IOleContainer::EnumObjects (Compact 2013)

3/26/2014

Enumerates objects in the current container.

Syntax

HRESULT EnumObjects(
  DWORD grfFlags,        //Value specifying what is to be enumerated
  IEnumUnknown **ppenum  //Address of output variable that receives the 
);                       // IEnumUnknown interface pointer

Parameters

• grfFlags
  [in] Value that specifies which objects in a container are to be enumerated, as defined in the enumeration OLECONTF.

• ppenum
  [out] Address of IEnumUnknown* pointer variable that receives the interface pointer to the enumerator object. Each time a container receives a successful call to EnumObjects, it must increase the reference count on the *ppenum pointer the method returns. It is the caller's responsibility to call IUnknown::Release when it is done with the pointer. If an error is returned, the implementation must set *ppenum to NULL.

Return Value

This method supports the standard return value E_FAIL, as well as the following:

Remarks

A container should implement EnumObjects to enable programmatic clients to find out what objects it holds. This method, however, is not called in standard linking scenarios.
