You could try to get the console window with 'FindWindow' and hide it
with 'ShowWindow (.., SW_HIDE)'. This way it will also disappear from the
taskbar. Problem is that you might see a little flash for the short time the
window is created until you hide it.
If you use 'CreateProcess' instead of 'system ()' you can even pass the
SW_HIDE flag in the 'wShowWindow' member of the 'STARTUPINFO' structure
passed to 'CreateProcess', which will do the same as the above solution,
just without the flash.
Other than that, I am not sure why you posted this in comp.lang.c++ as
your question does not have anything to do with the C++ Language but rather
with the OS and its API you are working with. Try posting to a more
approriate news group, if my answer does not help (which I am not too sure
of, since I have never heard about 'spawnl ()' on the OS I am using).
