How to supress command window ?

This is more of a Windows question, so before ppl start asking me to take it elsewhere, if you do know the answer, do let me know!


I am using the system(); function call from a C/C++ application for certain command line calls to the OS (WinXp / Win-Vista-32 are intended target platforms). Every time I invoke the function, a command window opens up, and displays the output. I have tried a number of things from turning echo off to writing the output of the command to a file (for example system(" dir /q > f1.txt") ), BUT, nothing stops the command window from popping up.

How do I stop it from showing up at all?

I am using DevC++ for development, so any mingW/gcc specific makefile options are most welcome.

many thanks!

    I think the solution is to use an API like CreateProcess: [link]http://msdn.microsoft.com/en-us/library/ms682425(VS.85).aspx[/link]
    Fill the start up info structure with atleast the flag STARTF_USESHOWWINDOW in dwFlags and wShowWindow to WS_HIDE. I think that should work, though I am not entirely sure.

    The way I see it... Well, it's all pretty blurry
