[COM] ObjCreateInterface v-table order?

Recommended Posts

Inververs

In help file said that:

Methods listed inside description string must be in v-table order of the interface.

how do you know this order?

For example:

i try to create IEnumUnknown interface http://msdn.microsoft.com/en-us/library/windows/desktop/ms683764(v=vs.85).aspx

It has members: Clone, Next,Reset,Skip

But as will be correct?

$dTag_IEnumUnknown = _
"Clone hresult(ptr*);" & _
"Skip hresult(ulong);" & _
"Next hresult(ulong;ptr*;ulong*);" & _
"Reset hresult();"

or

$dTag_IEnumUnknown = _
"Clone hresult(ptr*);" & _
"Next hresult(ulong;ptr*;ulong*);" & _
"Reset hresult();" & _
"Skip hresult(ulong);"

or it does not matter?

I think this will help

Unfortunately no...

as I understand it, the interface IEnumUnknowncontained - in the library ole32.dll that the program was unable to open.

but if you look at the file ObjIdl.h

....
MIDL_INTERFACE("00000100-0000-0000-C000-000000000046")
IEnumUnknown : public IUnknown
{
public:
virtual /* [local] */ HRESULT STDMETHODCALLTYPE Next(
/* [annotation][in] */
__in ULONG celt,
/* [annotation][out] */
__out_ecount_part(celt,*pceltFetched) IUnknown **rgelt,
/* [annotation][out] */
__out_opt ULONG *pceltFetched) = 0;

virtual HRESULT STDMETHODCALLTYPE Skip(
/* [in] */ ULONG celt) = 0;

virtual HRESULT STDMETHODCALLTYPE Reset( void) = 0;

virtual HRESULT STDMETHODCALLTYPE Clone(
/* [out] */ __RPC__deref_out_opt IEnumUnknown **ppenum) = 0;

};
.....

it seems to me that the correct order would be:

Next;Skip;Reset;Clone

$dtag_IEnumUnknown = "Next hresult(ulong;ptr*;ulong*);Skip hresult(ulong);Reset hresult();Clone hresult(ptr*);"

though maybe I'm wrong :rolleyes:

      I was Playing around With AutoIt this evening and wondered how hard it would be to get typeinfo like the COM Viewers do only using AutoIt
      Turns out it was pretty easy.
      A Few Notes:
      CAarray info is unfinished I didn't have any objects to test it on so I left it Limited.
      The Object must have IDispatch exposed (ITypeInfo is derivative)
      Its Just a proof of concept Run with it but don't carry scissors
      ITypeInfoCOM.au3
      ITypeInfoTest.au3
       
      Output IWebBrowserApp
       
      Output ObjCreate(MediaPlayer.MediaPlayer.1)

       Hello all"
      I have curious problem with com object implementation of Sapi 5.1.
      In some cases }Some Voice engines] the metods for retrieve the voice parameters fails with error :Member not exists:.
      But the Retrieved Voice object can speak the given text, so It exists and work.
      Example of this type of Engine can be this one: http://download.kobavision.be/KobaSpeech3/KobaSpeech 3 With Vocalizer Serena - English (Great Britain).exe (can work as demo)
      So my question is> Is there some way to workaround or solve this issue?
      What i tryed:
      1. Typical use of Sapi.spvoice object:
      $oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler
       
        $spvoice = ObjCreate("sapi.spvoice")
      for $voice in $spvoice.getvoices()
        msgbox(0, "Voice", $voice.getdescription())
      next
      Func MyErrFunc()
      $HexNumber = hex($oMyError.number, 8)
      Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
      SetError(1)
      Endfunc

      2. Implement workaround based on Nvda Screen reader sapi5 Library at https://github.com/nvaccess/nvda/blob/master/source/synthDrivers/sapi5.py
      Thys code in Pascal should work, so i tryed to reproduce it in Autoit.
      Pascal code just as example:
                   SOTokens:=SpVoice.GetVoices('','');
                   for i:=0 to SOTokens.Count-1 do
                   try
                        SOToken:=SOTokens.Item(I); s:=SOToken.GetDescription(0);
      end
      In Autoit I tryed it like this:
      $oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler
        $spvoice = ObjCreate("sapi.spvoice")
      for $i = 0 to $spvoice.getvoices.count-1
      $name = $spvoice.getvoices.item($i).getdescription
      msgbox(0,"Voice", $name)
      next
      Func MyErrFunc()
      $HexNumber = hex($oMyError.number, 8)
      Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
      SetError(1)
      Endfunc
      Both of this methods returning same Error ("Member not exists.").
      Thanks a lot for help.

      Hello,
       
      Is there a way to get all the properties and method of a COM object thru Autoit.
      I am looking in a way of display the imbricated structure of object and method.
       
      Example of COm objects are "itunes.application", "Shell.application" and so on.
      The idea is to have a code looking like
      $objtobrowse = objcreate("itunes.application") if isobj($objtobrowse) then $colItems = $objtobrowse.buildinproperty For $objItem In $colItems ConsoleWrite($objItem.<Name> & " - " & $objItem.<Value> & @CRLF) Next EndIf
