File handle returning -1

Recommended Posts

delray

File names, dates and times are returned but $hFile (file handle) always returns -1; why?

#include <GuiConstantsEx.au3>
#include <Date.au3>
#include <WindowsConstants.au3>
; Shows the filenames of all files with .txt extention.
$search = FileFindFirstFile("C:UsersrdwrayCookies*.*")
; Check if the search was successful
If $search = -1 Then
MsgBox(0, "Error", "No files/directories matched the search pattern")
Exit
EndIf
; Get current system time:
$tSys = _Date_Time_GetLocalTime()
$sTime =  _Date_Time_SystemTimeToDateTimeStr($tSys)
While 1
$file = FileFindNextFile($search)
If @error Then ExitLoop
If StringRight($file, 4) = ".txt" then
  $hFile = FileOpen($file) ; Get file handle.
  FileClose($hFile)
  MsgBox(0, 0, "File handle: " & $file & " : " & $hFile)
  $aTime = _Date_Time_GetFileTime($hFile)
  $aDate = _Date_Time_FileTimeToStr($aTime[2])
  If $aTime <> "" Then
   MsgBox(4096, "File:", $file & ": " & $aDate)
  Else
   MsgBox(4096, "File:", "No more files")
  EndIf
EndIf
WEnd

Change your FileOpen command to this:

$hFile = FileOpen("C:Usersrdwray" & $file) ; Get file handle.

You are only opening it by the file name without the path to it, so it doesn't open the file and errors.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

$hFile = FileOpen("C:Usersusername" & $file) ; Get file handle.

Still getting -1:

If StringRight($file, 4) = ".txt" then
  $hFile = FileOpen("C:Usersrdwray" & $file) ; Get file handle.
  FileClose($hFile)
  MsgBox(0, 0, "File handle: " & $file & " : " & $hFile)
  $aTime = _Date_Time_GetFileTime($hFile)
  $aDate = _Date_Time_FileTimeToStr($aTime[2])
  If $aTime <> "" Then
   MsgBox(4096, "File:", $file & ": " & $aDate)
  Else
   MsgBox(4096, "File:", "No more files")
  EndIf
EndIf

Try opening something other than cookie files, because that may be your problem. Also, the folder you're looking in isn't really a folder, it's a junction point, the actual cookies are stored in C:Users<user>AppDataRoamingMicrosoftWindowsCookies.

2 things, I messed up when I copied and pasted your code the first time and second it is now return 2. thanks BrewManNH.

A question now: If the file name is being rerturned, why is the full path required to get the handle?

Because only the file name is returned, you can't open a file by it's file name unless the program can find it. It can't find it if you don't tell it where it is. A file called somerandomname.txt could be anywhere on the hard drive, you have to tell the script where that is.

ok, understand, but a second issue has occurred, the _Date_Time_GetFileTime($hFile) function is failing and returns null in $aDate = _Date_Time_FileTimeToStr($aTime[2]). Should not the file handle be more than 1 digit normally? Matter of fact, it is returning 2 for every file.

You're closing the file after every file open so it reuses the file handle I'm guessing. Also, the _Date_Time_GetFileTime function needs an open file handle to read the information, and you don't give it one because you've closed it. Move the FileClose statement from where it is, to just before the last EndIf statement so that it's not closed until you're done using it.

Still not working:

$path = "C:\Users\username\Cookies\"

While 1
$file = FileFindNextFile($search)
If @error Then ExitLoop
If StringRight($file, 4) = ".txt" then
  $hFile = FileOpen($path & $file) ; Get file handle.
  MsgBox(0, 0, "File handle: " & $file & " : " & $hFile)
  $aTime = _Date_Time_GetFileTime($hFile)
  $aDate = _Date_Time_FileTimeToStr($aTime[2])
  If $aTime <> "" Then
   MsgBox(4096, "File:", $file & ": " & $aDate)
  Else
   MsgBox(4096, "File:", "No more files")
  EndIf
  FileClose($hFile)
EndIf
WEnd

Try using FileGetTime instead of the one you're using. Reading the help file for that function it looks like it has restrictions on how it works, FileGetTime doesn't appear to have those restrictions. Please read the help file in regards to how to use FileGetTime, as it uses a file path and not a handle.

Also, please don't PM me in the future.
