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:
Value |
Description |
|---|---|
S_OK |
Enumerator successfully returned. |
E_NOTIMPL |
Object enumeration not supported. |
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.
