Please do not quote sigs (the '--'), it messes with some newsreaders.
Thanks.

It's copied directly[1] into the string in the vector. As long as the vector
is alive, the strings are alive. You can modify the strings in the vector:
// using the 'vec' in 'FillVector()' function
vec.at( 1 ) = "Hello";
vec.at( 1 ) += "World!";
std::string tmp(" I want to be the leader of the ");
vec.at( 0 ) = tmp;
vec.at( 0 ) += "World!";
if( vec.at( 2 ).size() < 10 ){
vec.at( 2 ) = std::string( 20, '*' );
}
.... etc.
> And do i need to call destructor for those strings?
No. When the vector gets destructed, it calls the destructors of all the
elements in it. Neat, eh? No messing with new/delete, etc., the string
handles it's data, and the vector handles it's data ( the strings).
[1] - it's a little more complex than that, but, for now, that's all you
need.

It should be "-- \n" (note the space before the newline). As such, your
sig delimiter is missing the space.

Ya know, I've never had any trouble with 'sig quoting', either on windows or
GNU/Linux mail/newsreaders. I was told not to put 'code' below my sig, as it
doesn't show in some readers ( it was some joke code).
But, WHAT newsreader(s)? If it's just one single newsreader, shouldn't the
distributor be contacted to correct it, instead of us asking posters not to
quote sigs?
OK, rant over.
Thanks for the correction.

When the sig is properly delimited, my newsreader (tin) will
automatically strip the sig before I reply.
It seems you are using Outlook Express, which will strip blank spaces at
the ends of lines, and thus corrupt your sig delimiter. I do not know
if it has the option to turn this off.

Have not found one (.. but, I didn't really look for it.).
OE does what I need, except it puts 'PGP' signed stuff as an attachment (in
some NGs), just a blank body. ;-{

Oh yeah. Why?

There are people who call OE a newsreader.
There are also people who use macros and call them templates :-)

Did I do that? I'll have to go wash my mouth out with soap.

Not me, I hate macros[1]! <G>

Note that Google messes this up sometimes. I've tried on my own
postings: the space is present in the message as it appears, but
when you hit the reply button, it gets stripped, and the sig
remains.
IMHO, this is (or should not be) a major problem. You edit the
posting you are replying to anyway, to remove the unnecessary
parts. The sig is just one more unnecessary part which needs
removing.

Yes, I've seen your posts about it in the past and I know you've
earnestly tried very hard to figure out where the problem is. It is
unfortunate that Google gets this wrong (if it is indeed caused by the
Google chain of posting).

No, but why using it then?
I switched from OE to Thunderbird some time ago and I found that they are
used quite equally. But without the bugs.

I was refering to another thread about "C++ templates" and "macro templates".

Valid usage.

Your signature delimiter is broken, too.
