Hide console in windows

[Rajil Saraswat]

Hi all,

I have a written a C++ program which calls gnuplot to write out a jpg
of some data. I build a script file with appropriate gnuplot commands
and then use the system command to write out the plot, like this

system("C:\gnuplot\bin\gnuplot.exe c:\data
\gplotcmds.txt);

However this means that a dos/console window pops up everytime gnuplot
is called. Is there any way to hide the console window or use some
other means to call gnuplot. I am not interested in showing any
graphical plot on screen just want the image to be written to disk..

Cheers
Rajil

On OS/2, there is a command "start" which allows to pass several options to
a newly started window, e.g. minimized, maximized, in background, etc.
I think the same command is available on Windows as well.
Then something like system("start /background /minimized gnuplot ...") might
work as you expect.

Otherwise, use popen() to pass commands directly.
