This method returns a value that indicates the status of an object at creation and loading.
Syntax
HRESULT GetMiscStatus(
DWORD dwAspect,
DWORD* pdwStatus
);
Parameters
dwAspect
[in] Specifies the aspect of an object about which status information is being requested.The value is obtained from the enumeration DVASPECT.

[out] Pointer to where the status information is returned; cannot be NULL.
Return Value
One of the values in the following table is returned.
Value |
Description |
|---|---|
S_OK |
Status information returned successfully. |
OLE_S_USEREG |
Delegate the retrieval of miscellaneous status information to the default handler's implementation of this method. |
CO_E_CLASSNOTREG |
There is no CLSID registered for the object. |
CO_E_READREGDB |
Error accessing the registry. |
Remarks
A container typically calls GetMiscStatus when it creates or loads an object in order to determine how to display the object and what types of behaviors it supports.
Objects store status information in the registry.
If the object is not running, the default handler's implementation of GetMiscStatus retrieves this information from the registry.
If the object is running, the default handler invokes GetMiscStatus on the object itself.
The default value of MiscStatus is used if a subkey corresponding to the specified DVASPECT is not found.
To set an OLE control, specify DVASPECT==1. This causes the following to occur in the registry:
HKEY_CLASSES_ROOT\CLSID\ . . .\MiscStatus = 1
To determine whether the platform supports this interface, see Determine Supported COM APIs.
Notes to Implementers
Implementation normally consists of delegating the call to the default handler.
