- ERROR LOG UNIT
- Copyright 1995
- By
- Bob Dalton
-
- INTRODUCTION:
- ------------
- One of the most frustrating things about being a door author
- is having to deal with the people who send you a message
- that the door program is not working but do NOT give me
- sufficient information on WHY it is not working. This unit
- will help you by providing an error.log when the program
- crashes or aborts for some reason. Just ask your door users
- to send you any error logs which might be generated by your
- program. This unit has helped me pin down, almost exactly
- at times, some of the bugs which rear their ugly heads in my
- doors on occassion. The ELOG.PAS code included in this
- archive is FREEWARE and can be used in any manner you want
- and without cost, but remains copyrighted to Bob Dalton,
- along with anything else in this package.
-
- REQUIREMENTS:
- ------------
- At this point in time the only requirements are that you must
- be using Borland Turbo Pascal version 6.0 or 7.0. I compiled
- the unit with Borland Pascal 7.0 Professional and know it
- works. I expect it will with TP 6.0 as well but can't guarantee
- it.
-
- Files Included
- --------------
- Below is a listing of all files for the ELOG.ZIP Package:
-
- ELOG.DOC - The text file you are reading.
- ELOG.PAS - The Error Log routines unit by Bob Dalton.
-
- Installation and Preparation for Use
- ------------------------------------
-
- 1. Move the archive package to a temporary directory and "unzip".
-
- 2. Before compiling the ELOG.pas unit be sure that your
- compiler knows where to find the listed units.
-
- 3. Add ELOG to the "Uses" portion of your program and call
- the procedures as needed and shown below. Only two lines
- in your main program code are required to make the unit
- work with your program.
-
- SaveExitProc:=Exitproc; <------ Must be first to make it work
- ExitProc:=@MyExit1; <------ Must be second to make it work
-
- 4. That's it! Enjoy and good luck.
-
- 5. Replace "uses DDPlus" with "Use DDPlusR" if you are using
- RipLink and also uncomment those portions of the ELOG.PAS unit
- which pertain to RipLink.
-
- 6. Make sure you include you save game procedure call in the
- places shown in the ELOG.PAS unit!
-
- 7. Still have questions? The RipDoor demo program in the RIPLINK
- portion of the DDplus package and the LDEMO demo program in
- the LOCKING portion of the DDPlus package both have working
- examples of the elog unit in action. Both also come with
- source code you can look at to see how it was done.
-
-
- TO USE THE ELOG.PAS UNIT
- ------------------------
-
- FUNCTION FILE_EXISTS - Detects if a DOS file is present in the same
- directory. Returns true if it is and false if it is
- not.
-
- PROCEDURE TERMINATE--|
- PROCEDURE TRAPEXIT---| All three of these work together to trap an exit
- PROCEDURE MYEXIT1----| and redirect it so that an error.log is created
- that's can tell you what happened and why. Makes
- debugging a lot easier. Just make sure users send
- you the error.log when they report a problem.
-
- Here is a sample of the first several lines of my main program which shows
- you how to make the ELOG unit work in YOUR program:
-
- BEGIN (*** M A I N ***)
- SaveExitProc:=Exitproc; <------ Must have this first to make it work
- ExitProc:=@MyExit1; <------ Must have this second to make it work
- GetDate(Year,Month,Day,DOW);
- INITDOORDRIVER('GOC.CTL');
- PROGNAME:='GODFATHER OF CRIME by Bob Dalton';
- etc....
