IOleObject::GetMoniker

This method retrieves an embedded object’s moniker, which the caller can use to link to the object.

At a Glance

Syntax

HRESULT GetMoinker( DWORD dwAsign, DWORD dwWhichMoinker,
IMoniker ** ppmk);

Parameters

dwAssign

[in] Determines how the moniker is assigned to the object. Depending on the value of dwAssign, IOleObject::GetMoniker does one of the following:

• Obtains a moniker only if one has already been assigned.
  
  
• Forces assignment of a moniker, if necessary, in order to satisfy the call.
  
  
• Obtains a temporary moniker.

Values for dwAssign are specified in the enumeration OLEGETMONIKER.

dwWhichMoniker

[in] Specifies the form of the moniker being requested. Valid values are taken from the enumeration OLEWHICHMK.

ppmk

[out] Address of IMoniker* pointer variable that receives the interface pointer to the object’s moniker. If an error occurs, *ppmk must be set to NULL. Each time an object receives a call to GetMoniker, it must increase the reference count on *ppmk. It is the caller’s responsibility to call Release when it is done with *ppmk.

Remarks

You cannot pass OLEGETMONIKER_UNASSIGN when calling IOleObject::GetMoniker. This value is valid only when calling IOleClientSite::GetMoniker.

The IOleObject::GetMoniker method returns an object’s moniker. Like IOleObject::SetMoniker, this method is important only in the context of managing links to embedded objects and even in that case is optional. A potential link client that requires an object’s moniker to bind to the object can call this method to obtain that moniker. The default implementation of IOleObject::GetMoniker calls the IOleClientSite::GetMoniker, returning E_UNEXPECTED if the object is not running or does not have a valid pointer to a client site.
