#7 Set file info

[Tom Arn]

There is a File.Info() function that reads the file
properties, but there is no way to modity them.

The (suggested) File.SetInfo() function should allow set
the file properties like attributes and datetimes but of
course the file size and directory flag should be ignored.

Added a file set attribute comand 'setatt'.

e.g. f.setatt("C:\test.txt", file.FILE_HIDDEN)

also added 5 new constants

FILE_HIDDEN
FILE_SYSTEM
FILE_ARCHIVE
FILE_NORMAL
FILE_READONLY

Jim,
I like the function, but not how it is implemented. I think you
should strive for input compatibility with the File.Info frame
output which looks like this for a C:\Autoexec.bat:
{
created:"15-8-02 23:17:59",
archive:true,
directory:false,
modified:"15-8-02 23:18:00",
hidden:false,
accessed:"16-8-02 0:00:00",
size:2134,
system:false,
readonly:false,
}
I.e the user should be able to get the File.Info of a file,
modify one or more of the values (provided this is allowed)
and use the result with as file.Attributes( frame ) to set the
wanted changes.
In general new functions should be as compatible with
existing functions to avoid user confusion and to make
Dialect a messy amalgam of old and new functions. Etc.,
etc. (I could babble on for hours :)

Andr,

again you're right.
(don't you get tired of being right all the time :-))

When I get the (free time) AND (the motivation) I'll make it a
{frame}.

I've tried to implement a file date/time change function but am
having trouble with the C++ FILETIME structure. Some else
want to take a crack at it?

Jim,
You probably can use FileTimeToSystemTime and
SystemTimeToFileTime (kernel32.dll) API calls to tame the
FILETIME structure...
Start to take a look here:
http://www.vbapi.com/vbapi/ref/s/systemtime.html
and look at the 'Used by' references.

In the MFC there is exactly what we need:
CFile::GetStatus gets attributes and datetime of a file,
CFile::SetStatus writes them back.

Here is a little code snipped I took out of a larger function:

setftime() // set file date and time
{
TCHAR unicode1[MAX_PATH]="file1.txt";
CFile f;
CFileStatus status;
int nYear=2002, nMonth=11, nDay=15, nHour=15,
nMin=34, nSec=45;

CTime t(nYear,nMonth,nDay,nHour,nMin,nSec,-1);

if (CFile::GetStatus( unicode1, status ))
{
status.m_mtime = t;
CFile::SetStatus( unicode1, status );
// ok
}
else // not ok
}
