IMoniker::Enum
Returns a pointer to an enumerator that can enumerate the components of the
moniker.
HRESULT Enum(
BOOL fForward,
| //Specifies direction of enumeration
| IEnumMoniker **ppenumMoniker
| //Receives the enumerator
| );
|
|
Parameters
fForward
[in] Specifies the enumeration order. TRUE enumerates the monikers from left
to right; FALSE enumerates from right to left.
ppenumMoniker
[out] Receives a pointer to an IEnumMoniker enumerator for this moniker. If an error occurs or if the moniker has no
enumerable components, the implementation sets *ppenumMoniker to NULL. If *ppenumMoniker is non-NULL, the implementation must call IUnknown::AddRef on the parameter; it is the caller's responsibility to call IUnknown::Release.
Return Values
S_OK
Indicates success. This value is returned even if the moniker does not provide
an enumerator (that is, if *ppenumMoniker equals NULL).
E_OUTOFMEMORY
Indicates insufficient memory.
E_UNEXPECTED
Indicates an unexpected error.
Comments
As examples of enumeration, the IMoniker::Enum method for a generic composite moniker creates an enumerator that returns the
individual monikers that make up the composite, and the IMoniker::Enum method for a file moniker creates an enumerator that returns monikers
representing each of the components in the pathname.
Notes to Callers
You would call this method if you want to examine the individual components
that make up a composite moniker.
Notes to Implementors
If your monikers have no discernible internal structure, your implementation
of this method can simply return S_OK and set *ppenumMoniker to NULL.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
