RE: Multiple entry points (MS Windows)

On Windows there are multiple ways to run a program and suppress a Window.

I usually run the program from a shortcut that is set to "Minimize" by default.

That way it just shows up as an icon on the task bar instead of a console Window.

This site walks through multiple ways to run any Windows app with no Window.

If you want to do it using the Perl program itself then you can use the Win32::GUI package.

In your code test for the operating system and on Windows have a command line option to hide the Window.

This program will hide its own console on Windows. The console will flash briefly on the screen and then hide. I usually start an app like this using a shortcut that starts minimized. That way there is an icon that briefly shows up on the task bar and disappears while the program continues to run.

use warnings;

use strict;

use Win32::GUI;

my $console = Win32::GUI::GetPerlWindow();

Win32::GUI::Hide($console);

system ('timeout 10');
