 It's in OCIdl.idl and adding these lines allow call to OnAmbientPropertyChange and set in Invoke.

type
 PtagCONTROLINFO = ^tagCONTROLINFO;

 P_RemotableHandle = ^_RemotableHandle;

 wireHACCEL = P_RemotableHandle;
 tagCONTROLINFO = packed record
     cb : LongWord;
     hAccel : wireHACCEL;
     cAccel : Word;
     dwFlags : LongWord;
 end;

type
  // IOleControl :

 IOleControl = interface(IUnknown)
   ['{B196B288-BAB4-101A-B69C-00AA00341D07}']
    // GetControlInfo :
   procedure GetControlInfo(var pCI:tagCONTROLINFO);stdcall;
    // OnMnemonic :
   procedure OnMnemonic(var pMsg:tagMSG);stdcall;
    // OnAmbientPropertyChange :
   procedure OnAmbientPropertyChange(dispID:Integer);stdcall;
    // FreezeEvents :
   procedure FreezeEvents(bFreeze:Integer);stdcall;
  end;

 I will look at it during the weekend. The main concern is the "packed".

Be careful with that (it must following the packing of the header exactly) or there is a chance it won't work on 64-bit. The same with types and/or enums that might have different sizes in 64-bit.

 Ok, thanks!

There is another one I'm using in same idl / activex, maybe look that too?!

(Browser.comserver.Document as IPersistStreamInit).Load(TStreamAdapter.Create(ms));

// IPersistStreamInit :

 IPersistStreamInit = interface(IPersist)
   ['{7FD52380-4E07-101B-AE2D-08002B2EC713}']
    // IsDirty :
   procedure IsDirty;safecall;
    // Load :
   procedure Load(pstm:IStream);safecall;
    // Save :
   procedure Save(pstm:IStream;fClearDirty:Integer);safecall;
    // GetSizeMax :
   procedure GetSizeMax(out pCbSize:_ULARGE_INTEGER);safecall;
    // InitNew :
   procedure InitNew;safecall;

  end;

BTW, why does "Import type library" create only procedures, bug? These are really functions.

 See 22109 for import type library and procedures question.

 It doesn't compile :-)

urlmon.pas(375,29) Error: Data types which require initialization/finalization can't be used in variant records

which is the TAGBINDPTR definition

 Well, I didn't try to compile all of it. Just copied parts needed (those in notes 1 and 3)

 Attached patch for IPersistStreamInit.

I changed safecalls to HResult;StdCall; based on:

http://msdn.microsoft.com/en-us/library/windows/desktop/ms682273(v=vs.85).aspx [^]

Is there something wrong with this, works here.
