Enum STGM

The STGM enumeration values are used in the IStorage, IStream, and IPropertySetStorage interfaces. These elements are often combined using an OR operator.

[Flags]
public enum STGM

Fields

Name	Description
STGM_CONVERT	Creates the new object while preserving existing data in a stream named "Contents".
STGM_CREATE	Indicates that an existing storage object or stream should be removed before the new one replaces it.
STGM_DELETEONRELEASE	Indicates that the underlying file is to be automatically destroyed when the root storage object is released.
STGM_DIRECT	In direct mode, each change to a storage or stream element is written as it occurs.
STGM_DIRECT_SWMR	The STGM_DIRECT_SWMR supports direct mode for single-writer, multireader file operations.
STGM_FAILIFTHERE	Causes the create operation to fail if an existing object with the specified name exists.
STGM_NOSCRATCH	In transacted mode, a temporary scratch file is usually used to save modifications until the Commit method is called.
STGM_NOSNAPSHOT	This flag is used when opening a storage object with STGM_TRANSACTED and without STGM_SHARE_EXCLUSIVE or STGM_SHARE_DENY_WRITE.
STGM_PRIORITY	Opens the storage object with exclusive access to the most recently committed version.
STGM_READ	Indicates that the object is read-only, meaning that modifications cannot be made.
STGM_READWRITE	STGM_READWRITE allows you to both access and modify an object's data.
STGM_SHARE_DENY_NONE	Specifies that subsequent openings of the object are not denied read or write access. If no flag from the sharing group is specified, this flag is assumed.
STGM_SHARE_DENY_READ	Prevents others from subsequently opening the object in STGM_READ mode. It is typically used on a root storage object.
STGM_SHARE_DENY_WRITE	Prevents others from subsequently opening the object for STGM_WRITE or STGM_READWRITE access.
STGM_SHARE_EXCLUSIVE	Prevents others from subsequently opening the object in any mode. In transacted mode, sharing of STGM_SHARE_DENY_WRITE or STGM_SHARE_EXCLUSIVE can significantly improve performance since they don't require snapshotting.
STGM_SIMPLE	STGM_SIMPLE is a mode that provides a much faster implementation of a compound file in a limited, but frequently used case.
STGM_TRANSACTED	In transacted mode, changes are buffered and written only if an explicit commit operation is called.
STGM_WRITE	STGM_WRITE lets you save changes to the object, but does not permit access to its data.
