VBScript - Capturing output from stdout -


i know has been answered 1 in question, not understand how done.

i trying output of command line program (aria2 downloader) hta script can parsed , download percentage, file size etc can obtained , updated div dynamically.

here code have adjusted , have been trying use locks interface until command line has finished , displays output, instead of displaying , when comes through.

const wshrunning = 0 const wshfinished = 1 const wshfailed = 2 strcommand = "ping.exe 127.0.0.1"  set wshshell = createobject("wscript.shell") set wshshellexec = wshshell.exec(strcommand)  while wshshellexec.status = wshrunning     window.settimeout "", 100 loop  select case wshshellexec.status     case wshfinished         stroutput = wshshellexec.stdout.readall()     case wshfailed         stroutput = wshshellexec.stderr.readall() end select  set objitem = document.getelementbyid("status")     objitem.innerhtml = "" & stroutput & ""

how modify doesn't lock user interface , grabs output , displays in "status" div comes through?

the problem code not end, returning control browser. don't leave loop until program ends , perceived status interface hangs until subprocess ends.

you need set callback browser periodically call code update status , leave.

<html> <head>     <title>pingtest</title>     <hta:application         applicationname="pingtest"         id="pingtest"         version="1.0"     /> </head>  <script language="vbscript">     const wshrunning = 0     const wshfinished = 1     const wshfailed = 2      dim wshshellexec, interval      sub window_onload         launchprocess     end sub      sub launchprocess         set wshshellexec = createobject("wscript.shell").exec("ping -n 10 127.0.0.1")         interval = window.setinterval(getref("updatestatus"),500)     end sub          sub updatestatus     dim status          set status = document.getelementbyid("status")         select case wshshellexec.status             case wshrunning                 status.innerhtml = status.innerhtml & "<br>" & wshshellexec.stdout.readline()             case wshfinished, wshfailed                 status.innerhtml = status.innerhtml & "<br>" & replace(wshshellexec.stdout.readall(),vbcrlf,"<br>")                 window.clearinterval(interval)                 interval = empty         end select     end sub </script>  <body>     <div id="status"></div> </body> </html>

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
