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.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
