Members

Member	Description
ofRead	Indicates that the file should be opened for reading only.
ofWrite	Indicates that the file should be opened for writing. If you are using the ofWrite flag when opening a .winmd file, you should also pass the ofNoTransform flag.
ofReadWriteMask	A mask for reading and writing.
ofCopyMemory	Indicates that the file should be read into memory. Metadata should maintain its own copy.
ofCacheImage	Obsolete. This flag is ignored.
ofManifestMetadata	Obsolete. This flag is ignored.
ofReadOnly	Indicates that the file should be opened for reading, and that a call to QueryInterface for an IMetaDataEmit cannot be made.
ofTakeOwnership	Indicates that the memory was allocated using a call to CoTaskMemAlloc and will be freed by the metadata.
ofNoTypeLib	Obsolete. This flag is ignored.
ofNoTransform	Indicates that automatic transforms of .winmd files should be disabled. In other words, the projection of a Windows Runtime type to a .NET type should be disabled. For more information, see Windows Runtime and the CLR - Underneath the Hood with .NET and the Windows Runtime.
ofReserved1	Reserved for internal use.
ofReserved2	Reserved for internal use.
ofReserved	Reserved for internal use.
