Developer Notes:  (Now in chronological order, Newer items near top...)

29/8  - Decided to freeze the code here and open MeSsoN up to the public. This 
		code has been labelled 1.0.2.

28/8  - There was a major crashing bug which occured whenever I closed the 
		WndContacts window... I've therefore changed the code in the cancel 
		close to quit whenever the window is closed.. I think that the 
		problems were around becuase nearly everything in MeSsoN carries a 
		reference to wndContacts, therefore as Matt Neuberg (I think) in 
		Learning REALbasic said, for some reason, REALbasic can't deal with all 
		these abandoned references and handle them properly...  Anyway, without 
		the main window open, there is little point to the program, so I 
		don't think that this is a major cludge... (Someone is of course 
		welcome to fix it properly...)

28/8  - You can now chage your friendlyname! (Unlisted command)
		Therefore I had to add support for Friendlynames which contain a space 
		(I believe they exist, though none of my friends have one...)  
		Therefore, I think I've managed to make every reference to friendlyname 
		pass through a function called (oddly enough), percent20... IT seems to 
		work...

28/8  - Added a MSNP2 errata file. This describes parts of the MSN protocol 
		that aren't mentioned in the RFC.

28/8  - Added support for finding out when you have new Hotmail e-mail.

28/8  - There is now support for Deleting users from the FL as well (Command 
		-Delete) or use themenu item.  You can also delete entries in the AL 
		and BL by simply pressing the delete key.  Fixed a fairly major bug in 
		the Preference windows.  I'm now going through the routines which talk 
		to the server, to make sure that they check that they are connected 
		before they try to talk...  (Problems with talking halfway through 
		authentication has been plaguing me slightly...)  Getting closer and 
		closer to the initial release.  
		
		Version number is currently 1.0.2 (I've been releasing it for testing 
		on a limited basis.. i.e. to my brother)

27/8  - After staying up way too late going out for most of the weekend, I 
		wasn't in the mood to tackle those idiotic file routines.. Anyway, I 
		printed out the 4 or so pages of the write routine, and went through it 
		with one of those traditional writing implements.. The result is what I 
		think is now a finally debugged version of the file writing routine... 
		(Thank God..)

		Today I've also added support for adding new users to your FL...  
		Presumably MSN requires you to add them to your Allowed list as well ? 

21/8  - I have not been idle, but implementing this software's file write/read 
		routines... I have come up against a major BUG?!  The main MeSsoN file 
		begins with a Pascal string, and I perform this line of code 
		file.position=file.readbyte.. I expected the readbyte to move the 
		pointer on by one, and then also the length of the string.. It doesn't 
		however, and only moves the pointer on the length of the string without 
		the byte taken into account.. This explains many of my problems, and I 
		suppose that it isn't really that stupid (but irritating..) Hopefully I 	
		should have the first version out soon...  This does of course mean 
		re-writing much of the file routine.. (I have multiple readbytes in one 
		position thing you see...)  
		
		Phew... I just did some investigation in a scrap project.. It looks 
		like, if you do soemthing like this 
		b.position=b.readbyte+b.readbyte+b.readbyte the program will actually 
		read three individual bytes (in order, and set the position to the 		
		total of the 3 bytes), excluding the length of the bytes themselves.. I 
		love REALsoftware.. That means I don't have to rewrite my code, I just 
		add one for every byte and 2 for every short...  woohey!!!

		Also, with reading bytes for position, doing something like 
		b.readbyte+1+b.readbyte, will read the two concurrent bytes and then 
		add 1, not read the first byte, skip a byte, and then read another 
		byte.. That's OK though, just letting anyone else who is interested 
		know....

15/8  - Fixed more bugs than I can count.. With use, they appear to be getting 
		slowly uncovered.. (yes, I am now using this as my full time client 
		now..)

15/8  - Added Preference support.. This means that the position of the contact 
		list is now saved on close :)

14/8  - With a few code changes, the chat now works!  Font support etc. isn't 
		there yet, but should be soon if I can be bothered.. At least it 
		works...

14/8  - Moved the dataAvailable into a separate method.. (I wanted to be able
      	to call it from the outside...)
14/8  - Problems associated with talking with other users... What I've done is 	
		arguably created a kludge...  I have moved the Dataavailable event 	
		handler to a dataavail method.  Created a boolean property to flag when 	
		a specified amount of data is expected (i.e. in the case of a MSG 
		command).  dataavail checks this boolean.. an if statememnt has been 
		added to the while loop to check for the message flag being raised 
		(which I hope should fix the problems I was having.. )  (there is noone 
		online right now for me to test it with.. :()
		While this boolean is true, MSG is handed to the parsing routine so 
		that the MSG handler can check for more data.. If there is enough data, 
		then readmessage is called and the boolean is unflagged...  (that is a 
		long work around.. suggestions for a more elegant solution will not go 	
		unnoticed..)


Any help would be greatly appreciated. (The interface needs some work in the way of icons etc.  (I can't stress this enough...))


*There are a few stability issues relating to REALbasic's handling of sockets in the IDE.. for some reason I think that the buffers aren't flushed after use so if the project is run twice, a crash can occur.. I don't believe that there are any similar problems with the compiled version...
	13/8 I think that this is now fixed...

* There were problems reading data, as I got confused and thought that CRLF was
chr(10)+chr(13) rather than the other way round!!!  This has been an embarassing mistake, but miraculiously most of the code works!!
	Woops...

* Most data is stored in a fasion with fields separated by chr(10), and complete sets of data, (fields), delimited by chr(10)+chr(13), this arrose due to my confusement between CR and LF... Sorry.. can be bothered to change every reference right now when everything appears to be working..

* For the chat window, I've decided to issolate the talking and listening code into two elements...  Therefore to talk, the chatwindow is actually going to write straight to the socket, I know this probably violates some people's view of OOP, but MSNs chatting appears to be complicated (involving lengths, fonts, etc....), I'm therefore encapsulating all chat stuff into the wndChat's code.

* What the F**k is REALbasic doing?!  Currently my situation is that I've got my main array of sockets in wndContacts, and my replicate method appending to it.. No problems right?  Wrong!!  the bloody thing is giving me nil Object Exception errors at random points hilighting random pieces of code! At the moment, it's even hi-lighting a comment.. REAL programmers, what the hell have you been doing with the inards of this things code?!
	Anwyay, enough flaming for tonight, I must fix the problem!
	
	13/8 this has been fixed, I am now first appending the socket (in the 
	     replicate handler), and then setting all of it's properties.. for some 
		 reason this works.. damn you REAL...
	
* Some of the IDE stability problems appear to now be gone!  I noticed that I wasn't setting the wndContacts property "lord" in sckMain to point to the wndContacts windows.. Now that that is done, things appear to be more stable. Unfortunately, I'm still unsure on quite what is going on with those duplicating sockets....  grrrr...



And that's it.. There's probably a lot I haven't explained (and I know much of the source is improperly commented... This should improve in time, but using Linus's philosophy, my plan is first to get it working then add features and style...  (Updates will be added in chronological order soon (I wrote this file all at once you see :))

P.S.  Happy Hacking  :-)
