OleRegGetMiscStatus

Returns from the registry miscellaneous information about the presentation and behaviors supported by the specified class. Used by developers of custom DLL object applications to emulate the behavior of the OLE default handler.

HRESULT OleRegGetMiscStatus(

REFCLSID clsid,
//Reference to class identifier
DWORD dwAspect,
//Value specifying aspect of requested class
DWORD * pdwStatus
//Pointer to returned status information
);

Parameters

clsid

Specifies the class whose status information is requested.

dwAspect

Specifies the aspect of the class whose information is requested.

pdwStatus

Points to storage of the returned status information.

Return Values

S_OK

Indicates the status information was returned successfully.

E_OUTOFMEMORY

Indicates there is insufficient memory to complete the operation.

REGDB_E_CLASSNOTREG

Indicates no CLSID is registered for the class object.

REGDB_E_READREGDB

Indicates an error occurred reading the registry.

OLE_E_REGDB_KEY

Indicates the GetMiscStatus key is missing from the registry.

Comments

Object applications can ask OLE to get miscellaneous status information in one of two ways. One way is to call OleRegGetMiscStatus. The other is to return OLE_S_USEREG in response to calls by the default object handler to IOleObject::GetMiscStatus. OLE_S_USEREG instructs the default handler to call OleRegGetMiscStatus. Because DLL object applications cannot return OLE_S_USEREG, they must call OleRegGetMiscStatus rather than delegating the job to the object handler.

OleRegGetMiscStatus and its sibling functions, OleRegGetUserType, OleRegEnumFormatEtc, and OleRegEnumVerbs, provide a way for developers of custom DLL object applications to emulate the behavior of OLE's default object handler in getting information about objects from the registry. By using these functions, you avoid the considerable work of writing your own, and the pitfalls inherent in working directly in the registry. In addition, you get future enhancements and optimizations of these functions without having to code them yourself.
