vbscript .run show output

Question

I can run successfully test.vbs with syntax:

Dim WshShell
Set WshShell = CreateObject("WScript.Shell")

sEXE = """\\uncpath\file.exe"""
with CreateObject("WScript.Shell")
  .Run sEXE & " ", 1, true ' Wait for finish or False to not wait
end with

however I want to store the output to \\\uncpath\%computername%.txt

This doesn't work:

sEXE = """\\uncpath\file.exe>>\\uncpath\%computername%.txt"""
with CreateObject("WScript.Shell")
  .Run sEXE & " ", 1, true ' Wait for finish or False to not wait
end with

error with line: with CreateObject("WScript.Shell")

This doesn't work either.

sEXE = """\\uncpath\file.exe"""
with CreateObject("WScript.Shell")
  .Run sEXE & " >>\\uncpath\%computername%.txt", 1, true ' Wait for finish or False to not wait
end with

any help?

Answer 1

The .Run() method doesn't have the ability to read the standard output from a task you use .Exec() for that, but you need a few changes to simulate the blocking that .Run() does for you automatically.

Dim WshShell, sEXE, cmd, result
Set WshShell = CreateObject("WScript.Shell")

sEXE = """\\uncpath\file.exe"""
With CreateObject("WScript.Shell")
  Set cmd = .Exec(sEXE)
  'Block until complete.
  Do While cmd.Status <> 1
     WScript.Sleep 100
  Loop
  'Get output
  result = cmd.StdOut.Readall()
  'Check the output
  WScript.Echo result
  Set cmd = Nothing
End With

The other approach is to prefix the sEXE variable so you are using cmd /c (as the >> command is part of that).

This should work

sEXE = "cmd /c ""\\uncpath\file.exe >> \\uncpath\%computername%.txt"""
With CreateObject("WScript.Shell")
  .Run sEXE & " ", 1, true ' Wait for finish or False to not wait
End With
