File cannot be read

[winkot]

I'm trying to open a file via WinAPI

#include <WinAPI.au3>

$File = _WinAPI_CreateFile(@ScriptDir & '\Test.txt', 2)
$Text=FileRead($File)
ConsoleWrite($Text  & @CRLF)
_WinAPI_CloseHandle($File)
Exit

But it still won't read. What's wrong?

Use fileopen() instead of the winapi.

FileOpen() does not allow opening a file for both reading and writing. And that is exactly what I need.

It does, just not at once. But you use set position....

Check out Example 2 of the help file.

I need to read certain lines in a file. And I don't know at what positions the lines start and end. How can I use it in this case FileSetPos?

wincot,

Use FileReadToArray to get the content of the file into a variable and you can then manipulate the array as you wish.

Yes. I also come to the conclusion that it is better to work through arrays. It seems that it is not very convenient to work with Win API functions. Isn't it?

Winkot,

Melba23's suggestion is definitely easier when reading and writing to specific lines. FileOpen can do it, but it gets complex, and can be error prone when reading and writing to multiple lines. My apologies.

Have a good day.
