How to get Date and Time with oFTP

[John]

Hi,

i'm using oFTP:Directory("*.*"), but it seems it only returns the name and file size. Is there any way to also retrieve the file's date and time?

Thanks,

John.

John,

Please modify Class TFtp Method Directory this way:

Code: Select all

...
      if ! Empty( oWin32FindData:cFileName )
         AAdd( aFiles, { oWin32FindData:cFileName,;
                         oWin32FindData:nSizeLow,;
                         oWin32FindData:nLastWriteAccess,;
                         oWin32FindData:nCreationTime } )
         while InternetFindNextFile( hFTPDir, @cBuffer )
            oWin32FindData:cBuffer = cBuffer
            AAdd( aFiles, { oWin32FindData:cFileName,;
                            oWin32FindData:nSizeLow,;
                            oWin32FindData:nLastWriteAccess,;
                            oWin32FindData:nCreationTime } )
         end
      endif
...

Hi Antonio,

thanks for the reply. It seems i only get the time returned in this case?

Regards,

John.

John,

What value do you get for oWin32FindData:nLastWriteAccess ?

[John]

Hi Antonio,

i probably did something wrong because i get only empty strings returned for the date and time:

aFtpList:=oFTP:Directory("*.*")
ShowArr(aFtpList)

Function ShowArr(aDirList)
aEval(aDirList,{|i,t| iif(Valtype(i)=="A",(ShowArr(i)),(msgalert(i)) ) })
Return (.t.)

Any suggestions?

Regards,

John.

John,

Please try this:

aFtpList:=oFTP:Directory("*.*")
MsgInfo( Len( aFtpList[ 1 ][ 3 ] ) )

and let me know what you get, thanks

[John]

Antonio,

it returns an 8, but i can't relate that to a file present...

Regards,

John.

John,

It looks like there is something different from a number there.
Please try this:

Code: Select all

aFtpList:=oFTP:Directory("*.*") 
for n = 1 to Len( aFtpList[ 1 ][ 3 ] )
   MsgInfo( Asc( SubStr( aFtpList[ 1 ][ 3 ], n, 1 ) ) )
next

and let me know what you get, thanks

Hi Antonio,

the following files are present in the ftp directory:


I get the following results:
0, 46, 46, 201, 78, 240, 198, 1

Best regards,

John.

[Antonio Linares]

John,

Please copy here the values that you get for each of the four items that you have in the directory, thanks.

[Antonio Linares]

John,

Code: Select all

aFtpList:=oFTP:Directory("*.*")
for m = 1 to Len( aFtpList )
   for n = 1 to Len( aFtpList[ m ][ 3 ] )
      MsgInfo( Asc( SubStr( aFtpList[ m ][ 3 ], n, 1 ) ) )
   next
next

so we can see the eight bytes for each file.

[John]

Antonio,

the values are:
0, 46, 46, 201, 78, 240, 198, 1, 0, 232, 33, 111, 190, 255, 198, 1, 0, 46, 46, 201, 78, 240, 198, 1, 0, 46, 46, 201, 78, 240, 198, 1.

Saludos,

John.

John,

It looks as three files have the same date:

0, 46, 46, 201, 78, 240, 198, 1
0, 46, 46, 201, 78, 240, 198, 1
0, 46, 46, 201, 78, 240, 198, 1
0, 232, 33, 111, 190, 255, 198, 1

From the image that you provided, three have the same date too:

15-10-2006
15-10-2006
15-10-2006
4-11-2006

Now we need to find in what data format the dates are stored.

[Antonio Linares]

The FILETIME structure is a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601.

typedef struct _FILETIME { // ft
DWORD dwLowDateTime;
DWORD dwHighDateTime;
} FILETIME;

Lets see how to get a Clipper date and time from that

[Antonio Linares]

This is the API function to use:

The FileTimeToSystemTime function converts a 64-bit file time to system time format.

BOOL FileTimeToSystemTime(

CONST FILETIME *lpFileTime, // pointer to file time to convert
LPSYSTEMTIME lpSystemTime // pointer to structure to receive system time
);
