File questions.......(Tried to look everywhere, nothing.

[RosarioC]

Hello, Now i'm sure you've heard these questions A MILLION TIMES, but i have tried to find somethingon it, even tried to look at the examples, not really getting it.....:-p. anyways, i have a file i created, i wrote text to it and it worked then i tried to write another text to it, nothing.......here it is:

expandcollapse popup

Begining of the file creation:

$FileName = "\DataBase\Database.ext"
$File = FileOpen($FileName,2)

if $File then
   MsgBox(0,"File created" ,"QIGGADY!!")
else
   MsgBox(0,"File not created","Error code: " & @error)
endif


the writing process:

if FileExists($FileName)  then
        $Write = FileWriteLine($FileName,"text")
        $Line2 = FileWriteLine($FileName,"text2")
        FileFlush($File)
           if $Line2 = 1 then
                MsgBox(0,"Line 2 written","QIGGIDY!!!")

                FileClose($fileName)
            endif
        if $Write = 1 then

           MsgBox(0,"This was a triumph, i'm making a note here; huge success","Data Written")




       else
           FileClose($fileName)
           MsgBox(0,"Can't write to file","" &$Write)
        endif
     else
        MsgBox(0,"File not found","" & $FileName)

     endif

Chances are? i'm doing something horribly wrong which doesn't surprise me :-P

If you bother to open the file with

$File = FileOpen($FileName,2)

so why don't you use the $File handle returned in further operations but $FileName?

Try to replace $FileName => $File beneath FileOpen().

Hi RosarioC,

from the help file (FileWriteLine):

Note: Do not mix filehandles and filenames, i.e., don't FileOpen a file and then use a filename in this function. Either use filehandles or filenames in your routines, not both.

That means if you use FileWriteLine with a filename as parameter #1 you do not have to open/close the file by hand!

A-ay

A-ay

but how would it know what mode the file is in? doesn't FileOpen set the mode? i think i saw a FileSetMode once in the help files.......seems to be gone.

Look to the help file:

If a filename is given rather than a file handle, the file will be opened and closed during the function call. For parsing large text files this will be much slower than using filehandles. However, filename will be created if it does not already exist.

Using FileWriteLine with a filename as parameter the file will be opend and closed implizit. And if the file does not exist it will be created.

So either use

$filehandle = FileOpen("test.txt",1)
  FileWriteLine($filehandle, "a text line")
  FileClose($filehandle)

OR use

$filename = "test.txt"
  FileWriteLine($filename, "a text line")
