¿Cómo saber la fecha de los cambios a una carpeta?

[JoseAlvarez]

Amigos,

Necesito saber la ultima fecha en la que una carpeta de windows tuvo cambios.

¿Hay alguna manera?

Estimado José,

Aquí lo tienes. Lo incluimos para el próximo build de FWH:

function FW_FolderChanged( cFolderPath ) --> { nDay, nMonth, nYear, nHours, nMinutes, nSeconds }

Code: Select all | Expand

#include "FiveWin.ch"

function Main()

    XBrowse( FW_FolderChanged( "c:\fwh" ) )

return nil 

#pragma BEGINDUMP 

#include <Windows.h>
#include <hbapi.h>

HB_FUNC( FW_FOLDERCHANGED )
{
   const char * folderPath = hb_parc( 1 );
   FILETIME lastWriteTime;
   WIN32_FILE_ATTRIBUTE_DATA fileAttributes;
   SYSTEMTIME systemTime;

   GetFileAttributesEx( folderPath, GetFileExInfoStandard, &fileAttributes ); 
   lastWriteTime = fileAttributes.ftLastWriteTime;
   FileTimeToSystemTime(&lastWriteTime, &systemTime);

   hb_reta( 6 );
   hb_storvnl( systemTime.wDay, -1, 1 );
   hb_storvnl( systemTime.wMonth, -1, 2 );
   hb_storvnl( systemTime.wYear, -1, 3 );
   hb_storvnl( systemTime.wHour, -1, 4 );
   hb_storvnl( systemTime.wMinute, -1, 5 );
   hb_storvnl( systemTime.wSecond, -1, 6 );
}

#pragma ENDDUMP

Muchas Gracias Master, le daré un vistazo y estaré comentando.

Master Antonio,

Muchas Gracias. Funciona Muy bien, solo necesito resolver un pequeño detalle.
Me da el dato de la hora con la zona horaria de España. En mi caso, son 7 horas mas adelante que mi hora local.

Alguna manera de sincronizarlo con la hora de los demás países?

There is another way:

Code: Select all | Expand

function FolderInfo()

   local oFs   := CreateObject( "Scripting.FileSystemObject" )
   local oFolder  := oFs:GetFolder( "c:\fwh\samples" )

   ? oFolder:DateCreated, oFolder:DateLastModified, oFolder:DateLastAccessed

return nil

You will get your local times.

Time Zone conversions
Here is an example converting our local time to UTC and then NewYork time ( UTC Offset now -5:00 )

Code: Select all | Expand

function TimeZoneConversions()

   local tDateTimeLocal, tDateTimeUTC, tDateTimeNYC

   tDateTimeLocal := HB_DateTime()  // current time
   tDateTimeUTC   := UTC_TIMESTAMP( tDateTimeLocal )  // FWH function
   tDateTimeNYC   := FW_ADDTIME( tDateTimeUTC, "-05:00:00" )

   ? tDateTimeLocal, tDateTimeUTC, tDateTimeNYC

return nil

Converting time in Spain to my local time in India.
We know the current UTC offset of Spain is +1:00 and India's is +5:30

Code: Select all | Expand

tsUTC := FW_AddTime( DateTimeSpain. "-01:00:00" )
tsIndia := FW_AddTime( tsUTC, "05:30:00" )
