IStorage::SetElementTimes

Sets the modification, access, and creation times of the specified storage element, if supported by the underlying file system.

HRESULT SetElementTimes(

const wchar_t * pwcsName,	//Points to name of element to be changed
FILETIME const * pctime,	//New creation time for element, or NULL
FILETIME const * patime,	//New access time for element, or NULL
FILETIME const * pmtime	//New modification time for element, or NULL
);

Parameters
pwcsName

[in]The name of the storage object element whose times are to be modified. If NULL, the time is set on the root storage rather than one of its elements.

pctime

[in]Either the new creation time for the element or NULL if the creation time is not to be modified.

patime

[in]Either the new access time for the element or NULL if the access time is not to be modified.

pmtime

[in]Either the new modification time for the element or NULL if the modification time is not to be modified.

Return Values
S_OK

The time values were successfully set.

STG_E_ACCESSDENIED

The caller does not have sufficient permissions for changing the element.

STG_E_FILENOTFOUND

The element with the specified name does not exist.

STG_E_INSUFFICIENTMEMORY

The element was not changed due to a lack of memory.

STG_E_INVALIDNAME

Invalid value for the element name.

STG_E_INVALIDPOINTER

The pointer specified for the element was invalid.

STG_E_INVALIDPARAMETER

One of the parameters was invalid.

STG_E_REVERTED

The object has been invalidated by a revert operation above it in the transaction tree.

STG_E_TOOMANYOPENFILES

The element was not changed because there are too many open files.

Comments
This method sets time statistics for the specified storage element within this storage object.

Not all file systems support all of the time values. This method sets those times that are supported and ignores the rest. Each of the time value parameters can be NULL; indicating that no modification should occur.

You can retrieve these time values with the IStorage::Stat method.

Note to Callers
The OLE-provided compound file implementation maintains modification and change times for internal storage objects. For root storage objects, whatever is supported by the underlying file system (or ILockBytes) is supported. The compound file implementation does not maintain any time stamps for internal streams. Unsupported time stamps are reported as zero, enabling the caller to test for support.
