I search answers on this site , but they do not have complete info
I have a file c: ....test.xlsm it has a subroutine test () 
sub test () 
msgbox "hello stackoverflow"
end sub
I want to write a vbscript that would
1) open c: ....test.xlsm 
2) run test () subroutine 
3) close c: ....test.xlsm 
How can I do this ?
