Re: Console screen from spawn_process

["Paulo Flabiano Smorigo" <pfsmorigo gmail com>]

Hi Armin,

Thanks for the fast reply!

I compile the child process with the "-mwindows" parameter but the problem is that I need to communicate with the child using stdin and stdout by the method spawn_process_with_pipes but with "-mwindows" there is no stdin and stdout...

So, there is no solution? I will have to understand the CreateProcess API ?

Even if I have a system() call in the application this blank console appears... :(

If the bug is WONTFIX means there will be no fix?

Thanks...

I guess the spawned applications needs to be built with the -mwindows
flag for this. It is also possible to change that flag after the
application has been built.

The Windows CreateProcess() API has a flag to suppress the console
window for the child, but Glib does not use it for spawning
applications.

There has been a bug report about this which has been closed as WONTFIX:
http://bugzilla.gnome.org/show_bug.cgi?id=509201

So your options are either to change the -mwindows flag of the child
process (if you have control over that), or to use the Windows
CreateProcess() API directly.
