Protected field in DOS

[Jack]

Hello,
I recall that once I wrote a little program that
could limit the number of characters the field could contain. I vaguely
recall something that looks like "getnline();" But I couldn't find it from
google and MSDN.
Any reminder?
Thanks
Jack

I have no idea what you're talking about here and what DOS has to do with

There is fgets() in C. Further, there is gets(), but that should never be
used anyway. In C++, you could also use the std::getline() function and
then truncate the result or use std::istream's readsome() member.

Cheers!

Say I had a textbox Name:_______
The user can type into box, after he has typed up to 6 characters, he would
not be allowed to continue and
the PC starts beeping... etc

The probably widest-spread library to create graphical UIs in a text screen
is called "curses". There are various flavours and variants of that
library, but you should be able to find one that suits you with that name.
