Returns a pointer to the object identified by the specified name.
| LPOLESTR pszItem,
||//Name of the object requested
| DWORD dwSpeedNeeded,

| IBindCtx *pbc,

| REFIID riid,
||//IID of interface pointer desired
| void **ppvObject
||//Receives interface pointer
[in] Points to a zero-terminated string containing the container's name for
the requested object. For Win32 applications, the LPOLESTR
type indicates a wide character string (two bytes per character); otherwise,
the string has one byte per character.
[in] Indicates approximately how long the caller will wait to get the object.
The legal values for dwSpeedNeeded
are taken from the enumeration BINDSPEED
. For information on the BINDSPEED
enumeration, see the "Data Structures" section.
[in] Points to the bind context to be used in this binding operation. The bind
context caches objects bound during the binding process, contains parameters
that apply to all operations using the bind context, and provides the means by
which the binding implementation should retrieve information about its
environment. For more information, see IBindCtx
[in] Specifies the type of interface pointer requested.
[out] Receives a pointer to the object named by pszItem
. If an error occurs, the implementation sets *ppvObject
to NULL. If *ppvObject
is non-NULL, the implementation must call IUnknown::AddRef
on the parameter; it is the caller's responsibility to call IUnknown::Release
The specified object was successfully returned.
The binding operation could not be completed within the time limit specified
by the bind context's BIND_OPTS
structure, or with the speed indicated by the dwSpeedNeeded
The parameter pszItem
does not identify a object in this container.
The requested interface was not available.
The item moniker implementation of IMoniker::BindToObject
calls this method, passing the name stored within the item moniker as the pszItem
Notes to Implementors
Your implementation of IOleItemContainer::GetObject
should first determine whether pszItem
is a valid name for one of the container's objects. If not, you should return
names an embedded or linked object, your implementation must check the value
of the dwSpeedNeeded
parameter. If the value is BINDSPEED_IMMEDIATE and the object is not yet
loaded, you should return MK_E_EXCEEDEDDEADLINE. If the object is loaded, your
implementation should determine whether the object is running (for example, by
calling the OleIsRunning
API function). If it is not running and the dwSpeedNeeded
value is BINDSPEED_MODERATE, your implementation should return
MK_E_EXCEEDEDDEADLINE. If the object is not running and dwSpeedNeeded
is BINDSPEED_INDEFINITE, your implementation should call the OleRun
API function to put the object in the running state. Then it can query the
object for the requested interface. Note that it is important the object be
running before you query for the interface.
names a pseudo-object, your implementation can ignore the dwSpeedNeeded
parameter because a pseudo-object is running whenever its container is
running. In this case, your implementation can simply query for the requested
If you want more specific information about the time limit than is given by dwSpeedNeeded
, you can call IBindCtx::GetBindOptions
on the pbc
parameter to get the actual deadline parameter.
