How can I open a file for both read and write?

[wzbbbb]

Hi everyone,

I am wondering why there is no function to open a file for both read and write?

There must be a better way for this. Could you please how me ?

Thanks !

Straight out of the help file.

FileOpen

--------------------------------------------------------------------------------

Opens a text file for reading or writing.

FileOpen ( "filename", mode )

Parameters

Filename of the text file to open.

Mode (read or write) to open the file in.

Can be a combination of the following:

0 = Read mode

1 = Write mode (append to end of file)

2 = Write mode (erase previous contents)

4 = Read raw mode

8 = Create directory structure if it doesn't exist (See Remarks).

16 = Force binary(byte) reading and writing mode with FileRead and FileWrite

32 = Use Unicode UTF16 Little Endian mode when writing text with FileWrite and FileWriteLine (default is ANSI)

64 = Use Unicode UTF16 Big Endian mode when writing text with FileWrite and FileWriteLine (default is ANSI)

128 = Use Unicode UTF8 when writing text with FileWrite and FileWriteLine (default is ANSI)

Both write modes will create the file if it does not already exist. The folder path must already exist (except using mode '8' - See Remarks).

Your turn to RTFM.

Ok, I see, it can be a combination. Sorry, for the dumb question.

You don`t have to open the file to read from it or write to it.

$line = FileReadLine("c:\file.txt") ; Read one line to $line

FileWriteLine("c:\file.txt", "Line1"); writes one line to a file

This is a nice think of Autoit3

P.s. Type FileRead and the press F1. Read the letters in the box with "filehandle" paremeter 1. FileRead ( filehandle or "filename" [, count] ) . Help me out this is working in my place!!! .

Read the help your self!

NB: Autoit3 version: 3.2.10.0 Release (25 nov 2007).

Is it a bug in my helpfile and my autoit3?

Out of curiousity... what do you think AutoIt does to the file in order to read it with FileReadLine/FileRead?

Here's a hint... (It opens it )

[Janus]

It findes the filehandle for the file!

And so!

Parameters

filehandle The handle of a file, as returned by a previous call to FileOpen. Alternatively you may use a string filename as the first parameter.

Lets stop this show. You can call Readline() / Writeline with a filehandle OR a string. Thats it!
