Mark the external executable as a so-called "gui" program. If you build it yourself, use the -mwindows option (if using GNU tools, i.e. MinGW) or /subsystem:windows option (if using MS tools). If you don't build the external executable yourself, you can still just set the header fields that indicates the "subsystem" to say that it is a "gui" executable. MS's editbin.exe for instance can do this. Note that whether a Windows executable is marked as being "gui" or "console" is just a field in its header. It has no effect on what the executable can or cannot do (like whether it can have a GUI or not). > Are there any other function I can use to solve my problem If you are specifically writing your program to run only on Windows, you can use the Win32 StartProcess() instead of g_spawn_command_line_sync() and pass the CREATE_NO_WINDOW flag in the dwCreateionFlags parameter. --tml _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
