Class STGM
The STGM enumeration values are used in the IStorage, IStream, and IPropertySetStorage interfaces. These elements are often combined using an OR operator.
Inheritance
Namespace: Syncfusion.Presentation
Assembly: Syncfusion.Presentation.Portable.dll
Syntax
public sealed class STGM : EnumFields
STGM_CONVERT
Creates the new object while preserving existing data in a stream named "Contents".
Declaration
public const STGM STGM_CONVERTField Value
| Type |
|---|
| STGM |
STGM_CREATE
Indicates that an existing storage object or stream should be removed before the new one replaces it.
Declaration
public const STGM STGM_CREATEField Value
| Type |
|---|
| STGM |
STGM_DELETEONRELEASE
Indicates that the underlying file is to be automatically destroyed when the root storage object is released.
Declaration
public const STGM STGM_DELETEONRELEASEField Value
| Type |
|---|
| STGM |
STGM_DIRECT
In direct mode, each change to a storage or stream element is written as it occurs.
Declaration
public const STGM STGM_DIRECTField Value
| Type |
|---|
| STGM |
STGM_DIRECT_SWMR
The STGM_DIRECT_SWMR supports direct mode for single-writer, multireader file operations.
Declaration
public const STGM STGM_DIRECT_SWMRField Value
| Type |
|---|
| STGM |
STGM_FAILIFTHERE
Causes the create operation to fail if an existing object with the specified name exists.
Declaration
public const STGM STGM_FAILIFTHEREField Value
| Type |
|---|
| STGM |
STGM_NOSCRATCH
In transacted mode, a temporary scratch file is usually used to save modifications until the Commit method is called.
Declaration
public const STGM STGM_NOSCRATCHField Value
| Type |
|---|
| STGM |
STGM_NOSNAPSHOT
This flag is used when opening a storage object with STGM_TRANSACTED and without STGM_SHARE_EXCLUSIVE or STGM_SHARE_DENY_WRITE.
Declaration
public const STGM STGM_NOSNAPSHOTField Value
| Type |
|---|
| STGM |
STGM_PRIORITY
Opens the storage object with exclusive access to the most recently committed version.
Declaration
public const STGM STGM_PRIORITYField Value
| Type |
|---|
| STGM |
STGM_READ
Indicates that the object is read-only, meaning that modifications cannot be made.
Declaration
public const STGM STGM_READField Value
| Type |
|---|
| STGM |
STGM_READWRITE
STGM_READWRITE allows you to both access and modify an object's data.
Declaration
public const STGM STGM_READWRITEField Value
| Type |
|---|
| STGM |
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.
Declaration
public const STGM STGM_SHARE_DENY_NONEField Value
| Type |
|---|
| STGM |
STGM_SHARE_DENY_READ
Prevents others from subsequently opening the object in STGM_READ mode. It is typically used on a root storage object.
Declaration
public const STGM STGM_SHARE_DENY_READField Value
| Type |
|---|
| STGM |
STGM_SHARE_DENY_WRITE
Prevents others from subsequently opening the object for STGM_WRITE or STGM_READWRITE access.
Declaration
public const STGM STGM_SHARE_DENY_WRITEField Value
| Type |
|---|
| STGM |
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.
Declaration
public const STGM STGM_SHARE_EXCLUSIVEField Value
| Type |
|---|
| STGM |
STGM_SIMPLE
STGM_SIMPLE is a mode that provides a much faster implementation of a compound file in a limited, but frequently used case.
Declaration
public const STGM STGM_SIMPLEField Value
| Type |
|---|
| STGM |
STGM_TRANSACTED
In transacted mode, changes are buffered and written only if an explicit commit operation is called.
Declaration
public const STGM STGM_TRANSACTEDField Value
| Type |
|---|
| STGM |
STGM_WRITE
STGM_WRITE lets you save changes to the object, but does not permit access to its data.
Declaration
public const STGM STGM_WRITEField Value
| Type |
|---|
| STGM |
