I have a simple question I'd like help on. :] How, if at all, would one go about suppressing the console window that flashes up when you make at system() call in your C++ program? I'm using Dev-C++ with GTK-- with all the 'GUI' options ticked. There is nothing functionally wrong with the program save this flashing console window. The calls in question are to console apps that reside on the target OS, the best example I could think of would be passing some info through grep. (Why re-invent the wheel eh?) I'd like to keep the solution as lightweight as possible, as I do plan to make the program support both Linux and Windows, and it must be compatible with Windows 2K. Although I am currently only compiling under Windows, so I'll leave the Linux questions for later. :] (So sadly http://msdn.microsoft.com/msdnmag/issues/04/02/CQA/ wouldn't work it seems.)

Unfortunately, the process spawning design is different on these OSes; hence will most probably have to #ifdef some parts of your implementation. It is worth to check first how Cygwin handles the issue but I doubt it has a full-fledged fork()..

Hope this helps -Pavel Thanks for your reply. =] It's taken some fiddling, but it's working (almost) perfect. A bit more playing around and it should be done.
