DWORD dwWhichMoniker,	//Value specifying moniker being set
IMoniker *pmk	//Pointer to moniker
);

Parameters
dwWhichMoniker
[in] Specifies which moniker is passed in pmk. Values are from the enumeration OLEWHICHMK.

pmk
[in] Points to where to return the moniker.

Return Values
S_OK

Moniker successfully set.

E_FAIL

No client site for object.

Comments
A container that supports links to embedded objects must be able to inform an embedded object when its moniker has changed. Otherwise, subsequent attempts by link clients to bind to the object will fail.The IOleObject::SetMoniker method provides one way for a container to communicate this information.

The container can pass either its own moniker, an object's moniker relative to the container, or an object's full moniker. In practice, if a container passes anything other than an object's full moniker, each object calls the container back to request assignment of the full moniker, which the object requires to register itself in the running object table.

The moniker of an object relative to its container is stored by the object handler as part of the object's persistent state. The moniker of the object's container, however, must not be persistently stored inside the object because the container can be renamed at any time.

Notes to Callers
A container calls IOleObject::SetMoniker when the container has been renamed, and the container's embedded objects currently or can potentially serve as link sources. Containers call SetMoniker mainly in the context of linking because an embedded object is already is aware of its moniker. Even in the context of linking, calling this method is optional because objects can call IOleClientSite::GetMoniker to force assignment of a new moniker.

Note to Implementors
Upon receiving a call to SetMoniker, an object should register its full moniker in the running object table and send OnRename notification to all advise sinks that exist for the object.

    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.
