OleRegGetMiscStatus function (ole2.h)

Returns miscellaneous information about the presentation and behaviors supported by the specified CLSID from the registry.

This function is used by developers of custom DLL object applications to emulate the behavior of the OLE default handler.


HRESULT OleRegGetMiscStatus(
  [in]  REFCLSID clsid,
  [in]  DWORD    dwAspect,
  [out] DWORD    *pdwStatus


[in] clsid

The CLSID of the class for which status information is to be requested.

[in] dwAspect

The presentation aspect of the class for which information is requested. Possible values are taken from the DVASPECT enumeration.

[out] pdwStatus

A pointer to the variable that receives the status information.

Return value

This function can return the standard return value E_OUTOFMEMORY, as well as the following values.

Return code Description
The status information was returned successfully.
No CLSID is registered for the class object.
There was an error reading from the registry.
The GetMiscStatus key is missing from the registry.


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.
