Default handler for OLE interface

[olivier evalet]

Hello,
I'm looking to create a default handler for these interfaces:
- IStorage
- IOleInPlaceFrame not
- IOleClientSite
- IOleInPlaceSite not
- IOleContainer not

The reason of this... I just want to display an OLE component without
binding with the native atl.dll. I have found a pure win32 example to
implement this.

So, If I want to use a "null" IStorage default handler, does there
already exist or I must implement it?

As I can see in the source code, OLE is really hard for my head.

Regards,
Olivier

Hi,

I think we already have an implementation for the OLE provided IStorage
implementation. The others I'm not sure about.

I don't understand, sorry. ATL is a set of C++ convenience wrappers around
COM and is redistributable. All the infrastructure for displaying embedded
OLE/AcitveX controls is already in Wine... do you think we're missing
something?

Does OLE provide such a beast? I've never encountered it if so, only the
standard compound document IStorage impl. If Windows provides an IStorage
that goes to /dev/null we should implement that too.

Yes, it can be confusing.

Humm, I don't know, I have a dll "atl.dll" with this fonction:
void AtlAxGetControl( HWND h, IUnknown** pp);

With this fonction it is really easy to embed controls in a windows.
Actually I try to have the same behavior without using the native dll. I
have found an example which describe howto embed IE in a HWND. This
example implement the following code:

// OleCreate
// site is an implementation of IOleClientSite, IOleInPlaceSite
// storage is an implementation of IStorage
// mpWebObject is an implementation of IOleContainer

OleCreate(CLSID_WebBrowser,IID_IOleObject,OLERENDER_DRAW,0,&site,&storage,(void**)&mpWebObject);
mpWebObject->SetHostNames(L"Web Host",L"Web View");
RECT rect;
GetClientRect(hwnd,&rect);

// DoVerb embed the component in the hwnd_parent
mpWebObject->DoVerb(OLEIVERB_SHOW,NULL,&site,-1,hwnd_parent,&rect);

I don't know how to start correctly my code to implement this in wine?
There are a lot of interface just for displaying an ActiveX. I think
that I must implement all interfaces but I don't know how to begin...
For example, the object "site" is an implementation of IOleClientSite
and IOleInPlaceSite, I have read the wine documentation and I don't see
how to implement multiple OLE interfaces in C.

Merci,
