IPersistSerializedPropStorage::SetFlags method (propsys.h)

  • Άρθρο

Toggles the property store object between the read-only and read/write state.

Syntax

HRESULT SetFlags(
  [in] PERSIST_SPROPSTORE_FLAGS flags
);

Parameters

[in] flags

Type: PERSIST_SPROPSTORE_FLAGS

The flags parameter takes one of the following values to set options for the behavior of the property storage:

FPSPS_DEFAULT (0x00000000)

Windows 7 and later. The property store object is read/write.

FPSPS_READONLY (0x00000001)

The property store object is read-only.

FPSPS_TREAT_NEW_VALUES_AS_DIRTY (0x00000002)

Introduced in Windows 8. New property values that are added to the property store through the IPropertyStore::SetValue method will cause the IPersistStream::IsDirty method to return S_OK. If this flag is not set, the addition of new property values to the property store does not affect the value returned by IPersistStream::IsDirty.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Read/write is the default setting. IPersistSerializedPropStorage::SetFlags can be called at any time to toggle the read-only and read/write state of the property store.

In versions of Windows before Windows 7, callers can assign a literal zero value directly into the flags parameter to set the read/write state. As of Windows 7, the FPSPS_DEFAULT flag value should be used instead.
