Hi Asm,

I think most of this is subjective. OP likely meant 'i' to mean Integer
(most people use 'n' for Number). However, if 'i' means something to OP
and/or OP's team then they are welcome to use any names they want. I
typically put on some sort of prefix character just as extra insurance that
my names won't conflict with some built-in keyword (since there seem to be
more of those all the time). sz, str, wtr, wsz are all common for strings.
The 'w' is for the wide version of course. I typicaly use str for string
and cs for a CString, but there is nothing hard fast about it. I'm not sure
who gets to decide what is "good practice".

I agree with Joe that the code is easier to read if you do one declaration
per line and certainly, using variable names that make sense to the context
is a good idea.

Hi Joe,

Generally, it is good practice to avoid using commas in declaration lists.
One variable,
one line. It would be a lot better use of the names if you eliminated the
'i' (which
conveys nothing useful) or the "Window" (which conveys nothing useful) and
simply called
them "Width" and "Height", which would mean the meaningless abbreviations
of the most
important part of the name would be eliminated.

So, it seems to me that you don't like the Hungarian Notation, or you
don't consider HN useful.
I agree exspecially for simple cases like integers and the "i" or "n"
prefix.

But, why was this notation invented?
And why Windows PSDK, and even some of the MFC and ATL sources [*],
use HN? Is HN important in huge projects?
(However, it seems that in the "new" C# world, HN has been discouraged
by Microsoft coding standards.)

[*] I downloaded ATL Server shared-sources:

and they use prefixes like sz, str, wsz, etc.

Thanks in advance,
