how to get data from previous closed file

[Danyfirex]

hi, I'm trying to get a data from a previous closed file, but I can't find the way, I'm not sure about which autoit function use.

this is my code:

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 422, 226, 192, 124)
$Input1 = GUICtrlCreateInput("", 80, 32, 289, 60,$ES_MULTILINE)
GUICtrlSetResizing(-1, $GUI_DOCKAUTO+$GUI_DOCKWIDTH+$GUI_DOCKHEIGHT)
GUICtrlSetTip(-1, "0")
$Input2 = GUICtrlCreateInput("", 80, 120, 289, 21)
$Buscar = GUICtrlCreateButton("Buscar", 120, 168, 73, 33)
$Unir = GUICtrlCreateButton("Unir", 232, 168, 73, 33)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
  Case $GUI_EVENT_CLOSE
   Exit
   case $Buscar
   $file = FileOpen("C:\Users\usuario\Desktop\file.txt", 0)
   fileclose($file)
   $filetwo = fileopen("C:\Users\usuario\Desktop\newfile.txt")
   FileWrite($filetwo, $file)
   fileclose($filetwo)
EndSwitch
WEnd

sorry for my bad english.

Dont close the first file or just reopen the file. You could write the data to an array before you close it I think. Then you could write it from memory.

You're trying to write the file handle of the first file into the second file, not its contents. Also, you've closed the file, so $file doesn't point to anything any more anyways. If you're trying to copy the contents of one file into another, use FileCopy instead of doing it the way you are now.

You are right.

FileWrite($filetwo, $file)

will only write the filehandle. To read the contents, use FileRead() func. No need to FileOpen and FileClose.

Ok thank you, I want to try it.

No need to FileOpen and FileClose.

FileRead automatically determines the encoding, but by using FileOpen you can explicitly declare whether or not the file is ANSI, Unicode etc... so sometimes there is a need for using FileOpen. Plus, if you search the forum their is a discussion about the performance increase by passing the hWnd of the file to FileRead, rather than the filepath.

I wan to try this way, look,

I want to get binary code of my file, and then put it in a new file? but I can't find the way to.

[BrewManNH]

Do you want to merge the first file with another file, or just put it's contents into a new file? If you want to do the second, then use FileCopy, if you want to use the first, use something like this.

$Firstfile = "C:somebinaryfile.bin"
$SecondFile = "C:someotherbinaryfile.bin"
$File1 = FileOpen($FirstFile, 16) ;<<<< Opens file for read in Binary mode
$File2 = FileOpen($Secondfile, 17) ; <<<< Opens file for write/append in Binary mode
$BinaryData = FileRead($File1) ; <<<< Reads the information from File1
FileWrite($File2, $BinaryData) ; <<<< Writes that information to the end of File2
FileClose($File1)
FileClose($File2)

I haven't tested this, but this should work if I haven't screwed anything up.

Ok thank you so much. Finally I made it.

I made this:

$File = FileOpen("C:UsersusuarioDesktop1.txt" , 16)
$st = FileRead($file)
$save = FileOpen("C:UsersusuarioDesktop2.txt", 1)

FileWrite($save, $st)

FileClose($file)
FileClose($save)
