This is the command I am using it is using other functions.

Private Type STARTUPINFO
     cb As Long
     lpReserved As String
     lpDesktop As String
     lpTitle As String
     dwX As Long
     dwY As Long
     dwXSize As Long
     dwYSize As Long
     dwXCountChars As Long
     dwYCountChars As Long
     dwFillAttribute As Long
     dwFlags As Long
     wShowWindow As Integer
     cbReserved2 As Integer
     lpReserved2 As Long
     hStdInput As Long
     hStdOutput As Long
     hStdError As Long
  End Type

  Private Type PROCESS_INFORMATION
     hProcess As Long
     hThread As Long
     dwProcessID As Long
     dwThreadID As Long
  End Type

  Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal _
     hHandle As Long, ByVal dwMilliseconds As Long) As Long

  Private Declare Function CreateProcessA Lib "kernel32" (ByVal _
     lpApplicationName As String, ByVal lpCommandLine As String, ByVal _
     lpProcessAttributes As Long, ByVal lpThreadAttributes As Long, _
     ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, _
     ByVal lpEnvironment As Long, ByVal lpCurrentDirectory As String, _
     lpStartupInfo As STARTUPINFO, lpProcessInformation As _
     PROCESS_INFORMATION) As Long

  Private Declare Function CloseHandle Lib "kernel32" _
     (ByVal hObject As Long) As Long

  Private Declare Function GetExitCodeProcess Lib "kernel32" _
     (ByVal hProcess As Long, lpExitCode As Long) As Long

  Private Const NORMAL_PRIORITY_CLASS = &H20&
  Private Const INFINITE = -1&

Public Function ExecCmd(cmdline$)
     Dim proc As PROCESS_INFORMATION
     Dim start As STARTUPINFO

     ' Initialize the STARTUPINFO structure:
     start.cb = Len(start)

     ' Start the shelled application:
     ret& = CreateProcessA(vbNullString, cmdline$, 0&, 0&, 1&, _
        NORMAL_PRIORITY_CLASS, 0&, vbNullString, start, proc)

     ' Wait for the shelled application to finish:
        ret& = WaitForSingleObject(proc.hProcess, INFINITE)
        Call GetExitCodeProcess(proc.hProcess, ret&)
        Call CloseHandle(proc.hThread)
        Call CloseHandle(proc.hProcess)
        ExecCmd = ret&
  End Function

retval = ExecCmd(App.Path & "\test.exe " & txtTestName.Text & ".cfg")

What it does it waits for this DOS command to finish before proceeding to
the next line.  What I want to to pipe the result to a text file so I can
read then later on.

Thanks
