about Rating of C++:

 Personally, I think this way is a kludge which should never have been legal. 
The same effect is much cleaner obtained by declaring the constructor in the

Subj: File accessing...

Hello Kevin,
Nice to seeya again, if you wan't to access files in Basic here's some stuff:
let's say you wan't to open a file called 'name.txt' this is how:
OPEN "name.txt" FOR INPUT AS #1
INPUT #1, FIRSTLINE$
CLOSE #1
PRINT FIRSTLINE$
This is how to do it in MS Qbasic I hope you don't wan't it in Visual Basic
since I don't program in it.
Err how?
well this program opens a file called name.txt for INPUT this means the file
will be opened for reading data from it, if the file was opened for OUTPUT it
means the file opened for data input. The file must exist before it can be
opened.
There are also other ATT's for opening files like RANDON, etc.. should be in
online help or your Qbasic Programmers reference.
I hope this works for you, I had to do the code in a hurry but it should 
ork,
email me if you have any problems.
Seeya, Quin (short fot Quintin)

Subj: Scroll Lock

Hello All!
Thanks to the person (or people, if the messages haven't reached me yet <g>)
who replied to my message on getting the scroll lock status.
Just one question, how would I change the status?
I'm trying to expand my program that does the "in" and "out", to maybe a util
for sysops to remotely toggle it.

There ya go!   Mind you, I've just read your message again... and noticed the
VisualC++ part, which means you don't want to know any of my rabid ramblings. 
I
used VC++ 1.0 at work, it's an older version, but perfectly useable.  You
probably want to take your sentence from a Textbox or something like that do
you?  If you can cut'n'paste you could try the above provided there's a 
console
or something similar.  Hmm.  Well, just tryin' to help.  :)

Subj: File handling in BASIC

Y'ello Kevin!
What do you want to do?  If it's just manipulating text files, that's a 
doddle.
If you want to use a structured, random-access file, again, BASIC allows you 
to
do this quite easily, although I would be the first to admit the syntax is
cumbersome.
Say, for example you wanted to do something like convert one file to all 
pper
case, and save it to another file.  (Forgive twee and contrived example)
OPEN "file1" FOR INPUT AS 1
OPEN "file2" FOR OUTPUT AS 2
WHILE NOT EOF(1)
    LINE INPUT #1, l$
    PRINT #2, UCASE$(l$)
WEND
CLOSE
END
I think BASIC is a fantastic, versatile wee language and because things can 
e
rustled up really quickly, you can a working solution in nae time at a'.  I 
use
MS-QuickBASIC 4 all the time.
Stream handling in C++ is Ok too, though...  I could give you an example
similar to the one above if you like.  If I'm being condescending and saying
stuff that's insulting or far less complex than what you were trying to do, I
really am sorry.  I get accused of over-simplifying things.  I just like to 
try
to explain myself correctly.  :)
Seeya!

I thought decompiling was impossible with C or C++ because of the complexity 
of variables and the like.  I read that in Snippits.

For example: make use of the streams-capabilities of C++. (I'm using BC++  
4.52, I don't know, if it works with this syntax in visual c++):
---------cut off-------------------------------------
...
struct
{
   char* FromName[36];
   char* ToName[36];
   etc...
} msg;
fstream f;
f.open("file.hds", ios::in | ios::binary);
f.seekg( (sizeof(msg) * n - 1));
f.read((unsigned char*)&msg, sizeof(msg));
f.close();
...
---------------cut off-----------------------------------
with n is the number of the message between 1 and max.
I think, that the message-text hasn't a fixed size to store it in a  
structure. If so, you have to open the file like above and to read each  
message like in a sequentiel file until you reach your searched record...
If you've more questions: ask me! :-)
Bye, yours

add "-pg" when compiling ... run the program ... start gprof !!!
