system() call in win32 c++ app

[Guest]

When using the function system() in a win32 c++ application, i notice a
seperate shell window opens and closes quickly when the app is run and this
system() call is encountered. Is there a way to suppress or prevent this
seperate shell window from opening or being seen ?

ex:
int result = system("some_other_app.exe arg1 arg2");

Look up _spawnlp (and cousins) in MSDN, such as
http://msdn2.microsoft.com/en-gb/library/t7y6z6fd(VS.80).aspx .
Basically, do something like

_spawnlp(_P_NOWAIT, "someprogram", "arg1", "arg2", ... , NULL); // NULL required as last argument.
