FileRead problem

[Generator]

Hi everyone, i am new to files, so what i want to do here is open a file, write a number, reads it. But msg box shows nothing when i use filereadline(), or fileread(), any idea how to fix this or make this work?

Thanks in advance.

#NoTrayIcon
#include<file.au3>
Global $i=0
If FileExists(@ScriptDir&"\Screenshots\data\data.dat")=0 Then
DirCreate(@ScriptDir&"\Screenshots\data")
_FileCreate(@ScriptDir&"\Screenshots\data\data.dat")
EndIf
$File=FileOpen(@ScriptDir&"\Screenshots\data\data.dat",2)
FileWrite($File,$i)
$Read=FileReadLine($File,1)
MsgBox(64,"",$Read)

You have to "FileClose" before "FileRead" since you used "FileOpen"

I highly recommend you don't do it this second way if you don't understand exactly what is going on. If you do it wrong, an error in an original function could throw the other functions off causing a massive autoit hard crash.

Thanks for all the helps guys. Especially The Kandie Man.

The data.dat basically is a counter.

That's kind of funny... pseudo code versus telling you what your actual issue is... ahh well ... good one TKM

Lol no worries, one thing i discovered is i never know func can be used this way.

Ex:

FileClose(FileWrite(FileOpen($s_FileName,10),$i))

Thank you too SmOke_N

FileClose(FileWrite(FileOpen($s_FileName,10),$i))

Actually, TKM and I were talking about that before he posted it in MSN. We both had the conclusion since you couldn't get "proper" error handling out of it, that it would probably be better not to show you that you could do that.... guess he changed his mind.

I actually picked up the multiple file functions on one line from Smoke_N.
