Closing the first IE instance

[Heinz Salomon]

I'm trying to close the first Internet Explorer instance.
Everything works fine, but when finally executing the quit method, the program exits with a GPF.
What am I doing wrong?

#INCLUDE "SHDOCVW.INC"
FUNCTION PBMAIN() AS LONG
  DIM objIE AS IWebBrowserApp
  DIM objShellWins AS IShellWindows
  objShellWins = NEWCOM CLSID $CLSID_SHDocVw_ShellWindows
  IF ISOBJECT(objShellWins) THEN
    PRINT STR$(objShellWins.Count) ' = 1 when tested with 1 IE instance open --> OK
    objIE = objShellWins.ITEM(0)
    IF ISOBJECT(objIE) THEN
      objIE.Quit
    END IF
  END IF
  objIE = NOTHING
  objShellWins = NOTHING
END FUNCTION

Maybe I should add that I translated the PB code from the following VB 6 code (which runs fine!):

'Reference to C:\WINDOWS\system32\shdocvw.dll set in IDE

Option Explicit

Public Sub Main()
  Dim objIE As SHDocVw.InternetExplorer
  Dim objShellWins As SHDocVw.ShellWindows
  Set objShellWins = New SHDocVw.ShellWindows
  If IsObject(objShellWins) Then
    MsgBox Str$(objShellWins.Count)
    Set objIE = objShellWins.Item(0)
    If IsObject(objIE) Then
      objIE.quit
    End If
  End If
  Set objIE = Nothing
  Set objShellWins = Nothing
End Sub

Can anybody help me? What did I do wrong?
Any hint would be greatly appreciated!!

Use Automation(ID binding) rather than Vtbl binding.

Note: I did not use the PB COM browser, therefore, the class, interface and symbol names are different from those in your original code.

#COMPILE EXE

#DIM ALL

#INCLUDE "SHELL_IDBIND.INC"

FUNCTION PBMAIN() AS LONG

  LOCAL objIE         AS ShellIWebBrowserApp
  LOCAL objShellWins  AS ShellShellWindows

  LOCAL vIndex        AS VARIANT
  LOCAL lCount        AS LONG
  LOCAL sName         AS STRING

  objShellWins = NEWCOM CLSID $CLSID_SHELLSHELLWINDOWS
  
  IF ISOBJECT(objShellWins) THEN
    OBJECT GET objShellWins.Count TO lCount
    MSGBOX "Count:" + FORMAT$(lCount) ' = 1 when tested with 1 IE instance open --> OK
    vIndex = 0
    OBJECT CALL objShellWins.Item(vIndex) TO objIE
    IF ISOBJECT(objIE) THEN   
      OBJECT GET objIE.Name TO sName
      MSGBOX "Name:" + ACODE$(sName)
      OBJECT CALL objIE.Quit
    END IF
  END IF  
  
  objIE = NOTHING
  objShellWins = NOTHING
  
END FUNCTION

Sorry guys, I was up all night and thought I was making a new thread, but replied to this one instead.
