IOleClientSite::GetContainer (Compact 2013)

3/26/2014

This method requests a pointer to an object's container.

Syntax

HRESEUT GetContainer( 
  LPOLECONTAINTER FAR* ppContainer
);

Parameters

  • ppContainer
    [out] Address of IOleContainer* pointer variable that receives the interface pointer to the container object.

    If an error occurs, the implementation must set *ppContainer to NULL.

Return Value

One of the values in the following table is returned.

Value

Description

S_OK

The pointer to the container's IOleContainer interface was returned.

OLE_E_NOT_SUPPORTED

Client site is in OLE 1 container.

E_NOINTERFACE

The container does not implement the IOleContainer interface.

Remarks

If a container supports links to its embedded objects, implementing GetContainer enables link clients to enumerate the container's objects and recursively traverse a containment hierarchy.

This method is optional but recommended for all containers that expect to support links to their embedded objects.

Link clients can traverse a hierarchy of compound-document objects by recursively calling GetContainer to get a pointer to the link source's container; followed by IOleContainer to get a pointer to the container's IOleObject interface and, finally, IOleObject::GetClientSite to get the container's client site in its container.

Simple containers that do not support links to their embedded objects probably do not need to implement this method. Instead, they can return E_NOINTERFACE and set ppContainer to NULL.

To determine whether the platform supports this interface, see Determine Supported COM APIs.
