8167 :: Execute process without waiting for the result

• Lecale (orginal) [2021-06-28T10:03:59+02:00] view original

  I'd like to execute a process, and check how long it takes for the various ui windows to appear. I was going to use something like this:

  
  let a = cpuTime()
  discard execShellCmd("runTheExeFile.bat")
  some wAuto code here
  let z = cputTime
  

  But then I realised, too late, that this won't work until the exe file is closed, or until it exits. It seems like startProcess has the same problem.

  So how else should I go about this? Should I just spawn this execShellCmd ? then the timers can work as desired after?

  startProcess does not block and should be useful for this purpose. Please share your experiment with startProcess and I'm sure we can help you further.

  Oh God, you're completely right. I renamed the file after switching to StartProcess. Unfortunately, I was executing the original executable, not the new renamed version.

  Sigh. More coffee.
