How do I read the standard output from a child process in VB6?

Question

When creating a process in VB6 (related to this question:), I\'m using the following struct:

Private Type STARTUPINFO
      cb As Long
      lpReserved As String         


        

Answer 1

Microsoft gives here an example on how to do it.

Answer 2

See AttachConsole(ATTACH_PARENT_PROCESS)

Answer 3

Following up this other question by the OP, I post an alternative method to execute a command and get hold of stdout:

' References: "Windows Script Host Shell Object Model" '

Public Declare Sub Sleep Lib "kernel32" Alias "Sleep" ( _
  ByVal dwMilliseconds As Long)

Function ExecuteCommand(cmd As String, ExpectedResult as Long) As String
  Dim shell As New IWshRuntimeLibrary.WshShell
  Dim exec As IWshRuntimeLibrary.WshExec

  Set exec = shell.Exec(cmd)
  While exec.Status = 0
     Sleep 100
  Wend

  If exec.ExitCode = ExpectedResult Then
    ExecuteCommand = exec.StdOut.ReadAll
  Else
    ExecuteCommand = vbNullString     ' or whatever '
  End
End Function
