Any info would be greatly appreciated. (If this comment was disrespectful, please report it.)
When opening the default email-program using the Shell command you have to make sure that the email-body isn't too long. If it is too long the email program will not open!!! I don't know the reason for it. Maybe somebody else knows?! (If this comment was disrespectful, please report it.)

I am using Outlook express 6, and it puts the WHOLE email body, subject, etc in the TO field..! (If this comment was disrespectful, please report it.)

Very good code, just one point: on my computer the whole email is put in the TO field. To avoid that, simply put "?" between email address and subject instead of "&" if there are no CCs, and it works great ! (If this comment was disrespectful, please report it.)
Could it automatically send email to the developer ? (If this comment was disrespectful, please report it.)
