So does that mean you want the program or no? :)

Why yes Al,

He he...
When i dont plan on releasing a program i typically leave lots
of old notes in with the files.
Also, i wanted to do a Debug run (one of my other programs) to
have all the included files printed out so i can zip them up
with the main file.
BTW i dont think i have your email around, what is it again?

Hello again Al,
I don't know if there is any great rush on this. I'm writing a windows
compare program in two parts. 1) compare folder and 2) compare files. I'm doing
this with combo boxes so I don't have keep entering file and folder names. The
folder part I got ok, it gives me a list of all the files that are the same and
and list of all the files that are different.
Now when it comes to files it is much more complicated. I found a program in
the Archives that does this diff.zip by R. M. Forno. My main goal is to compare
different versions of Arwen to to see haw to place color tabs.
Forno's diff works fine on small test programs but when I tried to compare 2
versions of Arwen it took too long. So I left it running all night.
He has 4 versions and four options to go with each ver. (I haven't tried them
all. I only tried one.)
Next day it was still running. Maybe what I am tring to do is an imposible
task.
Regardless, I would like to see your code. You can see it to the easily
hacked email address that shows up in every post. doncole at pacbell.net.
[OT]Speaking of pacbell(Park) now AT&T(Park) they're having the All Star Game
there this week and I'm already sick of the news coverage.

8. Re: Don: Compare Directories and Files
Hi Don,
Maybe this method will be faster:
1. Sort both listings, seperately
2. Have a routine that steps through both lists, comparing.
a) Grab one record each from list1 and list2
b) if two records are equal, go back to (a).
c) If the record in list1 is greater than the record in list2, then
the record in list2 is missing from list1; assume that the list1
record is a new one. Write it, get another record from list2, goto (a)
d) Same as (c) but transpose the 2 lists
I have an example of this in the archive, it speeds through megabytes of data
in less than a second, if the data is in cache. See "difflist" by me.
Cheers
Alan
9. Re: Don: Compare Directories and Files
Oops - my algo had an error in point (c). It should read:
c) If the record in list1 is greater than the record in list2, then
the record in list2 is missing from list1; assume that the list1
record is a new one. Write it, get another record from list2, goto (*b*)

Hi again Don,
Comparing files really isnt hard at all.
Since the bytes can be different however, all the bytes must be
compared. This is especially important when comparing files
on the hard drive to files on a recorded CD or DVD disk because
those files could be corrupt by only 1 single byte and that
could screw up the system reading of the entire file. I've
actually had this happen a few times, so that's why this program
came about.
The program makes a list of all the files to be checked, then
goes through them one by one checking each and every byte.
If there is even one byte that is not the same or if one
file has even one single byte less than the other an error
gets written to the Report.txt file that says what the file
name is and it's location.
Just a few weeks ago while i was trying out some new brand CD's
(that i never used before) i had some 6000 files record just
perfectly on CD, while 3 had corrupt bytes. I found that
out later, but what happened was i went to copy the files on CD
back to the hard drive and i got an error when the system copy
got to one file that would not copy and took a real long time
to provide the error message "could not read from disk" or
something like that. At that point, the system copy stopped
altogether so any files that were not copied up to that point
were simply not copied either, even though those files were ok.
I eventually got the stuff copied, but after it finally went
through all the files there were 3 files that were corrupt.
Luckily i wasnt depending on that data for anything important
as i still had the hard drive copies.
Now, i verify every file that gets recorded either using this
program or Nero verify. (Oh yeah another reason for this program
is that the old Nero 'verify' i had would cause an exception
if there were too many files in one directory. Ahead made an update
now though, but it's no big deal at this point and i pretty much
like using my own programs better anyway).
The code i will send you has been checked to make sure all the
includes get included in the zip. It's basically DOS oriented
though, but it's still easy to use. I was thinking of doing
a windows interface too btw. That would be neat. For now,
the directory and two drive letters get inserted into lines
in the Eu program source file. Since the program can look
down into sub dirs it only takes a few seconds to use anyway.
Take care,
Al

Try WinDiff from the Archive, or better GNU diffutils for Win32 (Google for that
to find the sourceforge page, I don't remember it OTOH).

Hi Don,
Can you give me a link where I can download 2 sample filelistings
that you wish to compare? Or even mail them to me, zipped.
I'll run my program against it and give you the results plus timings.
You've got nothing to lose.

Hello Alan,
http://palacebuilders.pwp.blueyonder.co.uk/edita.htm#download
I'm only interested in Arwen at this time. Conmpare it with any old Arwens you
may have. If you don't have any, download 'Arwen win32 library' by Mike.
That's in the Archives.
Thanks for your help.

Hello again Alan,
I forgot to mention you have two difflist files in the Archives, which one

Don, what is the problem? It /is/ a tough compare, and while I am sure a windows
port of the unix command-line diff runs much quicker, even on this crappy box,
Edita solves this in 17 mins, at 2006 differences [see PPPS] and a complexity of
~5.8 million (meaning that in those 17 mins it logged 5.8 million decision points
before finding the optimal answer) but it got there.
Is there something wrong with the Edita file compare output?
Is there something wrong with coloured tabs in Edita?
If you failed to understand the source mods I posted what makes you think you
will understand a source diff anyway? 
Is there something in the new Arwen you need in the one I ship with Edita?
Confused,
Pete
PS to Alan Oxley: I would be interested in your results but I have to warn you I
spent much time investigating source comparision and would be (pleasantly)
surprised to see my code beat, on the same kit that is.
PPS to Al Getz: I fell off my chair laughing at your "Comparing files really
isnt hard at all." - obviously "are these files binary identical?" is what you
probably meant, but "shortest edit difference" has kept some very bright
acedemics awake at night long time now and still will for some time yet.
PPPS If you can prove it is even one less than 2006, please let me know.
PPPPS I just want to say that 17 mins is directly related to the 2006
differences; were there only 100 it should get it done in under a second.

Apparently you have uploaded a new version of Edita. (The old one didn't have
coloed tabs.)

Sorry Pete,
But I can't spend anymore time on this post as I have to download the new
version of Edita and check out those colored tabs.

17. Re: Don: Compare Directories and Files
OK Don,
the July 13th 2007, difflist v3.0 is the later one.
I'm going to change that program a bit to better fit your needs.
(Strip unneeded features and change some titles etc)
I assume you would like something that says:
Line 64281 added: " source code line here"
Line 436 removed: " other source line here"
etc, etc?
Plus totals of lines added and removed.
Yes?
Assuming yes, will do today and send you the results.
BTW, my algorithm is not really affected by the number of differences.

To Alan,
I DID NOT receive any files from you, at lease not by email.
To Al,
I DID recieve your file in my email and will be looking into it.
To Pete,
I downloaded the lastest version of Edita and the Colored Tabs seem to work
fine. I like your idea of making a ListView. I was tring to hard code to colors
into my source. Thank you Pete.
To everybody,
Although Pete has solved my problem with color tabs and Edita, I still want to
continue my windows compare project.
Thanks everyone for your help.

Nothing has bounced back. Please mail me at either of these, and I'll use your
