B4J Code Snippet Get Boot Up time of a Windows PC...

Well...
before some days ASK if someone knows a time/data format... explained here.

I ve create a small snippet - if someone wants to know what date/time bootup last time your Windows PC...

how to use it:

    Wait for (BootUpTime) complete (bootup As Long)
    Log(bootup)
    DateTime.DateFormat="dd/MM/yyyy"  'You can give your Date format here...
    Log(DateTime.Date(bootup))
    Log(DateTime.time(bootup))

code need to add:

Sub BootUpTime As ResumableSub
    'yyyymmddhhmmss.nnn
    Dim bootticks As Long
    Dim js As Shell
    Dim params As List
    params.Initialize

    params.Add("os")
    params.Add("get")
    params.Add("lastbootuptime")
    params.Add("/format:csv")
  
    js.Initialize("js", "wmic.exe", params)
    js.WorkingDirectory=File.DirApp
    js.Run(-1)
    Wait for (js) js_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
  
    If Success=True Then
        Log(StdOut)
        Dim nlines() As String=Regex.Split(Chr(13) & Chr(10),StdOut)
        Dim cols() As String=Regex.Split(",",nlines(2))

        DateTime.DateFormat="yyyyMMddhhmmss" '.SSS  ?? millisecond... hmm are you sure need them ?
      
        bootticks=DateTime.DateParse(cols(1).Trim)
      
    End If
  
    Return bootticks
End Sub

Small correction:

        DateTime.DateFormat="yyyyMMddHHmmss"
       
        bootticks=DateTime.DateParse(cols(1).SubString2(0, cols(1).IndexOf(".")).Trim)
