SAP connection

[trax100]

Hi,
does anybody tryied connect to SAP Gui and its ScriptingEngine???
In VBScript you have to run this code

    If Not IsObject(application) Then
       Set SapGuiAuto  = GetObject("SAPGUI")
       Set application = SapGuiAuto.GetScriptingEngine
    End If
    If Not IsObject(connection) Then
       Set connection = application.Children(0)
    End If
    If Not IsObject(session) Then
       Set session    = connection.Children(0)
    End If
    If IsObject(WScript) Then
       WScript.ConnectObject session,     "on"
       WScript.ConnectObject application, "on"
    End If

    session.findById("wnd[0]").maximize

---

But in LuaCOM it failed at connection = application:Children(0)
see the Lua code

function help(t)
    for k,v in pairs(t) do print(k,v) end
end

require("luacom")

-- luacom.config.abort_on_API_error = true
-- luacom.config.abort_on_error = false

print("SapGuiAuto")
-- local Wrp = luacom.CreateObject ("SapROTWr.SapROTWrapper")
-- local SapGuiAuto = Wrp:GetROTEntry ("SAPGUI")
local SapGuiAuto  = luacom.GetObject("SAPGUI")
if not SapGuiAuto then error("SapGuiAuto missing") else help(SapGuiAuto) end
print()

print("application")
local application = SapGuiAuto:GetScriptingEngine()
if not application then error("application failed") else help(application) end
print()

print("connection")
local connection = application:Children(0)
if not connection then error("connection failed") else help(connection) end
print()

print("session")
local session = connection:Children(0)
if not session then error("session failed") else help(session)end
print()

   -- WScript.ConnectObject session,     "on"
   -- WScript.ConnectObject application, "on"

-- session.findById("wnd[0]").maximize

print("working") 

Program output:
