IClassAccess::GetClassInfo

[This is preliminary documentation and subject to change.]

Accesses class information and binaries for a specific class identifier during COM object activation.

Note This method is a subset of GetClassSpecInfo. For most cases, GetClassSpecInfo will be the method used to access class information and binaries.

HRESULT GetClassInfo(
  REFCLSID clsid,             //Class identifier
  QUERYCONTEXT QryContext,    //Query attributes
  PACKAGEINFO* pPackageInfo,  //Pointer to binaries and package information
);

Parameters

clsid: [in] The specific class identifier used to obtain package information and binaries.
QryContext: [in] The query attributes used to obtain package information and binaries.
pPackageInfo: [out] A pointer to the binaries and package information for a specific class identifier.

Return Values

S_OK: The method returned successfully.
E_INVALIDARG: One or more parameters are incorrect.

Comments

The most common method to access the Class container, GetClassInfo queries the directory for implementations for a specific CLSID. If a matching implementation is available for the object type, client architecture, locale, and class context, a pointer to the binaries and package information is returned. If necessary, the binaries are downloaded to the local computer.
