I think you can use "cmd /c start /b" or something along those lines to hide the cmd window.

end function 

Example:

include std/utils.e 
include internet.e 
 
sequence result = InternetGetConnectedState() 
sequence status = iff( result[1], "Online", "Offline" ) 
 
printf( 1, "status = %s (flags = #%02x)\n", {status,result[2]} ) 

Output:

status = Online (flags = #12)
