 |
|
Anyone got any code for how to print a progressbar in a console-window?
That is, - something like
"Loading: X%"
where X is continousely updated.

Standard C++ doesn't offer any way to do it. You have to refer to your system
related console programming manuals for it.

r without n sends the cursor back to the beginning of the line but not to
a new line, so you can overwrite the previous contents of the line. This is
afaik the only standards-compliant portable way to do it.

Something like
std::cout << "rLoading: " << Xvalue << '%';
The behaviour of your terminal when r is printed to it is of course
OS-specific, but it usually works the way you want it.
Don't forget to print 'std::endl' when you're done to move to the next
line.

If this doesnt work, another way I found was to use several b - so
basically:
for (int i=0; i
std::cout << "b";
std::cout << "rLoading: " << Xvalue << '%';

Yeah I think the best way to do this is with your final progress bar
dislpayed as, for example:
[0%...25%...50%...75%...100%]
And progressivly add a '.' or number to the end. Something like this:
//----------------------------
cout << "[";
for ( int x = 0; x <= 100; x++ )
{
if ( !( x % 20 ) ) // display every 20th number
cout << x << "%";
else if ( !( x % 5) ) // otherwise display a dot every 5 numbers
cout << ".";
}
cout << "]";
//----------------------------

Watch it with that. If you go too far backwards, some versions of Windows
(NT-based ones) will bluescreen spectacularly.

Some say the Wired doesn't have political borders like the real world,
but there are far too many nonsense-spouting anarchists or idiots who
think that pranks are a revolution.

Yup. The bug was fixed in Windows 2000 SP3 and Windows XP SP1. In NT4 it'll
remain a bug forever.
