VBS error message - "Line:6, Column:1, Error:(null), Code:800401E4, Source:(null)"

I'm new to scripting and have stumbled across AutoIt which I want to personally evaluate (along with other scripting technologies). Does anyone one see any error in this code (I can't determine whether this is a VBS error or someting I开发者_JS百科 don't understand about AutoIt)?

I am using an editor called VbsEdit and I receive an error message as following: "Line:6, Column:1, Error:(null), Code:800401E4, Source:(null)"

All help appreciated. TIA

'Start AutoIt server script first

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run "h:\AutoItServer.exe" 

Set oAutoIt = GetObject("AutoIt.Application") ' the magic

WS_OVERLAPPEDWINDOW = &H00CF0000

hGui = oAutoIt.Call("GUICreate", "VBS AutoIt GUI test", -1, -1, -1, -1, WS_OVERLAPPEDWINDOW)
hButton = oAutoIt.Call("GUICtrlCreateButton", "Click", 100, 100, 100, 30)
hButton2 = oAutoIt.Call("GUICtrlCreateButton", "Click me too", 100, 300, 100, 30)

oAutoIt.Call "WinSetOnTop", "VBS AutoIt GUI test", "", 1

oAutoIt.Call "GUISetState"

    Select Case oAutoIt.Call("GUIGetMsg")
        Case -3

        Case hButton
            oAutoIt.Call "MsgBox", 262144+32+3, "Title", "Bzzz bzz bzzzz", 0, hGUI
        Case hButton2
            oAutoIt.Call "Beep", 500, 700
    End Select
    Wscript.Sleep(10)
Loop

oAutoIt.Call "GUIDelete"

If oAutoIt.Call("MsgBox", 4 + 48 + 262144, "?", "Kill server?") = 6 Then oAutoIt.Quit

The problem is that you are trying to Get the object before it is initialized completely. (at the line where the magic happens)

Try WshShell.Run "h:\AutoItServer.exe", 1, true this makes the script wait until the autoitserver is started.
